Long before tribal sovereignty became a familiar phrase in national courtrooms, Native lawyers were building the arguments, institutions, and legal strategies that made those victories possible.
They have defended treaty promises, protected Native children, reclaimed ancestral remains, restored jurisdiction, forced the federal government to account for trust funds, and trained the next generation of advocates. Their work is not one story and it does not belong to one Nation. It spans tribal courts, federal agencies, universities, nonprofits, and the United States Supreme Court.
This countdown spotlights 10 Indigenous legal minds whose careers show what law can become when it is used to uphold living nations instead of erasing them.
10. Robert J. Miller: Naming the legal architecture of colonization
Robert J. Miller, a citizen of the Eastern Shawnee Tribe, has spent decades examining a doctrine that still shapes Indigenous land and sovereignty disputes: the Doctrine of Discovery. His scholarship explains how European colonial powers converted religious and political claims into legal rules that restricted Indigenous property and governmental authority.
Miller is the Jonathan and Wendy Rose Professor of Law at Arizona State University and serves as chief justice of the Pascua Yaqui Tribe. By tracing the doctrine from its colonial roots to modern law, he gives lawyers and communities a clearer map of what they are challenging and why those old ideas still matter. His work turns a phrase many people have heard into a legal system they can recognize, question, and dismantle. Read his recent ASU-listed scholarship on the Doctrine of Discovery.
9. Heather Whiteman Runs Him: Bringing treaty rights into the courtroom
Heather Whiteman Runs Him, a citizen of the Crow Tribe, has worked across tribal government, public defense, national advocacy, and legal education. Before joining the University of Arizona, she represented tribal clients at the Native American Rights Fund and served as joint lead counsel for the Crow Tribe.
Her experience includes water, land, natural-resource, and treaty-rights work. She also appeared as counsel on a Crow Tribe brief in Herrera v. Wyoming, the 2019 Supreme Court case affirming that Wyoming statehood did not erase the Crow Tribe’s treaty hunting right. Today she is a clinical professor and directs Arizona Law’s Tribal Justice Clinic, where students work with tribal communities on real legal needs. See her current University of Arizona profile.
8. Stacy Leeds: Opening doors in legal education and tribal justice
Stacy Leeds, a citizen of the Cherokee Nation, made history in 2011 when she became the first Native American woman to lead a law school as dean at the University of Arkansas. That milestone is only one part of a career connecting classrooms, tribal courts, university leadership, and economic development.
Leeds also became the first woman to serve as a justice of the Cherokee Nation Supreme Court. At Arizona State University, she continues to teach and lead in Indian law and leadership. Her career matters because representation at the top of a law school changes more than a biography: it shapes who teaches, what scholarship receives support, and which students can imagine themselves belonging in the profession. ASU documents her trailblazing appointments.
7. Hilary Tompkins: Advising the federal government from lived experience
Hilary Tompkins, an enrolled member of the Navajo Nation, served from 2009 to 2017 as Solicitor of the U.S. Department of the Interior, the department’s chief lawyer. She was the first Native American to hold that office.
The role placed her at the legal center of federal land, water, energy, environmental, and Indian affairs decisions. Her path there was grounded in tribal law: before law school, she passed the Navajo Nation bar examination and worked as a tribal court advocate. That combination of federal responsibility and firsthand knowledge of tribal legal systems gave her a perspective rarely represented in the office. The Department of the Interior’s confirmation announcement details her background.
6. Matthew L.M. Fletcher: Building the field’s legal roadmap
Matthew L.M. Fletcher, a member of the Grand Traverse Band of Ottawa and Chippewa Indians, is one of the most influential scholars working in federal Indian law and tribal law today. At the University of Michigan, he teaches, writes, and serves on numerous tribal appellate courts.
Fletcher was lead reporter for the American Law Institute’s Restatement of the Law of American Indians, completed in 2022. A Restatement does not make law, but it can help judges, lawyers, and students understand a complicated body of cases and principles. He is also the primary editor and author of Turtle Talk, a widely used Indian law and policy resource. His work makes legal knowledge more accessible while keeping tribal courts and Native nations at the center of the conversation. Michigan Law lists his scholarship and judicial service.
