The courts of equity may be said to have their origin as far back as the Aula or Curia Regis, the great court in which the king administered justice in person, assisted by his counsel- lors. Of the officers of this court, the chancellor was one of great trust and con- fidence, next to the king himself; but his duties do not distinctly appear at the pres- ent day. On the dissolution of that court, he exercised separate duties. On the introduction of seals, he had the keeping of the king's seal, which he affixed to charters and deeds; and he had some au- thority in relation to the king's grants,- perhaps annulling those which were alleged to have been procured by misrepresentation or to have been issued unadvisedly. As writs came into use, it was made his duty to frame and issue them from his court, which, as early as the reign of Henry II., was known as the chancery. And it is said that he exercised at this period a sort of equitable jurisdiction by which he mitigated the rigor of the com- mon law, to what extent it is impossible to determine. He is spoken of as one who "annuls unjust laws, and executes the rightful commands of the pious prince, and puts an end to what is injurious to the people or to morals," which would form a very ample jurisdiction; but it seems prob- able that this was according to the au- thority or direction of the king, given from time to time in relation to particular cases. He was a principal member of the king's council, after the conquest, in which, among other things, all applications for the special exercise of the prerogative in regard to matters of judicial cognizance were discussed and decided upon. In con- nection with the council, he exercised a separate authority in cases in which the council directed the suitors to proceed in chancery. The court of chancery is said to have sprung from this council. But it may be said that it had its origin in the prerogative of the king, by which he un- dertook to administer justice, on petitions to himself, without regard to the jurisdic- tion of the ordinary courts, which he did through orders to his chancellor. The great council, or parliament, also sent matters relating to the king's grants, etc., to the chancery; and it seems that the chancellor, although an ecclesiastic, was the principal actor as regards the judicial business which the select or king's council, as well as the great council, had to advise upon or transact. In the reign of Edward I. the power and authority of the chancel- lor were extended by the statute of West- minster 2d. In the time of Edward III. proceedings in chancery were commenced by petition or bill, the adverse party was summoned, the parties were examined, and chancery appears as a distinct court for giving relief in cases which required extraordinary remedies, the king having, "by a writ, re- ferred all such matters as were of grace to be dispatched by the chancellor or by the keeper of the privy seal." It may be considered to have been fully established as a separate and permanent jurisdiction, from the 17th of Richard II. In the time of Edward IV. the chancery had come to be regarded as one of the four principal courts of the kingdom. From this time its jurisdiction and the progress of its jurisdiction become of more impor- tance to us. It is the tendency of any system of legal principles, when reduced to a practical ap- plication, to fail of effecting such justice between party and party as the special circumstances of a case may require, by reason of the minuteness and inflexibility of its rules and the inability of the judges to adapt its remedies to the necessities of the controversy under consideration. This was the case with the Roman law; and, to remedy this, edicts were issued from time to time, which enabled the consuls and prætors to correct "the scrupulosity and mischievous subtlety of the law;" and from these edicts a code of equitable juris- prudence was compiled. So the principles and rules of the common law, as they were reduced to practice, be- came in their application the means of in- justice in cases where special equitable circumstances existed, of which the judge could not take cognizance because of the precise nature of its titles and rights, the inflexible character of its principles, and the technicality of its pleadings and prac- tice. And in a manner somewhat analo- gous to the Roman mode of modification, in order to remedy such hardships, the pre- rogative of the king or the authority of the great council was exercised in ancient times to procure a more equitable measure of justice in the particular case, which was accomplished through the court of chancery. This was followed by the "invention" of the writ of subpœna by means of which the chancery assumed, upon a complaint made directly to that court, to require the attend- ance of the adverse party, to answer to such matters as should be objected against him. Notwithstanding the complaints of the commons, from time to time,
