Title 41 of the U.S. Code holds many of the key laws governing contracts with the federal government. A four-year effort to organize this collection of public contract laws and remove “ambiguities, contradictions, and other imperfections” was completed on January 4, 2011. The President’s signature on Public Law No. 111-350, 124 Stat. 367 (Jan. 4, 2011) [pdf] has the effect of renumbering the entirety of Title 41 and giving new section numbers to many of the most important government contract laws.
