Ezra Charles Calloway, Sr., a Maryland state prisoner, seeks to appeal the order of the district court denying his request that the District of Columbia Board of Parole be instructed to hold a parole revocation hearing to determine if he violated his parole in the District of Columbia. We find that Calloway’s action is properly construed as a petition for mandamus relief. See Johnson v. Reilly, 349 F.3d 1149, 1153 (9th Cir. 2003); Heath v. United States Parole Commission, 788 F.2d 85, 89 (2d Cir. 1986). The Board of Parole filed a detain-er with the Maryland Division of Correction. There is, however, “no constitutional duty to provide [a parolee] an adversary parole hearing until he is taken into custody as a parole violator by execution of [a] warrant.” Moody v. Daggett, 429 U.S. 78, 89, 97 S.Ct. 274, 50 L.Ed.2d 236 (1976); Larson v. McKenzie, 554 F.2d 131, 132-33 (4th Cir. 1977); Gaddy v. Michael, 519 F.2d 669, 677 (4th Cir. 1975). We affirm the district court’s order denying Calloway relief, as Calloway has not yet been taken into custody as a parole violator. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
