McDonald, J.delivering the opinion.
This is an action of trover, instituted for the recovery ot certain California State bonds and ■ deeds conveying land* which were sent by Harden’s Express from San Francisco* *706in the State of California, to Columbus in this State over the-usual mail route. They were transmitted by express without the authority of the defendant in error, who is the owner, and she refuses to pay the amount charged for their transportation, and the plaintiff in error refusing to deliver them without, this suit was brought for their recovery. The defendant in error insists, that the contract for their transportation, is an infraction of the postal laws óf the United States, and that no freight or other charge can he demanded of her, and' that the defendant in the Court below has no lien upon them for such freight or charge. If the bonds and deeds are mailable matter, and the Express Company is prohibited by law from transporting such mailable matter, then the contract,, beingin contravention of public law, is void, and the defendant-can claim no right of any sort under it. The 9th section of the Act of Congress of the 3d March, 1845, declares it to be unlawful for any person or persons to establish any private Express or Expresses for the conveyance, or in any manner to canse to be conveyed, or to provide for the conveyance or transportation by regular trips or at stated periods or intervals from one city, town or other place, to any other city„, town, or place in the United States, between and from and to which cities, towns, or other places the United States mail* is regularly transported under theauthority of the Post Office Department, of any letters or packets or packages of letters or other matter properly transmiftible in the United States mail,, except newspapers, phamplets, magazines, and periodicals. A penalty of one hundred and fifty dollars is inflicted by tho-Act for its violation. Brightly's Dig. 767.
The same Act declares what shall be matter properly transmittible by mail. All letters and newspapers, all magazines and phamplets periodically published, in regular series, or in successive numbers under the same title &c., and all other written or printed matter, whereof each copy or numbershall !iot exceed eight ounces in weight, except bank notes sent in packages or bundles unaccompanied by written letters, ar& *707declared to be such matter. Any packet or packets, of whatever size or weight, being made up of any such mailable matter, shall subject all persons concerned in transporting them to all the penalties of the Act, equally as if it or they were cot so made up into a packet or packages, lb. 768 and 769. By the same Act, books, magazines or pamphlets, or newspapers, not marked, directed, or intended for immediate distribution to subscribers, or others, but intended for sale as merchandize, and transported in the usual mode of transporting merchandize over the particular route used, and sent or consigned to some bona fide dealer or agent for the sale thereof are not within the prohibition. Books bound or unbound not weighing over four pounds are to be deemed mailable matter. Ib. 786. Were these bonds and deeds mailable matter? They were either written or printed matter, and each one does not exceed eight ounces in weight. It follows that they are mailable matter. If each bond or deed is under eight ounces in weight, the transportation of a packet of whatever size or weight, is prohibited under a penalty, and Is unlawful.
The Act of Congress prohibits the establishment of a private Express for any such purpose and prohibits it3 under a penalty.
The business is unlawful, and contracts made with the persons who, in defiance of the law, carry it on, and in furtherance of that business, are unlawful and void. The object of the Government was to prevent effectually, all arrangements and practices by which the revenue of the Post ©dice Department might be cut off or impaired. The Acts of Congress are plain and intelligible and it would be well for those who incautiously violate them to look to it.
It is argued, that if the contract falls within the prohibition and is therefore void, that still the defendant is a common carrier and of course, has a lien in that character until «barges are paid, and that his possession was legally acquired. If it be true that the possession was legally acquired, it *708is a possession for the true owner, and if he hold against the owner after a demand, it is a denial of the owner’s right and a conversion. What right has he against the rightful owner, if he acquired that possession from a person who had neither power nor authority to deliver the possession? None at all. The rightful owner has a right to claim her property whenever she finds it, and because the person who has it is a common carrier, he cannot demand of her the discharge of a lien, which did not originate in any contract with her express or implied for the transportation. Suppose she did not desire the property sent?
But the contract for the transportation was illegal and void whether express or implied and in whatever form presented. It is equally a fraud on the postal laws, whether the packet was transported for one dollar or for five hundred, or if it was wholly gatuitous. No lien can attach in such ease.
Judgment affirmed.
