This study aims to examine the development of judicial ethics, current legal regulations, and application areas within the judicial systems of Türkiye and the Turkish Republic of Northern Cyprus from a comparative perspective. Beyond legal knowledge, the preservation of ethical values in the administration of justice is a fundamental necessity for building public trust in the judiciary. In Türkiye, judicial ethics have been shaped primarily based on the Bangalore Principles of Judicial Conduct and institutionalized through the Judicial Ethics Principles of the Court of Cassation and the Declaration of Ethics of the Turkish Judiciary published by the Council of Judges and Surveyors. These regulations embody universal values such as independence, impartiality, integrity, and propriety.In the TRNC judicial system, the influence of the English legal tradition and the principles of equity form a unique structure in determining ethical standards. Under the TRNC Constitution and the Courts Law, the independence and impartiality of judges are under constitutional guarantee. This study analyzes the similarities and differences in ethical codes in both countries, discussing the protection of judicial independence, the strengthening of the right to a fair trial, and the effectiveness of oversight mechanisms against ethical violations. It emphasizes that in both legal systems, judicial ethics is not merely a set of professional rules, but a way of life befitting the honor of the judicial profession.
