On what basis will a federal district court be required to consider the type and amount of evidence it deems relevant to a motion?

On the other hand, requiring the district court to consider certain factors grants the court broad discretion to determine the type and amount of evidence it deems relevant. We have no authority to modify the statutory scheme by narrowing that discretion. "The test is whether the district court complied with the applicable [statute]. If the [statute] do[es] not require a detailed explanation of the court's decision, the district court need not volunteer one...." United States v. Gomez, 846 F.2d 557, 560 (9th Cir.1988).
