The estate of the late Pennsylvania Superior Court Judge Robert C. Daniels has filed a lawsuit against securities and class-action attorney Sherrie R. Savett and two other defendants over Daniels’ fatal fall at an engagement party in Savett’s home, according to a complaint filed Tuesday.

The defendants are Savett, managing shareholder with Berger & Montague and chair of the firm’s securities fraud group and whistleblower, qui tam and False Claims Act group; the caterer for the party, Betty the Caterer; and catering staffing company Ellsworth Scott & Staff, the complaint said.
