National-Security Exception Permits a Narrow, Identity-Only Prior Restraint in Civil Litigation (and Makes It Immediately Appealable as an Injunction)

Introduction

In Baby Doe v. Joshua Mast (4th Cir. Apr. 22, 2026), the Fourth Circuit confronted an unusual collision between First Amendment doctrine and the practical realities of post-Afghanistan evacuation litigation. The plaintiffs—Baby Doe and John and Jane Doe (Afghan nationals living in North Carolina, proceeding by pseudonym)—sought to prevent the defendants (Joshua Mast, Stephanie Mast, and Richard Mast) from publicly disclosing information that could identify the Does or their family members in Afghanistan. The district court entered a protective order barring disclosure of identifying information unless the recipient first signed a non-disclosure agreement (NDA), and later refused to vacate or modify that order.

The defendants appealed, arguing that the order was an unconstitutional content-based prior restraint because it restricted speech about information they knew independent of discovery. The appeal also presented a threshold jurisdictional dispute: whether such a protective order is an “injunction” immediately appealable under 28 U.S.C. § 1292(a)(1). Judge Richardson, joined by Chief Judge Diaz, affirmed; Judge King dissented on jurisdictional grounds.

Key issues

Appellate jurisdiction: Is the denial of a motion to modify this type of protective order immediately appealable under § 1292(a)(1)?
First Amendment: Is an order restricting disclosure of identities a content-based prior restraint, and if so, can it survive strict scrutiny?
National security: Can protecting perceived U.S. collaborators and the credibility of U.S. confidentiality assurances qualify as a compelling interest?
Due process vagueness: Is the phrase “directly or indirectly identifies” unconstitutionally vague?

Summary of the Opinion

The Fourth Circuit held:

Jurisdiction exists under § 1292(a)(1): The order has the practical effect of an injunction because it restrains out-of-court speech to “any person” and threatens irreparable First Amendment injury that cannot be remedied after final judgment.
The order is a content-based prior restraint: Because it restricts speech based on content (identifying information) and operates in advance of speech, it triggers strict scrutiny; the deferential discovery-based standard of Seattle Times Co. v. Rhinehart does not apply.
The order survives strict scrutiny under a narrow national-security exception: The government’s compelling interest in national security includes maintaining credible confidentiality assurances to foreign sources and potential collaborators (and those perceived as such). The order is narrowly tailored because it targets only identifying information, applies only to litigants, and permits disclosure with NDAs.
The order is not unconstitutionally vague: “Directly or indirectly identifies” provides adequate notice and enforceable standards, particularly in a civil-contempt setting.

Analysis

Precedents Cited

1) Interlocutory appellate jurisdiction and “injunction” practical effect

Mitchell v. Maurer and Bowles v. Russell: The majority emphasizes the court’s obligation to confirm jurisdiction and the jurisdictional nature of appeal deadlines.
FTC v. Minneapolis-Honeywell Regul. Co.: A later order does not restart the appeal clock for the original order; the defendants could not directly appeal the 2022 order, but could appeal the 2024 refusal to modify it.
Abbott v. Perez and Selective Ins. Co. of America v. Westfield Ins. Co.: The “practical effect” test governs whether an order is treated as an injunction for § 1292(a)(1).
United States ex rel. Lutz v. United States, Carson v. Am. Brands, Inc., and In re Braxton: The majority applies the Fourth Circuit’s two-part refinement—serious/irreparable consequences and the need for immediate appeal.
Elrod v. Burns, CBS, Inc. v. Davis, In re Murphy-Brown, LLC, and Roman Catholic Diocese of Brooklyn v. Cuomo: The majority treats loss of speech rights during litigation as irreparable, making post-judgment review inadequate.
Parker v. Columbia Broad Sys., Inc. and Bailey v. Sys. Innovation, Inc.: Sister-circuit support for treating party-speech restraints as appealable injunctions.
Dissent’s reliance on Gulfstream Aerospace Corp. v. Mayacamas Corp.: Judge King views the protective order as a litigation-management directive rather than an injunction. The majority distinguishes Gulfstream as involving a classic stay/case-sequencing order confined to litigation conduct, whereas this order reaches broadly to speech “to any person, in any forum.”
Collateral order doctrine cases in the dissent: Cohen v. Beneficial Indus. Loan Corp., Doe v. Pub. Citizen, Doe v. Sidar, and Doe v. Vill. of Deerfield. The dissent argues the order is reviewable after final judgment and thus not immediately appealable; the majority instead anchors jurisdiction in § 1292(a)(1).

2) Pseudonymity vs. restraining speech: separating the tests

James v. Jacobson and United States v. Doe: The district court relied on James to justify both pseudonymity and the protective order. The majority’s key doctrinal move is to reject that linkage: James balances privacy, public access, and fairness within the litigation record; it does not authorize suppressing a defendant’s extrajudicial speech. The majority also cites Doe v. Sidar to reinforce that James governs anonymity decisions, not First Amendment prior restraints.

