Native American tribes in North Dakota challenged a state legislative map they said dilutes their voting power. An appeals court said they can't sue.

Supreme Court Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented Thursday from the court’s decision to halt an outlier federal appeals court ruling that would have further limited the Voting Rights Act.

An appeals court ruling that said private parties cannot file VRA lawsuits goes against settled law, attorneys said.
