If the title in the code is a positive law title, the law itself is one federal statute that has been enacted by Congress. A positive law title reorganizes the law in a more efficient way; any unclear provisions or errors are clarified or removed, meaning the final law title provides the most modern and clear interpretation of the law. This makes positive law titles legal evidence of the law and are considered more reliable by U.S. courts. 14 titles of the U.S. Code are positive law titles.
