The trial court erred in denying plaintiff-water district's application for a preliminary injunction because Water Code section 60339 authorizes the trial court to grant an injunction against an operator of a water-producing facility from producing groundwater if it is delinquent in the payment of an assessment, and under the doctrine of "pay first, litigate later," defendant-city must pay the assessment until there is a final judgment in its separate Proposition 218 Lawsuit, which is litigating the validity of the assessment.
