Defamation plaintiffs’ need for requested information outweighed any impact on Doe defendants’ free speech right to tweet anonymously.

Plaintiff company and its CEO sued several unknown defendants who tweeted that plaintiff company encouraged domestic violence and misogyny and that the CEO visited prostitutes. The court allowed plaintiffs to serve subpoenas on Twitter to seek the identity of the unknown Twitter users. Twitter would not comply with the subpoenas unless and until the court ruled on whether the production of information would violate the users’ First Amendment rights.

The court ruled in favor of the plaintiffs and ordered Twitter to turn over identifying information about the unknown users. In reaching this decision, the court applied the Ninth Circuit analysis for unmasking anonymous internet speakers set out in Perry v. Schwarzenegger, 591 F.3d. 1126 (9th Cir. 2009). The court found that the requested discovery raised the possibility of “arguable first amendment infringement,” so it continued its analysis by weighing the balance between the aggrieved plaintiffs’ interests with the anonymous defendants’ free speech rights.

The Perry balancing test places a burden on the party seeking discovery to show that the information sought is rationally related to a compelling governmental interest and that the requested discovery is the least restrictive means of obtaining the desired information.

In this case, the court found that the subpoenas were narrowly tailored to plaintiffs’ need to uncover the identities of the anonymous defendants so that plaintiffs could serve process. It also found that the “nature” of defendants’ speech weighed in favor of enforcing the subpoena. The challenged speech went “beyond criticism into what appear[ed] to be pure defamation, ostensibly unrelated to normal corporate activity.”
