The decision of the Constitutional Tribunal (CT) from October 2020 has severely curtailed women reproductive rights in Poland. Mass protests ensued. This paper focuses on the untold story of a productive rupture that channelled the protesters efforts into a mass legal mobilization against the CT judgment to the European Court of Human Rights (ECtHR). These applications, known as ‘Women’s Complaint’, were filed by over one-thousand Polish women. Triangulating between the analysis of interviews with human rights lawyers, feminist activists and the legal reasoning of the petition, I treat Women’s Complaint as a window into the Polish society as it provides unique glimpses into a society in deep conflict, embroiled in rule-of-law crisis, and exposes Law and Justice government’s ‘ruling by cheating’ strategies (as conceptualised by András Sajó). Women’s Complaint is about women standing for their reproductive rights and – in effect – spearheading a much broader rights-based litigation against the authoritarian backsliding.
