Discussion: The principle of equality before the law in the Indonesian legal system necessitates equal fulfillment of rights for both men and women, including the fulfillment of women's representation in legislative institutions. Currently, the fulfillment of women's representation as stipulated in Law Number 12 of 2003 is determined by considering the participation of women at a rate of 30%. However, this provision continues to present practical challenges. On one hand, the 30% quota has not been met as it consistently remains below 30%. On the other hand, the percentage of the 30% quota for women's representation established in the provision of Law Number 12 of 2003 has not been sufficient to realize gender equality in politics. Therefore, the purpose of this research is to assess the compatibility of the provision on women's representation in legislative institutions with the principle of the rule of law, and to analyze the legal protection relevance within the provision from the perspectives of legal justice and human rights.

Research Method: This research is of a juridical-normative nature, employing three approaches: the conceptual approach, the historical approach, and the statute approach. The analysis of this research is prescriptive in nature.
