"The object and purpose of the Convention, which is an instrument for the protection of human rights, requires its provisions to be interpreted and applied in such a way as to make their stipulations not theoretical or illusory but practical and effective (see, among many other authorities, United Communist Party of Turkey and Others v. Turkey, 30 January 1998, § 33, Reports of Judgments and Decisions 1998-I; Chassagnou and Others v. France [GC], nos. 25088/94, 28331/95 and 28443/95, § 100, ECHR 1999-III; and Lykourezos v. Greece, no. 33554/03, § 56, ECHR 2006-VIII). The right to stand as a candidate in an election, which is guaranteed by Article 3 of Protocol No. 1 and is inherent in the concept of a truly democratic regime, would be merely illusory if one could be arbitrarily deprived of it at any moment. Consequently, while it is true that States have a wide margin of appreciation when establishing eligibility conditions in the abstract, the principle that rights must be effective requires that the eligibility procedure contain sufficient safeguards to prevent arbitrary decisions (see Podkolzina, cited above, § 35). This principle requiring prevention of arbitrariness is equally relevant in other situations where the effectiveness of individual electoral rights is at stake (see, mutatis mutandis, Kovach v. Ukraine, no. 39424/02, § 55, ECHR 2008). "
