ICC Duterte Case Timeline and Victim Participation

The proceedings against former Philippine President Rodrigo Roa Duterte did not begin with his arrest. Before a formal investigation was opened, individuals, families of victims and civil-society organisations had submitted information to the Office of the Prosecutor. When the Prosecutor later sought judicial authorisation to investigate, victims used a different procedure to present their views and concerns directly to the Pre-Trial Chamber. Those actions—and participation in the subsequent case—perform distinct legal functions.

As at 3 August 2026, Pre-Trial Chamber I had confirmed three counts of crimes against humanity of murder and attempted murder and committed the case to Trial Chamber III. The trial was scheduled to open on 30 November 2026. Confirmation of charges is not a conviction. Mr Duterte remains presumed innocent. This article uses official ICC materials to trace the proceedings while separating submitters’ allegations, victims’ representations, prosecutorial positions and judicial findings.

Where the case stands

The case is formally titled The Prosecutor v. Rodrigo Roa Duterte, ICC-01/21-01/25. It arises from the Situation in the Republic of the Philippines, ICC-01/21. The Court’s June 2026 case information sheet records that the confirmation hearing took place from 23 to 27 February 2026. On 23 April, Pre-Trial Chamber I unanimously confirmed three charges and committed Mr Duterte to trial.

The confirmed allegations concern murders in or around Davao City during the mayoral period said to have been committed by the Davao Death Squad; murders of so-called High-Value Targets during the presidential period; and murders and attempted murders in barangay clearance operations during the presidential period. The public redacted decision confirms 49 incidents involving at least 78 victims: at least 19 under Count 1, at least 14 under Count 2, and at least 45 under Count 3 (43 murders and two attempted murders). These are charges permitted to proceed to trial, not proven facts.

Three distinct routes into the ICC process

Public discussion often treats every submission to the ICC as victim participation. At least three legal routes must be distinguished:

Article 15 communications: individuals or organisations may provide the Prosecutor with information about possible crimes within the Court’s jurisdiction. The 2017 communication by Jude Sabio, the supplemental communication by Antonio Trillanes IV and Gary Alejano, and the 2018 communication by Rise Up for Life and for Rights and family members were external submissions. Their contents are the submitters’ allegations, not ICC findings.
Article 15(3) representations: when the Prosecutor seeks authorisation to investigate on his or her own initiative, victims may present views and concerns to the Pre-Trial Chamber. This is a submission to judges; it does not itself confer participating-victim status in a later case.
Victim participation in a case: once proceedings exist against a particular suspect, victims must be admitted under the applicable rules and Chamber orders. They then participate at stages and in modalities determined by the Court, usually through legal representatives.

The routes are related but not interchangeable. Communications provide information; representations assist judges considering whether to authorise an investigation; case participation enables victims to present views and concerns within defined judicial proceedings.

How victim representations informed the authorisation decision

The 2021 article 15(3) process created an important entry point before a formal investigation began. Victims could tell the judges whether they wanted an investigation and identify concerns about the crimes, locations and time periods that should be considered. The Victims Participation and Reparations Section (VPRS) collected and transmitted their representations.

The authorisation decision records that the Registry assessed representations covering 1,530 individual victims and 1,050 families. Ninety-four per cent supported an investigation. The reasons included the wish for a genuine investigation by an impartial international court, accountability, an end to impunity, prevention, truth, correction of false accusations against those killed and an opportunity for victims’ voices to be heard.

The Chamber stated that the representations corresponded “to a great extent” with the Prosecution’s submissions and supporting material and referred to them in the relevant parts of its analysis. That demonstrates that victim input entered the judicial reasoning. It does not mean that every allegation was accepted or that anyone’s criminal responsibility was determined in advance.

Withdrawal, deferral and resumption

The Philippines notified its withdrawal from the Rome Statute on 17 March 2018, effective one year later. The ICC maintains jurisdiction over alleged crimes committed while the Philippines was a State Party. On 22 April 2026, the Appeals Chamber majority upheld the jurisdiction ruling, finding that a preliminary examination can constitute a “matter under consideration” for article 127(2). Judge Lordkipanidze attached a partly dissenting opinion.

