If the judge presiding at the trial of an indictment of murder is
of opinion that the evidence discloses no matter capable of forming
provocation, or that the matter alleged by the prisoner as provoca-
tion is not capable of doing so, it is, of course, proper for him to
direct the jury to that effect. But, under the code as at common
law, it remains within the power of the jury to find a verdict of
manslaughter, even although it means disregarding the direction.
To tell the jury that they have not such a power is to state what
is not correct in law and a prisoner is entitled to complain in a Court
of Criminal Appeal of such a direction. There is all the difference
between such a direction and a direction that the evidence given
upon a trial for murder does not support a verdict of manslaughter.
If a judge is of opinion that because such a verdict implies findings
of fact that are not reasonably open the jury ought not to return it,
he may so direct them without necessarily usurping the functions
of the jury, and, if his opinion is correct in law, the verdict may
stand. Lawyers have no difficulty in apprehending the distinction
between, on the one hand, the impropriety of finding without evidence
facts amounting to manslaughter, and, on the other hand, the exist-
ence of a right to return a verdict of manslaughter although it be
a wrong verdict. But it is easy to believe that a jury would not
make the distinction and would treat a direction that they ought
not to find manslaughter as meaning that they had not power to
do so, unless it was very clearly expressed. Yet the jury must not
be led to understand that to find a verdict of manslaughter is actually
beyond their power. Further, upon the question whether a finding
of manslaughter on the ground of provocation would in a given case
be unreasonable, the ruling of the House of Lords in Woolmington's
Case (2) has, of course, an important bearing. For it may be open
to entertain a reasonable doubt of provocation although it would
be unreasonable to find affirmatively that provocation existed and
