A deepening confrontation between the United States and the International Criminal Court (ICC) has raised fresh concerns about the future of international criminal justice, following Washington's decision to impose sanctions against the court as an institution.

United Nations Secretary-General António Guterres condemned the move, warning that measures targeting the court could undermine its independence and ability to investigate and prosecute some of the world's gravest crimes.

The dispute intensified after US Secretary of State Marco Rubio threatened to dismantle the institution unless it ended what Washington described as threats against American citizens.

Speaking to journalists on Friday, October 9, 2026, UN spokesperson Stéphane Dujarric said Guterres was deeply concerned about the implications of the sanctions for the court's operations.

The Secretary-General described the measures as “a serious blow to our collective pursuit of international criminal justice, of which the ICC is a key pillar”.

The development has brought competing positions on national sovereignty, international legal authority and accountability for alleged war crimes and other serious violations into sharper focus.

UN Warns Sanctions Could Undermine International Justice

Guterres expressed concern that the sanctions could interfere with the ICC's ability to carry out its responsibilities under international law.

Through his spokesperson, the UN chief reaffirmed his support for the independence of the court and its officials, urging governments to honour their international legal commitments.

He also reiterated the United Nations' commitment to cooperating with the ICC under the relationship agreement approved by the UN General Assembly on September 13, 2004.

Although the ICC is an independent judicial institution rather than a UN organ, the two organisations cooperate on matters connected to international criminal accountability.

The court was established under the Rome Statute to prosecute individuals accused of genocide, crimes against humanity, war crimes and the crime of aggression, subject to its jurisdictional requirements.

Its mandate is particularly significant in situations where national authorities are unwilling or unable genuinely to investigate and prosecute crimes falling within its jurisdiction.

The UN's concerns reflect the potential consequences of measures that could restrict the court's access to financial services, institutional resources and international cooperation.

Washington Accuses ICC of Threatening American Interests

The United States defended its position, with Secretary of State Marco Rubio delivering an unusually forceful warning against the court.

Rubio said Washington intended to restrict transactions involving the institution as part of efforts to weaken its operations.

“We will ban transactions with this rogue court, cutting off their resources and crippling its ability to operate,” he declared.

He emphasised that the United States had never become a party to the Rome Statute and rejected the court's authority over American citizens.

“America never joined the court. We don’t need it. And we don’t want it,” Rubio said.

The Secretary of State maintained that diplomatic engagement remained possible but warned that Washington would intensify its response if the ICC continued activities the US government considered unacceptable.

“Either the ICC will end its threats, or we will end the ICC,” he stated.

Rubio also called on American allies to restrain the court, signalling that Washington expected other governments to take its objections seriously.

The US position centres on its rejection of ICC authority over its nationals without American consent.

However, the court's jurisdiction is not determined solely by whether an accused person's country of nationality has joined the Rome Statute. In certain circumstances, jurisdiction may also arise from the territory where alleged crimes occurred or from a referral by the UN Security Council.

This distinction lies at the heart of longstanding disagreements between Washington and the court over the reach of international criminal jurisdiction.

ICC Rejects Sanctions, Vows to Continue Investigations

The ICC condemned the new sanctions, describing them as an unprecedented escalation of American pressure against the institution.

The latest measures follow earlier US sanctions targeting 13 of the court's judges and prosecutors.

Unlike those previous restrictions, the new sanctions target the court itself, potentially disrupting its access to financial services, technology and other resources required for its operations.

The court described the decision as “an assault on the rule of law and on the very foundations of the international legal order”.

It accused Washington of attempting to disrupt judicial proceedings and intimidate individuals who work for or cooperate with the institution.

ICC President Tomoko Akane insisted that the court would not abandon its responsibilities.

“The court will continue to fully discharge its mandate, with independence and impartiality, acting only on the basis of the law and the evidence for the sake of the countless victims of grave crimes,” she said.

Her remarks underscored the court's position that judicial decisions must be guided by applicable law and evidence rather than political pressure.

Court Appeals to Member States for Support

Despite its determination to continue operating, the ICC acknowledged that its future would depend partly on the response of governments that established it.

“Its fate now rests also in the hands of the states that created it,” the court stated.

It warned that the commitments contained in the Rome Statute would remain meaningful only if member states demonstrated the political and institutional resolve to uphold them.

The ICC has 125 states parties, including 33 African countries, according to its official membership records.

