A trading company with operations spanning four continents receives notice that one of its directors has been designated under a major sanctions regime. The designation was made simultaneously by two authorities. The company's bank accounts in a third country are frozen the same morning. Its legal team faces an immediate question: which challenge route applies first, and do the criteria for designation differ enough between regimes to open a realistic ground of attack?
Challenging the designation criteria across a cross-border footprint means running separate, concurrent legal proceedings under different standards of review, against different authorities, on different timelines. As of February 2026, no single "global" review mechanism exists. Each regime – OFAC, OFSI, the EU Council, the UN Security Council committees – applies its own designation criteria, its own evidentiary threshold, and its own procedural rules. The practical consequence is that a successful challenge in one regime does not automatically remove the listing in another.
This guide walks through the criteria applied by each principal regime, the procedural routes available, the points of divergence that matter most in cross-border cases, the risk flags that arise when challenges proceed in parallel, and the stage at which specialist counsel becomes essential.
What are the designation criteria, and why do they differ?
Designation criteria are the legal tests an authority must satisfy before it places a person or entity on a sanctions list – and those tests vary materially between regimes. Under OFAC, the authority acts under IEEPA or the relevant programme-specific statute; it must find that the target meets the criteria set out in the applicable executive order. The standard is an administrative one: OFAC needs a "reason to believe" standard rather than a criminal burden of proof. Under OFSI, the Sanctions and Anti-Money Laundering Act ("SAMLA") requires that the Secretary of State have "reasonable grounds to suspect" the designation criteria are met. The EU Council issues designations by political consensus among member states, applying criteria set in the relevant Council Decision and Regulation.
These differences in the standard of proof shape every challenge. A body of evidence that defeats a "reasonable grounds to suspect" test in the UK may not defeat the corresponding EU standard, which in practice requires the annulling party to demonstrate to the EU General Court that the Council's factual basis was insufficient. In our cross-border practice, we treat these as analytically distinct proceedings even when the underlying facts are identical. The same director, the same alleged conduct, three different legal tests.
Step 1 – Map the designation landscape before filing anything
Before any petition or application is filed, the full designation picture must be mapped: which regimes have listed the target, which have listed connected entities, and whether any listing is derived from a UN Security Council resolution. A UN-derived listing under Chapter VII is the hardest to challenge directly; the primary route is the Focal Point for de-listing or, for ISIL and Al-Qaida designations, the Office of the Ombudsperson, which operates independently and can recommend delisting to the relevant committee.
Mapping also surfaces sequencing risk. Filing a petition with OFAC and simultaneously launching an annulment action at the EU General Court is usually both permissible and strategically sound. Filing a UK judicial review before the administrative review process under SAMLA is exhausted can, however, prejudice the litigation record. We regularly advise clients to run a sequencing analysis before any formal step is taken. This is not a formality: the order in which proceedings are filed, and the arguments deployed in each, can either assist or undermine parallel proceedings.
The mapping exercise should cover:
- Every regime that has designated the individual or entity
- Whether any listing is directly UN-mandated or autonomous (domestic-law-based)
- The date of each designation and any prior administrative review
- Connected listings – directors, shareholders, subsidiaries, affiliates
- Whether the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) or the equivalent ownership and control test (the UK and EU test for whether a non-listed entity is caught through a listed person) means that a separate entity is also effectively listed
The position above covers the standard case. Your facts – the regimes in play, the evidentiary record available, the business relationships at stake – change the analysis significantly. To begin a cross-border mapping exercise, contact Calder & Vance at info@caldervance.com.
Step 2 – Analyse the designation criteria and the evidentiary record in each regime
Each regime's designation criteria must be examined against the evidence the authority is likely to hold, and that evidence is rarely fully visible to the designated party at the outset. OFAC is not obliged to disclose the full administrative record at the challenge stage; the petitioner works from the public listing information and any unclassified material the agency releases. The EU General Court can order disclosure of the Council's file, and annulment actions under the relevant Council Regulation often turn on whether the Council had sufficient, specific, and concrete evidence for each criterion cited in the statement of reasons. Under SAMLA, OFSI must provide a statement of reasons, and the designated person can request a review; if that review is refused or unsuccessful, judicial review before the High Court remains available.
In practice, the EU annulment route before the General Court has produced the most developed body of case law on what constitutes adequate evidential basis for a designation. That jurisprudence – which does not bind OFAC or OFSI – nonetheless provides a useful analytical framework for stress-testing the evidence in any regime. The question to ask in every case is whether the authority can point to specific, concrete facts supporting each criterion, or whether the listing rests on association and inference alone.
Consider the following decision points:
- Does the statement of reasons identify a specific criterion (for example, a financing relationship, a management role, or an ownership link)?
- Is the evidence for that criterion current, or does it relate to a historical position that has since changed?
- Has the authority conflated the target with another person of the same or similar name?
- Does the criteria rely on a relationship with a third party whose own designation is separately challengeable?
Each affirmative answer to the last two questions indicates a potential ground of challenge. Each negative answer narrows the available arguments. Being rigorous at this stage prevents a poorly-evidenced challenge that weakens credibility before the authority.
Step 3 – Select the procedural route in each regime
The procedural route differs by regime, and in a cross-border matter the practitioner must hold multiple timelines simultaneously. Here is a working summary of the principal routes.
