Numerous authorities were cited to us, but there is really no
room for controversy as to the law. The defendant relies on sec,
20 of the Government Railways Act 1904 (3 Edw. VII. No. 23),
By that Act the Commissioner for Railways is constituted a
corporation sole, and is charged with the management, mainten-
ance and control of the government railways. Section 20 enacts
that the Commissioner "may use on any railway locomotive
engines consuming any kind of fuel." The fuel in use when the
damage complained of was occasioned consisted of a mixture of
equal proportions of Collie coal, (the product of coal mines in the
south western part of the State of Western Australia), and
Newcastle coal (from New South Wales). It is conceded that
this mixture was less likely to emit sparks than Collie coal alone.
The respondent contends that authority to use "any kind of fuel"
includes authority to use Collie coal as fuel, either alone or
mixed with other coal, and that, the use being lawful, and there
being no negligence in the manner of the use, an action will not
lie. The appellant contends that the words "consuming any
kind of fuel" are a mere description of the kinds of locomotives
that may be used, and do not coffer any authority which would
not follow from the mere permission to use locomotives, and,
further, that if they do authorize the use of any kind of fuel, still
the Commissioner may be guilty of negligence in the choice or
selection of the kind of fuel which he will use, so that, if he
selects a kind which is more likely to emit sparks than another
which he might reasonably have used, he is guilty of negligence,
