2000年8月，夏威夷最高法院关于27 mgd Waiahole沟渠农业灌溉系统命运的裁决根据夏威夷宪法、普通法和公共信托原则确立了用水优先权。最高法院确认了该州为该州人民保护水资源的公共信托责任，并因此承认三种受宪法保护的公共信托用水优于私人用水利益。他们还就国家应如何根据公共信托原则权衡相互竞争的用水提供了指导。本文揭示了夏威夷最高法院裁决的结果及其对夏威夷未来水资源规划的影响。包括7个参考文献、图表。

In August 2000, the Hawaii Supreme Court decision on the fate of the 27 mgd Waiahole Ditch agricultural irrigation system created a water use priority based on the Hawaii Constitution, Common Law and the Public Trust Doctrine. The Supreme Court affirmed the State's public trust responsibility to protect water resources for the people of the State and thus recognized three constitutionally protected public trust uses of water that are superior to private water interests. They also provided guidance on how the State should weigh competing water uses under the public trust doctrine. This paper discloses the findings of the Hawaii Supreme Court decision and the impacts to future water resource planning in Hawaii. Includes 7 references, figures.
