What it would have done

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

This bill requires sheriffs to request proof of legal presence status from individuals held in a county jail for an offense punishable as a felony. The bill also requires sheriffs to comply with detainers and administrative warrants received from the federal department of homeland security regarding individuals held in the county jail for a criminal offense.

Under the bill, sheriffs must annually certify to the Department of Revenue that they have complied with each of these requirements. If a sheriff fails to provide such a certification, DOR must reduce the county’s shared revenue payments for the next year by 15 percent. The bill also requires sheriffs to maintain a record of the number of individuals from whom proof of legal presence is requested who are verified as unlawfully present in this state and a list of the types of crimes for which those individuals were confined in the jail. The information must be provided to the Department of Justice upon request, and DOJ must compile the information and submit a report to the legislature.
