The Interregnum granted some respite to the Common Pleas, which abolished fines on original writs, hurting the King's Bench, but in 1660 the fines were reinstated and "then the very attorneys of the Common Pleas boggled at them and carried all their finable business to the King's Bench". In 1661 the Common Pleas attempted to reverse this by pushing for an Act of Parliament to abolish latitats based on legal fictions, forbidding "special bail" in any case where "the true cause of action" was not expressed in the process. The King's Bench got around this in the 1670s; the Act did not say that the process had to be true, so the court continued to use legal fictions, simply ensuring that the true cause of action was expressed in the process, regardless of whether or not it was correct. The Bill of Middlesex disclosed the true cause of action, satisfying the 1661 statute, but did not require a valid complaint. This caused severe friction within the court system, and Francis North, Chief Justice of the Common Pleas, eventually reached a compromise by allowing such legal fictions in the Common Pleas as well as the King's Bench.
