                           On Appeal from the Board of Veterans' Appeals


                                     (Decided   June 6, 2003 )



       Ronald L. Smith, of Washington, D.C., was on the pleadings for the appellant.

       Tim S. McClain, General Counsel; R. Randall Campbell, Acting Assistant General Counsel;
Michael A. Leonard, Deputy Assistant General Counsel; and Kate Gorney, all of Washington, D.C.,
were on pleadings for the appellee.

       Before FARLEY, IVERS, and STEINBERG, Judges.

       STEINBERG, Judge: The appellant, Michael D. Cotant, through counsel, seeks review of
an August 21, 2000, decision of the Board of Veterans' Appeals (Board or BVA) that denied his
claim for Department of Veterans Affairs (VA) service connection for degenerative joint disease
(DJD) of the right hip. Record (R.) at 1-9. The appellant filed a brief and a reply brief, and the
Secretary filed a brief.    In response to a February 2002 Court order, the appellant filed a
supplemental brief and a supplemental reply brief, and the Secretary filed a supplemental brief. In
January 2003, the parties filed a joint response to a December 2002 Court order. For the reasons set
forth below, the Court will reverse the Board decision and remand the matter for further proceedings.
                                      I. Relevant Background
        The veteran served on active duty in the U.S. Navy from May 1980 to September 1992, when
he was honorably discharged. R. at 11-17. For his service, his awards included the National Defense
Service Medal and the Navy Expeditionary Medal. R. at 11, 13, 15. His May 1980 Navy entrance
medical examination report noted that the veteran previously had been medically discharged from
the U.S. Army National Guard because of a "bruised hip". R. at 23. Otherwise, except for a request
to examine the veteran for high blood pressure, this May 1980 report indicated that "[a]ll significant
defects, if any, have been evaluated and have been determined to be non-disqualifying." R. at 27.
        On September 21, 1992, the veteran filed an application for VA service connection for, inter
alia, "degenerative/cystic changes of the [right] femoral head." R. at 363-66. A January 1993 VA
regional office (RO) decision deferred consideration of his claim until it had gathered the veteran's
preservice medical records from his private physician, Dr. Donald M. Gentry. R. at 393-95. In
April 1993, the VARO received the veteran's private medical records, dated between 1959 and 1974.
R. at 397-411. A February 1962 entry noted that the veteran had "pain and limp in right hip" and
noted a "history of injury on bicycle last fall." R. at 399. The records also indicated that the veteran
was fitted for a leg brace in 1963. Ibid. A January 1993 VA compensation and pension (C&P)
examination report stated: "Right hip. Patient does have a very significant limp and does note that
he has constant pain there. I will defer the x-rays to the radiologist, but would imagine that he will
begin having problems in his other joints including his knees and other hip secondary to the limp."
R. at 557. There is no subsequent radiological report in the record on appeal (ROA). See
R. at 1-624.
        In a May 1993 decision, the RO denied the veteran's claim for VA service connection for "a
right[-]hip condition" because the evidence showed that "this condition preexisted military duty and
was not permanently aggravated during active duty." R. at 519. The veteran appealed that
determination to the Board in October 1993 (R. at 534); however, the procedural history following
the veteran's appeal is unclear from the ROA (see R. at 1-624). In September 1996, the veteran's
representative forwarded to an RO a letter from Dr. Gentry that stated: "I have reviewed Mike
Cotant's medical record which dates back to when he was a child. It reveals he had Legg[-]Perthes
disease of the right hip before he joined the military service, the result of which left him with


                                                   2
significant degenerative joint changes of the hip[,] which in my opinion was aggravated by the
activities he did in the service." R. at 578. In December 1997, the Board remanded the veteran's
claim to the RO in order to obtain pertinent medical records and conduct an additional VA
examination. R. at 588-93.
       In April 1998, the RO received from Dr. Gentry's office additional private medical records,
dated between 1980 and 1998. R. at 595-602, 613. Dr. Mark R. Rangitsch conducted a VA C&P
examination in June 1998; he diagnosed the veteran as having "Perthes disease of the right hip with
degenerative arthritis of the right hip" and concluded:
               The nature of the leg calf Perthes disease this patient has is consistent
               with the problems he is currently having. The patient['s] developing
               Perthes at 8 years of age and [being] treated with bracing and casting
               has likely developed degenerative arthritis in his hip as time goes
               along. As to whether the pre-existing disease would have manifested
               arthritic changes, this is impossible to entirely say, but it is very
               common for a patient who is diagnosed with Perthes at a late age of
               8 years to develop significant degenerative arthritis. As to whether
               this is accelerated by his military service, it is impossible to say.
               Certainly, the activities he performed could have accelerated the hip
               disease. However, it is most likely that the natural process of his
               disease would have resulted in him developing this hip problem even
               at this early age. This is not uncommon, and I would feel it is more
               likely that the hip disease was due to underlying Perthes disease and
               the natural processes of aging as the disease would progress versus
               being aggravated or significantly increased by his service activities.

R. at 605. The examination report noted that the examiner did not initially have access to the
veteran's medical records (R. at 604), but in January 2000, after reviewing two volumes of the
veteran's medical records, Dr. Rangitsch submitted a supplementary letter in which he concluded:
               [I] feel the degenerative arthritis of the right hip, which is due to pre-
               existing Perthes disease, would likely have occurred even in the
               absence of active military service. I feel it is most likely that the
               underlying disease had went [sic] through a natural aging process,
               which is commonly seen in patients who develop Perthes disease,
               specifically at a later age such as 8, as the patient states was the case.
               Therefore, I would have to continue my opinion that this was a
               natural process of aging and was not significantly aggravated by his
               service-related activities.


                                                   3
(R. at 609).
       In the August 2000 BVA decision here on appeal denying the veteran's claim for service
connection for DJD of the right hip, the Board determined that the veteran's claim for VA service
connection for DJD of the right hip was well grounded within the meaning of section 5107(a) as in
effect at that time. R. at 3. The Board found, pursuant to 38 C.F.R. § 3.304(b) (1999), that clear
and unmistakable evidence demonstrated that the veteran's "right hip arthritis" preexisted service,
even though that disability was not noted during his May 1980 entrance examination. R. at 3, 6. In
making that finding, the Board relied on a March 1980 medical record (not included in the ROA)
from the veteran's private physician that referred to "x-ray evidence of arthritis changes at the head
of the right femur." R. at 6.
       The Board further found, by virtue of the application of the benefit-of-the-doubt rule under
38 U.S.C. § 5107(b), that the "positive evidence was in a state of equipoise with the negative
evidence on the question of whether or not there was an increase in severity of the preexisting
disorder during service" and thus concluded that the veteran's hip condition had increased in severity
during service. R. at 7. The Board then determined that, pursuant to 38 C.F.R. § 3.306 (1999), the
aggravation of his disability was due to the natural progression of the disease:
               A presumption of aggravation arises when there is a finding that a
               preexisting disability increased in severity during service. 38 C.F.R.
               § 3.306. Although the veteran's private physician, Dr. Gentry,
               indicated in a statement that the veteran's condition was aggravated
               by the activities in service, there is no indication that the veteran's
               claims file was reviewed[,] to include service medical records
               [(SMRs)]. In addition, Dr. Gentry gave no rationale or explanation
               for his opinion. In contrast, the VA examiner's opinion concluded
               that the hip disease was due to the underlying Legg-Perthes disease
               and the natural progresses of aging as the disease would progress
               versus being aggravated or significantly increased by his service
               activities. The Board gives more weight to the June 1998 VA
               examiner's opinion, because, unlike the private physician's opinion,
               it was preceded by a thorough clinical examination, which is of
               record, and a review of the claims file[,] to include [SMR]s.
               Moreover, the VA examiner's review of the entire medical record and
               the detailed rationale for the conclusion that the right[-]hip disorder
               underwent a natural progression of the underlying disease, the Board
               finds that the opinions offered by the VA examiner rise to the higher


                                                  4
                  level of clear and unmistakable evidence sufficient to rebut the
                  presumption of aggravation.

