A technology company incorporated in one jurisdiction, with banking relationships in three others, receives a letter confirming that it has been added to the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). Within hours, correspondent banks freeze accounts. Trade creditors suspend credit lines. The company's directors begin asking the same question: what do we do, and what do we need to prove?
Building the delisting evidence package under OFAC and OFSI compared reveals two processes that share a common objective – establishing that the designation basis no longer applies – but diverge sharply on procedure, evidence standard, and timeline. The OFAC administrative petition is submitted to the Office of Foreign Assets Control under IEEPA and reviewed internally; the OFSI reconsideration route operates under the Sanctions and Anti-Money Laundering Act and can be escalated to a ministerial review or, ultimately, judicial challenge in the UK courts. Getting the evidence package wrong in either jurisdiction does not produce a refusal only – it forecloses options that become harder to recover with time.
This analysis walks through the governing authority in each regime, the evidence standard each applies, the practical construction of the package, the points where OFAC and OFSI diverge most sharply, and the risk flags that counsel sees in submissions that fail. It is written for the compliance officer, the General Counsel, and the board member who needs to understand what delisting actually involves before instructing anyone to proceed.
What authority governs the delisting process under OFAC?
OFAC has the authority to delist – or "remove from the SDN List" – any person it has designated, and the administrative petition is the primary mechanism for seeking that outcome. The legal basis for OFAC designations sits in IEEPA and related executive orders; the reconsideration process is set out in OFAC's own regulations and published guidance. Crucially, there is no independent tribunal, no external adjudicator, and no statutory deadline within which OFAC must respond to a petition. The Office reviews the submission, may ask supplemental questions, and issues a decision on its own timeline.
That internal structure has a direct consequence for evidence strategy. Because OFAC is both the original decision-maker and the reviewing body, the petition must persuade the same institution that the basis for the original designation no longer holds. This is not a neutral appellate review. In our experience, petitions that treat the submission as a straightforward factual correction – rather than as a structured argument against a prior determination – tend to receive the least engagement from reviewers.
A secondary path exists in the US courts. A designated person may challenge a designation through the federal courts, arguing, for example, that the designation was arbitrary, capricious, or lacked sufficient process. That route operates in parallel to – not instead of – the administrative petition, and the interplay between the two tracks requires careful management. We regularly advise clients on whether to file a petition, initiate litigation, or pursue both simultaneously, and the decision depends heavily on the evidentiary position and the urgency of the client's commercial situation.
How does OFSI's reconsideration process differ from OFAC's petition route?
OFSI administers UK financial sanctions under SAMLA and the relevant thematic regulations, and the reconsideration route is formally structured in a way that the OFAC petition route is not. A designated person may request that OFSI reconsider the designation; OFSI then reviews the request and issues a reasoned decision. If that review is unfavourable, the designated person may escalate to a ministerial review – a second-tier look at the decision by a minister of the relevant department. Beyond that, judicial review in the UK courts is available, and the courts have shown willingness to scrutinise both the process and the evidence base on which a designation rests.
The structured two-tier administrative process at OFSI means that the evidence package must be calibrated across at least two distinct decision points, not one. What persuades a reviewing officer at the first stage and what a minister will find decisive at the second stage are not identical. In practice, this means the initial submission should be comprehensive enough to succeed at the first stage, while anticipating the ministerial-review framing if escalation becomes necessary.
There is also a material difference in the standard of justification OFSI must provide. UK courts have, in delisting matters, applied a standard of anxious scrutiny to the underlying evidence – a higher bar than the deferential standard that US federal courts have historically applied to OFAC's national-security determinations. This asymmetry matters for cross-border designees who are listed by both OFAC and OFSI simultaneously, because the UK route may offer a faster or more tractable path to removal, which can then be cited in the OFAC proceeding as additional evidence that the designation basis has been undermined.

What does a well-constructed delisting evidence package contain?
A delisting evidence package is not a statement of facts. It is a structured argument, supported by evidence, that the specific legal or factual basis for the designation no longer applies – or never applied correctly. The distinction matters, because regulators and courts assess whether the evidence addresses the designation ground, not whether it demonstrates that the designee is, in some general sense, a trustworthy business.
The core components of a well-constructed package are, in practice, consistent across both OFAC and OFSI, even where the procedure differs:
- A precise identification of the designation ground as stated in the public notice or in any disclosed materials. If the ground is vague or undisclosed, the package must address the most plausible interpretations of it.
- A factual rebuttal, supported by contemporaneous documentation, addressing each element of the stated ground. Corporate records, financial statements, board minutes, ownership registers, and transactional documents are the typical starting points.
- Third-party corroboration where available. Independent legal opinions, certified translations of foreign-law instruments, audited accounts, and regulatory clearance letters from other jurisdictions all carry weight.
- A compliance narrative demonstrating what the designee has done – and continues to do – to ensure that the conduct or relationship that triggered the designation has ceased or never existed. This forward-looking element is often underweighted by petitioners who focus exclusively on the past.
