Framework for Legal Personhood and Ecological Justice

Section One: Introduction

1.1 Research Background and Significance

Water is essential to life. Yet in the eyes of the law, it remains largely unprotected—leaving many communities without access to safe drinking water. This paradox lies at the heart of a growing global movement to transform the legal status of the natural world. For centuries, Western legal systems have treated water and other natural entities as property—resources to be owned, extracted, and exploited. This anthropocentric framework has enabled the degradation of freshwater ecosystems at an accelerating rate, with freshwater species populations declining by eighty-three percent since 1970 and nearly one-third of the world's wetlands lost.

The practical significance of reimagining water's legal status cannot be overstated. Rivers, lakes, and wetlands sustain every aspect of life, from the water we drink to the climate we depend on. Yet environmental collapse and humanitarian suffering are always interdependent: every degraded river translates into unsafe drinking water, failed crops, displacement, and deepening inequality. For communities worldwide—particularly Indigenous peoples who have maintained sacred relationships with water for millennia—the failure of legal systems to protect water represents a crisis of both ecology and justice.

Theoretically, Kelsey Leonard's work fills a critical gap in the discourse on environmental law and Indigenous rights. As a water scientist, legal scholar, policy expert, and enrolled citizen of the Shinnecock Nation, Leonard bridges Indigenous legal traditions and Western jurisprudence in ways that challenge the foundational assumptions of both. Her framework supplements existing environmental law scholarship by demonstrating that legal personhood for water is not merely a theoretical innovation but a practical mechanism rooted in Indigenous worldviews—worldviews that recognize water not as a resource to be managed but as a relative to be honored. By seeking to establish Indigenous traditions of water conservation as the foundation for international water policy-making, Leonard addresses a fundamental knowledge gap: how can legal systems be transformed to reflect the inherent rights of the natural world?

1.2 Core Concept Definitions

Legal personhood, as defined within Leonard's framework, is the legal recognition of an entity—whether a corporation, a river, or a lake—as having rights and duties under the law. Granting legal personhood to water means that lakes and rivers receive the same legal rights as humans. This is not anthropomorphism but a practical legal mechanism that enables water bodies to be represented in court, to have standing to sue, and to be protected as rights-bearing entities.

Water as a relative is a core Indigenous concept that Leonard foregrounds: "Water is more than a resource; it's a relative". This framing shifts the relationship from one of ownership and extraction to one of kinship and responsibility. Leonard has stated that she belongs to the waters of Shinnecock Bay, and in calling herself Shinnecock—"people of the Stony Shore"—she inherits "a duty, a responsibility, an ethic of care".

Rights of Nature is the global legal and philosophical framework that encompasses the recognition of the legal personhood of natural elements. Once regarded as an unthinkable cause, it has now become a meaningful reference in environmental politics and an emergent movement in defense of Mother Earth.

Water Back is an emerging concept to which Leonard has contributed, meaning "the return of Water and kin to Indigenous Peoples" and "the restoration of humanity's responsibility to care for Water and the recognition of Indigenous Peoples' inherent relationships, connections, rights and responsibilities to Water".

1.3 Current Research Status, Domestic and International

The field of Rights of Nature has evolved significantly over the past two decades. The constitutionalization of rights of nature in Bolivia and Ecuador, along with the recognition of the rights of rivers in New Zealand and Canada and of a lake in India, are exemplary cases that have attracted the attention of legal scholars both in the Global North and South.

Several distinct approaches have emerged. The constitutional model, exemplified by Ecuador and Bolivia, embeds rights of nature in national constitutions, granting nature the right to exist, persist, maintain, and regenerate its vital cycles. The legislative model, seen in New Zealand's Te Awa Tupua (Whanganui River) Act, grants legal personhood to specific rivers through national legislation. The Indigenous-led model, reflected in the recognition of the Muteshekau-shipu (Magpie River) by both the Innu of Ekuanitshit and the Minganie Regional County Municipality, demonstrates how Indigenous legal traditions can work in partnership with settler legal systems. The local governance model, as seen in municipalities that have passed ordinances granting rights to rivers, lakes, and watersheds, often pioneered through the work of organizations like the Community Environmental Legal Defense Fund. Most recently, a water body in Spain, the Mar Menor lagoon, was granted rights, becoming the first natural entity to be granted legal personhood in a European context.

