History and Evolution of the Public Trust Doctrine in the USA
The public trust doctrine originated in Roman law in the 6th century and was later incorporated into English law in the 13th century as part of the Magna Carta. Originally, it was understood that certain common properties, such as the seashore, highways, and running water, were dedicated to the public because the interests and activities that these properties facilitated, such as the right to navigable waters and fishing, should be protected for all to enjoy. These resources were owned by no one and the public had undefined rights of use and enjoyment.
This doctrine was adopted by US law and continued the notion that certain public uses of natural resources ought to be specially protected. The US Supreme Court decision in Illinois Central Railroad Co. v. Illinois is the foundational case for the public trust doctrine in the USA and lays out a “traditional scope” for the doctrine, which has been built upon by various jurisdictions in the United States. The Court held in a 4:3 decision that the State of Illinois did not have the authority to grant fee title to submerged lands because it was held in the public trust as navigable waters. This case sets out the traditional scope of the public trust doctrine, which has been subsequently modified by different states throughout the decades.
Illinois Central Railroad Co. v. Illinois, 146 U.S. 387 (1892)

Court(s):
• Supreme Court of the United States
Plaintiffs:
• Illinois Central Railroad Company
Defendants:
• State of Illinois
Facts:
• In 1869, the Illinois state legislature passed legislation giving the Illinois Central Railroad Company title (i.e. ownership) to more than 1000 acres of submerged land in the Chicago harbour that extended one mile from the shoreline into Lake Michigan.
• The grant was later revoked by state legislature but the Company continued to build tracks, piers, and other facilities along the lake front.
• The Illinois Attorney General filed a suit against the Company in order to stop the construction.
Judgements and Reasons:
• The Supreme Court of the United States confirmed that the public trust doctrine applies to the lands under the navigable waters of Lake Michigan and the Great Lakes; therefore, the submerged land in the Chicago harbour was held in trust for the public and could not be given away.
• The Court permitted the Illinois state legislature to revoke its grant of the commercial waterfront and set aside the Company’s title to the land.
• The Court held that state legislatures lack the authority to grant title to lands under navigable waters with two exceptions – for grants not impairing the public interest and grants that actually improved the public trust.
The traditional scope of the public trust doctrine articulated in Illinois Central Railroad sets out two well-defined sets of resources:
- Navigable waters, the land submerged thereunder, and the resources located therein; and
- Tidal waters, the lands submerged thereunder, and the resources located therein.
This traditional scope has since been modified and expanded or restricted in different states.
How the Scope of the Public Trust Doctrine Has Changed
There is no single, “definite scope” of the modern public trust doctrine in the United States. That is, the scope of the doctrine has been defined differently in different states and for federal lands. The reason for this is because the public trust doctrine is widely understood to be a matter of state law and each state’s Supreme Court is the final interpreter of its own laws. The United States Supreme Court is limited to deciding matters of federal law. As a result, in some states, the public trust doctrine has expanded greatly from the “traditional scope” defined in Illinois Central Railroad and its applicability has been broadened; examples include California and New Jersey. In other states, such as Ohio, the traditional scope has not been expanded on as much.
Below are some examples of how legal cases in different states have expanded or restricted the use of the public trust doctrine:
State of Massachusetts
Gould v. Greylock Reservation Commission, 350 Mass. 410 (1966)
This case is significant because it established that the public trust doctrine applies not just to shorelines and navigable waters, but also to the use of lands.

Court(s):
- Supreme Judicial Court of Massachusetts
Plaintiffs:
- Five citizens of Berkshire County, Massachusetts
Defendants:
- Greylock Reservation Commission and the Mount Greylock Tramway Authority
Facts:
- In the late 19th century, the State of Massachusetts acquired about 9000 acres of natural forest on Mount Greylock in Berkshire County to create a public park and enacted a statute creating the Greylock Reservation Commission to manage the park.
- In 1953, the state legislature created the Mount Greylock Tramway Authority to build an aerial tramway on Mount Greylock.
- The Authority also started plans to build a ski resort on Mount Greylock in partnership with a private corporation.
