criticized and it was pointed out that, if it were upheld, it could be
upheld only upon the finding of fact to which I have referred. There
is no evidence to support such a finding of fact in the present case.
In the first place, as I have already said, Henderson should be
regarded as having left his employer's premises when he reached
the railway platform. In the second place, there is no evidence
that any person to whom Henderson or the members of his gang
were responsible was aware that the practice of crossing the line at
this point existed. In the third place, a regulation had been made
under the Government Railways Act 1904-1926, sec. 3, prohibiting the
employees from walking on the railway line except in the execution
of their duty. It was proved that a copy of the regulations had been
supplied to Henderson and that he had duly acknowledged receipt
thereof - possibly unnecessarily, for under sec. 36 of the Interpretation
Act 1918 the regulation has the force of law. The phrase in the
regulation, "' execution of his duty", cannot be wider than (if, indeed,
it is as wide as) the phrase "in the course of his employment."
However this may be, if, as I have said, Henderson was not acting
in the course of his employment when he crossed the line, it cannot
be said that he was acting in the execution of his duty when he was
crossing the line. Accordingly he was breaking an express prohibi-
tion. An employer cannot protect himself against liability under
the Act by prohibiting certain actions and then winking at breaches
of the prohibition. But in the present case there is no evidence
that the employer was aware of the breaches or winked at any such
breaches. Further, the regulation in question has the force of law,
and it is not within the power of the Commissioner to make it ineffec-
tive in any respect by disregarding breaches of it. An employer
who makes rules for his factory but allows his employees to ignore
them in practice may quite well be held to have consented to the
course of conduct which is inconsistent with the pretended rules,
so that the result follows that an employee may be acting in the
course of his employment even though he is at the time breaking
one of the so-called rules. But this principle cannot be applied in
the case of a regulation which has statutory effect. A statutory
prohibition must be taken to be a genuine prohibition.
