SAN FRANCISCO — The head of Sedgwick’s cybersecurity practice can’t use California’s anti-SLAPP statute to fend off a lawsuit over a brawl with his neighbor, a state appeals court ruled on Wednesday.

Sedgwick partner John Stephens, who chairs the firm’s cybersecurity and privacy practice group in Los Angeles, was sued in August 2012 for defamation and other alleged injuries after distributing a cellphone video of his fight with neighbor Yasser Abuemeira and describing it as a hate crime.
