Virginia Democrats scored a victory Monday at the Supreme Court in a case about racial gerrymandering in the state. The court's ruling was largely procedural, but the practical upshot is to leave in place a legislative map that's relatively favorable to Democrats. It replaced a map that was thrown out for discriminating against black voters.

Why it matters: The court is set to rule later this month on a question it has never answered: Whether gerrymandering for purely partisan purposes can ever go too far. Monday's ruling doesn't have any direct implications for those cases, but Democrats are happy for any victory, however small, in any gerrymandering suit.

New Zealand authorities laid safety violation charges Monday against 10 organizations and three individuals over the fatal Whakaari/White Island volcanic disaster last December, per a statement from the agency WorksSafe.

Details: WorksSafe declined to name those charged as they may seek name suppression in court. But Prime Minister Jacinda Ardern said government agencies GNS Science, which monitors volcanic activity, and the National Emergency Management Agency were among those charged over the "horrific tragedy" that killed 22 people.
