In order to comply with international standards, complaint and appeals procedures should clearly provide the right for voters, candidates and political parties to lodge electoral complaints. The Code of good practice in electoral matters does not develop extensively the categories of persons able to lodge electoral complaints, stipulating that “[a]ll candidates and all voters registered in the constituency concerned must be entitled to appeal. A reasonable quorum may be imposed for appeals by voters on the results of elections.” The Explanatory Report of the Code of good practice in electoral matters specifies however that “[s]tanding in such appeals must be granted as widely as possible. It must be open to every elector in the constituency and to every candidate standing for election there to lodge an appeal”, which should be interpreted as the possibility for other categories of persons involved in electoral processes to lodge electoral complaints as well. The European Court of Human Rights also accepts reasonable quorum requirements.
