Rules of Court.
Section 6
SEC. 6. Rules of Court. — The judges of the Supreme Court shall prepare rules regulating the conduct of business in the Supreme Court and in the Courts of First Instance. The rules shall be uniform for all Courts of First Instance throughout the Islands. Such rules, when duly made and promulgated and not in conflict with the laws of the United States or of the Philippine Islands, shall be binding and must be observed, but no judgment shall be reversed by reason of a failure of the court to comply with such rules unless the substantial rights of a party have been impaired by such failure.