OFAC (US): A designated person submits a petition for administrative reconsideration. OFAC has broad discretion; it considers new information or changed circumstances. There is no fixed statutory deadline for OFAC to respond to a petition, and the process can extend over a considerable period. Judicial review in the US federal courts remains available where administrative remedies have been exhausted, but the courts historically give significant deference to the executive on sanctions matters.
OFSI (UK): The designated person may request a review of the designation under SAMLA. OFSI must consider that request and notify the outcome within a short statutory window. If the review is unsuccessful, an application for judicial review before the Administrative Court is the primary litigation route. Judicial review turns on public-law grounds: procedural error, irrationality, proportionality, and – under the Human Rights Act – Convention rights. The proportionality ground has proven significant in UK designation challenges.
EU General Court: An annulment action under the relevant Council Regulation must be brought within a defined period after the listing or after the claimant became aware of it. The General Court will examine whether the Council had a sufficient factual basis, whether the statement of reasons was adequate, and whether fundamental rights – including the right to property and the right to an effective remedy – were respected. In our experience advising on EU challenges, the adequacy of the statement of reasons is the first line of attack: an insufficient statement can itself ground an annulment.
UN Ombudsperson / Focal Point: For UN-listed individuals and entities, the Ombudsperson process (for ISIL/Al-Qaida listings) is the primary independent route. The Ombudsperson reviews the petition, gathers information from the petitioner and from member states, and makes a recommendation to the committee. The committee retains the final decision. For other UN list categories, the Focal Point mechanism transmits petitions to the relevant committee for decision. Neither route guarantees removal, and timelines can be lengthy.
How does the cross-border challenge differ from a single-regime challenge?
A cross-border designation challenge is not simply a single challenge multiplied. The practical complexity is qualitatively different. Arguments made in one forum become part of the public record that another forum can, and does, consider. A concession made in a US reconsideration petition – perhaps acknowledging a historical relationship to limit the scope of the dispute – can be deployed by the EU Council as confirmation of a criterion in the annulment proceedings. This is the documentation risk that practitioners often underestimate.
Resource sequencing is equally significant. Most cross-border challenges require specialist counsel in more than one jurisdiction, coordinated evidentiary disclosure, and a single consistent factual narrative across all proceedings. We have acted for clients where the challenge team included counsel advising on the US, EU, and UK proceedings simultaneously. The coordination overhead is real, and it begins on day one. Any inconsistency between the petitions – even a difference in the way a timeline is described – can create credibility issues that are difficult to resolve later.
A further dimension is secondary-sanctions risk. A successful delisting in one regime does not eliminate the extraterritorial reach of another. A company removed from an EU list may still face de facto restrictions if its US-person counterparties remain cautious about OFAC exposure. Secondary-sanctions risk – the risk that non-US parties conducting transactions outside US jurisdiction may nonetheless trigger US sanctions – requires a separate analysis even after a delisting is achieved.
If a transaction has already been flagged, or a filing has been refused, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com for a confidential preliminary assessment.
Risk flags in cross-border designation challenges
Several risk flags recur in cross-border matters. Recognising them early changes the outcome.
Cascade designations. When one regime lists a person and others follow within a short period, the temptation is to assume all listings rest on the same underlying evidence. That assumption is often wrong. Each authority conducted its own analysis; the evidence packages may differ; one may be more vulnerable than another. A challenge strategy that treats all listings as equivalent misses the weakest link.
Derived listings through ownership and control present a distinct risk. If the primary designation target is a company's parent, the subsidiary may be treated as subject to the same restrictions through the 50 percent rule (OFAC) or the ownership and control test (OFSI, EU). Challenging the subsidiary listing without addressing the parent designation is incomplete; the parent designation must also be addressed, or the subsidiary restriction revives the moment the challenge to it is resolved.
Timing asymmetry between regimes creates a further trap. EU annulment actions have short limitation periods. Missing that window – even by a small margin – is fatal to the direct litigation route; the alternative is then a review request, which carries less procedural force. OFAC petitions are not time-barred in the same way, but delay in filing allows adverse facts to accumulate in the administrative record. In our practice, we treat the first available review window in each regime as a hard deadline from day one of the engagement.
Reputational management is also a live risk. In high-profile cross-border matters, the designation itself attracts publicity, and the challenge proceedings may extend that publicity. Clients need a clear communication strategy that does not prejudice the legal proceedings. Statements made in the press can become exhibits in the formal proceedings.
Finally, watch for the interaction between designation challenge proceedings and civil litigation. If the designated person is simultaneously a defendant in civil proceedings – for example, asset-recovery litigation brought by a counterparty – the two proceedings intersect in ways that require careful management of the legal privilege position and the documentary record.
A common misconception addressed
A persistent belief in many compliance teams is that a successful challenge to one regime's designation will cascade automatically into delistings from the others. It will not. Each regime is legally independent. The EU General Court's annulment of a Council listing does not bind OFAC. OFAC's administrative removal of a designation has no direct legal effect on OFSI's position. The UN Security Council committee operates on a consensus basis among member states; a judicial outcome in a domestic court is a factor it may note, but it is not bound by it.
The practical consequence is significant. A business that obtains a successful annulment before the EU General Court – and assumes the matter is resolved – may find that its US dollar transactions remain blocked, that its UK bank accounts stay frozen, and that UN-derived restrictions continue. A full cross-border delisting requires parallel success, or at least parallel progress, across every relevant regime. There is no shortcut. We regularly advise clients at the outset that a "win" in one regime is a stage in the process, not the end of it.
