Nevada Attorney General Adam Laxalt led a ten state coalition of attorneys general, in filing a friend-of-the-court brief in the U.S. Supreme Court defending the ability of state governments to regulate groundwater usage. The brief urges the Court to review a recent Ninth Circuit decision that concluded that the federal government has broadly reserved rights to groundwater that preempt long-established state-law regulations. Laxalt says by filing this brief, his office encourages the Supreme Court to take the necessary steps to clarify the States’ groundwater rights and to ensure Nevada’s best interests are being protected from unnecessary and unwarranted federal interference.
