Of The Special Master’s December 1, 2015 Ruling On Redaction Request And Change Of Case

Based on that Opinion, the court has replaced Petitioners’ actual names with initials in this

                                                1
   I.        RELEVANT FACTUAL BACKGROUND.2
       A.K. was born on November 9, 1999 to R.K. and L.K. (collectively, the “Petitioners”). Pet.
Ex. 61 at 2. When A.K. was about 18 months of age, Petitioners became concerned that A.K.’s
speech was delayed. Dec. at 88. On November 2, 2001 and December 3, 2001, A.K. received
influenza vaccinations around his second birthday. Id. at 11. On November 21, 2001, A.K.’s
medical records explicitly noted speech delay during his two year visit. Id. at 89.
        On September 22, 2002, Dr. Marvin Boris, A.K.’s primary pediatrician, indicated that A.K.
might have Autism Spectrum Disorder (“ASD”). Id. at 13. From 2002 to 2003, A.K. was treated
for various gastrointestinal problems. Id. at 14. On April 22, 2004, A.K. was formally diagnosed
with ASD. Id.
      On November 20, 2008, A.K. was diagnosed with “probabl[e] mitochondrial
encephalomyopathy[.]” Pet. Ex. 32 at 3.
   II.       PROCEDURAL HISTORY.

             A. As Part Of The Omnibus Autism Proceedings.

        On March 24, 2003, Petitioners filed a Short-Form Petition for Vaccine Compensation
under the National Childhood Vaccine Injury Act, Pub. L. No. 99-660, 100 Stat. 3755, codified as
amended, 42 U.S.C. §§ 300aa–10 et seq. (the “Vaccine Act”). By filing a Short-Form Petition,
Petitioners opted into the Omnibus Autism Proceeding. Ruling at 2.

       On April 9, 2003, the Special Master issued a Notice Regarding ‘Omnibus Autism
Proceedings’ to stay this case while discovery in the Omnibus Autism Proceeding was conducted.
       On June 23, 2003, the Secretary of Health and Human Services (“the Government”) filed
a Respondent’s Report, stating that the Short-Form Petition “failed to state with particularity the
circumstances surrounding the claim and was not accompanied by materials required[.]” Dkt. No.
4.
        On December 17, 2003, the Special Master issued an Order suspending proceedings for no
longer than 180 days.
        On May 21, 2004, the Special Master issued another Order, stating that “[P]etitioner may
submit a notice in writing choosing to continue or to withdraw the petition . . . and such notice
shall be filed within 30 days[.]” Dkt. No. 8 (internal quotations omitted).
      On June 10, 2004, Petitioners filed a Notice Of Intent To Continue The Petition In Autism
Case. Nothing transpired for almost three years.



         The relevant facts herein were derived from: the Special Master’s September 28, 2015
         2

Decision (“Dec.”), Dkt. No. 320; the September 28, 2015 Ruling On Motions (“Ruling”), Dkt. No.

day, Petitioners filed a Post-Hearing Brief (“Pet. PH.”). In Petitioners’ Post-Hearing Brief, they

                                                 7
requested that Dr. Miller’s testimony “be excluded as evidence[.]” Pet. PH at 34. The Special
Master interpreted Petitioners’ request as a Motion To Strike. Ruling at 48–49. On May 15, 2014,
the Special Master also issued an Order, requiring that the parties file Responses to the opposing
party’s brief by June 16, 2014. On June 16, 2014, the Government and Petitioners filed Responses.
       On September 28, 2015, the Special Master issued a Ruling on Motions and a Decision.
That same day, the case was reassigned to another Special Master.
       On October 13, 2015, Petitioners filed a Motion To Redact The September 28, 2015
Decision. On October 28, 2015, Petitioners filed a Motion For Review and Memorandum In
Support Of The Motion For Review (“Pet. Mem.”). That same day, the case was assigned to Judge
Marian Blank Horn. On October 30, 2015, the Government filed a Response To Petitioners’
October 13, 2015 Motion To Redact. On November 6, 2015, Petitioners filed a Reply To the
Government’s October 30, 2015 Response. That same day, the case was transferred to the
undersigned judge.
        On December 1, 2015, the Special Master issued an Order granting in part and denying in
part Petitioners’ October 13, 2015 Motion To Redact. On December 2, 2015, the Special Master
issued an Order Regarding Redaction Of Material Improperly Filed By Petitioners. On December
3, 2015, the Special Master issued an Order, requiring Petitioners to file copies of documents “with
circles or highlighting the names of the Petitioners, whenever such names are mentioned” within
30 days. Dkt. No. 340.
   III.       DISCUSSION.

              A. Jurisdiction.
       The United States Court of Federal Claims has jurisdiction to review the decision of a
Special Master in a vaccine-related injury case, pursuant to 42 U.S.C. § 300aa–12(e)(2)3 and
Vaccine Rule 23(a).4 After reviewing the Special Master’s decision, the court may:

              (A) uphold the findings of fact and conclusions of law of the special master and
              sustain the special master’s decision,
              (B) set aside any findings of fact or conclusion of law of the special master
              found to be arbitrary, capricious, an abuse of discretion, or otherwise not in
              accordance with law and issue its own findings of fact and conclusions of law,
              or



          Section 300aa-12(e)(2) of the Vaccine Act provides: “[W]ith respect to a petition, the
          3

United States Court of Federal Claims shall have jurisdiction to undertake a review of the record
of the proceedings[.]” 42 U.S.C. § 300aa–12(e)(2).

