The German occupiers abolished the Supreme Court in the General Government. In the Polish (non-German) judiciary sector, there was no court of the highest instance to ensure the unification of jurisprudence. The competence to ensure the uniformity of jurisprudence and resolve existing doubts and legal issues was transferred to the courts of appeal. The objective of the present article was to demonstrate the procedure and practice of issuing legal theses by the Court of Appeal in Kraków. The article also presents changes in the composition of the judges and the territorial jurisdiction of the Kraków Court of Appeal. Archival sources constitute the source basis of the work. We also resorted to the latest subject literature. The work is based mainly on the analysis of archival sources and legal acts, so the scientific methods typical of the history of law were applied.
