William Strong, Murray v. Charleston — Opinion of the Court
“ That cannot be, because if it could, the contract (in the language of Alexander Hamilton) would 'involve two contradictory things: an obligation to do, and a right not to do; an obligation to pay a certain sum, and a right to retain it in the shape of a tax. It is against the rules, both of law and of reason, to admit by implication in the construction of a contract a principle which goes in destruction of it.' The truth is, States and cities, when they borrow money and contract to repay it with interest, are not acting as sovereignties. They come down to the level of ordinary individuals. ”