- Five citizens of Berkshire County brought an action to stop the development of the tramway and the ski resort. The citizens brought the suit as beneficiaries of the public trust under which the park land was said to be held.
Judgement and Reasons[1]:
- The Court held that the Commission acted in excess of its statutory grant of authority when it leased land in the park to the Authority and that the Authority acted in excess of its statutory grant of authority when it entered into an agreement with the private corporation.
- The Court questioned why the State should subordinate a public park, serving a useful purpose as undeveloped land, to the demands of private investors to build a commercial facility for profit; thus implying use of the public trust doctrine.
- The Court grounded its decision on the presumption that the state does not ordinarily intend to divert trust properties in a manner that lessens public uses and that any legislation that intends to change the uses of public lands must clearly state this intention.
- This case is significant because it shows the evolution of the public trust doctrine beyond application to shorelines and navigable waters to include the use of lands.
State of New Jersey
Borough of Neptune City v. Borough of Avon-by-the-Sea, 61 N.J. 296 (1972)
This case first expanded the uses of tidelands protected by the public trust beyond the traditional scope of navigation and fishing to include recreational uses such as bathing, swimming, and other shore activities.

Court(s):
- Superior Court of New Jersey
Plaintiffs:
- Borough of Neptune City and two of its residents
Defendants:
- Borough of Avon-by-the-Sea
Facts:
- In the 1950’s, with the advent of the automobile traffic, beachfront municipalities in the state of New Jersey began taking steps to limit congestion by regulating the use of beach facilities and by charging fees.
- Non-residents of Avon-by-the-Sea, such as those from Neptune City, were charged higher fees than residents of Avon-by-the-Sea for beach access.
- The Plaintiffs asked the Court whether or not a municipality could charge non-residents higher fees than residents for beach access.
Judgement and Reasons:
- The Supreme Court of New Jersey held that, while municipalities may charge reasonable fees for the use of their beaches, they may not discriminate between residents and non-residents and set aside the fee scheme.
- The Court expanded the traditional scope of the public trust doctrine from navigation and fishing to include recreational uses such as bathing, swimming, and other shore activities and, therefore, New Jerseys’ beach and ocean waters must be open to all people on equal terms and without preference.
State of California
National Audubon Society v. Superior Court, 33 Cal. 3d 419 (1983)
This case is significant for several reasons, such as for applying the public trust doctrine to flowing water, but above all, because the Court found that the state has a duty to protect the public trust whenever feasible and to ensure that the taking and appropriating of water is continually supervised for responsible use.

Court(s):
- Supreme Court of California
Plaintiffs:
- National Audubon Society
Defendants:
- Department of Water and Power of the City of Los Angeles
Facts:
- Mono Lake, the second largest lake in California, supports large numbers of nesting and migratory birds and is fed by water flowing from five different streams.
- The Department of Water and Power in Los Angeles diverted water from four of the streams to feed the city of Los Angeles.
- The diversions caused the level of Mono Lake to drop dramatically and damaged the scenic and ecological value of the lake.
- The Plaintiff, a wildlife conservation society, filed a suit to prohibit the diversions on the theory that the lake is protected by a public trust.
Judgement and Reasons:
- The Supreme Court of California held that the public trust doctrine applies to flowing waters and water rights, just as it does to tide and submerged lands and beds of inland navigable waters.
- The Court also held that the public trust prevents any party from acquiring a vested right to appropriate water in a manner harmful to the interests protected by the public trust.
- This case is significant because it placed a duty on the state to protect the public trust and to ensure that the taking and appropriating of water is continually supervised for responsible use.
As a result of these and other cases, in some US jurisdictions, the public trust doctrine protection now extends to wilderness preserves, state parks, water for recreational purposes, water rights, beaches, and wildlife.
However, in some US jurisdictions, the public trust doctrine has also been curtailed. In Merrill v. Ohio, Department of Natural Resources (2009), the Ohio Court of Appeals held the public trust only extended from the water to the natural shoreline which, compared to Borough of Neptune City, is a much narrower interpretation of the public trust doctrine.
Application of the Public Trust Doctrine to Climate Change
As climate change awareness has increased over recent decades, more parties have brought arguments to US courts that the public trust doctrine imposes an obligation on governments to protect natural resources, such as the atmosphere, from the impacts of climate change.
