This decision states that an arbitrator may not consider an Anti-SLAPP motion to strike, but it finds that the arbitrator’s error in granting such a motion was harmless.  At the second stage of the Anti-SLAPP analysis, the arbitrator had to consider the merits of the defendant’s cross-complaint.  The arbitrator found that the litigation privilege (Civ. Code 47(b)) barred the cross-complaint.  Since the arbitrator could have made that ruling on a demurrer or similar attack on the pleadings over which the arbitrator clearly exercised appropriate jurisdiction, the cross-complainant could not show it was prejudiced by the arbitrator’s wielding the same power under a different, inappropriate statute.