3) Prior restraint doctrine and strict scrutiny framework

Reed v. Town of Gilbert and Reno v. ACLU: Content-based restraints are presumptively unconstitutional and must satisfy strict scrutiny.
In re Murphy-Brown, LLC: Provides the Fourth Circuit’s modern template for analyzing judicial gag orders as content-based prior restraints subject to strict scrutiny; also supplies caution that such restraints should be “a last resort.”
Alexander v. United States: Confirms that court orders forbidding speech are “classic examples” of prior restraints.
Seattle Times Co. v. Rhinehart: The majority treats Seattle Times as limited to restrictions on dissemination of information obtained through court-compelled discovery. Because the defendants already knew the Does’ identities pre-suit, Seattle Times does not supply a deferential “good cause” standard.
Near v. Minnesota ex rel. Olson, S.E. Promotions, Ltd. v. Conrad, and Times Film Corp. v. City of Chicago: The majority invokes the “narrow exceptions” principle: prior restraints are ordinarily forbidden, but may be permissible in exceptional categories, including national security.
Neb. Press Ass'n v. Stuart, Sheppard v. Maxwell, and N.Y. Times Co. v. United States: The opinion acknowledges fair-trial-related restraint as a distinct (and heavily burdened) context, but the present case turns instead on national security.
Williams-Yulee v. Florida Bar: Strict scrutiny does not demand perfect tailoring, only narrow tailoring; used to defend the order’s design against hypothetical alternatives.

4) National security as a compelling interest—protecting sources and the “appearance” of confidentiality

Haig v. Agee: National security is “obvious and unarguable” as a compelling interest.
Snepp v. United States: The opinion relies heavily on Snepp’s emphasis that not only secrecy, but the “appearance of confidentiality,” is critical to effective foreign intelligence operations.
CIA v. Sims: The court adapts Sims’s logic about chilling cooperation even from “a small chance” of disclosure—here, to support restricting identification that could endanger perceived collaborators and thereby deter future cooperation.
United States v. Zubaydah: Cited for the proposition that confirmation/denial of sensitive relationships can reduce future cooperation by foreign partners.
United States v. Smith: Supports protection of “sources and methods” and, by extension, the identity-related information that could expose those sources.
Agee (again): Used to connect foreign policy with national security, resisting any effort to narrow the government’s compelling interest to immediate battlefield concerns alone.

5) Vagueness doctrine

FCC v. Fox Television Stations, Inc., Johnson v. United States, and Lumumba v. Kiser: Provide the two-part vagueness test (fair notice; prevention of arbitrary enforcement) and heightened concern where speech is burdened.
Hoffman Estates v. Flipside, Hoffman Estates, Inc.: Notes stricter scrutiny in speech contexts but also greater tolerance where penalties are civil rather than criminal.
United States v. Williams, Ward v. Rock Against Racism, and Recht v. Morrisey: Emphasize that “perfect clarity” is not required.
Schleifer v. City of Charlottesville: “Minimal guidelines” and “reasonable notice” suffice.
Broadrick v. Oklahoma, United States v. Ehsan, and Dep't of Conservation & Dev. v. Tate: The Fourth Circuit uses these to normalize “directly or indirectly” language as constitutionally serviceable.

Legal Reasoning

1) The court’s jurisdictional holding: speech-restrictive “protective orders” can be injunctions

The majority’s first major contribution is jurisdictional. It treats an order restricting a party’s out-of-court speech as an injunction for § 1292(a)(1) purposes when the order reaches beyond internal case management and imposes externally operative, contempt-backed restraints. Applying the “practical effect” framework, the majority finds:

Serious/irreparable consequence: restrained speech is irreparable injury under Elrod and related cases.
No effective later review: a post-judgment win cannot restore the lost opportunity to speak during the litigation window.

This reasoning operationalizes a functional line between (a) orders that merely shape litigation conduct (discovery schedules, consolidation, sequencing) and (b) orders that regulate speech in the public sphere.

2) The court’s First Amendment framework: pseudonymity is not a shortcut to censorship

The majority’s second major contribution is doctrinal clarity: it separates the James v. Jacobson pseudonymity inquiry from the First Amendment prior-restraint inquiry. The district court had treated the speech restriction as a “corollary” of allowing pseudonyms. The Fourth Circuit rejects that as an “end-run” around the First Amendment. In effect, the opinion insists on a two-step analysis:

Step one: may the plaintiff litigate under a pseudonym? (the James balance)
Step two: may the court restrict what the defendant can say outside court? (prior restraint + strict scrutiny)

3) Why strict scrutiny is triggered: content-based prior restraint beyond discovery

The court holds the order is content-based (it targets speech that reveals identities) and is a prior restraint (it forbids speech before it occurs, backed by contempt). It also stresses that Seattle Times Co. v. Rhinehart is inapplicable because that case covers limits on disseminating discovery-produced information—information obtained by invoking the court’s coercive processes. Here, the defendants allegedly knew identities and background facts independently of discovery, so the order is a “classic” prior restraint requiring strict scrutiny.