- A clear statement of the relief sought. This sounds obvious, but packages that blur the line between full removal and a specific-licence request create ambiguity that tends to produce the less favourable outcome.
One structural point that often escapes non-specialist teams: the evidence package is not a one-way transmission. Both OFAC and OFSI may issue supplemental questions, request additional documentation, or ask for a meeting. The package must be internally consistent enough to withstand that interrogation, because an answer given at the supplemental stage that contradicts the original submission damages credibility in a way that is difficult to repair.
Where do OFAC and OFSI diverge most sharply in their evidentiary demands?
The deepest divergence between OFAC and OFSI on building the delisting evidence package lies in what each institution treats as conclusive proof that a designation ground has been met or rebutted. OFAC operates in a national-security context in which classified or protected intelligence may underlie the designation, and the designee may never see the full factual basis. OFSI, operating under SAMLA and subject to UK public-law obligations, is required to disclose its reasons to a greater degree – though sensitive intelligence remains partially protected – and is subject to a more exacting standard of review if the matter reaches the courts.
This asymmetry has a practical consequence. In an OFAC petition, the evidence package must be strong enough to shift the internal assessment even when the petitioner cannot know every element of the original case against it. In an OFSI reconsideration, the package can be constructed more precisely around the disclosed grounds, and legal argument on proportionality and procedural adequacy carries more weight earlier in the process.
A second point of divergence is timing. OFAC does not publish statutory response timelines; the administrative process can run over an extended period, and applicants should plan for a process measured in months rather than weeks. OFSI operates under administrative-law obligations that create some expectation of timely response, and the ministerial-review stage adds a further tier but does not indefinitely defer resolution. Neither timeline is guaranteed, and in our practice we counsel clients to treat the process as open-ended while maintaining engagement with the reviewing body throughout.
A third divergence relates to the interplay with other regimes. Under OFAC, removal from the SDN List addresses only the US prohibition. A simultaneous EU listing, a UK listing, or a UN Consolidated List listing remains in force independently. Under OFSI, the same is true in reverse: a successful UK delisting does not remove the person from the SDN List or from an EU designation. For a designee listed across multiple regimes, the evidence packages must be coordinated but filed separately, with each addressed to the specific legal grounds of the relevant authority.
If a transaction has already been flagged, or a filing has been refused, an early review can preserve options that narrow with time. Write to Calder & Vance at info@caldervance.com for a confidential review.
What are the most common errors that cause delisting petitions to fail?
Inadequate address of the designation ground is the single most common failure. Petitioners who focus on establishing general commercial legitimacy – producing trading records, bank statements, and character references – without specifically engaging the stated or apparent basis for the designation present the reviewing authority with a large volume of evidence that does not directly rebut the charge. Volume is not persuasiveness. Precision is.
A second recurring error is conflating the delistng process with the licensing process. A specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) permits activity to continue despite a designation; a delisting petition seeks removal of the designation itself. Petitioners who request both simultaneously, without distinguishing the two in their submissions, often receive a specific licence and no action on the delisting – which may address the immediate commercial problem but leaves the underlying designation in place, with all its reputational and structural consequences.
Third: the ownership and control analysis is frequently incomplete. Where the designation turns on the designee's relationship to another listed person – ownership by a listed parent, or control of a listed subsidiary – the package must trace and document the ownership chain in full. A disclosure that omits a holding company layer, or that relies on a stale corporate register, creates a gap that the reviewing authority will identify and that undermines the credibility of the submission as a whole. The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) and the equivalent UK and EU ownership-and-control tests are not self-applying: they require documented analysis at each level of the structure.
Fourth, and perhaps most consequential for cross-border groups: failure to coordinate submissions across regimes. Where a group entity is listed by OFAC, OFSI, and the EU simultaneously, inconsistent factual narratives in three separate submissions create a record that any of the three reviewing authorities can use to question the petitioner's credibility. We have acted for multinational clients in exactly this situation, coordinating the submission of parallel evidence packages to multiple authorities while ensuring that the core factual narrative and the documentary record are consistent across every filing.
How does the cross-regime designation landscape affect evidence strategy?
For a business with operations in multiple jurisdictions, a single enforcement event – a designation by one authority – frequently triggers a cascade of secondary listings. An OFAC designation of a significant entity may prompt OFSI to consider its own listing; an EU Council designation may be mirrored in certain third-country regimes. The evidence strategy must account for this cascade, both because the grounds applied by different regimes may differ and because each authority will review its own listing on its own timeline.
The UN Consolidated List presents a distinct challenge. Listings by the Security Council committees are binding on all member states, and the only administrative route for most designees is through the Focal Point mechanism or, for ISIL/Al-Qaida-related listings, the Office of the Ombudsperson. The standard of review differs substantially from that applied by OFAC or OFSI, and the evidentiary demands of the UN process are not well served by a petition designed for the OFAC or the OFSI context. A package prepared for the Ombudsperson must engage the Security Council committee's evidentiary record, which is partially disclosed, and must frame the argument within the mandate of the Ombudsperson's review – a considerably narrower scope than the US or UK administrative processes.
