If then the Courts of justice are to be considered as the bulwarks of a limited Constitution, against Legislative encroachments, this consideration will afford a strong argument for the permanent tenure of Judicial offices, since nothing will contribute so much as this to that independent spirit in the Judges, which must be essential to the faithful performance of so arduous a duty. This independence of the Judges is equally requisite to guard the Constitution and the rights of individuals, from the effects of those ill humors, which the arts of designing men, or the influence of particular conjunctures, sometimes disseminate among the People themselves, and which, though they speedily give place to better information, and more deliberate reflection, have a tendency, in the mean time, to occasion dangerous innovations in the Government, and serious oppressions of the minor party in the community.
Alexander Hamilton
