By way of background, there is a stark difference between so-called “protective orders” entered pursuant to the discovery provisions of Federal Rule of Civil Procedure 26, on the one hand, and orders to seal court records, on the other. Discovery concerns the parties' exchange of information that might or might not be relevant to their case. “Secrecy is fine at the discovery stage, before the material enters the judicial record.” Baxter Int'l, Inc. v. Abbott Labs., 297 F.3d 544, 545 (7th Cir. 2002). Thus, a district court may enter a protective order limiting the use or disclosure of discovery materials upon a mere showing of “good cause[.]” Fed. R. Civ. P. 26(c)(1). These orders are often blanket in nature, and allow the parties to determine in the first instance whether particular materials fall within the order's protection. The district court entered several such orders here.

“At the adjudication stage, however, very different considerations apply.” Joy v. North, 692 F.2d 880, 893 (2d Cir. 1982). The line between these two stages, discovery and adjudicative, is crossed when the parties place material in the court record. Baxter, 297 F.3d at 545. Unlike information merely exchanged between the parties, “[t]he public has a strong interest in obtaining the information contained in the court record.” Brown & Williamson Tobacco Corp. v. F.T.C., 710 F.2d 1165, 1180 (6th Cir. 1983). That interest rests on several grounds. Sometimes, the public's interest is focused primarily upon the litigation's result—whether a right does or does not exist, or a statute is or is not constitutional. In other cases—including “antitrust” cases, id. at 1179—the public's interest is focused not only on the result, but also on the conduct giving rise to the case. In those cases, “secrecy insulates the participants, masking impropriety, obscuring incompetence, and concealing corruption.” Id. And in any of these cases, the public is entitled to assess for itself the merits of judicial decisions. Thus, “[t]he public has an interest in ascertaining what evidence and records the District Court and this Court have relied upon in reaching our decisions.” Id. at 1181; see also, e.g., Baxter, 297 F.3d at 546.

*3 The courts have long recognized, therefore, a “strong presumption in favor of openness” as to court records. Brown & Williamson, 710 F.2d at 1179. The burden of overcoming that presumption is borne by the party that seeks to seal them. In re Cendant Corp., 260 F.3d 183, 194 (3d Cir. 2001). The burden is a heavy one: “Only the most compelling reasons can justify non-disclosure of judicial records.” In re Knoxville News–Sentinel Co., 723 F.2d 470, 476 (6th Cir. 1983). Moreover, the greater the public interest in the litigation's subject matter, the greater the showing necessary to overcome the presumption of access. See Brown & Williamson, 710 F.2d at 1179. For example, in class actions—where by definition “some members of the public are also parties to the [case]”—the standards for denying public access to the record “should be applied ... with particular strictness.” Cendant, 260 F.3d at 194. And even where a party can show a compelling reason why certain documents or portions thereof should be sealed, the seal itself must be narrowly tailored to serve that reason. See, e.g., Press–Enter. Co. v. Superior Court of California, Riverside Cnty., 464 U.S. 501, 509-11, 104 S.Ct. 819, 78 L.Ed.2d 629 (1984). The proponent of sealing therefore must “analyze in detail, document by document, the propriety of secrecy, providing reasons and legal citations.” Baxter, 297 F.3d at 548.

In like fashion, a district court that chooses to seal court records must set forth specific findings and conclusions “which justify nondisclosure to the public.” Brown & Williamson, 710 F.2d at 1176. That is true even if neither party objects to the motion to seal, as apparently neither did in Brown & Williamson. (There, our court “reach[ed] the question” of the district court's seal “on our own motion.” Id.) As our decision there illustrates, a court's obligation to explain the basis for sealing court records is independent of whether anyone objects to it. And a court's failure to set forth those reasons—as to why the interests in support of nondisclosure are compelling, why the interests supporting access are less so, and why the seal itself is no broader than necessary—is itself grounds to vacate an order to seal. Id.; see also United States v. Kravetz, 706 F.3d 47, 60 (1st Cir. 2013) (“Appellate courts have on several occasions emphasized that upon entering orders which inhibit the flow of information between courts and the public, district courts should articulate on the record their reasons for doing so”); SEC v. Van Waeyenberghe, 990 F.2d 845, 849 (5th Cir. 1993) (reversing because “[w]e find no evidence in the record that the district court balanced the competing interests prior to sealing the final order”).