Despite this progress, significant shortcomings persist. Many rights of nature laws remain underenforced or unimplemented. Critics question whether legal personhood translates into meaningful ecological protection on the ground. There is ongoing debate about whether rights of nature frameworks offer substantive legal and political tools for addressing environmental crises or whether they risk being co-opted by dominant legal and economic systems.

Leonard's work addresses these gaps by grounding the rights of water in Indigenous legal traditions and by advocating for the incorporation of tribal law into existing legal systems. Her framework moves beyond abstract legal theory to articulate a practical vision: "We can create laws through which we grant legal personhood to water. We can start to honor the original treaties between Indigenous peoples and non-Indigenous peoples for water protection".

1.4 Framework and Core Objectives

This article follows a theory-oriented structure, examining Leonard's framework for water personhood as a foundational approach to reimagining the legal relationship between humanity and the natural world. The core question it seeks to answer is: What are the principles, precedents, and practical mechanisms that enable lakes and rivers to be recognized as rights-bearing entities, and how can this framework transform our relationship with water?

The article is organized into four main sections. Following this introduction, Section Two presents the theoretical framework, tracing the origin and evolution of legal personhood for water, explicating its core principles and global precedents, and discussing its conditions and limitations. Section Three addresses practical applications, common misconceptions, and key insights for readers. Section Four summarizes core conclusions and offers an outlook on future developments.

Readers should come away with a clear understanding of legal personhood for water as both a legal mechanism and a philosophical reorientation—one that challenges anthropocentric assumptions and offers a pathway toward ecological justice.

Section Two: Main Body — Foundational Theory / System of Principles

2A.1 Origin and Evolution of the Theory

The intellectual origins of legal personhood for nature can be traced to Christopher Stone's seminal 1972 article, "Should Trees Have Standing?"—a work that argued for granting legal rights to natural objects. Yet the deeper roots of this framework lie in Indigenous legal traditions that have long recognized the inherent rights of the natural world.

Leonard's own journey reflects this convergence of Indigenous knowledge and Western legal scholarship. As a water scientist and legal scholar with degrees from Harvard University, the University of Oxford, Duquesne University, and McMaster University, she bridges multiple knowledge systems. Her work is grounded in her identity as an enrolled citizen of the Shinnecock Nation and her understanding that "I belong to the waters of Shinnecock Bay".

A pivotal moment in the evolution of this framework came in 2017 when New Zealand granted legal personhood to the Whanganui River—the first river in the world to receive such recognition. This landmark decision was the result of decades of advocacy by the Whanganui iwi (tribe), who had fought for recognition of their ancestral relationship with the river. The Te Awa Tupua Act established the river as a legal entity with its own rights and appointed guardians to represent its interests.

This precedent has inspired a cascade of similar recognitions worldwide. In Colombia, the Río Atrato was granted legal personhood in 2016. In India, the Ganga and Yamuna rivers were declared legal persons in 2017, though this ruling was later challenged. In Canada, the Muteshekau-shipu (Magpie River) received recognition of its legal personhood and inherent rights from both the Innu of Ekuanitshit and the Minganie Regional County Municipality in 2021. In the United States, municipalities and Native American tribes have enacted local rights of nature laws. And in 2022, Spain's Mar Menor lagoon became the first natural entity in Europe to be granted legal personhood.

Leonard's TED Talk, delivered at TEDWomen 2019, has been viewed over three and a half million times, making her one of the most prominent voices advocating for water personhood. Her scholarship explores legal personhood for water and seeks to establish Indigenous traditions of water conservation as the foundation for international water policy-making.

2A.2 Core Assumptions and Fundamental Viewpoints

Leonard's framework rests on several foundational assumptions about law, ecology, and justice.

First, the current legal framework is fundamentally inadequate. In the eyes of the law, water remains largely unprotected, leaving many communities without access to safe drinking water. This inadequacy is not a bug but a feature of a legal system that treats nature as property rather than as a rights-bearing entity.

