Is a demand letter or demand letter protected under section 425.16 of the California Anti-SLAPP Act?

"'[A]lthough litigation may not have commenced, if a statement "concern[s] the subject of the dispute" and is made "in anticipation of litigation 'contemplated in good faith and under serious consideration'" [citation] then the statement may be petitioning activity protected by section 425.16.' [Citation.]" (Bailey v. Brewer (2011) 197 Cal.App.4th 781, 789-790.) Most anti-SLAPP cases involving prelitigation communications "concern demand letters or other statements to adverse parties or potential adverse parties." (Neville v. Chudacoff (2008) 160 Cal.App.4th 1255, 1270.)
