Text: Amicus’ arguments to the contrary have aided our consideration of this case. But they do not persuade us that de novo review is appropriate.

Amicus’ central argument is that the decision whether a subpoena should be enforced does not require the exercise of discretion on the part of the district court, and so it should not be reviewed for abuse of discretion. On amicus’ view, the district court’s primary role is to test the legal sufficiency of the subpoena, not to weigh whether it should be enforced as a substantive matter. Cf. Shell Oil, 466 U.S., at 72, n. 26 (rejecting the argument that the district court should assess the validity of the underlying claim in a proceeding to enforce a subpoena). Even accepting amicus’ view of the district court’s task, however, this understanding of abuse-of-discretion review is too narrow. As commentators have observed, abuse-of-discretion review is employed not only where a decisionmaker has “a wide range of choice as to what he decides, free from the constraints which characteristically attach whenever legal rules enter the decision[making] process”; it is also employed where the trial judge’s decision is given “an unusual amount of insulation from appellate revision” for functional reasons. Rosenberg, Judicial Discretion of the Trial Court, Viewed From Above, 22 Syracuse L. Rev. 635, 637 (1971); see also 22 C. Wright & K. Graham, Federal Practice and Procedure §5166.1 (2d ed. 2012). And as we have explained, it is in large part due to functional concerns that we conclude the district court’s decision should be reviewed for abuse of discretion. Even if the district court’s decision can be characterized in the way that amicus suggests, that characterization would not be inconsistent with abuse-of-discretion review.

Nor are we persuaded by amicus’ remaining arguments. Amicus argues that affording deferential review to a district court’s decision would clash with Court of Appeals decisions instructing district courts to defer themselves to the EEOC’s determination that evidence is relevant to the charge at issue. See Director, Office of Thrift Supervision, v. Vinson & Elkins, LLP, 124 F.3d 1304, 1307 (CADC 1997) (district courts should defer to agency appraisals of relevance unless they are “obviously wrong”); EEOC v. Lockheed Martin Corp., Aero & Naval Systems, 116 F.3d 110, 113 (CA4 1997) (same). In amicus’ view, it is “analytically impossible” for the court of appeals to defer to the district court if the district court must itself defer to the agency. Tr. of Oral Arg. 29. We think the better reading of those cases is that they rest on the established rule that the term “relevant” be understood “generously” to permit the EEOC “access to virtually any material that might cast light on the allegations against the employer.” Shell Oil, 466 U.S., at 68–69. A district court deciding whether evidence is “relevant” under Title VII need not defer to the EEOC’s decision on that score; it must simply answer the question cognizant of the agency’s broad authority to seek and obtain evidence. Because the statute does not set up any scheme of double deference, amicus’ arguments as to the infirmities of such a scheme are misplaced.

Nor do we agree that, as amicus suggests, the constitutional underpinnings of the Shell Oil standard require a different result. To be sure, we have described a subpoena as a “ ‘constructive’ search,” Oklahoma Press, 327 U.S., at 202, and implied that the Fourth Amendment is the source of the requirement that a subpoena not be “too indefinite,” Morton Salt, 338 U.S., at 652. But not every decision that touches on the Fourth Amendment is subject to searching review. Subpoenas in a wide variety of other contexts also implicate the privacy interests protected by the Fourth Amendment, but courts routinely review the enforcement of such subpoenas for abuse of discretion. See, e.g., United States v. Nixon, 418 U.S. 683, 702 (1974) (pretrial subpoenas duces tecum); In re Grand Jury Subpoena, 696 F.3d 428, 432 (CA5 2012) (grand jury subpoenas); In re Grand Jury Proceedings, 616 F.3d 1186, 1201 (CA10 2010) (same). And this Court has emphasized that courts should pay “great deference” to a magistrate judge’s determination of probable cause, Gates, 462 U.S., at 236 (internal quotation marks omitted)—a decision more akin to a district court’s preenforcement review of a subpoena than the warrantless searches and seizures we considered in Ornelas v. United States, 517 U.S. 690 (1996), on which amicus places great weight. The constitutional pedigree of Shell Oil does not change our view of the correct standard of review.
