Described as "a confused and
difficult branch of law" by Lord
Atkin in Bell v Lever Brothers
1932.
There are four key areas to
consider: common, mutual,
unilateral, mistake as to the
nature of the documents.
Common Mistake
Both parties make the same
error relating to fundamental
fact.
Res Extincta: a
contract will be
void at common
law if the subject
matter is
non-existent.
Scott v Coulson: at the time of
entering a contract for life insurance,
both parties believed the person who's
life was to be insured was alive, when
he was in fact dead. Void for mistake.
Galloway v Galloway: a couple were
separating and believed they were married
when in fact they were not. Void for
common mistake when they realised their
marriage was a nullity.
Couturier v Hastie: a cargo of corn
was being shipped from the Med Sea
to England and the owner sold it to a
man in London. However, before it
was sold the goods had perished so
the contract was void for common
mistake as both parties thought they
were making an agreement when in
fact there was no existence of the
goods.
McRae v Commonwealth Disposals
Commission: CDC sold the claimant a
shipwreck of a tanker supposedly
containing oil. However no tanker
even existed but the courts still found
that the claimant succeeded in claims
for damages for breach of contract
and rejected the contract be void as
CDC promised that the tanker did
exist.
The distinguish between these two cases
is that CDC had actually promised of the
existence when Hastie had not promised
anything.
Res Sua: a person
makes a contract to
purchase something
that in fact already
belongs to him.
Cooper v Phibbs: a nephew rented a room
off his uncle who then died. He then paid
rent to his aunt when in fact it was later
found the uncle had left a life time tenancy
to his nephew in his will. The lease was held
to be voidable for mistake as the nephew
already had a beneficial ownership right.
Mistake as to quality
A mistake as to
quality of the
subject matter of
a contract has
been confined to
very narrow
limits.
Bell v Lever Bros: Mr Bell was appointed as
chairman as well as Mr Snelling to run the
company Niger. Under contracts, the contract
was due to run for 5 years. However due to
poor performance, the merged with another
subsidiary and made the defendant
redundant. Bell accepted the substantial pay
out off Lever Bros for the termination of his
contract but it was later found they had
seriously brached heir contract which would
have lead to their termination anyway.
This was only a mistake as to quality and did not
render the contract essentially different from
that which it was believed to be. The action
therefore failed.
Leaf v International Galleries: Lead purchased a
painting form the defendant. Both parties believed
the painting to be by the artist Constable. 5 years
later they realised it wasn't. Leaf brought a claim
for misrepresentation and mistake.
The claim for
misrepresentation
was successful
(innocent) but lost the
right to rescind
because of a lapse of
time as he had left it 5
years.
Claim for mistake was
unsuccessful as the mistake
related to the quality and
did not render the subject
matter something
essentially different from
that which was believed to
be. He believed he was
buying a painting and he
got a painting.
Associated Japanese Bank v
Credit Du Nord:AJB bought
machines from a client and then
leased them back to him under a
guarantee from CDN. The client
went bankrupt so AJB sued CDN
on the guarantee. It turned out
the machines never existed, and
as they were fundamental to the
guarantee there was no contract
- it was void.
If a mistake is to effect the validity of a
contract it must be an operative
mistake (the reason the contract is
void)
Common Law
When the mistake is
operative, the contract is
usually void ab initio
(from the beginning) and
no property will pass
under it and no
obligations can arise
under it.
Equity
Even if the contract
is valid at common
law, in equity
(fairness) the
contract may be
voidable on grounds
of mistake. This
means the contract
is able to be void but
does not have to be.
Mutual Mistake
Where both parties
fail to understand
each other.
The courts will apply an
objective test and consider
whether a "reasonable man"
would take the agreement
to mean what one party
understood it to be or what
the other party did.
If the test leads to the conclusion that the
contract could be understood in one sense
only then both parties will be bound by this
contract in the sense that it is to be
understood.
Wood v Scarth: a lease was drawn up concerning a
pub, after a conversation, the sellers clerk
accepted the rent from the buyer only believing it
to be £63. However the seller intended to receive a
£500 premium from the buyer.
The contract was upheld on the
buyers terms because of the extra
evidence of the clerk which had
misled the buyer.
If the transaction is totally
ambiguous under the objective test
then there will be no consensus ad
idem and the contract will be void.
Raffles v Wichelhaus: a cargo had been
bought, however there was two ships of the
same name. The buyer thought he was
buying one whilst the seller thought he was
buying the other.
The case was too hard to decide and
too ambiguous so the contract was
void.
