IT is probable, and almost certain, that in very early times, before our constitution arrived at it's full perfection, our kings in person often heard and determined causes between party and party. But at present, by the long and uniform usage of many ages, our kings have delegated their whole judicial power to the judges of their several courts; which are the grand depositary of the fundamental laws of the kingdom, and have gained a known and stated jurisdiction, regulated by certain and established rules, which the crown itself cannot now alter but by act of parliament[z]. And, in order to maintain both the dignity and independence of the judges in the superior courts, it is enacted by the statute 13 W. III. c. 2. that their commissions shall be made (not, as formerly, _durante bene placito_, but) _quamdiu bene se gesserint_, and their salaries ascertained and established; but that it may be lawful to remove them on the address of both houses of parliament. And now, by the noble improvements of that law in the statute of 1 Geo. III. c. 23. enacted at the earnest recommendation of the king himself from the throne, the judges are continued in their offices during their good behaviour, notwithstanding any demise of the crown (which was formerly held[a] immediately to vacate their seats) and their full salaries are absolutely secured to them during the continuance of their commissions: his majesty having been pleased to declare, that "he looked upon the independence and uprightness of the judges, as essential to the impartial administration of justice; as one of the best securities of the rights and liberties of his subjects; and as most conducive to the honour of the crown[b]."
