Case Notes


Although the public trust doctrine and the state water code share similar core principles, the code does not supplant the protections of the public trust doctrine. 94 H. 97, 9 P.3d 409.

Despite evidence that permit applicant violated chapter 340E, neither the water code nor the public trust precluded the commission on water resource management from allocating water to applicant to supply water to domestic end users from a delivery system that may not comply with chapter 340E; as this jurisdiction separately regulates water allocation and drinking water standards, and there was no discernable legislative intent to make water use permit applications subject to compliance with chapter 340E, violations of chapter 340E were not germane to a review of the propriety of water allocation under the water code and the public trust. 116 H. 481, 174 P.3d 320.
