Concurrent jurisdiction; provide for between federal and state governments over certain lands.

This bill modifies Mississippi law to clarify how federal and state governments share authority over certain lands, primarily affecting federal properties like military bases within Mississippi. It requires the federal government to provide written notice to the Mississippi Governor specifying the exact land boundaries, types of cases (including juvenile matters), and whether future land expansions are included. The Governor can then accept or reject this shared jurisdiction through an Executive Order, with agreements between state and federal agencies needing to be formalized via Memorandums of Understanding. The bill also updates existing law to confirm Mississippi state laws, including those for juveniles, remain fully applicable on these lands even when jurisdiction is shared.
