MANILA — The political confrontation between Philippine Vice President Sara Duterte and President Ferdinand Marcos Jr.’s administration has intensified after authorities served an arrest warrant in a grave-threats case, followed by a public dispute over how the warrant was handled.

Duterte posted bail on September 5 after a Quezon City court issued the warrant over three counts of alleged grave threats involving President Marcos, First Lady Liza Araneta-Marcos and former House Speaker Martin Romualdez. On September 7, Interior Secretary Jonvic Remulla said Duterte’s camp had initially sought to be detained but later chose to proceed directly to court and post bail.

Arrest Warrant Escalates Political Conflict

The criminal case stems from remarks Duterte made during an online press briefing in November 2024.

Prosecutors allege that she spoke about arranging the killing of Marcos, his wife and Romualdez if she herself were killed. Duterte has disputed the allegations and says the legal proceedings are politically motivated. The Quezon City court set bail at 120,000 pesos for each of the three charges.

The case has become another major front in the increasingly bitter split between the Marcos and Duterte political families.

Duterte Posts Bail

Duterte appeared voluntarily before the Quezon City court on September 5 and posted a combined 360,000 pesos in bail.

Her lawyers said she had no intention of evading the legal process and would continue using available legal remedies. Duterte also raised concerns about her personal safety and accused authorities of harassment, while government officials rejected the suggestion that police action was intended to harm her.

Because she voluntarily appeared and posted bail, she was not held in prolonged detention.

Government Rejects Harassment Allegations

The dispute has continued beyond the courtroom.

Duterte has said she no longer feels safe and has complained about police surveillance and harassment. The Department of the Interior and Local Government has rejected those allegations, while officials insist that law-enforcement agencies are acting within legal procedures.

Remulla also accused Duterte’s camp of initially seeking a highly public detention scenario before changing course and opting for bail. Duterte’s representatives have disputed aspects of the government’s characterization of the events.

Impeachment Trial Adds to the Pressure

The criminal case is only one part of Duterte’s broader legal and political difficulties.

She is also facing an impeachment proceeding in the Philippine Senate following her impeachment by the House of Representatives. The allegations include accusations related to public funds as well as the threats case, all of which Duterte has denied.

A conviction in the impeachment process could remove her from office and have major consequences for her political future.

The proceedings are therefore being closely watched because Duterte has been positioning herself as a potential candidate for the 2028 presidential election.

Marcos-Duterte Alliance Has Collapsed

The confrontation is particularly significant because Marcos and Duterte were once political allies.

They campaigned together in the 2022 election and won the presidency and vice presidency by a large margin. Their relationship subsequently deteriorated, producing disputes over policy, political influence and allegations of corruption.

The breakdown between the two families has transformed Philippine politics and created competing power centers ahead of the next presidential election.

Duterte Denies the Allegations

Duterte maintains that the accusations against her are being used for political purposes.

Her legal team has challenged aspects of the prosecution and has argued that issues connected to the impeachment process should not simultaneously be pursued through criminal proceedings. Government officials have rejected that interpretation and said the criminal case can proceed independently.

The courts will ultimately determine the legal questions surrounding the charges.

Why the Case Matters for 2028

The dispute could have consequences far beyond Duterte’s current position as vice president.

If she remains politically eligible, Duterte could emerge as a major contender in the 2028 presidential race. But an adverse outcome in her impeachment proceedings could remove her from office and potentially prevent her from holding public office in the future.

That makes the current legal battles important not only for the present administration but also for the Philippines’ next political cycle.

A Major Test for Philippine Politics

The developments underline the extraordinary political tensions surrounding two of the country’s most powerful political families.

For Marcos, the government’s handling of the Duterte cases is likely to remain under intense scrutiny. For Duterte, the criminal case and impeachment proceedings represent significant obstacles to maintaining political influence.

The immediate criminal case will now move through the Philippine judicial system after Duterte’s release on bail.

But the wider political conflict is unlikely to end there.

With the 2028 presidential contest already influencing political calculations, the struggle between the Marcos and Duterte camps could remain one of the defining stories of Philippine politics for years to come.