4) Compelling interest: national security includes credibility of confidentiality assurances

The opinion’s most novel substantive move is to frame the compelling interest not merely as personal safety for the Does (though that is factually central), but as national security—specifically, the government’s interest in protecting foreign sources and maintaining credible confidentiality assurances that enable recruitment and cooperation. Relying on Haig v. Agee, Snepp v. United States, and CIA v. Sims, the majority reasons that:

Even perceived collaboration can trigger retaliation, so credibility requires protecting those plausibly seen as U.S. allies.
The “appearance of confidentiality” matters; if confidentiality looks porous, future sources “close up like a clam” (the Sims logic).
Therefore, preventing public identification can serve a compelling governmental interest, even in private civil litigation.

5) Narrow tailoring: identity-only restraint with NDA outlet

The majority finds the order is the least restrictive means available on this record because it is limited in several dimensions:

Subject-matter scope: it targets only information that directly or indirectly identifies the Does or family members.
Speaker scope: it binds only the defendants and their agents (litigation participants), not the press or the public.
Outlet preserved: disclosure can occur if the recipient signs an NDA enforceable by contempt.
Speech largely intact: defendants may discuss the case publicly so long as they do not reveal identities.

The court also rejects alternative proposals (e.g., restricting only media communications, or only communications likely to reach the Taliban) as unadministrable and not required by strict scrutiny, which does not demand “perfectly tailored” rules (Williams-Yulee).

6) Vagueness: “directly or indirectly identifies” is enforceable

The court rejects the vagueness challenge, citing multiple authorities approving “directly or indirectly” formulations. It frames the operative command as practical and comprehensible: do not disclose information that gives away identities unless an NDA is in place. The court also notes that the defendants’ conduct reflected their understanding of what was prohibited, reinforcing fair notice.

Impact

Interlocutory review expansion (within § 1292(a)(1)): The decision strengthens the argument that speech-restrictive protective orders aimed at extrajudicial communications are appealable as injunctions, distinguishing them from ordinary case-management orders.
Two-track doctrine for anonymity and speech: Litigants and courts in the Fourth Circuit should expect that permitting pseudonyms under James v. Jacobson does not itself justify restraining opponents’ speech; a separate prior-restraint analysis is required.
National-security rationale in private civil litigation: The opinion supplies a blueprint for invoking national security as a compelling interest where disclosure could endanger perceived collaborators and undermine confidence in U.S. confidentiality assurances, even when the government is not the party seeking the restraint.
Drafting guidance for future orders: Orders most likely to survive strict scrutiny will be identity-specific, limited to litigants, preserve substantial room for public advocacy on the merits, and offer a structured mechanism for necessary disclosures (e.g., NDAs for investigators/experts).
Potential fault lines: The dissent signals continued controversy over whether such orders should be treated as injunctions for interlocutory appeal, and future panels may face pressure to more sharply define when a “protective order” crosses the injunction threshold.

Complex Concepts Simplified

Prior restraint: A rule that forbids speech before it happens (often backed by contempt). Courts treat this as the most disfavored form of speech restriction.
Content-based restriction: A speech rule that depends on what you are saying (here: speech that identifies the Does). Content-based rules generally trigger strict scrutiny.
Strict scrutiny: The government (or the court order) must serve a compelling interest and use the least restrictive means (narrow tailoring).
Seattle Times discovery rule: A more forgiving standard applies when a court restricts dissemination of information obtained only through compelled discovery; it does not apply to information known independently.
§ 1292(a)(1) interlocutory appeal: A statutory pathway to appeal certain injunction-related orders immediately, before the whole case ends.
Collateral order doctrine: A narrow judge-made exception allowing immediate appeal of a small class of orders that would be effectively unreviewable after final judgment.
Vagueness: Due process requires laws/orders to give fair notice of what is prohibited and to avoid standards that invite arbitrary enforcement—especially where speech is chilled.

Conclusion

Baby Doe v. Joshua Mast establishes two practical rules in the Fourth Circuit. First, a protective order that restrains litigants’ out-of-court speech to the world can function as an appealable injunction under § 1292(a)(1). Second, while such an order is a content-based prior restraint when it limits dissemination of identity information known outside discovery, it may still survive strict scrutiny in the exceptional national-security context—particularly where disclosure would endanger perceived U.S. collaborators and erode the credibility of confidentiality assurances essential to U.S. foreign operations. The decision simultaneously warns district courts that pseudonymity is not a First Amendment blank check: anonymity in the caption and secrecy in the public sphere require distinct justifications.
