A multinational's compliance team flags a counterparty on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). But the designated entity is your client. The designation landed without prior notice. Assets are frozen, correspondent banks have severed their lines, and incoming payments are blocked. The administrative reconsideration process has run its course without relief. What remains? As of March 2026, the answer for US-connected designees is a direct challenge in the federal courts – and the rules governing that route are specific, demanding, and often misunderstood.
Judicial review of a designation under OFAC is a constitutional and administrative-law challenge brought before the US federal courts, typically the US District Court for the District of Columbia, seeking to set aside a designation as arbitrary, capricious, or contrary to law under the Administrative Procedure Act ("APA"). The governing authority is OFAC within the Department of the Treasury, acting under statutory powers including IEEPA, TWEA, and programme-specific legislation. Courts review the administrative record compiled by OFAC; the standard is highly deferential to the executive, but it is not unlimited.
This briefing sets out how the judicial review route works, how it compares with the EU General Court and OFSI routes, the risk flags that practitioners watch for, and when to instruct counsel.
Who administers OFAC designations, and what is the legal basis for challenging them?
OFAC administers US economic sanctions under authority delegated by the President through executive orders issued primarily under IEEPA and, for older programmes, the Trading with the Enemy Act ("TWEA"). The designation of a person or entity to the SDN List, or to another restricted list, is an executive act. It triggers immediate asset-blocking and a near-total prohibition on US-person dealings.
The legal basis for challenging a designation in court is principally the APA, which permits a person adversely affected by a final agency action to seek judicial review. The constitutional overlay is significant: due-process arguments under the Fifth Amendment are routinely raised alongside APA claims, particularly where the designated party received minimal pre-designation notice or where the evidentiary basis disclosed in the administrative record is thin.
OFAC is also obliged, under the relevant statutory framework, to maintain a process by which designated persons may seek administrative reconsideration. That process – the petition for reconsideration or delisting petition – is not a condition precedent to federal-court litigation in all circumstances, but in our experience the administrative record compiled during that process becomes a central document in any subsequent judicial challenge. Exhausting the administrative route first, or at least pursuing it in parallel, is generally sound tactics rather than a procedural luxury.
The position above covers the standard case. Your facts – the programme under which the designation was made, the nationality of the designated person, and the evidence OFAC disclosed – change the analysis materially.

What standard do federal courts apply when reviewing an OFAC designation?
Federal courts reviewing an OFAC designation apply the APA's arbitrary-and-capricious standard, which requires the court to ask whether the agency's decision was the product of reasoned analysis, supported by the record, and within the scope of the statutory authority conferred. The standard is deferential. Courts are not fact-finders in the ordinary sense; they review the record OFAC compiled, not the de novo merits of the designation.
The deference accorded to OFAC is reinforced by the foreign-affairs and national-security context. Courts have acknowledged, repeatedly, that the executive branch commands special institutional competence in assessing threats to national security and foreign policy. That acknowledgment translates into a reluctance to second-guess factual judgements embedded in classified or sensitive intelligence material.
Nevertheless, the deference is bounded. Courts have found that where the administrative record is composed almost entirely of allegations rather than evidence, where OFAC has relied on an informant's hearsay without corroboration, or where the agency applied the wrong legal test to the facts of a programme, the arbitrary-and-capricious standard can be met. The procedural-due-process route has also produced results: courts have found deficiencies where a designee was given no meaningful opportunity to respond to specific factual claims before the designation was finalised.
Practitioners note a practical asymmetry. The government can, and frequently does, supplement the public administrative record with classified materials presented to the court through an in camera, ex parte procedure. The designee and their counsel may not see that material, which limits the ability to rebut it directly. Cleared counsel arrangements, where available, can partially address this – but that mechanism has its own constraints.
What does the OFAC designation process prohibit, and what relief can a court grant?
An OFAC designation to the SDN List immediately prohibits all US persons from engaging in transactions or dealings with the designated party and requires the blocking of all property and interests in property within US jurisdiction. Correspondent banking access is effectively severed. The designation is applied globally to property within US jurisdiction, giving it a substantial extraterritorial reach wherever dollar-clearing or US-person intermediaries are involved.
