Qui tam relator James Stone brought an action against government contractor, Rockwell International Corporation, alleging that it violated the False Claims Act while operating a nuclear weapons plant.

The U.S. Government intervened, pursuant to the intervention provisions of the FCA, and together with the relator, filed a joint amended complaint alleging, among other things, that Rockwell committed environmental violations by storing leaky blocks of pondcrete—a form of processed toxic waste.

Rockwell appealed the judgment, and the Tenth Circuit affirmed in relevant part, but remanded for a determination of whether the relator had satisfied a statutory requirement of disclosing information underlying his claims to the government prior to bringing suit.

The United States Supreme Court granted certiorari on the limited original source issue.
