That the Organization was established in the aftermath of World War II to bring nations and people together for the peaceful pursuit of science;

That Article II.1 of the Convention provides, inter alia, that “[t]he Organization shall have no concern with work for military requirements”;

That the core values of the Organization have always been premised upon scientific collaboration across borders as a driver for peace;

That aggression of one country by another runs against the values for which the Organization stands;

That all 23 of CERN’s Member States attending the emergency session of the United Nations General Assembly on 1 March 2022 voted in favour of UN Resolution A/ES-11/L.1 “deplor[ing] in the strongest terms the aggression by the Russian Federation against Ukraine in violation of Article 2 (4) of the Charter” and “deplor[ing] the involvement of Belarus in this unlawful use of force against Ukraine”; 



That Ukraine has been an Associate Member State of CERN since 2016, and Ukrainian scientists are active in many of the Organization’s experiments;

That the CERN Management and personnel, as well as the scientific community in CERN’s Member States, who are deeply touched by the widespread and tragic consequences of the aggression, are working to contribute to the humanitarian effort in Ukraine and to help the Ukrainian community at CERN;

That the CERN Management will comply with all applicable international sanctions;

The numerous members of CERN’s Russian scientific community who reject this aggression and with many of whom CERN has trustfully cooperated over the past years;

The military invasion of Ukraine by the Russian Federation, in violation of Article 2 (4) of the Charter of the United Nations; 



The people of Ukraine as well as the independence, sovereignty and territorial integrity of Ukraine;



The resulting loss of life and humanitarian impact;

The involvement of Belarus in this unlawful use of force against Ukraine;
