Does a party have a right to interview and question an adverse witness?

2 Schleining's reliance on United States v. Opager, 589 F.2d 799 (5th Cir.1979) is misplaced. Opager does not create the right for a party to interview or question an adverse witness. Rather, in Opager, the government defied a court order requiring the government to disclose the location and identity of an informant. Id. at 804. The government openly disregarded the district court's order, and the Fifth circuit reversed the judgment for that reason. Id. at 805. Here, the district court did not order Edelman to be deposed.
