Ogden v. Saunders — Opinion of the Court
“ What is this 'obligation of contracts,' which is prohibited from being impaired by any act of State legislation? We answer, it is the civil obligation, the binding efficacy, the coercive power, the legal duty of performing the contract. The constitution meant to preserve the inviolability of contracts, as secured by those eternal principles of equity and justice which run throughout every civilized code, which form a part of the law of nature and nations, and by which human society, in all countries and all ages, has been regulated and upheld. ”