R. at 7.


                       II. Contentions of the Parties and Procedural History
           In his June 2001 brief, the appellant argues that the August 2000 BVA decision should be
reversed and the matter remanded to the Board "with an instruction that Mr. Cotant be awarded
service connection." Brief (Br.) at 11-37. The appellant contends that (1) "the Board committed
legal error by finding that the equivocal statements of Dr. Rangitsch were legally sufficient to satisfy
the clear and unmistakable evidence standard of [38 U.S.C. §] 1111" and (2) "the Board further erred
by applying [section] 1153 in a case where the veteran had the benefit of the [section] 1111
presumption of aggravation and the VA had the burden to prove [by clear and unmistakable
evidence] that any disease or injury found to have preexisted service had not been aggravated in
service." Br. at 11-21. In response to a March 2001 order of this Court directing the parties to
address whether an appellant should be permitted to waive consideration on appeal of any rights he
had under the Veterans Claims Assistance Act of 2000, Pub. L. No. 106-475, 114 Stat. 2096 (Nov. 9,
2000) (VCAA), the appellant maintains that such a waiver is permissible and that the Court should
accept his waiver of the consideration of the VCAA in his appeal. Br. at 21-37.
           In his brief, the Secretary argues that the Court should affirm the Board decision; he contends
that the Board correctly applied the section 1153 presumption of aggravation to the appellant's claim
after it determined that the appellant had a preexisting hip condition. Br. at 18. The Secretary argues
that the statutory scheme should be interpreted as follows:
                  Where a veteran enrolls for service, he is taken to be in sound
                  condition [except] for disorders noted or found upon examination, or
                  where clear and unmistakable evidence demonstrates that the injury
                  or disease existed before enrollment and was not aggravated by such
                  service. (38 U.S.C. § 1111). But where there is a preexisting
                  condition, it will be considered to be aggravated by service when
                  there is an increase in disability during such service, unless there is a
                  specific finding that the increase in disability is due to the natural
                  progress of the disease. (38 U.S.C. § 1153).



                                                     5
Br. at 17-18. On the issue of waiver of VCAA consideration on appeal, the Secretary "agrees that
waiver is appropriate in this case." Br. at 8.
        In his reply brief, the appellant contests the Secretary's interpretation of the interplay between
sections 1111 and 1153. He argues as follows:
                  Although both statutes refer to "aggravation" of a preexisting
                  condition, [section] 1111, by its express terms is applicable only in
                  one circumstance, i.e., when a veteran has claimed service connection
                  for a mental or physical disability which was not "noted" at the time
                  of examination, acceptance, and enrollment for service. If the
                  veteran's entrance examination "notes" the disability for which he or
                  she is claiming service connection, [section] 1111 has no application
                  and VA adjudicators must then turn to [section] 1153 to determine
                  whether the disability noted at induction was "aggravated."

Reply Br. at 3.
        In February 2002, the Court issued a supplemental briefing order directing the parties to
address the impact on this case of the opinion of the U.S. Court of Appeals for the Federal Circuit
(Federal Circuit) in Davis (John F.) v. Principi, 276 F.3d 1341 (Fed. Cir. 2002). Cotant v. Principi,
15 Vet.App. 431, 431-32 (2002) (per curiam order). In that opinion, the Federal Circuit applied,
without analysis, section 1153 in a case where the preexisting condition was not noted at entry but,
as provided for in section 1111, had been found to be preexisting by the Board based on clear and
unmistakable evidence, thereby rebutting the presumption of sound condition established by
section 1111. Davis (John F.), 276 F.3d at 1343-44.
        The appellant filed a supplemental brief in March 2002; he argues that Davis (John F.) is
irrelevant to this appeal because the decision did not "address the mutual exclusivity of [section]
1111 and [section] 1153 or construe, in application or otherwise, their relationship to one another."
Supplemental (Suppl.) Br. at 2. The Secretary filed a supplemental brief in April 2002; he argues
that the Federal Circuit's opinion in Davis (John F.) is instructive in clarifying (1) that section 1111
contains only the presumption of soundness, and not an additional presumption of aggravation as
urged by the appellant and (2) that section 1153 establishes and defines the presumption of
aggravation. Suppl. Br. at 6-9. Moreover, the Secretary contends that Davis (John F.) and several
opinions of this Court exemplify that sections 1111 and 1153 have both been applied to a single


                                                    6
claim and are not "mutually exclusive." Suppl. Br. at 11. The appellant filed a reply brief
disagreeing with the Secretary's position and arguing that Davis (John F.) held only that "'evidence
of temporary flare-ups symptomatic of an underlying preexisting condition, alone, is not sufficient
for a non-combat veteran to show increased disability under [section 1153] unless the underlying
condition is worsened.'" Suppl. Reply Br. at 1-2 (quoting Davis (John F.), 276 F.3d at 1346-47).
       On July 30, 2002, the Court issued, sua sponte, an order staying this matter pending the
outcome of Jordan (Timothy) v. Principi, U.S. Vet. App. No. 00-206 (Notice of Appeal (NOA) filed
Jan. 9, 2000) [hereinafter Jordan] or further order of the Court, because the issues involved in the
two cases – regarding proper interpretation of 38 U.S.C. §§ 311 and 353 (1979) (now sections 1111
and 1153, respectively) and the validity of 38 C.F.R. § 3.304(b) (1982) (now 38 C.F.R. § 3.304(b)
(2002)) – are substantially similar. Moreover, the same counsel represents the appellants in the two
cases. In a September 26, 2002, opinion, the Court in Jordan affirmed a November 1999 Board
decision that had determined that there was no clear and unmistakable error (CUE) in an April 1983
Board decision that had denied the appellant's claim for VA service connection for a right-knee
disorder based on a theory of aggravation of a preexisting injury or disease. Jordan v. Principi, No.
00-206, 2002 WL 31163854 (Vet. App. Sept. 26, 2002), withdrawn, 2002 WL 31445159 (Vet. App.
Nov. 1, 2002).     The Court rejected the appellant's statutory-interpretation argument that,
notwithstanding 38 C.F.R. § 3.304(b) (1982), the provisions of 38 U.S.C. § 353 (1979) were
inapplicable to an aggravation claim (1) where the Board had found (in a BVA decision under
collateral attack) that a veteran's condition that had not been noted at entry was preexisting on the
ground that the presumption of sound condition, pursuant to 38 U.S.C. § 311 (1979), had been
rebutted by clear and unmistakable evidence showing that the condition had preexisted service, and
(2) where the Board had denied service connection because it found that the evidence did not support
a finding that the disability had increased in severity during service. Jordan, 2002 WL 31163854,
at *12-14.
       On October 17, 2002, the parties in Jordan filed a joint motion for panel reconsideration
based on newly discovered legislative and regulatory history and recommended that the Court
invalidate 38 C.F.R. § 3.304(b) to the extent that it provides that "the presumption of sound
condition may be rebutted solely by clear and unmistakable evidence that a disease or injury existed


