The California Supreme Court can protect incentives for responsible groundwater management by agreeing to review an appellate court decision (Mojave Pistachios v. Indian Wells Valley Groundwater Agency) challenging Indian Wells Valley Groundwater Sustainability Plan (“GSP”). The dispute is over whether the Sustainable Groundwater Management Act (“SGMA”) allows Indian Wells Valley to eviscerate a landowner’s (Mojave Pistachios LLC) groundwater rights without due process and impose unreasonable “fees” for a speculative GSP. The future of reasonable groundwater management hangs in the balance.
