Anti-SLAPP denials are appealable as collateral orders, 9th Circuit says

Tim Kowal     September 26, 2023

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.

"Good people do not need laws to tell them to act responsibly, while bad people will find a way around the laws."

"It may be that the court is thought to be excessively legalistic. I should be sorry to think that it is anything else."

"At common law, barratry was 'the offense of frequently exciting and stirring up suits and quarrels' (4 Blackstone, Commentaries 134) and was punished as a misdemeanor."

Rubin v. Green (1993) 4 Cal.4th 1187

"Counsel on the firing line in an actual trial must be prepared for surprises, including requests for amendments of pleading. They cannot ask that a judgment afterwards obtained be set aside merely because their equilibrium was slightly disturbed by an unexpected motion."

Posz v. Burchell (1962) 209 Cal.App.2d 324, 334

"God made the angels to show Him splendor, … Man He made to serve Him wittily, in the tangle of his mind."

Show neither partiality to the weak nor deference to the mighty, but judge your fellow men justly.


"Upon putting laws into writing, they became even harder to change than before, and a hundred legal fictions rose to reconcile them with reality."

— Will Durant

"Moot points have to be settled somehow, once they get thrust upon us. If an assertion cannot be proved, then it must be settled some other way, and nearly all of these ways are unfair to somebody."

—T.H. White, The Once and Future King

"So far as the beginnings of law had theories, the first theory of liability was in terms of a duty to buy off the vengeance of him to whom an injury had been done whether by oneself or by something in one's power. The idea is put strikingly in the Anglo-Saxon legal proverb, 'Buy spear from side or bear it,' that is, buy off the feud or fight it out."

— Roscoe Pound, An Introduction to the Philosophy of Law

“It will be of little avail to the people, that the laws are made by men of their own choice, if the laws be so voluminous that they cannot be read, or so incoherent that they cannot be understood; if they be repealed or revised before they are promulgated, or undergo such incessant changes that no man, who knows what the law is today, can guess what it will be tomorrow. Law is defined to be a rule of action; but how can that be a rule, which is little known, and less fixed?”

— James Madison, Federalist 62
