is an injustice, either to the Crown or the individual taxpayer. But
I think that by the words " it shall be lawful" in that section it is
intended that his action is to be entirely voluntary. He is not to
be coerced into acting under sec. 70. The rights of the parties are
fixed otherwise. It is intended that he shall take a high position
in this matter and shall not claim for the Crown more than he sees
the Crown is entitled to, and he is not to allow any taxpayer to
escape payment of any amount which the law intends him to be
liable to pay. There is no reason why the Commissioner should
not in a proper case exercise his power merely because he is requested
to do so by a taxpayer. The Commissioner's action in such case is
none the less voluntary. But I would be unable to give sec. 70 the
interpretation suggested by counsel for the appellant and to stop
where he stops. I would be unable to say there is an obligation on
the Commissioner to hear every taxpayer who, having been assessed,
claims a reduction, and to listen to the evidence which might be
adduced in order to inform his mind, if the Legislature meant
that the Commissioner might do a palpable wrong immediately
afterwards by refusing to correct an error made manifest by the
inquiry. That would make the section itself so inconsistent and
unjust that I could not accept the interpretation. I could not go
so far as to say that there is an absolute duty to hear and determine
unless I could also say that, having heard and determined, there
was an absolute duty to order a refund. It is not like the cases cited
of discretionary powers after a necessary hearing, because there the
standard of right is the discretion of the tribunal, but here the
standard of right is the income tax law. Therefore I think that the
Commissioner is entrusted by the Legislature, notwithstanding the
normal fixation of the liability of the taxpayer by the assessment,
as it ultimately stands after appeal or abstention from appeal, to do
what is right to the Crown and the taxpayer as he may throughout
voluntarily determine, and I think that he is not to be driven into
this avenue of consideration against his will, any more than he can
be prevented from entering it if he so wills.
