The Government is responsible to the parliament; some other institutions, such as the Croatian National Bank and the State Audit Office, also report directly to the parliament. The parliament appoints an ombudsman to promote and protect human rights and liberties established by the constitution, parliamentary legislation and treaties adopted by Croatia. The ombudsman is appointed for an eight-year term; the ombudsman's work is independent. The ombudsman, as well as all other persons authorised to act on behalf of the parliament, is granted parliamentary immunity equal to that enjoyed by parliamentary members.
