Two U.S. advocacy organizations have filed a federal lawsuit against the Trump administration, arguing that sanctions imposed on the International Criminal Court (ICC) violate constitutional free speech protections and unlawfully restrict Americans from engaging with the Hague based tribunal.
The legal challenge comes as the administration intensifies its campaign against the ICC, pledging broader sanctions and diplomatic efforts to curb the court’s influence. The move has drawn criticism from European allies, who have reaffirmed their support for the court and its role in international justice.
Lawsuit challenges Trump’s executive order
The lawsuit, filed in federal court in New York by Democracy for the Arab World Now (DAWN) and the Taxpayer Alliance Against Genocide, seeks to block President Donald Trump’s February 2025 executive order that authorized sanctions against ICC officials.
Under the order, the United States has imposed sanctions on ICC judges, prosecutors, and Palestinian human rights groups that supported investigations into allegations that the United States and Israel committed war crimes during the Gaza conflict.

The plaintiffs argue that the executive order effectively criminalizes legitimate advocacy and legal cooperation with the court, violating First Amendment protections.
According to the complaint reviewed by Reuters, the organizations have avoided submitting evidence to the ICC or coordinating with sanctioned individuals, including United Nations Special Rapporteur Francesca Albanese, out of concern they could face financial penalties or criminal prosecution.
“The Trump administration is using the blunt instrument of economic sanctions not only to punish human rights defenders but to police the political expression of millions of Americans,” DAWN Executive Director Omar Shakir said.
Longstanding U.S. opposition to the ICC
Successive U.S. administrations have objected to the ICC’s claim of jurisdiction over American citizens, particularly military personnel.
Trump first imposed sanctions on ICC officials during his first presidential term after the court opened an investigation into possible war crimes committed in Afghanistan, including allegations involving U.S. forces.
That 2020 executive order was later blocked by a federal judge, who found it was likely unconstitutional because it infringed on free speech rights. The sanctions were subsequently revoked by President Joe Biden in 2021.
The current legal challenge argues that Trump’s latest sanctions repeat many of the same constitutional problems identified by the courts several years ago.
Renewed dispute over Gaza investigation
The latest confrontation follows the ICC’s decision to issue an arrest warrant last year for Israeli Prime Minister Benjamin Netanyahu, prompting renewed efforts by Washington to penalize the court.
While ICC prosecutors initially investigated alleged crimes involving U.S. forces in Afghanistan in 2020, the court shifted its focus in 2021 toward alleged crimes committed by the Taliban and the former Afghan government.
The ICC has not pursued investigations targeting U.S. personnel in recent years.
Europe backs the court
The Trump administration’s renewed campaign has received little support from European partners.
The European Union reaffirmed this week that it fully supports the ICC and its mission to combat impunity for serious international crimes.
European Commission spokesperson Anouar El Anouni said threats or attacks against the court, its personnel, or those cooperating with it were unacceptable, adding that the ICC does not threaten the sovereignty of states.
The Dutch Foreign Ministry also expressed concern over Washington’s increasingly confrontational rhetoric, stating that independent international courts must be allowed to carry out their mandates without interference.
Why it matters
The case could become an important constitutional test of how far the U.S. government can use sanctions to restrict engagement with international institutions.
If the court rules in favor of the advocacy groups, it may limit the administration’s ability to sanction individuals and organizations involved with the ICC on free speech grounds. A ruling upholding the executive order, however, could strengthen presidential authority to use sanctions against international legal bodies and those who cooperate with them.
Analysis
The lawsuit reflects a broader clash between national sovereignty and international accountability. Washington has consistently rejected the ICC’s jurisdiction over U.S. citizens, arguing that American courts are fully capable of handling allegations against their own personnel. At the same time, critics contend that sanctions targeting lawyers, researchers, and advocacy organizations risk extending government power beyond foreign policy into constitutionally protected political expression.
Beyond its legal implications, the dispute highlights growing transatlantic divisions over international justice. While the United States views the ICC as exceeding its mandate, European governments continue to regard the court as a cornerstone of the rules based international order. The outcome of the case could therefore influence not only U.S. constitutional law but also Washington’s future relationship with international judicial institutions and its allies.
