M'CULLOCH
v. MARYLAND, 17 U.S. 316
(1819)
MARSHALL,
Ch. J., delivered the opinion of the court.
qIn the case now to be determined, the defendant, a sovereign state,
denies the obligation of a law enacted by the legislature of the Union
[creating a national bank], and the plaintiff, on his part, contests the
validity of an act which has been passed by the legislature of that state [to
tax a branch of the national bank in the state].
