米連邦最高裁は先週、「ルイジアナ州対カレイス事件」において、投票権法の重要な要素を解体する判決を下した。この決定により、複数の州で迅速な選挙区再編の動きが引き起こされている。また、原告側代表に関する新たな事実も浮上した。
この判決は、ルイジアナ州の選挙区割りおよび投票権法第2条に関するものである。これにより、同州におけるマイノリティの有権者の票の希薄化に対する保護が事実上終了した。テネシー州の当局は木曜日、これに応じる形で州内で唯一の黒人多数派選挙区を3つに分割した。これにより、人口の63％を黒人が占めるメンフィスの投票権が希薄化されることとなる。

Callais that Louisiana’s congressional map (SB8) was an unconstitutional racial gerrymander, concluding the Voting Rights Act did not require the state to draw an additional majority-Black district. Sen. Raphael Warnock, D-Ga., called the ruling “a massive and devastating blow,” warning it could accelerate redistricting fights across Southern states ahead of the 2026 midterm elections.