Below are some recent cases demonstrating how different states have applied the public trust doctrine to climate change.
State of Oregon
Chernaik v. Brown, 367 Ore. 143 (2020)
This case is significant because the Court rejected the notion that the atmosphere constitutes a public trust resource and found that the public trust doctrine does not impose specific obligations on the state to protect resources from climate change impacts.
Click here to learn more
Court(s):
- Supreme Court of Oregon
Plaintiffs:
- Two Oregon youth: Olivia Chernaik and Kelsey Cascadia Rose Juliana
Defendants:
- Governor of the State of Oregon, Kate Brown
Facts:
- Two Oregon youth filed a lawsuit against Governor Kate Brown and the State of Oregon.
- The Plaintiffs asked the Court to order the State to prepare an annual accounting of Oregon’s carbon dioxide (CO2) emissions and to create a viable climate recovery plan for reducing CO2 emissions in order to protect Oregon’s natural resources.
- The Plaintiffs claimed that the State had a fiduciary duty, which it breached, to prevent substantial impairment of those resources caused by emissions of greenhouse gases.
- The Plaintiffs also argued for the expansion of the public trust doctrine to encompass more natural resources, including the atmosphere, and suggested the following test to identify what resources are covered by the doctrine:
- Is the resource not easily held or improved; and
- Is the resource of great value to the public for uses such as commerce, navigation, hunting, and fishing?
Judgement and Reasons:
- The Supreme Court of Oregon rejected the Plaintiffs’ claims.
- The Court acknowledged that the public trust doctrine in Oregon currently encompasses navigable waters and the submerged and submersible lands underlying those waters.
- Although the Court noted that public trust is capable of expanding to include more natural resources (as has occurred in other states), it decided not to expand the doctrine to encompass other natural resources in Oregon, such as the atmosphere, at this time.
- The Court found that the Plaintiffs’ suggested test was too broad and would fail to provide “practical limitations”, making it difficult to conceive of a natural resource that would not satisfy the test.
- The Court also rejected the claim that the State had a fiduciary duty to protect natural resources from climate change impacts because importing private trust principles (such as obligations that trustees of private trusts owe to beneficiaries) to the public trust doctrine could result in a fundamental restructuring of the public trust doctrine and impose new and unnecessary obligations on the State.
Juliana v. United States, 947 F.3d 1159 (9th Cir., 2020)
This case is significant because it utilizes the public trust doctrine for the issue of climate change. While the US District Court for the District of Oregon was willing to accept that the global climate could constitute a public trust, the Ninth Circuit Court reversed this finding and dismissed the case because Article III courts, such as the District Court, do not have the power to order, design, supervise, or implement a remedial plan to reduce CO2 emissions.

Court(s)
- 2015 filing in US District Court for the District of Oregon; appealed in 2020 to the US Court of Appeals for the Ninth Circuit; motions ongoing in 2021 at the Ninth Circuit Court
Plaintiffs:
- 21 youth between ages eight to nineteen, Earth Guardians (an environmental NGO), and Dr. James Hansen (a climate scientist)
Defendants:
- United States, President Obama, and numerous executive agencies
Facts:
- The Plaintiffs claimed that the Defendants have known for more than fifty years that carbon dioxide (CO2) produced by burning fossil fuels was destabilizing the climate system in a way that would significantly endanger the Plaintiffs, with damage persisting for millennia.
- The Plaintiffs seek:
- A declaration that their constitutional and public trust rights have been violated; and
- An order preventing the Defendants from violating those rights and directing the Defendants to develop a plan to reduce CO2
Judgement and Reasons:
- The District Court for the District of Oregon applied the public trust doctrine to climate change, finding that the Plaintiffs had a right to public trust claims grounded in the Fifth and Ninth Amendments to the US Constitution.
- The Court denied the government’s motion to dismiss the application of the public trust doctrine, concluding that the Plaintiffs had a due process right to a “climate system capable of sustaining human life.”
