Subd. 1. To Correct Manifest Injustice. At any time the court must allow a defendant to withdraw a guilty plea upon a timely motion and proof to the satisfaction of the court that withdrawal is necessary to correct a manifest injustice. Such a motion is not barred solely because it is made after sentencing. If a defendant is allowed to withdraw a plea after sentencing, the court must set aside the judgment and the plea.
Subd. 2. Before Sentence. In its discretion the court may allow the defendant to withdraw a plea at any time before sentence if it is fair and just to do so. The court must give due consideration to the reasons advanced by the defendant in support of the motion and any prejudice the granting of the motion would cause the prosecution by reason of actions taken in reliance upon the defendant's plea.
Subd. 3. Withdrawal of Guilty Plea Without Asserting Innocence. The defendant may move to withdraw a plea of guilty without an assertion of not guilty of the charge to which the plea was entered.
