TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN






NO. 03-01-00081-CV



Calvin R. Langford, Appellant

v.


Employees Retirement System of Texas, Appellee





FROM THE DISTRICT COURT OF TRAVIS COUNTY, 345TH JUDICIAL DISTRICT

NO. GN002512, HONORABLE MARGARET A. COOPER, JUDGE PRESIDING





	This case raises similar issues and is controlled by our recent decision in Flores v.
Employees Retirement System, No. 03-01-00074-CV, 2002 Tex. App. LEXIS 2721 (Austin Apr. 18,
2002, no pet. h.).  Where appropriate, we will rely on our reasoning and holdings in that opinion. 
Tex. R. App. P. 47.1.
	Appellant Calvin Langford appeals the district court's judgment affirming a final
order by the Board of the Employees Retirement System of Texas (hereinafter "the Board") denying
his application for occupational disability benefits. (1)  Mr. Langford raises the same issues that were
raised in Flores: whether the Board acted arbitrarily and capriciously or abused its discretion by 
applying a new policy in the course of his contested case without affording him notice of its intent
to do so, and whether the Board erroneously interpreted the statutory definition of occupational
disability.  Additionally, he complains about the trial judge's ruling denying his request to
supplement the administrative record.  As we sustain two of Mr. Langford's issues, we will reverse
the judgment of the trial court.

FACTUAL BACKGROUND

	Calvin Langford was employed by the Texas Department of Criminal Justice as a
food service manager at one of its correctional facilities.  Mr. Langford's position required him to
supervise food service workers, including inmates and employees, in the preparation and storage of
food and in the inspection and maintenance of the kitchen facility in a sanitary and safe manner. 
Departmental policy required the kitchen floor to be cleaned at least once each day.  As he
approached an inmate who was mopping the floor to tell him to put a "Wet Floor" sign out, Mr.
Langford slipped and fell on the wet kitchen floor.  The inmate had failed to use the appropriate
cleaner, using instead a highly concentrated dishwashing detergent which, when applied to the floor,
made it extremely slick.  Mr. Langford testified that even though he was wearing skid-resistant
shoes, he fell, catching his leg on a cooking grill and landing in an awkward position.  Mr. Langford
sustained serious injury to his back and is permanently disabled.  He was dismissed from his job
several months after the accident.
	After his dismissal, Mr. Langford applied for disability retirement benefits from the
Employees Retirement System ("ERS"), (2) which was created by the legislature for the purpose of
providing a retirement system for "aged and incapacitated state employees."  Act of 1947, 50th Leg.,
R.S., ch. 352, 1947 Gen. Laws 697, 697 (statement of purpose).  Mr. Langford applied for
occupational disability retirement benefits (3) and was certified by the Medical Board as permanently
incapacitated from the further performance of his duties.  His application was denied, however,
because the Board found that his disability did not meet the statutory criteria for occupational
disability retirement benefits.
	The criteria are found in section 811.001(12) of the Government Code, which defines
occupational disability to mean a disability "from an injury or disease that directly results from a
specific act or occurrence determinable by a definite time and place, and directly results from a risk
or a hazard peculiar to and inherent in a duty that arises from and in the course of state employment." 
Tex. Gov't Code Ann. § 811.001(12) (West Supp. 2002). (4)  ERS denied Mr. Langford's claim,
finding that his disability failed to satisfy either statutory prong of the definition.  He appealed, and
after an administrative hearing, the administrative law judge (ALJ) found that Mr. Langford's
application satisfied both requirements and recommended in his proposal for decision (PFD) that
occupational disability benefits be awarded.  The Board rejected the ALJ's findings of fact and
conclusions of law (5) as to both statutory prongs and denied benefits.  The Board's interpretation of
the statutory definition for disability benefits in this appeal is identical to the definitions it adopted
in the Flores appeal.  We have held that the Board erroneously interpreted both prongs of the statute. 
Flores, No. 03-01-00074-CV, slip op. at 33, 2002 Tex. App. LEXIS 2721, at *54-55 .  Mr. Langford
has also challenged the manner in which the Board decided his appeal, contending that the Board
violated his substantial rights by failing to provide him with a meaningful hearing as required by the
Administrative Procedure Act (APA).  For the same reasons that we explained in Flores, we hold
that the Board's decision-making process was arbitrary and capricious and an abuse of discretion. 
As a preliminary matter, we turn first to an issue raised by Mr. Langford regarding additional
evidence.

