""Whatever may be the force of the decision of the Supreme Court in binding the parties and settling their rights in the particular case before them, I am not prepared to admit that a construction given to the constitution by the Supreme Court in deciding any one or more cases fixes of itself irrevokably [sic] and permanently its construction in that particular and binds the states and the Legislative and executive branches of the General government, forever afterwards to conform to it and adopt it in every other case as the true reading of the instrument although all of them may unite in believing it erroneous."
I confess, I had to look it up, had no idea.
But won't spoil it for everybody else... it's well worth the effort.