A court that finds a designation unlawful can order OFAC to remove the designation, vacate the agency action, or remand the matter to the agency for further proceedings consistent with the court's ruling. Remand without vacatur is an outcome to plan for: the court sends the matter back to OFAC with instructions, and the agency may re-designate on a corrected basis. That possibility shapes litigation strategy from the outset.
Courts have declined to grant preliminary injunctive relief in most challenges, given the high burden – likelihood of success on the merits, irreparable harm, balance of equities, public interest – and the executive's argument that sanctions enforcement is itself a public interest. However, the preliminary-injunction route is not foreclosed and should be assessed in cases of acute operational harm where speed matters.
If a transaction has already been blocked, or a designation has already disrupted a business relationship, an early legal review can preserve options that narrow with time.

How does the US judicial review route compare with the EU General Court and OFSI routes?
The three principal Western sanctions systems each provide a distinct judicial or quasi-judicial route for contesting a designation, and the differences are material for any cross-border designee.
In the EU, a designated person may bring an action for annulment before the EU General Court under the Treaty on the Functioning of the European Union. The General Court applies its own standard of review and does not extend the same degree of deference to the Council as US courts extend to OFAC. Crucially, the General Court has found designations unlawful on the basis of insufficient evidence or procedural irregularity more frequently than US courts have vacated OFAC actions in contested cases. The Court reviews the reasoning of the Council measure, and a failure to state adequate reasons is itself an independent ground for annulment.
In the United Kingdom, OFSI administers financial sanctions under the Sanctions and Anti-Money Laundering Act ("SAMLA"). A designated person may request a review by the Minister and, thereafter, may bring a judicial-review challenge before the High Court. The UK High Court applies a public-law standard that shares features with both the US APA approach and EU proportionality analysis, but it is calibrated to the UK constitutional settlement. The UK route also includes a right of appeal on the merits in certain circumstances, which the US APA route does not straightforwardly provide.
A significant practical difference concerns the disclosure of evidence. EU and UK proceedings have developed mechanisms – sometimes involving special advocates or confidentiality rings – that allow a designated person's legal team to engage with sensitive material more directly than the US in camera, ex parte procedure typically permits. That difference can determine how effectively a challenge can be mounted.
For a designee with connections to multiple jurisdictions, the choice of forum – or the sequencing of parallel challenges – is itself a strategic decision. We regularly advise clients operating under simultaneous OFAC, OFSI, and EU designations on how to coordinate those proceedings to maximum effect.
What are the key risk flags and procedural pitfalls in an OFAC designation challenge?
Five risk flags recur in our practice when assessing an OFAC designation challenge.
Thin or undisclosed evidence in the record. OFAC is not required to disclose classified intelligence to the designee before the designation is made. The public version of the administrative record may be sparse. If the disclosed basis is limited to a recitation of the statutory standard, the challenge has more traction than if OFAC has produced detailed unclassified evidence. Assess the record early.
Secondary-sanctions exposure for counsel and service providers. Providing legal services to a designated person is subject to its own authorisation requirements under the applicable OFAC programme. Counsel operating in the US must confirm that a general or specific licence covers the representation. Our cross-border practice routinely addresses this at the outset of any engagement involving SDN-listed clients.
The 50 percent rule and entity chains. The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) means that a challenge to the root designation, if successful, can resolve derivative blocking of related entities – but only if the ownership and control chain is carefully mapped. A partial success that lifts one designation while others remain has limited commercial effect.
Parallel criminal exposure. OFAC civil enforcement and DOJ criminal prosecution under the export control and sanctions statutes can run concurrently. A strategy in the civil administrative or judicial channel must be coordinated with any criminal-exposure assessment. Admissions made in one proceeding can affect the other.
Delay. The federal dockets in the District of Columbia are congested. Litigation timelines are measured in years, not months. Interim relief – an injunction preserving business operations pending a final decision – is difficult to obtain. Businesses that cannot sustain protracted litigation without operational cash flow face a practical constraint the legal merits alone cannot resolve.
How is a judicial review challenge to an OFAC designation enforced and what are the practical steps?