                                                 7
prior to service" – that is, without also requiring clear and unmistakable evidence that the disease
or injury was not aggravated in service. Jordan Joint Motion (Mot.) at 11. On November 1, 2002,
the Court granted that joint motion and withdrew its September 26, 2002, opinion. Jordan, 2002 WL
31445159, at *2 (quoting Jordan Joint Mot. at 11). The Court directed the parties to provide full
copies of all pertinent materials regarding congressional intent in connection with 38 U.S.C. §§ 311
and 353 (1979) and the meaning of the language "and was not aggravated by such service" in
section 311. Jordan, 2002 WL 31445159, at *3. The parties responded on November 18, 2002.
       On December 30, 2002, the Court issued a supplemental briefing order in the instant case
directing the parties (1) to show cause why the Court should not take judicial notice of the
October 17 and November 18, 2002, pleadings filed in Jordan and proceed to decide the
section 311/§ 3.304(b) issue in the instant case; and (2) to include in their responses their views on
the remedy in this case if the Court were to invalidate § 3.304(b) to the extent recommended by the
parties in Jordan.
       The parties filed a joint response on January 10, 2003. In that response, the parties request
that the Court take judicial notice of the October 17 and November 18, 2002, pleadings filed in
Jordan. Joint Response (Resp.) at 3. The joint response states:
               The pleadings discuss the legislative history behind that statute and
               state that the law provides for a two-step process to rebut the
               presumption of sound condition, in that, not only must . . . [VA] find
               by clear and unmistakable evidence that the condition existed prior to
               service, but also, by clear and unmistakable evidence, find that the
               condition was not aggravated therein.

Id. at 4. The joint response further urges:
               In accordance with the pleadings filed in Jordan, the parties ask[] that
               the Court invalidate 38 C.F.R. § 3.304(b), to the extent that it is not
               consistent with [section] 1111. The parties submit that invalidation
               of 38 C.F.R. § 3.304(b) to the extent requested would bear
               significantly on the instant case, as the Board decision on appeal
               made specific findings relying on 38 C.F.R. § 3.304(b), and made
               findings regarding clear and unmistakable evidence on the issue of
               aggravation.




                                                  8
Ibid. The parties request that the Court remand the case for "proper application of the correct law."

                                           III. Analysis
                                         A. VCAA Waiver
        The VCAA, inter alia, amended 38 U.S.C. § 5103 ("Notice to claimants of required
information and evidence") and added 38 U.S.C. § 5103A ("Duty to assist claimants"). VCAA
§ 3(a), 114 Stat. at 2096-98. The Court subsequently issued its opinion in the Holliday case, wherein
the Court held "that all provisions of the VCAA are potentially applicable to claims pending on the
date of the VCAA's enactment." Holliday v. Principi, 14 Vet.App. 280, 286 (2001), mot. for recons.
denied, 14 Vet.App. 327 (per curiam order), mot. for full Court review denied, 15 Vet.App. 21
(2001) (en banc order). Subsequent to the VCAA’s enactment and this Court’s decision in Holliday,
supra, the Federal Circuit issued two opinions addressing retroactive application of the notice and
assistance requirements set forth in VCAA section 3(a). As to cases pending before the Federal
Circuit at the time of the VCAA's enactment, that court held that section 3(a) (amending 38 U.S.C.
§§ 5102, 5103, and 5103A) is not applicable. Bernklau v. Principi, 291 F.3d 795, 803-06 (Fed. Cir.
2002); Dyment v. Principi, 287 F.3d 1377, 1385 (Fed. Cir. 2002). This Court applied those holdings
to cases that were pending before it on the VCAA's enactment date. See Stephens v. Principi,
16 Vet.App. 191, 193 (2002) (per curiam order); Shoffner v. Principi, 16 Vet.App. 208, 215 (2002).
        In this case, the appellant filed his NOA on December 18, 2000, seeking review of the
August 21, 2000, BVA decision. Pursuant to the Court's holding in Juarez v. Principi, the claim
denied by the August 2000 BVA decision was still pending before VA as of the date of the VCAA's
enactment and, thus, the VCAA is applicable to the appellant's claim. Juarez, 16 Vet.App. 518, 521
(2002) (remanding claim pursuant to Holliday, supra, "[b]ecause, as of the November 9, 2000,
enactment of the VCAA, the 120-day judicial-appeal period had not yet expired and the appellant
had not filed an NOA, [and, therefore,] the claims denied by the September 2000 BVA decision were
still pending before VA"). As noted above, the parties agree that the appellant, represented by
counsel here, should be permitted to waive this Court's consideration on appeal of any VCAA rights
that he might have. See Janssen v. Principi, 15 Vet.App. 370, 374 (2001) (holding that claimant


                                                 9
represented by counsel may waive Court consideration on appeal of VCAA protections "if that is his
or her clearly stated, informed, and voluntary desire"). Because we will reverse the Board decision,
however, we need not address that issue.
                               B. Applicable Law and Regulation
       The following are the principal statutory and regulatory provisions involved in the issues on
appeal. Section 1111 of title 38 of the U.S. Code provides:
               § 1111. Presumption of sound condition

                       For the purposes of section 1110 of this title, every veteran
               shall be taken to have been in sound condition when examined,
               accepted, and enrolled for service, except as to defects, infirmities, or
               disorders noted at the time of the examination, acceptance, and
               enrollment, or where clear and unmistakable evidence demonstrates
               that the injury or disease existed before acceptance and enrollment
               and was not aggravated by such service.

38 U.S.C. § 1111. Section 1153 of title 38 of the U.S. Code provides:
               § 1153 Aggravation

                       A preexisting injury or disease will be considered to have
               been aggravated by active military, naval, or air service, where there
               is an increase in disability during such service, unless there is a
               specific finding that the increase in disability is due to the natural
               progress of the disease.

38 U.S.C. § 1153. Regulatory § 3.304(b) provides:
               § 3.304 Direct Service Connection; wartime and peacetime.

                       ....

                      (b) Presumption of Soundness. The veteran will be
               considered to have been in sound condition when examined, accepted
               and enrolled for service, except as to defects, infirmities, or disorders
               noted at entrance into service, or where clear and unmistakable
               (obvious or manifest) evidence demonstrates that an injury or disease
               existed prior thereto. Only such conditions as are recorded in
               examination reports are to be considered as noted.