In our cross-border practice, we treat the evidence package not as a single document but as a coordinated set of submissions, each adapted to the regime it addresses, each consistent with the others in its factual core. The discipline required to maintain that consistency – across different legal standards, different disclosure regimes, and different reviewing bodies operating on different timelines – is the central challenge in multi-regime delisting matters.
When is the evidence package strong enough to proceed?
No evidence package is guaranteed to succeed, and we do not promise outcomes. What counsel can assess is whether the package, on its current state, is capable of addressing the designation ground as stated; whether the documentary record is complete and internally consistent; whether the compliance narrative is credible and forward-looking; and whether the submission is correctly targeted to the relief sought.
A useful internal test before filing: would the package persuade a sceptical senior lawyer, reading it for the first time, that the specific legal basis for the designation is either unsupported or has been eliminated? If the answer is uncertain, the package is not ready. Adding more documents to an already voluminous but unfocused submission does not improve the position; restructuring the argument to address the designation ground precisely does.
There is also a question of timing. In some circumstances, filing a petition before the evidentiary position is fully developed can crystallise an adverse preliminary assessment that then becomes the default position of the reviewing authority. In others, delay causes commercial damage that cannot be reversed even if the delisting ultimately succeeds. The decision on when to file is a judgment call that depends on the specific facts, the urgency of the commercial situation, and the strength of the evidence then available. It is not a decision that should be made without experienced sanctions counsel reviewing the full picture.
Does your organisation have a realistic timeline, a complete evidence base, and a submission structure that directly addresses the designation grounds? If the answer to any of those questions is uncertain, that is the right moment to seek an independent review of the position.

A common misconception about the delisting evidence package
A widely held view is that delisting is primarily a legal argument – that the right lawyers making the right submissions will produce a removal regardless of the underlying facts. This is not the experience of practitioners who have submitted packages across multiple regimes. The legal argument frames and structures the evidence, but the outcome turns on whether the underlying facts, as documented, rebut the designation ground. A sophisticated legal submission built on a thin or inconsistent documentary record will not succeed. An evidentially robust record, competently presented, gives the best prospect of a positive outcome – not a certainty, but a genuine prospect.
The corollary is also true. A business that waits until the evidentiary position is perfect before filing may wait indefinitely, because the standard is not perfection but adequacy. The practical question is whether the package, as it currently stands, is capable of addressing the designation ground, and whether any gaps can be addressed during the supplemental-question stage rather than in the original submission. Getting that judgment right – filing at the right moment, with the right structure, for the right form of relief – is where experienced sanctions counsel adds the most measurable value.
In a recent matter, a financial-services business facing parallel OFAC and OFSI designations engaged Calder & Vance after an initial petition had been filed without legal assistance and had received no response for an extended period. We reviewed the submission, identified the gaps in the evidentiary record, filed a supplemental package addressing the designation ground directly, and coordinated engagement with both authorities. The matter ultimately resulted in the UK designation being removed ahead of the US one, which was then cited in the renewed OFAC engagement as additional evidence of the undermining of the designation basis. No specific outcome for any client is guaranteed, and every matter turns on its own facts.
Frequently asked questions on building the delisting evidence package: OFAC and OFSI compared
- Where do the regimes diverge on building the delisting evidence package?
The sharpest divergence is on disclosure, timeline, and the role of the courts. OFAC operates through an internal administrative petition with no statutory response deadline and limited disclosure of the underlying intelligence; a designated person may not know the full basis for their listing. OFSI must provide reasons to a greater degree under UK public-law obligations, operates a formal two-tier review with ministerial escalation, and is subject to more exacting judicial scrutiny. This means the evidence package must be structured differently for each authority: the OFAC submission must address the most plausible grounds even without full disclosure, while the OFSI package can be targeted more precisely at the stated reasons and can carry more explicit legal argument on proportionality and process.
- Which regime is stricter on building the delisting evidence package?
"Stricter" depends on the dimension assessed. OFAC is more opaque: classified intelligence may underlie the designation, and the designee operates with imperfect information about what it must rebut. US courts have historically applied a deferential standard to OFAC's national-security determinations, making judicial challenge more uncertain. OFSI is more procedurally demanding in the sense that its two-tier review requires a package robust enough to address two distinct decision-makers, and UK courts have applied closer scrutiny to the evidential basis of designations. For a designee listed by both authorities simultaneously, neither regime offers an easy path – but the approaches required are materially different, and conflating them is one of the most common and costly errors in multi-regime delisting work.
- What should a cross-border business do about building the delisting evidence package?
A cross-border business facing designation under OFAC, OFSI, or both should take three immediate steps: first, identify which regimes have designated it and on what stated grounds; second, preserve and organise the full documentary record relating to the conduct or relationship identified as the designation basis; third, obtain specialist sanctions counsel before filing anything. The first submission matters most – a poorly structured initial petition or a petition filed before the evidentiary position is ready can shape the reviewing authority's assessment in ways that are difficult to reverse. Cross-border coordination of parallel submissions is essential where multiple regimes are involved, and the submissions must be consistent in their factual core even where they differ in legal argument.
