Section 3582(c)(2) empowers district judges to correct sentences that depend on frameworks that later prove un-justified.

In Freeman v. United States, No. 0910245 (June 23, 2011), the Court addressed whether defendants who enter into an 11(c)(1)(C) plea agreements that recommend a particular sentence as a condition of the guilty plea may be eligible for retroactive relief under §3582(c)(2) (covering retroactive application of Guideline amendments) if the sentence later proves to be unjustified.
