       Per Curiam.
       {¶ 1} Appellee Industrial Commission of Ohio granted the request of
appellee Gary E. Bisdorf for permanent-total-disability (“PTD”) compensation.
The Tenth District Court of Appeals denied the request of Bisdorf’s former
employer, appellant, Navistar, Inc., for a writ of mandamus ordering the
commission to vacate the PTD-compensation award.           Navistar appealed that
judgment and moved for oral argument. During the pendency of the case before
this court, Bisdorf died. We ordered Navistar to show cause why its appeal should
not be dismissed as moot. Navistar responded with a motion to continue (i.e.,
proceed with) the case, which we grant. We affirm the Tenth District’s judgment
and deny Navistar’s request for oral argument.
                  I. FACTS AND PROCEDURAL HISTORY
       {¶ 2} Bisdorf sustained two industrial injuries during his 30 years of
employment as an assembler with Navistar. His 1971 knee injury and 2001
shoulder injury both resulted in approved workers’ compensation claims and
multiple surgeries. Bisdorf retired from Navistar in 2003 but worked part-time as
a sales associate and firearms instructor at a gun store from 2004 to 2010.
       {¶ 3} During his employment at the gun store, Bisdorf applied for a period
of temporary-total-disability (“TTD”) compensation for knee surgery related to his
1971 injury. The commission determined that Bisdorf had voluntarily retired from
Navistar but had rejoined the workforce by accepting employment at the gun store,
and it granted his request for TTD compensation. Bisdorf returned to work, but the
gun store closed in 2010, and he did not seek new employment.
       {¶ 4} In 2015, Bisdorf applied for PTD compensation. After a hearing
before a staff hearing officer (“SHO”), the commission granted Bisdorf’s
application. Navistar moved for reconsideration, arguing that the commission had
failed to consider evidence of Bisdorf’s voluntary retirement and that the
commission had relied on two medical reports—by Drs. James Rutherford and



                                         2
                               January Term, 2020




David Grunstein—that Navistar claimed were conclusory and contradictory. The
commission denied Navistar’s request for reconsideration.
       {¶ 5} Navistar asked the Tenth District for a writ of mandamus ordering the
commission to vacate its prior orders and to enter a new order denying Bisdorf’s
PTD-compensation application. Navistar asserted that the commission had abused
its discretion in numerous ways, including by awarding PTD compensation without
first ruling on whether Bisdorf had voluntarily abandoned his employment and by
relying on the reports by Drs. Rutherford and Grunstein.
       {¶ 6} The Tenth District’s magistrate initially recommended that the court
grant a limited writ ordering the commission to consider whether Bisdorf had
voluntarily abandoned his employment. 2017-Ohio-8976, ¶ 2. But the court
sustained the commission’s objections to the magistrate’s recommendation and
held that Navistar had failed to raise the issue of voluntary abandonment before the
SHO. Id. at ¶ 20-24. The court therefore returned the case to the magistrate to
consider the remaining issues that Navistar had asserted. Id. at ¶ 29. After doing
so, the magistrate recommended that the court deny the writ. 2018-Ohio-3386, ¶ 3.
Navistar objected, but the court overruled Navistar’s objections and adopted the
magistrate’s recommendation. Id. at ¶ 10. Navistar appealed the Tenth District’s
judgment to this court and moved for oral argument.
       {¶ 7} On July 30, 2019, after briefing in this court was complete, Bisdorf’s
counsel filed a suggestion of death indicating that Bisdorf had died on July 8. We
ordered Navistar to show cause why the case should not be dismissed as moot, and
we permitted appellees to respond to Navistar’s filing. 156 Ohio St.3d 1491, 2019-
Ohio-3263, 129 N.E.3d 474. In response to the show-cause order, Navistar filed a
motion to continue (i.e., proceed with) the case. The Industrial Commission and
counsel for Bisdorf filed responses to Navistar’s motion.

