Before we leave this subject it will be proper to take notice of a remarkable stretch of prerogative, which, if drawn into precedent, would have effectually subverted this principle of parliamentary consent in legislation. In the 15th of Edward III. petitions were presented of a bolder and more innovating cast than was acceptable to the court:--That no peer should be put to answer for any trespass except before his peers; that commissioners should be assigned to examine the accounts of such as had received public moneys; that the judges and ministers should be sworn to observe the Great Charter and other laws; and that they should be appointed in parliament. The last of these was probably the most obnoxious; but the king, unwilling to defer a supply which was granted merely upon condition that these petitions should prevail, suffered them to pass into a statute with an alteration which did not take off much from their efficacy--namely, that these officers should indeed be appointed by the king with the advice of his council, but should surrender their charges at the next parliament, and be there responsible to any who should have cause of complaint against them. The chancellor, treasurer, and judges entered their protestation that they had not assented to the said statutes, nor could they observe them, in case they should prove contrary to the laws and customs of the kingdom, which they were sworn to maintain.[121] This is the first instance of a protest on the roll of parliament against the passing of an act. Nevertheless they were compelled to swear on the cross of Canterbury to its observance.[122]
