 It was to facilitate the obtaining of money grants that Edward I endeavoured once more to unite representatives of the clergy and laity in one deliberative assembly, composed on the basis of temporal property.To have countenanced the attempt would have been to recognize the Crown's claim to tax church property, and the clergy insisted upon their constitutional right of making their money grants in Convocation.The struggle between the Crown and the clergy continued until 1337, when the Crown gave way, though retaining the "proemunientes" clause in the bishop's writ of summons.
