Apache Stronghold Copper Mine Lawsuit: 2026 Guide

The Apache Stronghold copper mine lawsuit is one of the most significant religious freedom and indigenous rights cases in modern American history. It centers on whether the federal government can hand over Oak Flat, a sacred Apache site in Arizona, to a foreign mining company for copper extraction.

This fight has been brewing for over a decade. It pits ancient spiritual traditions against a proposed mine that would create a crater nearly two miles wide.

In this article, you will learn where the case stands in 2026, what the courts have ruled, how the legal arguments work, and whether Apache Stronghold can actually stop the mine. The stakes go far beyond Arizona. This case could reshape how the government treats sacred indigenous lands across the entire country.

One striking fact: the proposed mine would destroy a site where Apache people have held coming-of-age ceremonies for generations, turning it into a 1,000-foot-deep crater.

Apache Stronghold Copper Mine Lawsuit Overview

The Apache Stronghold copper mine lawsuit challenges the federal government’s plan to transfer sacred Apache land to Resolution Copper Mining for a massive underground copper mine. Apache Stronghold, a nonprofit led by former San Carlos Apache Tribe chairman Dr. Wendsler Nosie Sr., filed the lawsuit to block this land exchange.

The land at issue is Oak Flat, known in Apache as Chi’chil Bildagoteel. It sits within the Tonto National Forest in southeast Arizona, about 70 miles east of Phoenix.

Congress authorized the transfer in Section 3003 of the National Defense Authorization Act for Fiscal Year 2015 (NDAA). That provision directed the U.S. Forest Service to swap approximately 2,422 acres of federal land at Oak Flat to Resolution Copper in exchange for parcels of private land elsewhere in Arizona.

Apache Stronghold argues the transfer violates the Religious Freedom Restoration Act (RFRA) and the First Amendment’s Free Exercise Clause. The organization says mining would completely destroy the site and make traditional ceremonies impossible.

This is not a settlement case in the traditional sense. There is no payout pool or class of claimants. Instead, it is an injunction case. Apache Stronghold seeks a court order blocking the land transfer entirely.

Apache Stronghold Lawsuit Update 2026

As of 2026, the Apache Stronghold lawsuit remains one of the most closely watched cases involving indigenous religious rights in federal court. The case has gone through multiple rounds of litigation, and its trajectory depends heavily on whether the U.S. Supreme Court decides to weigh in.

In March 2024, the Ninth Circuit Court of Appeals, sitting en banc with an 11-judge panel, ruled 7 to 4 against Apache Stronghold. The majority held that RFRA does not protect against government actions on government-owned land, even if those actions destroy a sacred site.

Apache Stronghold petitioned the U.S. Supreme Court for review. As of early 2026, the petition remains a focal point of legal attention.

Meanwhile, the actual land transfer has been paused. The U.S. Forest Service has not completed the final environmental impact statement (EIS) required before the exchange can go through. This administrative step has created a de facto delay, even as the legal battle continues.

• The Ninth Circuit’s en banc ruling was issued in March 2024
• A cert petition was filed with the Supreme Court
• The Forest Service’s final EIS remains incomplete as of 2026
• No physical mining activity has begun at Oak Flat
• Congressional efforts to repeal Section 3003 have been introduced but have not passed

The bottom line: the lawsuit is not over. Multiple legal and administrative hurdles remain before any mining could begin.

Apache Stronghold v United States Case Summary

Apache Stronghold v. United States is a federal lawsuit filed to stop the transfer of Oak Flat from public ownership to Resolution Copper Mining. The case asks whether the government’s destruction of a sacred religious site violates federal religious freedom protections.

Apache Stronghold first sought a temporary restraining order and preliminary injunction in the U.S. District Court for the District of Arizona. The district court denied that request, finding that Apache Stronghold was unlikely to succeed on the merits.

The case then went to the Ninth Circuit Court of Appeals. A three-judge panel initially ruled 2 to 1 in favor of Apache Stronghold in 2022, finding that the land transfer would impose a “substantial burden” on Apache religious exercise under RFRA.