5. Mary Kathryn Nagle: Protecting Native women, children, and jurisdiction
Mary Kathryn Nagle, a citizen of the Cherokee Nation, works where appellate law, tribal sovereignty, and storytelling meet. Her legal advocacy has focused on restoring safety and jurisdiction for Native women and children, including work connected to the Violence Against Women Act and the Indian Child Welfare Act.
Nagle is also an accomplished playwright. That matters because some of the hardest legal issues become clearer when people can hear the human consequences behind a jurisdictional rule. Through briefs, public advocacy, and theatre, she has helped audiences understand that tribal authority is not an abstract contest over power. It can determine whether a government is able to protect its own citizens. The National Indigenous Women’s Resource Center profiles her advocacy.
4. Keith M. Harper: Making the government account for trust money
Keith M. Harper, a citizen of the Cherokee Nation, served as class counsel in Cobell v. Salazar, the landmark case brought on behalf of approximately 500,000 individual Native trust beneficiaries. The lawsuit challenged the federal government’s management and accounting of Indian trust funds and ultimately resulted in a $3.4 billion settlement.
Harper later served from 2014 to 2017 as U.S. ambassador and permanent representative to the United Nations Human Rights Council, becoming the first Native American named a U.S. ambassador. His career connects a massive domestic accountability case with international human-rights diplomacy, showing how Indigenous rights arguments move between courtrooms, governments, and global institutions. His professional biography documents both roles.
3. Walter Echo-Hawk: Helping turn repatriation into federal law
Walter Echo-Hawk, Pawnee, is an attorney, author, tribal judge, and longtime advocate whose work has covered religious freedom, treaty rights, prisoner rights, water, and repatriation. He spent more than three decades with the Native American Rights Fund.
Echo-Hawk played an important role in the movement that led to the Native American Graves Protection and Repatriation Act of 1990. NAGPRA created a federal process for museums and agencies to return certain human remains and cultural items to lineal descendants, tribes, and Native Hawaiian organizations. The law emerged from years of work by Native religious leaders, communities, lawyers, and advocates; Echo-Hawk helped translate that movement into legal change. NARF’s legal review describes his service and NAGPRA work.
2. Arlinda Locklear: A Supreme Court barrier breaker
Arlinda Locklear, a member of the Lumbee Tribe of North Carolina, became the first Native American woman to argue a case before the U.S. Supreme Court when she appeared in Solem v. Bartlett. The Court’s 1984 decision rejected South Dakota’s attempt to treat part of the Cheyenne River Sioux Reservation as diminished for jurisdictional purposes.
She returned to the Supreme Court in the Oneida land claim litigation and spent decades working on tribal recognition, land, water, and sovereignty issues. Locklear’s career is more than a historic first. It is a record of sustained advocacy that helped make room for generations of Native women in federal Indian law. Duke Law traces her career and landmark arguments.
1. John Echohawk: Building an institution for Native rights
John Echohawk, Pawnee, has been with the Native American Rights Fund since its creation in 1970 and has served continuously as executive director since 1977. Few legal careers have shaped the infrastructure of modern federal Indian law so directly.
NARF has represented tribes and Native people in cases involving sovereignty, treaty rights, natural resources, voting, jurisdiction, and government accountability. Echohawk’s contribution is not a claim that one lawyer won every case. It is the harder, longer work of helping build and sustain an institution capable of fighting those cases across generations. In 2023, the American Bar Association recognized that lifelong civil-rights work with its Thurgood Marshall Award. NARF’s official profile records more than five decades of leadership.
The law is one arena of sovereignty
These lawyers, judges, scholars, and advocates did not create tribal sovereignty. Native nations have always possessed their own political authority, laws, and responsibilities. What these legal minds have done is defend that authority in systems that have repeatedly tried to restrict it.
Their stories also resist a simple hero narrative. Landmark victories are collective: clients take risks, communities organize, elders and cultural leaders guide the work, researchers build records, and teams of lawyers carry arguments through years of litigation. The names on this list matter, but so do the Native nations and movements that made the work possible.
