A trading company wakes to find its name on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). Within hours, correspondent banks have frozen accounts, counterparties have suspended contracts, and the company's legal counsel is fielding calls it cannot answer quickly enough. The designation is live. The damage is immediate. The question that matters now is whether the designation can be challenged – and how.
Judicial review of a designation under OFAC legal support is available through the US federal courts, where a designated party may challenge both the procedural fairness and the substantive basis of the designation. The standard of review is deferential to the executive, but courts have vacated designations where due-process requirements were not met or where the evidentiary basis was found legally insufficient. As of March 2026, the administrative reconsideration route before OFAC and the judicial route in the federal courts are not mutually exclusive – running both in parallel, carefully sequenced, is often the stronger position.
This page explains the governing regime, the judicial and administrative routes available to a designated party, how the US position compares with OFSI and the EU, the practical risk flags that counsel watches, and how Calder & Vance can assist from the moment a designation lands.
What authority governs OFAC designations and the right to challenge them?
OFAC derives its designation authority primarily from IEEPA (the International Emergency Economic Powers Act) and, in certain programmes, from TWEA (the Trading with the Enemy Act), both of which confer broad powers on the executive to block property and prohibit transactions. The SDN List is OFAC's primary instrument for implementing those powers against named parties.
A designated person or entity receives, at the point of designation, a notice identifying the regulatory basis and the general grounds. That notice does not typically include classified intelligence material. This is the first structural tension in any challenge: the designated party must mount its case without full sight of what OFAC relied upon. Courts have grappled with this tension under constitutional due-process doctrine, and the outcomes are fact-specific.
The two formal challenge routes are, first, an administrative reconsideration petition submitted directly to OFAC – requesting delisting on the ground that the designation is factually wrong, that circumstances have changed, or that a licence offers an adequate remedy – and, second, a judicial review action filed in a US federal district court, alleging that OFAC acted unlawfully, exceeded its statutory authority, or violated constitutional rights. In our experience, the choice between routes, and the sequencing of them, is the first and most consequential decision a designated party must make.
How does judicial review of an OFAC designation proceed in the federal courts?
A federal court reviewing an OFAC designation applies the standard set out in the Administrative Procedure Act: the designation stands unless it is arbitrary, capricious, an abuse of discretion, contrary to constitutional right, or in excess of statutory jurisdiction. That is a demanding standard for a challenger to overcome, but it is not insurmountable.
The procedural sequence typically runs as follows. After filing, the government produces an administrative record – the materials OFAC considered in reaching the designation. Where classified material is in the record, the court may review it in camera without disclosing it to the petitioner. The petitioner then argues that the unclassified record, taken alone or together with the classified material, does not legally support the designation. Cross-motions on the administrative record are common; live evidence and witness testimony are the exception rather than the rule.
What does this mean in practice? Courts have required OFAC to demonstrate that its factual conclusions bear a rational connection to the evidence in the record. Where the agency's reasoning is circular, relies on a single tainted link in an ownership chain, or applies an incorrect legal test, the court has grounds to remand or vacate. In our cross-border practice, we regularly advise clients on which parts of the administrative record are the weakest points of the government's case – and how to construct the argument that exploits those weaknesses.
Timing is a constant pressure. There is no statutory deadline forcing OFAC to produce the administrative record promptly, and litigation can extend over a year or more. Meanwhile the designation remains in force and the financial consequences compound. Counsel must therefore plan for interim measures – emergency licence applications, asset-management authorisations, and communications with financial counterparties – running in parallel with the litigation.
How does the OFAC judicial-review route compare with OFSI and the EU General Court?
The US, UK, and EU routes share the same pressure point – they all challenge an executive act supported by at least some confidential material – but the procedure and the standard of review differ in ways that matter for a cross-listed party.
Under OFSI (the UK's Office of Financial Sanctions Implementation), a designated party may request an internal review and, thereafter, apply for judicial review in the High Court under the standard applicable to judicial review of administrative decisions. The UK court applies a proportionality analysis where the designation engages rights under the Human Rights Act, which is in some respects more searching than the US arbitrary-and-capricious test. Where a designation was made under UK authority independently of OFAC, a successful challenge in London does not automatically lift the US designation.
Before the EU General Court, a designated party brings an annulment action under the EU treaties. The General Court has a well-developed body of case law on the sufficiency of reasons that must accompany a Council designation. The Court has annulled designations where the Council failed to state adequate reasons, where the evidence relied on was insufficient, or where the right to be heard was not respected. The General Court's approach to proportionality review is, in practice, more willing to examine the substantive basis of a designation than US federal courts have historically been – though the margin of appreciation afforded to the Council remains wide.
For a party designated by both OFAC and the EU Council, the strategic question is whether to run parallel proceedings, and how to sequence them. A win before the EU General Court does not bind OFAC, and vice versa. But a successful EU annulment can materially strengthen the factual record available to US counsel, and the reverse is also true. We regularly advise on this cross-regime sequencing, and it is one of the clearest illustrations of why cross-border sanctions counsel adds value that a single-jurisdiction firm cannot replicate.
The position in Singapore, Japan, and UAE is different again. Those regimes do not offer an equivalent judicial-review mechanism, but they do have administrative reconsideration routes, and a designation under one of those regimes that is concurrent with OFAC creates a distinct compliance burden that requires coordinated advice.
The bridge between these regimes is the UN Consolidated List. A listing by the Security Council – particularly under the ISIL/Al-Qaida regime – does not itself give rise to a US court challenge, but it frequently sits behind both the OFAC and the EU designations. The Ombudsperson mechanism before the relevant Security Council committee offers a separate delistment route that runs independently of US and EU court proceedings.
