Plaintiffs' Map Submission
On October 6, 2025, as part of the ongoing remedial process in this case, Plaintiffs filed two map submissions with the Court. These maps were submitted because the map enacted by the Legislature on October 6, 2025, fails to abide by and conform to Proposition 4’s requirements.
Plaintiffs' Map 1 comes from a set of 10,000 maps generated by a computer algorithm designed to comply with Proposition 4’s priority-ordered redistricting criteria without considering partisan data. Map 1 splits only one municipality and has a significant population overlap with the Commission's Orange and Purple Maps (84.6% and 80.6%, respectively).
Plaintiffs' Map 2 is a "least change" map based on the Legislature's adopted map with changes made to correct its failures to conform to Proposition 4's requirements. In particular, it corrects the enacted map’s failure to minimize municipal and county splits to the greatest extent practicable and the enacted map’s failure to comply with Proposition 4’s prohibition on party favoritism. Map 2 splits only one municipality and has an average of 84.1% population overlap with the Legislature’s enacted map. Map 2 also has substantial population overlap with the Commission’s Purple (82.0%) and Orange (77.8%) maps.

On October 17, 2025, Plaintiffs will submit briefs and expert reports in support of these map submissions, and the Court will hold an evidentiary hearing on October 23 and 24, 2025. The final map will be in place by November 10, 2025.
