Today in Dean v. United States, the Supreme Court unanimously held that a district court may consider the consecutive mandatory sentence required under 18 U.S.C. 924(c) when imposing the sentence to be served on the underlying offense. You can access the opinion here. The length of the mandatory consecutive sentence bears on the factors to be considered under 18 U.S.C. 3553(a), such as the need to protect the public and to provide adequate deterrence.
“Nothing in § 924(c) restricts the authority conferred on sentencing courts by § 3553(a) and the related provisions to consider a sentence imposed under § 924(c) when calculating a just sentence for the predicate count,” the Court explained. In other words, “nothing . . . prevents a district court from imposing a 30-year mandatory minimum sentence under § 924(c) and a one-day sentence for the predicate violent or drug trafficking crime, provided those terms run one after the other.”
This overturns Second Circuit precedent on this point, see US v. Chavez, 549 F.3d 119, 133-35 (2d Cir. 2008), although many Eastern and Southern District judges have been persuaded to impose sentences of time-served or other short sentences on the underlying offense in light of the 924(c) mandatory sentence.
