Mistake : an erroneous belief about something - may be mistake of law or a mistake of fact.
Sec.20 – where both parties are under
mistake as to matter of fact essential to the agreement – the agreement is
void.
Sec.20 will come into play when –
(1)
both the parties to an
agreement are mistaken;
(2)
their mistake is as to a matter
of fact;
(3)
the fact about which they are
mistaken is essential to the agreement.
Sec.21 – a
contract is not voidable because it was caused by mistake of law of the country. However, mistake as to law of a foreign
country is treated as mistake of fact and makes the contract void.
Sec.22 – a contract is not voidable merely
because it was caused by mistake of one party as to matter of fact.
Mistake
of law -
a) Mistake of law of the country – (ignorantia juris non excusat , i.e. ignorance of law is not excuse) –
contract cannot be avoided.
Example : A and
B enter into a contract - on the erroneous belief that a particular debt is
barred by the Indian Law of Limitation – contract is not voidable.
But where person
enters into a contract by making a mistake of law through inducement of another
(whether innocent or otherwise), the contract is voidable.
(b) Mistake
of law of a foreign country - treated as mistake of fact – contract is void.
Mistake of fact – may
be bilateral or unilateral.
Bilateral
Mistake – both the parties are mistaken as to a
matter of fact essential to the agreement – agreement is void.
1. The mistake
must be mutual.
Example – A
agreed to purchase B’s motor car lying in B’s garage – Unknown to both, the
garage and car destroyed by fire a day earlier – void agreement.
2. Mistake must
relate to matter of fact essential to the agreement – as to what facts are
essential to the agreement depends upon the nature of the promise in each
case.
Galloway Vs.
Galloway - man and woman entered
into separation agreement under which
man to pay weekly allowance to woman – both mistakenly believe themselves to
the lawfully married – Held, mutual mistake on a point of fact which was
material to the existence of agreement – void agreement.
However, an
erroneous view as to value of a thing which forms the subject matter of
agreement is not deemed as mistake of fact
Example – A buys
an old painting for Rs.5000 – mistakenly assumed it to be an antique – actually
it was new one and worth only Rs.500 – Mistake as to value of the subject
matter – not voidable.
Bilateral mistakes can be of following types –
1. Mistake as
to the subject matter – agreement is void
Example – A
agreed to buy B’s horse – unknown to both, the horse was dead at the time of
bargain – agreement is void.
Couturier Vs. Hastie – H
employed by C as del credere agent to sell C’s cargo of corn which was in transit
– H sold the cargo to a third person - Unknown to both, the corn became fermented in transit and
already sold by the master of the ship at an intermediate port – buyer
repudiated the contract and H was sued for the price (being del credere agent) – Held, as goods had
already been totally lost before the contract was made, the contract void ab initio - H not liable.
2. Mistake as
to identity of subject-matter – happens when one
party intends to deal in one thing and the other intends to deal in another.
Raffles Vs.
Wichelhaus – W agreed
to buy a cargo of Surat Cotton from R ‘to arrive ex-Peerless from Bombay’ - actually two ships by that name sailing
from Bombay, one in October and another in December – W meant the former while
R meant the latter – Held, mutual mistake and hence no contract.
Even if mistake caused
by negligence of third party – contract void.
Henkel Vs. Pape – A
inspected fifty rifles in B’s shop – Later, wired to B “send three rifles” – by
mistake of telegraph office, the message transmitted as “send the rifles” – B
sent fifty rifles – A accepted three rifles and sent back the rest – Held,
there was no contract on account of mutual mistake as to identity of subject
matter – however, A liable to pay for three rifles on basis of an implied
contract.
3. Mistake as
to quality of subject matter – if the subject
matter is qualitatively different from what the parties thought it to be –
agreement is void.
Nicholson & Venn Vs. Smith Marriot - table napkins sold at
auction - by description “with the crest of Charles I and authentic property of
that monarch” – actually napkins belonged to King George – Held, mistake as to
quality of the subject matter – agreement void.
