Defendants’ evidence on an Anti-SLAPP motion did not establish that plaintiff had discovered its claim more than three years before it sued for fraud. The evidence at most showed that the plaintiff suspected and with diligent internet searches might have found that some of the facts stated in defendant’s letter were untrue, but that would not have shown plaintiff that the letter’s author knew or had reason to know his statements were false. And, indeed, the defendant, who had access to the same information he said was available to plaintiff, claimed that despite that knowledge, he had not known his statements were false. Hence, the fraud claim was not surely discovered at that point.
