Title: Unilateral Mistake
1Unilateral Mistake
2What Is This, and Why Is It Problematic?
- This is one of the most dangerous types of
mistake for the court to accept too easily. - If it is accepted too easily, then it allows a
court to worry more about what one of the parties
says was their intention at the time of contract. - This inherently cannot be said to be the
intention of the parties but rather the
intention of one party.
3Mistake (contd)
- Yet, the tension on the other side of the
equation is that the courts do not want to force
what is clearly a bad deal down the throat of one
party when it is clearly established that there
is a substantial injustice to one of the parties,
and/or a substantial windfall to the other of
them.
4Mistake (contd)
- Therefore, the courts are forced to walk a
tightrope between - Doctrinal purity (adherence to the law as
established, which is in favour of upholding
those agreements that appear to be contracts)
and - The desire to do what appear to be justice in a
given case (which would at least sometimes seem
to require that the rules not be applied so
inflexibly as to disallow a remedy to a party
that appears to be deserving of it)
5Mistake (contd)
- The hardliners would say that the idea of doing
justice is fine in the abstract, and even in the
context of the particular case, but it is very
difficult to lay out in advance rules that are
principled for future cases on the basis that
they are just. The law of contract depends on
the ability of parties to know what their rights
are when entering into the contract.
6Mistake (contd)
- Those who promote the opposite view see law as
only a means to an end. The end in this case is
justice. Therefore, if the law does not achieve
its desire end justice then as the old adage
goes, the law is an ass. - The distinction between these two extremes is
clearly presented in disagreement between the
majority and the dissent in the next case. Note
that the dissent represents the law in Canada and
the U.K.
7Mistake (contd)
- The seller of goods, services or land knows their
true quality. The buyer, however, does not know
the quality of the horse, the habitability of the
house, or the number of customers for the garage.
After the purchase is made by the buyer, the
buyer becomes aware of the true value of the
subject-matter.
8Stambovsky v Ackley
- The plaintiff bought a house that was known in
the local community to be haunted. When this
became clear to the plaintiff, the plaintiff
sought to rescind the contract. - This occurred prior to closing (so execution is
not a bar to rescission) (paragraph 17) - The court refuses to allow the defendant to argue
that the house is not haunted, because the
defendant - The court says that there was no way that the
buyer could have discovered this (paragraph 4).
9Stambovsky v. Ackley (contd)
- In general, silence without more is insufficient
to allow rescission unless there is - Confidential relationship
- Fiduciary relationship or
- Active concealment
- This is an equitable concept (paragraph 6)
- Having mentioned the haunting as a point of
interest for others, she owes at least the same
to the contractual party (paragraph 12)
10Stambovsky v. Ackley (contd)
- As a matter of remedy
- Misrepresentation
- Warranty
- Voidable for fundamental mistake (Dennings view
from Solle v. Butcher Common mistake case,
could be applied to unilateral mistake as well)
11Stambovsky v. Ackley (contd)
- The rule of caveat emptor places the
responsibility on the buyer to do due diligence,
ask questions, examine the subject-matter, and if
felt necessary, negotiate contractual protections - The reason for this is that at common law, the
solution to a finding of mistake is rather
draconian there is no contract, and there never
was one.
12Smith v. Hughes
- The plaintiff thought that he was selling new
oats, which he was. The defendant looked at a
sample and thought that was buying old oats.
There was no mention of whether the oats were old
or new. - The defendant wants out of the contract the
plaintiff wants to get paid
13Smith v. Hughes (contd)
- Paragraph 12
- The parties must agree on the same thing in the
same sense. That is, if A thought that the terms
of the contract were X, and in fact the terms
were otherwise, there is no contract. - Paragraph 13
- When one party causes the mistake as to terms, it
is a breach, this is not a mistake which will
entitle the party at fault to undo what would
otherwise be a contract
14Smith v. Hughes (contd)
- Paragraph 15
- If one party know that the other is mistaken as
to terms, then you cannot force them to live with
that mistake - If the word old had been used by the plaintiff,
then there would have been a breach of contract,
given that the seller would be unable to deliver
what was promised.
15Smith v. Hughes (contd)
- If one knows that the other party is mistaken as
to the terms of the contract, then the contract
is void (paragraphs 12 and 15). - This does not apply if the mistaken party induces
the contract, but makes a mistake as to terms
(paragraph 13)
16Smith v. Hughes (contd)
- However, if the mistake is only as to the quality
of the goods (as opposed to the terms of the
contract), then there is no mistake which would
invalidate the contract (paragraph 16)
17Hartog v. Colin Shields
- The plaintiff made a deal to buy rabbit skins
from the defendant. - The defendants said that their offer to sell
contained a mistake, and that the plaintiff would
have known it simply by looking at the offer. - The negotiations had been per piece, not on a per
pound basis. - The offer was expressed on a per pound basis,
which made it cheaper for the plaintiff buyer to
purchase than the defendant intended.
