When a judge decides a motion at court-martial they will present the facts they have found, discuss the law, and make their conclusion. On appeal, when the military judge makes proper findings of fact, the court will accept those facts for the purpose of review unless there is an abuse of discretion and the facts found are “clearly erroneous.”
C.A.A.F. seems to have this definition, among several, of what clearly erroneous means.
At least one court has defined the clearly-erroneous standard by stating that it must be "more than just maybe or probably wrong; it must … strike us as wrong with the force of a five-week-old, unrefrigerated dead fish."
