SEC. 6. (a) Subsection (h) of section thirteen of said Act is hereby amended by changing the word "possible" to "practicable" wherever found in said subsection, and by striking out the words "and following as nearly as possible in the provisions of these laws any agreements heretofore, made by the United States authorities with such local or tribe rulers concerning the power and privileges which under American sovereignty they are by such agreements to enjoy: Provided, That they have not by their conduct and the breach of the agreements forfeited such powers and privileges."
(b) Subsection (j) of said section thirteen is hereby amended so as to read as follows:
"(j) To enact laws amending and modifying the substantive civil and criminal law of the Philippine Islands to suit local conditions among the Moros and other non-Christian inhabitants of the province, and to cause such laws to conform, when practicable, to the local customs and usages of such inhabitants. It shall not be necessary that such laws shall apply uniformly to all localities; but differing provisions may be made applicable to different localities as the legislative council shall determine. The substantive law as thus amended and modified shall apply in all civil actions in which each of the parties is either a Mom or a member of some other non-Christian tribe, and in all criminal actions as to such of the accused as are Moros or members of some other non-Christian tribe. In all other civil actions and in all criminal actions as to accused who are neither Moros nor members of some other non-Christian tribe, the substantive criminal and civil law of the Philippine Islands shall apply and be in force as in other provinces: Provided, That in civil actions the parties to which are in part Moros or members of some other non-Christian tribe, and in part Christian Filipinos or Americans or subjects or citizens of a foreign country, it shall be within the discretion of the court to apply the substantive law as amended in accordance with the provisions of this section, in so far as the interests of such Moros or other non-Christians are directly affected, or the substantive law of the Philippine Islands, as the circumstances of each case and the interests of justice may require."
(c) Subsection (k) of said section thirteen is hereby amended so as to read as follows:
"(k) To enact laws for the organization and procedure of local tribal ward courts to consider and decide minor civil actions in which the parties in interest, or any of them, are Moros or members of some other non-Christian tribe, and minor criminal actions in which the accused, or any of them, are Moms or members of some other non-Christian tribe. Tribal ward courts shall, within the limits defined in the preceding sentence, have and exercise the jurisdiction now or hereafter vested by law in courts of justice of the peace, but the legislative council may, in its discretion, vest in such courts jurisdiction in other actions, civil or criminal, not capital, original jurisdiction in which is at present vested in Courts of First Instance. In each district the governor and secretary of the district shall be justices of tribal ward courts and there shall be as many auxiliary justices as may be needed. The legislative council shall provide for the appointment and compensation of the auxiliary justices, and for the holding of such sessions of the court at such times and places throughout the district as the efficient administration of justice may render necessary. An appeal shall be from every judgment of a tribal ward court to the Court of First Instance of the district and on such appeal the action shall be tried de novo: Provided, That the sentences of the tribal ward courts from which no appeal is taken to the Court of First Instance may he modified or remitted by the provincial governor after a review of the case."
