Michigan § 32.1063 - Disapproval by convening authority of findings and sentence; reasons; rehearing; dismissal of charges; sentence.

If the convening authority disapproves the findings and sentence of a court-martial, the convening authority, except where there is lack of sufficient evidence in the record to support the findings, may order a rehearing. The convening authority shall state the reasons for disapproval. If the convening authority disapproves the findings and sentence and does not order a rehearing, the convening authority shall dismiss the charges.

Each rehearing shall take place before a court-martial whose composition shall not include a member or military judge of the court-martial which first heard the case. Upon a rehearing the accused may not be tried for an offense of which the accused was found not guilty by the first court-martial. A sentence in excess of or more severe than the original sentence shall not be imposed, unless the sentence is based upon a finding of guilty of an offense not considered upon the merits in the original proceedings, or unless the sentence prescribed for the offense is mandatory.
