In a 5–2 opinion, Chief Justice
Salmon P. Chase held that this use of
Congress's taxing power was authorized. Congress had just undertaken to provide for a uniform currency for the country. To protect the newly established national bank from undue competition for the state banks, Congress was using its power indirectly when it could have used a direct method. Congress had to protect the newly established
bank notes and restrain the notes of the state banks as money. Authority to do this arose from its power to regulate the circulation of coin. It cannot be doubted that under the Constitution the power to provide a circulation of coin is given to Congress. And it is settled by the uniform practice of the government and by repeated decisions, that Congress may constitutionally authorize the emission of bills of credit. ... Having thus, in the exercise of undisputed constitutional powers, undertaken to provide a currency for the whole country, it cannot be questioned that Congress may, constitutionally, secure the benefit of it to the people by appropriate legislation. To this end, Congress has denied the quality of legal tender to foreign coins, and has provided by law against the imposition of counterfeit and base coin on the community. To the same end, Congress may restrain, by suitable enactments, the circulation as money of any notes not issued under its own authority. Without this power, indeed, its attempts to secure a sound and uniform currency for the country must be futile. == References ==
