A trading company operating across European and Asian markets receives notification that it has been added to an EU sanctions list. Its accounts are frozen. Contractual counterparties suspend performance. Correspondent banks withdraw. The designation notice offers little explanation. The company's management asks the obvious question: what can we do, and how quickly must we act?
A designated person or entity may challenge an EU designation through an annulment action (a legal challenge before the EU General Court seeking to set aside the listing decision) brought under the relevant Treaty provisions. The EU General Court reviews both procedural regularity and substantive sufficiency of evidence. As of February 2026, the Court has annulled a number of designations where the Council failed to provide adequate grounds or where the evidence did not meet the required standard.
This guide sets out the procedure, the legal tests, the critical deadlines, and the practical steps a designated party should take – from the first hour after notification through to a final judgment or a negotiated administrative review.
Step 1 – Understanding the legal basis for an EU designation and who administers it
EU sanctions designations are made by the Council of the European Union, acting under authority derived from the Treaty on the Functioning of the European Union and, where applicable, a UN Security Council resolution. The Council issues a Decision and a parallel Regulation. Both legal instruments must be in force for the listing to bite: the Decision provides political authority; the Regulation creates the directly binding legal obligations, including asset freezes and prohibitions on making funds available.
No single "sanctions authority" manages listings in the way that OFAC administers the SDN List in the United States. The Council's working groups propose listings; the High Representative's service provides analytical support; and individual member states may nominate persons for designation. Once listed, the designated party appears on the EU Consolidated List maintained by the European External Action Service.
Understanding this dual-instrument structure matters immediately. A challenge that successfully annuls the Regulation but not the Decision – or vice versa – may leave residual legal obligations in place across some member states. In our cross-border practice, we routinely advise clients to assess which instrument is the operative source of the restriction before settling the grounds of challenge.
The practical implication is structural: the Council acts as both decision-maker and defendant. It drafts the listing grounds, holds the evidence, and will defend the challenge in court. A designated party therefore faces a significant information asymmetry from the outset. Early legal advice – before the annulment window closes – is not a luxury. It is a procedural necessity.
Step 2 – How long do you have to act, and what triggers the deadline?
The time limit for bringing an annulment action before the EU General Court is two months and ten days from the date of publication of the listing in the Official Journal of the European Union, with a further extension for distance. This is a strict procedural deadline. Missing it forfeits the right to a direct challenge before the General Court, although other options – administrative review and relisting challenges – may remain open.
The two-month-plus-ten-day period is not measured from the date the designated party learns of its listing. It runs from Official Journal publication. A business that discovers its designation three weeks after publication has already lost three weeks of its window. The practical consequence is that monitoring for publication – whether by counsel, a compliance team, or an automated screening service – is as important as knowing what to do once a listing appears.
What happens if the Council amends or renews the designation? Each amendment or renewal that introduces substantively new grounds or evidence resets the limitation period with respect to those new elements. However, a renewal that merely continues a prior listing on unchanged grounds may not re-open a window that has already closed. We have advised clients who, having missed the initial deadline, sought to challenge a renewal: the analysis of whether genuinely new grounds are present is fact-specific and requires careful legal assessment.
One further timing point: a designated party may at any time submit a written request to the Council asking for a review of the listing. This administrative review is separate from judicial proceedings and does not suspend the limitation period. Pursuing only an administrative review while the annulment window closes is one of the most consequential procedural errors we encounter.
Step 3 – What grounds succeed before the EU General Court?
The EU General Court reviews an annulment action on four classic grounds: lack of competence of the institution; infringement of an essential procedural requirement; infringement of the Treaties or any rule of law relating to their application; and misuse of powers. In practice, designation challenges cluster around two of these: procedural infringement and substantive evidence.
On procedural grounds, the Court has consistently required that the Council state sufficient reasons for a designation. The statement of reasons must be specific enough to allow the designated party to understand why it was listed and to mount an effective defence. A generic reference to a person's association with a listed entity, without particulars, has been found insufficient in the Court's practice. How detailed is "detailed enough"? The answer turns on the specific facts asserted; but, as a benchmark, the statement of reasons must identify the conduct, role, or relationship that justifies the listing with enough precision for a court to verify it.
On substantive grounds, the Court applies a standard of review that requires the Council to provide, when challenged, information and evidence substantiating the listing grounds. The designated party may then dispute that information. The Court does not require proof to a criminal standard, but it does require that the evidence be reliable and specific to the individual or entity, and that it support the grounds stated in the listing notice. Evidence consisting entirely of press reports or general intelligence assessments, without corroboration, has proven vulnerable to challenge.
