One of the basic elements of world order is properly functioning legal systems of individual states. The Sars-Covid pandemic and armed conflicts around the world, including those involving Europe, have strained the certainty of legal transactions in the countries of the UN system and the need to seek new supranational solutions, especially in the field of international trade. The pillar of security is therefore becoming instruments of international law, with the World Trade Organization in mind. A special tool of this organization are the dispute settlement mechanisms to which member states must adhere. In the conducted research, the thesis was put forward that one of the guarantors of the security of legal transactions is the resolution of disputes using the basic legal tools of this organization. It was proved that disputes between states themselves become solvable if they are transferred to the WTO.
