Royal Decree No. 35/2022 on the organization of the administration of justice, which transformed the "Administrative Court of Justice" into trial and appeal chambers within the ordinary courts, implicitly abolishing the Administrative Court of Justice from the Omani judicial system, where the judicial facility was reorganized. Since the issuance of this Decree, the Omani judicial system has applied the unified justice system, which is intended to have a single judicial authority in the State whose jurisdiction includes the consideration of all kinds of disputes, whether between individuals themselves or between individuals and government administrators, and whether they relate to administrative, civil or commercial matters. Prior to the above-mentioned decree, the Sultanate followed the dual judiciary, which is intended to have two independent jurisdictions. One of which will deal with administrative disputes between government administrative bodies and individuals, called administrative justice. This transformation will inevitably have implications this study will explain and analyze.
