What is the effect of a motion for fees and costs against defendants in an anti-SLAPP action?

The trial court denied the motion for fees and costs, finding the anti-SLAPP motion had not been clearly frivolous. The court noted the broad manner in which courts have construed the term public interest, and concluded that although the case relied upon by defendants, Wong v. Jing (2010) 189 Cal.App.4th 1354, 117 Cal.Rptr.3d 747, presented distinct issues, defendants' reliance on it was not frivolous. The court also found it not clear that defendants had brought the motion solely for delay. Plaintiffs appealed the denial of their motion for fees and costs.
