expressly waives the defect impacting only parole eligibility, we will not permit the defendant to manipulate the judicial system by subsequently insisting that the sentence conform to the forty-percent provision. Here, the sentences agreed upon by the parties, and which the court ultimately imposed, were part of a voluntary and knowing plea, and appellant expressly waived any defects associated with the minimum and maximum terms of his sentences. Under these circumstances, we will not interfere with the sentences imposed. See United States v. Barnes, 83 F.3d 934, 941 (7th Cir. 1996) (upholding a plea agreement that provided for a sentence which departed from the prescriptions of federal sentencing guidelines); United States ex rel. Ferris v. Finkbeiner, 551 F.2d 185 (7th Cir. 1977) (<HOLDING>). Our holding today is not inconsistent with
holding that although defendant is not entitled to appeal from his guilty plea as a matter of right his arguments challenging the factual basis for his guilty plea are reviewable pursuant to a petition for writ of certiorari holding that when the defendant was misadvised when entering his guilty plea that he would not have to serve a mandatory parole term following his release from prison fundamental fairness required limiting the term of his sentence to that which comported with the plea bargain holding that the failure to notify the defendant of the term of supervised release and its possible effect on his sentence was not harmless error where njothing in the record suggests that the defendant understood that his sentence would include supervised release andthere was no written plea agreement by which he might have been warned holding that a defendant must have knowledge of the likely consequences of entering the guilty plea in order for a plea to be voluntary and knowing holding that the failure to notify the defendant of the term of supervised release and its possible effect on his sentence was not harmless error where nothing in the record suggests that the defendant understood that his sentence would include supervised release and there was no written plea agreement by which he might have been warned
