Today, 27 March 2026, Ukraine, Canada, Sweden, and the United Kingdom jointly filed a counter-memorial against the Islamic Republic of Iran in the ongoing case before the International Court of Justice in relation to an appeal concerning the jurisdiction of the Council of the International Civil Aviation Organization (ICAO) under Article 84 of the Convention on International Civil Aviation (Chicago Convention).

The submission of this counter-memorial is a significant step toward ensuring justice for the victims of the PS752 tragedy and their families, and underscores the strong commitment of Ukraine, Canada, Sweden, and the United Kingdom to hold Iran accountable for its grave violations of international law.

On 17 March 2025, the ICAO Council confirmed its jurisdiction to consider the dispute concerning Iran’s violations of the Chicago Convention in connection with the downing of Ukraine International Airlines flight PS752 over Tehran on 8 January 2020 by military personnel of the Islamic Revolutionary Guard Corps.
