Uniform Act

In the United States, a Uniform Act is a proposed state law drafted by the Uniform Law Commission (ULC) and approved by its sponsor, the National Conference of Commissioners on Uniform State Laws (NCCUSL).

Federalism in the United States traditionally limits the legislative authority of the federal government in favor of the states. Specifically, the Tenth Amendment of the US Constitution states that "powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." Therefore, state governments are free to enact unique laws in any area beyond the purview of federal preemption. Under the doctrine of Erie Railroad Co. v. Tompkins (1938), federal courts cannot dictate law to states on pure issues of state common law (almost all of contract, tort, and family law). However, a variety of legal issues regularly transcend state lines, which makes a predictable and relatively uniform set of laws across states a desirable objective. "Uniform Acts" are collaboratively written model laws intended to facilitate the enactment of identical or similar laws by the separate states. Such laws are distinct from interstate compacts.

The NCCUSL is a body of private and government lawyers, state and federal judges, and law professors who are typically appointed by state governors. It drafts laws on a variety of subjects and proposes them for enactment by each state, the District of Columbia, the U.S. Virgin Islands, and Puerto Rico. NCCUSL was established in 1892. The NCCUSL, while influential, does not have any direct legislative power itself; uniform acts become laws only to the extent they are enacted into law by state legislatures.
