Background
Thousands of lawsuits in multidistrict litigation alleged 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 covering personal-injury plaintiffs, state attorneys general, school districts and local governments, and other claimants.
Meta moved to dismiss claims on several grounds, including Section 230 of the Communications Decency Act. The district court held that Section 230 barred some claims insofar as they targeted Meta’s role as publisher of third-party content, but allowed other claims to proceed. Meta and the TikTok entities appealed those interlocutory rulings under the collateral order doctrine, while plaintiffs filed conditional cross-appeals.
The Court’s Holding
The Ninth Circuit dismissed the appeals and conditional cross-appeals for lack of appellate jurisdiction. It held that Section 230 supplies a defense to liability, not immunity from suit. Because a denial of that defense can be reviewed after final judgment, the district court’s orders were not effectively unreviewable later and therefore did not qualify as appealable collateral orders.
The orders also failed the collateral order doctrine’s other requirements. The district court had not conclusively resolved the Section 230 questions because it indicated that it could revisit them as the litigation developed. And the Section 230 analysis was not completely separate from the merits because it required claim-by-claim examination of the plaintiffs’ theories and factual allegations to determine whether they treated defendants as publishers or speakers of third-party content.
Key Takeaways
- Section 230 provides a defense to liability rather than immunity from being sued.
- An order denying a Section 230 defense ordinarily cannot be appealed immediately under the collateral order doctrine.
- Courts must examine each claim’s theory and factual context to determine whether Section 230 bars liability based on publishing third-party content.
Why It Matters
The decision prevents online platforms from obtaining an appeal as of right whenever a district court declines to dismiss claims under Section 230. Unless another route to interlocutory review is available, defendants must generally litigate to final judgment before challenging such rulings on appeal.
The Ninth Circuit also clarified that earlier opinions loosely describing Section 230 as “immunity from suit” did not decide the jurisdictional question and therefore did not establish a right to immediate appellate review.
