The demand from the South for more effective Federal legislation led to the second fugitive slave law, drafted by Senator
James Murray Mason of
Virginia, grandson of
George Mason, and enacted on September 18, 1850, as a part of the
Compromise of 1850. Special commissioners were to have
concurrent jurisdiction with the U.S. circuit and district courts and the inferior courts of territories in enforcing the law; fugitives could not testify in their own behalf; no trial by jury was provided. The person claiming to be the slaves' owner could determine whether the slave was believable, and most times they were sent back to slavery. Penalties were imposed upon marshals who refused to enforce the law or from whom a fugitive should escape, and upon individuals who aided black people to escape; the marshal might raise a
posse comitatus; a fee of $10 (equivalent to $ in ) was paid to the commissioner when his decision favored the claimant, only $5 (equivalent to $ in ) when it favored the fugitive. The supposed justification for the disparity in compensation was that, if the decision were in favor of the claimant, additional effort on the part of the commissioner would be required in order to fill out the paperwork actually remanding the slave back to the South. Both the fact of the escape and the identity of the fugitive were determined on purely
ex parte testimony. If a slave was brought in and returned to the master, the person who brought in the slave would receive the sum of $10 (equivalent to $ in ) per slave. The severity of this measure led to gross abuses and defeated its purpose; the number of
abolitionists increased, the operations of the Underground Railroad became more efficient, and new
personal liberty laws were enacted in Vermont (1850), Connecticut (1854), Rhode Island (1854), Massachusetts (1855),
Michigan (1855),
Maine (1855 and 1857),
Kansas (1858) and
Wisconsin (1858). The personal liberty laws forbade justices and judges to take cognizance of claims, extended
habeas corpus and the privilege of jury trial to fugitives, and punished false testimony severely. In 1854, the Supreme Court of Wisconsin went so far as to declare the Fugitive Slave Act unconstitutional. These state laws were one of the grievances that South Carolina would later use to justify its secession from the Union. Attempts to carry into effect the law of 1850 aroused much bitterness. The arrests of
Thomas Sims and of
Shadrach Minkins in Boston in 1851; of
Jerry M. Henry, in
Syracuse, New York, in the same year; of
Anthony Burns in 1854, in Boston; and of the
Garner family in 1856, in
Cincinnati, with other cases arising under the Fugitive Slave Law of 1850, probably had as much to do with bringing on the
Civil War as did the controversy over slavery in the Territories. ==Civil War-era legal status of fugitive slaves==
