A business receives notice that its accounts are frozen and its assets blocked under the UK financial-sanctions regime. The designation arrived without warning. Trade relationships collapse within days. Incoming payments are refused. The board wants to know whether the decision can be overturned – and how quickly.
Judicial review of a designation under OFSI legal support involves challenging the lawfulness of the Office of Financial Sanctions Implementation's decision to designate a person or entity before the UK High Court. The court examines whether OFSI and the Secretary of State acted within their legal powers, followed correct procedures, and made a decision that was proportionate and based on sufficient evidence. The statutory basis is the Sanctions and Anti-Money Laundering Act ("SAMLA"), and the grounds available – illegality, procedural unfairness, and irrationality – mirror the standard judicial-review framework.
This page sets out the governing law, the procedure, the cross-border dimensions that complicate most UK designations, the risk flags that determine whether judicial review is the right route, and how Calder & Vance assists businesses and individuals facing this situation.
What is the legal basis for challenging a UK designation?
SAMLA gives the Secretary of State power to designate persons under the relevant thematic sanctions regulations. That power is subject to public-law constraints. A designated person – whether an individual, a company, or another entity – may bring a judicial-review claim in the High Court (Administrative Court) seeking to quash the designation or to compel OFSI to act lawfully.
The grounds are the same as in any judicial-review claim: illegality (the decision-maker acted beyond its powers or applied the wrong legal test), procedural impropriety (the claimant was denied a fair hearing, adequate disclosure, or the opportunity to respond), and irrationality (the decision was one no reasonable decision-maker properly directing itself could have reached). Proportionality is also available where the designation interferes with rights under the Human Rights Act or European Convention on Human Rights – for example, the right to property under Protocol 1, Article 1.
The procedural route matters. A claimant must file a claim form promptly and, in any event, within three months of the date on which the grounds first arose, unless the court extends time. In our experience, this is the window that most affected parties underestimate. The three-month clock begins when the designation is made – or, arguably, when the claimant first had knowledge of sufficient grounds. Delay carries real risk of the claim being refused on procedural grounds alone before the merits are reached.
Before a judicial-review claim is issued, OFSI offers an internal-review mechanism under SAMLA. That route is faster and lower-cost than litigation, but it is conducted by OFSI itself and does not provide an independent judicial determination. Many clients pursue internal review first while simultaneously preserving the judicial-review option by monitoring the three-month clock carefully.
What grounds succeed – and which rarely do?
Not every designation is susceptible to judicial review on its merits. The court applies a standard of anxious scrutiny to decisions that affect fundamental rights, but it will not simply substitute its own assessment of the underlying intelligence for OFSI's. The analysis turns on the quality of the evidence, the adequacy of the process, and whether the test in the relevant thematic regulations was applied correctly.
Grounds that tend to carry weight include the following. Mistaken identity: the designation was made in error because the claimant's identity was confused with another person on the basis of name, nationality, or address. Where the designated person demonstrably does not match the criteria in the listing notice, the evidential foundation for the designation collapses. Procedural unfairness: the claimant was not given adequate opportunity to address the case against them before the designation was made, particularly where sensitive material was relied upon in a manner that prevented effective challenge. Legal error: the Secretary of State applied the wrong test – for example, applying a "reasonable grounds to suspect" standard when a higher threshold was required, or relying on criteria that fall outside the scope of the enabling regulation.
Grounds that face a harder path include general assertions that the decision was wrong on the facts, without specific evidence to undermine the designation package, and challenges to the weight given to intelligence material where the material itself has not been disclosed. Courts apply a degree of deference on national-security questions, though that deference is not unlimited and is subject to challenge where the procedural safeguards have not been followed.
Have you received the full statement of reasons for the designation? In many cases, that document – obtained through the pre-action protocol or by a disclosure request – is the key to identifying the real ground of challenge.
How does the OFSI process compare with OFAC, the EU General Court, and UN delisting?
Any cross-border business holding assets or conducting transactions in multiple jurisdictions is likely to face designation decisions across more than one regime simultaneously. Understanding the differences in challenge routes is essential.
Under OFAC, the equivalent challenge routes are a request for administrative reconsideration under IEEPA-based procedures, or, where rights are engaged, a legal challenge in the US federal courts. OFAC's administrative reconsideration process operates entirely within the executive branch and offers no independent judicial oversight at first instance. A federal-court action is the analogue of UK judicial review but faces significant procedural hurdles, including standing, the standard of review, and the role of classified evidence. The US process is in certain respects less transparent than the UK route, where disclosure obligations under the Civil Procedure Rules provide a more structured evidential exchange.
