Some doubts remain on the effectiveness of the complaints and appeals process for out-of-country voters. Article 149(2) still provides for submission of complaints via express mail while Article 67(9) provides for e-mail; these provisions should be harmonised, even if they do not concern the same type of violations. This could also lead to consideration as to whether to introduce the possibility for complaints and appeals by in-country voters to be done by post or e-mail.
