The Superior Court has rejected an attempt by a union carpenter to hold three companies liable for asbestos-related injuries he allegedly sustained while working for an independent contractor at the firms’ Delaware facilities.

In a 29-page opinion, Judge Vivian L. Medinilla on April 18 said that Delmarva Power & Light Co., Getty and Sunoco did not owe plaintiff Werner Rath a duty of care stemming from his alleged exposure to the harmful substance while working alongside other tradesmen during his 27-year career with contractor Catalytic Inc., which was hired to perform work at the companies’ facilities in Delaware City and Claymont.
