This type of motion is specifically for those convicted in the state of Minnesota by the U.S. District Court for the District of Minnesota. There are two types of Minnesota Motion to Vacate — 2255: a 2255(a) motion, which applies to those who have been convicted of a federal offense, and a 2255(b) motion, which applies to those who have been convicted of a state offense.
