Edward I, when he signed “Confirmatio Cartarum,” in an inconclusive way handed over to Parliament the right to consent to all taxation before it be levied; in other words, hereafter Parliament had grounds upon which it could contest arbitrary exactions of the crown. That the grounds for objection were not absolute and that Edward left a loophole by which he could escape will appear upon a consideration of the articles themselves. [The tax provisions of Confirmatio Cartarum] The first four chapters of Confirmatio Cartarum have to do with the bare reissuance of the Charter of Henry III, and penalties for their infraction. The fifth is more to the point; it provides that the recent exactions shall not be taken into precedent for future taxation.[183] The sixth chapter brings the issue directly before us and exhibits also the loophole by which the king might find his escape from it, if he should have the inclination and the power to do so. It says that “for no business from henceforth we shall take of our realm such manner of aids, tasks, nor prises, but by the common assent of all the realm, and for the common profit thereof, saving the ancient aids and prises due and accustomed.”[184] The chapter going on in reference to the evil custom of forty shillings on every sack of wool, commonly known as the “maletolt,” says, “We ... have granted that we will not take such thing nor any other without their common assent and good will; saving to us and our heirs the custom of wools, skins, and leather, granted before by the commonalty aforesaid.”
