Justice Samuel Alito's majority opinion in Louisiana v. Callais cited faulty data claiming Black voter turnout now exceeds white voter turnout, according to The Guardian's analysis of Justice Department filings used in the ruling. The Supreme Court decision, issued in late April 2026, significantly weakened Section 2 of the Voting Rights Act and eliminated majority-Black congressional districts in Louisiana with implications for representation nationwide. Multiple sources confirm the underlying turnout data was methodologically flawed, though experts debate whether the error was the primary driver of the outcome or a supporting argument in a predetermined ideological direction.
