A trading company with operations across three continents receives notice that one of its affiliated entities has been placed on a sanctions list. Within days, correspondent banks suspend payment lines, counterparties invoke material adverse change clauses, and the compliance team is fielding calls from regulators in two jurisdictions simultaneously. The designation did not come from a single authority. It came from three. The question is not simply whether the listing was lawful. The question is which court, under which rules, hears the challenge – and in what order.
Judicial review of a designation across regimes requires a separate legal challenge in each jurisdiction whose list carries the name. Under the EU regime, an annulment action (a challenge to the legality of a Council designation before the EU General Court) must be brought within a defined limitation period. Under UK law, a statutory review process before OFSI and, where necessary, a judicial review claim before the High Court apply. Under OFAC, an administrative petition and, ultimately, a federal court action govern the position. The procedures are parallel, not sequential, and missing a deadline in one jurisdiction does not pause the clock in another.
This guide sets out the step-by-step procedure for judicial review of a designation in each of the three principal regimes, identifies where they diverge, and explains the risk flags that most commonly derail a cross-border challenge. The guide follows a decision-tree structure: each branch corresponds to the reader's specific jurisdictional position.
What triggers a cross-border designation challenge?
A cross-border designation challenge arises when the same person or entity is listed by two or more authorities – typically OFAC, the EU Council, and OFSI – whether concurrently or in sequence. The trigger is the practical consequence: asset freezes, transaction prohibitions, and reputational damage that operate in every jurisdiction where the designated party or its assets have a presence.
Designation decisions are made by different legal mechanisms in each regime. OFAC acts under authority derived from IEEPA or other primary legislation, issuing designations by executive order. The EU Council acts by a Council Decision and a directly applicable Council Regulation. OFSI administers designations made under the relevant thematic sanctions regulations enacted pursuant to the Sanctions and Anti-Money Laundering Act ("SAMLA"). The UN Security Council Consolidated List operates through Chapter VII resolutions and is implemented domestically by each of those regimes. Each legal instrument creates a separate legal right to challenge – and a separate procedural pathway.
In our experience, the moment a designation lands in more than one jurisdiction, the timeline for challenge compresses sharply. A designated party that focuses only on the most familiar regime risks letting a limitation period expire elsewhere before it has even engaged local counsel.
If you are listed by the EU Council: the annulment action route
If your entity is designated under an EU Council Regulation, the primary judicial remedy is an annulment action before the EU General Court, brought under the legal authority that governs direct actions against Council acts. The action challenges the legality of the listing decision itself – the sufficiency of the evidence, procedural compliance, proportionality, and the right to an effective remedy.
The EU General Court examines the Council's listing decision on the merits of the evidence presented. In practice, the Council must provide the designated party with a statement of reasons at or shortly after designation. That statement of reasons is the foundation of the annulment action: it defines the factual case the designated party must answer and, crucially, identifies any gaps or deficiencies that the action can exploit.
The procedural sequence typically runs as follows. First, the designated party must be notified and must receive the statement of reasons. Second, the party files an application for annulment with the EU General Court within the applicable limitation period. Third, the Council files a defence. Fourth, the parties exchange written pleadings. Fifth, in some matters, a hearing is held. Sixth, judgment is issued. An unfavourable judgment at the General Court can be appealed to the Court of Justice of the European Union on points of law only.
Pending the outcome of an annulment action, the designated party may apply for interim measures – a provisional suspension of the listing – but such relief is granted only in exceptional circumstances, and the threshold is demanding. Clients should not assume that filing the action itself provides breathing room for transactions.
The position above covers the standard case. Your facts – the identity of the counterparty, the nature of the listed assets, the jurisdictions where those assets are held, and the regime in play – change the analysis materially.

If you are listed by OFSI: the UK review and challenge route
If your entity is designated under a UK thematic sanctions regulation made under SAMLA, the first step is to request a review by OFSI. OFSI is required to consider the designation and provide reasons. The administrative review does not suspend the designation. It is, however, a precondition that must ordinarily be exhausted before a judicial review claim in the High Court becomes the appropriate next step.
