Appeal from the Court of Workers’ ) Heard March 24, 2020, at Knoxville
Compensation Claims )
Thomas L. Wyatt, Judge )
Vacated and Remanded—Corrected 1
The employee filed a petition alleging she suffered a mental injury as a result of work-
related events in which she experienced unusual traumatic stimuli while working as a
forensics technician for the employer. The employer filed a motion for summary
judgment, asserting that, even if a mental injury occurred, the employee failed to file her
claim within the applicable statute of limitations. The employee responded by asserting
that the statute of limitations was tolled until May 2018, when she discovered her mental
condition was causally related to her employment, or, alternatively, that her mental injury
is a gradual injury to which the “last day worked” rule applies. At a hearing addressing
the employer’s motion, the parties agreed that the specific incidents the employee alleged
to have precipitated her mental injury occurred in 2011 or earlier, prompting the trial
court to question whether it had jurisdiction over the case. However, the court declined
to rule on the jurisdiction issue, focusing instead on whether a genuine issue of material
fact existed that precluded summary judgment. The trial court denied the employer’s
motion, concluding there was a disputed factual issue concerning when the employee
knew or should have known that she suffered an injury. The employer has appealed. We
vacate the trial court’s order denying the employer’s summary judgment motion and
remand the case for the trial court to determine whether the Court of Workers’
Compensation Claims has subject matter jurisdiction.
Judge David F. Hensley delivered the opinion of the Appeals Board in which Presiding
Judge Timothy W. Conner and Judge Pele I. Godkin joined.

Memorandum Opinion 2
Angela Varner Nickerson (“Employee”) worked for the Knox County Government
as a technician in the Forensics Department of the Knox County Sheriff’s Department
(“Employer”) for approximately eleven years until she was assigned to Employer’s
Special Services Department in 2011. She alleges she suffered a mental injury as a result
of her forensics work. Specifically, she asserts she experienced two traumatic encounters
involving children, including the death of a child in one case and severe physical and
sexual abuse of a child in another case. Both encounters occurred in or before 2011.
Employee filed a petition for benefits on April 29, 2019, alleging she experienced
symptoms of post-traumatic stress disorder (“PTSD”) increasing in severity over time,
prompting her to seek reassignment to a different department in 2011 and, ultimately, to
leave her employment with the Sheriff’s Department. She identified the date of injury in
her petition as June 12, 2018.
Employer denied the claim, asserting Employee did not file her claim timely, and
it filed a motion for a summary judgment asserting it was entitled to a judgment as a
matter of law based upon the alleged late filing of Employee’s petition. Employee
responded that the applicable statute of limitations was suspended by application of the
discovery rule, arguing that she did not know her symptoms were causally related to her
employment until she was diagnosed with PTSD on May 7, 2018. Alternatively, she
argued her mental injury was a gradual injury to which the “last day worked” rule
applies, resulting in her date of injury being the last day she worked for the Sheriff’s
Department, which was less than one year before she filed her petition for benefits.
Employer disputed the application of both rules, asserting Employee knew or should have
known the work-related nature of her alleged mental injury in 2015 when she sought
mental health treatment for problems she related to her employment. Employer
additionally argued that Tennessee does not recognize a mental injury as a gradual injury,
and that the “last day worked” rule was inapplicable to Employee’s claim.
At the hearing of Employer’s summary judgment motion, counsel for Employer
stated that “as far as the incidents . . ., I think we all agree they occurred sometime prior
to 2011, or on or before 2011,” which prompted the following statements by the court:

“The Appeals Board may, in an effort to secure a just and speedy determination of matters on appeal and
with the concurrence of all judges, decide an appeal by an abbreviated order or by memorandum opinion,
whichever the Appeals Board deems appropriate, in cases that are not legally and/or factually novel or
complex.” Appeals Bd. Prac. & Proc. § 1.3.
2
[T]hat in and of itself, seems like it raises some issue about the jurisdiction
of the Court that I don’t think either one of you have really addressed in
this particular case.
I’m aware that this summary judgment is about the statute of limitations
and not about the particular date of injury, but it does seem at some point
we’re going to address when the injury arose. If it arose prior to July 1,
2014, you’re in the wrong court. I think we all know that.
But I’m not going to chase that rabbit today. We’ve got a big enough rabbit
to chase with this statute of limitations issue.
But I want to alert you that, as I worked through this and thought about it,
that is an issue that I think one day we’ll have to address if this case
proceeds further . . . .”
The court asked counsel for Employee whether Employee’s position was that she
suffered a gradual injury “as opposed to a single traumatic-type injury,” to which counsel
responded, “[i]t is.”
The trial court denied Employer’s summary judgment motion, stating the
following:
Looking at the evidence on summary judgment in the light most favorable
to [Employee], the Court holds a genuine factual issue exists as to whether
[Employee] knew or should have known more than a year before she filed
her [petition] that she had work-related PTSD. For that reason, summary
judgment is inappropriate, and the Court denies [Employer’s] motion.
In a footnote, the court stated that because it denied Employer’s motion, it was
“unnecessary to decide [Employee’s] alternative gradual-injury theory.” Employer has
appealed the trial court’s order denying its summary judgment motion.
At the outset of oral arguments that were conducted on March 24, 2020, we
expressed to the parties that the case presented an issue of subject matter jurisdiction that
had not been addressed in the parties’ briefs, noting that the jurisdiction of the Court of
Workers’ Compensation Claims and the Appeals Board is limited to cases having a date
of injury on or after July 1, 2014. See Tenn. Code Ann. §§ 50-6-237, -217 (2019). The
parties requested additional time to brief the jurisdiction issue, which we agreed was
appropriate. Both parties timely submitted excellent briefs addressing the jurisdiction
issue.
As we have previously observed,