That victory was short-lived. The full Ninth Circuit agreed to rehear the case en banc. In the en banc decision, the majority reversed the panel ruling.

The dissenting judges wrote powerful opinions. Judge Berzon argued that destroying a sacred site to benefit a private mining company is exactly the kind of government overreach RFRA was designed to prevent.

Key Takeaway: The Apache Stronghold copper mine lawsuit has traveled from district court through the full Ninth Circuit and now sits at the doorstep of the U.S. Supreme Court, with the core question still unresolved.

Has the Apache Stronghold Case Reached the Supreme Court

Apache Stronghold filed a petition for certiorari with the U.S. Supreme Court, asking the justices to review the Ninth Circuit’s en banc decision. As of 2026, the Court has not yet issued a final decision on whether to take the case.

The cert petition raises a question the Supreme Court has never directly answered. Does RFRA protect Native Americans when the government plans to destroy their sacred sites on federal land? Lower courts have been split on how to interpret “substantial burden” in these situations.

Several amicus briefs have been filed supporting Apache Stronghold. Religious organizations, tribal nations, legal scholars, and civil liberties groups have urged the Court to take the case.

The stakes are enormous. If the Supreme Court grants cert, it would be the first time the justices directly address whether RFRA applies to sacred site destruction on public lands.

• Cert petition filed: Following the March 2024 en banc ruling
• Amicus support: Broad coalition of tribal, religious, and civil rights organizations
• Legal question presented: Whether RFRA’s “substantial burden” test applies when government action destroys a sacred site
• Potential impact: Could set binding precedent for all federal sacred site cases

If the Court declines to hear the case, the Ninth Circuit ruling stands. That would clear a major legal obstacle for the land transfer, though administrative steps would still need to be completed.

Apache Stronghold Court Ruling Explained

The most significant court ruling in this case came from the Ninth Circuit’s en banc panel in March 2024, which ruled 7 to 4 that Apache Stronghold’s RFRA claim fails. The majority reasoned that the government’s transfer of its own land does not impose a “substantial burden” on religious exercise as defined by RFRA.

The majority opinion drew a distinction between government actions that coerce someone to act against their religion and actions that simply make religious practice more difficult. The court said the land transfer falls into the second category.

Think of it this way. If the government told Apache people they could not pray, that would be coercion. But the government transferring land it already owns, even if it makes prayer at that location impossible, is different in the court’s view.

The four dissenting judges strongly disagreed. They argued that completely destroying a sacred site is the most extreme burden imaginable on religious practice.

The dissent called the majority’s reasoning “a license to destroy” Native American sacred sites. This sharp divide makes the case a strong candidate for Supreme Court review.

Oak Flat Copper Mine Legal Battle Background

The legal battle over Oak Flat dates back to 2014 when Congress quietly attached the land exchange provision to a must-pass defense spending bill. The provision was added as a last-minute rider to the National Defense Authorization Act for Fiscal Year 2015, signed into law by President Obama in December 2014.

For years before that, standalone legislation authorizing the land swap had failed to pass Congress on its own merits. Lawmakers who supported it could not get enough votes. So supporters attached it to the massive defense bill, where it attracted less scrutiny.

The land exchange provision had been pushed primarily by Arizona’s congressional delegation, with backing from Resolution Copper. The mining company had been exploring the Oak Flat area since the early 2000s.

Oak Flat had actually been protected from mining since 1955 under a presidential executive order. That protection held for nearly 60 years until the 2014 legislation overrode it.

• 1955: Executive order protects Oak Flat from mining claims
• Early 2000s: Resolution Copper begins exploration near Oak Flat
• 2005-2013: Multiple standalone land exchange bills fail in Congress
• December 2014: Section 3003 passes as rider on NDAA
• 2021: Apache Stronghold files lawsuit
• 2022-2024: Case moves through Ninth Circuit

The manner in which the provision passed has been controversial on its own. Critics say attaching it to a defense bill was a way to avoid democratic debate on an issue that deserved its own hearing.

