Other missions of the Ombudsman include: development and promotion of politician’s and government official’s ethics, investigation of the constitutional and judicial organization’s negligence to perform their duties or unlawful performance of their duties (excluding judicial proceeding of the courts); the monitoring, evaluation, and provision of recommendations on constitutional compliance and opinions on necessary constitutional amendment.
