Background
Thousands of lawsuits consolidated in multidistrict litigation allege that social-media platforms encourage addictive behavior, fail to verify users’ ages, enable adolescents to bypass parental controls, and inadequately protect users from harmful content. The district court organized the litigation into tracks encompassing personal-injury plaintiffs, state attorneys general, school districts, local governments, and claims against Meta CEO Mark Zuckerberg.
Meta and the TikTok-related entities sought dismissal of various claims under Section 230 of the Communications Decency Act. The district court ruled that Section 230 barred some claims insofar as they targeted the platforms’ role as publishers of third-party content, but allowed other claims to proceed. Meta and TikTok appealed without obtaining certification for an interlocutory appeal under 28 U.S.C. § 1292(b), contending that the partial denial of their Section 230 defense was immediately appealable under the collateral order doctrine. The plaintiffs filed protective conditional cross-appeals.
The Court’s Holding
The Ninth Circuit dismissed the platforms’ appeals and the plaintiffs’ conditional cross-appeals for lack of appellate jurisdiction. It held that Section 230 provides a defense to liability, not immunity from suit. Because an erroneous denial of that defense can be reviewed after final judgment, the district court’s interlocutory rulings were not effectively unreviewable later and therefore did not qualify as collateral orders under 28 U.S.C. § 1291.
The court also concluded that the rulings failed the collateral order doctrine’s other requirements. They did not conclusively resolve the Section 230 issues because the district court allowed certain claims to proceed “for now” and indicated that it might revisit the defense as the litigation developed. Nor were the issues completely separate from the merits, because applying Section 230 requires examining each claim’s factual allegations and determining whether its theory of liability treats the defendant as the publisher or speaker of third-party content.
Key Takeaways
- Section 230 supplies a defense against liability rather than an immunity from being sued.
- A district court’s interlocutory denial of a Section 230 defense is not immediately appealable under the collateral order doctrine.
- Prior Ninth Circuit opinions using “immunity from suit” terminology did not decide the jurisdictional question and therefore did not establish contrary precedent.
- The parties may obtain review of the Section 230 rulings after final judgment, subject to ordinary appellate requirements.
Why It Matters
The decision limits social-media companies’ ability to halt ongoing litigation through immediate appeals of adverse Section 230 rulings. Unless another route to interlocutory review is available, platforms generally must continue litigating and wait for final judgment before challenging the denial of a Section 230 defense.
The opinion also clarifies that courts should not treat casual references to Section 230 “immunity” as establishing a right to avoid the burdens of suit. For appellate-jurisdiction purposes, the statute protects against certain forms of liability but does not expressly guarantee that trial will not occur.
