The European Union’s General Court is now examining a legal challenge that raises fundamental questions about how far the bloc’s sanctions regime can reach into the operations of third-country businesses and family connections. On July 20, 2026, the EU’s Official Journal published details of a lawsuit filed by Alexander Andreyevich Zhdanov, a German businessman whose interests in the chemical trade have placed him at the center of a sanctions circumvention case .
The case, registered as Case T-459/26, targets Council Implementing Regulation (EU) 2026/509 of April 23, 2026, which added 37 individuals and 80 entities to the EU’s Russia sanctions list . Zhdanov’s challenge represents one of the more legally intricate disputes in the sanctions arena, touching on questions of jurisdiction over third-country operators, the evidentiary basis for sanctions, and the limits of familial association as grounds for designation.
The Sanctions Designation: What the EU Alleges
According to the official annex to Regulation 2026/509, Zhdanov was sanctioned because he is a limited partner in UrSeCo Handels GmbH & Co. KG, a German company that supplies high-purity hydrogen chloride (HCl) produced by Wacker Chemie AG to LLP “United Trading Group” in Kazakhstan .
The EU’s reasoning, as stated in the regulation, is as follows: United Trading Group then supplies this hydrogen chloride to the Russian company LLC “Siltron.” Zhdanov is the father of Alexander Zhdanov, the majority shareholder of LLC “Siltron” .
The Council’s stated basis for the listing is that, through his financial interests in UrSeCo Handels and his familial connection to the majority shareholder of Siltron, Zhdanov “participates in activities that circumvent the Union’s restrictive measures, specifically Article 3k (1) of Regulation (EU) No 833/2014” .
Under EU regulations, it is prohibited for Union operators to export hydrogen chloride to an entity in Russia . The sanctions were part of the EU’s 20th package, which the Council described as targeting the Kremlin’s military machine, energy revenues, and sanctions circumvention networks .
The Investigative Origins: Belarusian Report as the Catalyst
The sanctions against Zhdanov did not emerge from EU institutional investigations but from journalistic work. The designation followed a January 2025 investigation by the Belarusian Investigative Center (BIC), conducted in cooperation with the Organised Crime and Corruption Reporting Project (OCCRP).
The BIC investigation traced the supply chain of high-purity hydrogen chloride, a critical chemical used in semiconductor wafer processing. According to the report, German hydrogen chloride produced by Wacker Chemie was routed through Poland and Turkey to Kazakhstan, where United Trading Group served as the recipient. From Kazakhstan, the chemical was then supplied to Russian companies including Siltron and Elektronsnab .
Critically for the EU’s case, the investigation established that Siltron and UrSeCo Handels are owned by members of the same family. Alexander Andreyevich Zhdanov serves as managing director and holds 45% of UrSeCo Handels. In November 2023, a person with the same surname—Alexander Alexandrovich Zhdanov—provided a loan to Siltron, and on January 13, 2025, he became the owner of 90% of the company, according to Russian business database SPARK . The BIC concluded that the two Zhdanovs are likely father and son.
Zhdanov’s Legal Arguments: A Four-Pronged Challenge
According to the official notice published in the EU Official Journal, Zhdanov’s application to the General Court advances multiple pleas in law challenging both the substance and procedure of the sanctions designation.
Zhdanov argues that the Council failed to conduct a proper periodic review of his listing, rendering the statement of reasons unclear, vague, and insufficiently substantiated. He contends that the Council made an error of assessment and failed to discharge its burden of proof, asserting that the facts underlying his designation are “inaccurate and incomplete.” He further claims that the evidence relied upon by the Council is “outdated and unreliable” and does not substantiate the allegations against him .
A third plea alleges breach of essential procedural requirements, including violations of Article 16(2) TEU and the Council’s Rules of Procedure, as well as a breach of the right to good administration.
Finally, Zhdanov argues that the sanctions violate the principle of proportionality, contending that the Council failed to assess whether the measures remain “appropriate, necessary and proportionate” to their objectives and that the measures infringe his fundamental rights under Articles 16 and 17 of the Charter of Fundamental Rights .
The Core Legal Question: Can Family Ties Justify Sanctions?
Among Zhdanov’s central arguments is the contention that family relationships alone cannot serve as a sufficient basis for sanctions. The applicant asserts that his “familial connection with his son, who resides in Russia and is not included in the list, is not a sufficient basis for imposing sanctions”.
This argument strikes at a fundamental question in sanctions law: to what extent can the EU impose restrictive measures on individuals based on their association with others who may be engaged in prohibited activities? The Council’s position, as stated in the regulation, is that Zhdanov’s participation in sanctions circumvention arises not solely from his family ties but also from his financial interests in UrSeCo Handels, the company that supplied the hydrogen chloride to Kazakhstan .
The Broader Sanctions Context
Zhdanov’s listing was part of the EU’s 20th sanctions package, which the Council adopted on April 23, 2026. The package added 37 individuals and 80 entities to the sanctions list, including prominent figures in Russia’s military-industrial complex, cultural institutions, and media apparatus .
The regulation’s preamble cited the European Council’s December 2024 conclusions, which “reiterated its resolute condemnation of Russia’s war of aggression against Ukraine” and reaffirmed the EU’s support for Ukraine’s independence, sovereignty, and territorial integrity .
What Happens Next
The General Court will now consider Zhdanov’s application. If successful, the Council would be required to annul the sanctions as they apply to him.
The outcome could have implications beyond this single case, shaping how the EU approaches sanctions designations based on family connections and third-country business activities in future packages.
