Concurrent legislative jurisdiction refers to the legislative jurisdiction held by the U.S. concurrently with a state. The state grants to the U.S., and reserves to itself, the right to exercise the same legislative authority.
The following is a state law that provides a statutory framework regarding Concurrent legislative jurisdiction :
Concurrent legislative jurisdiction for purposes of criminal law enforcement means the joint power of the U.S. and the Commonwealth of Kentucky to enact and enforce their own criminal laws, including those pertaining to motor vehicle traffic control, over the lands in question. Under concurrent legislative jurisdiction for purposes of criminal law enforcement, both the U. S. and the Commonwealth of Kentucky, or either of them, may take jurisdiction over a given criminal offense, according to the laws of the respective sovereign. [KRS § 3.255].