         Vaccine Rule 23(a) provides: “To obtain review of the [S]pecial [M]aster’s decision, a
          4

party must file a motion for review with the clerk within 30 days after the date the decision is
filed.” Vaccine Rule 23(a).

                                                   8
           (C) remand the petition to the special master for further action in accordance
           with the court’s direction.

42 U.S.C. § 300aa-12(e)(2); see also Vaccine Rule 27 (same).

           B. Standard Of Review.

        The United States Court of Federal Claims may set aside the decision of a Special Master
if findings of fact or conclusions of law are found to be “arbitrary, capricious, an abuse of
discretion, or otherwise not in accordance with law.” 42 U.S.C. § 300aa-12(e)(2)(B). “Fact
findings are reviewed . . . under the arbitrary and capricious standard; legal questions under the
‘not in accordance with law’ standard; and discretionary rulings under the abuse of discretion
standard. The latter will rarely come into play except where the special master excludes evidence.”
Munn v. Sec’y of Dep’t. of Health & Human Servs., 970 F.2d 863, 870 n.10 (Fed. Cir. 1992).

           C. The Elements And Burden Of Proof In Vaccine Act Cases.
         The Vaccine Act provides that a petitioner may receive compensation and other relief under
the Vaccine Injury Compensation Program (“Vaccine Program”), if injury can be established either
by causation in law or causation in fact. Causation in law is established if one of the vaccines
listed in the Vaccine Injury Table at 42 U.S.C. § 300aa-14(a) (“Vaccine Table”) was administered
to a petitioner, and the “first symptom or manifestation of onset or of the significant aggravation
of such injuries, disabilities, illnesses, conditions, and deaths” of specific adverse medical
conditions associated with the use of each vaccine occurred within a time period specified in the
Vaccine Table. See 42 U.S.C. § 300aa-14(a); 42 C.F.R. § 100.3(a). The Vaccine Table is to be
read and interpreted by reference to “Qualifications and aids to interpretation,” that define the key
terms used therein. Id.
         Congress also afforded a petitioner the opportunity to receive relief under the Vaccine
Program, even if the time period for the first symptom or manifestation of a specified injury is not
listed in the Vaccine Table. See 42 U.S.C. § 300aa-11(c)(1)(C)(ii), § 300aa-13. These types of
injuries are known as “off-Table” vaccine injuries. Under these circumstances, a petitioner must
establish causation in fact, by offering sufficient facts to establish each element of a vaccine injury
claim, and meeting the burden of proof as to each element of the claim by a “preponderance of the
evidence” standard. See 42 U.S.C §§ 300aa-13. Accordingly, an off-Table petitioner must proffer
at least some evidence as to each element of the claim and sufficient evidence to persuade the
Special Master or court by a preponderance of evidence. Id.
        In Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317 (Fed. Cir. 2006), the
United States Court of Appeals for the Federal Circuit re-affirmed the three-part test established
in Althen v. Sec’y of Health & Human Servs., 418 F.3d 1274, 1278 (Fed. Cir. 2005) (“Althen”),
for determining causation in fact in off-Table vaccine injury cases. Althen requires a petitioner to:
       show by preponderant evidence that the vaccination brought about [the] injury by
       providing:
       (1)    a medical theory causally connecting the vaccination and the injury;


                                                  9
       (2)     a logical sequence of cause and effect showing that the vaccination was the
       reason for the injury; and
       (3)     a showing of a proximate temporal relationship between vaccination and
       injury.

418 F.3d at 1278.
        If a petitioner is able to establish causation in fact, then the burden of proof shifts to the
Government to establish that a factor unrelated to the vaccine was the actual cause of the
petitioner’s injury. See 42 U.S.C. § 300aa-13(a)(1)(B); see also Althen, 418 F.3d at 1278 (“If [a
petitioner] satisfies this burden, she is entitled to recover unless the [the Government] shows, also
by a preponderance of evidence, that the injury was in fact caused by factors unrelated to the
vaccine.”).
             D. The Special Master’s September 28, 2015 Decision.
        In a 161-page decision, the Special Master addressed three issues: whether the influenza
vaccinations aggravated A.K.’s underlying mitochondrial disorder; whether A.K.’s ASD predated
the influenza vaccinations; and whether Petitioners’ theories of causation met the preponderance
of the evidence standard. Dec. at 9.

       First, the Special Master determined that Petitioners had not sufficiently established that
A.K. had an underlying mitochondrial disorder.5 Dec. at 46. To reach this conclusion, the Special
Master examined the expert evidence the parties provided. Both parties’ experts agreed that there
is much uncertainty in diagnosing mitochondrial disorders and that the field has not yet come to a
consensus on a standardized criteria. Dec. at 49; see also 4/22/2013 TR 249–49 (direct
examination of Dr. Frances Kendall, Petitioners’ expert); see also 4/26/2013 TR 1351 (cross
examination of Dr. Bruce Cohen, the Government’s expert). Nevertheless, Petitioners proffered
two primary pieces of evidence.