At the EU level, the EU General Court hears annulment actions against Council Regulations listing persons under the relevant Council decisions. The EU court has demonstrated willingness to annul designations where the Council's evidence was insufficient or where the claimant's rights of defence were not respected. Timing differs: an action for annulment before the EU General Court must be brought within two months of publication or notification of the listing measure. EU proceedings are conducted in writing and typically take significantly longer than a UK judicial-review permission stage, though interim measures can be sought to suspend the effects of the listing pending judgment.
For persons listed on the UN Security Council Consolidated List, the position is more constrained. The primary route for listed individuals and entities is through the Ombudsperson for the ISIL (Da'esh) and Al-Qaida sanctions regime, or through the Focal Point for de-listing for other UN committee lists. Those are diplomatic and administrative processes, not judicial ones. A UN listing does not, however, prevent parallel proceedings at national or EU level where a domestic or EU implementing measure is itself challengeable.
The practical implication is that a multi-jurisdictional designation requires a co-ordinated strategy. Winning a judicial-review claim in the UK does not automatically remove a listing under an OFAC programme or an EU Council Regulation. Each regime must be addressed separately. We regularly advise clients on parallel challenge proceedings across more than one regime, ensuring that the case made in each forum is consistent and does not prejudice the others.
The position above covers the standard challenge scenario. Your specific facts – the regime, the nature of the evidence relied upon, the jurisdictions in which assets are held, and the timelines already elapsed – change the analysis materially.

What is the step-by-step procedure for a judicial-review claim?
The procedure in the Administrative Court follows a defined sequence. Understanding each stage – and what drives timeline and cost – allows a claimant to make informed decisions about resource allocation before filing.
The first step is pre-action correspondence. A formal pre-action letter is sent to the defendant (ordinarily the Secretary of State, with OFSI as the administrative authority). This letter identifies the claimant, the decision challenged, the grounds, and the remedy sought. The defendant has a defined period under the pre-action protocol to respond. The pre-action stage creates the formal record and, importantly, triggers the defendant's obligation to preserve and consider disclosure of the designation package.
If the response is unsatisfactory or no response is received within the protocol period, a claim form is filed in the Administrative Court. The court then considers whether to grant permission on the papers or at an oral hearing. Permission is the gateway to the substantive hearing: the court will grant it if the claim is arguable. A strong, focused grounds document at the permission stage is critical – a diffuse or poorly evidenced claim risks refusal at this threshold, wasting the time already invested.
If permission is granted, the case proceeds to a substantive hearing. The defendant files detailed grounds of resistance and, in national-security cases, may apply to rely on closed material. A Special Advocate can be appointed to represent the claimant's interests in relation to closed material that cannot be disclosed directly to the claimant. This is a feature that distinguishes the UK system from many civil-law equivalents and provides a degree of adversarial scrutiny even in sensitive cases.
At the substantive hearing, the court will hear argument and may receive evidence by way of witness statements and exhibits. The court can quash the designation, remit the decision to OFSI for reconsideration on lawful grounds, or decline relief. It cannot itself substitute a different designation decision: that remains an executive function.
Where expedition is required – because the financial consequences of the designation are causing immediate and severe harm – an application for an expedited hearing or for interim relief can be made. Such applications are heard urgently but carry their own procedural requirements, including a demonstrable case of urgency and a willingness to give a cross-undertaking in damages if interim relief is granted.
What are the risk flags that determine whether judicial review is the right route?
Judicial review is a powerful but resource-intensive mechanism. It is not the only route to addressing a UK designation, and in some situations it is not the most appropriate first step. Identifying the right route requires a clear-eyed assessment of the grounds, the evidence, the timeline, and the likely relief.
Risk flag one: elapsed time. If more than three months have passed since the designation without a claim being filed and without grounds for extension, the procedural route may already be closed. Time is the single most unforgiving constraint in this area.
Risk flag two: absence of a specific, articulable ground. A judicial-review claim that amounts to a general denial of the factual basis for designation without pinpointing a legal error, a procedural defect, or a specific factual mistake is unlikely to survive the permission stage. The claim must identify precisely where the decision-maker went wrong in law or procedure.
Risk flag three: multi-regime designation. Where the same or related evidence supports designations in more than one jurisdiction, the risk of inconsistent positions across proceedings is real. A concession or an admission in one jurisdiction's proceedings may be picked up in another. Cross-regime co-ordination from the outset is essential, not a refinement for later.
