The International Criminal Court investigation in the Philippines, or the situation in the Republic of the Philippines, is an ongoing investigation by the International Criminal Court (ICC) into alleged crimes against humanity committed during the Philippine drug war.
The Philippines announced its intention to withdraw from the Rome Statute on March 14, 2018, approximately one month after the ICC launched a preliminary investigation into the situation in the country. The withdrawal took effect on March 16, 2019. Since the Philippines is no longer a state party to the Rome Statute, the investigation covers only the period during which the treaty was in force in the country, between November 1, 2011, and March 16, 2019. In a 2021 ruling, the Supreme Court of the Philippines stated that the Philippines remains obligated to cooperate with ICC proceedings despite its withdrawal from the Rome Statute.
On March 11, 2025, former president Rodrigo Duterte was arrested by the Philippine National Police in coordination with Interpol following the issuance of an arrest warrant by the ICC. On April 23, 2026, ICC Pre-Trial Chamber I unanimously confirmed all charges against Duterte and committed him to trial before a Trial Chamber. The judges found substantial grounds to believe that Duterte was criminally responsible for crimes against humanity in connection with the Philippine drug war.
Background Davao Death Squad
The Davao Death Squad (DDS), a Davao City–based vigilante group linked to former president Rodrigo Duterte, is estimated to have killed at least a thousand people since the 1990s. According to Human Rights Watch, the group mostly targeted alleged drug dealers, petty criminals, and was involved in forced disappearances, summary executions, and drug dealing.
During an October 2016 Philippine Senate inquiry into extrajudicial killings, opposition Senator Leila de Lima presented a witness, Edgar Matobato, a self-confessed former member of the DDS; Matobato testified that the DDS was taking orders from Duterte and claimed that Duterte himself, while he was still mayor of Davao City, had killed a member of the Department of Justice with an Uzi submachine gun. Duterte dismissed Matobato's claims as a lie, and the Senate probe was terminated on October 13, 2016, for lack of evidence. Arturo Lascañas, a retired police officer who initially denied being a member of the group in the Senate hearing, retracted his statement a year later, backed up Matobato's accusations, and admitted to killing 200 people as a DDS member, claiming that they "were motivated by the reward system ... when a killing is ordered and there's a price".
Philippine drug war
A day after the 2016 presidential election, presidential forerunner Duterte said, "I will be a dictator [...] but only against forces of evil – criminality, drugs and corruption in government", and vowed that if he failed to fulfill his promise to end crime, corruption, and drugs within the first six months of his term, he would step down from the presidency. On July 1, the day after the inauguration of Duterte as president, the Philippine National Police (PNP) launched Project Double Barrel, marking the beginning of the Philippine drug war.
From his presidential campaign to the end of his presidency, President Duterte made multiple remarks to kill criminals and drug syndicates. He has also given law enforcers "shoot-to-kill" orders for criminals and drug syndicates, further assuring their protection from prosecution and saying he would go to jail in place of them.
By the end of Duterte's term, the number of drug suspects killed since Duterte took office was officially tallied by the Philippine government as 6,252. Human rights groups, including the ICC, however, claim drug casualties reached as high as 12,000 to 30,000 and the killings reached their peak between 2016 and 2017.
History On October 13, 2016, about four months into the Philippine drug war, ICC prosecutor Fatou Bensouda expressed deep concern over reports of extrajudicial killings of alleged drug dealers and users in the Philippines, stating that the ICC would be "closely following developments" in the country to assess whether to open a preliminary examination if necessary. The following month, on November 17, President Duterte threatened to follow Russia's lead by withdrawing the Philippines from the ICC, which he called "useless" in Filipino.
On April 27, 2017, Filipino lawyer Jude Sabio submitted a 77-page document to the ICC titled "The Situation of Mass Murder in the Philippines", requesting charges of mass murder and crimes against humanity against President Duterte and 11 other officials. Similarly, then-Senator Antonio Trillanes and members of the Magdalo Party-List, led by then-Representative Gary Alejano, filed a 45-page supplemental complaint requesting charges of crimes against humanity in addition to the earlier filing by Sabio. However, in January 2020, Sabio retracted his allegations and requested the ICC to dismiss the charges, claiming that his 2017 case was an orchestrated move by the Liberal Party, particularly Senators Antonio Trillanes and Leila de Lima, to discredit Duterte. The ICC rejected Sabio's request, stating that it "cannot effectively destroy or return information once it is in its possession or control".
On August 28, 2018, activists and families of eight victims of the Philippine drug war, led by the National Union of People's Lawyers, submitted a 50-page document to the ICC. This was followed up by two supplemental pleadings, filed in October 2018 and October 2019, respectively.
Inquiries on the drug war were held by the House of Representatives' Quad Committee and the Senate Blue Ribbon sub-committee in October 2024. Duterte attended the Senate inquiry and transcripts from the hearings was later submitted to the ICC by Duterte's staunch critic, former Senator Antonio Trillanes.
