Iowa. R. Crim. P. 2.8
Comment: Alford pleas are permitted in the court's discretion, so long as the plea meets the requirements of this rule. See North Carolina v. Alford, 400 U.S. 25, 37-38 (1970) (discussing the basis for the Alford plea procedure); State v. Knight, 701 N.W.2d 83, 89 (Iowa 2005) (noting that "the district court has discretion to accept" Alford pleas from defendants).
Comment: Revised rule 2.8(5) is not intended to modify existing law as to when a defendant who pleads guilty may withdraw that plea. However, there was a concern that former rule 2.8(2)(a) did not reflect current law because it could be read as providing for unfettered trial judge discretion regarding the withdrawal of a guilty plea at any time before judgment.
