A federal appeals court declined to block Tennessee's congressional redistricting map that fractures a majority-Black district centered in Memphis, allowing the state to proceed with primary elections scheduled for August under the new boundaries.

The three-judge panel rejected a request for a preliminary injunction against the map Thursday. The decision clears the way for Tennessee to implement the redistricting plan immediately.

Voting rights advocates challenged the map as an unconstitutional racial gerrymander that dilutes Black voting power by splitting Memphis into multiple districts. The original Ninth Congressional District was a majority-Black seat where African American voters held decisive influence. The new configuration divides Memphis across multiple districts, dispersing Black voters among white-majority areas.

The panel's refusal to issue a preliminary injunction represents a procedural setback for the plaintiffs. Such injunctions are typically granted when challengers demonstrate a likelihood of success on the merits and risk of irreparable harm absent the order. The judges did not rule on the underlying constitutional question but determined that blocking the map ahead of primaries was not warranted at this stage of litigation.

Tennessee Republicans redrew congressional lines after the 2020 census, citing traditional redistricting principles. The state maintains the map complies with the Voting Rights Act and constitutional requirements. Democrats and civil rights organizations argue the reconfiguration deliberately targets the state's largest Black-majority district to reduce Democratic representation.

This redistricting dispute reflects broader national fights over voting maps following the 2020 census. Courts have split on whether breaking up majority-minority districts constitutes illegal racial gerrymandering or permitted partisan redistricting. The Supreme Court's decision in Shelby County v. Holder weakened federal oversight of voting changes, shifting enforcement authority to federal district courts.

The case will likely proceed through the courts, but Tennessee now enters its August primary with the new map in effect. Any ultimate ruling requiring