                                  II. ANALYSIS
                   A. State of the Case After Bisdorf’s Death
       {¶ 8} Navistar asserts two reasons why we should proceed to decide the
case. First, citing Youghiogheny & Ohio Coal Co. v. Mayfield, 11 Ohio St.3d 70,
464 N.E.2d 133 (1984), it argues that an employer’s appeal from an adverse
decision by the commission is not subject to dismissal due to a claimant’s death.
Second, without citing any authority, it argues that “the case should continue due
to the precedential value of the two issues to be determined.” The second argument
is without merit. As the commission notes in its response, we do not issue advisory
opinions. See, e.g., State ex rel. Food & Water Watch v. State, 153 Ohio St.3d 1,
2018-Ohio-555, 100 N.E.3d 391, ¶ 29.
       {¶ 9} As to the first argument, while an injured worker’s claim for benefits
abates upon his death, Ohio Adm.Code 4123-5-21, this court held in Youghiogheny
that “[a]n employer’s appeal, pursuant to R.C. 4123.519, from an adverse ruling by
the Industrial Commission is not subject to dismissal due to the death of the
employee during the pendency of the appeal,” id. at syllabus. In reaching this
conclusion, this court reasoned that under former R.C. 4123.519, the employer was
entitled to recover from the state surplus fund any benefits that had been improperly
disbursed to the claimant before his death. Id. at 72. The state (which was already
a party to the proceedings in the form of the Administrator of the Bureau of
Workers’ Compensation) therefore became a real party in interest and could
proceed in place of the claimant to protect the surplus fund. Id.
       {¶ 10} In response to Navistar’s motion, the commission asserts that
Youghiogheny does not apply here because that case involved a direct appeal to the
court of common pleas under former R.C. 4123.519 (now R.C. 4123.512), while
this case involves an original action in mandamus. But this distinction is of no
import, because the reasoning underlying this court’s conclusion in Youghiogheny
applies equally to a mandamus action. R.C. 4123.512(H)(1) broadly provides, “If,



                                         4
                                 January Term, 2020




in a final administrative or judicial action, it is determined that payments of
compensation or benefits, or both, made to or on behalf of a claimant should not
have been made, the amount thereof shall be charged to the [state] surplus fund
account.” (Emphasis added.) The plain language of this statute encompasses
actions in mandamus such as this. Youghiogheny’s framing of its holding in terms
of an appeal reflected the facts of that particular case, not a statutory limitation.
        {¶ 11} Notably however, since 2006, self-insured employers like Navistar
have had the ability to opt out of participation in the state surplus fund, and if they
do opt out, then they are not entitled to reimbursement from the fund. See R.C.
4123.512(H)(3); Am.Sub.S.B. No. 7, 151 Ohio Laws, Part I, 1019, 1071-1072
(amending R.C. 4123.512(H)). The record before this court does not indicate
whether Navistar opted out of participation in the fund.
        {¶ 12} But regardless of whether it participates in the surplus fund,
Navistar, as a self-insured employer, must pay to the state an annual assessment to
the safety-and-hygiene fund and must also pay administrative costs.                R.C.
4123.35(J). The amount of each assessment depends on the amount that Navistar
paid out in workers’ compensation benefits during the prior year. Id. And “any
amount that is determined not to have been payable to * * * a claimant in any final
administrative or judicial proceeding,” R.C. 4123.35(L), may be excluded from the
employer’s paid compensation for the year, Ohio Adm.Code 4123-17-32(B). See
also R.C. 4123.512(H)(1). The outcome of this appeal will therefore affect the
amount of the assessment that Navistar is required to pay to the state. Accordingly,
as in Youghiogheny, 11 Ohio St.3d 70, 464 N.E.2d 133, a continuing controversy
remains and the commission’s arguments on the merits serve to protect the state’s
interests in Navistar’s annual assessment (and the surplus fund, if applicable). We
therefore proceed to the merits of Navistar’s appeal.