4. Mistake as
to quantity of subject matter – if mutual mistake
as to quantity of subject matter – agreement void.
Cox Vs. Prentice – Silver
bar sold under a mistake as to its weight – Held agreement is void
5. Mistake as
to title of subject matter – if seller intends to
sell something which he is not entitled to sell – agreement is void.
Cooper Vs.
Phibbs - uncle had told his nephew, not intending to
misrepresent anything but being in fact in error, that he (uncle) was entitled
to a fishery – after uncle’s death, nephew entered into agreement with uncle’s
daughter to rent the fishery – actually fishery belonged to nephew himself –
Held the lease was void.
6. Mistake as
to price of subject matter – where mutual mistake
as to price – agreement is void.
Webster Vs. Cecil – W
offered to buy C’s property for £2000 – C declined – thereafter C offered to
sell the same property for £1250 - W
accepted the offer, knowing that this offer price was a mistake which should
have been for £2250 – Held, W knew that offer was a mistake – contract void.
7. Mistake as
to possibility of performance - impossibility may be due to
a)Physical
impossibility
Griffith Vs.
Brymer - contract for hiring of a
room for witnessing the coronation procession of King Edward VII – unknown to
the parties, the procession had already been cancelled – Held, the agreement
void for impossibility of performance.
b) Legal
impossibility – if subject matter of contract cannot be done as per law –
agreement is void.
Unilateral Mistake - Sec.22 – agreement not voidable merely
because it was caused by unilateral mistake as to matter of fact – however, it
can be allowed as defence where mistake brought about by other party’s
misrepresentation or fraud.
Smith Vs. Hughes – H wanted to buy old oats for his horses – S showed him sample of
oats which he had – W mistakenly thought that oats were old when they were
actually new – Held, though two minds were not ad idem as to age of the oats, they certainly were ad idem as to the sale and purchase of
them – H cannot avoid the contract.
Exceptions – In certain
cases, when unilateral mistake goes to the root of the agreement, agreement is
void.
1. Mistake as
to identity of person contracted with – if one
party represents himself to be some other person, there is mistake as to the
identity of the person contracted with.
Example – A
intends to contract with B – mistakes C to be B and enters into contract with
him (C) – no agreement if B was a material element of contract. Even in cases where A makes an offer to B, C
cannot give get any rights under the contract by accepting the offer – if he
does so, contract is void.
Boulton Vs.
Jones – B purchased goods from H – H owed debt to J
– J placed order on H – J accepted goods from B thinking that they were
supplied by H – B had supplied the same intending to set off his debt against H
– Mistaken identity of the acceptor – no contract. However, B can recover the goods from J under
quasi-contract.
Cundy Vs. Lindsay - Blenkarn ordered goods from Lindsay – signed
the offer letter in such a way that L believed it came from well-known firm of
Blenkiron & Co. – Held, L never intended to deal with Blenkarn, having
heard of him – no contract.
This exception
holds good only when identity of contracting party is important.
Said Vs. Butt – S wanted
to go to first night of play – B, the managing director of theatre, gave
instructions that ticket be not sold to S – because in past S had published
virulent (strong) criticism of its production – S got his friend to buy a
ticket – theatre manager refused admission to S – Held, no contract as theatre
never intended to contract with S.
Where the
identity of a party is immaterial to the contract – contract is not void –
attribute of a party does not affect the contract.
Philips Vs. Brooks – N
bought jewellery from a jeweller’s shop – presented himself as Sir George
Bullough – gave a cheque which bounced – jeweller sued for annulment
(cancellation) of contract - Held, jeweller contracted to sell and deliver
jewellery to person who came to his shop – here mistake not as to identity but
to attribute of the buyer – valid contract.
2. Mistake as
to nature of contract - if document signed under mistaken belief
that they are of different class and character altogether - void contract.
Foster Vs. Mackinnon – M,
an old man of poor sight, endorsed a bill of exchange – had mistakenly thought
it to be a guarantee – Held, the mind of the signer did not accompany the
signature – no contract.
