Indigenous Tribes: Ask Judge to Block Trump-Era Alaska Oil Leases

• Indigenous tribes and environmental groups have asked a federal judge to block oil and gas leases in the Arctic National Wildlife Refuge's Coastal Plain.
• The lawsuit challenges the Trump administration's environmental analysis, alleging it downplayed impacts on polar bears and prioritized oil over other purposes.
• The Coastal Plain is a critical habitat for 120,000 caribou and threatened polar bears, and holds deep cultural significance for the Gwich'in people.
• The leasing program was initiated in 2020, paused by President Biden in 2024, and reinstated by the Trump administration in 2025 using the same contested environmental review.
• The legal status has progressed beyond arguments of prematurity, with Judge Gleason ruling in March 2025 that the Department of the Interior illegally canceled leases, leading to appeals and settlements regarding ANWR oil and gas leasing.

The Coastal Plain, often dubbed "America’s Serengeti," is a vital ecosystem, serving as a calving ground for approximately 120,000 caribou and a crucial denning area for polar bears, which are recognized as a threatened species under the Endangered Species Act.

A coalition of Indigenous tribes and environmental organizations recently petitioned a federal judge to halt the Trump administration's initiative to permit oil and gas exploration across the 1.56 million-acre Coastal Plain within Alaska's Arctic National Wildlife Refuge. This legal action, framed as a motion for summary judgment, seeks to block the proposed drilling, arguing that the U.S. Department of Interior's environmental assessment for the plan improperly prioritized energy development over other critical considerations.

Plaintiffs contend that the federal government's analysis of the plan's environmental impacts was flawed, specifically alleging that it "artificially inflated polar bears’ resiliency" and "ignored polar bears’ expected decline." Hannah Foster, an attorney representing the plaintiffs with Earthjustice, underscored the precarious state of polar bear populations. The lawsuit also highlights the profound cultural significance of the Coastal Plain for the Gwich'in people, who refer to themselves as "caribou people" due to their deep connection to the Porcupine caribou herd, whose calving grounds are located in this area, which they call "Iizhik Gwats’an Gwandaii Goodlit" or "the Sacred Place Where Life Begins."

The legislative foundation for opening the entire Coastal Plain to oil and gas leasing was established by Congress through a measure referred to as the "Big Beautiful Bill." The Trump administration initially implemented the leasing program in 2020, resulting in nine tracts being leased; seven went to the Alaska Industrial Development and Export Authority (AIDEA), a state agency, and two to private entities. However, in 2024, President Joe Biden temporarily suspended the program and the existing leases, citing various "alleged legal deficiencies."

Despite Biden's pause, the Trump administration subsequently reinstated the leasing program in 2025, relying on the identical environmental analysis that is now under scrutiny in the current Arctic National Wildlife Refuge drilling lawsuit. This re-establishment of the program, utilizing the previously challenged assessment, forms a central point of contention for the plaintiffs, who argue that the Department of Interior's initial review failed to adequately address the ecological and cultural ramifications of drilling in such a sensitive region.

The Coastal Plain, often dubbed "America’s Serengeti," is a vital ecosystem, serving as a calving ground for approximately 120,000 caribou and a crucial denning area for polar bears, which are recognized as a threatened species under the Endangered Species Act. While environmental and Indigenous groups emphasize the area's irreplaceable ecological and cultural value, energy industry estimates suggest the region holds between 4 billion and 12 billion barrels of technically recoverable oil.

Attorneys for the Department of Justice, representing the Department of the Interior, argued that the lawsuit was premature, asserting that it would be "years" before the issue would be ripe for judicial review, if ever. They maintained that the federal government had merely authorized the program and provided an analysis for a lease sale within the next five years, with exploration to follow. Michelle Nesbett, representing AIDEA, downplayed the potential impact on polar bears, stating that the project's effect would be "tiny" compared to climate change, which she identified as the primary threat. U.S. District Judge Sharon Gleason, an appointee of former President Barack Obama, has since ruled on key aspects of the Coastal Plain oil leases. In March 2025, Judge Gleason found that the Department of the Interior acted illegally by canceling existing leases without a court order, vacating the cancellation decision. The broader legal challenges have since progressed, with appeals filed by Alaska Native governments and environmental groups, and the U.S. Department of Justice settling related cases in July 2026 to loosen restrictions on ANWR oil and gas lease sales.

Lawyers advising energy companies, environmental organizations, or indigenous groups involved in resource development in Alaska should closely monitor this litigation. The outcome of the motion for summary judgment will determine the immediate legal viability of oil and gas leases in the Arctic National Wildlife Refuge's Coastal Plain, impacting future project planning, environmental compliance obligations, and potential precedent for similar challenges to federal land use decisions.
