What law passed by congress in the first two decades of the nineteenth century upheld slavery?

The reason that the U.S. government began passing the anti-trust laws in the late nineteenth century are because of the following;

-          There is an emergence in separation of laws and policies

-          Financial concerns were evident in companies

-          Consolidation of giant systems due to small short line railroads.
