Text: Our standard of review in this case is limited. We review de novo legal determinations by the Veterans Court. Prenzler v. Derwinski, 928 F.2d 392, 393 (Fed. Cir. 1991). We have jurisdiction over all relevant questions of law, including interpretations of constitutional and statutory authority. 38 U.S.C. § 7292(d)(1). Absent a constitutional question, we do not possess jurisdiction to review any challenge to a factual determination or the application of law or regulation to the facts of a particular case. Guillory, 603 F.3d at 986. Therefore, we do not have jurisdiction to review whether the evidence presented in a particular case meets the applicable legal standard. See, e.g., Waltzer v. Nicholson, 447 F.3d 1378, 1380 (Fed. Cir. 2006).