Rights of defence are a further ground. EU law requires that a designated party be given the opportunity to make observations, either before designation (where practicable) or immediately after. Where that right is denied or rendered meaningless by a failure to communicate the evidence relied upon, the Court has annulled listings. In our experience before the EU General Court, a combination of procedural and substantive grounds – where both the statement of reasons and the underlying evidence are deficient – gives the strongest basis for an annulment application.
Step 4 – Building the evidence package and presenting the challenge
An annulment action before the EU General Court is initiated by an application lodged at the Court Registry. The application must set out the pleas in law and the supporting evidence with sufficient precision. There is no second opportunity to add new pleas after the application is filed, except in limited circumstances involving matters that come to light later. The first filing is therefore the primary chance to present the full case.
Building the evidence package involves several parallel workstreams. First, obtain and analyse the listing grounds from the Official Journal notice and any accompanying statement of reasons. Second, identify the specific factual assertions and collect documentary evidence that contradicts, qualifies, or contextualises each. Third, assess whether any of the Council's stated grounds involve classified or restricted evidence – material the Court may review in closed proceedings without disclosing to the applicant. Fourth, map the procedural history: when was the applicant first notified, were observations invited, and was there any prior contact with the Council?
The evidence package for a designation challenge is not the same as a business-conduct defence. A company facing a criminal investigation marshals its evidence to prove innocence. A designated party before the EU General Court marshals its evidence to show that the Council's stated grounds either lack factual support, were procedurally defective, or cannot bear the legal weight placed on them. The standard is different; the strategy must reflect that difference.
In a recent matter, a financial-services business was designated on the basis of alleged support for a listed individual through a series of commercial transactions. We obtained and reviewed the Council's evidence bundle, identified that the key transaction records had been misread in translation, and prepared a corrected factual analysis supported by contemporaneous documentation. The application was lodged within the limitation period. The matter proceeded to a written phase of proceedings before the Court. We do not describe outcomes as guarantees, but the exercise of methodically testing each evidentiary plank against the original source material is the foundation of every effective annulment action we conduct.
Step 5 – Interim relief, parallel administrative review, and managing the designation period
Filing an annulment action does not automatically suspend the effects of the designation. Asset freezes remain in place. Interim measures (provisional relief granted by the Court's President while the main action is pending) are available in principle, but the test is demanding: the applicant must show urgency, a prima facie case, and that the balance of interests favours suspension. In practice, interim relief is rarely granted in sanctions cases, and a business should plan its legal and operational strategy on the assumption that restrictions will remain in force throughout the proceedings.
What operational steps are available? First, consider whether any specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) is available from the relevant national competent authority – the authority in the member state where the designated party or its counterparty is based. Licences exist for humanitarian payments, legal fees, and essential maintenance of assets; specific licences may be sought for other categories. This is a parallel track that does not require the judicial proceedings to be concluded first.
Second, submit a written request for administrative review to the Council. This gives the Council an opportunity to reconsider the listing, and may produce additional information about the evidence relied upon. The Council is required to respond. Even where the Council declines to delist, the review process can generate correspondence that is useful in the judicial proceedings.
Third, maintain detailed records of all impacts of the designation: frozen assets, terminated contracts, refused banking services, and any losses suffered. These records support any future delisting application, and in the event of annulment, form part of any argument about consequences. We regularly advise clients to maintain a running designation-impact log from the first day of listing.
Step 6 – After the General Court: appeal, re-listing, and the risk of renewal
A judgment of the EU General Court may be appealed on points of law to the Court of Justice of the European Union. The appeal route is available to both the applicant and the Council. An applicant who succeeds at the General Court should be aware that the Council may appeal; an applicant who loses may consider whether a pure point of law is arguable on appeal. Appeals on points of law alone are more restrictive than the original action; findings of fact by the General Court are generally binding.
What happens if the annulment succeeds? The listing is set aside. The Council must then decide whether to re-designate. Where it re-designates on different or supplemented grounds, the clock resets and a new challenge becomes necessary. This pattern – annulment followed by re-listing on revised grounds – has occurred in the Court's practice and represents one of the more challenging scenarios for a designated party's advisers. An effective response requires the original challenge to be framed in a way that anticipates the most likely revised grounds, so that subsequent challenges can be mounted efficiently.