                                                  10
38 C.F.R. 3.304(b) (2002). Regulatory §3.306(b) provides:
                § 3.306 Direct Service Connection; wartime and peacetime.

                        (a) General. A preexisting injury or disease will be
                considered to have been aggravated by active military, naval, or air
                service, where there is an increase in disability during such service,
                unless there is a specific finding that the increase in disability is due
                to the natural progress of the disease.

                        (b) Wartime service; peacetime service after December 31,
                1946. Clear and unmistakable evidence (obvious or manifest) is
                required to rebut the presumption of aggravation where the preservice
                disability underwent an increase in severity during service. This
                includes medical facts and principles which may be considered to
                determine whether the increase is due to the natural progress of the
                condition. Aggravation may not be conceded where the disability
                underwent no increase in severity during service on the basis of all
                the evidence of record pertaining to the manifestations of the
                disability prior to, during and subsequent to service.

38 C.F.R. 3.306(a), (b) (2002).
                           C. Section 1111 and Regulatory § 3.304(b)
                              1. Judicial Notice of Jordan Pleadings
        The parties urge the Court to take judicial notice of the October 17, 2002, Jordan joint
motion and November 18, 2002, subsequent pleadings. Joint Resp. at 3. The Court may take
judicial notice of "'whatever is generally known within [its] jurisdiction[].'" Brannon v. Derwinski,
1 Vet.App. 314, 316 (1991); see Shephard v. Gober, 10 Vet.App. 486, 487 (1997) (taking judicial
notice of ROA and pleadings filed in concurrent cases); see generally MacMillan Bloedel Ltd. v.
Flintkote Co., 760 F.2d 580, 587 (5th Cir. 1985) (upholding decision of district court to take "judicial
notice of related proceedings and records in cases before the same court"); St. Louis Baptist Temple,
Inc. v. Fed. Deposit Ins. Corp., 605 F.2d 1169, 1171-72 (10th Cir. 1979) (upholding decision of
district court to take judicial notice of prior litigation before it because "[j]udicial notice is
particularly applicable to the court's own records of prior litigation closely related to the case before
it"). In this case, we will take judicial notice of the October 17, 2002, Jordan joint motion and
November 18, 2002, subsequent pleadings because both cases raise the question of the proper


                                                   11
interpretation of sections 1111 and 1153 and the validity of the pertinent part of 38 C.F.R. § 3.304(b)
under that interpretation.
       In the parties' January 2003 joint response, the Secretary joined with the appellant, as he also
ultimately did in Jordan, Jordan Joint Mot. at 11, in urging that the Court "invalidate
38 C.F.R. § 3.304(b), to the extent that it is not consistent with [section] 1111." Joint Resp. at 4.
For the reasons set forth below, however, the Court will decline the Secretary's highly unusual
invitation to invalidate in part his own regulation in § 3.304(b).
                                          2. Section 1111
       In the Jordan joint motion for reconsideration, the parties advised the Court of newly
discovered legislative history in connection with the 1943 enactment of section 9 of Public Law 78-
144, as well as of a 1944 opinion of the chief legal officer of the Veterans' Administration, then
called the Solicitor, interpreting that provision. Joint Mot. at 2. The Jordan joint motion and the
Secretary's November 18, 2002, response to the Court's November 1, 2002, order in Jordan include
material from a 1943 Senate committee report and a floor debate in the House of Representatives
not made available to the Court before submission of the Jordan joint motion. Joint Mot. at 3-10;
Sec'y Nov. 18, 2002, Resp. at Exhibit (Ex.) B (S. REP. NO . 403-78 (1943) [hereinafter 1943
S. REP.]). At that time, the applicable statutory provision, Veterans Regulation No. 1(a) (Reg. 1(a)),
set forth the presumption of soundness:
                      That for the purposes of paragraph I(a) hereof every person
               employed in the active military or naval service for 90 days or more,
               shall be taken to have been in sound condition when examined,
               accepted and enrolled for service except as to defects, infirmities or
               disorders noted at time of examination, acceptance and enrollment,
               or where evidence, or medical judgment is such as to warrant a
               finding that the injury or disease existed prior to acceptance and
               enrollment.

Reg. 1(a), Part I, para. I(b), 38 U.S.C.A. app. ch. 12. The Senate committee report contained an
analysis of the bill as it had been passed by the House. That report indicated that the House had
made the presumption of sound condition irrebuttable (as it had apparently been in section 200 of
the World War Veterans' Act, 1924, as amended) by removing the provision for rebuttal of that
presumption by evidence or medical judgment. 1943 S. REP. at 2, 9. That report also contained the

                                                  12
following statement by the Administrator of Veterans' Affairs (the predecessor of the Secretary of
Veterans Affairs) as to the House-passed amendment:
               [I]t is the view of the Veterans' Administration that elimination of all
               provisions for rebuttal of the presumption of soundness except as to
               defects, infirmities, or disorders noted at time of examination,
               acceptance, and enrollment, is too far-reaching and cannot be
               justified. Even with the greatest of care, medical officers in the
               armed forces cannot possibly discover all existing diseases or
               disabilities and since compensation or pension is payable for
               aggravation of preexisting disabilities under Veterans Regulation No.
               1(a), as amended, it seems only fair that the Government should be
               properly safeguarded so that payment of compensation or pension
               will be made only for disabilities incurred in service, or aggravation
               of disabilities which the person had when he entered the service, even
               though such disabilities may not have been noted at the time of
               examination, acceptance, or enrollment.

1943 S. REP. at 6. The Administrator then recommended to the Senate committee the insertion into
the statute of "or where clear and unmistakable evidence demonstrates that the injury or disease
existed prior to acceptance and enrollment." Ibid. The committee not only added this language,
thereby making the presumption of soundness "rebuttable", but also added "'and was not aggravated
by such active military or naval service' to make clear the intention to preserve the right in
aggravation cases." Id. at 2.
       When the Senate-amended bill returned to the House for consideration, the "not aggravated"
language was a specific focus of debate. The following exchange occurred between Representative
Judd and Representative Rankin, then the Chairman of the House Committee on Veterans' Affairs:
               Mr. JUDD. I think it is much better as it is except for one word, and
               I admit I do not know how to correct it. That word "aggravate" is
               administratively impossible. How can a doctor prove that a thing has
               not been aggravated by the man's service, or how many veterans will
               ever admit that it was not aggravated? "Aggravate" is a matter of
               degree, and usually impossible to measure.

               Mr. RANKIN. I understand.

               Mr. JUDD. I do not know how any doctor is going to be able to
               prove one way or the other.


                                                 13
               Mr. RANKIN. I will say to the gentleman that the word "aggravate"
               is now sanctified by time and usage. It has been in the veterans' law
               ever since the last World War. If a man went into the service in the
               last war with a disability and that disability was aggravated by his
               service his disability was held to be service-connected. For instance,
               we will take a case in the present war. A man comes in with a
               nervous tendency that is not pronounced enough to cause the Army
               to reject him, or the Navy to reject him, but he goes through Pearl
               Harbor or he is on a vessel that is bombed and men are killed all
               around him and the ship is blown to pieces[;] it might aggravate that
               disability without touching him. It might aggravate his condition to
               such an extent that he would be a total nervous wreck. Then he
               should be entitled to hospital care and such other benefits as are
               provided for service-connected disabilities.