Key Takeaway: Congress bypassed years of failed standalone legislation by attaching the Oak Flat land exchange to a defense spending bill in 2014, overriding protections that had been in place since 1955.

Resolution Copper Mine Lawsuit in 2026

The Resolution Copper mine project remains stalled in 2026, not just because of the lawsuit but because of incomplete federal environmental reviews. Even if the legal challenges fail, the mine cannot proceed until the U.S. Forest Service issues its final environmental impact statement (EIS) and completes the land exchange process.

Resolution Copper Mining LLC is a joint venture between two of the world’s largest mining companies: Rio Tinto (headquartered in London and Melbourne) and BHP Group (headquartered in Melbourne). These are not small operators. They are multinational corporations with combined revenues exceeding $100 billion annually.

The proposed mine would use a technique called block caving. This method involves collapsing underground rock formations to extract ore, which eventually causes the surface to sink. At Oak Flat, this would create a subsidence crater roughly two miles wide and up to 1,000 feet deep.

Resolution Copper has argued the mine would create thousands of jobs and produce copper essential for electric vehicles and renewable energy infrastructure. Opponents say no amount of economic benefit justifies destroying an irreplaceable sacred site.

Apache Stronghold RFRA Claim and Legal Strategy

Apache Stronghold’s primary legal argument rests on the Religious Freedom Restoration Act, a 1993 federal law that prohibits the government from substantially burdening a person’s religious exercise unless it can demonstrate a compelling reason and uses the least restrictive means. RFRA was designed to give religious practitioners stronger protections than the First Amendment alone provides.

The organization argues that transferring Oak Flat to a mining company will completely and permanently destroy the site where Apache people conduct sacred ceremonies, including the Sunrise Ceremony, a coming-of-age ritual for young women.

Apache Stronghold’s legal team contends this destruction meets the “substantial burden” test under RFRA. You cannot practice a ceremony tied to a specific place if that place becomes a giant crater.

The government’s counterargument relies heavily on a 1988 Supreme Court case called Lyng v. Northwest Indian Cemetery Protective Association. In Lyng, the Court ruled that the government building a road through a sacred forest did not violate the First Amendment because it did not coerce anyone to act against their beliefs.

• RFRA standard: Government cannot substantially burden religious exercise without a compelling interest and least restrictive means
• Apache Stronghold’s position: Total destruction of a sacred site is the ultimate substantial burden
• Government’s position: Lyng says government land management decisions do not trigger religious freedom protections
• Key tension: RFRA was passed partly to overrule the narrow reading of religious freedom in cases like Lyng

This tension between RFRA and Lyng is exactly why legal scholars believe the Supreme Court needs to resolve the question.

Oak Flat Mining and Religious Freedom Case

The Oak Flat case sits at the intersection of Native American religious freedom and federal land management, raising questions that have never been fully answered by the highest court. At its core, the case asks whether the government can hand sacred land to a private company for destruction when that destruction eliminates a living religious tradition.

Religious freedom in America has traditionally been interpreted through the lens of churches, synagogues, and mosques. Sacred sites tied to the land itself receive far less protection under existing law.

For Apache people, Oak Flat is not like a church building that could theoretically be rebuilt elsewhere. The spiritual significance is bound to the physical location itself. The springs, rock formations, and ancient oaks at Chi’chil Bildagoteel cannot be replicated.

This case has drawn attention from religious communities far beyond Native American traditions. Christian, Jewish, Muslim, Sikh, and Buddhist organizations have filed amicus briefs supporting Apache Stronghold, recognizing that a ruling against sacred site protections could affect all faiths.

The breadth of religious support for Apache Stronghold signals that this is not seen as a niche tribal issue. It is viewed as a test case for religious freedom itself.