 ADDITIONAL EVIDENCE
	Mr. Langford argues in his first issue that the trial court erred by refusing to admit
into evidence a resolution that the Board adopted after the ALJ submitted his PFD and before the
Board issued its order rejecting the ALJ's decision and denying the application for benefits.  Mr.
Langford cites section 2001.175(c) of the Government Code in support of his argument that the trial
court should have admitted the resolution, despite the fact that it was not part of the administrative
record.  See Tex. Gov't Code Ann. § 2001.175(c) (West 2000).  The provision reads:

A party may apply to the court to present additional evidence.  If the court is satisfied
that the additional evidence is material and that there were good reasons for the
failure to present it in the proceeding before the state agency, the court may order that
the additional evidence be taken before the agency on conditions determined by the
court.  The agency may change its findings and decision by reason of the additional
evidence and shall file the additional evidence and any changes, new findings, or
decisions with the reviewing court.

Id.
	We review the district court's decision to grant or deny a remand request under an
abuse of discretion standard.  Gulf States Utils. Co. v. Coalition of Cities for Affordable Util. Rates,
883 S.W.2d 739, 747-48 (Tex. App.--Austin 1994, no writ).  Section 2001.175(c) enables the
district court to remand the case to the agency for the admission of the additional evidence.  Texas
Oil & Gas Corp. v. Railroad Comm'n, 575 S.W.2d 348, 351 (Tex. Civ. App.--Austin 1978, no writ)
(discussing virtually identical predecessor version of section 2001.175(c)).  Mr. Langford, however,
argues that the district court erred by not admitting the evidence for consideration in connection with
the district-court case.  Mr. Langford misunderstands the purpose of section 2001.175(c), which is 
to give a party the opportunity to present additional evidence to the agency for its consideration; it
is not intended to enable a party to present evidence before a reviewing court.  We also note that the
resolution does not constitute "additional evidence" as contemplated by section 2001.175(c); if
anything, the resolution may constitute evidence of "procedural irregularities alleged to have
occurred before the agency that are not reflected in the record."  See Tex. Gov't Code Ann.
§ 2001.175(e).  Mr. Langford does not rely on section 2001.175(e), however, and in any event, the
resolution is already before us and is included in the record; additionally, a large portion of the
resolution is quoted verbatim in the Board's conclusions of law.  Therefore, we overrule Mr.
Langford's first issue.  We now turn to his argument that the Board acted arbitrarily and capriciously
in denying his appeal.

