rectification and recission

what is a contract

• an agreement with offer, acceptance, and consideration amounting to a meeting of the minds 

• Sometimes it is negotiated orally 

• Parties often depend on the good faith of the other party who writes the contract and will maybe just read the main terms of the contract and not is much the minor. 

• Party may discover that a part of the contract doesnt reflect the prior oral agreement 

• Court would establish that this isn't a contract 

rectification

Rectification is an equitable remedy used to correct a written contract/document so it reflects the true agreement of the parties.

It does not create a new contract—it fixes the written record to match what was actually agreed.

courts use it typically where;

• Parties had a prior agreement (often oral)

• The written contract fails to reflect that agreement

• One or both parties intended something different from what was written

Rectification is an equitable remedy used where a written contract does not reflect what the parties actually agreed.

The key idea is that the real agreement comes first (often oral or informally agreed), and the written document is supposed to record it.

If the document contains a mistake, the court does not “change the contract” as such, but instead corrects the written instrument so it matches the true prior agreement.

Because courts are being asked to override a signed document, the burden of proof is high:

• the party seeking rectification must show, on the balance of probabilities, that there was a clear prior agreement on the term in question and some outward evidence that both parties intended that same deal.

when does rectification apply

common/mutual mistake

• Both parties agree orally → written contract misrecords it.

  Example:

  • Oral deal: 50k units

  • Written contract: 5k units
    👉 Court fixes it to 50k

unilateral mistake

• One party is mistaken about the written terms AND:

  • the other party knows

  • and tries to take advantage

  This is where “inequitable conduct” comes in.

• Equity intervenes if:

  • A thinks clause X is included

  • B knows it’s NOT included

  • B stays silent to benefit

• Must show prior agreement or common intention

mutual or common mistake rectification

Arises where both parties actually agreed on something, but the written contract fails to reflect it due to a drafting error.

The court will only intervene where there is strong evidence of what was truly agreed.

A key point is that negligence in drafting is generally not a defence in equity, so the fact that one party signed without noticing an error does not automatically prevent rectification.

In practice, rectification is usually straightforward where there is clear proof of a shared intention, but it becomes harder where the alleged agreement is unclear or incomplete.

unilateral mistake rectification

It is different and more restrictive.

It applies where only one party is mistaken about the content of the written contract, but the other party knows about the mistake and takes advantage of it.

This is treated as inequitable behaviour.

The law is concerned with situations where one party is aware that the document does not reflect what the other party thinks they agreed, and still allows the mistake to stand. In such cases, equity may step in to correct the document to prevent unfair advantage.

Unilateral mistake rectification overlaps with ideas of fraud in a civil sense (not criminal fraud).

It can arise where one party believes a term exists in the contract, relies on it, and the other party knows it is missing but stays silent.

Equity may treat this as unconscionable behaviour, allowing rectification. However, this is distinct from cases where there was never any prior agreement at all.

approaches to rectification

The approach to rectification can be seen as having a “majority” and “minority” view.

The majority view is objective:

• the court focuses on whether the written document matches the proven prior agreement, regardless of what was in the parties’ minds at the time of signing.

The minority view is more subjective:

• focuses on whether the defendant acted inequitably, especially whether they knowingly exploited the other party’s mistake.

This distinction affects outcomes in borderline cases, particularly where one party signed without carefully reading the document but genuinely believed everything was correct.

elements of contract, and when breached, damages can used as a remedy

• Offer 

• Acceptance 

• Consideration 

termination

Termination for breach ends the contract because of a serious breach and only for the future, whereas equitable rescission is a remedy that unwinds the contract entirely and restores the parties to their pre-contract position because of a defect in consent such as misrepresentation or mistake.

another type of recission is when the parties think they have a contract but they dont**

reffels v wickleshouse

• Leading case relating to product on ship across the Atlantic Ocean  

• Had to be on a ship named Piores - two different ships called this 

• Even though there was offer acceptance consideration, contract was rescinded. 

copper v fibs**

both parties thought the uncle owned the land, but it turned out the nephew actually owned it. Because of that, the agreement was based on a false assumption.

