Sanctions · OFAC · UN · EU
A sanctions designation can freeze every asset, close every bank account, and end every business relationship overnight — often without warning and based on intelligence the designated party has never seen. The consequences are immediate, severe, and rarely proportionate. The legal routes to challenge them are narrow but real.
Stradalex acts for designated individuals and entities across the three principal international sanctions architectures: OFAC (US Treasury), the UN Security Council, and the Council of the European Union.
Sanctions Regimes
Each sanctions architecture operates under different legal frameworks, with different standards of evidence, different procedural routes for challenge, and different timescales. Success requires expertise in all three — and an understanding of how they interact.
Administered by the Office of Foreign Assets Control within the US Department of the Treasury, OFAC sanctions are among the most far-reaching in the world. Any person or entity with a US nexus — any dollar-denominated transaction, any US correspondent bank, any US person or entity in the chain — is subject to OFAC jurisdiction. Designation on the Specially Designated Nationals (SDN) list effectively cuts a party off from the US financial system and, through secondary sanctions pressure, from much of the global financial system as well.
A formal petition to OFAC's Office of Global Targeting demonstrating that the basis for designation is factually incorrect, legally insufficient, or that circumstances have materially changed. OFAC has 90 days to respond. This is the essential first step and can result in delisting or modification of designation.
Where administrative reconsideration fails, an action for judicial review under the Administrative Procedure Act (5 U.S.C. § 706) may be brought in federal court. Courts review for arbitrary and capricious agency action; the evidentiary record before OFAC is central to the challenge.
Where full delisting is not immediately achievable, specific licences from OFAC can authorise particular transactions — enabling access to blocked funds for legal fees, humanitarian needs, or specific commercial activity while the substantive challenge proceeds.
Designated parties are entitled to receive the unclassified information OFAC relied upon and to respond. We engage this process aggressively, identifying factual errors, faulty source material, and misattributed conduct in the underlying intelligence.
The UN Security Council maintains fourteen active sanctions regimes, each administered by a dedicated committee and expert panel. Unlike OFAC or EU designations, UN listings bind all 193 member states simultaneously — and once listed, an individual or entity faces asset freezes, travel bans, and arms embargoes enforced across every UN member jurisdiction. The procedures for challenge are limited but not non-existent, and the Stradalex team has direct experience navigating them.
Available only for the Al-Qaida/ISIL regime, the Ombudsperson is an independent officer who conducts a comprehensive review of the listing and submits a recommendation to the 1267 Committee. A recommendation for delisting creates a strong presumption in favour of removal. This is the most effective procedural route available in UN sanctions law.
Established by UNSC Resolution 1730, the Focal Point receives de-listing petitions for all regimes other than 1267. Petitions are forwarded to the relevant sanctions committee, which reviews and decides. The process lacks the independence of the Ombudsperson but remains the primary formal channel.
Any UN member state may sponsor a de-listing request on behalf of a listed individual. We work with clients to identify the most strategically appropriate member state to advance the petition, and prepare the diplomatic-level submissions required.
In some jurisdictions, national courts have reviewed the compatibility of domestic implementing measures with constitutional or human rights standards. The ECtHR's decision in Nada v. Switzerland and the UK Supreme Court's A and Others provide important precedents.
EU sanctions are adopted by the Council of the European Union under the Common Foreign and Security Policy (CFSP) framework, implemented by Council Regulations that are directly applicable across all EU member states. Unlike US sanctions, EU designations are subject to review by the General Court of the European Union — an independent judicial body — making the EU system the most judicially accessible of the three. The Kadi jurisprudence of the Court of Justice has fundamentally shaped the rights of listed persons, establishing that they are entitled to judicial review regardless of the security context.
Under Article 263 TFEU, a listed person may bring an action for annulment before the General Court within two months of notification. Grounds include error of fact, inadequate statement of reasons, violation of the right to be heard, disproportionality, and breach of fundamental rights. The General Court has annulled numerous EU designations on these grounds.