ARBITRARY & CAPRICIOUS
	In his second issue, Mr. Langford raises the same issues regarding the Board's manner
of decision-making as were raised in Flores and asserts that the Board's action was arbitrary and
capricious or constituted an abuse of discretion under section 2001.174(2)(F) of the APA.  See Tex.
Gov't Code Ann. § 2001.174(2)(F) (West 2000). (6)  As in Flores, the manner in which the Board
decided this appeal raises serious concerns as to whether the Board respected Mr. Langford's due-
process rights.  A brief recitation of the facts highlights these concerns.  After hearing all of the
evidence at the contested-case hearing on September 30, 1999, the ALJ decided in Mr. Langford's
favor on October 28.  The Board adopted new policies in a resolution on December 8.  This same
resolution limited the viability of some of the Board's previous decisions on which Mr. Langford
had relied at the hearing.  The Board met to consider Mr. Langford's appeal on April 19, 2000.  The
minutes of that meeting, of which we take judicial notice, reflect that immediately after hearing from
both sides and without any deliberation, the Board declined to adopt the ALJ's recommendation and
denied Mr. Langford's appeal.  After announcing its decision, the Board also ordered its general
counsel to make new findings of fact and conclusions of law.  The revised findings of fact and
conclusions of law, which were later adopted by the Board, relied on the new policies announced in
the post-hearing resolution.
	Moreover, the Board's findings of fact and conclusions of law made systematic and
widespread changes and additions to the ALJ's findings of fact and conclusions of law.  The Board's
changes to particular facts suggest that the Board was acting as its own fact finder despite having
delegated that duty to the ALJ.  See Montgomery Indep. Sch. Dist. v. Davis, 34 S.W.3d 559, 564
(Tex. 2000) ("[h]aving chosen to delegate the fact-finding role to the hearing examiner, a board
cannot then ignore those findings with which it disagrees and substitute its own additional
findings"); Flores, No. 03-01-00074-CV, slip op. at 7-8, at *8-9.  In addition, in some instances, the
Board failed to comply with its statute and administrative rules, which authorize the Board to make
changes but also place limits on its ability to do so.  See Tex. Gov't Code Ann. § 815.511(a) (West
Supp. 2002); 34 Tex. Admin. Code § 67.91(b) (2001) (Rule 67.91(b). (7)
	The manner by which the Board decided Mr. Langford's appeal raises serious due
process concerns, specifically in its (1) failing to put Mr. Langford on notice as to the grounds on
which the Board would rely for its decision; (2) arriving at a result on grounds other than those
presented at the hearing; (3) making its decision first and then making findings of fact to support that
new result; (4) failing to adequately explain its departure from prior decisions; and (5) failing to
comply with its statute and rule regarding changes to an ALJ's findings of fact and conclusions of
law.  These issues have been discussed at length in Flores and we need not address each one
individually.  We reiterate that an agency must respect the due process rights of applicants who
appear before it in contested cases.  See Flores, No. 03-01-00074-CV, slip op. at 6, at *9.  We
sustain Mr. Langford's second issue.

STATUTORY DEFINITION OF OCCUPATIONAL DISABILITY
	In his third issue, Mr. Langford challenges the Board's statutory definition of
occupational disability. (8)  We turn now to the first prong of that definition.

"Directly Results from a Specific Act or Occurrence"
 At issue in this appeal, as in Flores, is the causal relationship that must be established
between the traumatic incident (a specific act or occurrence determinable by a definite time and
place) and resulting disability when the claimant also has preexisting conditions that contribute to
the disability.  In Flores, we affirmed the Board's conclusion that the employee must prove that the
at-work injury is the primary cause of his disability.  Flores, No. 03-01-00074-CV, slip op. at 26-7,
at *44-45.  But we disapproved the Board's additional rule that an employee must establish that an
occupational trauma is the direct cause of his disability "without regard to a preexisting mental or
physical condition."  We noted that a traumatic injury often interacts with other factors to produce
a disability and the plain language of the statute does not mandate that the disability claimant be free
from all preexisting conditions, including age-related back degeneration.  It does mandate, however,
that when there are preexisting mental or physical conditions, the claimant must establish that the
traumatic incident is the primary cause of the disability.  On the other hand, if the medical evidence
establishes that a preexisting condition is the primary cause of incapacity, the disability does not
directly result from a specific act or occurrence determinable by a definite time and place.
	The Board rejected the ALJ's conclusion that Mr. Langford's disability resulted from
a specific occurrence determinable by a definite time and place, saying that the ALJ had
misinterpreted and failed to apply the policy of the Board regarding preexisting conditions.  The
Board's explanation for rejecting the ALJ's conclusion stated that in accordance with its policy and
its interpretation of the statute, "a member has been required to present credible medical evidence
that a specific occupational trauma is the direct cause of the member's disability without regard to
a preexisting mental or physical condition."  (Employees Ret. Sys. of Tex., Appeal of Calvin
Langford's Application for Occupational Disability Benefits, Docket No. XXX-XX-XXXX (June 14,
2000) (order adopting proposed findings of fact and conclusion of law and denying application for
benefit) (emphasis added)).  The Board further explained that the ALJ, by relying on the Board's
earlier decisions that an age-related preexisting condition would not disqualify an applicant,
impermissibly expanded the statutory definition of an occupational disability.
	Under the definition announced in Flores, the Board could reject the  ALJ's
conclusion that Mr. Langford's disability directly resulted from a specific act or occurrence
determinable by a definite time and place only if it concluded, and the evidence supported a
conclusion, that his disability was primarily caused by a preexisting condition.

