Whether a district court violates the Sentencing Reform Act's ban on imprisonment as a rehabilitative measure

QUESTION PRESENTED The Sentencing Reform Act prohibits federal courts from imposing or lengthening a prison term to promote rehabilitation. 18 U.S.C. § 3582(a); Tapia v. United States, 564 U.S. 319 (2011). In the present case, the court of appeals held the district court’s sentence of ten years’ imprisonment not to run afoul of that proscription. The question presented is: Whether a district court violates the Sentencing Reform Act’s ban on imprisonment as a rehabilitative measure when, as here, the court explains it is imposing a “lengthy” prison term so that the defendant will “get rid of drugs” and “learn ... to follow rules and regulations.” i
