2 O'CONNELL v. MCDONOUGH

PER CURIAM. Michael Gregg O’Connell served in the United States Marine Corps from April 1983 to April 1987, spending much of that period at Camp Lejeune. In 2010, Mr. O’Con- nell applied to the Department of Veterans Affairs (VA) for disability benefits, claiming entitlement based on several conditions, including an inability to have children. Mr. O’Connell alleged that these conditions were connected to his service—specifically, to his exposure to contaminated water at Camp Lejeune. In a 2012 rating decision, the relevant VA regional of- fice found no service connection for the conditions now at issue, including loss of use of a creative organ and inability to have children. Mr. O’Connell submitted a notice of dis- agreement with that determination, and the Board of Vet- erans’ Appeals remanded the dispute of this claim to the regional office several times between 2012 and 2020 for fur- ther examinations and record development. Eventually, in a March 2022 decision, the Board denied this disputed claim, determining that, although Mr. O’Connell had been exposed to contaminated water at Camp Lejeune, he lacked a diagnosis of infertility and the evidence showed that any such disability, if found, was less likely than not related to contaminated water exposure or any service-connected dis- ability. Supplemental Appendix (SAppx)17–23. The United States Court of Appeals for Veterans Claims (Vet- erans Court) affirmed the Board’s decision. O’Connell v. McDonough, No. 22-1720, 2023 WL 6210881 (Vet. App. Sept. 25, 2023). Mr. O’Connell appeals the Veterans Court’s decision, presenting three arguments to this court. First, Mr. O’Con- nell argues that the Veterans Court “failed to recognize the findings of the ATSDR,” seemingly referring to the Agency for Toxic Substances and Disease Registry, “and its water modeling of the Camp Le[j]eune toxic chemicals and their effects on humans.” Appellant’s Informal Br. at 2.

O'CONNELL v. MCDONOUGH 3

Mr. O’Connell argues that the Board did not give adequate weight to a book that he had cited as evidence to support his claim. Mr. O’Connell alleges that the Board failed to recognize the academic credentials of one of the book’s au- thors and suggests that the author was more qualified than an expert whose opinion the Board credited. Third, Mr. O’Connell argues that the Board erred by failing to men- tion several specific chemicals that he alleges were present at Camp Lejeune. The statute defining our jurisdiction declares that, when no constitutional issue is presented, our authority is limited to addressing legal issues decided by the Veterans Court, 38 U.S.C. § 7292(a), and we “may not review . . . a challenge to a factual determination, or . . . a challenge to a law or regulation as applied to the facts of a particular case,” § 7292(d)(2). See § 7292(a), (c), (d). Under the stat- ute, we lack the authority to address Mr. O’Connell’s argu- ments and hence lack jurisdiction over this appeal. Mr. O’Connell challenges only the Veterans Court’s af- firmance of the Board’s factual determinations and the Board’s application of law to facts, and he neither raises a constitutional issue nor identifies a legal issue decided by the Veterans Court. Appellant’s Informal Br. at 1–2 (Mr. O’Connell’s statement that the Veterans Court’s decision did not “involve the validity or interpretation of a statute or regulation” and did not “decide constitutional issues”). We may not address Mr. O’Connell’s challenges to the weighing of evidence. See Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000) (“The weighing of this [record] evi- dence is not within our appellate jurisdiction.”). Moreover, there is no apparent decision by the Veterans Court, ex- press or implied, regarding the Agency for Toxic Sub- stances and Disease Registry, much less a decision about a legal issue involving the registry, as Mr. O’Connell did not present an argument to the Veterans Court about the reg- istry. See SAppx26–58. Case: 24-1277 Document: 16 Page: 4 Filed: 06/04/2024

4 O'CONNELL v. MCDONOUGH

Because we do not have the authority to review Mr. O’Connell’s challenges to the Veterans Court’s decision, we must dismiss his appeal for lack of subject-matter jurisdic- tion. The parties shall bear their own costs. DISMISSED
