CHAMBERS, in law, the rooms of counsel or of judges or judicial officers who deal with questions of practice and other matters not of sufficient importance to be dealt with in court. It is doubtful at what period the practice of exercising jurisdiction "in chambers" commenced in England; there is no statutory sanction before 1821, though the custom can be traced back to the 17th century. An Act of 1821 provided for sittings in cham bers in vacation, and an Act of 1822 empowered the sovereign to call upon the judges by warrant to sit in chambers on as many days in vacation as should seem fit, while the Law Terms Act, 183o, defined the jurisdiction to be exercised at chambers. The Judges' Chambers Act, 1867, was the first Act, however, to lay down proper regulations for chamber work, and the Judicature Act, 1873, preserved that jurisdiction and gave power to increase it as might be directed or authorized by rules of court to be there after made.