It is well-established that questions regarding a court’s subject matter
jurisdiction address the court’s “lawful authority to adjudicate a
controversy brought before it . . . and, therefore, should be viewed as a
threshold inquiry.” Redwing v. Catholic Bishop for the Diocese of
Memphis, 363 S.W.3d 436, 445 (Tenn. 2012). A court derives its subject
matter jurisdiction from the Tennessee Constitution or from statutes, Staats
v. McKinnon, 206 S.W.3d 532, 542 (Tenn. Ct. App. 2006), as opposed to
conduct or agreement of the parties, Shelby County v. City of Memphis, 365
S.W.2d 291, 292 (Tenn. 1963). Thus, the parties cannot confer subject
matter jurisdiction on a court by “appearance, plea, consent, silence, or
waiver.” Dishmon v. Shelby State Cmty. Coll., 15 S.W.3d 477, 480 (Tenn.
Ct. App. 1999). In the absence of subject matter jurisdiction, orders entered
by a court are invalid and unenforceable. Suntrust Bank v. Johnson, 46
S.W.3d 216, 221 (Tenn. Ct. App. 2000).
Yarbrough v. Protective Servs. Co., No. 2015-08-0574, 2016 TN Wrk. Comp. App. Bd.
LEXIS 3, at *6-7 (Tenn. Workers’ Comp. App. Bd. Jan. 25, 2016). Moreover, “the issue
of subject-matter jurisdiction may be raised at any time during the proceedings, by the
parties or by the court. A court may raise the issue of subject-matter jurisdiction sua
sponte, even where no party objects.” Wilken v. Wilken, No. W2012-00989-COA-R3-
CV, 2012 Tenn. App. LEXIS 907, at *10-11 (Tenn. Ct. App. Dec. 27, 2012) (citations
omitted).
In its supplemental brief, Employer asserts the Court of Workers’ Compensation
Claims does not have jurisdiction based upon Employee’s admission that her alleged
mental injury arises from two identifiable work-related events that occurred in or before
2011. Employer asserts the date of injury for a mental injury “is self-evident by virtue of
its definition,” noting the statutory definition requires a loss of mental faculties or
behavioral disorder “arising primarily out of a compensable physical injury or an
identifiable work-related event resulting in a sudden or unusual stimulus.” Based upon
Employee’s assertion that the sudden or unusual stimuli here involved events occurring in
or before 2011, Employer contends the trial court does not have jurisdiction.
Anticipating that Employee would contend her mental injury is an occupational disease
for which the date of injury is the date of “partial or total incapacity for work” resulting
from the disease, Employer cites Gatlin v. City of Knoxville, 822 S.W.2d 586 (Tenn.
1991), for the proposition that a mental disorder caused by gradual stress and strain
cannot be an occupational disease. Finally, Employer asserts the “last day worked” rule,
which is applicable to gradual injuries under the Workers’ Compensation Reform Act of
2013, does not apply to “purely mental injuries arising from an identifiable work-related
event, or series of events, resulting in a sudden or unusual stimulus.”
In her supplemental brief, Employee likewise emphasizes the statutory definition
of “mental injury,” but asserts the definition includes two distinct qualifying phrases or
4
provisions that must be met before a “mental injury” exists. First, Employee contends
section 50-6-102(17) requires that the mental injury “must manifest itself” in the form of
“a loss of mental faculties or a mental or behavioral disorder.” Second, Employee says
the statute requires that the “loss of mental faculties or the mental or behavioral disorder”
must be “attributable to ‘a compensable physical injury or an identifiable work related
event resulting in a sudden or unusual stimulus.’” Further, Employee posits that the
statutory definition does not require that “the elements necessary to constitute a ‘mental
injury’ be simultaneous, concurrent or instantaneous.”
Stating these requirements in different terms, Employee contends that an
employee who experiences an identifiable work-related event or series of events that
qualifies as a sudden or unusual stimulus does not suffer a mental injury simply by the
occurrence of the experience or event; rather, the occurrence of the experience or event
results in a mental injury only if and when the employee sustains a “loss of mental
faculties or a mental or behavioral disorder as a result of the experience or event.” As
argued by Employee, in this case there was no mental injury until she suffered a loss of
mental faculties or a mental or behavioral disorder, which she says occurred long after
the 2011 events and after the effective date of the Workers’ Compensation Reform Act of
2013, thereby vesting subject matter jurisdiction in the Court of Workers’ Compensation
Claims.
Neither an analysis nor a resolution of the parties’ respective arguments on the
jurisdiction issue is necessary to resolve this appeal. We conclude the trial court erred in
ruling on the summary judgment motion prior to determining whether the court had
subject matter jurisdiction. It is not our role, in the first instance, to decide issues that
should have been presented to the trial court. See Keyes v. Bridgestone Ams., No. 2016-
06-2007, 2017 TN Wrk. Comp. App. Bd. LEXIS 33, at *6 (Tenn. Workers’ Comp. App.
Bd. May, 18, 2017) (“The role of an appellate court is not to hear matters in the first
instance, but to review trial courts’ dispositions of the matters before
them.”). Accordingly, the trial court’s order denying Employer’s summary judgment
motion is vacated, and the case is remanded for the trial court to determine whether
subject matter jurisdiction exists. Costs on appeal are taxed to Employer.