Arrest of Rodrigo Duterte
On March 11, 2025, Rodrigo Duterte was arrested by the Philippine National Police through the Interpol at Ninoy Aquino International Airport upon his arrival from Hong Kong, following the issuance of an arrest warrant by the ICC on charges of crimes against humanity.
Arrest warrant against Ronald dela Rosa
On May 11, 2026, Senator Ronald dela Rosa resurfaced at the Senate of the Philippines after months of absence amid reports of an impending arrest by the International Criminal Court (ICC). Dela Rosa returned to participate in the election of the Senate President, where Senator Alan Peter Cayetano successfully ousted incumbent Senate President Tito Sotto.
Earlier that day, agents of the National Bureau of Investigation (NBI), accompanied by former senator Antonio Trillanes, reportedly attempted to serve an ICC arrest warrant against dela Rosa inside the Senate premises. CCTV footage later released by the Senate showed dela Rosa running through Senate corridors while being pursued by law enforcement agents. The Senate was subsequently placed under lockdown and dela Rosa was placed under Senate protective custody by the Office of the Sergeant-at-Arms upon the orders of newly elected Senate President Cayetano.
Later that evening, the ICC officially confirmed that Pre-Trial Chamber I had unsealed an arrest warrant against dela Rosa that had originally been issued under seal on November 6, 2025. The warrant charged dela Rosa as an "indirect co-perpetrator" of the alleged crime against humanity of murder in relation to killings committed during the Philippine drug war between July 3, 2016 and April 30, 2018, when he served as Chief of the Philippine National Police. The Chamber stated that there were reasonable grounds to believe that dela Rosa contributed to a widespread and systematic attack against civilians pursuant to a state policy targeting alleged drug offenders.
Following the unsealing of the warrant, human rights organisations including Human Rights Watch and Amnesty International Philippines called on the Philippine government to immediately arrest and surrender dela Rosa to the ICC.
Jurisdiction The Philippines signed the Rome Statute of the International Criminal Court (ICC) on December 28, 2000, and ratified it on August 30, 2011. The treaty came into force in the country on November 1, 2011. On March 14, 2018, a month after the ICC opened a preliminary investigation into the situation in the Philippines, President Duterte said in a statement that "the Philippines is withdrawing its ratification of the Rome statute effective immediately". Duterte rebuked the idea of permitting foreigners to interfere in the country's justice system and his administration emphasized that cases against him should be filed before the national courts; additionally, he argued that the Rome Statute, which was ratified by the Senate in 2011, was never binding in the Philippines as it was never published in the Official Gazette, a requirement for a law in the country to take effect. However, in accordance with article 127 (1) of the treaty, the withdrawal shall only take effect "one year after the date of receipt of the notification". Two days later, on March 16, the Philippines formally notified the secretary-general of the United Nations of its decision to withdraw from the Rome Statute. The country officially left the ICC one year later, on March 17, 2019.
The jurisdiction of the ICC investigation in the Philippines will be limited to the period when the country was a state party to the Rome Statute, between November 1, 2011, and March 16, 2019, encompassing almost three years of Duterte's presidency, during which the Philippine drug war was at its height. The Philippine Supreme Court, in a 2021 ruling, commented on the withdrawal from the Rome Statute and stated that the Philippines still has an obligation to cooperate in the ICC proceedings.
The administration of president Bongbong Marcos, which succeeded Duterte in June 2022, maintained that the ICC has no jurisdiction in the Philippines. He argued that the Philippines has a working justice system and hence does not warrant a probe by the ICC. This is despite the ICC meant to be complementary to domestic court systems and only prosecute cases only if "when States do not or are unwilling or unable to do" Regardless, the government has allowed the ICC to conduct its investigation in the Philippines independently. Marcos stated the PNP acted on behalf on Interpol, which the Philippines is a member of, leading to Rodrigo Duterte's arrest in March 2025.
In October 2024, former Senator Leila de Lima said that there is no legal obstacle to prevent the Philippine government's cooperation with the ICC citing Republic Act 9851 or the "Philippine Act on Crimes Against International Humanitarian Law, Genocide, and Other Crimes Against Humanity" including the surrender or extradition of accused persons "to the appropriate international court". The 2009 law came into effect two years before the Philippines ratified the Rome Statute.
Investigation On September 15, 2021, the ICC's Pre-Trial Chamber I authorized the prosecutor of the International Criminal Court to open an investigation of crimes within the court's jurisdiction in the Philippines, spanning between November 1, 2011, and March 16, 2019, before the Philippines withdrew from the ICC.
In the same month, the government of the Philippines announced that it would not cooperate with the ICC on their investigation and would bar their investigators from entering the country. However, by 2024, the government under the succeeding Bongbong Marcos administration stated that it could not prevent investigators from acting independently, despite the state's continued non-cooperation.