       The first piece is a diagnosis from Dr. John Shoffner, who after performing a series of tests
and reviewing the results, diagnosed A.K. with “probabl[e] mitochondrial encephalomyopathy.”

       5
           Mitochondrial disorders occur, because

       the mitochondria cannot efficiently turn sugar and oxygen into energy, so the cells
       do not work correctly. . . . There are many types of mitochondrial disease, and they
       can affect different parts of the body: the brain, kidneys, muscles, heart, eyes, ears,
       and others. . . . They can affect those part(s) mildly or very seriously. Not everyone
       with a mitochondrial disease will show symptoms. However, when discussing the
       group of mitochondrial diseases that tend to affect children, symptoms usually
       appear in the toddler and preschool years. Mitochondrial diseases and disorders are
       the same thing.

Pet. Ex. 32, at 3. The second piece was an expert opinion from Dr. Frances Kendall, who supported
Dr. Shoffner’s diagnosis, concluding that “clinical features and laboratory data collected to date
provide support for a definitive or highly probable mitochondrial disease[.]” Pet. Ex. 65 at 7. Dr.
Kendall used the Bernier criteria, a diagnostic tool used to evaluate mitochondrial disease. Pet.
Ex. 65 at 7; see also Dec. at 49. On cross examination, however, Dr. Kendall admitted that “she
could not reach a definite mitochondrial disorder diagnosis by applying the Bernier criteria.” Dec.
at 50 (citing 4/22/2013 TR 319) (“COUNSEL: So is it still your position that the data and the
clinical features support a definitive or highly probable mitochondrial disease diagnosis? DR.
KENDALL: I would say probably probable . . . with the understanding it’s not definitive.”). Two
of Petitioners’ other experts discussed mitochondrial disorders, but “both indicated that they
deferred to other experts on the diagnosis of mitochondrial disorder.” Dec. at 49 n. 117.

        The Special Master also analyzed Dr. Kendall’s interpretation of the Bernier criteria6
together with three indicators: enzymology results, metabolic indicators, and clinical features.
Dec. at 54. The Special Master found that while enzymology would support a mitochondrial
disorder diagnosis, “A.K.’s results [did] not fall low enough to be considered an abnormal finding
under Bernier[.]” Dec. at 54. With respect to metabolic indicators, Dr. Kendall stated that
“persistent, significant elevations in lactate” indicate mitochondrial disorder. Dec. at 57 (quoting
Pet. Ex. 65, at 5). Dr. Kendall, however, “acknowledged that a single instance of elevated lactic
acid compared to multiple instances of normal findings would not be indicative of persistent,
significant elevation.” Dec. at 58 (citing 4/22/2013 TR 316). With respect to clinical features, the
Special Master did “not see any indication that Dr. Kendall would diagnose a mitochondrial
disorder based on clinical features alone.” Dec. at 63. The Special Master also found that
Petitioners’ experts collectively did “not reflect any independent application of the diagnostic
standards of any interpretive analysis of Dr. Shoffner’s findings.” Dec. at 65.

       Because Petitioner’s primary mitochondrial disorder expert, Dr. Kendall, changed her
opinion on the probability of A.K.’s mitochondrial disorder diagnosis, the Special Master
determined that Petitioners did not establish that A.K. had an underlying mitochondrial disorder.

       Second, the Special Master determined that A.K.’s ASD7 was not temporally related to his
vaccinations, because the Special Master found evidence that A.K.’s ASD symptoms predated the

“of typical symptoms, family history, findings on exam, biochemistry, neuro-imaging and lab
testing.” Amy Goldstein, M.D., Mitochondrial Diseases, CHILD NEUROLOGY FOUNDATION,

          ASD is characterized by:

       Persistent deficits in social communication and social interaction across multiple
       contexts; Restricted, repetitive patterns of behavior, interests, or activities;
       Symptoms must be presented in the early developmental period (typically
       recognized in the first two years of life); and Symptoms cause clinically significant
       impairment in social, occupational, or other important areas of current functioning.

