While the law firm Stradley Ronon Stevens & Young is not a named defendant in eight civil lawsuits in which plaintiffs allege sexual abuse by Catholic priests, some of the complaints claim that the law firm assisted the Archdiocese of Philadelphia in efforts to conceal sexual misconduct by its clergy.

William R. Sasso, chairman of the firm, said in an interview that “the statements they made are nonsense and totally false,” and the firm will investigate if the statements are outside the privilege accorded to court filings.
