It is for each country to decide how to improve gender equality in democratic institutions, including the Parliament.28 In the last decade, the Venice Commission observed that there was a growing number of States that have included gender quotas in their electoral legislation, and that quotas within candidates’ lists were preferred, as opposed to reserved seats in constituencies. It considered that, if legislative quotas were imposed, they should provide for at least 30% of women on party lists, while 40 or 50 were preferable in order to be effective.
