An act of parliament, thus made, is the exercise of the highest authority that this kingdom acknowleges upon earth. It hath power to bind every subject in the land, and the dominions thereunto belonging; nay, even the king himself, if particularly named therein. And it cannot be altered, amended, dispensed with, suspended, or repealed, but in the same forms and by the same authority of parliament: for it is a maxim in law, that it requires the same strength to dissolve, as to create an obligation. It is true it was formerly held, that the king might in many cases dispense with penal statutes[p]: but now by statute 1 W. & M. st. 2. c. 2. it is declared, that the suspending or dispensing with laws by regal authority, without consent of parliament, is illegal.

VII. There remains only, in the seventh and last place, to add a word or two concerning the manner in which parliaments may be adjourned, prorogued, or dissolved.
An adjournment is no more than a continuance of the session from one day to another, as the word itself signifies: and this is done by the authority of each house separately every day; and sometimes for a fortnight or a month together, as at Christmas or Easter, or upon other particular occasions. But the adjournment of one house is no adjournment of the other[q]. It hath also been usual, when his majesty hath signified his pleasure that both or either of the houses should adjourn themselves to a certain day, to obey the king's pleasure so signified, and to adjourn accordingly[r]. Otherwise, besides the indecorum of a refusal, a prorogation would assuredly follow; which would often be very inconvenient to both public and private business. For prorogation puts an end to the session; and then such bills, as are only begun and not perfected, must be resumed de novo (if at all) in a subsequent session: whereas, after an adjournment, all things continue in the same state as at the time of the adjournment made, and may be proceeded on without any fresh commencement.

A prorogation is the continuance of the parliament from one session to another, as an adjournment is a continuation of the session from day to day. This is done by the royal authority, expressed either by the lord chancellor in his majesty's presence, or by commission from the crown, or frequently by proclamation. Both houses are necessarily prorogued at the same time; it not being a prorogation of the house of lords, or commons, but of the parliament. The session is never understood to be at an end, until a prorogation: though, unless some act be passed or some judgment given in parliament, it is in truth no session at all[]. And formerly the usage was, for the king to give the royal assent to all such bills as he approved, at the end of every session, and then to prorogue the parliament; though sometimes only for a day or two[t]: after which all business then depending in the houses was to be begun again. Which custom obtained so strongly, that it once became a question[], whether giving the royal assent to a single bill did not of course put an end to the session. And, though it was then resolved in the negative, yet the notion was so deeply rooted, that the statute 1 Car. I. c. 7. was passed to declare, that the king's assent to that and some other acts should not put an end to the session; and, even so late as the restoration of Charles II, we find a proviso tacked to the first bill then enacted[w] that his majesty's assent thereto should not determine the session of parliament. But it now seems to be allowed, that a prorogation must be expressly made, in order to determine the session. And, if at the time of an actual rebellion, or imminent danger of invasion, the parliament shall be separated by adjournment or prorogation, the king is empowered[x] to call them together by proclamation, with fourteen days notice of the time appointed for their reassembling.
