Tom C. Clark,
Jackson v. Taylor — Opinion of the Court
“ Review of a court-martial conviction is first provided by the convening authority-the commanding officer who directed that the case be tried before a court-martial. He is empowered to reduce a sentence though he cannot increase it. He can weigh facts, determine credibility of witnesses, disapprove findings of guilt which he believes erroneous in law or fact, and determine sentence appropriateness without regard to what the court-martial might have done had it considered only the approved findings. ”
