Task: songer_casetyp1_1-2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "criminal". 

PER CURIAM.
This appeal is from an order of the District Court denying a motion under Rule 32(d) of the Rules of Criminal Procedure to set aside a judgment of conviction and permit appellant to withdraw a plea of guilty and re-enter a plea of not guilty, where the guilty plea was made after trial but before verdict and where the District Court held a full hearing on the allegations presented by appellant.
We affirm the order of the District Court upon the opinion of Judge Follmer, 37 F.R.D. 360. We agree with him that this appeal is frivolous, completely without merit and shows no evidence of having been filed in good faith.
The order of the District Court will be affirmed.
