In DeOliveira v. Liberty Mut. Ins. Co., Nos. 17132, 17169, 2005 WL 975685 ( Conn. May 3, 2005), the Connecticut Supreme Court held that the exclusivity provision of the Workers Compensation Act barred a bad faith action against an insurer.

Antonio DeOliveira suffered a back injury on the job after lifting a heavy bag of materials. No one witnessed the accident, and he reported it to his supervisors the next day. He filed for workers compensation. His employer contested the claim that his injury arose in the course of his employment.
