testify on their own behalf. Also, aiding a runaway slave by providing food or shelter was now a crime nationwide, punished by six months' imprisonment and a $1,000 fine. Officers capturing a fugitive slave were entitled to a fee for their work, and this expense was to be paid by the Federal Government. The law was so completely pro-slavery as to prohibit the admission of the testimony of a person accused of being an escaped slave into evidence at the judicial hearing to determine the status of the accused escaped slave. Thus, if free Blacks were claimed to be escaped slaves, they could not resist their return to slavery (or enslavement for the first time) by truthfully telling their actual history. Furthermore, the federal commissioners overseeing the hearings were paid $5 for ruling a person was free, but were paid $10 for determining they were a slave, thus providing a financial incentive to always rule in favor of slavery regardless of the evidence. The law further exacerbated the problem of free Blacks being kidnapped and sold as slaves. The Fugitive Slave Act was essential to meet Southern demands. In terms of public opinion in the North, the critical provision was that ordinary citizens were required to aid slave catchers, and made it a crime to assist a fugitive. Many Northerners deeply resented these requirements.The violent process of returning slaves to the South made the act controversial to Northerners. Resentment towards the Act further heightened tensions between the North and South, which were then inflamed further by abolitionists such as Harriet Beecher Stowe. Her novel, Uncle Tom's Cabin, stressed the horrors of recapturing escaped slaves and outraged Southerners.

Southerners in Congress, alarmed and outraged, were unanimous in opposing the provision, seen as a concession to the abolitionists and a bad precedent, but they were outvoted. However, Washington's residents could still easily buy and sell slaves in the nearby states of Virginia and Maryland. Implications Passage of the Compromise of 1850, as it came to be known, caused celebration in Washington and elsewhere, with crowds shouting, "The Union is saved!" Fillmore himself described the Compromise of 1850 as a "final settlement" of sectional issues, though the future of slavery in New Mexico and Utah remained
