Now, accepting the findings of the learned commissioner as against both Mitchell and those in charge of the ship, there remains a difficult question with regard to the law. Upon the whole, I think that the defendants are right on the question of law. It seems to me, in dealing with a section which, as regards this case, is one giving a right to indemnity, that, if I can adopt any reasonable construction which will prevent the result of a man getting an indemnity in respect of damage to the production of which he has himself materially contributed, I ought to adopt that construction. The plaintiffs have been found by the learned commissioner to have been one effective cause, as Mitchell was another, of this accident. They claim to be indemnified for what they have paid by way of compensation under the Workmen's Compensation Act, 1906, in respect of the accident. It seems to me that nobody who helped to pass this Act of Parliament, which makes an employer liable apart from all questions of negligence to make compensation in respect of an accident to a workman arising out of and in the course of his employment, could have intended by this section that, though the employer could have been sued, if not at common law, at any rate under the Employers' Liability Act, 1880, as being through his servants to blame for the accident, he should be able to go to another person whose servant has been guilty of negligence which in common with that of his own servants caused the accident, and demand an indemnity. There is nothing in the Act, as it appears to me, to prevent my taking this view. If necessary for this purpose, I think I should say that it is not unreasonable, having regard to the consequences of any other interpretation, to read the words "creating a legal liability in some person other than the employer" as meaning a legal liability which, as between the employer and the third person, is the sole legal liability. It has, I think, been pointed out by both the other members of the Court that a fair inference from the provisions of sub-s. 2 with regard to the determination of any question as to the right to and amount of the indemnity is that it includes the consideration of the question whether a party claiming indemnity is not disentitled to claim indemnity by reason of his being equally liable for the accident, just as in the case put by the learned commissioner of a contract by which the right to indemnity is excluded. I think on the whole that the section should be treated as applying only to cases in which the employer is liable only for compensation under the Act, and not as applying to cases where the employer himself is, through his own or his servants' negligence, responsible outside the Act jointly with the person from whom he claims indemnity, as having to some extent contributed to the injury to the workman who has been compensated.
