“ An act of 1821 provided for sittings in chambers between terms, 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 1830 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 thereafter made. ”
