A case in which the Court decided that a sentence imposed pursuant to a Federal Rule of Criminal Procedure 11(c)(1)(C) (“Type C”) plea bargain is “based on” the defendant’s Federal Sentencing Guidelines range as long as that range was a component of the framework the court used in imposing the sentence or accepting the plea bargain, meaning that in this case, Erik Hughes could seek a sentencing reduction under 18 U.S.C. § 3582(c)(2).
