Nothing in this Charter shall be interpreted as restricting or adversely affecting human rights and fundamental freedoms as recognised, in their respective fields of application, by Union law and international law and by international agreements to which the Union, the Community or all the Member States are party, including the European Convention for the Protection of Human Rights and Fundamental Freedoms, and by the Member States’ constitutions.
This provision is intended to maintain the level of protection currently afforded within their respective scope by Union law, national law and international law. Owing to its importance, mention is made of the ECHR.
