Bunreacht na hÉireann, or the Constitution of Ireland, is the fundamental legal document that outlines the structure of the Irish government and the rights of its citizens. Adopted in 1937, it establishes the principles of democracy, the separation of powers, and the rule of law in Ireland. The Constitution consists of several articles that detail the functions of the Oireachtas (the national parliament), the presidency, and the judiciary. It also enshrines various rights, including civil liberties and social justice, reflecting the values and aspirations of the Irish people.
