The ICC Warrant Against Senator Bato and the Limits of Arrest
MAY 11, 2026, may be remembered as one of the most politically charged days in recent Philippine history.
The 20th Congress impeached Vice President Duterte. Senate leadership shifted from Senator Vicente Sotto to Senator Allan Peter Cayetano. Senator Ronald ‘Bato’ Dela Rosa returned to the Senate building. Soon after, reports broke that an ICC warrant had allegedly been issued against him.
Then came reports that the NBI, together with former Senator Trillanes, sought to serve the warrant and arrest Senator Dela Rosa.
The public question was immediate: may a senator “hide inside the Senate” to avoid arrest?
Under the 1987 Constitution, the answer is generally “No.”
A senator enjoys privilege from arrest only while Congress is in session, and only for offenses punishable by not more than six years imprisonment. It is a narrow privilege, not a sanctuary. It was never meant to convert the Senate into a refuge against criminal process.
But in Senator Dela Rosa’s case, the deeper legal issue is not parliamentary immunity. Congress may be in session, but the real question is this: may an ICC warrant be directly enforced in the Philippines without first passing through Philippine courts?
Dean Melencio Sta. Maria, a political commentator and one of my former professors in Ateneo Law whom I deeply respect, recently took the position that Republic Act No. 9851 allows Philippine cooperation with international tribunals investigating crimes against humanity. He points to Section 17, which recognizes the surrender of persons to international tribunals when appropriate.
According to him, this is consistent with the principle that crimes against humanity are universal crimes, especially since Article II, Section 2 of the Constitution provides that the Philippines adopts generally accepted principles of international law as part of the law of the land. He further argues that an ICC warrant issued by a foreign judge may justify an arrest in the Philippines.
With due respect, I disagree.
My position remains the same as the one I expressed in my earlier column, “ICC Warrant vs.Sen. Bato: Our Duty as a Custodial State” (Pinoy Exposé, November 11, 2025).
Article 59 of the Rome Statute reflects a customary rule consistent with Article II, Section 2 of the Constitution.
Under Article 59, a person arrested pursuant to an ICC warrant must be brought promptly before a competent judicial authority of the custodial State. That local court must determine whether the warrant applies to the person arrested, whether the arrest followed due process, and whether the person’s rights were respected.
The history of Article 59 shows that it was patterned after Article 9 of the International Covenant on Civil and Political Rights, which guarantees judicial oversight over arrests. Similar safeguards were recognized after the Nuremberg and Tokyo War Crimes Trials and later, in the tribunals for Yugoslavia and Rwanda. International criminal justice has never meant justice without courts, procedure, or rights.
Republic Act No. 9851 itself recognizes international human rights principles and decisions of international tribunals as authoritative guides. Cooperation with international justice must therefore be read together with due process, not apart from it.
Dean Mel is correct: no one is above the law.
But this principle cuts both ways. No accused person, senator or ordinary citizen, may place himself beyond accountability.
At the same time, no warrant, foreign or international, may be enforced in a manner that bypasses the Constitution.
