It seems scarcely necessary to say that the "full force and credit " clause has reference only to civil judgments. No State, it has been held, is by this provision compelled to lend its aid in the enforcement of the penal laws of another. This was definitely determined in Wisconsin v. Pelican Insurance Company.7 In this case original suit had been brought in the Supreme Curt of the United States by the State of Wisconsin upon a judgment obtained in its own courts against an insurance company, a Louisiana corporation, for penalties imposed by a statute of Wisconsin for not making returns to the insurance commissioners of the State. The federal court held that the grant to it of original jurisdiction in suits between a State and citizens of another State, though given in general terms, was not to be construed to extend to actions brought by a State, to enforce even indirectly in another jurisdiction a provision of its own penal law. The court say: "The grant is of 'judicial power,' and was not intended to confer upon the courts of the United States jurisdiction of a suit or prosecution by the one State, of such a nature that it could not, on the settled principles of public and international law, be entertained by the judiciary of the other State at all. . . . The rules that the courts of no country execute the penal laws of another applies not only to prosecutions and sentences for crimes and misdemeanors, but to all suits in favor of the State for the recovery of pecuniary penalties for any violation of statutes for the protection of its revenue, or other municipal laws, and to all judgments for such penalties. If this were not so, all that would be necessary to give ubiquitous effect to a penal law would be to put the claim for a penalty into the shape of a judgment."