2001 influenza vaccinations. Dec. at 68. Here, the Special Master considered the testimony of
Dr. Judith Miller for the Government and Dr. Yuval Shafrir for Petitioners. Dec. at 68–69.
        Dr. Miller concluded that A.K. demonstrated symptoms of ASD before A.K. received the
influenza vaccinations. Dec. at 77. To reach this conclusion, Dr. Miller relied primarily on
analysis of home videos of A.K. rather than A.K.’s pediatricians’ clinical observations. Dec. at
71–72. This is because “at the time A.K. experienced the onset of his ASD, screening techniques
for one to two year [olds] were not yet available.” Dec. at 71 (citing 4/25/2012 TR 1047–50). Dr.
Miller noted that home videos as far back as January 2001 demonstrated that A.K. had ASD. Dec.
at 77. Specifically, Dr. Miller testified that, in a June 2001 home video, A.K. did not demonstrate
“age appropriate, purposeful play with [a] [baseball] bat.” Dec. at 77. In another video, dated
August 26, 2002, A.K. failed to respond to his name several times, a “big red flag” in terms of
ASD screening. Dec. at 88 (citing 4/25/2012 TR 1008 (cross examination of Dr. Miller)). In a
November 9, 2001 video, A.K. displayed ASD behaviors such as a cognitive inability to recognize
that a wrapped birthday present was for him and seemed more focused on the wrapping paper and
his face did not register any emotional change when the new toy was revealed. Dec. at 75 (citing
4/25/2012 TR 904–07 (direct examination of Dr. Miller)).
         In contrast, Petitioners’ expert, Dr. Shafrir, ended his specialized training in ASD in
2000—well before the developments in the field Dr. Miller described. 4/23/2012 TR 525 (cross
examination of Dr. Shafrir). Dr. Shafrir concluded “that the videos show no signs of ASD prior
to November 10, 2001 and that the November 10 footage shows a dramatic overnight change
compared to footage recorded the day before on November 9, 2001.” Dec. at 73. Dr. Shafrir
testified that the change in A.K.’s behavior between November 9 and 10, 2001 was “the most
dramatic appearance of behavior change I’ve seen in my career.” 4/23/2012 TR 528. The Special
Master, however, noted that “[P]etitioners’ other experts did not appear to find the same
significance in the November 9 and 10 videos.” Dec. at 76. A.K.’s parents also testified that they
did not think A.K.’s behavior change between November 9 and 10 was dramatic. Dec. at 95.
Moreover, one of Petitioners’ own experts who submitted a report, Dr. Mary N. Megson,
corroborated Dr. Miller’s conclusion and contradicted Dr. Shafrir’s. Dec. at 79. Specifically, in
her report, Dr. Megson wrote, “from 16–24 months of age, [A.K.] seem[ed] to plateau in his level
of alertness and processing language.” Pet. Ex. 107, at 6. Dr. Kendall, another of Petitioners’
experts, observed that “A.K. demonstrated speech delay in the videos at 18 months of age[.]” Dec.
at 88.
      Based on this record, the Special Master concluded that “A.K. experienced . . . a gradual
manifestation of ASD which could be observed long before he was administered either of the two
doses of influenza vaccine in . . . 2001.” Dec. at 94–95. In reaching this conclusion, the Special
Master found that “Dr. Miller’s presentation regarding the proper screening and diagnosis for ASD
is not only acceptable, it was in fact far more extensive, better supported, and far more credible
than Dr. Shafrir’s testimony on the same topics.” Dec. at 70.

       Third, the Special Master addressed Petitioners’ theories of causation. Petitioners argued
that “A.K.[‘s] mitochondrial defect renders him particularly susceptible to oxidative stress, which
was activated by the two doses of trivalent influenza vaccine, thereby causing his decompensation
and severe developmental regression.” Pet. PH at 4. To support their argument, Petitioners offered
two different theories of causation.
        First, Dr. Kendall testified that A.K.’s mitochondrial disorder could induce “periods of
decompensation or deterioration[.]” Dec. at 97 (citing Pet. Ex. 65, at 7). The influenza
vaccinations aggravated the mitochondrial disorder, resulting in developmental regression. Dec.
at 97 (citing Pet. Ex. 65, at 8). The Special Master noted, however, that “[t]he evidence that
mitochondrial deterioration can be linked . . . to vaccines is largely anecdotal, and the evidence
that mitochondrial decompensation looks like ASD is nearly non-existent.” Dec. at 97. In
particular, the Special Master criticized Dr. Kendall’s reliance on an article about Poling v. Sec’y
of Health & Human Servs., 2008 WL 1883059 (Fed. Cl. Spec. Mstr. April 10, 2008). Dec. at 101.
The Poling case report studied “a child who regressed after receiving vaccines at 19 months of age
and who was subsequently diagnosed with both ASD and a mitochondrial disorder.” Dec. at 101.
The Special Master surmised that “[t]he Poling case study is merely a single instance . . . . A
single case study in isolation is not significant proof[.]” Dec. at 107. Moreover, the Poling
petitioner’s condition arose after receiving multiple vaccinations—none of which were for
influenza. Dec. at 108–09. The Special Master also critiqued Dr. Kendall’s reliance on a paper
by Dr. Shoffner. Dec. at 110. The Shoffner paper, however, “did not find that a vaccination was
temporally associated with autistic regression in the absence of fever.” Dec. at 103 (citing
4/22/2013 TR 331–32). “[A]bsent an understanding of how or why fever can cause a mitochondrial
deterioration, the conclusions one can draw from . . . the Shoffner article are severely limited[.]”
Dec. at 104.
        Second, Dr. Shafrir posited a “triple hit” hypothesis—that “A.K. had a mitochondrial
disorder, a MTHFR polymorphism, and a genetically-determined abnormal immune system . . .
which . . . combined with his influenza vaccination, caused an autoimmune brain injury
(encephalopathy) which manifested as an autistic regression.” Dec. at 111 (citing Pet. Ex. 63 at
14–18). The Special Master, however, noted that Dr. Shafrir “failed to produce any evidence that
A.K. had a brain injury caused by a vaccine reaction.” Dec. at 132. Moreover, Dr. Shafrir
conceded that “he could not say that A.K.’s MTHFR polymorphisms caused A.K.’s autism[.]”
Dec. at 120.
       Third, Dr. Richard C. Deth testified in support of Dr. Kendall’s and Dr. Shafrir’s theories.
Dr. Deth concluded that “vaccinations promote inflammation and oxidative stress[.]” Dec. at 133
(quoting 4/24/2013 TR 751). The Special Master, however, did not find Dr. Deth to be credible.
Dec. at 133. This is because Dr. Deth “failed to mention that data he was presenting was
potentially contradicted by other findings within the same study.” Dec. at 150.
        Having considered Petitioners’ expert witnesses, the Special Master proceeded to apply the
three-part test articulated in Althen, 418 F.3d at 1278. Dec. at 157. Althen requires a petitioner in
an off-Table causation case to provide: “a medical theory causally connecting the vaccination and
injury; a logical sequence of cause and effect . . . ; and . . . a proximate temporal relationship
between vaccination and injury.” Althen, 418 F.3d at 1278.
      For the first Althen element, the Special Master found that while “‘[m]itochondrial autism’
may someday be accepted as a descriptor for co-morbid autism and mitochondrial disorder
                                                 13
diagnoses . . . there is little evidence that autism itself is caused by such disorder, and no evidence
that autism causes mitochondrial disorders.” Dec. at 157. The Special Master also found that Dr.
Kendall’s theory is “completely unsupported by any scientific literature.” Dec. at 157. Moreover,
Dr. Shafrir “failed to articulate any basis for claiming that an influenza vaccination could lead, via
autoimmunity, to the type of injury A.K. experienced.” Dec. at 157. In addition, the Special
Master found that “Doctor Deth’s opinion suffered far too many serious flaws to be credited.”
Dec. at 158. Here, the Special Master noted that “Dr. Deth acknowledged that not all oxidative
stress is injurious . . . [and] conceded that he could not opine what level of oxidative stress is
created by a vaccination or what level of oxidative stress would be necessary to cause the type of
neurological injury he described.” Dec. at 158.
        For the second and third Althen elements, the Special Master found that there was not a
logical sequence of cause and effect between the vaccination and injury or proximate temporal
connection, because “there is strong evidence in the record suggesting that A.K.’s condition
predated his vaccinations.” Dec. at 158.




