This raises the concern of multiple voting. Previous Venice Commission recommendations for Moldova have recommended that if supplementary voters lists are deemed necessary, one may consider the “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.”[19]
