Council of State of Luxembourg

The Council of State (Luxembourgish: Staatsrot, French: Conseil d'État, German: Staatsrat) is an institution in Luxembourg that advises the national legislature, the Chamber of Deputies as well as the Government. Until 1 January 1997, it was also the country's supreme administrative court, but this function was ceded to the newly created Administrative Tribunal and Administrative Court.

The Council of State was created by King-Grand Duke William III in the Coup of 1856. It was originally entirely appointed by the Grand Duke, but this was changed in 1866, and, despite the roll-back of many changes brought about by the coup, the Council of State has otherwise remained.
