A group of bishops, former military and police officials and IT experts is poised to file a petition asking the Supreme Court to compel the Commission on Elections (Comelec) to use the voter verification paper audit trail (VVPAT), one of the four minimum security requirements mandated by law, in the May 9 elections.

The Reform Philippines Coalition on Wednesday said it will file a petition for mandamus at the High Court on the first week of March.
