If the authorities of South Carolina had not obstructed the legitimate action of the courts of the United States, or if they had permitted the State tribunals to administer the law according to their oath under the Constitution and the regulations of the laws of the Union, the General Government might have been content to look to them for maintaining the custody and to encounter the other inconveniences arising out of the recent proceedings. Even in that case, however, the process of replevin from the courts of the State would be irregular and unauthorized. It has been decided by the Supreme Court of the United States that the courts of the United States have exclusive jurisdiction of all seizures made on land or water for a breach of the laws of the United States, and any intervention of a State authority which, by taking the thing seized out of the hands of the United States officer, might obstruct the exercise of this jurisdiction is unlawful; that in such case the court of the United States having cognizance of the seizure may enforce a redelivery of the thing by attachment or other summary process; that the question under such a seizure whether a forfeiture has been actually incurred belongs exclusively to the courts of the United States, and it depends on the final decree whether the seizure is to be deemed rightful or tortuous; and that not until the seizure be finally judged wrongful and without probable cause by the courts of the United States can the party proceed at common law for damages in the State courts. But by making it "unlawful for any of the constituted authorities, whether of the United States or of the State, to enforce the laws for the payment of duties, and declaring that all judicial proceedings which shall be hereafter had in affirmance of the contracts made with purpose to secure the duties imposed by the said acts are and shall be held utterly null and void," she has in effect abrogated the judicial tribunals within her limits in this respect, has virtually denied the United States access to the courts established by their own laws, and declared it unlawful for the judges to discharge those duties which they are sworn to perform. In lieu of these she has substituted those State tribunals already adverted to, the judges whereof are not merely forbidden to allow an appeal or permit a copy of their record, but are previously sworn to disregard the laws of the Union and enforce those only of South Carolina, and thus deprived of the function essential to the judicial character of inquiring into the validity of the law and the right of the matter, become merely ministerial instruments in aid of the concerted obstruction of the laws of the Union.
