Shurat HaDin Files ICC War Crimes Complaint Against Spanish PM Sánchez Over Iran Arms Transfers
Israeli legal advocacy organization Shurat HaDin — the Israel Law Center — has filed a formal complaint with the International Criminal Court in The Hague against Spanish Prime Minister Pedro Sánchez, alleging complicity in war crimes through the authorized transfer of dual-use materials to Iran. The complaint centers on Spanish state-approved exports valued at approximately 1.3 million euros conducted during 2024 and the first half of 2025, a period that overlaps with accelerating Iranian regional operations and the lead-up to the February 2026 US-Israeli strikes on Iranian targets.
The Exports: What Spain Sent to Iran
The factual basis for the complaint is not disputed — it derives from Spain’s own official trade statistics. According to the Estadísticas españolas de exportación de material de defensa, de otro material y de productos y tecnologías de doble uso 2024, published by Spain’s Secretariat of State for Trade, total dual-use material exports to Iran for 2024 and the first half of 2025 amounted to €1,331,289.37.
The composition of those exports is what makes the complaint legally significant. The shipments included:
- Detonators and explosives classified under categories A, B, and E
- Laboratory reagents and control software with acknowledged dual military-civilian applications
- High-precision machine tools — specifically CNC lathes, milling machines, and machining centers — falling under Category 2 (“treatment of materials”), which accounted for €1,298,186 of the total
Category 2 precision machining equipment is tightly controlled under EU dual-use regulations precisely because it enables the manufacture of components for ballistic missiles, centrifuges, and nuclear device casings. The inclusion of detonator-type materials sharpens the legal exposure considerably.
This is not an isolated data point. Since Pedro Sánchez took office in mid-2018, Spain’s cumulative dual-use exports to Iran have reached nearly €6 million, according to official data covering through the first half of 2024. The transfers continued in full view of EU sanctions frameworks that explicitly ban exports to Iran of components usable in UAV and missile manufacturing.
The Legal Theory: Aiding and Abetting Under the Rome Statute
Shurat HaDin’s legal strategy targets Sánchez under the Rome Statute’s command responsibility provisions, specifically Article 28, which establishes criminal liability for military or civilian superiors who knew or should have known that subordinates were committing — or were about to commit — crimes, and who failed to prevent or repress them.
The argument runs as follows: Iran, as a designated state sponsor of terrorism under multiple jurisdictions, has used precision manufacturing capability, detonator technology, and dual-use components to arm Hezbollah, supply Houthi forces in Yemen, and develop drone and missile systems subsequently used against civilian and military targets across the Middle East. By authorizing the export of materials with a foreseeable path into those weapons programs, Spain’s government bears legal exposure as a material facilitator.
Shurat HaDin — founded and led by attorney Nitsana Darshan-Leitner — has a long record of deploying ICC complaints as instruments of strategic legal pressure. The organization has previously filed ICC communications against Hamas leadership, Palestinian Authority president Mahmoud Abbas, and the ICC’s own former prosecutor Fatou Bensouda. Its strategy is explicitly adversarial and counter-sue-oriented: use the court’s own procedures to expose political double standards while building a formal record even where prosecution is unlikely in the near term.
The Sánchez complaint follows that template. A sitting EU head of government from a Rome Statute member state is a cleaner jurisdictional target than a non-member like Iran. Spain’s membership in the ICC means Sánchez cannot invoke the same jurisdictional defenses Israel or the United States typically raise.
The Wider Political Context
The complaint lands at an acute moment in Spanish-Israeli-American relations. Since the onset of the US-Israeli military campaign against Iran beginning February 28, 2026, Sánchez has emerged as the most vocal Western critic of the operation, positioning Spain as the de facto anti-war anchor within NATO’s European flank.
