SCOTUSblog: Kellogg Brown & Root Services, Inc. v. United States ex rel. Carter
Holding: In a unanimous decision, the Supreme Court ruled that As shown by the WSLA’s text, structure, and history, the Act applies only to criminal offenses, not to civil claims like those in this case. The FCA’s first-to-file bar keeps new claims out of court only while related claims are still alive, not in perpetuity. Thus, dismissal with prejudice was not called for in this case.
