The Constitution of Ireland is Bunreacht na hEireann, the basic law of the state. Adopted by referendum in 1937 it defines Ireland as a sovereign, independent and democratic state. It sets out the administrative structure of the Government and states that all powers of the Government derive under God from the people. It defines the structure and principles of legal and social policy to guide the Oireachtas (Parliament.) The rights of every citizen are also enshrined in the constitution.
