Congress has not enacted an anti-SLAPP statute like the ones in many states, such as California, which prohibit “strategic lawsuits against public participation.” Anti-SLAPP motions protect defendants sued for defamation or the like. But again, there is no federal anti-SLAPP law providing for such a motion.
Still, that has proved no problem for the 9th Circuit, which has seen fit to apply state anti-SLAPP statutes.
But aren’t these state anti-SLAPP laws procedural mechanisms? And state procedural statutes don’t apply in federal court, right? Well, that’s true, says the 9th Circuit, if we were to admit that anti-SLAPP motions are procedural devices. But we don’t admit that. The anti-SLAPP statutes enshrine a substantive right, and we can enforce those substantive rights through the federal procedural statutes for motions to dismiss and motions for summary judgment.
If you’ve followed the 9th Circuit’s legal fiction thus far, surely you’ll indulge one more. So now you’ve had your anti-SLAPP motion denied by the district court, and you want to appeal. But an anti-SLAPP motion in district court is governed as some amalgam of a motion to dismiss and a motion for summary judgment, and denials of such motions are not appealable.
No matter, says the 9th Circuit in Martinez v. ZoomInfo Tech. Inc., No. 22-35305 (9th Cir. Sep. 21, 2023), because there is the collateral order doctrine. An order is appealable as a collateral order when they are “conclusive”, and resolve important questions “separate from the merits,” and are effectively unreviewable on appeal from a final judgment. But it is hard to see how an anti-SLAPP denial is “conclusive” (because Code of Civil Procedure section 425.16 expressly states that no ultimate facts in the case “shall be affected by th[e] determination” on the motion). And anti-SLAPP denials are not “separate from the merits” (again, section 425.16 expressly requires the plaintiff to establish a probability that it “will prevail on” its complaint).
But that is the rule in the 9th Circuit. Denials of anti-SLAPP motions are appealable as collateral orders.
Judge Bress has frequently raised these criticisms with his colleagues, such as in Salveson v. Kessler. Given the seriousness of his criticisms, and the circuit split on the issue, it strikes me as uncongenial of his colleagues to ignore them.
