International Sanctions Removal Lawyers

Yes, lack of prior notification does not preclude a challenge and may strengthen it. Many sanctions regimes, particularly OFAC and EU measures, permit designation without advance notice based on concerns about asset flight. However, the European Court of Justice has repeatedly held that inadequate disclosure of reasons or evidence supporting designation violates fundamental rights of defence. A challenge can argue that the designating authority failed to provide a sufficient statement of reasons, that the evidence relied upon was never disclosed, or that the designation was based on outdated or inaccurate intelligence. These procedural deficiencies can form independent grounds for annulment.

The standard varies by regime but is generally lower than criminal proof. OFAC requires only ‘reason to believe’ based on credible evidence, while EU courts apply a ‘sufficiently solid factual basis’ test established in cases like Kadi II. The UK applies a ‘reasonable grounds to suspect’ threshold under the Sanctions and Anti-Money Laundering Act 2018. Crucially, the burden lies with the designating authority to justify the listing — not with the designated person to prove innocence. Successful challenges often demonstrate that underlying intelligence is stale, misattributed, or fails to establish the required nexus to sanctionable conduct.

Timelines vary significantly by jurisdiction and procedure. Administrative reviews before OFAC typically take 6–18 months, though complex cases extend longer. EU judicial challenges before the General Court average 18–30 months to judgment, with expedited procedures available in urgent cases. UK administrative review requests to OFSI should receive initial response within 28 days, but substantive reconsideration takes 3–12 months. UN Ombudsperson proceedings under the 1267 regime require approximately 8–10 months. During proceedings, interim relief applications can sometimes achieve partial asset access or travel permissions pending final determination.

No, each sanctions regime operates independently and requires separate challenge. Delisting from the EU Consolidated List does not affect OFAC SDN status, and vice versa. Even within the UN system, removal from Security Council lists does not automatically update national implementing measures. However, a successful delisting in one jurisdiction creates persuasive precedent and evidentiary material useful in parallel challenges. Coordinated multi-jurisdictional strategy is essential — particularly where the same underlying allegations form the basis for designation across regimes — to ensure delisting arguments are consistent and that favourable decisions are leveraged effectively elsewhere.

Yes, secondary sanctions — primarily a US tool — target non-US persons for conducting otherwise lawful business with designated parties. Under programs like CAATSA and Iran secondary sanctions, foreign companies and individuals risk being cut off from the US financial system, losing correspondent banking relationships, or facing their own designation for ‘significant transactions’ with sanctioned entities. Thresholds for triggering secondary exposure are often undefined, creating compliance uncertainty. Risk assessment requires analysing transaction volume, knowledge of counterparty status, and sector-specific guidance from OFAC, particularly regarding Russia and Iran-related dealings.
