Is a judge's decision not to grant bail to a defendant who has not been granted bail?

judge's bail ruling. See United States v. Koenig, 912 F.2d 1190, 1191 (9th Cir. 1990). A district court "should review the evidence before the magistrate and make its own independent determination whether the magistrate's findings are correct, with no deference. If the performance of that function makes it necessary or desirable for the district judge to hold additional evidentiary hearings, it may do so, and its power to do so is not limited to occasions when evidence is offered that was not presented to the magistrate." Id. at 1193.
