Minister - an event which has probably not happened when the
member of the crew is absent from the muster. Inclusion in the
other classes depends upon questions of existing fact. But, while
the whole object of the proviso in par. (/) is to deal with absent
persons as to whom the actual truth is not certainly known, the
result of the construction contended for by the appellant would
be that it would fail in its operation, except as to the very limited
classes of persons specified in paragraphs (c) to (g). Itis, however,
evident that par. (/c) is intended to meet the case of every member of
the crew of a ship who is absent from muster. Moreover, if the
construction contended for is adopted, the provisions of par. (k)
would be to a great extent nugatory. For if the member of the
crew were found, the necessity for the opinion of the officer would
cease to exist, since the dictation test could be applied to him,
unless the time for applying it had gone by. It was contended
that the rule of evidence laid down by this paragraph applies
only to a prosecution against the prohibited immigrant himself,
but for the reasons just given they would, if applied for that
purpose only, be almost, if not entirely, superfluous. It is, in our
opinion, clear that the rule is laid down for the purpose of see. 9,
and not merely for the purposes of a prosecution against the man
himself. It is plain, therefore, that the main object of the
provisions in par. (), which is to prevent members of a ship's
crew from entering the Commonwealth as immigrants without
an opportunity of discovering whether they are or are not pro-
hibited immigrants, would be defeated if it were construed as not
extending to persons who are in fact unable to pass the dictation
test if it could be applied to them. Having regard to the condi-
tional form of the phrase incorporating the reference to class (),
and to the form of the definition of that class, the most natural
grammatical construction of the language of the legislature is
that the officer is to be of opinion that the person in question is
one who would, if called upon, fail to pass the dictation test. In
any case, the words are open to that construction, and, as apy
other construction would defeat the manifest intention of the
legislature, it ought, in our judgment, -to be adopted.