- The Court did not explicitly state that the public trust doctrine could be broadened to apply to the atmosphere and to climate change, but the Court held that the government’s public trust duties, when combined with the Environmental Protection Agency’s duty to protect the public health from airborne pollutants, meant that the Plaintiff’s arguments had some merit. As a result, the Court held that the government’s motion to dismiss the application of the public trust doctrine should be denied until there was further development of the evidentiary record.
- However, the US government appealed the decision to the US Court of Appeals for the Ninth Circuit, which rejected the Plaintiffs’ claim for a lack of Article III standing.
- Article III courts are federal courts created under Article III of the US Constitution and include the US Supreme Court and the lower courts of the United States established by Congress.
- The Ninth Circuit rejected the Plaintiffs’ claims based on the fact that the specific relief they seek is not within the power of an Article III court to grant.
- The Ninth Circuit held that it is beyond the judicial power of an Article III court to order, design, supervise, or implement the Plaintiffs’ remedial plan to reduce CO2
- The Court further stated: “[t]hat the other branches [of the US government] may have abdicated their responsibility to remediate the problem does not confer on Article III courts, no matter how well-intentioned, the ability to step into their shoes.”
- The Court held that the Plaintiffs’ complaints should be made to the political branches or to the electorate at large, rather than to the courts.
- The Ninth Circuit did not expand or discuss the public trust doctrine in depth due to having established that the Plaintiffs’ claims lack Article III standing.
State of Florida
Reynolds v. Florida, 139 S.Ct. 27 (Fla. Cir. Ct., 2018)
Similar to the decision in Juliana, the Florida Circuit Court held that it is not appropriate for a court to provide relief for issues regarding damage to the atmosphere as a result of climate change from greenhouse gases.

Court(s):
- Florida Circuit Court
Plaintiffs:
- Eight Florida youth between ages eight and 19
Defendants:
- State of Florida
Facts:
- The Plaintiffs alleged that Florida state officials and agencies violated their fundamental rights under Florida common law and the Florida State Constitution of life, liberty and property, and the pursuit of happiness, which includes a stable climate system.
- The Plaintiffs argued that the State had a legal obligation to protect Florida’s public trust resources, including the atmosphere, from climate change and had contributed to climate change by the creation and operation of a fossil fuel-based energy system.
Judgements and Reasons:
- The Court dismissed the claim, holding that it was not appropriate for a court to provide relief for “inherently political questions” that must be resolved by the political branches of the government.
State of Hawaii
In re The Gas Co. dba Hawai’i Gas, 147 Haw. 186 (2020)
This case is significant because the Supreme Court of Hawaii held that the State of Hawai’i has a continuing duty to uphold its public trust obligations and monitor the use of trust property even if the use of the public trust resources has not changed.
Click here to learn more
Court(s):
- Supreme Court of Hawai’i
Plaintiffs:
- Two not-for-profit groups, Life of the Land (LOL) and Hui Aloha Aina o Ka Lei Maile Ali’I (KLM)
Defendants:
- Public Utilities Commission of Hawai’i
Facts:
- LOL and KLM challenged whether the Public Utilities Commission of Hawai’i (PUC) fulfilled its statutory and constitutional obligations in reviewing an application by Hawaii Gas to increase the price of natural gas in order cover the costs of two new liquefied natural gas projects.
- LOL and KLM argued that the PUC failed to fulfill its obligations under Hawaii’s State Constitution as a public trustee to conserve and protect the state’s natural resources.
Judgement and Reasons:
- The Court confirmed that a decision to increase the price of natural gas triggers a state agency’s public trust obligations, even where there is no change in the use of the public trust resource.
- The Court found that the State has a continuing duty to monitor the use of the trust resources, even if the use of the resources has not changed.
- Unfortunately, the Court found that the record was not sufficiently developed for it to address the issue of the public trust.
- The Court sent the decision back to the PUC for further proceedings and ordered the PUC to consider its constitutional obligations in re-deciding the issue.
State of Alaska
Sinnok v. Alaska, ELR 20188 (Alaska Super. Ct , 2018)
In this case, the Supreme Court of Alaska, much like the decision in Juliana, held that a climate plan to stabilize the climate and protect public trust resources are policy and science based, and thus not within the power of the courts.
