c. All cases in which the jurisdiction of any lower court is in issue.
d. All criminal cases in which the penalty imposed is reclusion perpetua, life imprisonment, or death.

Such rules shall provide a simplified and inexpensive procedure for the speedy disposition of cases, shall be uniform for all courts of the same grade, and shall not diminish, increase or modify substantive rights. Rules of procedure of special courts and quasi-judicial bodies shall remain effective unless disapproved by the Supreme Court.
6. Appoint all officials and employees of the Judiciary in accordance with the Civil Service Law.
Section 6. The Supreme Court, through the Office of the Court Administrator, shall have administrative supervision over all courts and their personnel.

A Member of the Supreme Court must be at least 40 years old and must have been a judge of a lower court or engaged in the practice of law in the Philippines for at least 15 years.
(2) Parliament shall prescribe the qualifications of judges of lower courts, but no person may be appointed judge unless he is a citizen of the Philippines and a member of the Philippine Bar.
(3) A Member of the Judiciary must be a person of proven competence, integrity, probity, and independence.

Section 9. The decision of the Judicial and Bar Council, in the exercise of its disciplinary powers as provided in the preceding Section, shall be appealable on certiorari to the Supreme Court.
Section 10. The Prime Minister shall appoint justices of all collegiate courts and judges of lower courts from among the list submitted by the Judicial and Bar Council within 90 days from the submission of the list. Such appointment needs no confirmation.
Section 11. The salary of the Chief Justice, the Associate Justices of the Supreme Court, justices of collegiate courts and judges of lower courts shall be fixed by law. During their continuance in office, their salary shall not be decreased and upon retirement, they shall all be covered by a uniform retirement plan prescribed by law.

Section 14. The conclusions of the Supreme Court in any case submitted to it for decision en banc or in division shall be reached in consultation before the case is assigned to a Member for the writing of the opinion of the Court. A certification to this effect signed by the Chief Justice shall be issued and a copy shall be attached to the record of the case and served upon the parties. Any Members who took no part, dissented, or abstained from a decision or resolution must state the reason. The same requirements shall be observed by all collegiate and lower courts.
Section 15. No decision shall be rendered by any court without expressing clearly and distinctly the facts and the law on which it is based. No petition for review or motion for reconsideration of a decision of the court shall be refused due course or denied without stating the legal basis for the refusal or denial.
Section 16.

(2) A case or matter shall be deemed submitted for decision or resolution upon the filing of the last pleading, brief, or memorandum required by the Rules of Court or by the court itself.
(3) Upon the expiration of the corresponding period, a certification to this effect signed by the Chief Justice or the presiding judge shall forthwith be issued and a copy of which shall be attached to the record of the case or matter, and served upon the parties. The certification shall state why a decision or resolution has not been rendered or issued within said period. The unjustified failure to render a decision or resolution within the mandatory periods may be a ground for the impeachment of the Members of the Supreme Court or the imposition of sanctions, including removal, against a collegiate court justice or judge.
(4) Despite the expiration of the applicable mandatory period, the court, without prejudice to such responsibility as may have been incurred as a consequence, thereof, shall decide or resolve the case or matter submitted to the court for determination, without further delay.
