Abstract The International Court of Justice, to ensure friendly relationships between the international community, has recognized the importance of the principles of non-intervention and prohibited the use of force as a limit and guarantee of the sovereignty of nations. Nevertheless, during 2022 actions have been presented in the context of the Russia-Ukraine conflict that can be considered illegal inferences that involve the use of force. The present article aims to analyze the events that occurred during this conflict and contrast them with the international principles of non-intervention and prohibited use of force based on the ICJ jurisprudence and doctrinal approaches. In conclusion, the transgression of the analyzed principles by Russia against Ukraine is argued, which leads to the existence of international liability and the duty to repair and indemnify.