           E. Petitioners’ October 28, 2015 Motion For Review.

                    1. Petitioners’ Objections.
       Petitioners’ October 20, 2015 Motion includes a constitutional claim and twelve objections
to the Special Master’s September 28, 2015 Decision that are summarized as follows: 1) the
amendment of the Vaccine Act is unconstitutional; 2) the Special Master’s determination that
A.K.’s ASD predated the influenza vaccinations was arbitrary and capricious; 3) the Special
Master’s determination that A.K. did not have an underlying mitochondrial disorder was arbitrary
and capricious; 4) the Special Master misapplied Althen to Petitioners’ causation theories; 5) the
Special Master improperly denied Petitioners’ Motion For Judicial Estoppel; and 6) the Special
Master improperly denied Petitioners’ Motion To Exclude.
        Petitioners first argue that Congress cannot bar common law litigants from access to Article
III courts. Pet. Mem. at 3 (citing Stern v. Marshall, 131 S. Ct. 2594, 2615 (2011) (“The ‘experts’
in the federal system at resolving common law counterclaims . . . are the Article III courts[.]”).
Because the Vaccine Act denies Petitioners access to an Article III court, the Vaccine Act is
unconstitutional and denies due process of law. Pet. Mem. at 3.
       The Special Master’s determination that A.K.’s ASD predated the influenza vaccinations
also was arbitrary and capricious, because the Special Master credited the Government’s expert
witness, Dr. Miller, over Petitioners’ expert witness, Dr. Boris, who had “a far greater level of
experience than Dr. Miller and had the advantage of treating [A.K.] over a long period of time[.]”
Pet. Mem. at 7–8. Dr. Megson also was more qualified than Dr. Miller, because she is “a
developmental pediatrician with over 40 years’ experience specializing in the treatment of autistic
children, with the added qualification of being the mother of four children, three of whom are
boys[.]” Pet. Mem. at 12. Because the Special Master relied on Dr. Miller instead of Petitioners’


