Article IV, Section 2 of the Constitution orders it. Presumably you are asking about the Fugitive Slave Act of 1850, which was a part of the Great Compromise of 1850. This law tried to more strongly enforce the Constitutional requirement to return runaway slaves; before 1850, many Northern states were passing laws that made it difficult to return slaves, such as by giving them the right to a trial. The Fugitive Slave Act set up special government commissioners who held considerable power to return slaves, and it overruled laws that would give slaves rights like the right to trial or even to testify in court. Police and other government officials who were caught not complying with the Act were automatically given very large fines and even prison sentences.

The fugitive slave act was written into law to round up runaway slaves that went up north where slavery was illegal. This act gave southerns the ability to demand their slaves back with help from the Federal government. it also made it illegal for "free people" to aide in the escape and quartering of runaway slaves.(I say free, not white because there were many free African Americans that helped runaway slaves, most notable Harriet Tubman and Fredrick Douglass) The fugitive slave act was actually quite popular in the south, especially with the plantation owners.
