"The Heads of State or of Governrnent confirm their will, as expressed in the Copenhagen Declaration on the European identity, to ensure that the cherished values of their legal, political and moral order are respected and to safeguard the principles of representative democracy, of the rule of law, of social justice and of respect for human rights. The application of these principles implies a political system of pluralist democracy which guarantees both the free expression of opiniuns within the constitutional organization of powers and the procedures necessary for the protection of human rights" (Second Copenhagen Declaration, 1978)
