Section 38. Section 15 of Republic Act No. 7166 is hereby amended to read as follows:

"Sec. 15. Pre-proclamation Cases in Elections for President, Vice-President, Senator, and Member of the House of Representatives. — For purposes of the elections for president, vice-president, senator, and member of the House of Representatives, no pre-proclamation cases shall be allowed on matters relating to the preparation, transmission, receipt, custody and appreciation of election returns or the certificates of canvass, as the case may be, except as provided for in Section 30 hereof. However, this does not preclude the authority of the appropriate canvassing body motu propio or upon written complaint of an interested person to correct manifest errors in the certificate of canvass or election returns before it.

"Questions affecting the composition or proceedings of the board of canvassers may be initiated in the board or directly with the Commission in accordance with Section 19 hereof.

"Any objection on the election returns before the city or municipal board of canvassers, or on the municipal certificates of canvass before the provincial board of canvassers or district board of canvassers in Metro Manila Area, shall be specifically noticed in the minutes of their respective proceedings."