These governments have responsibilities under the Rome Statute, including cooperation with the court in accordance with the treaty.

The sanctions could create additional difficulties for institutions, organisations and service providers that maintain financial or operational relationships with the ICC.

Reports on the measures indicate that US-linked transactions with the court face significant restrictions, although a transition period has been provided for certain activities.

The ICC appealed for international solidarity, warning against punishing individuals for carrying out judicial responsibilities.

“No one should be punished for serving the cause of justice. History will judge this moment,” the court declared.

UN Human Rights Experts Warn of Consequences for Victims

Independent human rights experts appointed by the United Nations Human Rights Council also criticised Washington's decision.

They described the sanctions as a deliberate attempt to weaken an international accountability system established to address the gravest crimes.

“Sanctioning the institution entrusted with delivering justice for the gravest international crimes is an assault on the foundations of international accountability and rule of law,” the experts said.

They urged governments committed to international justice to defend the court's independence.

The experts further warned that restrictions targeting the ICC could affect victims of atrocities who depend on international judicial mechanisms for accountability and possible reparations.

Their concerns extend beyond the institution's administrative operations.

For victims of war crimes, crimes against humanity and other serious offences, delays or disruptions to investigations may affect opportunities to present evidence, participate in proceedings and seek justice.

The experts maintained that governments should not attempt to avoid legal scrutiny through intimidation or pressure against judicial institutions.

Why the United States Opposes the ICC

The confrontation reflects a longstanding disagreement over the ICC's jurisdiction and the relationship between international criminal justice and national sovereignty.

The United States is not a party to the Rome Statute, the treaty establishing the court.

Washington has consistently challenged aspects of the ICC's authority, particularly where investigations or proceedings involve American personnel or officials of allied countries.

The Trump administration's latest measures represent a significant escalation because they target the institution as a whole rather than only particular officials.

The dispute also concerns ICC proceedings involving Israeli officials and investigations into alleged crimes connected to US personnel.

The ICC maintains that its jurisdiction is established by the Rome Statute and can, under specified circumstances, extend to nationals of countries that have not joined the treaty.

The legal distinction is important.

For certain crimes, the court may exercise jurisdiction when alleged conduct occurred on the territory of a state party, even if the accused person is a national of a non-member country. A UN Security Council referral can also establish jurisdiction in specified circumstances.

Washington's rejection of the court's authority therefore does not, by itself, resolve the legal questions surrounding the ICC's jurisdiction.

What the Dispute Means for Africa

The confrontation carries particular significance for African countries, many of which are parties to the Rome Statute.

The ICC has been involved in proceedings concerning alleged atrocities in several African states, while its relationship with African governments has also generated debate over sovereignty, fairness and the application of international justice.

For communities affected by armed conflict and mass violence, accountability mechanisms can offer avenues for addressing crimes that domestic institutions may struggle to prosecute.

However, international criminal justice also depends heavily on cooperation from national governments.

The ICC does not possess its own police force and relies on states to execute arrest warrants and assist investigations.

Restrictions affecting the court's resources or operations could therefore complicate proceedings involving victims and witnesses across different regions.

The implications are not confined to Africa. They extend to situations involving alleged atrocities elsewhere and to the broader question of whether international judicial institutions can operate independently when powerful governments oppose their decisions.

International Community Faces a Test of Commitment

The sanctions have drawn criticism from several US allies, including European governments, which have reaffirmed their support for the ICC.

The European Commission and a number of national governments have expressed concern about the consequences for international law and judicial independence.

The dispute now presents governments with difficult diplomatic and legal questions.

States supporting the ICC must consider how to protect its operations while managing relationships with Washington.

The United States, meanwhile, has indicated that diplomatic discussions remain possible, but its stated objective is to prevent the court from exercising authority it considers unacceptable.

The immediate questions concern how the sanctions will be implemented, which services will be affected and whether member states can develop arrangements to maintain the court's operations.

For victims awaiting justice, the consequences could be more direct.

The ICC's ability to investigate allegations, protect witnesses, conduct trials and support victims depends on resources and cooperation that political disputes can place under strain.

As the confrontation deepens, the central issue is whether disagreements over jurisdiction and sovereignty can be addressed without undermining the functioning of an international court established to prosecute the gravest crimes.

The United Nations has made its position clear: protecting the ICC's independence remains essential to the wider pursuit of international criminal accountability.
