"The Court considers that the existence of a domestic system for effective examination of individual complaints and appeals in matters concerning electoral rights is one of the essential guarantees of free and fair elections. Such a system ensures an effective exercise of individual rights to vote and to stand for election, maintains general confidence in the State's administration of the electoral process and constitutes an important device at the State's disposal in achieving the fulfilment of its positive duty under Article 3 of Protocol No. 1 to hold democratic elections. Indeed, the State's solemn undertaking under Article 3 of Protocol No. 1 and the individual rights guaranteed by that provision would be illusory if, throughout the electoral process, specific instances indicative of failure to ensure democratic elections are not open to challenge by individuals before a competent domestic body capable of effectively dealing with the matter."
