Environmental and animal advocacy groups haven’t shown they have legal standing to challenge the Trump administration’s revised Endangered Species Act regulations, but a lawsuit from a coalition of states can move forward, a federal court ruled Monday.

The U.S. District Court for the Northern District of California tossed a lawsuit from the Center for Biological Diversity, Defenders of Wildlife, and other groups, and a similar suit from the Animal Legal Defense Fund, but gave them 21 days to file an amended complaint with more information to support their claims that the regulations harm their members.
