Nathan Clifford, Mount Pleasant v. Beckwith — Opinion of the Court
“ Neither argument nor authority is necessary to prove that a State legislature cannot pass a valid law impairing the obligations of a contract, as that general proposition is universally admitted. Contracts under the Constitution are as sacred as the Constitution that protects them from infraction, and yet the defence in this case, if sustained, will establish the proposition that the effect of State legislation may by such as to deprive a party of all means of sustaining an action of any kind for their enforcement. ”
