Ninth Circuit Ruling Will Force Online Platforms That Host User Speech to Fight Lengthy and Costly Lawsuits Before They Are Dismissed Under Section 230

A federal appeals court just made it harder for online services, big and small, to get lawsuits over user speech dismissed early. In California v. Meta, a Ninth Circuit three-judge panel held that the lower court’s denial of Section 230 immunity to Meta is not immediately appealable. The misguided ruling has the potential to have widespread impact and to threaten the free speech of all internet users.

The ruling is bigger than a loss for Meta, which has the resources to defend itself against these lawsuits. The court’s ruling signals that all online services (and internet users) that host others’ speech—including those without Meta’s deep pockets—must bear the burden and expense of fighting lawsuits that Section 230 ultimately precludes. This will have real consequences, incentivizing online services to take down users’ speech in response to spurious legal threats, filter speech preemptively, or simply stop offering a place for people to speak online. So even though some may think that Meta is not a sympathetic company, the ruling should raise concerns for anyone who cares about an open and free internet.

Immunities from Suit Advance Important Public Interests

A little procedural background is necessary to understand the implications of the Ninth Circuit’s ruling.

Meta had moved to dismiss a group of social media addiction cases brought by state attorneys general, school districts, and local governments. Meta argued that Section 230(c)(1) immunity applies because the plaintiffs’ claims, framed as seeking to hold Meta liable for allegedly harmful platform features, really seek to hold the company liable for publishing decisions related to third-party content. Section 230 is one of the most important laws supporting online free speech, because its protections for online services enable them to distribute users’ speech at an unprecedented scale.

The district court ruled that Section 230 does not apply to certain features (and does apply to others) and so denied the motion to dismiss on the claims related to those features. Meta immediately appealed invoking appellate jurisdiction under 28 U.S.C. § 1291, but the question before the Ninth Circuit was whether the appeal was legally appropriate.

Under Section 1291, U.S. circuit courts generally only have jurisdiction to hear appeals of “final decisions” from the district courts. Final decisions are trial court orders ending a case, or come after a trial on the merits. Section 230 appellate cases often arise from a district court’s grant of a defendant platform’s motion to dismiss the plaintiff’s case based on Section 230. Typically, a district court’s denial of a defendant’s motion to dismiss is not a final order—it simply means that the case may continue to discovery and summary judgment or trial, after which time an appeal would be appropriate.

However, federal law allows for “interlocutory appeals,” which are appeals of orders that do not end a case but nonetheless are allowed because they involve important legal issues. For example, there is an exception to Section 1291 called the “collateral order doctrine”—at issue in this case—allowing for immediate appeal if, as the Ninth Circuit explained here, “holding a trial would imperil a substantial public interest.”

Inherent in the collateral order doctrine is the consideration of whether an immunity like Section 230 provides mere “immunity from liability” or a more robust “immunity from suit.”

An immunity from liability does not require an immediate appeal and so demands that Section 1291’s final order rule be followed. That’s because waiting until the end of a case before an appellate court can consider the trial court’s denial of immunity does not prejudice the defendant. The appellate court may overturn the trial court and grant the immunity, and thus the defendant’s right to be immune from liability would be vindicated on appeal.

Immunity from suit is different. It means that the public interest demands that a defendant be able to get out of a case as early as possible and avoid having to litigate the case to the end. The U.S. Supreme Court has held, for example, that qualified immunity is such an immunity, and that a district court’s denial of qualified immunity for a government official is immediately appealable under Section 1291, notwithstanding the lack of a final order. The idea is that the public interest is served when government officials are free to act without fear of consequences when
