With open or free lists, voters may alter the ranking order of the list. If preference voting or cross-voting is possible, however, voters will not necessarily choose candidates from both sexes, and this may result in an unbalanced composition of the parliament, chosen by voters (CDL-AD (2002)023rev, Explanatory report, par. 25). Instead, open lists may work to the advantage of well-known male candidates. Thus, there is an inherent danger that the introduction of open lists may result in the election of fewer women.
