NRS 412.418
Approval and execution or suspension of sentence.
1.
Except as otherwise provided in NRS 412.316 to 412.433, inclusive, a court-martial sentence, unless suspended, may be ordered executed by the convening authority when approved by him or her. The convening authority shall approve the sentence or such part, amount or commuted form of the sentence as he or she sees fit, and may suspend the execution of the sentence as approved by him or her.2.
If the sentence of the court-martial includes dismissal, a dishonorable discharge or a bad-conduct discharge and if the right of the accused to appellate review is not waived and an appeal is not withdrawn, that part of the sentence extending to dismissal, a dishonorable discharge or a bad-conduct discharge must not be executed until there is a final judgment as to the legality of the proceedings. A judgment as to the legality of the proceedings is final in such cases when review is completed by an appellate court prescribed in NRS 412.432, and is deemed final by the law of the state where judgment was had.3.
If the sentence of the court-martial includes dismissal, a dishonorable discharge or a bad-conduct discharge and if the right of the accused to appellate review is waived or an appeal is withdrawn, the dismissal, dishonorable discharge or bad-conduct discharge may not be executed until review of the case by the senior force judge advocate and any action on that review is completed. The convening authority or other person acting on the case under the Code when so approved under this section may order any other part of a court-martial sentence executed immediately.
