In the next case, the object may be to expel the bank from the state; but how is this object to be ascertained, or who is to judge of the motives of legislative acts?

Certainly all those who have framed written constitutions contemplate them as forming the fundamental and paramount law of the nation, and consequently the theory of every such government must be, that an act of the legislature, repugnant to the constitution, is void.
