The result of the frequent transgressions of the Fugitive Slave Law on the one hand and of the clamorous demand for a measure adequate to the needs of the South on the other, was the passage of a new Fugitive Recovery Bill in 1850.[42] The increased rigor of the provisions of this act was ill adapted to generate the respect that a good law secures, and, indeed, must have in order to be enforced. The law contained features sufficiently objectionable to make many converts to the cause of the abolitionists; and a systematic evasion of the law was regarded as an imperative duty by thousands. The Fugitive Slave Act of 1850 was based on the earlier law, but was fitted out with a number of clauses, dictated by a self-interest on the part of the South that ignored the rights of every party save those of the master. Under the regulations of the act the certificate authorizing the arrest and removal of a fugitive slave was to be granted to the claimant by the United States commissioner, the courts, or the judge of the proper circuit, district, or county. If the arrest were made without process, the claimant was to take the fugitive forthwith before the commissioner or other official, and there the case was to be determined in a summary manner. The refusal of a United States marshal or his deputies to execute a commissioner's certificate, properly directed, involved a fine of one thousand dollars; and failure to prevent the escape of the negro after arrest, made the marshal liable, on his official bond, for the value of the slave. When necessary to insure a faithful observance of the fugitive slave clause in the Constitution, the commissioners, or persons appointed by them, had the authority to summon the posse comitatus of the county, and "all good citizens" were "commanded to aid and assist in the prompt and efficient execution" of the law. The testimony of the alleged fugitive could not be received in evidence. Ownership was determined by the simple affidavit of the person claiming the slave; and when determined it was shielded by the certificate of the commissioner from "all molestation ... by any process issued by any court, judge, magistrate, or other person whomsoever." Any act meant to obstruct the claimant in his arrest of the fugitive, or any attempt to rescue, harbor, or conceal the fugitive, laid the person interfering liable "to a fine not exceeding one thousand dollars, and imprisonment not exceeding six months," also liable for "civil damages to the party injured in the sum of one thousand dollars for each fugitive so lost." In all cases where the proceedings took place before a commissioner he was "entitled to a fee of ten dollars in full for his services," provided that a warrant for the fugitive's arrest was issued; if, however, the fugitive was discharged, the commissioner was entitled to five dollars only.[43] [42] Appendix A, pp. 361-366.
