Our advice is that, in cases where there seems doubt whether an employee comes within the scope of the Act, the small premium to cover insurance should be paid willingly, at any rate until legal proceedings under the Act have led to certainty as to the interpretation of its provisions. It will be open to any employee who can find a solicitor to assist him to bring an action against his employer for compensation under the Act. Although the employer may win the case he will have to meet his legal expenses unless he is Insurance carries such expenses. insured. The scheme is simple in its nature and should be comprehensible, we think, without any trouble. The Medical Insurance Committee has established an agency for insurance against risks arising under the new Workmen’s Compensation Act, the scheme also taking cognisance of all risks of the employer for compensation to his employees at common law, as well as the risks of fire, burglary, and accident to the insurer. The agency will allow a discount of 10 per cent. to the insurer upon his premiums save in the case of fire, and here the rebate is not offered by the Guardian Insurance Company ; but we understand that the principal