               Mr. JUDD. I think the gentlemen is right in agreeing to make this bill
               provide the burden of proof shall be upon the Government to show
               that the condition did exist previous to entry into service, rather than
               having the burden of proof on the veteran to show that it did not exist
               before he entered the service. That is the fair thing to do, just like in
               baseball where a tie is decided in favor of the runner. There ought to
               be a presumption in favor of the veteran in this case as well.

                      But, with the word aggravated in there it is going to be almost
               impossible ever to keep some from getting pensions that ought not to
               get them.

               Mr. RANKIN. So far as the word aggravated is concerned, as a
               practicable proposition, it is not subject to a doctor['s] technical
               diagnosis or doctor['s] medical terminology, as used by an
               experienced physician such as the gentleman from Minnesota would
               give it in writing up his report on a special case involving a technical
               diagnosis.

               Mr. JUDD. I understand.

Sec'y Nov. 18, 2002, Resp., Ex. C (1943 CONG . REC. 7165 (1943)).
       Subsequently, on February 7, 1944, the VA Solicitor issued an opinion contemporaneous
with the enactment of the new language in section 9 of the new Public Law. That opinion interpreted
the new section, in pertinent part, as follows:



                                                  14
As to noted disabilities the section is silent as to how the question of
aggravation shall be adjudicated. However, as to those defects or
disorders which were not noted but where clear and unmistakable
evidence demonstrates that they existed prior to acceptance and
enrollment the section, as amended, requires that any finding to the
effect such preexisting defect or disorder was not aggravated must be
demonstrated by clear and unmistakable evidence. In other words, as
far as the specific language of the amendment is concerned, the only
cases in which aggravation must be rebutted by clear and
unmistakable evidence are those in which the defect or disorder was
not noted. As to noted disabilities a specific finding that the increase
is due to the natural progress of the disease as provided in 1 (a), Part
I, Veterans Regulation 1 (a), is sufficient to deny the claim.

       ....

        The mandate of the statute as to the manner in which
aggravation must be refuted in those cases where there was a pre-
existing injury or disease not noted at time or enlistment may be
said to create a rebuttable presumption of soundness with a
provision that even where rebutted by clear and unmistakable
evidence, there is a presumption of aggravation which itself is
rebuttable but only by clear and unmistakable evidence. To this
extent clearly[,] Paragraph 1 (d) relating to aggravation of a disease
or injury pre-existing at enlistment or induction is modified.

       ....

        . . . The matter really resolves itself into prescribing
administratively what proof is acceptable and I can seen no valid
reason, legal or otherwise, for the Administrator attempting to
differentiate as between 1(d) [now section 1153] and 9(b) [now
section 1111], especially when as has been represented, unless such
practice is adopted[,] the administrative difficulties presented will be
so confounding as to impede and forestall an effective and
expeditious administration of the law. Further, since the principles
relied upon formerly in both section 1(b) and (d) [now section 1153]
were limited, if not eliminated, by the amendment to (b), it would
seem the [better] part of wisdom – even though literally not requisite
under accepted rules of construction – to approximate the permissive
procedures under (d) [now section 1153] to those required by (b) as
amended. If there were any doubt as to this, the legislative history,
both written and otherwise, leaves no doubt as to the purpose of the
legislators to establish service connection by way of aggravation of

                                  15
               a pre-existing disability, noted or not noted, if the Government later
               discharged the person for such disability. The law should be
               administered in light of such purpose, even though one may innately
               harbor reservations as to the soundness of the underlying reasons.

                       Subject to the above observations, it seems to me that your
               question may be answered in the affirmative, namely, that where the
               requisite proof is available a [sic] showing that the person's
               condition on discharge was the same as at time of enlistment or
               induction, such showing would constitute clear and unmistakable
               evidence that there was no aggravation of his disability. This would
               be true either under 1 (d) [now section 1153] or 9 (b) [now section
               1111].

Sec'y Nov. 18, 2002 Resp., Ex. F (72 Op. Sol. 298, 300-02 (1944)) (emphasis added).
       The foregoing materials provide justification for the parties' position that § 3.304(b) conflicts
with the section 1111 presumption of sound condition. The regulatory history of § 3.304(b),
however, is not quite so persuasive.
                                       3. 38 C.F.R. § 3.304(b)
       There are numerous factors that have led the Court to the conclusion that, rather than
invalidate § 3.304(b), we should instead send this issue back to the Secretary to resolve. Although
the legislative history of section 1111 is well documented, see part III.B.2., above, the regulatory
history of § 3.304(b) is more enlightening for what it does not provide than for what it does provide.
        The implementing regulation for the forerunner of section 1111 was found in VA Regulation
1063 (1946). Paragraph (B) of that regulation specifically included the "not aggravated" clause
consistent with the 1943 Public Law:
                       (B) For the purposes of paragraph 1(a), Part I, Veterans
               Regulation No. 1(a), as amended July 4, 1943, every person employed
               in active service shall be taken to have been in sound condition when
               examined, accepted and enrolled for service except as to defects,
               infirmities or disorders noted at the time of the examination or where
               clear and unmistakable evidence demonstrates that the injury or
               disease existed prior to acceptance and enrollment and was not
               aggravated by such service.




                                                  16
Sec'y Nov. 18, 2002, Resp. at Ex. G (emphasis added). The crucial "not aggravated" language was
repeated in paragraph (D), which provided in full:
                       (D) "Clear and unmistakable" means obvious or manifest.
               Accordingly, evidence which makes it obvious or manifest, [sic] that
               the injury or disease under consideration existed prior to acceptance
               and enrollment for service will satisfy the requirements of the statute.
               The requirement of the law is that claims to which the above cited
               presumptions apply may be denied only on the basis of evidence
               which clearly and unmistakably demonstrates that the disease did not
               originate in service, or, if increased in service, was not aggravated
               thereby.

Ibid. (emphasis added). Further clouding the picture regarding the closing reference in the above
quotation to "increased in service" was paragraph (I), which provided, in pertinent part, the following
as to "increase in service", a factor that had not been addressed at all in the 1943 Public Law:
                       (I) Under Regulation I (a), Part I, paragraphs 1(a), (b) and (d),
               as amended July 13, 1943, injury or disease, apart from misconduct
               disease, noted prior to service or shown by clear and unmistakable
               evidence, including medical facts and principles, to have had
               inception prior to enlistment will be conceded to have been
               aggravated where such disability underwent an increase in severity
               during service unless such increase in severity is shown by clear and
               unmistakable evidence, including medical facts and principles, to
               have been due to the natural progress of the disease. Aggravation of
               a disability noted prior to service or shown by clear and unmistakable
               evidence, including medical facts and principles, to have had
               inception prior to enlistment may not be conceded where the
               disability underwent no increase in severity during service on the
               basis of all the evidence of record pertaining to the manifestations of
               such disability prior to, during and subsequent to service. . . .

