Policy statements governing the acceptance of plea agreements under Rule 11(c), Fed. R. Crim. P., are intended to ensure that plea negotiation practices: (1) promote the statutory purposes of sentencing prescribed in 18 U.S.C. § 3553(a); and (2) do not perpetuate unwarranted sentencing disparity.
These policy statements make clear that sentencing is a judicial function and that the appropriate sentence in a guilty plea case is to be determined by the judge.
