   MEMORANDUM

The parties are familiar with the facts of the case and we do not repeat them here. Proposed intervenors Janet U. Maratita and Jesus I. Taisague appeal the district court’s denial of their Ex Parte Motion to Lift Stay (Motion to Lift the Stay) for the purpose of pursuing a motion to intervene in a class action brought by Betty Johnson, on behalf of herself and similarly situated persons who were beneficiaries of the Commonwealth of the Northern Mariana Islands (CNMI) Defined Benefit Plan.

1. Every court possesses inherent power to “control the disposition of the causes on its docket with economy of time and effort,” which calls for the “exercise of judgment.” Landis v. N. Am. Co., 299 U.S. 248, 254, 57 S.Ct. 163, 81 L.Ed. 153 (1936). Accordingly, we review the district court’s denial of the Motion to Lift the Stay for abuse of discretion. Valdivia v. Schwarzenegger, 599 F.3d 984, 988 (9th Cir.2010). Under the abuse-of-discretion standard, we cannot reverse the district court order absent a “definite and firm conviction that the district court committed a clear error of judgment in the conclusion it reached upon a weighing of relevant factors.” Id.

2. The district court did not abuse its discretion in denying the Motion to Lift the Stay. The court reached its decision after considering: (1) the burden of litigation, (2) lack of changed circumstances, (3) gross underfunding of the Retirement Fund, and (4) the risk of placing 4,000 retirees’ benefits at further risk. In addition, the court did not err by requiring a showing of “changed circumstances” as a prerequisite for lifting the stay. The district court’s order demonstrates that the court considered the totality of the circumstances and properly exercised its discretionary power in refusing to lift the stay.

AFFIRMED.
