The charge against the prisoner was laid under sec. 14 of the
Criminal Law Consolidation Act 1935 (S.A.). The section is a long
one, comprising four sub-sections, all of which should be considered
to obtain a full appreciation of its effect, but the words actually
creating the offence or offences are relatively few. They are as
follows : "* Any person who - (a) drives a motor vehicle in a culpably
negligent manner, or recklessly, or at a speed, or in a manner, which
is dangerous to the public ; and (b) by such negligence, recklessness,
or other conduct, causes the death of any person, shall be guilty of
amisdemeanour." Upona similar, but not quite identical, set of words
Cussen J., in Kane v. Dureau (1), made three observations which we
think are true of the South Australian provision. He said that there are
several offences specified - driving recklessly ; driving with (culpable)
negligence ; driving at a speed which is dangerous to the public ;
and driving in a manner which is dangerous to the public. Secondly,
he said that he was by no means satisfied that the words were
intended to be used in such a manner as to prevent any overlapping
of the various offences therein set out. Thirdly, he said that, with-
out giving any exhaustive definition of the word "recklessly," it
included an element which distinguished it from the other offences
specified, an element which he called indifference to consequences.
The chief fear of the Crown is that the judgment from which special
leave to appeal is sought imports this element into the other offences
mentioned in the clause. The correctness of such a reading of the
judgment may be doubted, but it seems better to say that, in our
opinion, indifference to consequences is not an essential element
either of driving in a culpably negligent manner, or of driving at
a speed which is dangerous to the public, or in a manner which is
dangerous to the public. The driver may have honestly believed
that he was driving very carefully, and yet may be guilty of driving
in a manner which is dangerous to the public. The jury is to
determine, not whether the accused was in fact, as a matter of
psychology, indifferent or not to the public safety, but whether he
has driven in a manner which was dangerous to the public. The
standard is an objective standard, " impersonal and universal, fixed
in relation to the safety of other users of the highway " (per Hewart
