The ability to launch a preemptive strike against suits attacking speech or petitioning rights shouldn’t depend on which federal circuit has jurisdiction over the district court action. Yet that is how it stands right now when it comes to state law anti-SLAPP statutes deployed in federal diversity actions. At some point the United States Supreme Court will need to resolve the circuit split.
As it stands, the First, Fifth, and Ninth Circuits have allowed anti-SLAPP motions to be brought in federal court. The D.C. Circuit, however, has rejected them. The remainder of the circuits have not yet weighed in, leaving the district courts below them to decide the issue in the first instance. This could mean that a defendant is stripped of anti-SLAPP protection if an action is filed in federal court.
