The judicial branch plays an important role in decision-making. Its major institutions include the Supreme Court (''Sąd Najwyższy''); the Supreme Administrative Court (''Naczelny Sąd Administracyjny''); the Constitutional Tribunal (''Trybunał Konstytucyjny''); and the State Tribunal (''Trybunał Stanu''). On the approval of the Senat, the Sejm also appoints the ombudsman or the Commissioner for Civil Rights Protection (''Rzecznik Praw Obywatelskich'') for a five-year term. The ombudsman has the duty of guarding the observance and implementation of the rights and liberties of Polish citizens and residents, of the law and of principles of community life and social justice.
