The presence of six Justices shall be necessary to constitute a quorum except when the judgment of the lower court imposes the death penalty, in which case the presence of eight Justices shall be necessary to constitute a quorum.In the absence of a quorum, the Court shall stand ipso facto adjourned until such time as the requisite number shall be present, and a memorandum showing this fact shall be inserted by the clerk in the minutes of the court.
" If on account of illness, absence, or incapacity upon of the grounds mentioned in Section one, Rule One "Hired and thirty-seven of the Rules of Court, of any the Justices of the Supreme Court, or whenever, by reason of temporary disability of any Justice thereof, or vacancies occurring therein, the requisite number of Justices necessary to constitute a quorum or to render a judgment in any given case, as heretofore provided, is not present, the President of the Philippines, upon the recommendation of the Chief Justice, may designate such number of Justices of the Court of Appeals or District Judges as may be necessary, to sit temporarily as Justices of the Supreme Court in order to form a quorum, or until a judgment in said case is reached: Provided, however, That no Justice of the Court of Appeals or District Judge may be designated to act in any case in the decision of which he has taken part.
"The concurrence of at least six Justices of the Court shall be necessary for the pronouncement of a judgment. However, for the purpose of declaring a law or a treaty unconstitutional, at least eight Justices must concur. When the necessary majority, as herein provided, to declare a law or a treaty unconstitutional cannot be had, the Court shall so declare, and in such case the validity or constitutionality of the Act or treaty involved shall be deemed upheld.
"Whenever the judgment of the lower court imposes the death penalty, the case shall be determined by eight Justices of the Court. When eight Justices fail to reach a decision as to the propriety of the imposition of the death penalty, the penalty next lower in degree shall be imposed."