The Medical Evidence
	Mr. Langford's treating physician, Dr. Jerjis J. Denno, diagnosed him as having a
lumbar herniated nucleus pulposus (9) with lumbar spinal stenosis. (10)  Mr. Langford had preexisting
degenerative conditions in his spine caused by the aging process, but these were mild to moderate
in nature.  In response to a deposition question inquiring as to any and all preexisting conditions, Dr.
Denno indicated that Mr. Langford had "lumbar spondylosis with bulging discs,"  "ligamentum
hypertrophy, facet hypertrophy," and "spinal stenosis" and that the spondylosis and spinal stenosis
at the L4-5 vertebrae could make the herniated disc at L4-5 more symptomatic.  Dr. Denno also
noted that such degenerative conditions were normal for a man of Mr. Langford's age (he was fifty-one at the time of his fall) and were part of a "normal progressive condition (wear and tear of the
spine)."  Dr. Denno further wrote in his notes after an office visit by Mr. Langford:

I explained to Mr. Langford that degeneration in the spine was a preexisting
condition.  I do feel that the herniated disc in his lumbar spine at L4-5 was a direct
result of the work-related injury of August 17, 1998.  Degeneration of lumbar discs
is a fairly common finding in the adult population.  It is usually asymptomatic and
does not necessarily lead to a herniation.  It was Mr. Langford's fall at work that led
to the herniation of the disc in his lumbar spine. 


(Emphasis added.)
 Similarly, in his response to a deposition question that asked whether Mr. Langford's
preexisting conditions caused his injuries following the slip-and-fall, Dr. Denno answered: "No, the
preexisting condition was aggravated by the work injury."  Dr. Denno also stated that these
preexisting conditions would not have prevented Mr. Langford from performing the normal duties
of his job prior to the accident.  Moreover, Dr. Denno found that the workplace accident would
probably have been sufficient to permanently disable Mr. Langford even in the absence of the
preexisting condition.  Had the accident not occurred, Dr. Denno expected that Mr. Langford
probably would have been able to continue in his job until he reached sixty-five years of age. 
 While the ERS staff disputed the causal relationship between Mr. Langford's accident
and his disability, it failed to present any evidence that would have controverted the evidence offered
by Mr. Langford.  The staff presented the statement by the Medical Board in its certification of Mr.
Langford's disability that Mr. Langford's injury probably would not have been permanently disabling
in the absence of the preexisting conditions.  The Medical Board did not refer to the evidence on
which it was basing its conclusion, nor do we find any evidence in the record that supports such a
conclusion.  The ALJ found that Mr Langford's spinal degeneration contributed to his permanent
incapacity in that it made the traumatic injury more symptomatic and less treatable; the ALJ also
found that the degeneration was caused only by the natural-aging process.  Moreover, there is no
finding that Mr. Langford's preexisting condition primarily caused his disability.  Indeed, the
medical evidence in the record indicates that Mr. Langford's preexisting spinal condition was mild
to moderate. 
	The ERS staff also pointed to the opinion of the Medical Board that Mr. Langford's
obesity played a role in causing his disability.  Although the Medical Board included "morbid
obesity" among the causes of Mr. Langford's incapacity, it did not refer to any specific evidence
supporting the causal relationship between his weight and his disability.  Moreover, in response to
a specific question on the certification form inquiring as to whether the traumatic incident aggravated
a preexisting condition, the Medical Board referred only to the degenerative disc condition.  While
there is a reference to Mr. Langford's obesity in his medical records, there is no indication that Mr.
Langford's weight was a factor in causing his incapacity.  Mr. Langford's weight, then, could not
have been the "primary cause" of his disability.
	The ALJ weighed the evidence presented by Mr. Langford, which included the
testimony of his treating physician, against the conclusory statements offered by the agency.  The
ALJ specifically took note of this disparity in the evidence in his proposed decision:

