MANILA - President Rodrigo Duterte's proclamation voiding the amnesty of Senator Antonio Trillanes is presumed to be regular unless proven otherwise by a court, the military said Wednesday.

Duterte withdrew the amnesty that absolved Trillanes of charges over 2 failed military uprisings due to the latter's alleged failure to properly apply for amnesty and express guilt for his crime.

• Trillanes to stay in Senate custody, won't surrender

"Ang atin pong Armed Forces, as a professional organization, looks at the Proclamation 572 with presumption of regularity on the part of the public officer performing his duty," military spokesman Col. Edgard Arevalo told radio DZMM.

"Lahat po ng issues, challenges or doubt regarding the regularity or legality ng Presidential Proclamation 572 na inissue ng Presidente, that could be addressed to the court," he said.

(All issues, challenges or doubt regarding the regularity or legality ng Presidential Proclamation 572 issued by the President could be addressed to the court.)

Until a court rejects Duterte's proclamation, security forces have a mandate to return Trillanes to the custody of the military, which will resume court martial proceedings against him, said Arevalo.

• Trillanes to face court martial, says AFP

Trillanes was among the leaders of the Magdalo band of junior officers and soldiers who took over the Oakwood luxury apartments in Makati on July 2003 to protest alleged corruption under then President Gloria Macapagal-Arroyo

In 2007, the group walked out of their coup d'etat hearing and took over the Manila Peninsula hotel, also in Makati, in another protest against Arroyo.

Duterte's predecessor, former President Benigno Aquino, granted amnesty to Trillanes and several other military rebels in 2011, leading to his release from detention.

The Department of Defense on Tuesday said Trillanes' application for amnesty was missing and that it has exhausted all efforts to find the document.

The senator will be detained at Camp Aguinaldo in Quezon City if his custody is given to the military, added its spokesperson.

Trillanes said he will seek a halt order against the invalidation of his amnesty. He said said he will stay in the custody of the Senate and will not turn himself over to the arresting authorities.
