Three considerations that render the integration of Big Tech into the regulation of international justice inevitable.

The ongoing international armed conflict in Ukraine, following the aggression by Russia and Belarus, has re-evaluated the importance of new technologies at a dizzying pace. Overnight, every smartphone owner became a direct observer of the fighting in Ukraine, a volunteer in grassroots refugee aid, a founder of equipment for the Ukrainian armed forces, and a target in the information war. In my paper, I would like to elaborate on three modalities of new technologies that cannot be ignored in nowadays reality: digital evidence in criminal proceedings of war criminals, mean and method of warfare, and humanitarian aid facilitator. In discussing these issues, I would like to focus on some challenges regarding the conduct of Big tech companies as to their factual and legal cooperation with state and international authorities, and their role in providing international justice.
