The court sought to focus on major issues confronting workers' compensation law, including the concepts of "light duty," the existence of the "coming and going rule," concerns over what risks are incidental to employment, the problem of the employee who is perceived to be working for multiple employers simultaneously, and other major issues such as [the "Fireman's Rule," the Falcon Doctrine, the Second Injury Fund, pension offsets, third party matters, medical treatment, and] what remedies are available to the employer where benefits appear to have been overpaid.