                             B. Mandamus Standard
       {¶ 13} Mandamus relief is appropriate only if the relator establishes “a clear
legal right to the relief requested, a clear legal duty on the part of the commission
* * * to provide the relief, and the lack of an adequate remedy in the ordinary course
of the law.” State ex rel. Baker v. Indus. Comm., 143 Ohio St.3d 56, 2015-Ohio-
1191, 34 N.E.3d 104, ¶ 12. In matters before it, the commission is the exclusive
evaluator of the weight and credibility of the evidence. State ex rel. LTV Steel Co.
v. Indus. Comm., 88 Ohio St.3d 284, 287, 725 N.E.2d 639 (2000). Therefore, “[t]o
be entitled to an extraordinary remedy in mandamus, the relator must demonstrate
that the [commission] abused its discretion by entering an order not supported by
any evidence in the record.” State ex rel. WFAL Constr. v. Buehrer, 144 Ohio St.3d
21, 2015-Ohio-2305, 40 N.E.3d 1079, ¶ 12. The relator must make that showing
by clear and convincing evidence. Id.
                        C. Navistar’s Propositions of Law
       {¶ 14} Navistar asserts three propositions of law. First, it argues that the
commission abused its discretion by failing to address evidence of Bisdorf’s
voluntary retirement. Second, it argues that the reports of Drs. Rutherford and
Grunstein show that Bisdorf could have worked four hours a day and that the
commission abused its discretion by failing to consider various nonmedical factors
(e.g., Bisdorf’s age, education, and work record) before concluding that Bisdorf
could not engage in sustained remunerative employment. And third, it argues that
Dr. Rutherford’s opinion is conclusory and contradictory and that the commission
abused its discretion by relying on it. We reject the first two arguments and do not
reach the third.
                               1. Voluntary abandonment
       {¶ 15} “A      claimant’s     eligibility   for    permanent-total-disability
compensation may be affected if the claimant has voluntarily retired or abandoned
the job market for reasons not related to the industrial injury.” State ex rel. Black



                                          6
                                January Term, 2020




v. Indus. Comm., 137 Ohio St.3d 75, 2013-Ohio-4550, 997 N.E.2d 536, ¶ 14. Ohio
Adm.Code 4121-3-34(D), which provides guidelines that “shall be followed” by
the adjudicator of an application for PTD compensation, states:


               If, after hearing, the adjudicator finds that the injured worker
       voluntarily removed himself or herself from the work force, the
       injured worker shall be found not to be permanently and totally
       disabled. If evidence of voluntary removal or retirement is brought
       into issue, the adjudicator shall consider evidence that is submitted
       of the injured worker’s medical condition at or near the time of
       removal/retirement.


(Emphasis added.)       Ohio Adm.Code 4121-3-34(D)(1)(d).            Navistar’s first
proposition of law asserts that this regulation requires a hearing officer who is
adjudicating a claim for PTD compensation to consider evidence of a claimant’s
nondisability retirement and to address the issue of voluntary abandonment in the
subsequent order.
       {¶ 16} However, the existence of that obligation depends on whether
evidence of voluntary abandonment has been brought into issue. As we have
explained, “[b]ecause voluntary abandonment of all employment is an affirmative
defense and an issue critical to eligibility for compensation for permanent total
disability, if evidence of voluntary abandonment has been brought into issue, a
hearing officer’s failure to address the issue constitutes a mistake of law.” State ex
rel. Stevens v. Indus. Comm., 142 Ohio St.3d 313, 2015-Ohio-1352, 29 N.E.3d 972,
¶ 17, citing Ohio Adm.Code 4121-3-34(D)(1)(d). Conversely, however, the Tenth
District has concluded that if the defense of voluntary abandonment has not been
brought into issue at the SHO hearing, then it is an abuse of the hearing officer’s
discretion to address it, because the claimant has not been afforded due process,




                                          7
                             SUPREME COURT OF OHIO




i.e., sufficient notice and an opportunity to present evidence on the issue. State ex
rel. Jenkins v. Indus. Comm., 2017-Ohio-7896, 98 N.E.3d 944, ¶ 5 (10th Dist.).
Similarly, in State ex rel. Quarto Mining Co. v. Foreman, an employer argued that
the commission had abused its discretion by failing to initiate the issue whether
voluntary abandonment precluded PTD compensation. 79 Ohio St.3d 78, 81-83,
679 N.E.2d 706 (1997). This court refused to relax the rule that issues not
previously raised are waived and will not be considered by a reviewing court. Id.
This court went on to explain that relaxing that rule would “deny the claimant a
meaningful opportunity to respond,” id. at 82, and “forc[e] an already overworked
commission to comb the files of every PTD case in search of issues that could
potentially be raised by both sides at the hearing table,” id. at 82-83.
       {¶ 17} The question is, therefore, whether Navistar brought evidence of
voluntary abandonment into issue at the SHO hearing. While Navistar presented
no argument regarding voluntary abandonment to the commission prior to its
motion for reconsideration, Navistar asserts that it brought voluntary abandonment
into issue by presenting “written evidence and testimony related to the subject” at
the SHO hearing. However, this court rejected the same argument in Quarto
Mining. In that case, the employer argued that the issue of voluntary abandonment
“raises itself by virtue of being manifest in the record.” Id. at 81. This court
disagreed, stating that the employer has the burden “to raise and produce evidence
on its claim that other circumstances independent of the claimant’s allowed
conditions caused him to abandon the job market.” (Emphasis added.) Id. at 84.
       {¶ 18} Navistar attempts to distinguish Quarto Mining by pointing out that
the employer in that case first raised the issue of voluntary abandonment in a
petition for a writ of mandamus, while Navistar first argued the issue in its motion
for reconsideration before the commission. That distinction makes no difference:
either way, the claimant has been denied the opportunity to present evidence on the
issue. See Jenkins at ¶ 5; see also Quarto Mining at 81-82. The purpose of



