Senate Bill 581 Summary

• Establishes mandatory criteria for redrawing congressional and state legislative districts following the 2020 census, prioritizing equal population, contiguity, county groupings, and compact districts.

• Sets strict population deviation standards: congressional districts must have zero or one person deviation from ideal population; state legislative districts must not exceed 10% total deviation or 5% deviation from ideal.

• Prohibits partisan gerrymandering by requiring third-party analysis of at least 20,000 alternative district plans and limiting partisan advantage to one additional congressional district, two state senate districts, or three state house districts beyond the most common seat distribution.

• Restricts use of election data to ensemble analysis only and requires disclosure of all consultants, communications, and external district plans within 24 hours, making such information public records.

• Dissolves attorney-client privilege and confidentiality protections regarding redistricting once the district plan becomes law.
