Until the People have, by some solemn and authoritative act, annulled or changed the established form, it is binding upon themselves collectively, as well as individually; and no presumption, or even knowledge of their sentiments, can warrant their Representatives in a departure from it, prior to such an act. But it is easy to see, that it would require an uncommon portion of fortitude in the Judges to do their duty as faithful guardians of the Constitution, where Legislative invasions of it had been instigated by the major voice of the community. But it is not with a view to infractions of the Constitution only, that the independence of the Judges may be an essential safeguard against the effects of occasional ill humors in the society. These sometimes extend no farther than to the injury of the private rights of particular classes of citizens, by unjust and partial laws. Here also the firmness of the Judicial magistracy is of vast importance in mitigating the severity, and confining the operation of such laws. It not only serves to moderate the immediate mischiefs of those which may have been passed, but it operates as a check upon the Legislative body in passing them; who, perceiving that obstacles to the success of iniquitous intention are to be expected from the scruples of the Courts, are in a manner compelled, by the very motives of the injustice they meditate, to qualify their attempts.
Alexander Hamilton
