feature in deciding whether a contravention has occurred. Is it a correct construction of the section which entails this consequence, that a man, being ordered to go along a haulage road on the assurance of his superior that it is lawful, does SO at penalty of discharge if he disobeys, and yet, being injured while SO doing, forfeits all claim to compensation because the road being in fact obstructed, or the rate of haulage being in fact 4 miles instead of 3 miles an hour, or the gradient of the road being in fact for more than 100 yards 1 in 11 instead of 1 in 12, his accident did not arise out of his employment ? If it were necessary to determine this point now, we should have great hesitation in holding that a miner can be said to contravene the section when, without disregarding any other requirement of the Act, he has fair reason to believe and does believe from a superior that the factors of exception exist. Until the contrary is shown, the fact that a superior official directs or authorizes a workman to walk along a haulage road should be taken to be an assurance that the conditions are such as to make it lawful. In such case it may be that the workman, not knowing otherwise, does not, and the employer or his agents do, contravene the section.
But this case, we think, may be decided on a very clear ground, which involves dealing with the appellant's two points (apart from the construction of par. (b) ) in the order in which we have stated them.
As to the first point, namely, whether the evidence sustains the finding, it is always to be remembered that the only right of appeal is on a question of law. In Highley's Case 1 Lord Haldane said
A Court of appeal ought not to review " the finding unless it is clear either that there was no evidence to support it, or that the finding was on the face of it erroneous in law." In this case, as in Herbert's Case 2, the finding is in terms that do not ex facie disclose any error in law. It is undeniable, and indeed undenied, that in direct examination the respondent gave evidence which, taken by itself, would entitle the arbitrator to find that the respon- dent went along the haulage road in obedience to superior direction. His fellow-workman, Goss, whom he was directed to find, was some- where, not definitely known, and the evidence in chief left it open
