Notwithstanding the fulness of this assent to so important a petition we find no vestige of either among the statutes, and the whole transaction is unnoticed by those historians who have not looked into our original records. If the compilers of the statute-roll were able to keep out of it the very provision that was intended to check their fraudulent machinations, it was in vain to hope for redress without altering the established practice in this respect; and indeed, where there was no design to falsify the roll it was impossible to draw up statutes which should be in truth the acts of the whole legislature, so long as the king continued to grant petitions in part, and to engraft new matter upon them. Such was still the case till the commons hit upon an effectual expedient for screening themselves against these encroachments, which has lasted without alteration to the present day. This was the introduction of complete statutes under the name of bills, instead of the old petitions; and these containing the royal assent and the whole form of a law, it became, though not quite immediately,[205] a constant principle that the king must admit or reject them without qualification. This alteration, which wrought an extraordinary effect on the character of our constitution, was gradually introduced in Henry VI.'s reign.[206] From the first years of Henry V., though not, I think, earlier, the commons began to concern themselves with the petitions of individuals to the lords or council. The nature of the jurisdiction exercised by the latter will be treated more fully hereafter; it is only necessary to mention in this place that many of the requests preferred to them were such as could not be granted without transcending the boundaries of law. A just inquietude as to the encroachments of the king's council had long been manifested by the commons; and finding remonstrances ineffectual, they took measures for preventing such usurpations of legislative power by introducing their own consent to private petitions. These were now presented by the hands of the commons, and in very many instances passed in the form of statutes with the express assent of all parts of the legislature. Such was the origin of private bills, which occupy the greater part of the rolls in Henry V. and VI.'s parliament. The commons once made an ineffectual endeavour to have their consent to all petitions presented to the council in parliament rendered necessary by law; if I rightly apprehend the meaning of the roll in this place, which seems obscure or corrupt.[207] [Sidenote: Interference of parliament with the royal expenditure.]