                                                  14
superior expert witnesses, the Special Master’s conclusion was “unsupported by competent
evidence.” Pet. Mem. at 15.
        Next, Petitioners contend that the Special Master’s “conclusion that [A.K.] does not have
mitochondrial disease is one that defies applicable law.” Pet. Mem. at 17. Mitochondrial disorder
diagnosis lacks an objective diagnostic criteria. Pet. Mem. at 19. When “reasonable medical
minds may legitimately differ . . . [the United States Court of Appeals for] [t]he Federal Circuit’s
instruction set forth in Althen, 418 F.3d 1274 (Fed. Cir. 2005) and Capizanno, 440 F.3d 1317,
1325 (Fed. Cir. 2006) . . . is to defer to the petitioners’ experts[.]” Pet. Mem. at 19.
       In addition, the Special Master’s conclusion that Petitioners did not provide a reliable
causation theory was error and the Special Master improperly raised Petitioners’ burden of proof.
Pet. Mem. at 33, 38. In determining that the Petitioners’ experts did not establish how or why a
fever can cause oxidative damage in conjunction with mitochondrial disease, the Special Master
improperly raised the burden of proof to beyond a preponderance of evidence standard. Pet. Mem.
at 39.
        Petitioners add that the Special Master erred in denying Petitioners’ Motion to estop the
Government from denying that a vaccination creates sufficient stress to cause autism in a child
with mitochondrial disorder. Pet. Mem. at 56. Specifically, in Poling, 2008 WL 1883059, the
Government filed a Rule 4 Report, conceding that “the facts of this case meet the statutory criteria
for demonstrating that the vaccination . . . received on July 19, 2000, significantly aggravated an
underlying mitochondrial disorder, which . . . manifested as a regressive encephalopathy with
features of [ASD].” Poling, 2008 WL 1883059, at *1. Therefore, the Government should have
been estopped from arguing otherwise here. Pet. Mem. at 57.
       Finally, the Special Master’s denial of Petitioner’s Motion To Exclude The Testimony Of
Dr. Miller8 was in error. Pet. Mem. at 57.
                    2. The Government’s Response.
        The Government did not respond to Petitioners’ constitutional argument; but defended the
Special Master’s determination that A.K.’s ASD predated the influenza vaccination was not
arbitrary or capricious. Gov’t Mem. at 12. It is within a Special Master’s purview to weigh expert
testimony. Gov’t Mem. at 13 (citing Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315,
1325 (Fed. Cir. 2010) (“Weighing the persuasiveness of particular evidence often requires a finder
of fact to assess the reliability of testimony, including expert testimony, and we have made clear
that the [S]pecial [M]asters have that responsibility in Vaccine Act cases.”). The Special Master’s
decision that Dr. Miller was more credible than Petitioners’ experts is supported by evidence.
Gov’t Mem. at 13. Dr. Miller has more publications on ASD than Petitioners’ experts. Gov’t
Mem. at 13. Dr. Miller also has experience diagnosing ASD, as well as teaching others how to
diagnose ASD. Gov’t Mem. at 13. Moreover, “the Special Master was clear that while she
afforded Dr. Miller’s opinion substantial weight, her determination was based on the totality of
evidence[.]” Gov’t Mem. at 15. “The Special Master also pointed out that two of petitioners’

         Here, Petitioners refer to the Motion To Strike addressed in the Special Master’s Ruling
On Motions. See Ruling, No. 030632V, at 48–49 (considering Petitioners’ argument “that Dr.
Miller’s testimony should be stricken in its entirety” as a “Motion [T]o Strike Dr. Miller’s
Testimony”).
                                                15
experts, Dr. Megson and Dr. Kendall essentially confirmed that A.K. showed symptoms of his
ASD months before vaccinations.” Gov’t Mem. at 15 (citing Dec. at 79, 88).
       The Government argues that the Special Master “did not err in finding that A.K. does not
have a mitochondrial disorder[,]” because the Special Master’s determination is supported by the
record. Gov’t Mem. at 19. The Special Master found Dr. Kendall’s testimony unreliable, because
Dr. Kendall, when cross examined, did not defend her position that A.K. definitively had
mitochondrial dysfunction. Gov’t Mem. at 21. The Special Master evaluated and analyzed the
evidence under the Bernier criteria and is reasoned and factually supported. Gov’t Mem. at 21.
        In addition, Petitioners’ reading of Althen and Capizanno is incorrect. Gov’t Mem. at 23.
The Special Master is not required to defer to any of the experts nor notations in the record. Gov’t
Mem. at 23. Instead, “it was her duty to evaluate the entire evidentiary record, make findings of a
fact, and reach a conclusion . . . in light of the record as a whole.” Gov’t Mem. at 23 (citing Sword
v. Sec’y of Health & Human Servs., 44 Fed. Cl. 183, 188 (1999) (“Expert opinion is just opinion,
and the fact-finder may weigh and assess that opinion in coming to her own conclusions. . . . [T]his
[c]ourt has recognized the unique ability of Special Masters to adjudge cases in light of their own
acquired specialized knowledge and expertise[.]”).
       Likewise, the Special Master’s determination that Petitioners’ causation theories were
unreliable was in accordance with the law. Gov’t Mem. at 24. The Special Master thoroughly
evaluated, but rejected two pieces of evidence on which Dr. Kendall relied to support her causation
theory. Gov’t Mem. at 26. The Special Master also properly rejected the Poling case study and
Dr. Shoffner’s article. Gov’t Mem. at 26. The Special Master’s determination that Petitioners’
expert witness, Dr. Deth, was not credible is “wholly within the Special Master’s charge.” Gov’t
Mem. at 29 (citing Lampe v. Sec’y of Health & Human Servs., 219 F.3d 1357, 1362 (Fed. Cir.
2000) (stating that a Special Master’s “assessments of the credibility of witnesses and the relative
persuasiveness of the competing medical theories of the case . . . are virtually unchallengeable on
appeal[.]”).
        The Special Master also correctly denied Petitioners’ Motion For Estoppel and Motion To
Exclude.9 Gov’t Mot. at 33. In the Ruling On Motions, the Special Master provided four reasons
for rejecting judicial estoppel:
       (1) Judicial estoppel does not apply when a case has been settled; (2) petitioners
       failed to satisfy the three requirements for the invocation of judicial estoppel; (3)
       decisions issued by special masters and judges at the [United States] Court of
       Federal Claims are not binding; and (4) a concession by respondent in one case
       does not constitute a concession in another.
Gov’t Mem. at 33 (citing Ruling at 36–37).