Key Takeaway: The Oak Flat case tests whether America’s religious freedom laws protect sacred sites tied to the land, a question with implications for every faith tradition, not just Native American religions.

Who Is Apache Stronghold

Apache Stronghold is a nonprofit coalition of current and former San Carlos Apache Tribe members, other Native Americans, and non-Native supporters who are working to protect Oak Flat from mining. The organization was founded by Dr. Wendsler Nosie Sr., a former chairman of the San Carlos Apache Tribe.

Dr. Nosie has been one of the most visible and vocal figures in the fight to save Oak Flat. He has camped at the site, organized prayer runs, and spoken before Congress, federal agencies, and international bodies about the importance of the land.

Apache Stronghold operates independently from the San Carlos Apache Tribe’s formal government. While the Tribe has expressed opposition to the mine, the Tribe and Apache Stronghold are separate legal entities with their own strategies and priorities.

The organization has built a broad coalition of supporters. Environmental groups, religious organizations, indigenous rights advocates, and civil liberties organizations have all joined the effort.

• Founded by: Dr. Wendsler Nosie Sr.
• Type: Nonprofit organization
• Mission: Protect Oak Flat and other sacred Apache sites
• Relationship to San Carlos Apache Tribe: Independent but aligned in opposition to the mine
• Coalition partners: Include religious groups, environmental organizations, and tribal nations

Apache Stronghold’s legal team has included attorneys from the Becket Fund for Religious Liberty, one of the most prominent religious freedom law firms in the country. Becket has represented clients across the religious spectrum, from Christian organizations to Sikh, Muslim, and Native American plaintiffs.

What Is Resolution Copper Mine in Arizona

Resolution Copper Mine is a proposed underground copper mine in the Tonto National Forest near the town of Superior, Arizona, approximately 60 miles east of Phoenix. If built, it would be one of the largest copper mines in North America.

The project is owned by Resolution Copper Mining LLC, a joint venture between Rio Tinto (55% ownership) and BHP Group (45% ownership). Both are among the world’s largest mining companies.

Resolution Copper says the deposit contains enough copper to supply about 25% of U.S. copper demand for several decades. That is a significant claim at a time when copper demand is surging due to electric vehicle production and renewable energy infrastructure.

The mine would operate roughly 7,000 feet underground, using the block caving method. This technique is less expensive than traditional underground mining but causes the surface above to collapse over time.

Resolution Copper has spent over two decades and more than $2 billion developing the project. The company maintains that the mine can coexist with cultural preservation, though critics find that claim impossible to square with the projected crater.

Oak Flat Sacred Site Mining Dispute Explained

Oak Flat, known in Western Apache as Chi’chil Bildagoteel, is a roughly 6.7-square-mile area of high desert dotted with ancient Emory oaks, natural springs, and distinctive rock formations. For the San Carlos Apache and other Apache peoples, it is one of the most sacred sites in their spiritual tradition.

The area has been used for ceremonies, prayers, and gathering for centuries. The Sunrise Ceremony, or na’ii’ees, is performed here for young Apache women transitioning to adulthood. It is a multi-day ceremony deeply connected to the specific geography of Oak Flat.

Beyond its spiritual significance, Oak Flat has been listed on the National Register of Historic Places. Archaeological surveys have identified artifacts and cultural features throughout the area.

The dispute boils down to a fundamental conflict. Resolution Copper sees the land as sitting atop a world-class copper deposit worth billions. Apache people see the land as a living cathedral that cannot be replaced.

• Apache name: Chi’chil Bildagoteel (meaning “land of the acorns”)
• Location: Tonto National Forest, southeast Arizona
• Size: Approximately 6.7 square miles in the broader area of concern
• Key ceremonies: Sunrise Ceremony (na’ii’ees)
• Historic designation: Listed on the National Register of Historic Places
• Mining impact: Complete destruction of the surface through subsidence

There is no middle ground in this dispute. Block caving would collapse the surface entirely. You cannot mine the copper and preserve the land. It is one or the other.

