What is the test for an anti-SLAPP motion?

"A court evaluates an anti-SLAPP motion in two steps. 'Initially, the moving defendant bears the burden of establishing that the challenged allegations or claims "aris[e] from" protected activity in which the defendant has engaged. [Citations.] If the defendant carries its burden, the plaintiff must then demonstrate its claims have at least "minimal merit."' [Citation.] If the plaintiff fails to meet that burden, the court will strike the claim." (Wilson v. Cable News Network, Inc., supra, 7 Cal.5th at p. 884.)