                                          8
                               January Term, 2020




reconsideration of a hearing officer’s order is to address new or changed
circumstances, fraud, clear mistakes of law or fact, or errors by the hearing
officer—not to permit a party to present additional arguments or evidence that
could have been presented at the hearing. See Industrial Commission Resolution
No. R08-1-01.     In its motion for reconsideration, Navistar argued that the
commission had made a mistake of law by not addressing voluntary abandonment,
but, as explained above, that argument contradicts Quarto Mining.
       {¶ 19} Navistar did no more than the employer in Quarto Mining: it merely
presented evidence that could relate to voluntary abandonment and then waited for
the SHO to “initiate the issue,” Quarto Mining, 79 Ohio St.3d at 83, 679 N.E.2d
706. Navistar has not shown by clear and convincing evidence that it brought
Bisdorf’s alleged voluntary abandonment into issue at the SHO hearing.
Accordingly, we reject Navistar’s first proposition of law.
                              2. Four-hour work day
       {¶ 20} “ ‘Permanent total disability’ means the inability to perform
sustained remunerative employment due to the allowed conditions in the claim.”
Ohio Adm.Code 4121-3-34(B)(1). In its second proposition of law, Navistar argues
that Bisdorf could have worked four hours a day and that State ex rel. Bonnlander
v. Hamon, 150 Ohio St.3d 567, 2017-Ohio-4003, 84 N.E.3d 1004, therefore
required the commission to consider various nonmedical factors before granting
Bisdorf’s request for PTD compensation. See State ex rel. Stephenson v. Indus.
Comm., 31 Ohio St.3d 167, 173, 509 N.E.2d 946 (1987) (identifying age, education,
and work record as relevant nonmedical factors).
       {¶ 21} However, the commission is the exclusive finder of fact in workers’
compensation matters. State ex rel. Vonderheide v. Multi-Color Corp., 156 Ohio
St.3d 403, 2019-Ohio-1270, 128 N.E.3d 188, ¶ 7. And the commission did not find
that Bisdorf could have worked four hours a day. On the contrary, it found that
Bisdorf was incapable of performing any sustained remunerative employment




                                         9
                             SUPREME COURT OF OHIO




solely as a result of the medical impairments from his allowed physical conditions.
Accepting Navistar’s argument would require us to reject that factual determination
and substitute a new finding that Bisdorf was able to work four hours a day—an
improper invasion of the commission’s role as the exclusive fact-finder.
       {¶ 22} In addition, Bonnlander is inapposite. In Bonnlander, we rejected
an argument that the ability to work at least four hours a day necessarily means that
the claimant can engage in sustained remunerative employment. Bonnlander at
¶ 13-14, 20. Rather, we held that “there is no hourly standard for determining one’s
capability to perform sustained remunerative employment on a part-time basis. The
commission decides whether a claimant is capable of sustained remunerative
employment on a case-by-case basis.” Id. at ¶ 20.
       {¶ 23} Unlike in this case, the commission in Bonnlander found that the
claimant could work up to four hours per day. 150 Ohio St.3d 567, 2017-Ohio-
4003, 84 N.E.3d 1004, at ¶ 5. The commission then considered the nonmedical
factors listed in Stephenson, 31 Ohio St.3d at 173, 509 N.E.2d 946, and denied the
claimant’s request for PTD compensation.          Bonnlander at ¶ 6.     While the
commission may not deny PTD compensation without considering nonmedical
factors, it may grant PTD compensation without considering nonmedical factors
when “medical factors alone preclude sustained remunerative employment.” State
ex rel. Galion Mfg. Div., Dresser Industries, Inc. v. Haygood, 60 Ohio St.3d 38, 40,
573 N.E.2d 60 (1991). That is what occurred here: the commission concluded
based on medical evidence that Bisdorf could not work at all. Navistar’s argument
that the commission was required to consider the Stephenson nonmedical factors is
therefore not well-taken. Accordingly, we reject Navistar’s second proposition of
law.
                            3. Dr. Rutherford’s opinion
       {¶ 24} “[E]quivocal medical opinions are not evidence.” State ex rel.
Eberhardt v. Flxible Corp., 70 Ohio St.3d 649, 657, 640 N.E.2d 815 (1994).



