§103. Criteria for redistricting
This section establishes mandatory, ranked criteria for states' congressional redistricting plans, prohibiting use of any noncompliant plan. The criteria, in order of priority, are: (1) compliance with the U.S. Constitution, including equalizing total population; (2) compliance with the Voting Rights Act of 1965, including creation of districts enabling coalitions of two or more politically cohesive protected groups to elect representatives of choice; (3) preventing dilution of any Voting Rights Act-protected group's practical ability to nominate candidates and elect representatives of choice—assessed via factors including political cohesion, racially polarized voting, and crossover support—regardless of whether the group is a majority of the district's citizen voting age population; and (4) representing communities of interest (i.e., areas with shared ethnic, racial, economic, social, cultural, geographic, or historic identities, or socioeconomic conditions, including political subdivisions but excluding political parties or candidates) to the extent practicable, prioritizing those with greatest representational needs from inclusion in a single district.
This section further prohibits redistricting plans that, statewide, intentionally or effectively materially favor or disfavor a political party, as determined by the totality of circumstances including (A) computer modeling of electoral outcomes under past statewide federal general elections over the prior eight years, (B) statistical analysis of partisan advantage under foreseeable conditions, (C) comparisons to alternative compliant plans, and (D) process transparency and support. It creates a rebuttable presumption of violation in civil actions if a timely motion is filed within 30 days of plan enactment (or this Act's effective date, if later), with a hearing required within 15 days.
