If we started imposing quotas, where would we draw the line? That is the main issue. What is an acceptable quota? Having closed lists without quotas would definitely give political parties more power.
It is not a process that could be changed overnight, but if steps were taken to educate the public and increase their interest in politics, we believe that, over time, the lists would become more proportional and more representative of what the public really wants. For example, it is tricky for us to say that there has to be equal representation of men and women, that there have to be young people, and people from ethnocultural communities.
