On 22 October 2020, the Constitutional Tribunal of Poland ruled that an abortion due to foetal impairment was unconstitutional. This article discusses the context of this controversial ruling as well as its main tenets, focusing on the interpretation of the human rights proffered by the Tribunal and on the rule of law concerns raised by the Tribunal’s decision. Against the backdrop of a brief history of the legal regulation of abortion in Poland since 1945, the article offers a critical assessment of the human rights framework used in the Polish abortion debate. Based on a close reading of the Tribunal’s ruling and the dissenting opinions, the article points out the particularities in the Tribunal’s engagement with international law and human rights jurisprudence. The article argues that the Tribunal’s decision is yet another symptom of the crisis in which the rule of law in Poland has found itself since 2015. It bears evidence to the closing of the jurisprudential horizon caused by the political change which has been taking place in Poland since 2015, consisting of the reduction of the role of international human rights debates as a reference in Polish constitutional jurisprudence. The ruling is therefore a portent of Poland’s future compliance with its international commitments in human rights matters.
