A federal judge is weighing whether to impose a preliminary injunction on a Northern California county facing a class action on claims it restricts water access for Asian Americans. Four Siskiyou County residents claim that a county ordinance is discriminatory against Asian Americans, who in some cases are forced to use bottled water. White residents don’t face the same discrimination. In one case, someone provided up to 4,000 gallons of water to another with no county intervention, said attorney John Do, who represents the plaintiffs, at a Friday hearing.
