Regulation of trade became national instead of local. Trade was relatively free; almost the only internal transportation tolls were petty portages and viages levied to recoup the expense of a bridge or road which had been built by private enterprise. Responsibility for the coinage was transferred from the individual moneyers working in different boroughs to a central official who was to become Master of the Mint. The round half penny and farthing [1/4 penny] were created so that the penny needn't be cut into halves and quarters anymore.

Edward I called meetings of representatives from all social and geographic sectors of the nation at one Parliament to determine taxes due to the Crown. He declared that "what touches all, should be approved by all". He wanted taxes from the burgesses in the towns and the clergy's ecclesiastical property as well as from landholders. He argued to the clergy that if barons had to both fight and pay, they who could do no fighting must at least pay. When the clergy refused to pay, he put them outside the royal protection and threatened outlawry and confiscation of their lands. Then they agreed to pay and to renounce all papal orders contrary to the King's authority.

The Model Parliament of 1295 was composed of the three communities. The first were the lords, which included seven earls and forty-one barons. Because of the increase of lesser barons due to a long national peace and prosperity, the lords attending were reduced in numbers and peerage became dependent not on land tenure, but on royal writ of summons. The great barons were chosen by the king and received a special summons in their own names to the council or Parliament. Others were called by a general summons. The second community was the clergy, represented by the two archbishops, bishops from each of eighteen dioceses, and sixty-seven abbots. The third community was the commons. It was composed of two knights elected by the suitors who were then present at the county court, two burgesses elected by principal burgesses of each borough, and two representatives from each city. The country knights had a natural affinity with the towns in part because their younger sons sought their occupation, wife, and estate there. Also, great lords recruited younger brothers of yeoman families for servants and fighting men, who ultimately settled down as tradesmen in the towns. The country people and the town people also had a community of interest by both being encompassed by the county courts. The peasants were not represented in the county courts nor in Parliament. One had to have land to be entitled to vote because the landowner had a stake in the country, a material security for his good behavior.

Parliaments without knights and burgesses still met with the king. But it was understood that no extraordinary tax could be levied without the knights and burgesses present. Ordinary taxes could be arranged with individuals, estates, or communities. The lower clergy ceased to attend Parliament and instead considered taxes to pay to the king during their national church convocations, which were held at the same time as Parliament. For collection purposes, their diocesan synod was analogous to the count court. The higher clergy remained in Parliament because they were feudal vassals of the king.

Edward's council was the highest tribunal. It comprised the chancellor, treasurer and other great officers of state, the justices of the three courts, the master or chief clerks of the chancery, and certain selected prelates and barons. The council assisted the king in considering petitions. Most petitions to the King were private grievances of individuals, including people of no social rank, such as prisoners. Other petitions were from communities and groups, such as religious houses, the two universities, boroughs, and counties. These groups sometimes formed alliances in a common cause. Women sometimes petitioned. From 1293, the petitions were placed in four stacks for examination by the King and council, by the Chancery, by the Exchequer, or by the justices. Many hours were spent hearing and answering petitions. From 1305, the petitions were presented to the king in full Parliament.

The king still exercised the power of legislation without a full Parliament. He might in his council issue proclamations. The Chief Justices still had, as members of the king's council, a real voice in the making of laws. The king and his justices might, after a statute has been made, put an authoritative interpretation upon it. Royal proclamations had the same force as statutes while the king lived; sometimes there were demands that certain proclamations be made perpetual by being embodied in statutes, e.g. fixing wages. There was no convention that agreement or even the presence of representatives was required for legislation. The idea that the present can bind the absent and that the majority of those present may outvote the minority was beginning to take hold. Edward I's councilors and justices took an oath to give, expedite, and execute faithful counsel; to maintain, recover, increase, and prevent the diminution of, royal rights; to do justice, honestly and unsparingly; to join in no engagements which may present the councilor from fulfilling his promise; and to take no gifts in the administration of justice, save meat and drink for the day. These were in addition to other matters sworn to by the councilors.

Parliament soon was required to meet at least once a year at the Great Hall at Westminster beside the royal palace. London paid its representatives 10s. per day for their attendance at Parliament. From the time of Edward II, the counties paid their knight- representatives 4s. daily, and the boroughs paid their burgess- representatives 2s. daily. When it convened, the Chancellor sat on the left and the Archbishop of Canterbury on the right of the king. Just below and in front of the king his council sits on wool sacks brought in for their comfort from wool stored nearby. It answers questions. Behind them on the wool sacks sit the justices, who may be called upon to give legal advice, e.g. in framing statutes. Then come the spiritual and lay barons, then the knights, and lastly the elected burgesses and citizens. Lawmaking is now a function of Parliament, of which the King's council is a part, instead of a function of the king with his council and justices. The common people now had a voice in law-making, though legislation could be passed without their consent. The first legislation proposed by the commons was alteration of the forest laws governing the royal pleasure parks. Such a statute was passed in a bargain for taxes of a percentage of all movables, which were mostly foodstuffs and animals. The king offered to give up the royal right to tax merchandise for a new tax: customs on exports. The barons and knights of the county agreed to pay an 11th, the burgesses, a 7th, and the clergy a 10th on their other movables. In time, several boroughs sought to be included in the county representation so they could pay the lower rate. This new system of taxation began the decline of the imposition of feudal aids, knights' fees, scutages, carucage, and tallage, which had been negotiated by the Exchequer with the reeves of each town, the sheriff and county courts of each county, and the bishops of each diocese.

The staple [depot or mart, from the French "estaple">[ system began when the export of wool had increased and Parliament initiated customs duties of 6s.8d. on every sack of wool, woolfells [sheepskin with wool still on it], or skins exported in 1275. These goods had to be assessed and collected at certain designated ports. Certain large wool merchants, the merchants of the staple, were allowed to have a monopoly on the purchase and export of wool. Imports of wine were taxed as tunnage as before, that is there was a royal right to take from each wine ship one cask for every ten at the price of 20s. per cask.

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.

From 1299, statutes were recorded in a Statute Roll as they were enacted.