Second, legal personhood is a practical tool, not a philosophical abstraction. Granting lakes and rivers legal personhood affords specific rights and protections: it grants water the right to exist, the right to be free from pollution, and the right to sustain life. These are not symbolic gestures but enforceable legal protections.

Third, Indigenous legal traditions offer a foundation for transformation. Leonard seeks to establish Indigenous traditions of water conservation as the foundation for international water policy-making. This is not about importing romanticized notions of Indigenous culture but about recognizing that Indigenous peoples have maintained working legal systems for water protection for millennia.

Fourth, legal change enables relational change. Granting legal personhood to water is "the first step to protecting our bodies of water and fundamentally transforming how we value this vital resource". Legal recognition creates the conditions for a deeper shift in human relationships with the natural world.

Fifth, ecological justice and Indigenous self-determination are inseparable. Leonard's scholarship explores legal personhood for water in the context of the United Nations Declaration on the Rights of Indigenous Peoples and the defining international legal principle of self-determination. Water justice cannot be achieved without Indigenous sovereignty.

2A.3 Essential Components and Framework Model

Leonard's framework consists of several interconnected components that together constitute a comprehensive approach to water personhood.

Component One: Legal Personhood as Rights-Bearing Status

The core legal mechanism is the recognition of water bodies as legal persons—entities capable of bearing rights and duties. This means that rivers, lakes, and other water bodies are no longer treated as property but as rights-bearing entities with the right to exist, flourish, regenerate, and evolve. As Leonard states, granting legal personhood to water "affords the following rights and protections. It grants water the right to exist".

Component Two: Guardianship and Representation

Legal personhood requires mechanisms for representation. When a river is recognized as a legal person, guardians are appointed to represent its interests. These guardians—often Indigenous peoples and local communities—speak on behalf of the river in legal proceedings and ensure that its rights are protected. This creates a formal voice for nature in governance systems that have historically excluded it.

Component Three: Indigenous Legal Traditions

Leonard's framework centers Indigenous legal traditions as the foundation for water personhood. This is not merely about consulting Indigenous communities but about recognizing that Indigenous legal systems have long recognized the inherent rights of water. The concept of "Water Back"—the return of Water and kin to Indigenous Peoples and the restoration of humanity's responsibility to care for Water—captures this relational orientation.

Component Four: International Law and Transnational Movement

The rights of nature movement has become a global phenomenon, with legal innovations spreading across continents. As scholars have noted, rights of nature is "a legal concept from the Global South that is inspiring the Global North rather than vice versa, which makes it a reverse legal transplant". Leonard's work contributes to this transnational discourse by demonstrating how Indigenous legal traditions can inform international water policy-making.

Component Five: Transformative Valuation

The ultimate goal of legal personhood is not merely legal protection but a fundamental transformation in how we value water. When water is recognized as a relative rather than a resource, the relationship shifts from extraction to care, from ownership to kinship.

2A.4 Classification and Branches of the Theory

Leonard's framework can be understood through several analytical lenses that situate it within broader traditions of legal and philosophical thought.

The Indigenous Jurisprudence Tradition: Leonard's work is grounded in Indigenous legal traditions that recognize the inherent rights of the natural world. This tradition challenges the anthropocentrism of Western law and offers alternative frameworks for human-nature relationships.

The Earth Law Tradition: The rights of nature movement is part of a broader Earth Law approach that seeks to recognize the legal rights of ecosystems. This tradition draws on ecological science, Indigenous knowledge, and legal innovation to create new frameworks for environmental protection.

The Legal Pluralism Tradition: The recognition of water personhood across multiple legal systems—Indigenous, national, and international—exemplifies legal pluralism. Leonard's work demonstrates how different legal traditions can interact and cross-fertilize.

The Environmental Justice Tradition: Water personhood is fundamentally a justice issue. Communities without access to safe drinking water, Indigenous peoples fighting for recognition of their water rights, and ecosystems facing degradation all demand legal recognition and protection.