Key Takeaway: Oak Flat cannot be partially mined and partially preserved; the block caving method would collapse the entire surface, making this a zero-sum conflict between copper extraction and sacred site preservation.

Resolution Copper Land Exchange Lawsuit Details

The land exchange at the heart of this case was mandated by Section 3003 of the National Defense Authorization Act for Fiscal Year 2015. Under the provision, the U.S. Forest Service must transfer approximately 2,422 acres at Oak Flat to Resolution Copper. In return, Resolution Copper would give the government roughly 5,344 acres of private land at various locations across Arizona.

The exchange cannot happen until the Forest Service completes a final environmental impact statement (EIS). The agency published a draft EIS in 2019 and a final EIS in January 2021. However, the Forest Service later withdrew the final EIS in March 2021 under the Biden administration, citing concerns about the adequacy of tribal consultation.

As of 2026, the EIS process has not been completed. This administrative pause has been as effective as any court order in delaying the land exchange.

The exchange provision includes a 60-day clock. Once the final EIS is published, the land transfer must happen within 60 days. That is why the status of the EIS is so important. Completing it would start an almost automatic process.

Some legal observers have noted that a future administration could restart the EIS process and move quickly to finalize the exchange. The legal and administrative battlegrounds are intertwined.

Oak Flat Copper Mine Lawsuit Timeline

The Oak Flat copper mine lawsuit has a long and complex history spanning over a decade of legislative, administrative, and judicial action. Here is a detailed timeline of the key events.

Each stage of this timeline represents a turning point. The 2022 panel victory gave Apache Stronghold hope. The en banc reversal was a blow. The Supreme Court petition represents what may be the final legal avenue.

What makes this timeline unusual is the parallel administrative track. Even as courts ruled, the EIS withdrawal created a separate pause. Both tracks would need to resolve in the government’s favor before mining could begin.

Resolution Copper Environmental Impact Concerns

The environmental impact of the Resolution Copper mine would be severe and permanent, according to the government’s own draft environmental analysis. The block caving mining method would cause the surface to collapse, creating a subsidence crater that federal documents estimate could reach approximately 1.8 miles wide and 800 to 1,000 feet deep.

That crater would swallow not just Oak Flat itself but surrounding areas as well. The collapse would be gradual, happening over the projected 40-to-60-year mine life, but the end result would be irreversible.

Water is another major concern. Southeast Arizona is already arid. The mine would require enormous amounts of water and could affect local aquifers and downstream water users.

• Subsidence crater: Up to 1.8 miles wide, 800 to 1,000 feet deep
• Water use: Massive water requirements in an already water-stressed region
• Tailings storage: Large tailings facilities would be needed to store mining waste
• Biodiversity: Habitat loss for native plant and animal species
• Air quality: Dust and particulate matter from mining operations
• Cultural resources: Permanent destruction of archaeological and cultural sites

The draft EIS identified multiple environmental concerns but concluded the mine could proceed with mitigation measures under certain alternatives. Environmental groups have argued those mitigation measures are inadequate for impacts of this scale.

It is worth remembering that the environmental review was withdrawn before being finalized. Any future version would need to address these concerns, and potentially new ones, all over again.

Key Takeaway: The government’s own environmental review found the Resolution Copper mine would create a permanent crater nearly two miles wide and a thousand feet deep, destroying Oak Flat and affecting water resources across southeast Arizona.

Apache Stronghold Legal Rights Over Sacred Land

Apache Stronghold’s legal claim to protect Oak Flat rests on federal religious freedom law, not on property ownership or tribal sovereignty. This distinction matters because the land is currently owned by the federal government, not by the San Carlos Apache Tribe or any other tribal nation.

Under RFRA, the question is not who owns the land. The question is whether a government action substantially burdens someone’s religious exercise. Apache Stronghold argues that their members have practiced religious ceremonies at Oak Flat for generations, and destroying the site would end that practice forever.