                                         10
                                January Term, 2020




“[E]quivocation occurs when a doctor repudiates an earlier opinion, renders
contradictory or uncertain opinions, or fails to clarify an ambiguous statement.” Id.
In its third proposition of law, Navistar argues that Dr. Rutherford’s opinion is
equivocal on the question whether Bisdorf could have engaged in sustained
remunerative employment and that the commission abused its discretion by relying
on Dr. Rutherford’s opinion. However, this argument is immaterial, because the
commission relied on the reports of both Dr. Rutherford and Dr. Grunstein, and
even if we were to exclude Dr. Rutherford’s report as equivocal, Dr. Grunstein’s
report would constitute some evidence supporting the commission’s conclusion
that Bisdorf was incapable of sustained remunerative employment. See State ex
rel. Ehlinger v. Indus. Comm., 76 Ohio St.3d 400, 402, 667 N.E.2d 1210 (1996).
Accordingly, we do not reach Navistar’s third proposition of law.
                                D. Oral Argument
       {¶ 25} In a direct appeal such as this, the granting of a request for oral
argument is subject to this court’s discretion. S.Ct.Prac.R. 17.02(A). We typically
do not grant a request for oral argument unless the case involves (1) a matter of
great public importance, (2) complex issues of law or fact, (3) a substantial
constitutional issue, or (4) a conflict among courts of appeals. See State ex rel. BF
Goodrich Co., Specialty Chems. Div. v. Indus. Comm., 148 Ohio St.3d 212, 2016-
Ohio-7988, 69 N.E.3d 728, ¶ 23. Navistar’s motion for oral argument does not
address any of the above factors; Navistar argues only that the court of appeals
erred and misapplied the law. We therefore deny the motion for oral argument.
                               III. CONCLUSION
       {¶ 26} For these reasons, we grant Navistar’s motion to continue the case,
affirm the judgment of the Tenth District Court of Appeals, and deny Navistar’s
motion for oral argument.
                                                        Motion to continue granted
                                                            and judgment affirmed.

        KENNEDY, J., dissenting.
        {¶ 27} The narrow issue before this court is when and how an employer
must raise the defense of voluntary abandonment of employment when an injured
worker requests permanent-total-disability (“PTD”) compensation.
        {¶ 28} In this case, the Tenth District Court of Appeals determined that
appellant, Navistar, Inc., failed to present clear and convincing evidence that at an
administrative hearing before a staff hearing officer (“SHO”), it had raised a
defense asserting that appellee Gary E. Bisdorf had voluntarily abandoned the
workforce, precluding him from receiving PTD compensation. Citing State ex rel.
Jenkins v. Indus. Comm., 10th Dist. No. 16AP-534, 2017-Ohio-7896, ¶ 3-5, the
Tenth District held that voluntary retirement or abandonment of the workforce is
an affirmative defense and may not be raised in the first instance in a motion for
reconsideration. Rather, the court of appeals held that that defense must be raised
at the hearing in front of appellee Industrial Commission of Ohio. The Tenth
District further held that because Navistar failed to assert at the hearing that Bisdorf
had voluntarily retired or abandoned the workforce, Navistar waived the ability to
assert that defense in its complaint for a writ of mandamus. Although the magistrate
found that Navistar had “clearly raised” the issue before the commission and that
the commission had had a duty to address it, 2017-Ohio-8976, ¶ 77, the Tenth
District rejected that finding and returned the case to the magistrate for rulings on
additional assertions made by Bisdorf, id. at ¶ 22-23. The Tenth District did not
address the merits of Navistar’s voluntary-abandonment argument.
        {¶ 29} However, there are no pleading requirements, magic words, or
talismanic incantations needed to assert that an injured worker voluntarily



