ECtHR finds Ukraine responsible for 2018 acid attack on Kateryna Handziuk
The European Court of Human Rights ruled that Ukraine violated the rights to life and freedom of expression in the case of the 2018 acid attack on activist Kateryna Handziuk. The court found sufficient evidence linking the attack to the exercise or abuse of state power and ordered Ukraine to compensate her parents and partner.
Key points
- The ECtHR published its judgment in “Handziuk and Others v. Ukraine” on 5 November 2026.
- The court unanimously found violations of Article 2 (right to life) and Article 10 (freedom of expression).
- Ukraine must pay €40,000 jointly to Handziuk’s parents, Viktor and Nadiia Handziuk.
- Her partner Serhii Denysov must receive €40,000 in moral damages.
- Each of the three applicants is entitled to €4,000 for legal costs.
- The court found that the national investigation did not sufficiently examine possible additional perpetrators.
- Handziuk was attacked with concentrated sulfuric acid in Kherson on 31 July 2018 and died on 4 November 2018.
Why it matters
The judgment establishes state responsibility under the European Convention for Handziuk’s murder. It also recognizes that the planned and paid attack aimed to silence her public-control work and had a serious chilling effect on public discussion of corruption and abuses of power. The ruling highlights an investigative failure: Ukrainian authorities did not sufficiently examine the unresolved possibility that other people commissioned the attack.
What happened
On 5 November 2026, the European Court of Human Rights ruled in the case “Handziuk and Others v. Ukraine.” It unanimously held that the state had violated Article 2 of the European Convention on Human Rights, which protects the right to life, and Article 10, which protects freedom of expression. The court found sufficient, clear and consistent evidence of a close link between the attack and the exercise or abuse of state power, making Ukraine responsible. It described the 2018 assault as a planned and paid operation intended to force Handziuk to stop acting as a public controller. Ukraine must pay €40,000 jointly to her parents Viktor and Nadiia Handziuk and €40,000 to her partner Serhii Denysov, plus €4,000 to each applicant for legal costs. Although the court acknowledged that the national investigation identified and convicted the organizers and perpetrators and established the motive, it found that the authorities had not sufficiently and diligently checked the unresolved possibility of additional perpetrators.
How Ukrainian sources describe it
Ukrainian reporting centers on the court’s findings that Ukraine bears responsibility for violations of the rights to life and freedom of expression, along with the compensation awarded to the three applicants. It also presents the domestic investigation as substantial but procedurally deficient because possible additional perpetrators were not sufficiently examined. The coverage draws on the 2018 acid attack, Handziuk’s anti-corruption and public-control work, and subsequent convictions in Ukraine.
Where reporting differs
The applicants argued that Ukraine’s investigation was ineffective and did not establish responsibility for all the organizers. The government said the investigation was comprehensive and resulted in convictions of the direct perpetrators, intermediaries and organizers. The court acknowledged the investigation’s significant results but found procedural deficiencies, particularly its failure to examine the possibility of additional perpetrators. The government also denied that the attack could be attributed to the state and said Vladyslav Manger acted out of personal animosity outside his official powers. The court rejected that position, finding sufficiently strong, clear and consistent evidence linking the attack to the exercise or abuse of state power.
Background
Kateryna Handziuk was a Kherson municipal official, anti-corruption activist and public-control figure. She was attacked with concentrated sulfuric acid near her home in Kherson on 31 July 2018, suffered burns covering about 40% of her body, and died in Kyiv on 4 November 2018 after nearly three months of treatment. Five people were convicted in the domestic proceedings for organizing or carrying out the attack. In a separate 2023 ruling, a Kyiv court sentenced Vladyslav Manger and Oleksii Levin to ten years each for ordering and organizing it. Handziuk’s parents and partner subsequently brought the case before the European Court of Human Rights.
