(1) Where a power of
attorney given for valuable consideration (whether executed in or out of the
State) is in the instrument creating the power expressed to be irrevocable,
then, in favour of a purchaser —
(a) the
power shall not be revoked at any time, either by anything done by the donor
of the power without the concurrence of the donee, or by the death, mental
incapacity or bankruptcy of the donor; and
(b) any
act done at any time by the donee of the power in pursuance of the power is as
valid as if anything done by the donor without the concurrence of the donee,
or the death, mental incapacity or bankruptcy of the donor, had not been done
or had not happened; and
(c)
neither the donee of the power nor the purchaser shall at any time be
prejudicially affected by notice of anything done by the donor without the
concurrence of the donee, or of the death, mental incapacity, or bankruptcy of
the donor.
(2) This section
applies to powers of attorney created by instruments executed either before or
after the coming into operation of this Act.
