Supplementary voter lists can enable persons to vote who have changed their address or reached the statutory voting age since the final register was published (CDL-AD(2002)023rev2-cor, part I.1.2.vi). Whilst increasing the inclusiveness of elections, however, supplementary lists may be extensively used for compensating for the inaccuracy of regular voter registration. This is problematic insofar as the use of supplementary lists increases the risk of multiple voting and of voting in the wrong districts. It should only be tolerated if sufficient safeguards against multiple voting are established.
