Article 7 of the European Union Treaty on European Union outlines the process for addressing serious breaches of the EU's fundamental values by member states. It allows the EU to take action against a member state that is found to be violating principles such as democracy, rule of law, and human rights. The procedure can lead to sanctions, including the suspension of voting rights in the European Council. This mechanism is intended to protect the integrity of the EU and ensure that all member states adhere to shared values, promoting a cohesive and just union.
