18 U.S.C. § 3584

18 U.S.C. § 3584 addresses how federal courts can impose consecutive or concurrent sentences for multiple convictions. When a person is sentenced for more than one crime, the court can decide whether those sentences will run at the same time (concurrently) or one after the other (consecutively). The overall goal is to ensure that the punishment fits the nature of the offenses and respects legal guidelines, allowing judges flexibility to determine an appropriate total sentence based on the specifics of each case.