The Decolonial Tradition: By centering Indigenous legal traditions and challenging the supremacy of Western law, Leonard's framework participates in a broader project of decolonizing law and knowledge.

2A.5 Applicable Conditions and Limitations

Leonard's framework is applicable across contexts where water bodies face degradation and where legal systems have failed to provide adequate protection. It is particularly relevant in jurisdictions with Indigenous legal traditions, in countries where rights of nature laws have been enacted, and in international water governance.

However, several significant limitations must be acknowledged. First, implementation remains a challenge. While legal personhood has been granted to numerous water bodies, enforcement has often been inconsistent. Scholars have raised questions about whether these legal innovations actually impact ecological protection on the ground.

Second, there is a risk of co-optation. Rights of nature frameworks risk being co-opted by dominant legal and economic systems that may undermine their transformative potential. Legal personhood can become a symbolic gesture that fails to constrain extractive activities.

Third, the framework requires political will and institutional capacity. Granting legal personhood to water requires legislative action, judicial interpretation, and governance mechanisms that may not exist in all contexts.

Fourth, there are tensions between Indigenous and Western legal systems. While Leonard advocates for incorporating tribal law into existing law, this process is not without challenges. Different legal traditions have different ontologies, epistemologies, and procedures that must be navigated with care.

Fifth, the framework does not address all dimensions of water justice. Legal personhood addresses the legal status of water but does not automatically resolve issues of water access, distribution, or quality. It is part of a broader solution, not the whole solution.

Section Three: Application and Implications

3.1 Practical Application Scenarios

For Legal Practitioners and Policymakers: Leonard's framework offers a blueprint for legislative and judicial action. Policymakers can introduce legislation granting legal personhood to specific water bodies, as has been done in New Zealand, Colombia, India, Canada, and Spain. Legal practitioners can bring cases arguing for the recognition of water rights and can represent water bodies as legal persons in court proceedings.

For Indigenous Communities: Leonard's work provides a framework for asserting Indigenous legal traditions and water rights. Indigenous nations can advocate for the recognition of their inherent relationships with water and can participate in governance structures as guardians of water bodies. As Leonard demonstrates, "We can start to honor the original treaties between Indigenous peoples and non-Indigenous peoples for water protection".

For Environmental Advocates and Organizations: The rights of nature movement offers a powerful tool for environmental advocacy. Communities confronting specific ecological crises—pipelines, polluting refineries, extraction permits—have used rights of nature frameworks as tools of local resistance and defense. Municipalities have passed ordinances granting rights to rivers, lakes, and watersheds.

For Educators and Communicators: Leonard's TED Talk, with over three and a half million views, demonstrates the power of accessible communication about complex legal concepts. Educators can use her framework to teach about environmental law, Indigenous rights, and ecological justice.

Adaptation Strategies for Different Contexts: In jurisdictions with strong Indigenous legal traditions, the framework can center Indigenous law as the foundation for water protection. In jurisdictions without such traditions, the framework can draw on international precedents and human rights law. At the international level, the framework can inform treaties, conventions, and the work of bodies like the IUCN, which adopted a motion in 2025 calling on governments to recognize nature's rights in law.

3.2 Common Misconceptions and How to Avoid Them

Misconception One: Legal Personhood Means Water Is Treated Exactly Like a Human. Some interpret legal personhood as claiming that rivers are the same as humans. In fact, legal personhood is a legal mechanism that grants rights and standing, not an assertion of human identity.

How to avoid: Emphasize that legal personhood is a flexible legal tool that can be adapted to different entities. A river as a legal person has river-specific rights—the right to flow freely, to be free from pollution, to sustain life—not human rights.

Misconception Two: This Is Just Symbolic. Some dismiss legal personhood as a symbolic gesture without practical effect. In fact, legal personhood creates enforceable rights and enables legal standing for nature.

How to avoid: Cite concrete examples of legal personhood leading to protection. The Whanganui River, the Río Atrato, and the Magpie River have all received legal recognition that has enabled protection and governance.

