 The jurisdiction of the Court of King 's Bench , for example , was originally confined to pleas of the Crown , and then extended to actions where violence was used – actions of trespass , by force ; but now , all actions are admissible within its walls , through the medium of a legal fiction , which was adopted for the purpose of enlarging its authority , that every person sued is in the custody of the marshal of the court and may , therefore , be proceeded against for any personal cause of actions . Thus , by degrees , this court has drawn over to itself actions which really belong to ... the Court of Common Pleas . The Court of Common Pleas , however ... never was able to obtain cognizance of – the peculiar subject of King 's Bench jurisdiction – Crown Pleas ... the Exchequer has adopted a similar course for , though it was originally confined to the trial of revenue cases , it has , by means of another fiction – the supposition that everybody sued is a debtor to the Crown , and further , that he cannot pay his debt , because the other party will not pay him , – opened its doors to every suitor , and so drawn to itself the right of trying cases , that were never intended to be placed within its jurisdiction .
