The laws of Congress are restricted to a certain sphere, and when they depart from this sphere, they are no longer supreme or binding.

As to Taxes, they are evidently inseparable from Government. It is impossible without them to pay the debts of the nation, to protect it from foreign danger, or to secure individuals from lawless violence and rapine.

The states have authority to interpret the Constitution, enforce it, and protect the people from violations of it by the federal government In the first place, there is not a syllable in the plan under consideration which directly empowers the national courts to construe the laws according to the spirit of the Constitution, or which gives them any greater latitude in this respect than may be claimed by the courts of every State.

The complete independence of the courts of justice is peculiarly essential in a limited Constitution. By a limited Constitution, I understand one which contains certain specified exceptions to the legislative authority. Limitations of this kind can be preserved in practice no other way than through the medium of courts of justice, whose duty it must be to declare all acts contrary to the manifest tenor of the Constitution void. Without this, all the reservations of particular rights or privileges would amount to nothing.

The circumstances that endanger the safety of nations are infinite, and for this reason no constitutional shackles can wisely be imposed on the power to which the care of it is committed.

The propriety of a law, in a constitutional light, must always be determined by the nature of the powers upon which it is founded.

A struggle for liberty is in itself respectable and glorious. . . . When conducted with magnanimity, justice and humanity, it ought to command the admiration of every friend to human nature. But if sullied by crimes and extravagancies, it loses its respectability.