Ibid. (emphasis added). As the analysis below will show, the italicized language as to "increase in
service" does not mesh with the sections 1111/1153 issues raised by the parties.
       In 1949, VA Regulation 1063 was codified into 38 C.F.R. § 3.63; paragraphs (B), (D), and
(I) in that regulation were identical to the 1946 provisions quoted above. 38 C.F.R. § 3.63 (1949).
Although there were intervening changes to these § 3.63 paragraphs between 1949 and 1956, none
of the changes were pertinent to the language of concern at this point. In February 1961, VA


                                                  17
promulgated a mammoth recodification of title 38 of the C.F.R. Inexplicably, the language "and
was not aggravated by service" disappeared from the then-new § 3.304 and most of what had been
paragraph (D) was dropped. 38 C.F.R. § 3.304 (Supp. 1962). The Federal Register contains no
explanation for the language deletions; it contains only the recodified title 38, without any
explanation as to the reason for the recodification. See 26 Fed. Reg. 1561 (Feb. 24, 1961). In what
appears to be a VA internal document, the then-new § 3.304(b) and § 3.306(b) were described as a
"Restatement of VA Regulation 1063 (B), (D), and (E)" and as a "Restatement of VA Regulation
1063 (I)", respectively; also, § 3.306(a) was explained as a "Restatement of VA Regulation 1063 (I)."
Sec'y Nov. 18, 2002, Resp. at Ex. K (VA C & P Transmittal Sheet 209). Regulation § 3.304(b) and
§ 3.306(b) have not been significantly revised since 1961.
       Hence, the initial VA regulations adopted to implement the 1943 Public Law carried the "not
aggravated" add-on as part of the forerunner of § 3.304(b) for 15 years until that language
mysteriously disappeared in what was denominated a technical recodification. See Kilpatrick v.
Principi, 327 F.3d 1375, 1382 (Fed. Cir. 2003) (reiterating with citations "the venerable principle
that it is improper to interpret a codification as making substantive changes in the law absent a clear
indication in the legislative history"). The parties failed to call this language disappearance to the
Court's attention in either the Jordan or Cotant pleadings. (The Court notes that the Secretary
merely stated: "The provisions in §§ 3.304, 3.306 have not undergone any significant change since
1961." Sec'y Nov. 18, 2002, Jordan Resp. at 5 (emphasis added)). Additionally, the sentence
beginning "Aggravation may not be conceded" in § 3.306(b), to which regulation that language was
transferred in the 1961 recodification of title 38 of the C.F.R., appears totally superfluous in the
present text of the regulation, given the preceding sentence requiring an "increase in severity"; the
sentence made sense only in the context of the "and was not aggravated" language that was part of
the 1949 wartime presumption of sound condition. Yet, the parties, although calling attention to
what they perceived as "an apparent conflict" between the 1944 Solicitor's opinion and the "increase
in severity language", Sec'y Nov. 18, 2002, Jordan Resp. at 5, also failed to explain how the Court
could invalidate only § 3.304(b) without also addressing the requirement of an increase in severity
that § 3.306(b) appears to require in wartime (and post-1947) cases and the apparent conflict with
what the parties assert section 1111 means (conceivably the last two paragraphs of the Solicitor's


                                                  18
1944 opinion quoted in part III., C.2., above, provide some enlightenment on this perceived
disconnect).
        In addition, the Court notes that were it to have applied section 1111 as the parties have
urged, it would appear that the result would not be a finding of aggravation but rather a finding that
the veteran entered service in sound condition by virtue of the presumption of sound condition not
having been rebutted. That is literally what section 1111 appears to provide for, not a finding of
aggravation. This in turn would lead to somewhat anomalous results as between noted-at-entry and
not-noted-at-entry preexisting conditions. As a result of 38 C.F.R. § 3.322(a) and § 4.22, the rating
of a condition found to be service connected on the basis of aggravation is derived by "deduct[ing]
from the present degree of disability the degree, if ascertainable, of the disability existing at the time
of entrance into active service." 38 C.F.R. §§ 3.322(a), 4.22 (2002). In a case where, for example,
a preexisting condition was noted and rated at 20% at entry, only a 50% rating would be awarded
if that condition were later determined to have increased in severity to a 70% rating. However, if
the preexistence were not noted at entry, then a 70% rating would be awarded unless the rating at
entry were ascertainable – something that would appear to be a relatively rare phenonenom for a not-
noted-at-entry condition. See 38 C.F.R. §§ 3.322(a), 4.22. Under §§ 3.322(a) and 4.22, however, in
the case of a 100% current disability rating, no deduction would be made; so, for example, a veteran
with a condition that was 50% disabling at entry and is rated 100% now would get a 100% (not a
50%) rating.
        Because these potential disparities might be considered "absurd" results, they provide still
further reason why the Court is presently not inclined to make a firm holding as to the interpretation
of section 1111 and the invalidation of § 3.304(b) urged by the parties. See United States v. X-
Citement Video, Inc., 513 U.S. 64, 68-69 (1994) ("Some applications of respondents' position [as to
the proper construction of Protection of Children Against Sexual Exploitation Act] would produce
results that were not merely odd, but positively absurd. . . . We do not assume that Congress, in
passing laws, intended such results."); Green v. Bock Laundry Mach. Co., 490 U.S. 504, 509 (1989);
United States v. Am. Trucking Ass'ns, Inc., 310 U.S. 534, 543 (1940); Allen (William) v. Principi,
237 F.3d 1368, 1375-76 (Fed. Cir. 2001); Timex V.I., Inc. v. United States, 157 F.3d 879, 886 (Fed.
Cir. 1998); Thayer v. Principi, 15 Vet.App. 204, 210 (2001); Holliday, 14 Vet.App. at 285 (citing


