 As a result of reforming actions such as the Bill of Middlesex, the Common Pleas became increasingly conservative and resistant to King's Bench changes because of the impact they had on the business of the Common Pleas. This was best emphasised by Slade's Case, a struggle between the old and new forms of suing for breach of contract; although an equilibrium between the common law courts was finally reached, it eventually led to their dissolution with the Supreme Court of Judicature Act 1873, and merger into a single High Court of Justice.
