"But once it is realized that the power authorizes
prohibition, complete or partial, conditional or
unconditional, what reason is there for denying
that the condition may be the consent, or licence,
or approval of a person or a body? The answer that
there is none was given by the Divisional Court and
approved by the Court of Appeal in Williams v.
Weston-super-Mare Urban District Council ((1907) 98
L.T. 537; (1910) 103 L.T. 9); and we respectfully
agree. The supposition or suggestion that the
conditions or circumstances should be defined in
which the consent, licence, or approval must be
given can rest only upon some justification other
than the words in which the power is conferred.
From the passage in the judgment of Higgins J.
in Barry's Case (at p.208) already referred to, it
appears that he considered that such a
justification in the case of municipal councils
might be found in the view that the procedure
prescribed for making by-laws impliedly forbids the
choice of the council as the repository of any
discretion upon which the operation of the by-law
may be conditioned. But this view rests upon an
implication which the canons of interpretation
scarcely warrant. The municipal council must
conform to the prescribed procedure in formulating
a prohibition, conditional or unconditional; but
why does this requirement import any limitation in
the exercise under the by-law of powers or
authorities upon which it, in terms, makes the
extent of its prohibition depend?"
