(2) If it appears to the judge advocate, within the period of 56 days beginning with the day on which the sentence was imposed— (a) that the court had no power to impose such a sentence, or (b) that the maximum term for which the court had power to impose such a sentence has expired, the judge advocate may order that the offender be immediately released. (3) The power conferred by this rule may not be exercised in relation to any sentence if an appeal, or an application for leave to appeal, against the sentence has been determined. (4) This rule is without prejudice to any other provision of this Part.