                                          12
                               January Term, 2020




abandoned the workforce. At Bisdorf’s PTD hearing, he testified that after working
at Navistar for 30 years, he voluntarily retired. Subsequently, he worked part-time
at a gun store for approximately six years. Bisdorf stopped working for reasons
unrelated to his workplace injury when the gun store closed, which occurred
approximately five years before he sought PTD compensation. At the hearing,
counsel for Navistar argued that Bisdorf had taken “regular retirement” and that he
was able to work while at the gun store and remained capable of working
afterwards. The record reflects that Navistar sufficiently raised the defense that
Bisdorf voluntarily retired or abandoned the workforce before becoming
permanently and totally disabled, and the SHO made a clear mistake of law in
failing to address that issue, warranting reconsideration by the commission.
        {¶ 30} Because the commission abused its discretion in failing to consider
evidence in the record indicating that Bisdorf voluntarily retired or otherwise
abandoned all employment before becoming permanently and totally disabled, I
would reverse the judgment of the Tenth District Court of Appeals and issue a writ
of mandamus directing the commission to vacate its award of PTD compensation.
        {¶ 31} Because the majority holds otherwise, I dissent.
        {¶ 32} R.C. 4123.54(A) provides that an injured worker “is entitled to
receive the compensation for loss sustained on account of the injury” as provided
by R.C. Chapter 4123. Relying on this language, we have explained that “[f]or
purposes of compensability, a causal relationship must exist between the
employee’s industrial injury and the loss that the requested benefit is designed to
compensate.” State ex rel. McCoy v. Dedicated Transport, Inc., 97 Ohio St.3d 25,
2002-Ohio-5305, 776 N.E.2d 51, ¶ 35. Therefore, in seeking PTD compensation,
the claimant has the burden “to establish that the disability is permanent and that
the inability to work is causally related to the allowed conditions.” State ex rel.
Sheppard v. Indus. Comm., 139 Ohio St.3d 223, 2014-Ohio-1904, 11 N.E.3d 231,
¶ 16.

          {¶ 33} This court has recognized that “[v]oluntary retirement precludes
[PTD] compensation.” State ex rel. Crisp v. Indus. Comm., 64 Ohio St.3d 507, 508,
597 N.E.2d 119 (1992). A claimant who retires or otherwise voluntarily abandons
employment for reasons unrelated to his or her injury cannot receive PTD
compensation, because it is the claimant’s own action, not the workplace injury,
that prevents the claimant from engaging in sustained remunerative employment.
State ex rel. Chrysler Corp., v. Indus. Comm., 62 Ohio St.3d 193, 196, 580 N.E.2d
1082 (1991). In those circumstances, the injury is not the proximate cause of the
inability to work. Sheppard at ¶ 20; see also State ex rel. Reliance Elec. Co. v.
Wright, 92 Ohio St.3d 109, 748 N.E.2d 1105 (2001) (“pre-PTD voluntary
abandonment of the labor force can be perceived as an intervening act that breaks
the nexus between an allowed condition and PTD”).
          {¶ 34} The administrative rules adopted by the commission align with this
precedent. Ohio Adm.Code 4121-3-34(D)(3)(a) places the burden on the injured
worker to prove by a preponderance of the evidence that “the disability is
permanent and that the inability to work is causally related to the allowed
conditions.” Further, under Ohio Adm.Code 4121-3-34(D)(3)(b), the SHO must
determine whether “the inability to work is due to the allowed conditions in the
claim,” and under Ohio Adm.Code 4121-3-34(D)(3)(g), the SHO must “review all
relevant factors in the record that may affect the injured worker’s ability to work.”
That includes considering whether a claimant’s inability to work has resulted from
retirement or other voluntary abandonment of employment; Ohio Adm.Code 4121-
3-34(D)(1)(d) states that “[i]f, after hearing, the adjudicator finds that the injured
worker voluntarily removed himself or herself from the work force, the injured
worker shall be found not to be permanently and totally disabled.” (Emphasis
added.)
          {¶ 35} Although this court has determined that retirement or other voluntary
abandonment of employment breaks the chain of cause and effect that is necessary



