In 1297, Edward I confirmed the Magna Carta and other items. Judgments contrary to Magna Carta were nullified. The documents were to be read in cathedral churches as grants of Edward and all violators were to be excommunicated. He also agreed not to impose taxes without the consent of Parliament after baronial pressure had forced him to retreat from trying to increase, for a war in France, the customs tax on every exported sack of wool to 40s. from the 6s. 8d. per sack it had been since 1275. The customs tax was finally fixed at 10s. for every sack of wool, 2s. for each tun [casket] of wine, and 6d. for every pound's worth of other goods. The "tenths and fifteenths" tax levied on income from movables or chattels became regular every year. Edward also confirmed the Forest Charter, which called for its earlier boundaries. And he agreed not to impound any grain or wool or and like against the will of the owners, as had been done before to collect taxes. Also, the special prises or requisitions of goods for national emergency were not to be a precedent. Lastly, he agreed not to impose penalties on two earls and their supporters for refusing to serve in the war in France when the king did not go. Teh Magna Carta is the first statute. From 1299, statutes were recorded in a Statute Roll as they were enacted. By the end of the 1200s, the King's wardrobe, where confidential matters such as military affairs were discussed in his bedroom, became a department of state with the King's privy seal. The keeper of the privy seal was established as a new office by Edward I in 1318. The wardrobe paid and provisioned the knights, squires, and sergeants of the king and was composed mostly of civil servants. It traveled with the King. The Crown's treasure, plate, tents, hangings, beds, cooking utensils, wine, and legal and financial rolls were carried on pack horses or in two-wheeled carts drawn by oxen, donkeys, or dogs. The people in the entourage rode horses or walked. The other two specialized administrative bodies were the Exchequer, which received most of the royal revenue and kept accounts at Westminster, and the Chancery, which wrote royal writs, charters, and letters, and kept records. The chief functions of administration in the 1300s were performed by the council, chancery, wardrobe, chamber [room off wardrobe for dressing and for storage], and exchequer. Many of the chancellors had come from the wardrobe and chamber. In time, the chancellor ceased to be a part of the king's personal retinue and to follow the court. The chancery became primarily a department of central administration rather than a secretariat and record-keeping part of the royal household. The king used a privy seal to issue directives to the chancery. Edward III made some merchants earls and appointed them to be his ministers. He did not summon anyone to his council who did not have the confidence of the magnates [barons, earls, bishops, and abbots].
