"As to the nature of the rights thus enshrined in Article 3 (P1-3), the view taken by the Commission has evolved. From the idea of an "institutional" right to the holding of free elections (decision of 18 September 1961 on the admissibility of application no. 1028/61, X v. Belgium, Yearbook of the Convention, vol. 4, p. 338) the Commission has moved to the concept of "universal suffrage" (see particularly the decision of 6 October 1967 on the admissibility of application no. 2728/66, X v. the Federal Republic of Germany, op. cit., vol. 10, p. 338) and then, as a consequence, to the concept of subjective rights of participation - the "right to vote" and the "right to stand for election to the legislature" (see in particular the decision of 30 May 1975 on the admissibility of applications nos. 6745-6746/76, W, X, Y and Z v. Belgium, op. cit., vol. 18, p. 244). "