What are the risk flags that counsel watches before filing?
Not every designation is worth litigating to judgment. Some are better resolved by administrative reconsideration; others by a specific-licence application that restores essential operations while the factual record is developed. Before filing, counsel must assess several critical risk flags.
The first is the quality of the evidentiary record available to the designated party. If the client can demonstrate with documentary evidence – corporate records, financial statements, ownership agreements, third-party evidence – that the factual basis of the designation is wrong, that strengthens the case for both the administrative and judicial routes. If the key evidence is in the hands of a third party or a foreign authority, its accessibility must be planned early.
The second risk flag is secondary-sanctions exposure. A non-US entity challenging an OFAC designation must be aware that its legal activities during the litigation – engaging US counsel, communicating with OFAC, accessing US courts – may themselves require a specific licence or fall within a general authorisation. Confirming the licence position before the first filing is not a formality; it is a necessity.
The third risk flag is the interaction with concurrent proceedings. If the party is also under investigation by DOJ, or if there is a parallel civil forfeiture action, the litigation strategy must account for the risk that statements made in the OFAC challenge are later used in the criminal or civil proceeding. Attorney-client privilege and the Fifth Amendment implications require careful structural planning at the outset.
A fourth risk flag, which in our experience is often underweighted by clients, is the reputational and commercial effect of filing a public court case. Federal court filings are public. The existence of the litigation – and every substantive motion – is visible to counterparties, banks, and press. Where a party's priority is to restore banking relationships as quickly as possible, a targeted administrative reconsideration supported by a compliance remediation plan may achieve that faster than multi-year litigation, even if the litigation is eventually stronger on the merits.
What is the role of administrative reconsideration alongside judicial review?
Administrative reconsideration before OFAC and judicial review in the federal courts are parallel tracks, and the decision to use both – or to sequence one before the other – is a matter of strategy, not formality.
An administrative reconsideration petition to OFAC sets out why the designation is wrong and requests that OFAC remove the name from the SDN List. OFAC's review is internal and does not follow an adversarial or hearing-based procedure. OFAC may deList, deny, or decline to respond within any statutory time window. There is no binding deadline on OFAC to decide, which is a significant operational risk for a business with frozen assets.
Filing for administrative reconsideration does not toll any limitations period for a federal court action. Courts have addressed this question, but the position depends on the specific programme and the relevant statutory scheme. Counsel must identify the applicable limitations period early and not allow the administrative track to run the clock down.
Where OFAC denies a reconsideration petition, or fails to act within a reasonable period, the denial or non-response can itself become the basis of a judicial-review claim – arguing that OFAC's failure to act is itself arbitrary and capricious. This is a useful but legally uncertain ground that requires specific facts to support it.
In a recent matter, a financial-services business found itself on the SDN List following its acquisition of a company that had an undisclosed connection to a listed person. We assessed the ownership chain, identified the factual error in OFAC's attribution, and filed both an administrative reconsideration petition supported by a detailed compliance remediation programme and a parallel federal court action. The administrative track produced an interim specific licence restoring partial operations while the merits were developed. The matter illustrated that the two tracks, run together, can produce interim commercial relief faster than either alone.
Common myths about challenging an OFAC designation
The most persistent myth we encounter is that a judicial challenge to an OFAC designation is futile because courts always defer to the executive on national-security matters. That is not accurate.
Courts do apply a deferential standard, and they do permit the government to rely on classified material the petitioner cannot see. But courts have vacated designations where the unclassified record alone was legally insufficient. They have remanded cases where OFAC's stated reasoning was internally inconsistent. They have held that due-process protections apply to designated parties, even foreign ones, in certain circumstances. The deference is real, but it is not unlimited – and the cases where it has been overcome are not anomalies.
A second myth is that a delisting petition to OFAC is always faster and therefore always preferable to a court challenge. Administrative reconsideration has no statutory deadline, no hearing, and no adversarial procedure. It can be faster when the facts are clear and the error is obvious. But where OFAC is not going to concede the error without legal compulsion, the administrative track can extend for years while the designation remains in force. The judicial route, despite its own delays, imposes a litigation schedule on both parties and creates public accountability for OFAC's position.
How Calder & Vance assists with judicial review of an OFAC designation
Judicial review of a designation under OFAC legal support from Calder & Vance is structured around the specific pressures of a live designation: frozen assets, suspended banking, and the immediate need for operational relief alongside the long-term project of challenging the designation's legal basis.
Our work covers the following actions, matched to where a client is in the process:
- Assessment: we review the designation notice, the SDN List entry, and the client's ownership and transaction records to identify the factual and legal weaknesses in OFAC's position.
- Licensing: we assess eligibility for a specific licence to restore essential operations, prepare and submit the application, and manage OFAC's queries during review.
- Administrative reconsideration: we build the evidence package, prepare the petition, and manage the process through to OFAC's decision or a decision to escalate to court.
- Judicial strategy: we advise on the choice of court, the timing of filing, the grounds for challenge, and the interaction with any parallel proceedings (criminal, civil forfeiture, or proceedings in other regimes).
- Cross-regime coordination: where the designation is concurrent with OFSI, the EU Council, or another regime, we advise on the sequencing of proceedings and coordinate with local counsel in the relevant jurisdiction.
- Compliance remediation: where the designation followed a genuine compliance failure, we design the remediation programme that supports both the administrative petition and the litigation narrative.
We operate on fixed-fee entry points for the assessment and strategy phase, so clients know their cost exposure before committing to the process. Subsequent stages are quoted on scope.
