MANILA - Senator Antonio Trillanes IV on Tuesday said his camp was studying the possibility of him going home later in the evening or on Wednesday, even as the Supreme Court denied his petition for a preliminary injunction.

The lawmaker, who has been holed up in his Senate office since President Rodrigo Duterte voided his amnesty, welcomed the Supreme Court ruling, even if it did not issue a temporary restraining order, because "the bottomline is hindi mae-effect yung arrest."

"Pag ginawa nila yan, ito na. Kumbaga, they run the risk of getting cited for contempt by openly defying the Supreme Court decision and at the same time, we will have all the legal remedies available to us—habeas corpus, filing of appropriate charges to these arresting personalities," he told reporters.

"Mag-uusap kami, we will convey our decision to the Senate President later on," he said.

The Supreme Court has been "heavily suspected of being partial to the Duterte administration," but it showed "some semblance of independence," through its decision, Trillanes said.

"They could outrightly dismiss the petition altogether, but they took a stand in some way so that’s good enough...Malaking departure pa rin yan, we’ll take that," he said.

Duterte has invalidated Trillanes' amnesty for supposed failure to comply with amnesty requirements, and ordered military and the police to "employ all lawful means" to arrest the senator.

Trillanes argued he satisfied all the prerequisites of the amnesty, which was even concurred in by Congress.

Two local courts are set to decide on a Department of Justice motion to issue arrest warrants and hold departure orders, pending Trillanes' comments and hearings scheduled on September 13 and 14.
