Section 15
SEC. 15. The first and fourth paragraphs of Article fifty of Commonwealth Act Numbered Four hundred and eight, are hereby amended to read, respectively as follows: "ART. 50. Review-Rehearing.—The Judge Advocate General of the Armed Forces of the Philippines shall constitute, in his office, a board of review consisting of one or more officers of the Judge Advocate General's Service." "When the President or any reviewing or confirming authority disapproves or vacates a sentence the execution of which has not heretofore been duly ordered, he may authorize or direct a rehearing. Such rehearing shall take place before a court composed of officers not members of the court which first heard the case. Upon such rehearing the accused shall not be tried for any offense of which he was found not guilty by the first court, and no sentence in excess of or more severe than the original sentence shall be imposed unless the sentence be based upon a finding of guilty of an offense not considered upon the merits In the original proceedings: Provided, That such rehearing shall be had in all cases where a finding and sentence have been vacated by reason of the action of the board of review approved by the Judge Advocate General holding the record of trial legally insufficient to support the findings or sentence or errors of law have been committed injuriously affecting the substantial rights of the accused, unless in accord with such action, and the recommendations of the Judge Advocate General thereon, the findings or sentence are approved in part only, or the record is returned for revision, or unless the case is dismissed by order of the reviewing or confirming authority. After any such rehearing had on the order of the President, the record of trial shall, after examination by the board of review, be transmitted by the Judge Advocate General, with the Board's opinion and his recommendations, to the Chief of Staff for the action of the President."
