Ensuring the Public Trust

Brian Gray | July 1st, 2012


The California Supreme Court’s recognition of the public trust doctrine as an integral part of California’s water rights system was one of the momentous events in the history of California (if not United States) environmental policy.’ The court looked back to the foundational purposes of the public trust to hold that there are limits to the sovereign power to privatize the rights to use the waters of the state, and it looked forward to conclude that prudent development and sustainable use of California’s water resources require the state to retain authority to protect the public trust for the benefit of all Californians. The court also defined the public trust as an environmental baseline that both protects the traditional interests of navigation, commerce, and fisheries and embodies the contemporary scientific and popular understanding that there are ecological limits to the diversion and use of water for consumptive purposes. The lessons of National Audubon Society v. Superior Court2 are now a commonplace of water rights law, appearing not just in administrative orders and judicial opinions, but also in standard water rights terms, policy studies, and legislation.
