Here’s the concluding section of Chief Justice Roberts’ majority opinion in the Voting Rights Act case:
Our decision in no way affects the permanent, nationwide ban on racial discrimination in voting found in §2. We issue no holding on §5 itself, only on the coverage formula. Congress may draft another formula based on current conditions. Such a formula is an initial prerequisite to a determination that exceptional conditions still exist justifying such an “extraordinary departure from the traditional course of relations between the States and the Federal Government.” … Our country has changed, and while any racial discrimination in voting is too much, Congress must ensure that the legislation it passes to remedy that problem speaks to current conditions.
