'T]he causes and reasons which have produced this conflict between the general and state government should be made known, not only that the state may be justified to her sister states, who are equally interested in the preservation of the state rights ...
Resolved by the Senate and House of Representatives of the Commonwealth of Pennsylvania, &c. That, as a member of the Federal Union, the Legislature of Pennsylvania acknowledges the supremacy, and will cheerfully submit to the authority of the general government, as far as that authority is delegated by the constitution of the United States. ...
Resolved, That, should the independence of the states, as secured by the constitution, be destroyed, the liberties of the people in so extensive a country cannot long survive. To suffer the United States' courts to decide on STATE RIGHTS will, from a bias in favor of power, necessarily destroy the FEDERAL PART of our Government.'
