MANILA -- Senate President Vicente Sotto III said Wednesday the chamber would issue regulations on the "flow and entry" of armed men in the chamber's premises after police were reportedly stationed outside its building.
Sen. Antonio Trillanes, who is facing arrest after his amnesty was voided, has been holed up at the Senate since Tuesday and Sotto said he could not be arrested there.
"The Senate secretary might issue a memorandum to that effect para hindi maabuso 'yan (so that it won't be abused)," Sotto told reporters.
"There is nothing wrong if there are police, soldiers outside the Senate premises" but any "armed component of any institution of government" must inform us before entering our premises, he said.
Senators are finalizing the terms of Trillanes' temporary stay in the Senate building, Sotto said.
Trillanes said he would question the withdrawal of amnesty before the courts. He prepared a petition for a temporary restraining order with his lawyers overnight.
Trillanes was granted amnesty in 2011, absolving him of charges in connection with failed military uprisings in 2003 and 2007. Justice Secretary Menardo Guevara said the amnesty was void from the start since the lawmaker failed to apply for it properly.
Trillanes said he was "confident" that the Senate leadership would not succumb to political pressure.
"I'm sure Senator Sotto is subjected to all kinds of political pressure but he values the importance of institutions," Trillanes said.
