"Article 3 of Protocol No. 1 enshrines a characteristic principle of an effective political democracy and is accordingly of prime importance in the Convention system (see Mathieu-Mohin and Clerfayt v. Belgium, 2 March 1987, § 47, Series A no. 113). This Article would appear at first to differ from the other provisions of the Convention and its Protocols, as it is phrased in terms of the obligation of the High Contracting Parties to hold elections under conditions which will ensure the free expression of the opinion of the people, rather than in terms of a particular right or freedom. However, the Court has established that it guarantees individual rights, including the right to vote and to stand for election (ibid., §§ 46-51). "
