The Chancery came to have a separate and independent equitable jurisdiction. It heard petitions of misconduct of government officials or of powerful oppressors, fraud, accident, abuse of trust, wardship of infants, dower, and rent charges. Because the common law and its procedures had become technical and rigid, the Chancery was given equity jurisdiction by statute in 1285. King Edward III proclaimed that petitions for remedies that the common law didn't cover be addressed to the Chancellor, who was not bound by established law, but could do equity. In Chancery, if there is a case that is similar to a case for which there is a writ, but is not in technical conformity with the requirements of the common law for a remedy, then a new writ may be made for that case by the Chancellor. These were called "actions on the case". Also, Parliament may create new remedies. There were so many cases that were similar to a case with no remedy specified in the common law, that litigants were flowing into the Chancery. The Chancellor gave swift and equitable relief, which was summary. With the backing of the council, the Chancellor made decisions implementing the policy of the Statute of Laborers. Most of these concerned occupational competency, for instance negligent activity of carriers, builders, shepherds, doctors, clothworkers, smiths, innkeepers, and gaolers. For instance, the common law action of detinue could force return of cloth bailed for fulling or sheep bailed for pasturing, but could not address damages due to faulty work. The Chancellor addressed issues of loss of wool, dead lambs, and damaged sheep, as well as dead sheep. He imposed a legal duty on innkeepers to prevent injury or damage to a patron or his goods from third parties. A dog bite or other damage by a dog known by its owner to be vicious was made a more serious offense than general damage by any dog. A person starting a fire was given a duty to prevent the fire from damaging property of others.
The king will fine instead of seize the land of his tenants who sell or alienate their land, such fine to be determined by the Chancellor by due process.
Only barons who were peers of the House of Lords were entitled to trial in the House of Lords. In practice, however, this pertained only to major crimes.
Treason was tried by the lords in Parliament, by bill of "attainder". It was often used for political purposes. Most attainders were reversed as a term of peace made between competing factions.
The King's coroner and a murderer who had taken sanctuary in a church often agreed to the penalty of confession and perpetual banishment from the nation as follows: "Memorandum that on July 6, [1347], Henry de Roseye abjured the realm of England before John Bernard, the King's coroner, at the church of Tendale in the County of Kent in form following: 'Hear this, O lord the coroner, that I, Henry de Roseye, have stolen an ox and a cow of the widow of John Welsshe of Retherfeld; and I have stolen eighteen beasts from divers men in the said county. And I acknowledge that I have feloniously killed Roger le Swan in the town of Strete in the hundred of Strete in the rape Property damage by a tenant of a London building was assessed in a 1374 case: "John Parker, butcher, was summoned to answer Clement Spray in a plea of trespass, wherein the latter complained that the said John, who had hired a tavern at the corner of St. Martin- le-Grand from him for fifteen months, had committed waste and damage therein, although by the custom of the city no tenant for a term of years was entitled to destroy any portion of the buildings or fixtures let to him. He alleged that the defendant had taken down the door post of the tavern and also of the shop, the boarded door of a partition of the tavern, a seat in the tavern, a plastered partition wall, the stone flooring in the chamber, the hearth of the kitchen, and the mantelpiece above it, a partition in the kitchen, two doors and other partitions, of a total value of 21s. four pounds, 1s. 8d., and to his damage, 400s. [20 pounds]. The defendant denied the trespass and put himself on the country. Afterwards a jury [panel]… found the defendant guilty of the aforesaid trespass to the plaintiff's damage, 40d. Judgment was given for that amount and a fine of 1s. to the King, which the defendant paid immediately in court." The innkeeper's duty to safeguard the person and property of his lodgers was applied in this case: "John Trentedeus of Southwark was summoned to answer William Latymer touching a plea why, whereas according to the law and custom of the realm of England, innkeepers who keep a common inn are bound to keep safely by day and by night without reduction or loss men who are passing through the parts where such inns are and lodging their goods within those inns, so that, by default of the innkeepers or their servants, no damage should in any way happen to such their guests … On Monday after the Feast of the Purification of the Virgin Mary in the fourth year of the now King by default of the said John, certain malefactors took and carried away two small portable chests with 533s. and also with charters and writings, to wit two writings obligatory, in the one of which is contained that a certain Robert Bour is bound to the said William in 2,000s. and in the other that a certain John Pusele is bound to the same William in 800s. 40 pounds … and with other muniments [writings defending claims or rights] of the same William, to wit his return of all the writs of the lord King for the counties of Somerset and Dorset, whereof the same William was then sheriff, for the morrow of the Purification of the Blessed Mary the Virgin in the year aforesaid, as well before the same lord the King in his Chancery and in his Bench as before the justices of the King's Common Bench and his barons of his Exchequer, returnable at Westminster on the said morrow, and likewise the rolls of the court of Cranestock for all the courts held there from the first year of the reign of the said lord the King until the said Monday, contained in the same chests being lodged within the inn of the same John at Southwark And the said John … says that on the said Monday about the second hour after noon the said William entered his inn to be lodged there, and at once when he entered, the same John assigned to the said William a certain chamber being in that inn, fitting for his rank, with a door and a lock affixed to the same door with sufficient nails, so that he should lie there and put and keep his things there, and delivered to the said William the key to the door of the said chamber, which chamber the said William accepted…
