A designated individual or entity facing simultaneous UK and EU listings confronts two distinct evidentiary standards, two separate review timelines, and two procedural paths that rarely align. Which evidence package do you build first? How much does the OFSI standard differ from the EU General Court's approach? The answer to those questions determines whether a delisting petition succeeds or stalls.
Building the delisting evidence package under OFSI and under EU sanctions are related but materially different exercises. OFSI conducts an internal administrative review governed by the Sanctions and Anti-Money Laundering Act ("SAMLA") and the relevant thematic regulations, and its primary question is whether the designation criteria are still met. The EU General Court reviews Council designations through an annulment action, applying principles of proportionality and the right to effective judicial protection; the evidentiary threshold is adversarial and public. As of February 2026, practitioners advising on dual-track delisting must build two distinct packages – and the documents that carry weight in London do not always carry the same weight in Luxembourg.
This analysis maps each stage of the evidence-building exercise, identifies where the two regimes diverge, and sets out the risk flags that most commonly undermine a petition before it is lodged.
What is the governing authority and legal basis in each regime?
OFSI administers UK financial sanctions under SAMLA and the thematic regulations made under it. A designated person may apply to OFSI for a reassessment review, and if that fails, may seek a ministerial review and ultimately pursue judicial review before the High Court. The process is executive-administrative: OFSI applies internal evidentiary standards that are not fully published, and the designated person must work from the statutory designation criteria and any reasons disclosed on request.
The EU regime operates differently. The Council of the European Union designates persons under its autonomous sanctions regulations. A designated person may bring an annulment action before the EU General Court, which conducts a full merits review against the principle of proportionality and the right to a hearing. The Court's judgments are publicly reported, which creates a body of jurisprudence that practitioners can – and must – use to calibrate the evidence package.
That structural difference is consequential. OFSI is the judge of its own decision at first instance. The EU General Court is an independent tribunal with an adversarial procedure. In our experience, practitioners underestimate how much this shapes the documentary and legal-argument strategy at the package-building stage.
How does OFSI assess the evidentiary threshold for reassessment?
OFSI's reassessment review asks whether the grounds for designation are still met on the current facts. The designated person must therefore address both the original designation basis and any material change in circumstances since listing. Evidence that explains away the original grounds is as important as evidence of changed circumstances.
The OFSI process accepts written submissions, supporting documents, and – where disclosure has been made – representations addressing the specific reasons given. Where OFSI holds sensitive information it cannot disclose, the designated person is at an informational disadvantage. The evidence package must therefore be constructed to anticipate undisclosed grounds, drawing on all publicly available information about the programme and similar designations.
Practical evidence categories in an OFSI package include: a structured legal analysis of the designation criteria as applied to the individual's or entity's current circumstances; contemporaneous financial records establishing the absence of the activities cited; corporate governance evidence; and, where relevant, evidence of changed relationships with other listed persons. Witness statements from senior officers are routinely included but must be tightly drafted – any factual assertion that OFSI can contradict with its own intelligence undermines the entire submission.
Have you audited the original designation notice for every factual assertion? That audit is the starting point, not an optional step.
How does the EU General Court's evidence standard differ?
An annulment action before the EU General Court requires the applicant to demonstrate that the Council either lacked sufficient evidence to support the listing, applied the designation criteria incorrectly, or violated the applicant's rights – in particular, the right to effective judicial protection and the principle of proportionality. The Court has held, in its jurisprudence, that the Council must provide specific and concrete reasons for each designation; a general reference to a category of conduct is insufficient.
The evidence package for an EU annulment action is therefore structured around the Council's statement of reasons. Every factual assertion in that statement becomes a target for rebuttal. Documentary evidence must be contemporaneous, independently sourced, and capable of surviving cross-examination in a public hearing. The Court applies a standard of careful and impartial examination, meaning the applicant can compel the Council to produce its own evidence.
In our cross-border practice, we find that the EU package tends to require a heavier documentary burden than the OFSI package at first instance – but the EU route provides a clearer procedural roadmap, because the Court's existing jurisprudence sets out precisely what the Council must prove and where it has previously failed to do so. That jurisprudence is unavailable in the OFSI administrative track.
The Court also scrutinises whether the designation remains proportionate on current facts. Evidence of changed circumstances – reduction of economic activity, restructuring of ownership, changed relationships – can therefore be decisive in Luxembourg in a way that it may not be at the OFSI reassessment stage, where the threshold question is the narrower one of whether the criteria are still technically met.
Where do the two packages diverge most sharply?
The single sharpest divergence is procedural transparency. EU annulment proceedings are adversarial and on the public record. The Council must disclose the evidence it relied on (subject to confidentiality carve-outs), and the applicant can respond to it. OFSI is under no equivalent obligation; it may decline to disclose sensitive intelligence material, and there is no automatic right to see the evidential basis for the designation.
This has direct consequences for the evidence package. In an EU action, you build to the specific record. In an OFSI reassessment, you build to what you can infer, supplemented by any partial disclosure. A well-constructed OFSI package therefore includes an affirmative case – evidence that the criteria are not met – alongside a defensive case that pre-empts the most likely undisclosed grounds.
