Today, as John Miller and Yuval Levin remind us, is the sesquicentenary of Abraham Lincoln’s inauguration.  Here is our greatest president’s mature understanding of the constitutional role of the Supreme Court–and the limits on that role–from his First Inaugural Address on March 4, 1861:

I do not forget the position assumed by some, that constitutional questions are to be decided by the Supreme Court; nor do I deny that such decisions must be binding in any case, upon the parties to a suit, as to the object of that suit, while they are also entitled to very high respect and consideration, in all parallel cases, by all other departments of the government. And while it is obviously possible that such decision may be erroneous in any given case, still the evil effect following it, being limited to that particular case, with the chance that it may be over-ruled, and never become a precedent for other cases, can better be borne than could the evils of a different practice. At the same time the candid citizen must confess that if the policy of the government, upon vital questions, affecting the whole people, is to be irrevocably fixed by decisions of the Supreme Court, the instant they are made, in ordinary litigation between parties, in personal actions, the people will have ceased, to be their own rulers, having, to that extent, practically resigned their government, into the hands of that eminent tribunal. Nor is there, in this view, any assault upon the court, or the judges. It is a duty, from which they may not shrink, to decide cases properly brought before them; and it is no fault of theirs, if others seek to turn their decisions to political purposes.
