The authoress addresses in the article the debate concerning the application of quotas for the assertion of equal representation of men and women in politics. She develops the theoretical argumentation in order to disprove some objections formulated by Ivana Strilkova in her article 'Dilemmas of Positive Discrimination and Gender Mainstreaming as a Potential Solution?' published in Vol. 6, Nr 2 of this journal and abstracted in CEJSH. She based her argument on the theory of Nancy Fraser and Iris Young. With reference to some practical and empirical mentions she argues for efficacy of quotas for assertion of parity of participation between women and men. In particular, she alerts to dilemma of difference which is ground in the ambiguous relation between assertion of neutral rule and the threat of reification of group characteristics. Furthermore, she argues for the neutral formulation of quotas as a condition of minimal 40 % representation of each sex. Finally, she stands for inner political party quota instead of directive from above.
