The article addresses the issue of women’s representation in electoral legislation, focusing on the latest amendments of Chilean electoral laws. It first examines the conceptual relationship between representative democracy and equality, distinguishing between formal and substantive equality and representation, in order to fully understand the potential impact of electoral laws on women’s representation. A comparative perspective is then offered, showing the current representation of women in Parliaments and reviewing the connection with different features of electoral systems. In this context, gender quotas are analysed as one of the main mechanisms that have been used to increase women representation. Finally, the recent amendments of Chilean electoral law on this issue are presented, in order to anticipate what we can expect for women’s representation in the years to come.