18Hartog v. Colin Shields (contd)
- Anybody would have known something was up
- When the mistake is contained within the offer,
and the non-mistaken party is the offeree, the
attempt to form a contract by accepting the
offer, this is called snapping up the offer
(paragraph 2). - If one knows that the other party is mistaken as
to the terms of the contract, then the contract
is void
19Mistake (contd)
- Construction contracts
- The offers in construction contracts tend to be a
bit different than other offers. - They are often built on a system of tenders.
- The thing about this is that replaces negotiation
with competition - To allow people out for unilateral mistake as to
terms in these circumstances adds uncertainty no
only to the relationship between the offeror and
the owner, but also to the tendering system as a
whole.
20Imperial Glass Ltd. v. Consolidated Supplies Ltd.
- The appellant is a supplier and installer of
window panes the respondent is a manufacturer of
a particular type of windows. - October, 1957 The appellant is asked to bid on
a construction project. Before making a bid, the
appellant phoned the respondent. An employee of
the respondent miscalculated the square footage
by 90 per cent, and quoted 2,000 as a price.
21Imperial Glass Ltd. v. Consolidated Supplies Ltd.
(contd)
- October 11th, 1957 Tender submitted
- November 6th, 1957 Bid accepted
- December 11th, 1957 Confirmation provided
- December 13th, 1957 Order placed
- December 17th, 1957 Mistake discovered
- December 23rd, 1957 Offer revoked
22Imperial Glass Ltd. v. Consolidated Supplies Ltd.
(contd)
- The trial judge held that the quotation given in
October was not an offer to sell. The Court of
Appeal agrees (paragraph 11) - The trial judge held that a binding contract was
entered into when the appellant on December 13th
accepted the respondent's offer made in on
December 11th. The Court of Appeal agrees.
23Imperial Glass Ltd. v. Consolidated Supplies Ltd.
(contd)
- The trial judge held that the respondent had
knowledge of the appellants mistake. The Court
of Appeal says that they will not disturb this
finding
24Imperial Glass Ltd. v. Consolidated Supplies Ltd.
(contd)
- There is no mistake in the offer here (paragraphs
12 and 18) - This is not like Solle v. Butcher (paragraph 16)
Common mistake (the court calls it mutual
mistake) - Therefore, Hartog v. Colin Shields does not
apply because the mistake is not in the offer
itself
25Imperial Glass Ltd. v. Consolidated Supplies Ltd.
(contd)
- The mistake is not relevant because
- There was no fraud on the part of the
non-mistaken party (paragraph 19) - There was negligence on the part of the mistaken
party (paragraph 20)
26Buffalo Municipal Housing Authority v. Gross
Plumbing Heating Co.
- The defendant was a contractor who bid on a
project involving the plaintiff. The defendant
put in a bid bond to ensure that if the bid were
accepted, the bid would not be revoked. It
turned out that there was a substantial clerical
error in the bid to the tune of almost 89,000.
27Buffalo Municipal Housing Authority v. Gross
Plumbing (contd)
- The defendant immediately notified the plaintiff.
The plaintiff seeks to keep the bid bond. The
plaintiff could see the error by reviewing the
supporting documentation - This is not the law in Canada
- The plaintiff could have simply offered the
chance to fix this and this reject the bid, or
accept if so inclined.
28Buffalo Municipal Housing Authority v. Gross
Plumbing (contd)
- The negligence of the bidder does not deny
relief, that is, the bidder can still get out of
the contract based on a mistake in the offer if
that mistake means that the parties were not ad
idem - The distinction between errors as to terms and
those of calculation is not a meaningful one.
29Buffalo Municipal Housing Authority v. Gross
Plumbing (contd)
- Therefore, we ought to look to ensure that
- The error is clerical in nature business errors
will not suffice - The error is sufficiently large that to allow the
plaintiff to enforce the contract so create would
be unconscionable. - If so, then the court will say that there is a
unilateral mistake, and set aside the contract - Negligence of the bidder is irrelevant here
30Ron Engineering v. Ontario
- The contract made an offer that (as it turned
out) was about 632,000 lower than the next
lowest bid. - The tender documents said that if the bid was
withdrawn, or the successful bidder refuses to
enter into the main contract, then the tender
deposit is lost. - The bidder realized that the tender was low prior
to the opening of bids. Upon realization that
this had occurred, the bidder tried to withdraw
the tender.