                                           14

to prove that a loss of employment resulted from a workplace injury, McCoy, 97
Ohio St.3d 25, 2002-Ohio-5305, 776 N.E.2d 51, at ¶ 36, this court has nonetheless
rejected the argument that “since it is [the] claimant’s burden to prove that his
disability is causally related to allowed conditions in the claim, it is necessarily
[the] claimant’s burden to prove that nonallowed conditions played no part in his
decision to retire,” State ex rel. Quarto Mining Co. v. Foreman, 79 Ohio St.3d 78,
83, 679 N.E.2d 706 (1997). Rather, we concluded that “[t]he burden should * * *
properly fall upon the employer to raise and produce evidence on its claim that
other circumstances independent of the claimant’s allowed conditions caused him
to abandon the job market.” Id. at 84. And for that reason, “the commission, in
evaluating a claimant’s application for PTD compensation, does not abuse its
discretion by failing to initiate the issue whether claimant’s retirement precludes
his or her eligibility for PTD compensation.” Id.
       {¶ 36} More recent cases have also described voluntary abandonment as an
affirmative defense, meaning that the burden of proof is on the employer to raise
and establish it. See State ex rel. Pacheco v. Indus. Comm., 157 Ohio St.3d 126,
2019-Ohio-2954, 132 N.E.3d 670, ¶ 26; State ex rel. Stevens v. Indus. Comm., 142
Ohio St.3d 313, 2015-Ohio-1352, 29 N.E.3d 972, ¶ 17. Navistar does not challenge
the appellate court’s characterization of voluntary retirement or abandonment of
employment as an affirmative defense, and we need not revisit that question to
decide this case.
       {¶ 37} Assuming that voluntary retirement or abandonment of employment
is an affirmative defense, the administrative rules do not impose any pleading
requirement for asserting it. For example, either party may request a prehearing
conference, Ohio Adm.Code 4121-3-34(C)(7), and at such a conference, each party
must be prepared to discuss evidence, if any, related to the injured worker’s
retirement and refusal to work, Ohio Adm.Code 4121-3-34(C)(8)(a) and (b). The
rule also states that the failure to request a prehearing conference or to raise a




                                        15
                             SUPREME COURT OF OHIO




defense at one “does not act to waive any assertion, argument, or defense that may
be raised at a hearing held under paragraphs (D) and (E),” Ohio Adm.Code 4121-
3-34(C)(7), including the defense of voluntary abandonment, Ohio Adm.Code
4121-3-34(D)(1)(d). And although Ohio Adm.Code 4121-3-34 provides a specific
procedure for reviewing applications for PTD compensation, it makes no other
reference to how or when defenses must be raised or preserved. Unlike the Rules
of Civil Procedure, the administrative rules do not include any formal requirements
for pleading a defense.
       {¶ 38} And we have never required magic words or talismanic incantations
to assert an affirmative defense in workers’ compensation cases. Rather, the
employer is required to “raise and produce evidence,” Quarto Mining Co., 79 Ohio
St.3d at 84, 679 N.E.2d 706, that is sufficient to put the claimant on notice that the
defense is at issue in order to allow “the claimant a meaningful opportunity to
respond,” id. at 82.
       {¶ 39} In this case, the evidence presented and the arguments raised created
a question of fact regarding whether Bisdorf severed the causal connection between
his workplace injury and his loss of sustained remunerative employment by retiring
and voluntarily abandoning all employment. Bisdorf testified that he had retired
from Navistar after working 30 years, and the commission previously found that he
had voluntarily retired in February 2003. He also testified that he could have
continued working, but he “was spending more time on the table getting operated
on than [he] was working.” Although he was not looking for a new job and
“considered [himself] retired,” he began working part-time as a sales associate and
firearms instructor at a gun store in May 2004. He stopped working at the gun store
when it went out of business in September 2010—not because he was incapable of
performing his job duties—and he did not look for another place of employment.
Bisdorf did not specifically testify that his lack of employment after the gun store
closed was due to his prior workplace injuries, but in any case, there is no medical



