Supreme Court sends closely watched Native American voting rights decision back to lower court

The Supreme Court acted in a Voting Rights Act case brought by Native American tribes on Monday, saying a closely watched ruling needs to be reconsidered after the high court weakened the Civil Rights-era law.

The justices ordered lower courts to take another look at the decision that went against the tribes and undercut a key enforcement mechanism: lawsuits from voters and advocacy groups.

Advocacy groups are key players because they bring most of the lawsuits filed under the provision of the Voting Rights Act known as Section 2.