The ERS Medical Board found that Mr. Langford's incapacity was caused by
"herniated lumbar disc, spinal stenosis, morbid obesity" and that "disc injury" and
spinal "degenerative disease" were preexisting at the time of Mr. Langford's slip and
fall.  The nature and extent of analysis performed by the board in reaching these
conclusions (which were set out in the [medical] board's formal certification on Mr.
Langford's application) is [sic] not indicated in the record.

On the other hand, Mr. Langford's treating physician, Jerjis J. Denno, M.D., an
orthopedic surgeon, testified by written deposition that the immediate cause of Mr.
Langford's disability--i.e., a herniated disc at the L4-5 level--resulted directly from
the incident on August 17, 1998, and would have occurred even in the absence of
preexisting conditions.  Dr. Denno acknowledged that his patient exhibited
degenerative conditions that predated the accident-including lumbar spondylosis with
bulging discs, ligamentum hypertrophy, and facet hypertrophy at L2-3, L3-4, L4-5,
and L5-S1 levels.  However, while these preexisting conditions made Mr. Langford's
herniated disc at L4-5 more symptomatic and difficult to treat than would otherwise
have been the case, they did not directly cause the patient's disabling injury and, by
themselves, would not have prevented him from undertaking his normal job activities.


(Emphasis added.)
 On appeal, the Board found that the ALJ's conclusion that Mr. Langford's disability
directly resulted from a specific act or occurrence determinable by a definite time and place
"erroneously expands the definition of occupational disability to include a disability that is primarily
caused by degeneration that is the result of the natural-aging process." (11)  We are unable to find the
evidence that would support this conclusion.  In fact, the only evidence in the record reflects that Mr.
Langford was fully capable of performing his job duties prior to the traumatic slip-and-fall injury but
was disabled after the injury.
	The Board rejected the ALJ's conclusion of law that Mr. Langford's injury directly
resulted from a specific act or occurrence determinable by a definite time and place.  We hold that
in rejecting this conclusion the Board erred first, because it erroneously applied its without-regard-to-preexisting-conditions rule that disqualified Mr. Langford because he had an asymptomatic back
condition that was aggravated by his fall, and second, because it substituted its conclusion that Mr.
Langford's disability was primarily caused by his degenerative back disease, when the evidence does
not support such a conclusion.  We hold that the Board applied an erroneous interpretation of the
statute in rejecting the ALJ's conclusion that Mr. Langford's disability directly resulted from a
specific act or occurrence determinable by a definite time and place.

