legislature may displace the rule and provide for
the exercise of such a power without any
opportunity being afforded the affected person to
oppose its exercise. However, if that is the
legislative intention it must be made unambiguously
clear. In the event that the legislation does not
clearly preclude such a course, the court will. as
it were, itself supplement the legislation by
insisting that the statutory powers are to be
exercised only after an appropriate opportunity has
been afforded the subject whose person or property
1s the subject of the exercise of the statutory
power. But, if the legislation has made provision
for that opportunity to be aqiven to the subject
before his person or property is so affected, the
court will not be warranted in supplementing the
legislation, even if the legislative provision is
not as full and complete as the court might think
appropriate. Thus, if the legislature has
addressed itself to the question whether an
opportunity should be afforded the citizen to be
relevantly heard and has either made it clear that
no such opportunity is to be given or has, by its
legislation, decided what opportunity should be
afforded, the court, being bound by the legislation
as much as 15 the citizen, has no warrant to vary
the legislative scheme. But, if it appears to the
court that the legislature has not addressed itself
to the appropriate question, the court in the
protection of the citizen and in the provision of
natural justice may declare that statutory action
affecting the person or property of the citizen
without affording the citizen an opportunity to he
heard before he or his property is affected is
ineffective. The court will approach the
construction of the statute with a presumption that
the legislature does not intend to deny natural
justice to the citizen. Where the legislation is
silent on the matter, the court may presume that
the legislature has left it to the courts to
prescribe and enforce the appropriate procedure to
ensure natural justice. In my opinion, this
statement of relevant principal is in accord with
the authorities, including particularly the case of
Wiseman v. Borneman £19717 A.C. 297."
