TheSacred Congregation of the Consulta orSacra Consulta was adicastery of theRoman Curia. It was set up as a 'special commission' bypope Paul IV in 1559 and officialised on 22 January 1588 byPope Sixtus V in thepapal bullImmensa Aeterni Dei.

It interpreted laws and resolved administrative, jurisdictional and feudal questions such as vassals' appeals against their barons regarding their feudal obligations. It acted as a supreme court for disputes between cities and their governors, making it a forerunner of the modernItalian Council of State.Pope Clement XII (1730–40) built thepalazzo della Consulta on the piazza del Quirinale as its headquarters, housing eight prelates, though the court actually held its sessions in thepalazzo di Montecitorio or in rooms in thePalazzo apostolico.[2]
