That the people have an original right to establish, for their future government, such principles as, in their opinion, shall most conduce to their own happiness, is the basis, on which the whole American fabric has been erected.... The principles, therefore, so established, are deemed fundamental. And as the authority, from which they proceed, is supreme ... they are designed to be permanent.... The powers of the legislature are defined, and limited; and that those limits may not be mistaken, or forgotten, the constitution is written.
John MarshallCertainly 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.
John MarshallNo principle of general law is more universally acknowledged, than the perfect equality of nations. Russia and Geneva have equal rights. It results from this equality, that no one can rightfully impose a rule on another....As no nation can prescribe a rule for others, none can make a law of nations.
John Marshall
