"After much deliberation," says Lord Campbell, "I must express my clear conviction that the chancellor's equitable jurisdiction is as indubitable and as ancient as his common-law jurisdiction, and that it may be traced in a manner equally satisfactory. The silence of Bracton, Glanvil, Fleta, and other early juridical writers, has been strongly relied upon to disprove the equitable jurisdiction of the chancellor; but they as little notice his common-law jurisdiction, most of them writing during the subsistence of the _Aula Regia_; and they all speak of the Chancery, not as a court, but merely as an office for the making and sealing of writs. There are no very early decisions of the chancellors on points of law any more than of equity, to be found in the Year-books or old abridgments.... By 'equitable jurisdiction' must be understood the extraordinary interference of the chancellor, without common-law process or regard to the common-law rules of proceeding, upon the petition of a party grieved who was without adequate remedy in a court of common law; whereupon the opposite party was compelled to appear and to be examined, either personally or upon written interrogatories: and evidence being heard on both sides, without the interposition of a jury, an order was made _secundum æquum et bonum_, which was enforced by imprisonment. Such a jurisdiction had belonged to the Aula Regia, and was long exercised by parliament; and, when parliament was not sitting, by the king's ordinary council. Upon the dissolution of the _Aula Regia_ many petitions, which parliament or the council could not conveniently dispose of, were referred to the chancellor, sometimes with and sometimes without assessors. To avoid the circuity of applying to parliament or the council, the petition was very soon, in many instances, addressed originally to the chancellor himself." (Lives of Chancellors, i. 7.) In the latter part of Edward III.'s long reign this equitable jurisdiction had become, it is likely, of such frequent exercise, that we may consider the following brief summary by Lord Campbell as probable by analogy and substantially true, if not sustained in all respects by the evidence that has yet been brought to light:--"The jurisdiction of the Court of Chancery was now established in all matters where its own officers were concerned, in petitions of right where an injury was alleged to be done to a subject by the king or his officers in relieving against judgments in courts of law (lord C. gives two instances), and generally in cases of fraud, accident, and trust."