A second divergence is the relevance of changed-circumstances evidence. Under the EU proportionality principle, evidence that the applicant's current position no longer justifies a restrictive measure carries independent legal weight. Under OFSI, the question is more narrowly whether the designation criteria are still satisfied; proportionality arguments are less developed in the UK administrative track, though they remain available in a judicial review challenge.
Third, timelines differ materially. OFSI's internal review operates on a timeline set by the regulator, without a court-imposed timetable. EU General Court proceedings follow formal procedural rules with defined pleading stages; while the overall process is lengthy, each stage is structured and predictable. In a dual-track matter, those timelines rarely align, and a decision at one level can affect – and sometimes prejudice – the position at the other.
What are the common risk flags that undermine a delisting package?
The most frequent error is building the package around the designation notice alone, without mapping the full range of publicly available information that the regulator is likely to have considered. A package that addresses only the text of the notice leaves obvious gaps. Regulators do not decide solely on the face of the notice; they hold a broader evidentiary file, and a submission that ignores materials in the public domain reads as incomplete.
A second persistent risk flag is inconsistency between the legal submission and the supporting documents. If a witness statement asserts that a business relationship ended before a specified date, every document in the bundle – correspondence, financial records, corporate filings – must be consistent with that assertion. A single contradictory document does not merely undermine the point; it damages the credibility of the entire package.
Third, practitioners sometimes underestimate the importance of the ownership and control analysis. Where a designated individual has interests in corporate structures, the package must address every entity in the ownership chain, not only the listed person directly. Under the EU ownership and control test (the principle that an entity is caught where a listed person holds or controls it), failure to analyse the corporate structure in full can leave the delisting petition exposed to a counter-argument that the commercial position has not in fact changed.
A fourth risk is timing. In our experience, a petition lodged before the full evidentiary picture is assembled is rarely strengthened by a subsequent supplemental submission. A first-instance decision – whether by OFSI or the Council – that is refused on an incomplete record creates a precedent that colours every subsequent step, including High Court judicial review or EU General Court proceedings. The preparation phase is therefore not an administrative formality; it is the most consequential stage of the matter.
What position do you want to be in when the regulator's initial decision arrives? That question should drive the preparation budget, not the other way around.
The position above covers the standard framework for each regime. Your specific facts – the designation programme, the evidence base available, the commercial urgency, and whether a dual-track approach is warranted – change the analysis materially.

How do secondary-sanctions and cross-border complications affect the evidence package?
For a designated entity with US counterparties or US-dollar transactions, OFAC's position is a parallel consideration. The US SDN List (OFAC's list of Specially Designated Nationals and blocked persons) and the EU and UK lists are maintained independently, and a successful delisting in London or Luxembourg does not automatically remove a US designation. In a dual-track or triple-track matter, the evidentiary record built for one authority may be disclosed – voluntarily or through compelled process – to another.
Practitioners must therefore consider whether any admission made in an OFSI submission could be used against the designated person in a subsequent OFAC proceeding, and vice versa. Equally, a judicial review challenge in the UK High Court that produces a publicly reported judgment may be considered by EU counsel in drafting the annulment application, and may be cited by the Council in its defence. The evidence packages are legally distinct, but they are not factually isolated.
In a recent matter involving a holding company with operations across multiple jurisdictions, we were instructed to coordinate the OFSI and EU annulment evidence packages so that each was internally consistent with the other, while addressing the distinct evidentiary thresholds of each authority. The key deliverable was a master factual record – a single, verified source of truth for all factual assertions – from which jurisdiction-specific submissions were drafted. That approach eliminates the inconsistency risk that arises when separate teams work from separate document sets.
A secondary cross-border consideration arises where the designated entity has assets or relationships in Switzerland, Canada, or Australia. Each of those regimes operates its own review or appeal mechanism. The Swiss State Secretariat for Economic Affairs (SECO) administers its own sanctions ordinances; Canada's Global Affairs Canada (GAC) administers the relevant autonomous sanctions regime. An OFSI delisting does not bind SECO, and an EU annulment does not bind GAC. Building a multi-regime delisting strategy therefore requires a horizon scan at the outset, not an afterthought once the primary proceeding concludes.
If a transaction has already been blocked or an application has been refused in one regime, the time available to preserve options in the others narrows. Contact Calder & Vance at info@caldervance.com for an early review.
Addressing the common misconception: "the same package works for both regimes"
A persistent and damaging assumption in this area is that a single, consolidated evidence package can be submitted, with minor adjustments, to both OFSI and the EU General Court. That assumption understates the structural differences between the two authorities and the distinct standards they apply.
OFSI's review is administrative and executive. Its test is whether the designation criteria are currently met. The EU General Court's annulment procedure is judicial and adversarial, and its test encompasses proportionality, procedural rights, and the quality of the Council's evidence. A document-heavy annulment-style package lodged with OFSI may be processed as a reassessment submission but risks presenting arguments that OFSI has no legal basis to weigh in the same way. Conversely, an OFSI-style submission lodged before the EU General Court – lacking the adversarial structure and the criterion-by-criterion rebuttal – may fail on procedural grounds before its substantive merits are examined.
We regularly advise clients who have attempted a unified approach on the first submission and come to us after the first refusal. By that point, options have narrowed and the evidentiary record has been partially set. A separate, tailored package for each authority – designed to the specific evidentiary standard and procedural rules of that authority – is not a luxury; it is the minimum required for a submission with a realistic prospect of success.