Risk flag four: the availability of a licensing remedy. In some circumstances, a specific licence from OFSI allowing defined transactions can relieve the immediate operational harm caused by a designation while a challenge is pursued. Licensing and judicial review are not mutually exclusive strategies. We have acted for clients where a licence was the priority in the short term, with a parallel legal challenge addressing the underlying designation.
Risk flag five: incomplete evidence in the claimant's possession. Before filing, the grounds must be assessed on the best available information. That requires obtaining the designation notice and statement of reasons, reviewing what has been disclosed by OFSI, and identifying what further material is needed to assess the strength of the challenge. Filing blind – without having reviewed the full designation package – increases the risk of running the wrong ground and prejudicing the overall position.
If a designation decision has already been received, or if an OFSI review has been refused, preserving all available options requires an urgent review. Contact Calder & Vance at info@caldervance.com before the procedural clock runs further.
What are the common misconceptions about challenging an OFSI designation?
Several misunderstandings circulate among clients and, occasionally, among advisers unfamiliar with this area. Addressing them directly helps set realistic expectations before any instructions are given.
The most common myth is that judicial review will succeed simply because the designated person is innocent of wrongdoing. Judicial review is a review of the lawfulness of the decision, not a rehearing of the facts on the merits. The court is not conducting a trial of the underlying conduct. A claimant who is factually innocent but whose designation was procedurally correct and based on evidence that met the legal threshold in the enabling regulation will not necessarily succeed. The legal test for unlawfulness is not the same as the factual test for guilt or innocence. That said, where the evidential basis is genuinely thin or where the identity is mistaken, those facts will support specific legal grounds – illegality or irrationality – that do translate into reviewable error.
A second misconception is that OFSI will simply withdraw a designation if the claimant writes a letter of explanation. OFSI's internal-review mechanism under SAMLA is a formal process. It requires structured submissions, a clear evidential package, and engagement with the specific criteria that informed the original designation. An informal letter of protest rarely achieves withdrawal. In our experience, the quality of the evidence package submitted at the internal-review stage is often determinative of whether that route produces a result – and it also shapes what is available for judicial-review purposes if the internal route fails.
A third misconception is that the only relevant jurisdiction is the United Kingdom. Designated persons frequently hold assets, maintain bank accounts, or conduct trade in multiple jurisdictions. The designation notice from OFSI imposes UK-law obligations. But a parallel designation under an OFAC programme, an EU Council Regulation, or the UN Consolidated List carries independent legal force in its own jurisdiction. Each must be addressed separately. UK judicial review does not bind OFAC or the EU Council, and a UK court cannot quash a UN Security Council listing.
How does Calder & Vance approach a judicial-review instruction?
We approach each judicial-review instruction as a structured exercise in evidence, procedure, and strategy. Our work in this area covers the full lifecycle of a designation challenge.
At the outset, we assess the grounds: we review the designation notice and any statement of reasons, identify the specific legal error or procedural defect, and advise on the realistic prospects of success at the permission stage. That assessment shapes the decision whether to proceed to judicial review, to pursue the internal SAMLA review first, or to combine both approaches.
Where a claim is to be filed, we build the evidence package: we gather documentary and witness evidence to support the identified grounds, instruct any necessary expert evidence on factual questions, and prepare the grounds document to maximise the strength of the permission application. We co-ordinate with OFSI's legal team on the pre-action protocol and manage the pre-action correspondence.
For multi-regime matters, we co-ordinate the challenge strategy across jurisdictions. Where a client faces parallel designations under OFAC or EU programmes, we work with local counsel in the relevant jurisdiction to ensure that the positions taken in each forum are consistent and strategically aligned. We have acted on matters where the UK judicial-review proceedings and an EU General Court annulment action were running concurrently, requiring careful management of timing and disclosure.
In a recent matter, a financial-services business designated under a UK sanctions programme faced immediate asset-freeze consequences affecting its operating accounts. We assessed the grounds within 48 hours of instruction, identified a procedural-unfairness argument based on the claimant not having been given adequate prior notice under the applicable procedure, secured an expedited hearing slot, and managed the pre-action protocol correspondence within the timeline the client required. The matter proceeded to internal review. No guarantee of outcome is offered; the point is the approach and the speed.
Our work does not end at the designation. Where a client succeeds in having a designation quashed or withdrawn, we advise on the downstream requirements: notification to banks and counterparties, unwinding of frozen-asset restrictions, and addressing any consequences for pending transactions. We also advise on OFSI licensing as a parallel short-term measure to restore operational capacity while proceedings are ongoing.
