Section 14
SEC. 14. Any Justice of the Supreme Court who held any office or position under the Philippine Executive Commission or under the government called Philippine Republic may not sit and vote in any case brought to that Court under section thirteen hereof in which the accused is a person who held any office or position under either or both the Philippine Executive Commission and the Philippine Republic or any branch, instrumentality and/or agency thereof. If, on account of such disqualification, or because of any of the grounds of disqualification of judges in Rule 126, section 1 of the Rules of Court, or on account of illness, absence or temporary disability the requisite number of Justices necessary to constitute a qourum or to render judgment in any case is not present, the President may designate such number of Judges of First Instance, Judges-at-large of First Instance, or Cadastral Judges, having none of the disqualifications set forth in said section one hereof, as may be necessary to sit temporarily as Justices of said Court, in order to form a quorum or until a judgment in said case is reached.