Enforcement of a successful judicial-review judgment runs against OFAC: the court's order requires the agency to remove the designation and delist the party from the SDN List or relevant restricted list. OFAC then publishes the removal, which signals to banks, counterparties, and screening systems that the prohibition has been lifted. In practice, clearing the downstream consequences – de-blocking correspondent accounts, reversing contract terminations, reinstating trading relationships – takes additional time after formal delisting.
The practical sequence for pursuing a judicial challenge typically runs as follows. First, instruct counsel with both the relevant OFAC programme expertise and federal litigation experience, and confirm the authorisation position for that representation. Second, obtain and analyse the full public administrative record and any prior correspondence with OFAC, including responses to the delisting petition. Third, assess the evidentiary and legal grounds: APA arbitrary-and-capricious; due-process; statutory ultra vires; and whether classified material is likely to feature and in what form. Fourth, determine whether a parallel administrative petition is still live, or whether the agency has issued a final denial that crystallises the right to sue. Fifth, file in the US District Court for the District of Columbia, which has developed the most substantial body of case law on these questions. Sixth, manage the record-supplementation issue and the classified-material procedure as it arises in the litigation.
A voluntary self-disclosure ("VSD") to OFAC of potential apparent violations is a distinct process and should not be conflated with a designation challenge. The two may run concurrently where a business is both designated and under investigation for apparent violations, but they are governed by different procedures and serve different purposes.
In a recent matter, a financial-services group faced a designation that had been made under a thematic sanctions programme on the basis of the group's alleged relationship with a restricted entity. We analysed the public administrative record, identified a material factual error in OFAC's characterisation of the ownership chain, and prepared the administrative record supplementation and the petition for reconsideration. The matter reached the review stage with a substantially fuller evidentiary record. No specific outcome is guaranteed, and every matter turns on its own facts.
When does a designation also trigger export-control consequences, and what is the cross-border dimension?
An OFAC designation does not automatically create an export-control prohibition, but the two regimes frequently interact. BIS maintains the Entity List under the Export Administration Regulations ("the EAR"), and a person simultaneously listed on the SDN List and the Entity List faces compounded controls: not only are financial dealings prohibited by OFAC, but the supply of items subject to the EAR requires a BIS licence that may be subject to a policy of denial.
For a non-US entity designated by OFAC, the extraterritorial reach of US sanctions operates through the dollar-clearing system and through the involvement of US persons in the transaction chain. A European or Asian counterparty that continues business with an SDN-listed entity after designation exposes itself to secondary-sanctions risk – the risk that OFAC will designate it in turn for providing material support to the listed party. That risk is calibrated to the degree of the relationship: a routine trade supplier faces a different exposure level than a strategic financial partner.
The interaction with EU and UK designations is also operationally significant. OFAC, OFSI, and the EU Council do not always designate the same parties at the same time. A party delisted by the EU General Court on procedural grounds may remain on the SDN List. A party that has never attracted an EU listing may face OFAC secondary-sanctions exposure by virtue of its dealings with a third-country SDN. Compliance counsel advising on a designation challenge must map all active designations across the relevant regimes, not only the primary OFAC listing.

Common misconceptions about judicial review of an OFAC designation
A persistent misconception is that winning an APA challenge to an OFAC designation simply requires demonstrating that the underlying facts were wrong. That is not the legal standard. The court does not retry the factual record de novo. It asks whether OFAC's factual findings were supported by substantial evidence and whether the agency's reasoning was rational on the record before it. A designee may be able to show that certain factual claims were inaccurate, but unless that inaccuracy undermines the sufficiency of the record as a whole, a court will not vacate the designation on that basis alone.
A second misconception is that the delisting petition to OFAC is merely a formality to be filed before "the real fight" in court. The administrative process is, in our practice, substantively important. The record built during a petition for reconsideration – the evidence submitted, the arguments made, OFAC's responses – becomes the administrative record that the federal court will review. A poorly constructed petition limits the evidentiary foundation of any subsequent litigation. The two processes are linked, not sequential alternatives.
Third, some businesses assume that a successful EU General Court annulment, lifting an EU designation, will automatically persuade OFAC to delist. The two institutions are legally independent. An EU judgment has no binding effect on OFAC. It may have some persuasive or political weight in the OFAC administrative-review process, but it does not substitute for an independent US administrative or judicial challenge.