                                                   19
precedent regarding need to avoid absurd result when interpreting statute); Cottle v. Principi,
14 Vet.App. 329, 334 (2001); Faust v. West, 13 Vet.App. 342, 350 (2000); Trilles v. West,
13 Vet.App. 314, 324 (2000) (en banc); Davenport v. Brown, 7 Vet.App. 476, 483-84 (1995);
Gardner v. Derwinski, 1 Vet.App. 584, 587 (1991).
        Accordingly, the Court has determined that the problems with the Secretary's regulations run
far deeper than the limited § 3.304(b) remedy sought by the parties. Because, as concluded in part
III.D., below, the Court need not deal with § 3.304(b) in order to review the BVA decision on appeal
and provide the remedy sought by the appellant, the Court will not address definitively the section
1111/1153 issues raised by the parties and the extent to which § 3.304(b) may not be consistent with
the statutory scheme. Instead, the task of straightening out this extraordinarily complicated and
tangled web of apparently conflicting statutory and regulatory provisions will be left to the Secretary.
See Zang v. Derwinski, 8 Vet.App. 246, 255 (1995) (Steinberg, J., separate views) (citing, inter alia,
Talley v. Derwinski, 2 Vet.App. 282, 285-86, 288 (1992), and Hattlestad v. Derwinski, 1 Vet.App.
164, 167 (1991), referring to "'confusing tapestry' of VA regulations which should be the subject of
review and reevaluation by the Secretary"); see also Maggitt v. West, 202 F.3d 1370, 1377 (Fed. Cir.
2000) (holding that although this Court "may hear legal arguments raised for the first time with
regard to a claim that is properly before the Court, it is not compelled to do so in every instance");
cf. 57 Fed. Reg. 59, 296 (Dec. 15, 1992) (issuing final regulation in order to conform § 3.306 to 1974
statutory amendment regarding service after December 31, 1946).
                 D. The Board's Application of § 3.306 to the Appellant's Claim
        As set forth in part III.B.2., above, regulatory § 3.306(b) provides, inter alia, that clear and
unmistakable evidence is required to rebut the presumption of aggravation where the preservice
disability underwent an increase in severity during service. 38 C.F.R. § 3.306(b). The determination
whether the record contained clear and unmistakable evidence of sufficient weight to rebut the
presumption of aggravation under § 3.306(b) is subject to de novo review by this Court. See Crowe
v. Brown, 7 Vet.App. 238, 247 (1994) (citing Bagby v. Derwinski, 1 Vet.App. 225, 227 (1991); see
also Miller v. West, 11 Vet.App. 345, 347 (1998) (citing Bagby, supra, and applying de novo review
to review of rebuttal of section 1111 presumption of sound condition by clear and unmistakable
evidence); Junstrom v. Brown, 6 Vet.App. 264, 266 (1994); Kinnaman v. Principi, 4 Vet.App. 20,


                                                  20
27 (1993); cf. Doran v. Brown, 6 Vet.App. 283, 286 (1994) (concluding that 38 U.S.C. § 7261(a)(4)
"clearly erroneous" standard of review is applicable to Board determination under 38 U.S.C. § 1153
and 38 C.F.R. § 3.306(a) that preexisting condition had not increased in severity during service).
The clear-and-unmistakable-evidence standard is an "onerous" one, Laposky v. Brown,
4 Vet.App. 331, 334 (1993) (citing Akins v. Derwinski, 1 Vet.App. 228, 232 (1991)), and requires
that the no-aggravation result be "undebatable", Vanerson v. West, 12 Vet.App. 254, 258, 261
(1999); id. at 263 (Nebeker, C.J., concurring in part and dissenting in part).
        In this case, the Board first found that the appellant's preexisting hip condition had increased
in severity during service, thereby triggering a presumption of aggravation under § 3.306. R. at 6-7.
The Board determined that more "weight" should be given to the opinion of the VA examiner,
Dr. Rangitsch, than that of the veteran's private physician, Dr. Gentry, because that VA examiner's
opinion "was preceded by a thorough clinical examination" and a review of the veteran's SMRs, and
the Board thus found that the presumption of aggravation had been rebutted because Dr. Rangitsch's
opinion "[rose] to the higher level of clear and unmistakable evidence" necessary to rebut the
presumption of aggravation. R. at 7. The Court concludes that this determination of the Board was
erroneous.
        First, the Board did not reject as lacking in credibility Dr. Gentry's opinion that the veteran's
condition was aggravated by his activities in service. Rather, it gave "more weight to the June 1998
VA examiner's opinion", that of Dr. Rangitsch. R. at 7 (emphasis added). Second, Dr. Rangitsch's
rather equivocal opinion, even standing alone, was far from the kind of unconditional evidence
necessary to meet the very demanding clear-and-unmistakable-evidence standard. See Vanerson,
supra; see also Harris v. West, 11 Vet.App. 456, 462 (1998) (holding that physician's unequivocal
and uncontradicted opinion regarding the appellant's disability constituted clear and unmistakable
evidence that rebutted presumptions of soundness and aggravation). Indeed, Dr. Rangitsch stated
his opinion with five distinct qualifications: (1) "As to whether this [DJD of the right hip] is
accelerated by his military service, it is impossible to say"; (2) "[c]ertainly the activities he
performed could have accelerated his hip disease"; (3) "it is most likely that the natural process [sic]
of the disease would have resulted in hi[s] developing this hip problem even at an early age"; (4) "I
would feel it is more likely that the hip disease was due to the underlying Perthes disease and the


                                                   21
natural processes of aging as the disease would progress"; and (5) the DJD of the right hip was "not
significantly aggravated by his service-related activities". R. at 605 (emphasis added). Moreover,
Dr. Rangitsch reiterated two of the above qualifications in his January 2000 supplemental report.
R. at 609 ("most likely" and "not significantly aggravated").      Third, Dr. Gentry opined: "Mike
Cotant's medical records . . . reveal [that] he had Legg[-]Perthes disease of the right hip before he
joined the military service, the result of which left him with significant degenerative joint changes
of the hip which in my opinion was aggravated by the activities he did in the service." R. at 578.
       Reviewing the evidence de novo under Bagby, supra, the Court holds that the record does
not provide clear and unmistakable evidence that the appellant's increase in his right-hip disability
was due to the natural progression of his DJD of the right hip. See 38 C.F.R. § 3.306(b); Crowe and
Bagby, both supra. Accordingly, because the Board found that clear and unmistakable evidence
demonstrated that the appellant's right-hip disability preexisted service and found also that that
disability had increased in severity during service (R. at 3,6,7), findings not challenged on appeal,
we hold that the evidence as to natural progress of that preexisting condition does not show clearly
and unmistakably that that increase found by the Board was "due to the natural progress of the
disease", 38 C.F.R. § 3.306(a), and, therefore, that that preexisting disability must be considered to
have been aggravated "by . . . service." Ibid. We must thus reverse the Board conclusion as to
aggravation and direct that a finding of aggravation be entered. 38 C.F.R. § 3.306(b); see Crowe and
Bagby, both supra.
       In reaching the above decision to reverse as to aggravation in this case, we are mindful of the
principles so cogently set forth by our recently retired colleague, Judge Holdaway, in Vanerson:
               Pursuant to the duty to assist, the Secretary is required to assist the
               claimant "in developing the facts pertinent to the claim"; that duty
               must be performed without regard to whether the evidence supports
               or detracts from the claim. Once the claim has been developed, the
               Secretary is required to make an impartial decision affording the
               claimant the benefit of the doubt where the evidence is in equipoise.
               The typical parley of "basic facts" and "counter proof" involved with
               presumptions in an adversarial proceeding does not fit the VA
               adjudication system where the very adjudicator, who is charged with
               assisting in the development of the claim, would also bear the burden
               of rebutting the presumption. . . .


                                                 22
                       Additionally, the standard of proof for rebutting the
                presumption of soundness is not merely evidence that is cogent and
                compelling, i.e., a sufficient showing, but evidence that is clear and
                unmistakable, i.e., undebatable. . . . [and] the question is not whether
                the Secretary has sustained a burden of producing evidence, but
                whether the evidence as a whole, clearly and unmistakably
                demonstrates that the injury or disease existed prior to service.

