In People v. Persolve, (2013) 2013 DAR 10915, the Court of Appeal held that the litigation privilege is not a defense to a UCL action brought to enjoin business practices made unlawful by a statute more specific than Civil Code 47(b).  So, in this case, the People stated a good UCL claim against a debt collector for alleged unlawful business practices violating the FDCPA and Rosenthal FDCPA by collection letters and other conduct that otherwise would fall within the scope of the litigation privilege.
