The term Grand Conseil (French pronunciation: [ɡʁɑ̃ kɔ̃sɛj]) or Great Council refers two different institutions during the Ancien Régime in France. It also is the name of parliaments in several Swiss cantons.
Starting in the 13th century, the "Grand Conseil" was the name given to the largest of the King's Councils, in contrast to the smaller and more elite "Conseil étroit" ("narrow council") or "Conseil secret".
Under Charles VII, a subcouncil of the King's council appeared to handle particularly contentious affairs. An ordinance by Charles VIII in 1497, and reissued by Louis XII in 1498, removed this section entirely from the King's Council and made it a superior court of justice under the institutional name "Grand Conseil". The "Grand Conseil" was not attended by the king, and it was furnished with its own legal and judicial personnel and with a purview over contentious affairs submitted directly to the king (affairs of "justice retenue", or "justice reserved" for the king). This removal of the Grand Conseil from the council apparatus permitted the remaining sections of the King's council to focus on political and administrative affairs.
The "Grand Conseil" had a jurisdiction over the entire kingdom, but could only be convoked by the king. The king sought the Grand Conseil's intervention in affairs considered to be too contentious for the parlement. The Grand Conseil was convoked on contentious issues pertaining to:
At its creation, the "Grand Conseil" was presided by the Chancellor of France, assisted by the maîtres des requêtes, and included several specialized officers (initially 17 consellors, increased to 20 (dividing their service in two semester) by Louis XII). Under Francis I, the positions of First President and four secondary (or so-called "mortar board" magistrates) "président à mortier" were added, and the chancellor ceased to preside over the court, other than in exceptional circumstances. In this way, the "Grand Conseil" slowly developed an internal structure similar to other sovereign courts of the realm. By the end of the Ancien Régime, the court consisted of a first president, eight presidents, 48 consellors, a prosecutor ("procureur général"), several attorneys (an ""avocat général" and eight substitutes), and various secretaries, baillifs and scribes.
