in his serious and permanent disablement, but as he was not doing
any part of his duty at the time, his act cannot be deemed to
arise out of and in the course of his employment within the
meaning of sec. 7 (2) of the Workers' Compensation Act 1926-1929.
Tt is not a question of the applicant doing his proper job in a
wrong or prohibited way. as in Victoria Spinning Co. (Rochdale)
Ttd. v. Matthews (1), but of his voluntarily leaving his proper job
and doing something hazardous outside the scope of his employment,
and it was out of this unnecessary peril that the injury arose. There-
fore the negativing of the contravention of the prohibition contained
in rule 21, supra, as contemplated by sec. 7 (2), could not make the
injury one which could be deemed to arise out of and in the course
of the employment. The material cause of the applicant's injury
was not that he committed a breach of a prohibition in the execution
of duty when attempting to jump or ride on the locomotive, or that
he failed to obtain permission to ride on the engine, but that apart
from any prohibition he - instead of continuing in the course of his
employment on foot - of his own volition deviated from that course
and for purposes unconnected with his employer's business was
attempting to jump or ride on the moving locomotive. By so doing
he took himself away from his duties and needlessly put himself in
a place of obvious danger, and, unfortunately for him, the danger
materialized. In Matthews' Case (1), which was decided by the House
of Lords in July 1936, Lord Russell of Killowen, after referring to Wil-
sons & Clyde Coal Co. Ltd. v. M'Ferrin and Kerr or M'Aulay v. James
Dunlop & Co. Ltd. (2), said: * The different treatment of the cases
of the two men M'Ferrin and M'Aulay establishes, I think, the pro-
position. that if a workman at the time of the accident is doing
something which is not his job at all and in doing that job contra-
venes a regulation or order to which those whose job it is are subject
(as distinguished from the case of a workman whose job is subject
to a regulation or order which he contravenes while doing his job)
he is not within the provisions of sub-sec. 2, and the employer is
not liable to pay compensation. The matter was fully discussed
