MANILA - The Supreme Court, sitting as the Presidential Electoral Tribunal (PET), has junked the motion of Vice President Leni Robredo's camp to consider 25 percent of oval shading as a valid vote.

In a resolution dated April 10, PET said it has "no basis to impose a 25% threshold in determining whether a vote is valid."

"The Court is not aware of any COMELEC (Commission on Elections) Resolution that states the applicability of a 25% threshold; and the Tribunal cannot treat the Random Manual Audit Guidelines and Report as proof of the threshold used by the COMELEC," the resolution read.

"In fact, COMELEC Resolution No. 8804, as amended by COMELEC Resolution No. 9164, which is COMELEC’s procedure for the recount of ballots in election protests within its jurisdiction, does not mention a 25% threshold."

Robredo's camp earlier filed a motion urging PET to follow Comelec's Random Manual Audit Guidelines and Report.

"In her Ex Parte Motion, Protestee claims that the threshold percentage in determining the validity of votes during the 2016 National and Local Elections was 25% and not 50%," the resolution read.

"The Protestee's claim that the Commission on Elections, as purportedly confirmed by the Random Manual Audit Guidelines and Report, applies the 25% threshold percentage in determining a valid vote is inaccurate."

The PET, meanwhile, ordered Robredo and former Senator Bongbong Marcos to explain within 10 days from receipt of notice of the show cause order why they should not be held in contempt for violating the gag order on the vote recount.

It explained that it had released two resolutions dated February 13, 2018, and March 20, 2018, which instruct both parties to refrain from discussing the vote recount to the public.

The recount of votes for the election protest of Marcos against Robredo began last April 2.

Both camps have given statements to the media on the matter in the days that followed.

Marcos claims "massive cheating" caused his loss to Robredo in the 2016 vice-presidential race by some 260,000 votes. --Report from Michael Delizo, ABS-CBN News; DZMM