       9
         The Government collectively refers to these motions as a Motion To Strike as addressed
in the Special Master’s Ruling On Motions. See Ruling at 48–49 (interpreting Petitioners’
argument “that Dr. Miller’s testimony should be stricken in its entirety” as a “Motion [T]o Strike
Dr. Miller’s Testimony”).


                                                 16
        With respect to Petitioners’ Motion To Exclude, the Special Master found Dr. Miller
qualified to testify, but “noted that any deficiencies in . . . Dr. Miller’s testimony ‘are more
appropriately addressed in the assignment of weight to her testimony rather than its wholescale
exclusion.’” Gov’t Mem. at 33–34 (quoting Ruling at 54).
                    3. The Court’s Resolution.

                            a. The Constitutional Issue.

         As a threshold matter, the Vaccine Act is constitutional, because the Vaccine Act
categorically does not deny access to Article III courts. In fact, Petitioners may appeal this decision
to the United States Court of Appeals for the Federal Circuit. See 42 U.S.C. § 300aa-12(f) (“[A]ny
petitioner aggrieved by the findings or conclusions of the [United States Court of Federal Claims]
may obtain review of the judgment of the court in the United States Court of Appeals for the
Federal Circuit[.]”). In addition, Petitioners have misread Stern’s holding that Article I bankruptcy
courts do not have jurisdiction over common law claims between private parties. See Stern, 131
S. Ct. at 2614–15 (recognizing that the claim at issue was “one under state common law between
two private parties. . . . The ‘experts’ in the federal system at resolving common law counterclaims
. . . are the Article III courts[.]”). The claims in this case, are alleged against the Government
rather than a private party. Moreover, Stern has been limited by the United States Supreme Court’s
recent decision in Wellness Int’l Network, Ltd. v. Sharif, 135 S. Ct. 1932, 1944 (2015) that held,
“allowing Article I adjudicators to decide claims submitted to them by consent does not offend the
separation of powers so long as Article III courts retain supervisory authority over the process.”

                            b. The Merits.

        As for the Special Master’s causation determination, the first element of Althen requires “a
medical theory causally connecting the vaccination and the injury[.]” Id. at 1278. The Special
Master found that Petitioners did not satisfy the first element in concluding that Dr. Kendall’s
causation theory was “unsupported by any scientific literature.” Dec. at 157. The United States
Court of Appeals for the Federal Circuit has held that requiring general acceptance by the scientific
community or requiring medical literature impermissibly raises the preponderance of the evidence
standard. See Althen, 418 F.3d at 1281 (“[T]he Vaccine Act does not require Althen [the
petitioner] to provide medical documentation of plausibility[.]”).
        The second element requires “a logical sequence of cause and effect showing that the
vaccination was the reason for the injury[.]” Id. at 1278. The third element requires “a proximate
temporal relationship[.]” Id. Here, the Special Master properly determined that Petitioners failed
to establish the second and third elements, because A.K. showed “signs of both ASD and speech
delay well before receiving . . . influenza vaccinations.” Dec. at 158. Therefore, the Special Master
determined that there was not a logical sequence, because “the actual timeline of events do not
support [P]etitioners’ claim of a regression.” Dec. at 158. Although the Special Master misapplied
the first element, the correct application of the second and third elements is dispositive as to
causation.
       The Special Master’s determination that A.K.’s ASD predated the influenza vaccinations
was not arbitrary and capricious. It is clear from the September 28, 2015 Decision that the Special
Master based findings of fact about this issue by weighing the credibility of both parties’ experts,

                                                  17
analyzing medical records and related evidence, and personally viewing the home videos of A.K.
Dec. at 68–96.

      Likewise, the Special Master’s determination that A.K. did not have an underlying
mitochondrial disorder is not arbitrary and capricious, because as the fact-finder, the Special
Master may assess “the credibility of the witnesses and the relative persuasiveness of the
competing medical theories of the case.” Lampe, 219 F.3d at 1362.

