Background

Lario Oil and Gas Company obtained a 2011 federal oil-and-gas lease from the Bureau of Land Management under the Mineral Leasing Act. Nine years later, BLM determined that portions of the leased acreage covered mineral interests held in trust for the Mandan, Hidatsa, and Arikara Nation.

BLM retroactively canceled the affected portions, refunded Lario’s associated payments and royalties, and did not convey the tribal mineral rights. Lario subsequently negotiated a new, BIA-approved lease with the MHA Nation, under which it paid higher bonuses and royalties, including retroactive payments for already produced oil and gas. Lario sued, alleging that the United States breached the original lease by canceling it.

The Court’s Holding

Judge Schwartz granted the government’s Rule 12(b)(6) motion to dismiss. Although the Court had Tucker Act jurisdiction, the claim failed because the original lease was void ab initio as to the MHA Nation’s land and therefore could not support contractual damages.

The Mineral Leasing Act did not authorize BLM to lease Indian land. Such leasing was governed by the Indian Mineral Leasing Act, under which the tribe—not the federal government—leases its mineral rights, subject to BIA approval and prescribed procedures. BLM executed the lease without BIA involvement, tribal participation, or compliance with IMLA procedures. Those defects meant the government lacked authority to enter the lease for the tribal acreage. The Court further held that invalidation was consistent with and essential to the IMLA’s purpose of protecting tribal mineral owners and tribal control over leasing.

Key Takeaways

  • A federal lease executed by the wrong bureau under the wrong statutory regime may be void ab initio, not merely breached.
  • IMLA procedures protect tribal control of mineral leasing and cannot be bypassed through a BLM lease issued under the Mineral Leasing Act.
  • A contractor bears the risk that a federal official lacked actual authority to bind the government.

Why It Matters

The ruling distinguishes an unauthorized lease of tribal minerals from a validly issued federal lease that later fails to convey the expected interest. Where the government lacks authority to lease the property at all, the lessee cannot recover expectancy damages on a breach-of-contract theory.

For companies operating near tribal lands, the decision underscores the need to confirm mineral ownership and the governing leasing regime before relying on a federal lease. A refund of payments may be the available remedy when an improperly issued lease is canceled.
