 By the 16th century, the writ was commonly used in the Court of Exchequer, although fairly strictly; when taking a case the Court would investigate whether there was any benefit to the King in hearing it, and if not would refer the case to another court.There was little interruption by the Court of Common Pleas, mainly due to their ongoing struggle with the Court of King's Bench over the Bill of Middlesex, which occupied most of their time.Wurzel suggests that the introduction and widespread use of this writ was not due to any arrogance on the part of the Exchequer, but rather because they felt that as "the most ancient" court they should have superior jurisdiction.