Scriven Bros v Hindley: the defendant bid for two lots
believing them to be of the same category because
they contained the same shipping mark. He refused
to pay for one of the lots (of lower value). The
auctioneer believed that the bid was made under a
mistake as to the belief of the value of the lot.
As the parties were not at ad idem, the plaintiff could
only recover if the buyer were estopped from relying the
truth. They were not estopped since their mistake had
been caused by the negligence of the seller.
Unilateral Mistake
Where only one party is mistaken.
Mistake as to terms of the contract
One party is mistaken as to the
nature of the contract and the other
party is aware of the mistake then
the contract is void.
Hartog v Colin & Shields: the defendant mistakenly offered a large quantity
of hare skins at a certain price per pound whereas
they are meant to be offered at that price per
piece. This meant the price was roughly one third
of what it should have been, to which the claimant
accepted.
The court held that the contract was void for
mistake. Hare skins were generally sold per piece
and given the price the claimant must have
realised the mistake.
Mistake as to identity
A party makes a contract with a second party
believing it to be someone else. The law makes a
distinction where the parties are inter absentes or
inter praesentes.
Inter absentes
Cundy v Lindsay
Kings Norton Metal v Etridge
Inter praesentes
Unilateral Mistake
Shogun v Hudson: a rogue purchased a car
on hire purchase terms and showed the ID
of a Mr Patel and granted the finance. He
paid a 10% deposit but then sold the car to
Mr Hudson and then disappeared.
Where a private purchaser buys a
motor vehicle from someone who has
it subject to a hire purchase
agreement and does not yet properly
own the vehicle, if he buys in good
faith and without notice of the hire
purchaser, the transaction is treated
as if the person selling the vehicle did
properly own it.
Phillips v Brooks: a rogue purchased some items from the claimants
jeweller's shop claiming to be Sir George Bullogh. He paid by checque and
persuaded the jeweller's to allow him to take a ring immediately as he
claimed it was his wives birthday the following day. He gave the address of
Sir George Bullogh and the jeweller's checked the name and address
matched. He then pawned the ring under the name of Mr Firth. The claimant
brought an action as to unilateral mistake as to identity.
The contract was not
void for mistake. Where
the parties transact
face to face the law
pressumes they intend
to deal with the person
in front of them not the
person they claim to
be. The jewellers were
unable to demonsrtate
that they would have
sold the ring to Sir
George Bullogh.
Ingram v Little: two sisters sold their car to a rogue
under he name Hutchinson and paid cheque
giving his full name and address to which she
checked at the post office. The cheque was
dishonoured and the car was sold on to Mr Little.
The sisters brought an action to recover the car.
The contract was void for
mistake. The Court of Appeal
held that the sisters only
intended to deal with Mr
Hutchinson at the address
given because they were not
willing to offer a sale by
payment of cheque from
anyone else.
This case has been criticised and
has not been followed since.
Lewis v Avery: The claimant sold his mini to a
rogue claiming to be the actor Richard Greene.
The rogue showed the claimant a Pinewood
Studio pass which had his details on it. The
cheque was dishonoured and the car was sold on
to Mr Avery. The claimant sought to return the car
on grounds that the contract was void for
mistake.
It was not void for mistake. The pressumption
that the parties intend to deal with the person
in front of them was not displayed.
Documents
A person is bound by their
signature to a document
whether or not they have read
and understood the document.
L'Estrange v Graucob: The claimant purchased a
smoking vending machine. She signed an order
form with the small print "any express or
implied, condition, statement of warranty,
statutory or otherwise is expressly excluded.
By signing the agreement, she was
bound by all terms in the form
regardless of whether she had read
them or not. It was her duty to read
everything contained in the form.
However, if a person has been induced by a
fraudulent misrepresentation, the transaction
will be voidable.
Saunders v Anglia Building Society: Mrs Gallie signed a
document which stated it was the sale of her interest in her
home to Mr Lee. He then used the document to obtain a
mortgage on the property for £2,000. He failed to keep up
payments so the building society sought possession of the
house. She had signed the document without her glasses.
She sought to claim repossession for non est factum (not
her deed) as it was only a gift to help raise money for Mr Lee
and her nephew.
The House of Lords
found against Mrs
Gallie as the
document she had
signed was not
radically different to
the one she believed
it to be which was
that she was
relinquishing the
rights to her
property.
The House of Lords
stated that non est
factum should not
be too widely
applied and
reserved it for those
who could for no
fault of their own
read the document
i.e. illiterate or
incapacitated
through age.
For such a plea
to be applied
there must be
two factors
established: 1.
the signer was
careless of
signing 2. there
is a radical
difference in
what the singer
thought they
were signing.
