What it's about

The Supreme Court struck down Section 4’s formula, so it can no longer be used to require those jurisdictions to get preapproval under Section 5.

Section 5 required jurisdictions selected by the Section 4(b) formula to get federal approval before changing voting rules.

Question presented

Does the renewal of Section 5 of the Voter Rights Act under the constraints of Section 4(b) exceed Congress' authority under the Fourteenth and Fifteenth Amendments, and therefore violate the Tenth Amendment and Article Four of the Constitution?

What the Court decided

Holding

Section 4 of the Voting Rights Act is unconstitutional; its formula can no longer be used as a basis for subjecting jurisdictions to preclearance. 679 F. 3d 848, reversed.

Result
Reversed

The Court's reasoning
