The supplementary voters’ lists should not be allowed if a final register can be realised. If a mechanism for supplementary voters’ lists is still needed, it should be only tolerated if a mechanism for checking multiple voting should be introduced. Such a mechanism may include issuing of voters’ cards, or the introduction of double envelops for such votes. The double envelope has an outer one with the voter’s name and other data, which can be checked against other voters’ lists for multiple voting. After the check, the envelope is opened, and the ballot, inside a secrecy envelope, is only opened when the identity envelope is removed.
