Luz Velez de Ramos, the spouse and court-appointed guardian of Luis A. de Ramos, seeks review of a judgment of the United States Court of Appeals for Veterans Claims (“Veterans Court”) denying service connection for her husband’s acquired psychiatric disorder. See De Ramos v. Shinseki, No. 07-0857, 2009 WL 278832, 2009 U.S.App. Vet. Claims LEXIS 89 (Feb. 5, 2009). We dismiss for lack of jurisdiction.

Our authority to review a decision of the Veterans Court is limited by statute. See 38 U.S.C. § 7292. We may review such a decision only to the extent that it pertains to “the validity of any statute or regulation ... or any interpretation thereof (other than a determination as to a factual matter),” or “to interpret constitutional and statutory provisions, to the extent presented and necessary to a decision.” Id. §§ 7292(a), 7292(c). Absent a constitutional issue, we do not have jurisdiction to review either “a challenge to a factual determination” or “a challenge to a law or regulation as applied to the facts of a particular case.” Id. § 7292(d)(2); see McGee v. Peake, 511 F.3d 1352, 1355 (Fed.Cir. 2008). Because de Ramos’ appeal presents only challenges to factual determinations regarding whether her husband’s psychiatric disorder was incurred in service, it falls outside the scope of our appellate authority.

No costs.
