A sanctions designation lands. Assets are frozen. Relationships are severed. Business stops. The instinct is to challenge the listing – but the route, the standard, and the realistic timeline differ sharply depending on whether the designating authority is the EU Council or the United States Office of Foreign Assets Control. Getting that comparison wrong at the outset can mean pursuing the slower route, the weaker ground, or the wrong court altogether.
Annulment actions before the EU General Court and OFAC's administrative reconsideration process are the two principal routes for challenging a designation in their respective regimes. As of February 2026, the EU route is a formal judicial proceeding before an independent court, with enforceable annulment as the remedy; the OFAC route is an administrative process before the same agency that imposed the designation, with judicial review available only after that process is exhausted. The evidentiary standards, the timelines, and the practical leverage each route provides diverge substantially.
This analysis examines the two procedures side by side – the legal basis, the grounds for challenge, the evidentiary requirements, the timelines, and the enforcement consequences – and draws out the practical implications for a designated person or a business holding assets on behalf of one.
What is an annulment action before the EU General Court, and who may bring one?
An annulment action before the EU General Court is a direct judicial challenge to a Council act – typically the regulation or decision adding or maintaining a person or entity on a sanctions list – on grounds that the act is unlawful. Any natural or legal person directly and individually concerned by the measure may bring the action. That standing test is relatively easy to satisfy for a named designee: the listing decision is, by definition, addressed to or individually affects that person.
The legal basis is the EU's primary law governing judicial oversight of Council acts. The General Court reviews the challenge on the record presented to it, including any classified or sensitive material supplied through the confidential procedure. It may annul the listing in whole or in part. If it does, the measure ceases to have legal effect, and the designee's name is removed from the relevant list. The Council may, however, re-list on corrected grounds – and in our experience, that risk must be factored into the litigation strategy from the outset.
Third-country persons – those who are not EU nationals or residents – are equally entitled to bring an annulment action, provided they are listed under an EU sanctions instrument. This extraterritorial reach of the EU court is a significant point: a designated entity incorporated outside the EU can bring judicial proceedings in Luxembourg.
How does OFAC's reconsideration process compare in structure and authority?
OFAC's delisting mechanism is administrative, not judicial. A designated person submits a reconsideration request directly to OFAC, and OFAC – the same agency that imposed the designation – reviews that submission and decides whether to de-list, maintain, or modify the designation. There is no independent adjudicator at this stage.
The legal basis for OFAC designations is typically IEEPA or TWEA, combined with the relevant executive order. OFAC's standard on reconsideration is whether the designee continues to meet the criteria for designation. That is a forward-looking inquiry: even if the original listing was procedurally imperfect, OFAC may maintain the designation on current grounds. This asymmetry – between challenging the original act and arguing the current state of affairs – has no equivalent in the EU annulment route, where the court reviews the legality of the act as adopted.
US federal-court challenges to OFAC designations are available but the standard of review applied by US courts has historically been highly deferential to the executive in national-security contexts. The standard is not equivalent to the EU General Court's substantive review. We regularly advise clients that the administrative reconsideration route is the necessary first step, and that court proceedings, if pursued, operate in a very different evidentiary environment from Luxembourg.
The position above covers the structural comparison. Your facts – the regime under which you are listed, the evidence available, the jurisdictions in which assets are held – change the analysis entirely.

On what grounds can a designation be challenged in each regime?
The EU General Court reviews designation decisions against a set of recognised legal grounds: manifest error of assessment (the factual basis is wrong or insufficient), procedural defects (inadequate disclosure, failure to state reasons, breach of rights of defence), breach of fundamental rights (including the right to property and the right to an effective remedy), and in some cases disproportionality. The court applies substantive scrutiny: it will assess whether the evidence on which the Council relied, properly evaluated, supports the designation criteria.
That scrutiny is real. The EU General Court has annulled designations where the Council relied on assertions without adequate corroborating evidence, where the stated reasons were insufficient to allow the designee to understand the case against them, and where the rights of the defence were not respected. In our cross-border practice, we have seen cases where the strength of the evidentiary record assembled by counsel made the difference between annulment and maintenance.
