Manila: The International Criminal Court (ICC) confirmed on Monday night that the warrant of arrest against Sen. Ronald 'Bato' dela Rosa, which circulated in the media, 'is indeed a formal ICC document.' The ICC unsealed and formally classified the document as 'public' on May 11. According to Philippines News Agency, the arrest warrant was initially issued confidentially under seal by Pre-Trial Chamber I of the ICC on November 6, 2025. ICC spokesperson Oriane Maillet communicated this via a text message to reporters. Dela Rosa, who had not appeared in public since November, was present at a Senate session on Monday, where he cast a vote to oust Senate President Vicente Sotto III during a leadership change in the chamber. On the same day, former senator Antonio Trillanes IV, alongside National Bureau of Investigation (NBI) personnel, presented to the media what he claimed was a copy of the ICC arrest warrant. The document was issued on November 6 by the ICC Pre-Trial Chamber against dela Rosa for his alleged criminal responsibility as an 'indirect co-perpetrator' in the killings that occurred during the anti-illegal drugs campaign in the Philippines. The ICC prosecution previously stated that detained former president Rodrigo Duterte and his eight alleged co-perpetrators, including dela Rosa, 'shared a common plan or agreement to neutralize alleged criminals in the Philippines,' particularly those associated with drug use and sale through violent crimes, including murder. The ICC Pre-Trial Chamber I, in the unsealed warrant, noted that dela Rosa's alleged involvement in the 'common plan' constitutes a 'crime against humanity of murder' committed at least between July 3, 2016, and the end of April 2018 in the Philippines, during which no fewer than 32 individuals were killed. Dela Rosa served as Duterte's first Philippine National Police chief during his presidency.