Annual or periodic reviews of designations are built into many EU sanctions programmes. Even without a Court challenge, the Council must periodically review whether the conditions for listing continue to be met. A designated party that can demonstrate a change in circumstances – or that the original grounds have ceased to apply – may submit observations requesting delisting at the review stage. This is not a substitute for judicial challenge within the limitation period, but it is a meaningful parallel route that we use alongside litigation.
Cross-border considerations: how EU judicial review compares with OFAC and OFSI
The EU annulment process is structurally different from the routes available under the United States and United Kingdom regimes, and the differences affect both strategy and resource planning. Does the route available under your primary regime determine the overall strategy? Not necessarily – because a multinational or a financial institution may face parallel designations across regimes, and the grounds, timelines, and prospects of success can diverge sharply.
Under OFAC, a designated party may submit an administrative petition for reconsideration; there is no equivalent of a General Court annulment action as a first-instance judicial step. US federal courts can review OFAC decisions, but the standard of deference given to the executive branch is generally high, and the evidential threshold is demanding. The practical weight of the process falls on the administrative reconsideration petition. Counsel advising on a US challenge therefore structures the petition differently from an EU application: it must persuade the regulator, not a court, as the primary audience. For a comparative account, see our guide to challenging an OFAC designation.
Under OFSI in the United Kingdom, the designated party may request a ministerial review and then, if that fails, seek judicial review in the High Court of England and Wales. The High Court's judicial review applies principles broadly analogous to those used at the EU General Court – sufficiency of reasons, proportionality, procedural fairness – but the procedural rules differ, the limitation periods differ, and the standard of scrutiny that UK courts have applied has its own developing body of precedent. The interaction between an OFSI designation and an EU designation of the same party – which can occur – raises complex multi-regime questions about asset location and the applicable freeze obligations.
For parties seeking to understand the Australian regime's distinct administrative delisting process, our service page on building a delisting evidence package under the Australian regime sets out the specific documentation requirements. For the Japanese equivalent, our guide to designation challenges under the Japanese regime addresses the regulatory architecture and procedural routes available there.
One principle applies across all regimes: where the same transaction or conduct has generated designations in multiple jurisdictions, the evidence package and the legal arguments must be coordinated, not run independently. Inconsistencies between submissions to different regulators or courts can be exploited by the designating authority in each jurisdiction.
Risk flags: what weakens a challenge and when to involve counsel immediately
Several patterns consistently weaken EU annulment actions, and they are worth identifying before a challenge is filed rather than after. The first is delay. Every week lost after publication of the listing is a week lost from the evidence-gathering window. Where the statement of reasons is thin – as it frequently is in the first listing notice – that is not a reason for optimism; it means the Council's full evidence bundle will only emerge during proceedings, and the application must be constructed around the grounds as stated.
The second risk flag is over-reliance on the administrative review. Submitting an administrative request while allowing the two-month-plus-ten-day period to pass is a recurring error. Administrative review does not toll the limitation period. We have been instructed by clients who pursued only the administrative route and found themselves time-barred. The two tracks must run simultaneously, not sequentially.
The third risk concerns evidence preparation. A challenge that merely asserts the designated party is not what the Council says it is, without documentary support, will not succeed. The General Court applies a standard of review, not a standard of re-examination from scratch. The applicant must identify the specific defect in the Council's case – the missing factual link, the procedurally defective notification, the unreliable source material – and present evidence directed at that specific point.
A fourth risk arises in group structures. Where the designated party is an entity within a larger group, the designation of related entities – particularly under ownership and control principles (the EU test under which a non-listed entity may be treated as subject to restriction where it is owned or controlled by a listed person) – can affect other group members simultaneously. Understanding the full perimeter of the designation, across all affected entities and jurisdictions, must happen before the application is filed.
The most common myth we encounter is that a strong factual case will carry the challenge on its own. In practice, procedural grounds – inadequate statement of reasons, violation of rights of defence, failure to communicate evidence – are at least as important as substantive evidence grounds, and are sometimes easier to establish. A well-prepared challenge addresses both dimensions.
When should you instruct specialist counsel? Immediately upon notification – or immediately upon suspecting that a listing is imminent. Early instruction allows the evidence package to be assembled before the limitation period runs, preserves the option of interim measures if that analysis changes, and allows parallel tracks (administrative review, licensing applications) to be activated without delay. There is no procedural advantage to waiting.