                                         16
                               January Term, 2020




evidence in the record that he was permanently and totally disabled at the time he
stopped working at the gun store or at any time during the next five years. Dr.
David M. Grunstein, a chiropractic physician, examined Bisdorf in October 2015
and found him to be permanently and totally disabled. Based on Dr. Grunstein’s
report, Bisdorf requested PTD compensation commencing on the date of that exam.
       {¶ 40} In summation at the hearing before the SHO, counsel for Navistar
pointed out that Bisdorf had taken “regular retirement” and had been able to
continue working at the gun store for six years. Pointing to another medical report,
counsel stated that at the time of Bisdorf’s retirement and during the time that he
worked at the gun store, his allowed conditions “had improved significantly.”
Counsel also pointed to evidence that Bisdorf was still capable of doing sedentary
work. While counsel did not use the magic words “voluntary retirement or other
abandonment of all employment,” the import of his argument was that at the time
Bisdorf stopped working and long afterward, he was not permanently and totally
disabled.
       {¶ 41} A hearing officer is required to “ ‘specifically state what evidence
has been relied upon in reaching the conclusion.’ ” State ex rel. Penske Truck
Leasing Co., L.P. v. Indus. Comm., 153 Ohio St.3d 133, 2018-Ohio-2153, 101
N.E.3d 456, ¶ 12, quoting Ohio Adm.Code 4121-3-34(D)(3)(h). But in granting
Bisdorf PTD compensation, the SHO’s order stated only, “Based upon the reports
of James Rutherford, M.D., dated 03/15/2016, and David Grunstein, D.C., dated
10/22/2015, it is found that the Injured Worker is unable to perform any sustained
remunerative employment solely as a result of the medical impairment caused by
the allowed physical conditions.” However, neither of those reports provided any
medical evidence that the allowed conditions prevented Bisdorf from working after
the gun store closed in September 2010. Tellingly, the commission awarded
compensation beginning in October 2015, even though Bisdorf had stopped
working more than five years earlier, and the order points to no evidence that the




                                        17
                             SUPREME COURT OF OHIO




workplace injury prevented him from seeking other employment after the gun store
closed. The order simply ignores this gap in the record.
       {¶ 42} PTD compensation may not be granted unless the injured worker has
met his or her burden to prove that the allowed conditions caused the inability to
work. Ohio Adm.Code 4121-3-34(D)(3)(a) and (b). And when evidence presented
at the hearing indicates that the injured worker retired or otherwise voluntarily
abandoned employment for reasons unrelated to the injury, that evidence must be
considered and weighed by the hearing officer in deciding whether proximate cause
was established. See Sheppard, 139 Ohio St.3d 223, 2014-Ohio-1904, 11 N.E.3d
231, at ¶ 21 (explaining that the hearing officer is required address voluntary
abandonment, proximate cause, and “all relevant factors in the record that may
affect the claimant’s ability to work”).
       {¶ 43} In my view, Navistar sufficiently presented and preserved the
argument that Bisdorf voluntarily abandoned the workforce before he became
permanently and totally disabled. If the majority believes that the evidence and
argument presented at the hearing was insufficient, then what is sufficient? This
court should provide guidance to practitioners and the commission regarding what
words an employer must say in order to trigger the commission’s duty to consider
evidence that the injured worker voluntarily retired or otherwise abandoned
employment. If magic words or a talismanic incantation are needed, the court
should say so. If the majority believes that notice in writing before the hearing is
required, then it should say that and the commission should include the requirement
in Ohio Adm.Code 4121-3-34.          However, the majority falls short of telling
practitioners and parties what is expected of them going forward, and they should
take notice that the failure to use the right language at the hearing could foreclose
any finding that the injured worker voluntarily retired or abandoned employment,
no matter how strong the evidence of it in the record is.

       {¶ 44} During the SHO hearing, Navistar presented the commission with
evidence that Bisdorf had voluntarily retired from the workforce before he became
permanently and totally disabled. And that issue should have been addressed when
Navistar filed its motion for reconsideration. The commission abused its discretion
by failing to determine whether Bisdorf had voluntarily removed himself from the
workforce and whether he was ineligible for PTD compensation for that reason.
       {¶ 45} Therefore, I would reverse the judgment of the court of appeals and
issue a writ of mandamus ordering the commission to vacate its award of PTD
compensation.
