it with the respect due from one legislature, to laws passed by preceding legislatures. But the two cases are essentially different. A constitution, being derived from a superior authority, is to be expounded and obeyed, not controlled or varied by the subordinate authority of a legislature. A law, on the other hand, resting on no higher authority, than that possessed by every successive legislature; its expediency, as well as its meaning, is within the scope of the latter.
"The case in question has its true analogy, in the obligation arising from judicial expositions of the law on succeeding judges, the constitution being a law to the legislator, as the law is a rule of decision to the judge.
"And why are judicial precedents, when formed on due discussion and consideration, and deliberately sanctioned by reviews and repetitions, regarded as of binding influence, or rather of authoritative force, in settling the meaning of a law? It must be answered, 1st, because it is a reasonable and established axiom, and the good of society requires, that the rules of conduct of its members, should be certain and known, which would not be the case if any judge, disregarding the decisions of his predecessors, should vary the rule of law, according to his individual interpretation of it.—Misera est servitus ubi jus aut vagum aut incognitum. 2d, because an exposition of the law publicly made, and repeatedly confirmed by the constituted authority, carries with it, by fair inference, the sanction of those, who, having made the law through their legislative organ, appear under such circumstances, to have determined its meaning through their judiciary organ.
"Can it be of less consequence, that the meaning of a constitution should be fixed and known, than that the meaning of a law should be so? Can, indeed, a law be fixed in its meaning and operation, unless the constitution be so? On the contrary, if a particular legislature, differing in the construction of the constitution, from a series of preceding constructions, proceed to act on that difference, they not only introduce uncertainty and instability in the constitution, but in the laws themselves; inasmuch as all laws, preceding the new construction, and inconsistent with it, are not only annulled for the future, but virtually pronounced nullities from the beginning.
"But, it is said, that the legislator, having sworn to support the constitution, must support it in his own construction of it, however different from that put on by his predecessors, or whatever be the consequences of the construction. And is not the judge under the same oath to support the law? yet, has it ever been supposed, that he was required, or at liberty, to disregard all precedents, however solemnly repeated and regularly observed; and by giving effect to his own abstract and individual opinions, to disturb the established course of practice, in the business of the community? Has the wisest and most conscientious judge ever scrupled to acquiesce in decisions, in which he
