During the reign of Edward I (1272-1307) the role of parliament became more important as, "(D)iscontent with royal government prompted demands for a larger voice in advising the king, amounting at times to a claim to control his choice of advisors; in extreme cases to share his executive power."(40) By 1327 parliaments were accepted as part of the normal practice and both Edward I and II used them as an administrative tool. However, much parliamentary business was judicial, and the power of parliament to limit the role of the monarchy was to come much later.