The legal framework creates an unusual situation. Apache people do not need to own Oak Flat to have religious rights there. They need to demonstrate that the government’s action, transferring the land for mining, would substantially burden their sincere religious practices.

The Ninth Circuit majority, however, drew a line. It said the government disposing of its own property is categorically different from the government punishing someone for practicing their religion. The dissent called this distinction “devastating” for indigenous religious practitioners.

If the Supreme Court agrees with the dissent, it could establish that RFRA protects religious practices tied to specific locations on public land. That would be a historic expansion of indigenous religious rights.

Can Apache Stronghold Stop the Mine

Apache Stronghold can potentially stop the mine, but the path forward is narrow and depends on either a Supreme Court victory or continued administrative delays. No single legal or political action is guaranteed to permanently block the project.

There are several ways the mine could be stopped or further delayed:

Legal path: If the Supreme Court takes the case and rules that RFRA protects sacred sites from government destruction, the land transfer would be blocked. This is the most definitive outcome Apache Stronghold seeks.

Administrative path: The Forest Service’s final EIS remains incomplete. Without it, the 60-day land transfer clock cannot start. A sympathetic administration could delay or complicate this process for years.

Legislative path: Members of Congress have introduced bills to repeal Section 3003 of the NDAA. The Save Oak Flat Act has been introduced in multiple congressional sessions but has not passed. A successful repeal would permanently block the exchange.

The most durable protection would come from either a Supreme Court ruling or an act of Congress. Administrative actions, while effective in the short term, can be reversed when political leadership changes.

Resolution Copper has invested over $2 billion and has powerful corporate backers. The company is unlikely to abandon the project voluntarily. This fight will continue until one of these paths reaches a definitive conclusion.

Key Takeaway: Apache Stronghold has legal, administrative, and legislative paths to stop the mine, but each carries significant uncertainty, and only a Supreme Court ruling or congressional repeal would provide permanent protection.

Apache Stronghold argues the transfer violates the Religious Freedom Restoration Act and the First Amendment.
The case raises the question of whether federal religious freedom laws protect sacred indigenous sites on public land.

Did Apache Stronghold win or lose the lawsuit in 2026?

Apache Stronghold lost at the Ninth Circuit en banc level in March 2024, with the court ruling 7 to 4 against their claims.
The organization has petitioned the U.S. Supreme Court for review, and that petition remains pending as of 2026.
The case is not fully resolved because the Supreme Court has not yet decided whether to hear it.

Is the Oak Flat copper mine currently being built?

No, the Oak Flat copper mine is not currently being built and no mining activity has begun at the site.
The U.S. Forest Service withdrew its final environmental impact statement in March 2021, and the review process remains incomplete.
Until the EIS is finalized and the land exchange is executed, mining cannot proceed.

Can the Supreme Court stop the Resolution Copper mine?

Yes, the Supreme Court could effectively stop the mine by ruling that the land transfer violates RFRA.
Such a ruling would block the land exchange and set a national precedent for sacred site protection.
The Court must first agree to hear the case by granting the cert petition filed by Apache Stronghold.

How does the Apache Stronghold case affect other sacred site disputes?

A Supreme Court ruling in this case would set binding precedent for how federal religious freedom laws apply to sacred sites on public land nationwide.
A ruling for Apache Stronghold could strengthen protections for indigenous sacred sites across the country.
A ruling against Apache Stronghold would make it significantly harder for any tribal nation to use RFRA to protect sacred places from federal government actions.

The Apache Stronghold copper mine lawsuit remains unresolved in 2026, with the Supreme Court petition representing the most significant remaining legal avenue. The parallel administrative delay, caused by the incomplete environmental review, provides additional time but no permanent protection.

If you care about this case, watch for two things: whether the Supreme Court grants cert, and whether the Forest Service restarts the environmental review process. Both developments could happen at any time and would dramatically change the trajectory of this fight.

Stay informed. The outcome here will affect sacred site protections, religious freedom law, and indigenous rights for generations.
