What is the test for abuse of power in the context of a motion for reconsideration from the district court?

We review plaintiffs' appeal from the district court's denial of their motion for reconsideration for abuse of discretion, see, e.g., Legg v. Ulster County, 820 F.3d 67, 78 (2d Cir. 2016), and identify none. Plaintiffs' contention that the district court erred in disregarding their constitutional challenge to 43 U.S.C. 1457raised for the first time in their motion for reconsiderationis meritless. The district court's passing reference to that statute supported only the proposition that "[t]he Secretary is delegated broad authority over Indian affairs." Pls' App'x 3-4, 16. It was not, contrary to plaintiffs' suggestion, a material ground for the court's decision.
