render the power of attorney given by the deceased to 
the plaintiff irrevocable.  
Therefore, in order for a power of attorney to be 
irrevocable,  the  agent  must  provide  valuable 
consideration to the principal under Section 6 of the 
Powers  of  Attorney  Act  1949.  Nevertheless,  this  is 
not  the  position  under  Section  7  of  the  Powers  of 
Attorney  Act  1949  as  under  the  Section,  valuable 
consideration is merely an option. Under the Section, 
the irrevocability is also only for a fixed time, where 
once  the  period  of  irrevocability  has  expired,  the 
power  continues  as  a  revocable  power  of  attorney. 
What  this  means  is  that  the  irrevocable  powers  of 
attorney  can  be  given  without  any  valuable 
consideration at all from the agent but the operation 
of the irrevocability is limited to a certain time frame 
only. It can be revoked by the principal without the 
consent  of  the  agent  once  the  irrevocability  period 
expires.  The  Law  Commission  for  England  and 
Wales in their Working Paper on Powers of Attorney 
(Working  Paper  No  11,  June  1967)  (“the  Law 
Commission”)  in  reviewing  the  amendment  to 
Section 126 and Section 127 of the United Kingdom 
Law of Property Act 1925 (similar to Sections 6 and 
7)stated  that  where  the  power  was  not  given  for 
valuable consideration, the irrevocability was merely 
a conveyancing device to protect a purchaser from the 
donee.  The  Law  Commission  in  the  process  of 
deliberation stated that it should be redrafted to make 
it clear that the powers of attorney granted by way of 
security could be made irrevocable in the truest and 
fullest sense either indefinitely or for a period; and in 
other cases, no question of irrevocability would arise 
as between  donor and  donee, but in  the  interests of 
conveyancing if a power of attorney is expressed to 
last for a fixed period not exceeding one year, those 
having  dealing  with  the  donee  during  that  period 
should be  entitled  to assume that the power has not 
been revoked (Charles Lim Aeng Cheng et al., 2009). 
3.3.2  Donee 
Section  6(1)(c):  In  Relation  to  Interest  of 
Purchaser. 
In Tai Swee Kian v Tay Boo Thiah @ 
Tai Boo Ting & Ors (MLJU 1013, 2011) the donor 
granted an irrevocable power of attorney to the donee 
to  sell  shares  of  donor  in  several  companies.  The 
power  of  attorney  specified  that  it  was  given  for 
valuable  consideration.  The  donor  then  sold  the 
shares specified under the power of attorney to third 
party.  The  donee  argued  that  under  the  power  of 
attorney,  he  had  the  right  to  sell  the  said  shares. 
Hence, the sale transaction between the donor and the 
third  party  was  void  as  it  was  entered  into 
notwithstanding  the  existence  of  the  power  of 
attorney and without the concurrence of the Plaintiff 
as  the  donor.  The  High  Court  analysed  Section 
6(1)(c), "(1) If a power of attorney, given for valuable 
consideration, is in the instrument creating the power 
expressed to be irrevocable, then, in favour of a 
purchaser -neither the donee of the power, nor the 
purchaser, shall at any time be prejudicially affected 
by notice of anything done by the donor of the power, 
without the concurrence of the donee of the power, or 
of the death, marriage, mental disorder, unsoundness 
of mind, or bankruptcy of the donor of the power.", 
and  stated  that  the  section  appears  to  be  aimed  at 
according  protection  to  a  purchaser  who  has 
purchased  or  obtained  property  pursuant  to  an 
irrevocable  power  of  attorney  given  for  valuable 
consideration. This means that if the Plaintiff, as the 
donee having the power of sale of the subject shares, 
had in fact sold the same to a third party, and then that 
sale having been effected pursuant to an irrevocable 
power  of  attorney  for  valuable  consideration,  it 
cannot  be  set  aside  or  affected  by  any  subsequent 
purported sale by the donor without the consent of the 
donee. In  other words,  the  equity of  the  third party 
would prevail over any purported sale by the donor 
without the express consent of the donee. However, 
in this case, the donee as Plaintiff did not, and has not, 
since the grant of the power of attorney exercised the 
power of sale under the power of attorney. In other 
words,  the  Plaintiff  as  the  donor  has  not  sold  the 
subject shares to any third party. There was nothing 
in the power of  attorney that prohibits the principal 
from conducting a sale  of the subject shares too, as 
the power of attorney is not drafted so as to divest the 
donor  completely  of  the  power  to  sell  the  subject 
shares.  Section  6(1)(c)  does  not  prescribe  that  the 
effect of  an irrevocable power of attorney given for 
valuable  consideration  has  the  effect  of  divesting 
completely  the  right  of  the  donor  to  deal  with  the 
subject  property  in  any  way.  What  the  section 
prescribes is that when a power of attorney has been 
exercised and a  third party has  acquired the subject 
property, such a transaction will not be vitiated by any 
act  of  the  donor  purporting  to  sell  the  property 
without the consent of the donee. In this case, there 
has been no exercise of the right of sale by the donee, 
thus section 6(1)(c) does not come into play.  
Thus, it can be seen that the irrevocable power of 
attorney relates to the purchaser, namely if the donee 
has  sold  to  a  purchaser  the  said  shares,  then  the 
interest of the donee is protected, so as the interest of 
the purchaser from him. But in  this case, the donee 
has not exercised the power and the donor at the same 
time did not expressly state that only the donee has
