"The Court reiterates that implicit in Article 3 of Protocol No. 1 are the subjective rights to vote and to stand for election. Although those rights are important, they are not absolute. In their internal legal orders the Contracting States make the rights to vote and to stand for election subject to conditions which are not in principle precluded under Article 3. They have a wide margin of appreciation in this sphere, but it is for the Court to determine in the last resort whether the requirements of Protocol No. 1 have been complied with. It has to satisfy itself that the conditions do not curtail the rights in question to such an extent as to impair their very essence and deprive them of their effectiveness; that they are imposed in pursuit of a legitimate aim; and that the means employed are not disproportionate (see Sadak and Others (no. 2) v. Turkey, nos. 25144/94 et al., § 31, ECHR 2002-IV). "
