In England, formerly, the highestcourt of judicature next to the Parliament, exercising jurisdiction at law, but chiefly in equity; but under the jurisdiction act of 1873 it became the chancery division of the High Court of Justice, and now exercises jurisdiction only in equity.
From French chancellerie, from Late Latin cancellaria, from Latin cancellarius, from Latin cancellus ("lattice") (English chancel), from Latin cancelli ("grating, bars"), from the lattice-work that separated a section of a church or court.