Judicial review before the UK High Court challenges the lawfulness of the designation decision. The grounds available include illegality, procedural impropriety, and, in appropriate cases, breach of fundamental rights. The High Court applies the relevant public law standards; it does not re-take the original designation decision on the merits in the same way the EU General Court does.
A separate route exists for individuals seeking to challenge their listing through representations under the OFSI process. For companies operating across the UK and EU, a critical tactical question arises: the grounds for challenge and the available evidence may not map cleanly between the two proceedings. An argument that succeeds before the EU General Court – for instance, that the Council's evidence was procedurally defective – may not translate into a successful UK judicial review claim, because the legal tests and the institutional standards differ.
For matters with both UK and EU exposure, we regularly advise on the sequencing of the two challenges. Running them in parallel is usually necessary where the limitation periods are close. Allowing one to run first risks the second tribunal drawing adverse inferences from an unfavourable outcome – a risk that can be managed but must be anticipated.
If a filing has already been made in one jurisdiction, or a review request has been refused, an early assessment of the remaining options can preserve routes that narrow with time. Contact us at info@caldervance.com.
If you are listed by OFAC: the US administrative and judicial route
If your entity is designated by OFAC, the primary route is an administrative petition for reconsideration. OFAC will review the petition and either maintain the designation, modify it, or revoke it. The administrative process does not involve a formal hearing before an independent tribunal. OFAC acts as the reviewing authority as well as the original designating authority.
Where the administrative petition fails, a federal court action challenging the designation is available. Federal courts apply standards of judicial review that are generally deferential to agency action under US administrative law. The standard of review is a material constraint: the court typically asks whether the agency's decision was arbitrary, capricious, or otherwise unlawful, rather than conducting a full merits review of the underlying evidence.
A cross-border business with EU or UK listings will immediately notice the contrast. The EU General Court's annulment jurisdiction is broader and more willing to examine the evidential sufficiency of a listing. The US federal court review is more constrained. This structural difference shapes litigation strategy: the EU action may offer a cleaner evidentiary challenge, while the US process may benefit more from the robustness of the administrative petition record and any voluntary self-disclosure (VSD) considerations in an associated OFAC enforcement context.
Secondary-sanctions risk adds a further dimension. Even a party that successfully challenges its OFAC listing before a federal court remains subject to EU and UK designations, which operate independently. Conversely, an EU delisting does not remove OFAC jurisdiction. A business operating across these regimes must treat each challenge as legally distinct, even where the factual basis for all three listings is the same.
How does the UN Consolidated List interact with a cross-border challenge?
A designation on the UN Security Council Consolidated List operates through Chapter VII resolutions and is implemented by domestic regimes, including those of the EU, the UK, and individual member states. Where a listing originates from a UN Security Council Committee, the domestic challenge may not be sufficient: even a successful annulment action before the EU General Court will not, of itself, remove the underlying UN listing.
The UN provides two de-listing mechanisms. For the ISIL and Al-Qaida sanctions regime, an independent Ombudsperson considers petitions from designated individuals and entities and makes recommendations to the Security Council Committee. For other UN sanctions committees, a Focal Point mechanism exists. Neither mechanism involves a court in the conventional sense. They are administrative in character, and outcomes are not guaranteed. The Ombudsperson's recommendations are not binding on the Committee.
For a cross-border business facing both a UN listing and domestic listings in the EU, UK, and US, the sequencing of challenges must be planned carefully. A domestic annulment action may succeed in suspending the domestic effects of a listing even where the UN listing remains. But the practical value of that outcome depends on where the party's assets and operations are located. In our practice, the UN dimension is often underweighted at the outset, creating procedural complications that are difficult to correct once the domestic proceedings are under way.
What are the common pitfalls in a cross-border designation challenge?
The most common pitfall is misidentifying the limitation period. Each regime operates its own deadline for challenge, and none of them automatically extends because proceedings are on foot elsewhere. A party that receives a designation notice late – whether because of postal delivery, intermediary notification, or a complex corporate structure – must obtain specialist advice immediately on the applicable deadline in every relevant jurisdiction.
