remoteness, mitigation, intervening acts or
events, and contributory negligence with
respect to damages both in tort and, more
recently, for breach of contract (ibid). It
may be anticipated with some confidence that
similar questions to those which have given
rise to such doctrines will fall for
consideration in due course in proceedings for
relief under sec. 82. The ultimate test under
sec. 82 185 likely to be one of causation.
There is no present need to seek to elaborate
upon that observation beyond commenting that
there seems no reason to doubt that, in
general, loss or damage may not necessarily be
irrecoverable because its immediate cause is
not the contravention complained of; for
example, if it is some action reasonably taken
by the applicant in the circumstances in which
he finds himself in consequence of the
contravention, including such action taken in
an attempt to mitigate loss or damage.
Reasonableness 1s a question of fact and I
have, for the purposes of this case, proceeded
on the footing that, while reasonableness is
to be determined in all the circumstances
including the interests of the respondent as
well as the applicant, the standard required
of the applicant is not high and must be
assessed by reference to the circumstances at
the time not as they appeared with the
advantage of hindsight, and that the applicant
is not required to risk his money too far;
neither steps which prove to have been
mistakenly taken nor the fact that other
measures would have proved less burdensome to
a respondent necessarily mean a loss is not
recoverable. Conversely, there seems no
reason to doubt that, in general, it will be
open to a respondent not merely to contest the
elements of an applicant's claim, including
the reasonableness of any action taken by the
applicant, but to set up a positive case that
the applicant ought have mitigated the loss or
damage by other steps asserted to have been
reasonably open. Again speaking only
generally, it seems likely that the onus of
proof of a particular issue, including
reasonableness of conduct, will depend upon
