Amelia DaviesOn 9 October 2026, the United States imposed sweeping sanctions on the International Criminal Court as an institution — blocking its US-held assets, barring American entities from doing business with it, and freezing the accounts of thirteen judges and prosecutors. Secretary of State Marco Rubio vowed to dismantle the court "brick by brick." The UK government responded within hours: a Downing Street spokesperson confirmed that Britain would not follow Washington, reaffirming its commitment to ICC independence. That distinction matters — but it does not fully protect UK entities working in international law.
What the US Sanctions Actually Prohibit
The US Treasury Department's Office of Foreign Assets Control (OFAC) has formally designated the International Criminal Court as a sanctioned entity. The immediate practical effect is that US persons and businesses — including US banks — are prohibited from providing funds, goods, or services to the court without a specific OFAC licence.
What makes this escalation more significant than the earlier targeted designations against individual judges is the inclusion of secondary exposure risk. Non-US suppliers, legal professionals, and funding organisations that maintain active relationships with the ICC may find themselves restricted from accessing the US financial system or penalised if they have US counterparties. A UK charity that processes a donation through a US correspondent bank, or a British barristers' chambers that holds a dollar-denominated client account, enters legally uncertain territory.
The OFAC designation allows a 180-day transition window — during which some operations may continue while ICC member states are invited to address Washington's objections. Officially, this is framed as an opportunity for negotiation. In practice, legal advisers are warning that 180 days is a short period in which to restructure longstanding institutional relationships, and that the language of the designation is deliberately broad, according to statements reported by Al Jazeera on 9 October 2026.
The ICC's own response was uncompromising. "Our work will continue across all our situations, our investigations and our prosecutions," said Deputy Prosecutor Nazhat Shameem Khan. The same day, former ICC judge Navi Pillay was awarded the Nobel Peace Prize — a pointed symbolic contrast that underlined how isolated Washington's position is within the international legal community.
The UK's Position: Principled, but Not a Legal Shield
The United Kingdom is a founding signatory to the Rome Statute and passed the International Criminal Court Act 2001 to implement its domestic obligations. Under that Act, UK authorities are legally required to cooperate with ICC requests — including, in principle, executing arrest warrants if an indicted individual enters British territory. This has already been tested in relation to the ICC's outstanding warrants for Vladimir Putin and former Israeli Prime Minister Benjamin Netanyahu, both issued in 2023 and 2024 respectively.
Prime Minister Starmer's government has confirmed it will not sanction ICC officials, nor will it follow the US in blocking the court's operations. For the purposes of UK domestic law, working with the ICC remains entirely lawful.
However, UK domestic legality and safety from US extraterritorial enforcement are two different things. The United States maintains broad authority to restrict access to dollar-clearing infrastructure for foreign companies and individuals who deal with designated entities. The critical question for UK entities is not whether their ICC-related activity is legal under British law — it clearly is — but whether it creates actionable exposure under the OFAC framework.
For context, the earlier targeted sanctions against individual ICC judges and prosecutors (which predated the October 2026 escalation) had already prompted some UK law firms to commission sanctions-risk assessments. The expansion of designations to the court as a whole significantly raises the stakes for any UK entity with US financial connections.

Why UK Legal Professionals Are Seeking Urgent Advice
For UK solicitors and barristers specialising in international criminal law, human rights, or sanctions compliance, the OFAC designation raises a set of immediate, practical questions that do not have easy answers:
Can a UK firm continue representing a client before the ICC? The answer likely depends on whether the representation is classified as providing professional services to a designated entity, which is prohibited, or as representing a private client in proceedings before the court, which may fall within a protected carve-out. The distinction is real, but the OFAC licence text would need to be analysed to confirm.
Does the 180-day window protect the firm while it restructures? Probably — but only if the firm takes documented steps to either wind down its ICC-adjacent work or restructure its US financial connections within the period. Passive reliance on the transition provision, without legal advice confirming its scope, is not a safe strategy.
What about funding organisations? UK-registered charities that fund ICC investigations, documentation projects, or victim-support programmes linked to ICC proceedings face particular uncertainty. US correspondent banking infrastructure is used by virtually every UK charity processing international payments. A formal legal opinion on whether each programme constitutes "services to a designated entity" may be necessary for trustees to meet their fiduciary duties.
A Concrete Scenario: A London Human Rights Chambers in October 2026
Consider a composite example that reflects real circumstances across the sector. A mid-size London human rights chambers — call it Chambers X — employs twelve barristers and three staff. It currently holds five active mandates connected to ICC proceedings: advising a victims' group in a pending case, preparing written submissions for The Hague, and running a publicly funded educational programme on international humanitarian law co-branded with an ICC outreach unit.
Two of its senior barristers trained at US law schools and retain US bank accounts. The chambers processes invoices through a US dollar account held with a UK clearing bank — entirely standard for any international practice.
Under the new OFAC designation, the exposure map looks like this:
If the licence is interpreted narrowly — covering only the ICC's internal operations, not external legal counsel — then Chambers X's five mandates could qualify as providing professional services to a designated entity. Civil penalties under OFAC can reach hundreds of thousands of dollars per violation; criminal exposure extends to $1 million per count and up to 20 years' imprisonment.
If the licence is interpreted broadly — covering transitional professional services that support ongoing proceedings — then Chambers X has until approximately April 2027 to restructure. That means either obtaining an OFAC-specific authorisation for each mandate, ring-fencing its dollar account from any ICC-related receipts, or terminating the mandates that cannot be restructured before the window closes.
The correct answer differs by mandate. The victim-advisory role may be protected under Rome Statute Article 68 provisions on victim participation; the ICC-branded educational programme may not. Determining which mandates are safe, and which require restructuring, requires a lawyer who understands both international criminal procedure and OFAC licensing — a combination that is rarer than most chambers may assume.
A barrister who acts without that advice, relying on the assumption that UK domestic legality is sufficient, could face personal designation. Two of the chambers' own barristers hold US bank accounts: under secondary sanctions logic, those accounts become a direct enforcement lever.
Three Steps Before the Window Closes
The 180-day window is not passive protection. It is a compressed timeline for action.
Map your US nexus first. Identify every dollar account, US correspondent relationship, US partner, and US-incorporated entity connected to your ICC work. If any exists, your exposure is real and the analysis needs to happen before the window expires.
Document the nature of each ICC relationship precisely. "Working with the ICC" covers a wide range of activities with different legal statuses under OFAC. Victim representation, expert testimony, academic research, and administrative consultancy each sit differently under the licensing framework. Clear documentation now supports any future licence application or compliance defence.
Consult a sanctions specialist, not a generalist. This is not standard commercial legal advice territory. An international law solicitor without specific OFAC experience will not be able to give you the opinion you need. ExpertZoom connects individuals and organisations with solicitors who combine international criminal law expertise with active sanctions-compliance practice — exactly the combination the current situation demands.
Note: This article provides general information about a rapidly evolving legal and regulatory situation. It does not constitute legal advice. Organisations and individuals who may be affected by US sanctions on the ICC should seek qualified legal advice specific to their circumstances before the 180-day transition window closes.
The UK's refusal to follow Washington is a principled stand that reflects the country's obligations under the Rome Statute. It is also, on its own, insufficient legal cover for the thousands of British lawyers, charities, and legal professionals whose work now intersects with a designated entity under US law. The time to understand that exposure — and to act on it — is now.
