John McLean, Massingill v. Downs — Opinion of the Court
“ If, therefore, a State law should enact that a judgment should be no evidence of debt, or should abolish all writs of execution, such a law would not be applicable to the proceedings of the federal courts, because, in the first instance, it would take away the proper intrinsic effect of the judgment itself, and make it, in whole or in part, no judgment; and, in the other instance, it would take from the United States courts a necessary part of the organization of a court, namely, the power to carry into effect its own judgments. ”
