The bill establishes a new legal framework allowing counties in Iowa to secede from the state through the adoption of an ordinance. Once an ordinance is enacted, the county will no longer be considered a political subdivision of Iowa, and its residents will be exempt from state laws and the state constitution. However, any property owned by the state of Iowa within the seceding county will remain under state ownership and control. Additionally, the ordinance must have an effective date of at least one year after its adoption.

Importantly, the bill stipulates that a county can only secede if it receives approval from the federal government and either another state to join it or the federal government to become an independent state or territory. This requirement ensures that the process of secession is regulated and contingent upon higher governmental authority.
