Virginia Uranium, Inc. v. Warren

Background

A private company found a very large uranium deposit under Coles Hill in Virginia and sought to mine it. Virginia’s legislature imposed a decades-old ban on uranium mining on private land, and the company sued, arguing the Atomic Energy Act (a federal law) preempts the state ban. Lower courts dismissed the company’s claim and the case reached this Court to resolve whether federal law overrides the state moratorium.

Reasoning

The Court focused on the text and structure of the Atomic Energy Act and long-standing practice. The Act requires federal licensing only after uranium is removed from the ground and otherwise regulates milling, tailings, and later steps in the fuel cycle. The majority concluded the Act does not occupy the field of conventional mining on private land and that Congress left mining regulation to the States. The Court rejected the company’s claim that the state law was an unlawful obstacle to federal objectives because the statute’s text and history show Congress intended to leave conventional mining to state control.

Real world impact

The decision lets Virginia keep its ban in place and prevents the mining company from forcing the state to issue permits under federal law. The opinion notes the federal government could acquire the site or regulate differently if it chose, but for now the state ban stands. The ruling clarifies that federal preemption under the Atomic Energy Act is limited where Congress did not provide for federal regulation.

Dissents or concurrances

Justice Ginsburg joined the judgment but wrote separately; Chief Justice Roberts dissented, arguing the ban was a pretext to regulate federally preempted milling and tailings safety and that courts must examine legislative purpose to prevent evasion of federal authority.
