The denial of Appellant’s Rule 3.800(a) motion is affirmed without prejudice to the extent Appellant is challenging the Florida Parole Commission’s determination of his release date. Appellant may file a proper petition in the appropriate jurisdiction. See Sheley v. Fla. Parole Comm’n, 720 So .2d 216, 217 (Fla. 1998) (“[A Petition for Writ of] Mandamus is an accepted remedy for reviewing an order of the Florida Parole Commission.”).
