California and 16 other states can sue the Trump administration for rolling back enforcement of the Endangered Species Act by allowing consideration of economic impacts, disregarding climate change and allegedly weakening protections for many imperiled creatures, a federal judge ruled Monday.

In denying administration officials’ request to dismiss the suit, U.S. District Judge Jon Tigar of Oakland said the states had shown they could suffer biological and economic harm if the law were weakened.

The Endangered Species Act, signed by President Richard Nixon in 1973, protects the existence and habitat of more than 1,600 plants and animals threatened with extinction. More than 300 of the species live in California’s lands and waters, including bighorn sheep, gray wolves, humpback whales and bald eagles.