A written submission to the Council of the EU requesting that the designation be reviewed and withdrawn. Unlike judicial proceedings, this is an administrative route that can be pursued in parallel with court proceedings and at any time. We prepare comprehensive review submissions addressing each element of the designation criteria.
Where designation causes immediate and irreparable harm, an application for interim measures (suspension of the designation pending the outcome of annulment proceedings) may be made to the President of the General Court. These applications require a showing of urgency and prima facie grounds for annulment.
Where implementing measures by member states go beyond the Council regulation, national courts may be seized. Preliminary references to the Court of Justice under Article 267 TFEU provide a further route to challenge the validity of the underlying EU listing.
In the largest single-matter result our team has obtained under OFAC's Russia-related sanctions programme, five separate clients designated under Executive Order 14024 were successfully delisted following comprehensive administrative reconsideration proceedings. All five were wholesale suppliers of microelectronic components — including field-programmable gate arrays, microcontrollers, and precision analogue components — whom OFAC alleged had knowingly contributed to Russia's drone weapons technology.
Executive Order 14024, signed in April 2021 and dramatically expanded following Russia's full-scale invasion of Ukraine in February 2022, authorises OFAC to designate individuals and entities determined to operate in Russia's technology and defence-industrial sectors, or to have materially assisted programmes that threaten the peace, security, stability, or sovereignty of Ukraine.
OFAC's enforcement focus on microelectronics reflects a documented pattern: components produced outside Russia — FPGAs, microcontrollers, guidance electronics, and signal processing chips — have been recovered from downed Russian weapons systems including Lancet loitering munitions, Shahed-series drones, and Kh-series cruise missiles. Faced with significant secondary sanctions pressure, OFAC moved aggressively to designate distributors and wholesalers in the supply chain, regardless of whether those entities had actual knowledge of the ultimate end-use.
Our five clients were commercial distributors operating in third countries. None had a direct relationship with Russian defence procurement entities. Their components had been sold to intermediaries representing them as legitimate civilian buyers. The intelligence underlying the OFAC designations conflated lawful commercial activity with intentional support for military programmes.
The reconsideration strategy
We obtained and analysed the unclassified administrative record provided by OFAC. The designation determinations cited commercial database records and transaction histories that, on examination, showed no direct sales to sanctioned Russian entities and multiple misattributed transactions — including sales to entities that had themselves been subsequently delisted.
We reconstructed the complete supply chain for each transaction identified by OFAC, producing contemporaneous purchase orders, end-user certificates, customs documentation, and buyer due diligence records. In each case, the documented end-use was civilian — telecommunications, industrial automation, and consumer electronics manufacturing.
The reconsideration petition addressed directly the question of knowledge: under EO-14024 and the Russia-related OFAC regulations, designation requires a finding that the party acted knowingly or had reason to know that goods would be diverted. We demonstrated that each client had implemented export control compliance programmes consistent with industry standards, and had no basis — on the information available to them — to anticipate diversion to Russian military programmes.
The petitions proposed enhanced compliance measures — expanded end-user verification, cessation of sales to identified high-risk jurisdictions, and third-party compliance auditing — demonstrating to OFAC that the risk its designation was intended to address had been independently addressed through structural changes in the clients' business practices.
All five clients were removed from the SDN list following OFAC's review of the reconsideration petitions. No judicial proceedings were required. The resolution of each matter at the administrative stage — without litigation — preserved the clients' ability to re-engage with US counterparties and the US dollar clearing system within the minimum practicable timeframe.
Stradalex
Sanctions work is time-sensitive. Deadlines for judicial challenge — two months before the General Court, strict APA limitations periods — run from the date of notification or publication, not from when legal advice is first sought. Early instruction allows the full range of remedies to remain open.
We have acted across OFAC, UN, and EU frameworks, in parallel and in sequence. Where a client faces designations across more than one architecture — as many do — the strategy must be coordinated. We bring that coordination to every sanctions mandate we accept.