Misconception Three: This Is Anti-Human. Some assume that recognizing the rights of nature is opposed to human interests. In fact, ecological health and human well-being are interdependent. Every degraded river translates into unsafe drinking water, failed crops, and displacement.

How to avoid: Emphasize that rights of nature and human rights are complementary, not competing. Protecting water protects communities.

Misconception Four: Indigenous Knowledge Is Just Cultural, Not Legal. Some treat Indigenous water traditions as cultural heritage rather than as legitimate legal systems. Leonard's work challenges this by demonstrating that Indigenous legal traditions offer a foundation for international water policy-making.

How to avoid: Recognize that Indigenous legal systems are sophisticated, working legal systems that have governed human-nature relationships for millennia. They are not merely cultural artifacts but living law.

Misconception Five: Legal Change Is Enough. Some assume that granting legal personhood is the end of the work. In fact, legal change must be accompanied by enforcement, governance, and cultural transformation.

How to avoid: Emphasize that legal personhood is "the first step", not the final step. Implementation, guardianship, and ongoing advocacy are essential.

3.3 Key Insights for Readers and Practitioners

Shift Your Mindset from Resource to Relative: The most fundamental insight of Leonard's framework is the reframing of water from a resource to be managed to a relative to be honored. This shift transforms the entire relationship—from extraction to care, from ownership to kinship.

Understand That Law Is Not Neutral: The current legal framework that treats water as property is not neutral; it reflects specific values and power relations. Changing the law is a way of changing those values and relations.

Recognize the Power of Legal Personhood: Legal personhood is not merely a philosophical concept but a practical tool that can create enforceable rights and enable legal standing. As Leonard states, granting legal personhood to water "affords the following rights and protections. It grants water the right to exist".

Center Indigenous Legal Traditions: Indigenous peoples have maintained working legal systems for water protection for millennia. These systems offer a foundation for transforming international water policy-making. Supporting Indigenous sovereignty is essential for water justice.

Act Locally, Think Globally: The rights of nature movement is a global phenomenon, with legal innovations spreading across continents. Local action—whether through municipal ordinances, tribal laws, or advocacy campaigns—contributes to this global momentum.

Section Four: Summary and Outlook

4.1 Summary of Core Viewpoints

Kelsey Leonard's framework for legal personhood for water offers a powerful reimagining of the legal relationship between humanity and the natural world. By granting lakes and rivers legal personhood—the same legal rights as humans—we can protect our bodies of water and fundamentally transform how we value this vital resource. This framework is grounded in Indigenous legal traditions that recognize water not as a resource but as a relative, and it is informed by global precedents from New Zealand to Colombia to Canada to Spain. Legal personhood is not merely symbolic but a practical mechanism that grants water the right to exist, the right to be free from pollution, and the right to sustain life. By centering Indigenous legal traditions and challenging the anthropocentrism of Western law, Leonard's framework offers a pathway toward ecological justice and a transformed relationship with the natural world.

4.2 Future Development Trends and Outlook

The field of rights of nature is poised for significant growth, and Leonard's work points toward several promising directions.

Expanding Legal Recognition: The momentum behind rights of nature is growing. The 2025 IUCN World Conservation Congress adopted multiple motions calling on governments to recognize nature's rights in law. More countries, municipalities, and Indigenous nations are likely to grant legal personhood to water bodies in the coming years.

Deepening Implementation: As legal recognition expands, attention will shift to implementation. How can legal personhood translate into meaningful ecological protection? This will require governance mechanisms, enforcement, and accountability.

Strengthening Indigenous Leadership: Leonard's work demonstrates that Indigenous legal traditions must be central to the rights of nature movement. Future developments will likely involve stronger partnerships between Indigenous nations and settler governments, as seen in the Magpie River recognition.

Integrating with Climate Action: As climate change accelerates, the protection of water bodies becomes increasingly urgent. Rights of nature frameworks may be integrated with climate adaptation strategies, recognizing that healthy ecosystems are essential for climate resilience.

Addressing Critiques and Challenges: Scholars and practitioners will continue to grapple with questions about implementation, co-optation, and the limits of legal change. These critiques will sharpen the framework and strengthen its application.
