SEC. 13. When certificate of canvass is incomplete or bears erasures or alterations.—When the certificate of canvass,, duly certified by the Board of Canvassers of each province or city, and transmitted to the Speaker of the Batasang Pambansa as provided in the Constitution, appears to be incomplete, the Speaker shall require the Board of Canvassers concerned to transmit to his office, by personal delivery, the statement from voting centers that were not included in the returns transmitted. Said supplemental certificate of canvass shall be prepared in the same manner as provided for in Section ten hereof and submitted by personal delivery to the Speaker within two days from receipt of notice. When it appears that any certificate of canvass or supporting statement of votes by precinct bears erasures or alterations which may cast doubt as to the veracity of the number of votes stated therein and may affect the result of the election, the Batasang Pambansa upon request of the presidential candidate concerned or his party shall, for the sole purpose of verifying the actual number of votes cast for President count the votes as they appear in the statement of election returns from all the precincts in the province or city in question; and for this purpose, the Speaker shall require, the Provincial Election Officer or City Registrar concerned to deliver personally to the Batasang Pambansa the copy of such statements of election returns canvassed by the provincial or city board of canvassers; and may also require the Commission on Elections to place its copy of such statements of election returns at the disposal of the Batasang Pambansa.