Jurisdiction alone does not make proceedings automatic. In 2021, the Philippines requested deferral under article 18(2), maintaining that domestic authorities should act, and ICC investigative activities were suspended. Pre-Trial Chamber I authorised resumption in January 2023, and the Appeals Chamber upheld that decision in July. For victims, complementarity was not merely an abstract doctrine: it affected whether investigation continued, when information became available and how long accountability would take.

From arrest warrant to confirmation of charges

On 10 February 2025, the Prosecution sought a warrant for crimes against humanity of murder, torture and rape. The warrant actually issued by the Chamber was based on the crime against humanity of murder. The application and the judicial warrant must not be conflated. The warrant was issued as Secret on 7 March and reclassified as Public on 11 March. Philippine authorities arrested Mr Duterte, who was surrendered to the ICC on 12 March.

An arrest warrant applies a reasonable-grounds-to-believe standard. Confirmation of charges requires substantial grounds to believe. On 23 April 2026, the Chamber confirmed three counts of crimes against humanity of murder and attempted murder. That allowed the case to proceed to trial; it did not establish guilt beyond reasonable doubt.

The decision also addressed an issue linking the representation of victimisation with defence rights. The Prosecution maintained that the 49 incidents and 78 victims listed in its charging documents were non-exhaustive examples. The Office of Public Counsel for Victims argued that this approach better reflected the scale of victimisation. The Defence submitted that the Prosecution still had to meet the confirmation threshold for the listed incidents and provide sufficiently specific notice.

The Chamber accepted that large-scale criminality may be charged through representative incidents within defined temporal and geographical parameters and identifiable groups of perpetrators and victims. The stated numbers do not necessarily operate as final upper or lower limits. This does not permit the Prosecution to add unrelated historical events at trial: further particulars must remain within the facts and circumstances of the confirmed charges, adequate notice must be given, and amendments remain governed by article 61(9). The approach therefore seeks to recognise the scale of alleged victimisation while preserving fair-trial requirements.

The procedural position of 539 participating victims

Paragraph 12 and footnotes 26–27 of the confirmation decision identify two decisions of 26 January and 13 February 2026—ICC-01/21-01/25-358 and ICC-01/21-01/25-375—which authorised 539 victims to participate in the confirmation proceedings and appointed common legal representatives. The Court’s June 2026 case information sheet further identifies Joel Butuyan, Gilbert Andres and Paolina Massidda of the Office of Public Counsel for Victims as a single team.

Common representation enables a large group to enter a complex international proceeding through qualified counsel. It should not be taken to mean that all 539 people have identical experiences or views. Consultation, communication with affected communities, the expression of different forms of harm, and protection and confidentiality measures will remain central to whether participation is meaningful.

Victims are not a second prosecution. The Prosecution investigates and presents the case. Participating victims may present views and concerns where their personal interests are affected and within the modalities set by the Chamber. The Court must also protect defence rights and the fairness and impartiality of the trial.

What cannot yet be concluded

First, Mr Duterte has not been convicted. Reporting and advocacy must not describe confirmed charges as proven crimes.

Second, the case has not entered reparations proceedings. Although articles 75 and 79 of the Rome Statute establish a reparations framework and the Trust Fund for Victims, any discussion of reparations in this case remains prospective.

Third, participation figures alone do not establish meaningful participation. Assessment requires continued attention to legal representation, field communication, access to information, protection measures and the way the Trial Chamber addresses concrete victim submissions.

Questions for Taiwan

The Duterte case illustrates that victim-centred justice does not mean presuming the accused guilty. It asks whether victims can safely and knowledgeably articulate affected interests with legal assistance while the presumption of innocence and fair-trial guarantees remain intact.

The ICC model cannot simply be transplanted into Taiwan, but it raises useful questions. Can affected people provide information through a trusted channel before a major case is formally constituted? Can victims express views before decisions affecting their interests and understand how a court addresses them? Where participation involves large and diverse groups, how can common representation reconcile efficiency, difference and trust?

The trial phase will test not only whether the Prosecution can prove the charges, but whether the ICC can sustain its institutional commitment to victims’ rights in a lengthy, transnational and highly politicised proceeding.
