public significance. (Briggs, supra, at p. 1109.) And in a trio of opinions issued last year, we held that the plain language of the “arising from” prong encompasses any action based on protected speech or petitioning activity as defined in the statute (Navellier v. Sletten (2002) 29 Cal.4th 82, 89-95 [124 Cal.Rptr.2d 530, 52 P.3d 703] (Navellier)), rejecting proposals that we judicially engraft the statute with requirements that defendants moving thereunder also prove the suit was intended to chill their speech (Equilon, supra, 29 Cal.4th at p. 58) or actually had that effect (City of Cotati v. Cashman (2002) 29 Cal.4th 69, 75 [124 Cal.Rptr.2d 519, 52 P.3d 695]).
The Court of Appeal, in concluding that this malicious prosecution action falls within the anti-SLAPP statute’s “arising from” prong, adhered to our plain language approach. As we previously have observed, “plainly read, section 425.16 encompasses any cause of action against a person arising from any statement or writing made in, or in connection with an issue under consideration or review by, an official proceeding or body.” (Briggs, supra, 19 Cal.4th at p. 1113.) Consistently with that observation, the Court of Appeal held that this action, which is based on allegations that LaMarche and Brutzkus maliciously and without probable cause brought and maintained a cross-complaint against Jarrow in the course of a civil lawsuit, is subject to anti-SLAPP scrutiny.
The Court of Appeal grounded its conclusion in the anti-SLAPP statute’s express definition of a “cause of action against a person arising from any act of that person in furtherance of the person’s right of petition or free speech under the United States or California Constitution in connection with a public issue.” (§ 425.16, subd. (b)(1).) That definition, which is found in subdivision (e) of the statute, places within section 425.16’s purview “any written . . . statement or writing made before a . . . judicial proceeding,” “any written . . . statement or writing made in connection with an issue under consideration or review by a . . . judicial body,” and “any other conduct in furtherance of the exercise of the constitutional right of petition.” (§ 425.16, subd. (e)(1), (2) & (4).) As the Court of Appeal noted, LaMarche was sued for filing a cross-complaint in the former municipal court and Brutzkus, her attorney, for written and oral statements he made while acting as an advocate for LaMarche in the municipal court action. Accordingly, the Court of Appeal reasoned, this action falls within the ambit of a “cause of action against a person arising from any act . . . in furtherance of the person’s right of petition” (§ 425.16, subd. (b)(1)), as statutorily defined.
As a plain language matter, the Court of Appeal unquestionably was correct. Indeed, the point is not disputed. Jarrow concedes that, by its terms, section 425.16 potentially may apply to every malicious prosecution action, because every such action arises from an underlying lawsuit, or petition to the
