Rationale for Arresting Rodrigo Duterte

Rodrigo Duterte’s arrest can be justified under a dual framework of Philippine domestic law and international legal obligations, despite the Philippines’ withdrawal from the ICC in 2019. His actions during his tenure as mayor of Davao City and as President of the Philippines from 2016 to 2022—particularly the orchestration of extrajudicial killings in the “war on drugs”—provide a basis for accountability under both jurisdictions.

Philippine Constitutional and Legal Basis

 1. 1987 Philippine Constitution, Article III (Bill of Rights), Section 1 – Due Process and Right to LifeThe Philippine Constitution guarantees that “no person shall be deprived of life, liberty, or property without due process of law.” The “war on drugs” under Duterte resulted in thousands of deaths—official police figures cite over 6,000, while human rights groups estimate up to 30,000—many without judicial oversight or trial. Evidence from investigations, such as Amnesty International’s reports of police executing suspects and planting evidence, suggests systematic violations of this right. Duterte’s public admissions, like his 2016 statement, “I’d kill you” to drug pushers, and his 2024 Senate testimony claiming responsibility for a Davao “death squad,” indicate he may have directed or condoned these acts, implicating him in breaches of constitutional protections.

 2. Article II, Section 11 – State Values Human Dignity

The Constitution mandates that the State “values the dignity of every human person and guarantees full respect for human rights.” The widespread extrajudicial killings, targeting mostly impoverished urban men and including minors like Kian delos Santos (killed in 2017), contradict this principle. Duterte’s policies, which he defended unapologetically in October 2024 before the Senate, arguably undermined human dignity, providing grounds for local accountability.

 3. Republic Act No. 9851 (Philippine Act on Crimes Against International Humanitarian Law, Genocide, and Other Crimes Against Humanity)

Enacted in 2009, RA 9851 domesticates international crimes, including “murder” as a crime against humanity when committed as part of a “widespread or systematic attack directed against any civilian population.” The scale and pattern of killings during Duterte’s drug war—documented by groups like Human Rights Watch as involving police raids without warrants and staged “self-defense” scenarios—fit this definition. Section 6 of RA 9851 holds superiors criminally liable if they “knew or should have known” about such acts and failed to prevent them. Duterte’s explicit orders and failure to investigate or prosecute these killings suggest command responsibility, justifying arrest under Philippine law.

 4. Presidential Immunity LimitationUnder Philippine jurisprudence (e.g., Estrada v. Desierto, 2001), presidential immunity from suit applies only during incumbency. Duterte, no longer president since 2022, lost this shield, making him subject to arrest for acts committed in office, as affirmed by his detention on March 11, 2025, at Manila’s airport.

International Constitutional and Legal Basis

 1. Rome Statute of the ICC, Article 7 – Crimes Against HumanityThe ICC, under Article 7(1)(a), defines “murder” as a crime against humanity when part of a widespread or systematic attack against civilians. The ICC’s Pre-Trial Chamber I, in its March 7, 2025, warrant, found “reasonable grounds” to believe Duterte was responsible for such murders between November 1, 2011, and March 16, 2019, spanning his time as Davao mayor and president. The ICC cites the Davao Death Squad (DDS) and nationwide drug war killings—estimated at 12,000 to 30,000 by ICC prosecutors—as evidence of a deliberate policy. Duterte’s role as an “indirect co-perpetrator” aligns with Article 25(3)(a), justifying his arrest and transfer to The Hague on March 12, 2025.

 2. Article 27 – Irrelevance of Official CapacityThe Rome Statute removes immunity for heads of state, stating that official capacity “shall in no case exempt a person from criminal responsibility.” Duterte’s former presidency offers no defense, supporting the ICC’s authority to pursue him despite his past office.

 3. Jurisdiction Despite Withdrawal (Article 127)The Philippines withdrew from the ICC effective March 17, 2019, but Article 127(1) preserves jurisdiction over crimes committed while a state was a member (until March 16, 2019). Many of Duterte’s alleged crimes, including those from 2016 to 2019, fall within this period. The ICC’s judges confirmed this in the arrest warrant, countering claims by Duterte’s allies (e.g., Salvador Panelo) that the arrest lacks jurisdiction. His arrest via Interpol cooperation further aligns with international law enforcement obligations.

 4. Universal Jurisdiction and State CooperationUnder customary international law, crimes against humanity invoke universal jurisdiction, obliging states to act against perpetrators. The Philippines, despite its ICC exit, cooperated with Interpol on March 11, 2025, as President Marcos Jr. noted, fulfilling commitments to international police networks. This reflects a practical obligation to address atrocities, even absent ICC membership.

Synthesis and Conclusion

Locally, Duterte’s arrest is warranted under the Philippine Constitution and RA 9851 for violating due process, human dignity, and domestic laws against crimes against humanity, especially given his loss of immunity. Internationally, the ICC’s Rome Statute provides a robust basis through its jurisdiction over pre-withdrawal crimes, rejection of immunity, and evidence of systematic murder. His arrest on March 11, 2025, and transfer to The Hague on March 12, 2025, bridge these frameworks, reflecting both national accountability demands (e.g., from victims’ families) and global justice imperatives. The bell tolls not just for the thousands killed, but for a legal reckoning Duterte can no longer evade.
