is legally sufficient and supported by a sufficient prima facie showing of facts to sustain a favorable judgment if the evidence submitted by the plaintiff is credited.’ [Citation.] We went on to explain this test implicitly assumes the evidence on behalf of the plaintiff is admissible, ‘otherwise there would be nothing for the trier of fact to credit.’ [Citation.] In Roberts v. Los Angeles County Bar Assn, we held in order to demonstrate a probability of success a plaintiff ‘must adduce competent admissible evidence.’ [Citation.] Our Supreme Court has not spoken directly on this issue. However, in construing a statute which it described as ‘closely related’ to the SLAPP statute, the court held a plaintiff seeking punitive damages against certain health care providers must ‘demonstrate that he possesses a legally sufficient claim which is “substantiated,” that is, supported by competent, admissible evidence.’ [Citation.]”12
We went on to distinguish evidence which is substantively inadmissible from evidence which is only inadmissible because it fails to meet some collateral requirement for admissibility such as authentication. We observed:
“[T]he proper view of ‘admissible evidence’ for purposes of the SLAPP statute is evidence which, by its nature, is capable of being admitted at trial, i.e., evidence which is competent, relevant and not barred by a substantive rule. Courts have thus excluded evidence which would be barred at trial by the hearsay rule, [citation] or because it is speculative, not based on personal knowledge or consists of impermissible opinion testimony. [Citation.] This type of evidence cannot be used by the plaintiff to establish a probability of success on the merits because it could never be introduced at trial. On a SLAPP motion ‘[a]n assessment of the probability of prevailing on the claim looks to trial, and the evidence that will be presented at that time.’ [Citation.]”13
At first it would appear that under our decisions in Fashion 21 and Wilcox v. Superior Court, we should hold Gallagher failed to establish a probability of success on the merits of his slander cause of action. His probability of success depends at least in part on evidence which suffers from an incurable substantive defect—violation of the hearsay rule—and therefore “could never be introduced at trial.”14 Furthermore, in Wilcox we rejected the argument the plaintiff can satisfy its burden of proof merely by demonstrating
