Before DYK, HUGHES, and STOLL, Circuit Judges. STOLL, Circuit Judge. This case returns to us for a second time. Lisa Afolayan petitioned the Bureau of Justice Assistance’s denial of death benefits following the death of her husband, Agent Nathaniel Afolayan. In Ms. Afolayan’s first petition for re- view, we remanded the case for the Bureau to determine whether the climatic conditions at the time of Agent Afolayan’s death were unusual, nonroutine, or unusually adverse. On remand from this court, the Bureau deter- mined that because the climatic conditions on April 30, 2009, in Artesia, New Mexico, were not unusual, nonrou- tine, or unusually adverse, Agent Afolayan did not sustain a compensable injury. We affirm. BACKGROUND I Under the Public Safety Officers’ Benefits Act (“Bene- fits Act”), when the Bureau determines that “a public safety officer has died as the direct and proximate result of a personal injury sustained in the line of duty,” the Bureau must pay a death benefit to the surviving family of the of- ficer. 34 U.S.C. § 10281(a). The regulation defines “injury” to include: [A] traumatic physical wound (or a traumatized physical condition of the body) directly and proxi- mately caused by external force (such as bullets, explosives, sharp instruments, blunt objects, or physical blows), chemicals, electricity, climatic Case: 24-1692 Document: 48 Page: 3 Filed: 04/17/2026

conditions, infectious disease, radiation, virus, or bacteria. 28 C.F.R. § 32.3 (emphasis added). II Because this case is before us for a second time, the fol- lowing facts have been taken from our prior decision in Afolayan v. Department of Justice, No. 2021-1452, 2022 WL 1124965 (Fed. Cir. Apr. 15, 2022) (“Afolayan I”). At the time of his death, Agent Afolayan was in the last week of a twelve-week training program at the Border Pa- trol Academy in Artesia, New Mexico. At approximately 2:45 p.m. on April 30, 2009, Agent Afolayan and other agents-in-training performed their final physical-fitness test, which included a one-and-a-half mile run to be com- pleted in thirteen minutes or less. The run took place at approximately 3,400 feet above sea level, with the temper- ature at approximately 88 degrees Fahrenheit and relative humidity between six and seven percent. After completing the run in eleven minutes and six seconds, Agent Afolayan indicated that he did not feel well and thereafter collapsed. He was initially brought to the Border Patrol Academy’s Health Unit for medical assistance. As his condition de- clined, he was taken first to Artesia General Hospital, then to Covenant Medical Center in Lubbock, Texas. Agent Afolayan died at 10:41 p.m. the next day. Agent Afolayan’s death certificate listed his “immediate cause of death as ‘Heat Illness’ and identified ‘cardiomegaly (cardiac dis- ease)’ as an ‘other significant condition[ ] contributing to death.’” Afolayan I at *1 (alteration in original). Ms. Afolayan filed a claim for death benefits under the Benefits Act in October 2009, relying on the death certifi- cate listing “Heat Illness” as the cause of death. The Bu- reau denied her claim in March 2012. Ms. Afolayan appealed this denial and requested a determination of her claim by an independent hearing officer. The hearing of- ficer denied Ms. Afolayan’s appeal in January 2014. In Case: 24-1692 Document: 48 Page: 4 Filed: 04/17/2026
February 2019, Ms. Afolayan appealed the hearing officer’s determination to the Bureau’s Director. In Septem- ber 2020, the Acting Director of the Bureau concluded from the medical evidence in the record that: Agent Afolayan died—not from a wound or condi- tion shown to have itself been ‘the direct and prox- imate result’ of climatic conditions, such as heat, or another external force/factor cognizable as an ‘in- jury’ under [Benefits Act] regulations—but, rather, as a result of several factors acting together, in- cluding physical exertion, sickle cell trait, heat, al- titude, and dehydration. Id. at *2 (citation omitted). This led the Acting Director to conclude that Ms. Afolayan failed to “establish[ ] that Agent Afolayan suffered an ‘injury’ within the meaning of [the Benefits Act] and its implementing regulations.” Id. (alterations in original) (citation omitted). Ultimately, the Acting Director denied Ms. Afolayan’s claim, after which Ms. Afolayan filed a petition for review in this court. Id. In Afolayan I, we held that “climatic conditions” refers to conditions that are “unusual” or “nonroutine”—“that is, conditions different from the typical conditions prevailing in the work environment.” Id. at *3. We then remanded the case back to the Bureau to determine whether the tem- perature, humidity, and altitude “were the type of unusual or out-of-the-ordinary climatic conditions that would qual- ify for compensation under the regulations.” Id. at *4. III On remand, the Director of the Bureau examined past weather patterns and medical opinions and concluded that it was “more likely than not” that the climatic conditions did not cause Agent Afolayan’s medical crisis. J.A. 27. Ac- cordingly, the Director again denied Ms. Afolayan’s claim. Ms. Afolayan petitions for review of the Bureau’s deci- sion. We have jurisdiction under 34 U.S.C. § 10287.

AFOLAYAN v. DOJ 5
DISCUSSION Before us, Ms. Afolayan asserts that the Bureau erred in its determination that Agent Afolayan did not sustain an injury because the climatic conditions were not unusual, nonroutine, or unusually adverse. We disagree. Because we affirm the Bureau’s conclusion that Agent Afolayan did not sustain a compensable “injury” due to unusual, nonrou- tine, or unusually adverse climatic conditions, we need not address the other issues raised by Ms. Afolayan’s petition. We review the Bureau’s denial of a claim for death ben- efits for: “(1) whether there has been substantial compli- ance with statutory requirements and provisions of implementing regulations; (2) whether there has been any arbitrary or capricious action on the part of the government officials involved; and (3) whether substantial evidence supports the decision denying the claim.” Amber-Messick v.