Vanerson, 12 Vet.App. at 261. Here, the same standard of proof applies to the evidence as to natural
progression of the condition for purposes of assessing aggravation, and we have no doubt that the
evidence fails to demonstrate clearly and unmistakably – that is, undebatably – that the increase in
severity during service of the veteran's preexisting right hip condition was not due to the natural
progress of the disease. See 38 C.F.R. § 3.306(b); Crowe and Bagby, both supra. Accordingly,
having concluded that the appellant is entitled to the § 3.306 presumption of aggravation, we turn
to the issue of service connection.
                                       E. Service Connection
        In order for a preexisting condition aggravated in service to be found to be service connected,
the three so-called Caluza elements must be satisfied. See Rose v. Principi, 11 Vet.App. 169, 172
(1998) (applying three elements for service-connection claim from Caluza v. Brown, 7 Vet.App. 498,
506 (1995) (holding that claim required "competent evidence [(1)] of current disability (a medical
diagnosis)[,] . . . [(2)] of incurrence or aggravation of a disease or injury in service (lay or medical
evidence)[,] . . . and [(3)] of a nexus between the in-service injury or disease and the current
disability (medical evidence)"), aff'd per curiam, 78 F.3d 604 (Fed. Cir. 1996) (table)). The
determination of service connection is a finding of fact determined under the "clearly erroneous"
standard of review set forth in 38 U.S.C. § 7261(a)(4). See Rose, 11 Vet.App. at 172; Russo v.
Brown, 9 Vet.App. 46, 53 (1996). The last Caluza element, nexus, may be shown under 38 C.F.R.
§ 3.303(b), as discussed below, by chronicity or continuity of symptomotology. See Rose,
11 Vet.App. at 171. Under § 3.303(b), if "chronic disease [is] shown as such in service (or within
the presumpt[ion] period under § 3.307) so as to permit a finding of service connection, [then]
subsequent manifestations of the same chronic disease at any later date, however remote, are service
connected, unless clearly attributable to intercurrent causes"; the regulation further declares that
"[w]hen the disease identity is established . . . , there is no requirement of [an] evidentiary showing

                                                  23
of continuity." 38 C.F.R. § 3.303(b) (2002); see Savage v. Gober, 10 Vet.App. 488, 494-95, 498
(1997).
          The Board addressed two of the Caluza elements of service connection. As to the first
Caluza element, the Board found sufficient evidence of a current disability to conclude that the
service-connection claim was well grounded under then-section 5107(a) (the requirement of a well-
grounded claim previously set forth in 38 U.S.C. § 5107(a) was repealed by VCAA § 4, 114 Stat.
at 2098). R. at 3 (finding "a current medical diagnosis of [right-hip] disability"). Although there
appears to be no evidence after January 2000 pertaining to current disability, this Board finding and
the medical evidence of a disability relatively contemporaneous with the BVA decision (R. at 605,
609) would satisfy the Caluza requirement of current disability, especially because there is no
medical evidence of record to the contrary and no dispute that the veteran had the disease at that
time. See Caffrey v. Brown, 6 Vet.App. 377, 381 (1994) (assessing contemporaneousness of medical
diagnosis in terms of date of BVA decision and concluding that medical examination conducted
23 months prior was not contemporaneous with BVA decision). As to the second Caluza element,
our holding here provides the finding of in-service aggravation of a preexisting right-hip condition,
which the Board characterized as "right[-]hip arthritis". R. at 6.
          As to the third Caluza element of nexus, however, even though the veteran applied for
service connection on September 21, 1992, one month after his separation examination, there
appears to be no medical evidence in the record linking the current disability to the in-service
aggravation of his condition. Cf. Hampton v. Gober, 10 Vet.App. 481 (1997) (holding that Caluza
nexus requirement was met by evidence of record regarding separation examination and VA
examination two months later, both of which referenced bilateral knee condition). In this case, a
medical nexus opinion is lacking; that lack of medical evidence of nexus, however, is not fatal to the
appellant's service-connection claim.
          Regulation § 3.303(b), relating to chronicity or continuity of symptomatology, "provides an
alternative method of demonstrating entitlement to service connection." Rose, 11 Vet.App. at 171
(citing Savage, 10 Vet.App. at 495-96 (concluding that § 3.303(b) provides a "substitute way of
showing in-service incurrence and medical nexus for purposes of well grounding . . . a claim");
38 C.F.R. § 3.309(a) (2002) ("[a]rthritis" denominated as "chronic disease" for purposes of one-year


                                                  24
presumption of service connection established by 38 C.F.R. § 3.307(a)(2) for chronic diseases).
Because the question of continuity of symptomatology or chronicity for purposes of determining
service connection of the veteran's currently diagnosed "degenerative arthritis of the right hip"
(R. at 605) has not been addressed by the Board, the Court will remand the question of service
connection to the Board for it to address in the first instance. See, e.g., Myers v. Principi,
16 Vet.App. 228, 236 (2002) (remanding effective-date issue to Board because of possibility that
"not all of the material that may bear on this question was included in the ROA").


                                         IV. Conclusion
       Upon consideration of the foregoing analysis, the ROA, and the submissions of the parties
here and those from Jordan of which we have taken judicial notice, the Court reverses the
August 21, 2000, BVA decision on the question of aggravation and remands the matter for the entry
of a finding of aggravation and a determination (1) of the issue of service connection and (2) if
service connection is awarded, of the appropriate rating and effective date, in a decision supported
by an adequate statement of reasons or bases, see 38 U.S.C. §§ 1110, 1111, 5100-5103, 5103A,
5106, 5107, 5110(a), 7104(a), (d)(1); 38 C.F.R. § 3.306(b); Fletcher v. Derwinski, 1 Vet.App. 394,
397 (1991) – all consistent with this opinion and in accordance with section 302 of the Veterans'
Benefits Improvements Act of 1994, Pub. L. No. 103-446, § 302, 108 Stat. 4645, 4658 (1994) (found
at 38 U.S.C. § 5101 note) (requiring Secretary to provide for "expeditious treatment" for claims
remanded by BVA or the Court). See Allday v. Brown, 7 Vet.App. 517, 533-34 (1995). On remand,
the appellant will be free to submit additional evidence and argument on the remanded claim in
accordance with Kutscherousky v. West, 12 Vet.App. 369, 372-73 (1999) (per curiam order)
(concluding that an appellant is entitled, until 90 days after Board mails postremand notice to
appellant, to submit additional evidence and argument or to request hearing on appeal at which
appellant may submit new evidence), and such evidence and argument must be considered on
remand. See Kay v. Principi, 16 Vet.App. 529, 534 (2002). The Court notes that a remand by this
Court and by the Board confers on an appellant the right to VA compliance with the terms of the
remand order and imposes on the Secretary a concomitant duty to ensure compliance with those
terms. See Stegall v. West, 11 Vet.App. 268, 271 (1998). A final decision by the Board following


                                                25
the remand herein ordered will constitute a new decision that, if adverse, may be appealed to this
Court only upon the filing of a new NOA with the Court not later than 120 days after the date on
which notice of the new Board final decision is mailed to the appellant. See Marsh v. West,
11 Vet.App. 468, 472 (1998).
       REVERSED AND REMANDED.
