Heading: appellate standard of review

Text: 5 Alyeska argues on appeal that the district court erroneously applied a standard of review too deferential to the EPA Administrator and merely rubber stamped the subpoena enforcement request. We hold that the question whether the district court correctly limited the scope of judicial inquiry in the EPA subpoena enforcement proceeding is a question of law, reviewable de novo in this court. See United States v. McConney, 728 F.2d 1195, 1201 (9th Cir). (en banc), cert. denied, 469 U.S. 824, 105 S.Ct. 101, 83 L.Ed.2d 46 (1984). The application of that standard to the facts of this case is also reviewable de novo since appellate review requires consideration of legal concepts rather than an essentially factual inquiry. McConney, 728 F.2d at 1204.