Pedro Sánchez and his wife Begoña Gómez have been navigating a deepening corruption morass even before the Shurat HaDin complaint added an international legal dimension to his troubles. Gómez is under formal investigation by a Madrid court on charges of influence peddling and corruption in business dealings, accused of leveraging her husband’s position to secure contracts and endorsements for entities she was associated with — an investigation Sánchez has repeatedly dismissed as a politically motivated judicial attack. Sánchez himself has faced scrutiny over his brother David Sánchez’s publicly funded sinecure in the Extremadura regional government, a position critics described as a patronage appointment with no credible job description. The accumulating domestic legal pressure has already forced Sánchez into a brief suspension of government activity in April 2024 while he publicly deliberated whether to resign — ultimately choosing to stay — making him one of the most legally embattled sitting leaders in Spain’s recent democratic history.
Key markers of Spain’s posture:
- Sánchez condemned the strikes from day one as violations of international law, invoking the 2003 Iraq War as a historical cautionary parallel
- Spain denied the United States use of the Rota and Morón joint bases for offensive operations against Iran, resulting in the relocation of US refueling aircraft and trade threats from President Trump
- On March 11, 2026, Spain withdrew its ambassador from Israel
- On March 30, Spain closed its airspace entirely to US aircraft involved in the Iran campaign
- Defense Minister Margarita Robles described the conflict as “profoundly illegal and profoundly unjust”
Polling confirms broad Spanish public support for this posture: surveys conducted at the conflict’s outset showed more than two-thirds of Spaniards opposed US-Israeli military intervention.
But Sánchez’s “no to war” positioning is now colliding with the documented record of his government’s arms and dual-use material transfers to the regime his foreign policy is ostentatiously defending. That collision is precisely what Shurat HaDin is exploiting.
The EU Sanctions Problem
The exports occurred against a backdrop of tightening EU sanctions on Iran. Relevant controls in force during the export period include:
- A July 2023 EU ban on exports to Iran of components used in UAV or missile manufacture, extended through at least July 2026
- Ongoing EU arms embargo and restrictions on missile-related goods and technology under Council Decision (CFSP) 2023/2195
- Mandatory export controls on Category 2 precision machining equipment under EU dual-use regulations (Regulation 2021/821)
Spain’s export licensing body, the Interministerial Board for the Regulation of Foreign Trade in Defense and Dual-Use Material (JIMDDU), was responsible for authorizing these transfers. Whether the approvals were lawful under existing EU derogations — or whether the end-use certificates submitted were adequate — is a central factual question the ICC complaint will force into the record.
This is not Spain’s first brush with Iranian export control failures. In 2012, Spanish customs raided machine tool manufacturer ONA Electroerosion S.A. over suspected smuggling of nuclear-usable items to Iran in violation of international sanctions — a case subsequently referred to the UN Panel of Experts on Iran.
OSINT Assessment
The legal horizon. ICC complaints of this type rarely result in direct prosecution of heads of government. The more operationally significant outcome is the evidentiary record they create — forcing governments to account for export licensing decisions in a formal international legal forum and generating discoverable documentation useful in civil and parliamentary proceedings.
The jurisdictional leverage. Spain is a Rome Statute member. That distinguishes Sánchez from most targets of ICC complaints filed by pro-Israel legal organizations. A preliminary examination by the Office of the Prosecutor would carry diplomatic weight regardless of its ultimate outcome.
The domestic political dimension. Spain’s center-right and far-right opposition — Partido Popular and Vox — have already weaponized the Iran exports story in parliamentary proceedings. The Shurat HaDin complaint gives them an international legal peg for continued pressure.
The escalation risk. Sánchez closed Spanish airspace to US war planes on March 30. Trump has threatened trade retaliation. An ICC complaint against a sitting NATO prime minister, filed by an Israeli legal organization, adds yet another vector to what is already a multi-front deterioration of US-Spanish and Israeli-Spanish relations.
The arms-transfer pattern. The €6 million in cumulative dual-use exports to Iran under Sánchez since 2018 represents a consistent policy posture, not an isolated bureaucratic error. Parsing whether those exports violated EU sanctions law — as opposed to merely being politically damaging — requires granular review of what Category 2 equipment was exported in each period and against what end-use certifications.
The complaint is aggressive, adversarial, and calculated. Whether or not it advances to a formal ICC preliminary examination, it has already done part of its intended work: anchoring the dual-use transfer record into international legal proceedings and forcing the Sánchez government to defend its Iran trade posture in a forum where “no to war” rhetoric carries no weight.
