Task: Wrong Candidate Generation
Input (English): (“It is immaterial that [the defendant’s] firearm purchase and domestic violence conviction occurred prior to [18 U.S.C.] § 922(g)(9)’s enactment because the conduct prohibited by [18 U.S.C.] § 922(g)(9) is the possession of a firearm .... [Thus,] the application of [18 U.S.C.] § 922(g)(9) to [the defendant] does not run afoul of the ex post facto prohibition.”); United States v. Boyd, 52 F.Supp.2d 1233, 1236-37 (D.Kan.1999), aff'd 211 F.3d 1279 (10th Cir.2000), (concluding the illegal act was not completed until after 18 U.S.C. § 922(g)(9) became effective because the illegal act in 18 U.S.C. § 922(g)(9) is the possession of the firearm, not the misdemeanor domestic violence conviction); United States v. Meade, 986 F.Supp. 66, 69 (D.Mass.1997), aff'd 175 F.3d 215 (1st Cir.1999), (<HOLDING>); NAGE, Inc. v. Barrett, 968 F.Supp. 1564, 
 Holding statements: (A) holding that 18 usc  3559c did not violate separation of powers doctrine or ex post facto clause (B) holding that revocation of medical license does not violate the ex post facto clause (C) holding the use of a 1951 felony conviction as a predicate for a violation of 18 usc  922g1 did not violate the ex post facto clause because the crime of being a felon in possession of a firearm was not committed until after the effective date of the statute under which he was convicted (D) holding ex post facto clause barred application of mvra to defendant whose criminal conduct occurred before the effective date of the statute (E) holding 18 usc  922g9 penalizes the possession of a firearm after its effective date and therefore does not constitute a violation of the ex post facto clause
