235, 239 (Fed.Cir.1988). On appeal, Mr. Baney does not challenge the Board’s determination that collateral estoppel bars his leave-related claims. We agree with the Board that Mr. Baney’s claims are barred by collateral estoppel because they challenge the same issues that Mr. Baney actually litigated and that were necessary to the decisions in previous proceedings. See, e.g., Baney v. Dep’t of Justice, 409 Fed.Appx. 319 (Fed.Cir.2010) (finding no USERRA violation for charging Mr. Baney with eleven and a half hours of AWOL in November 2008); Baney v. Dep’t of Justice, 263 Fed.Appx. 892 (Fed.Cir.2008) (finding no USERRA violation for charging Mr. Baney with 23 days of leave while on active military duty for 30 days); see also Baney v. Dep’t of Justice, 327 Fed.Appx. 895 (Fed.Cir.2009) (<HOLDING>). Accordingly, we affirm the Board’s decision
holding that because relitigation of issue was barred by collateral estoppel res judicata determination of finality of judgment dismissed for lack of standing was not relevant holding that collateral attacks on bankruptcy courts jurisdiction are barred by res judicata holding that the plaintiffs claims were barred by res judicata when the federal courts judgment was finalized by denial of his petition for certiorari holding that mr baneys challenge to being charged with 208 hours of annual leave while on active military duty for 30 days was barred by the res judicata effects of our 2008 decision holding that a trustees claim was barred by res judicata and stating that the trustee could have asked the bankruptcy court to reserve his fraud claims for later adjudication which would have avoided his claims being barred