31Ron Engineering v. Ontario (contd)
- The owner accepted the lowest bid, and when the
contractor refused to complete the construction
contract, the owner accepted the second-lowest
bid - The contractor sued to recover the deposit the
owner counter-sued for damages - Not evident on the face of the tender (paragraph
10) - Contractor not trying to pull a fast one
(paragraph 10)
32Ron Engineering v. Ontario (contd)
- We need to protect the bidding system (paragraph
20) - Contract A v. Contract B
- Contract A is a unilateral contract (we will see
later that this is wrong), placing obligations on
the tenderer - If there is a mistake in calculation of the bid
made at the contract A stage, this is not a
legally relevant mistake unless the error would
be obvious on the face of the tender.
33M.J.B. Enterprises Ltd. v. Defence Construction
(1951) Ltd.
- Tendering process in which the owner said that
contingent bids were not allowed - The successful bidder put in a contingent bid
- MJB was one of the bidders whose tender was not
chosen. - The respondent claims that the privilege clause
a clause that says The lowest or any tender
shall not necessarily be accepted means that
they can accept any tender they like.
34M.J.B. Enterprises Ltd. v. Defence Construction
(1951) Ltd. (contd)
- Not every tendering process will necessarily need
a Contract A- Contract B analysis (paragraph 17) - Contract A is not unilateral, meaning that it can
place obligations on the owner (paragraphs 18-19)
- The content of Contract A is determined by the
terms of the tender call, depending on the
intentions of the parties (paragraphs 22-23)
35M.J.B. Enterprises Ltd. v. Defence Construction
(1951) Ltd. (contd)
- The privilege clause does allow the owner to
choose the bid that is not the lowest (paragraph
30). - But, the privilege clause does not give the owner
the right to choose a non-compliant bid
(paragraph 30).
36Martel Building Ltd. v. Canada
- Martel leased most of a building to the
government.  Prior to the end of the lease, the
landlord's CEO met a subordinate of the
governments Chief of Leasing to discuss renewing
the lease.  - The Chief of Leasing to obtain a proposed rental
rate even though it intended to commence a tender
process but  no action was taken.Â
37Martel Building Ltd. v. Canada (contd)
- Â The Chief of Leasing did not contact Martel when
directed to report on the status of negotiations
and, at monthly meetings, led the appellant to
believe that a proposed lease rate was
forthcoming but nobody informed the respondent of
this expectation. Â
38Martel Building Ltd. v. Canada (contd)
- The respondent's CEO twice contacted the
appellant,  resulting in a meeting which the CEO
believed was to commence negotiations but in
which the appellant maintains that it told the
CEO that it would proceed to tender unless it
received a very attractive offer. The CEO
presented proposed rental rates that fell outside
a range suggested by an appraisal commissioned by
the appellant.
39Martel Building Ltd. v. Canada (contd)
- The appellant set a date to complete negotiations
and, when that date passed, began steps to
approve a tender by preparing a report. The
report first recommended a lease renewal but no
final decision was made before a revised report
recommended proceeding to tender due to declining
market rental rates.
40Martel Building Ltd. v. Canada (contd)
- Approval for a tender was obtained.  The CEO
heard rumours that a tender was to begin and
telephoned the Chief of Leasing.  The parties met
the same day an expression of interest was
advertised to solicit interest in the tender. - The CEO said he left the meeting with an
understanding that the appellant would recommend
a lease renewal if he offered a rate of 220 per
square metre.  Two days after the meeting, he
advised the Chief of Leasing that he could offer
that rate
41Martel Building Ltd. v. Canada (contd)
- However, the appellant decided that remaining
terms would have to be settled that day. The
respondent could not respond that quickly.  Its
offer was rejected and tender documents were
issued.  Under the terms of the call for tenders
the appellant was not obligated to accept the
lowest bid.
42Martel Building Ltd. v. Canada (contd)
- The respondent submitted the lowest of four bids.
The appellant conducted a financial analysis of
the bids to consider the total costs that would
be incurred as a result of accepting any one
tender and added to the respondent's bid
approximately 1,000,000 for fit-up costs and
60,000 to cover the installation of a secured
card access system.  The tender was awarded to a
competitor.
43Martel Building Ltd. v. Canada (contd)
- What is important, therefore, is that the
submission of a tender in response to an
invitation to tender may give rise to contractual
obligations, quite apart from the obligations
associated with the construction contract to be
entered into upon the acceptance of a tender,
depending upon whether the parties intend to
initiate contractual relations by the submission
of a bid. If such a contract arises, its terms
are governed by the terms and conditions of the
tender call.
