Even though the court struck down the voter rights act 2 months ago
No, it struck down the preclearance requirements in the VRA. Which means instead of the DOJ having to clear certain state's voting laws and the states suing if they feel that they should have been cleared, the DOJ now has to sue those states if they feel that those laws violate the VRA. Which is what they already did for the rest of the country.
Oops, they didn't strick down the whole thing, they struck down a part of it. My bad.
And the part that they didn't strike down has provisions for exactly this sort of suit when jurisdictions that aren't covered by preclearance do things that could be considered discriminatory. Those provisions didn't see much use, tho they did from time to time. Now that some Republicans in states formerly covered by preclearance have decided to go crazy with suppressing the voters they think won't vote for them, these sorts of suits are going to happen more often than they did.
All that the court decision changed was that the preclearance areas went from guilty until proven innocent to innocent until proven guilty. But that doesn't mean they can't be found guilty.
