United States ex rel. Polansky v. Executive Health Resources, Inc., 599 U.S. 419 (2023), was a United States Supreme Court case in which the Court held that in a qui tam action filed under the False Claims Act, the United States may move to dismiss whenever it has intervened â whether during the seal period or later on. In assessing a motion to dismiss an FCA action over a relator's objection, district courts should apply Federal Rule of Civil Procedure 41(a), the rule generally governing voluntary dismissal of suits in ordinary civil litigation.