"RISK OR HAZARD PECULIAR TO A DUTY"
 The Board rejected the ALJ's conclusion that Mr. Langford's disability directly
resulted from a risk or hazard peculiar to his duties of state employment on the ground that it was
"based on a misunderstanding or misinterpretation of Board policy, specifically, that the risk of
slipping and falling is a common risk not peculiar to duties that arise from and in the course of state
employment." (12)  We have held that the Board's interpretation of this prong of the statute is
inconsistent both with the statute and with our decision in Bond v. Employees Retirement System,
825 S.W.2d 804 (Tex. App.--Austin 1992, writ denied).  See Flores, No. 03-01-00074-CV, slip op.
at 32, at *52.  In Flores, we rejected the Board's position that for a risk or hazard to be peculiar to
a duty of state employment, the duty must impose a risk or hazard that is somehow different from
the risk assumed by other persons engaged in the same activity.  Id. at 31, at *52.  We clarified that
a risk or hazard is peculiar to a duty if that duty imposes a risk or hazard different from the normal
or usual risks encountered by a person not engaged in that duty.  Id. at 31-2, at *52.  Under the
standard announced in Flores, the Board erred by rejecting the ALJ's conclusion that Mr. Langford's
disability directly resulted from a risk or a hazard peculiar to his duties.
	Mr. Langford was injured while performing his duties in the food service area of the
Department of Criminal Justice where he was employed.  The Department's training manual
addresses the need for sanitation in this institutional dining area: the floors are to be scrubbed with
soap or other chemicals as often as necessary, at least daily. (13)  Recognizing that frequent cleaning
would enhance the hazard of slippery floors, the Department's manual specifically instructs 
employees regarding the prevention of "slips, trips, and falls": "Avoid excessive water when
cleaning floors; [b]e very careful when walking in the Food Service department, floors may be wet
and slippery; [c]lean up spills immediately; [k]eep walkways clean, clear and free of debris; [w]alk
safely."  The manual also requires that "wet floor" signs be posted immediately after cleaning and
recommends that both employees and inmates working in the food service area wear non-skid shoes,
such as rubber boots.
	All employee and inmate workers in the facility had to be careful to avoid the frequent
risk posed by wet floors.  As a manager who supervised compliance with sanitation and safety
requirements, however, Mr. Langford routinely had to put himself in harm's way by walking into
wet areas to perform his duties. (14)  At the hearing, he testified that he had developed a way of walking
through the kitchen and dining facility by taking cautious "half-steps" to protect himself.  When he
slipped and fell, Mr. Langford was wearing skid-resistant shoes and walking with this half-step gait
toward the inmate on duty to tell him to post a "wet floor" sign.  Thus, Mr. Langford's accident was
precisely related to his unique duties as a food-service manager in the facility.  We hold that there
is abundant evidence in the record that the risk of falling on slippery floors was peculiar to Mr.
Langford's employment duties.  The risk of falling imposed by his duties as a food service manager
working on constantly wet floors is different from the normal or usual risk of slipping and falling. 
The ALJ so found in his findings of facts and in his PFD.  We hold that the Board applied an
erroneous interpretation of the statute in reversing the ALJ's conclusion of law that Mr. Langford's
injury directly resulted from an inherent risk or hazard peculiar to a duty arising from his state
employment.
	We sustain the third issue on appeal and hold that the Board applied an erroneous 
interpretation of both prongs of the statute in deciding Mr. Langford's appeal. 

CONCLUSION
 We hold that the Board acted arbitrarily and capriciously for the same reasons
outlined in Flores, most notably by its disregard for the ALJ's determination of the adjudicative
facts.  For the reasons set out in our opinion in Flores, we hold that the Board applied an erroneous
interpretation of the statute in rejecting the ALJ's conclusions of law as to both prongs of the
definition of occupational disability.  Therefore, we reverse the district court's judgment and the
Board's order and remand this cause to the Board for further proceedings consistent with this
opinion.

The requirements of Mr. Langford's roving supervisory position, however,
appear to have made him especially exposed to [the hazard of slippery floors]. 
In the process of monitoring the performance of food service workers
(including, specifically, their compliance with sanitation and safety
regulations), he was obliged to traverse frequently all parts of the large food
preparation area.  With the mopping up of random spills and the prescribed
minimum daily scrubbing of all floors, Mr. Langford must have had to
negotiate a constantly changing geography of slippery surfaces.  But his job
entailed not just the avoidance of these numerous and shifting wet areas; it
often required him to move deliberately into such areas, as he did when he was
injured, to assure that clean-ups were performed both effectively and with
proper precautions.  The difficulty of this task was undoubtedly increased by
the inattentive, if not refractory, attitudes of some of the inmate workers-a
circumstance that clearly contributed to the accident on August 17, 1998.