Click here to learn more
Court(s):
- Supreme Court of Alaska
Plaintiffs:
- A group of Alaskan youth between ages five to 20
Defendants:
- State of Alaska
Facts:
- The Plaintiffs filed a complaint against the State of Alaska alleging that the State has contributed to climate change through its actions regarding fossil fuels and carbon emissions
- The Plaintiffs sought:
- An order that the State conduct an accounting of carbon emissions and create a climate recovery plan in order to stabilize the climate system and protect vital public trust resources; and
- A declaration that the State’s actions have violated their fundamental rights to a stable climate system.
Judgement and Reasons:
- The Court dismissed the Plaintiffs’ claims.
- The Court held that the Plaintiffs’ claims were science and policy based, which are “better reserved for executive branch agencies or the legislature,” otherwise, granting their claims would violate the separation of powers between the courts and the government.
- The Court also held that a declaratory judgement would not have any practical effect because it would not impact greenhouse gas emissions in Alaska or protect the Plaintiffs from climate-related harms.
State of Pennsylvania
Funk v. Wolf, 144 A.3d 228 (2016)
In this case, the Pennsylvania Commonwealth Court found that if there are no laws that mandate the State to take action to address climate change, then the Plaintiffs will not have any right to request such actions.
Click here to learn more
Court(s):
- Pennsylvania Commonwealth Court
Plaintiffs:
- Five children and a young adult
Defendants:
- Governor of Pennsylvania, Tom Wolf; Pennsylvania Public Utility Commission; and other officials in the State’s executive branch
Facts:
- The Plaintiffs assert that their rights granted by the Pennsylvania Constitution to natural resources such as clean air, pure water, and to the preservation of natural, scenic, historic and esthetic values of the environment have been infringed.
- Plaintiffs sought to compel the Pennsylvania Public Utility Commission (PUC) and the Governor to develop and implement a comprehensive plan to regulate greenhouse gases, including studies to determine how to protect their rights from climate change.
- The Plaintiffs also asked for a declaration from the Court that
- the right to a safe levels of greenhouse gases in the atmosphere is protected by the Constitution and that the State must protect (and not infringe) that right; and
- the State failed to meet that obligation.
Judgement and Reasons:
- The Court found that the Plaintiffs had failed to point to any legislative enactments or regulatory provisions that mandated the PUC and Governor to implement any regulations to address climate change.
- Therefore, the Plaintiffs had no clear right to have the PUC and Governor conduct the requested studies and requested regulations.
- The Court also dismissed their claim for declaratory relief because doing so would have no practical effect.
In summary, as of now, most jurisdictions in the US have been reluctant to expand the public trust doctrine to include the atmosphere and address the climate crisis. The courts have dismissed attempts to use the public trust doctrine to impose specific obligations on governments to reduce greenhouse gases and protect natural resources from climate change impacts. Generally, the courts have reasoned that they do not have the power to order, design, supervise, or implement remedial plans to reduce greenhouse gas emissions. They note that, since these issues are based in science and policy, they should be reserved for the executive and legislative branches of the government.
However, there is still the possibility that this may change. In the dissenting opinion in the Juliana case, Judge Staton held that the Plaintiffs’ claims were to enforce the most basic structural principle embedded in the US system of liberty: “that the Constitution does not condone the Nation’s willful destruction.” Judge Staton stated that even though granting the Plaintiffs’ claims alone will not halt climate change, that “does not mean that … [the suit] presents no claim suitable for judicial resolution.” Additionally, the Plaintiffs are planning to take their case to the US Supreme Court, thus there is still the possibility that the US Supreme Court will reverse the lower court’s decisions.
Similarly, in Chernaik, the majority held that even though they had to reject the Plaintiffs’ claims, it does not end the possibility that the public trust doctrine could be expanded in the future to include imposing additional duties to the state. In the dissenting opinion, Chief Justice Walters, stated that instead of in the future, “the time is now” for the court to declare that the state has a fiduciary duty to protect natural resources under the public trust doctrine.
It remains to be seen how the public trust doctrine will evolve and be used in the future of the United States. As of now, use of the public trust doctrine to impose obligations to protect resources from climate change have been unsuccessful.
