A recent Supreme Court ruling that weakened federal voting rights protections has triggered a new wave of redistricting efforts across multiple states, with Georgia becoming the first to act on redrawing legislative districts since the decision.

The 6-3 Supreme Court ruling in late April struck down a majority-Black congressional district in Louisiana as an illegal racial gerrymander, providing legal grounds for states to reshape districts with large minority populations. The decision has already prompted Georgia's Republican-led Legislature to schedule a special session for June 17 to redraw voting districts for the 2028 elections, including state House and Senate seats and potentially the state's utility regulatory commission.

Georgia's redistricting effort stems from a 2023 federal court ruling that found some of the state's congressional and legislative districts were drawn in a racially discriminatory manner. The Legislature had previously approved revised maps with new majority-Black districts, though these resulted in little change to Republican majorities in the 2024 elections. The upcoming special session could allow Republicans to undo those court-ordered changes in light of the Supreme Court's recent decision.

The Supreme Court's Louisiana ruling has already affected pending cases in multiple states. A federal appeals court is allowing Alabama to use a state Senate map approved by Republican lawmakers instead of one imposed by a federal judge, affecting two districts in the Montgomery area. The court has also sent legislative redistricting cases involving Black voters in Mississippi and Native Americans in North Dakota back to lower courts for reconsideration.

Analysts expect the decision's impact to extend beyond state legislatures to local governments. Over the past four decades, cities, counties and school boards have been involved in more than three-fifths of the 466 lawsuits alleging violations of Section 2 of the Voting Rights Act. The Supreme Court decision has already affected some local cases, with plaintiffs voluntarily dismissing a challenge in Meriwether County, Georgia, and courts accepting new legal briefs in Mississippi cases.

While about half of all states have constitutional provisions prohibiting mid-decade redistricting of state legislative seats, legal experts note that lawmakers may have fewer incentives to redraw their own districts compared to congressional maps, since most state legislative chambers are already dominated by one party with comfortable margins.