A second recurring error is treating the statement of reasons as a static document. In EU proceedings, the Council may supplement its reasons during the course of the litigation. Late disclosure of additional evidence can shift the litigation landscape significantly. Parties who have not built their pleadings to accommodate this possibility can find themselves responding to a stronger evidential case than the one they originally challenged.
A third pitfall is the co-ordination failure between legal teams in different jurisdictions. Where separate counsel handle the EU, UK, and US proceedings without an overarching co-ordinating adviser, inconsistencies can emerge in the factual narrative presented to each tribunal. A statement made in EU proceedings – particularly in written pleadings filed in a public record – may be used in US proceedings. Discipline across the record requires a single point of strategic oversight.
A fourth risk is underestimating the reputational and operational timeline. Even where a challenge is well-founded, the proceedings take time. Business relationships, financing arrangements, and correspondent banking access may not survive the duration of litigation. A well-structured challenge must be accompanied by a parallel engagement with affected counterparties, regulators, and financial institutions. Waiting for the court's judgment before managing those relationships is a strategic error.
A fifth, and often overlooked, pitfall is the assumption that a de-listing in one regime automatically relieves the position in another. We have acted for clients who obtained a successful annulment before the EU General Court, only to find that their OFAC and OFSI designations continued to restrict their operations and that counterparties required evidence of all three removals before resuming normal dealings.

Step-by-step: building a cross-border challenge
The following decision sequence reflects the approach we take when a client presents with a designation across multiple regimes. It is a practitioner's operational guide, not a guarantee of outcome.
- Triage the listing notices. Identify every regime in which the entity or individual is listed and the date of each notification. Record the applicable limitation periods for challenge in each jurisdiction immediately. Do not assume that the dates run from the same trigger event.
- Obtain and analyse the statements of reasons. Request the statement of reasons from each designating authority if it has not been provided. The EU Council is required to provide reasons; OFAC and OFSI provide reasons in different ways and with different levels of detail. Map the factual allegations across all three and identify where they overlap and where they differ.
- Assess the UN dimension. Determine whether any of the domestic designations implements a UN Security Council Committee listing. If so, identify the applicable de-listing mechanism – the Ombudsperson or the Focal Point – and assess whether a petition is available and realistic.
- Instruct co-ordinating counsel and local counsel. For a cross-border challenge, a single legal adviser should hold the strategic oversight. Local counsel in the relevant jurisdiction handles domestic procedural requirements. The division of responsibility must be clear from the outset.
- Prepare the evidence package. For the EU annulment action, this means a detailed factual rebuttal of the statement of reasons, supported by documentary evidence. For OFAC, it means building the administrative petition record. For OFSI, it means assembling the representations. The underlying facts are the same; the framing and emphasis differ by regime.
- File in strict deadline order. Where limitation periods are close in time, prioritise the earliest. Notify the other relevant authorities of the proceedings as required. Consider whether interim measures applications are warranted in any jurisdiction and the realistic prospects of obtaining them.
- Manage the commercial position in parallel. Engage affected correspondent banks and counterparties. Where possible, provide documentation of the challenge to explain the legal position. Explore whether any general or specific licences are available in any regime to permit essential transactions during the currency of the proceedings.
- Monitor the proceedings across all jurisdictions. Track developments in each set of proceedings. An adverse interlocutory decision in one jurisdiction may need to be managed in the context of the others. Maintain a consistent factual record.
In a recent matter, a financial services group discovered that three affiliated entities had been designated under both EU and UK thematic regulations following the same set of transactions. We co-ordinated the EU annulment action and the OFSI review process concurrently, ensuring that the factual record filed in each proceeding was consistent and that the limitation period for the EU filing was met while the OFSI administrative review was still pending. The matter required careful staging of the documentary evidence and close liaison with the client's operational teams to manage correspondent banking relationships during the proceedings.