AFOLAYAN v. DOJ 5
DISCUSSION Before us, Ms. Afolayan asserts that the Bureau erred in its determination that Agent Afolayan did not sustain an injury because the climatic conditions were not unusual, nonroutine, or unusually adverse. We disagree. Because we affirm the Bureau’s conclusion that Agent Afolayan did not sustain a compensable “injury” due to unusual, nonrou- tine, or unusually adverse climatic conditions, we need not address the other issues raised by Ms. Afolayan’s petition. We review the Bureau’s denial of a claim for death ben- efits for: “(1) whether there has been substantial compli- ance with statutory requirements and provisions of implementing regulations; (2) whether there has been any arbitrary or capricious action on the part of the government officials involved; and (3) whether substantial evidence supports the decision denying the claim.” Amber-Messick v. United States, 483 F.3d 1316, 1321 (Fed. Cir. 2007) (first citing Yanco v. United States, 258 F.3d 1356, 1362 (Fed. Cir. 2001); and then citing Chacon v. United States, 48 F.3d 508, 511 (Fed. Cir. 1995)). “Substantial evidence is defined as ‘[t]he degree of relevant evidence that a rea- sonable person, considering the record as a whole, might accept as adequate to support a conclusion even though other reasonable persons might disagree.’” Giove v. Dep’t of Transp., 230 F.3d 1333, 1338 (Fed. Cir. 2000) (alteration in original) (citation omitted). We hold that substantial evidence supports the Bu- reau’s finding that the climatic conditions were not unu- sual, nonroutine, or unusually adverse. The climatic conditions that existed on the day of Agent Afolayan’s run include an elevation approximately 3,400 feet above sea level, with the temperature at approximately 88 degrees Fahrenheit and relative humidity between six and seven percent. The evidence considered by the Bureau showed that the temperatures during the month of April for every year between 2000 to 2009 in Artesia, New Mex- ico, could reach at least 87 degrees Fahrenheit. J.A. 5–6 & Case: 24-1692 Document: 48 Page: 6 Filed: 04/17/2026
nn.12–16. 1 Past humidity patterns in Artesia, New Mexico showed that for most days in April 2009, the humidity fell below 10 percent. J.A. 6 & nn.19–20. Evidence regarding the effect of the combination of temperature and humidity on the body in outdoor conditions was shown via the heat index, in particular the wet bulb black globe temperature (WBGT), which at 88 degrees Fahrenheit and seven per- cent humidity is 71 degrees. J.A. 7 & n.26. Based on a WBGT of 71 degrees, the guidelines from the U.S. Army, U.S. Soccer, and the American College of Sports Medicine did not identify any risks to individuals participating in outdoor work or activities. J.A. 7–10 & nn.28–36. Litera- ture regarding altitude and its effect on the human body identified that an altitude of 3,400 feet above sea level would not typically create adverse physiological reactions. J.A. 12–14. Here, considering all the evidence together, substantial evidence supports the Bureau’s determination that the climatic conditions, individually and in combina- tion, were not unusual, nonroutine, or unusually adverse at the time of Agent Afolayan’s medical crisis. Ms. Afolayan argues that the Bureau’s decision is erro- neous because it failed to consider whether the combina- tion of temperature, humidity, and altitude was unusual for the “work environment” of a Border Patrol Officer. Pet. Br. 50. Ms. Afolayan argues that the Bureau’s decision lacks any discussion regarding typical working conditions and that the sources cited by the Bureau are silent regard- ing the effect of temperature and humidity on altitude. Pet. Br. 51–53. We are not persuaded. The Bureau specif- ically addressed the combination of temperature, humidity, and altitude and determined that the combination of these
1 The evidence that the Bureau relied on consists of various websites, databases, and guidelines that are cited in the Bureau’s decision. See J.A. 5–14 & nn.12–16, 19–22, 24–36. There is no dispute that this evidence was proper for the Bureau to rely on in its analysis. Case: 24-1692 Document: 48 Page: 7 Filed: 04/17/2026
AFOLAYAN v. DOJ 7
factors was not unusual, nonroutine, or unusually adverse when Agent Afolayan went on his outdoor physical fitness run. J.A. 14. While the Bureau did not rely on a reference that examined temperature, humidity, and altitude to- gether, the Bureau’s analysis sufficiently considered these three factors and its determination is supported by sub- stantial evidence. Ms. Afolayan also asserts that 28 C.F.R. § 32.3, the regulation defining “injury,” uses the bare term “climatic conditions,” and does not require conditions that are unu- sual, nonroutine, or unusually adverse. Pet. Br. 43–49. But we already resolved this very question in Afolayan I, when we held that “climatic conditions,” as defined in the Benefits Act and its implementing regulations, must be “unusually adverse” or “different from the typical condi- tions prevailing in the work environment.” Afolayan I at *3 (quoting Juneau v. Dep’t of Just., 583 F.3d 777, 783 (Fed. Cir. 2009)). Because this question was resolved in our previous decision in Afolayan I, law of the case prohib- its Ms. Afolayan from reraising this issue. See Suel v. Sec’y of Health & Hum. Servs., 192 F.3d 981, 984–986 (Fed. Cir. 1999) (explaining that under the law of the case doctrine, what was previously decided in an earlier stage of the case is applied to subsequent stages in the litigation). We have tremendous sympathy for Agent Afolayan’s family. However, because substantial evidence supports the Bureau’s decision, we cannot say that the Bureau erred in its determination that Agent Afolayan did not sustain an “injury” as contemplated by the Benefits Act. CONCLUSION For the reasons stated above, we affirm the Bureau’s decision denying Ms. Afolayan’s claim. AFFIRMED COSTS No costs.