        As to this issue, Petitioners had the burden to establish that A.K. had a mitochondrial
disorder, but as the Special Master’s decision states, did not meet a preponderance of evidence
standard. See Althen, 418 F.3d at 1278 (“[Petitioner] sought redress . . . for off-Table injury.
[Petitioner] must prove by a preponderance of the evidence that the [] vaccination caused her
malady.”); see also Capizanno, 440 F.3d at 1320 (“In [an off-Table injury] case, the petitioner
must prove by a preponderance of the evidence that the vaccine at issue caused the injury.”). In
this case, the Special Master carefully considered the testimony of Petitioners’ expert, Dr. Kendall.
Dec. at 49. In addition, the Special Master took into consideration that, on cross examination, Dr.
Kendall contradicted her report by conceding that she could not conclude that A.K. definitively
had mitochondrial disorder. 4/22/2013 TR 319. The Special Master also examined A.K.’s lab
results and medical literature proffered. Dec. at 54–68. Therefore, the Special Master “considered
the relevant evidence of record, [drew] plausible inferences, and articulated a rational basis for the
decision.” Lampe, 219 F. 3d at 1360 (internal quotations omitted). As such, it is not for the court
“to reweigh the factual evidence, or to assess whether the [S]pecial [M]aster correctly evaluated
the evidence. And of course we do not examine the probative value of the evidence or the
credibility of the witnesses. These are all matters within the purview of the fact finder.” Munn,
970 F.2d at 871.
                            c. Judicial Estoppel.
      Judicial estoppel “generally prevents a party from prevailing in one phase of a case on an
argument and then relying on a contradictory argument to prevail in another phase.” New
Hampshire v. Maine, 532 U.S. 742, 749 (2001) (internal quotations omitted). Three factors inform
whether judicial estoppel applies:
       [A] party’s later position must be ‘clearly inconsistent’ with its earlier position
       . . . . Second, courts regularly inquire whether the party has succeeded in persuading
       a court to accept that party’s earlier position . . . . Absent success in a prior
       proceeding, a party’s later inconsistent position introduces no ‘risk of inconsistent
       court determinations. . . . A third consideration is whether the party seeking to
       assert an inconsistent position would derive an unfair advantage[.]
Id. at 750–51 (internal citations omitted).
        In the September 28, 2015 Ruling On Motions, the Special Master applied the New
Hampshire factors in denying Petitioners’ Motion For Judicial Estoppel. First, the Special Master
determined that the Government’s position in this case was “not ‘clearly inconsistent’” with its
position in Poling. Ruling at 36. “In Poling, [the Government’s] position was that the child had
sustained a Table injury . . . and thus presumptively should be compensated. Here, there is no
allegation that A.K. suffered a Table injury within the requisite time period.” Ruling at 36. The
Special Master also determined that there was no risk of inconsistent court determinations, because
                                                 18
“Special [M]asters are neither bound by their own decisions nor by cases from the [United States]
Court of Federal Claims, except, of course, in the same case on remand.” Ruling at 36. Finally,
the Special Master determined that Petitioners were not at an unfair disadvantage, because the
Government’s position in Poling and this case are not inconsistent. Ruling at 37.
       Specifically, in Poling, the “vaccinations Hannah received on July 19, 2000, significantly
aggravated an underlying mitochondrial disorder, which predisposed her to deficits in cellular
energy metabolism, and manifested as a regressive encephalopathy with features of [ASD].” Rule
4(c) Report at 7, Poling ex rel. Poling v. Sec'y of Health & Human Servs., No. 02-1466 V, 2008
WL 1883059 (Fed. Cl. Spec. Mstr. Apr. 10, 2008). The vaccinations at issue there were DTaP,
Hib, MMR, Varivax, and IPV. Rule 4(c) Report at 2, Poling ex rel. Poling v. Sec'y of Health &
Human Servs., No. 02-1466 V, 2008 WL 1883059 (Fed. Cl. Spec. Mstr. Apr. 10, 2008). But the
vaccinations in this case are influenza vaccinations. As such, the Government did not assert an
inconsistent position that triggers judicial estoppel.
                            d. Abuse Of Discretion.
        With respect to the Special Master’s denial of Petitioner’s Motion To Exclude Dr. Miller’s
Testimony, the court applies an abuse of discretion standard. See Munn, 970 F.2d at 870 n.10
(“[D]iscretionary rulings [are reviewed] under the abuse of discretion standard. The latter will
rarely come into play except where the [S]pecial [M]aster excludes evidence.”). To find an abuse
of discretion, the court must determine that the Special Master’s decision was “(1) . . . clearly
unreasonable, arbitrary, or fanciful; (2) . . . based on an erroneous conclusion of the law; (3) . . .
clearly erroneous; or (4) the record contains no evidence on which the . . . [Special Master]
rationally could have based his decision.” Hendler v. United States, 952 F.2d 1364, 1380 (Fed.
Cir. 1991). An abuse of discretion generally does not occur where a Special Master “considered
the relevant evidence, drew plausible inferences, and articulated a rational basis for his finding[.]”
Masias v. Sec’y of Health & Human Servs., 634 F.3d 1283, 1290 (Fed. Cir. 2011).

        The Special Master in this case considered Dr. Miller’s experience at the Children’s
Hospital of Philadelphia in the Center for Autism Research. 4/25/2013 TR 847. The Special
Master also considered the Government’s other witness, Dr. Bruce Cohen, who corroborated Dr.
Miller’s testimony. Ruling at 54. In addition, the Special Master found that Dr. Miller had “more
publications on the topic of ASD than any of [P]etitioners’ own experts.” Ruling at 54. Therefore,
since the Special Master’s decision was supported, there was no abuse of discretion.

   IV.     CONCLUSION.

      For the reasons discussed, the court denies Petitioners’ October 28, 2015 Motion For
Review. The Clerk of the Court is directed to enter judgment accordingly.

IT IS SO ORDERED.