OFAC's reconsideration process does not apply grounds of review in the same formal sense. The designee submits information and argument to OFAC seeking to persuade the agency that the criteria for designation are not met or that the designation should be modified. There is no pleading of "manifest error" as such. The submission is more like a petition than a legal brief, although a well-structured factual and legal argument is plainly more effective than a bare assertion of innocence.
The practical consequence is important. In the EU, counsel structures the challenge around identifiable legal grounds and tests each element of the Council's stated reasoning. Before OFAC, counsel structures the submission around demonstrating changed circumstances, innocent ownership or conduct, or factual inaccuracy in the original designation narrative. The two skills – EU litigation drafting and OFAC petition writing – are distinct, and a client facing listings in both regimes simultaneously needs both.
Where do the regimes diverge on evidence and disclosure?
Disclosure is one of the sharpest points of divergence between the EU and OFAC routes. Before the EU General Court, the designee is entitled to the reasons for the listing. The Council must provide a statement of reasons that is sufficiently specific to allow the designee to understand the case against them and to mount an effective defence. Where sensitive material is involved, a confidential procedure exists, but the court itself reviews that material and assesses whether the non-disclosure is justified.
The court's ability to review classified material without full disclosure to the applicant is a procedural protection. It is not a complete solution. In practice, the adequacy of the reasons disclosed has been a productive ground of challenge: where the stated reasons are generic, internally inconsistent, or incapable of supporting the designation criteria, the court has been willing to intervene.
OFAC's approach to disclosure is substantially less generous. The designation is accompanied by a public narrative identifying the conduct or association that triggered the listing, but the underlying intelligence or third-party information supporting it is typically not disclosed. The designee must therefore work from the public-facing material, supplemented by their own records and investigation. This creates an asymmetry that the EU procedure – imperfect as it is – does not replicate to the same degree.
Record-keeping is relevant on both sides. A designee preparing a reconsideration to OFAC or an annulment petition to the General Court will need to assemble contemporaneous documentation of transactions, ownership structures, and counterparty relationships. This underscores a point we make consistently in our practice: even before a designation is challenged, maintaining clean and well-organised records is a material asset.
How long does each route realistically take?
The EU General Court annulment process is a multi-year undertaking in contested cases. From the filing of the application to a judgment, the proceedings can extend across two or more years in complex matters. Interim relief – an application to suspend the effects of the designation pending the outcome – is available but the test is demanding: the applicant must demonstrate urgency and a prima facie case. In our experience, interim suspension is granted only in cases where the financial or reputational harm is immediate and irreversible in a way that cannot be remedied by a later judgment.
The Council may, independently of the litigation, decide to de-list at a regular review – EU designations are subject to periodic review under the applicable sanctions instrument – and a de-listing in that process renders the annulment action moot. Counsel must therefore track both the litigation timetable and the Council's review cycle, and advise the client on which channel to prioritise at any given moment.
OFAC's administrative reconsideration does not carry a statutory deadline for a response from the agency. In practice, processing times vary and can run to many months or longer. Unlike the EU process, there is no formal interim-relief mechanism within the administrative channel: the designation remains in effect throughout. The absence of an independent adjudicator and the absence of a mandated timeline are the two practical features most consistently noted by practitioners advising designated persons.
If a transaction has already been frozen, or a business relationship has collapsed as a result of a designation, an early and structured review of the challenge routes can identify which procedural step will yield the first meaningful result in the shortest time.

What happens if the EU General Court annuls a listing?
An annulment by the EU General Court has immediate legal effect: the Council act, to the extent annulled, ceases to apply to the designated person. In practical terms, the name is removed from the relevant EU list, and the asset freeze and related prohibitions are lifted for EU-regulated counterparties.
Two complications arise consistently in our practice. First, the Council may re-list the person on corrected grounds. An annulment on procedural grounds – inadequate reasons, breach of disclosure – does not necessarily prevent a re-listing supported by a better-evidenced decision. A strategic annulment action must therefore anticipate the re-listing risk and, where possible, address the substantive grounds as well as the procedural ones. Winning on procedure alone may produce a short-lived result.
