This decision holds that the US DOJ may move to dismiss a False Claims Act suit whenever it has intervened in the litigation, whether during the period the complaint remained sealed or thereafter.  However, the government must give the relator notice and an opportunity to be heard regarding the dismissal.  In deciding whether to approve dismissal, the court must apply FRCP 41(a) standards, considering the relator’s investment, but, absent extraordinary circumstances, approving the dismissal so long as the DOJ supplies good grounds for thinking that the suit does not vindicate the government’s interests.