Second, an EU annulment does not affect designations under other regimes. A person de-listed by the EU Council remains on the OFAC SDN List – SDN List (OFAC's list of Specially Designated Nationals and blocked persons) – unless OFAC separately removes them. The same applies in reverse: an OFAC de-listing does not produce automatic EU relief. This asymmetry is one of the most practically significant features of the multi-regime environment. A business holding assets on behalf of a person listed by both the EU and OFAC must obtain separate relief in each regime before it can act freely.
The UK sanctions regime under OFSI operates similarly: a successful EU challenge does not produce automatic relief under UK law. Post-2021, the UK and EU lists have diverged, and the UK's own designation criteria and review mechanisms apply independently. Cross-border counsel must manage each regime as a separate track.
Common risk flags and mistakes in designation challenges
Is your challenge strategy calibrated to the right standard? Several patterns of error recur across the matters we advise on.
The first is treating the EU and OFAC routes as equivalent and applying the same document-assembly logic to both. They are not equivalent. The EU General Court is a court; the OFAC reconsideration is an administrative petition. The framing, the structure of the argument, and the evidentiary emphasis differ. A petition written for OFAC will not, without substantial adaptation, work as an EU annulment application.
The second is failing to identify and preserve the available grounds before the annulment window closes. The EU's primary law sets a time limit for bringing an annulment action from the date the applicant becomes aware of the measure. Missing that window extinguishes the direct judicial route. We advise all newly designated clients to treat the limitation period as the first and most urgent question.
The third is underestimating the re-listing risk. A partial victory – annulment on procedural grounds – followed by an immediate re-listing is not a win if the substantive basis of the designation remains intact. The strategy must address both dimensions.
The fourth is neglecting the interaction with other regimes. A business that obtains EU de-listing but remains on the OFAC SDN List will find that its US-dollar transactions, its US-person counterparties, and its financial-institution relationships remain disrupted. Relief must be pursued in each regime where the designation bites.
A common myth in this area is that an annulment action is essentially a formality once factual errors in the designation are identified. That is not so. The EU General Court applies a real standard, but it also gives the Council a margin of appreciation in foreign-policy and security contexts. An arguable case is not the same as a winning case. The outcome depends on the quality of the evidence assembled, the precision of the legal argument, and the specific grounds on which the Council acted.
When should a designated person involve sanctions counsel?
The answer is: immediately after the designation, and no later. The annulment window under EU law begins to run from a fixed point, and there is no discretion to extend it once it has passed. The first 48 to 72 hours after a designation lands should be spent identifying the listed instruments, the assets affected, the counterparties notifying the freeze, and the preliminary grounds of challenge – not drafting the petition, but mapping the position.
Counsel's role in the first phase is to assess whether a direct annulment action is viable, whether interim relief is arguable, whether a parallel OFAC or UK reconsideration is relevant, and whether any general licence or specific authorisation could permit urgent humanitarian or operational transactions while the challenge is pending.
In a recent matter, a trading company listed under an EU sanctions instrument found that its banking relationships across three jurisdictions were simultaneously suspended. We assessed the designation against the stated reasons, identified a procedural defect in the notification and an evidentiary gap in the Council's record, and prepared parallel submissions to the General Court and, via local counsel in the relevant jurisdiction, to the applicable national competent authority for an emergency operational licence. The matter illustrated how designation challenges and licensing applications are not alternative routes: they are often concurrent and mutually reinforcing strategies.
The decision matrix is straightforward in principle, harder in practice:
- Designation by EU Council only, with identifiable procedural defect → annulment action as primary route, with interim relief assessed; administrative review by the Council's own process as a parallel track.
- Designation by EU Council and OFAC simultaneously → parallel tracks required; EU litigation and OFAC reconsideration proceed independently; timing must be coordinated to avoid admissions in one forum that damage the other.
- Designation by OFAC only, assets primarily in the United States → administrative reconsideration as the necessary first step; federal court review assessed after reconsideration is concluded.
- Designation by OFSI (UK) only → separate petition under the UK regime; the EU General Court has no jurisdiction over UK OFSI designations post-2021.
Have you confirmed which regimes are active and which challenge windows remain open? That mapping exercise is the first step and cannot be skipped.