The court said the contract could be rescinded and the money paid could be given back, because the whole deal only existed due to that shared mistake.

The basic idea is: if both sides are fundamentally wrong about something important, the court can cancel the contract and try to put them back where they started.

equitable defences against recission

• Equity won’t always allow rescission if it would be unfair or impossible to undo the contract properly.

  • For example, if the contract has already been partly performed and the benefits can’t realistically be given back, rescission may be blocked.

• It can also be refused if a third party has gained rights in the contract, or if someone has acted as a volunteer relying on it.

• Finally, if the person seeking rescission waits too long or keeps benefiting from the contract after knowing about the problem, the court may say they’ve waited too long and refuse to undo it.

Gunn v McCarthy

The landlord thought the rent in the contract should have been higher, but the written agreement only stated a lower amount, and the tenant knew what was written and relied on it.

The landlord tried to fix this through rectification, but the court refused and instead treated it as a case where there was no true “meeting of minds,” so rescission was appropriate.

The case highlights the difference between rectification and rescission:

• rectification applies where a written contract fails to reflect a prior agreed intention, especially where one party knowingly lets a mistake stand,

• while rescission applies where there was a fundamental mistake affecting the agreement itself.

• In mutual mistake cases, rescission is only allowed where the mistake is serious and radical, not just a normal dispute about terms or interpretation, as shown in cases like Solle v Butcher.

solle v butcher

a contract can sometimes be set aside where both parties are operating under a serious shared mistake (even a legal one), but only in limited cases. The court treats this as a situation where enforcing the contract as-is would be unfair because it was based on a fundamental misapprehension.

However, not every mistake qualifies — only serious and radical mistakes will justify rescission.

facts:

• Landlord and tenant agreed rent of £250.

• Tenant later argued rent should have been £140 under rent control law.

• Both parties had misunderstood the legal position.

• Landlord believed market rent was valid due to improvements.

decision:

• Court allowed the contract to be set aside (rescinded in equity).

• Neither party got the benefit of the mistaken assumption.

• Parties had to renegotiate a new lease if they wanted one.

misrepresentation

Misrepresentation is mainly dealt with as a remedy after a contract has been formed, not during informal negotiations or promises.

It usually arises where a party enters a contract based on false information given by the other side.

Misrepresentation can be either intentional or innocent.

• Intentional misrepresentation includes situations where a person knowingly lies or is reckless about the truth of what they are saying.

• Innocent misrepresentation occurs where someone believes what they are saying is true but it turns out to be wrong, and they were not trying to mislead the other party.

• In some cases, negligence can also play a role if the person failed to check something they reasonably should have known.

Misrepresentation can also lead to rescission rather than rectification.

Fraudulent misrepresentation allows a contract to be unwound even after performance if a party was induced to enter the contract by a false statement.

Innocent misrepresentation is where a statement is made honestly but turns out to be false, and in some cases this can also justify rescission if it is material and relied upon.

Silence can amount to misrepresentation where there is a duty to disclose or where one party relies on a changed statement that is not corrected before contracting.

However, not every misrepresentation will justify rescission, especially where the contract has already been fully executed.

negligent misrepresentation happens when someone makes a false statement carelessly — believing it to be true, but without taking reasonable care to check.

fraudulent misrepresentation

Fraudulent misrepresentation is treated very seriously in equity and can allow a contract to be rescinded, even after it has been fully performed.

The key idea is that the false statement must have induced the other party to enter the contract. T

he purpose of rescission is to put the parties back in the position they were in before the contract was made.

However, not every misrepresentation will allow this remedy, especially once the contract has been fully carried out, particularly in cases of innocent misrepresentation.

innocent misrepresentation

For innocent misrepresentation, rescission may be more limited.

If the contract has already been fully performed, it is often too late to undo it unless the misrepresentation is serious and material.

The courts also require that the misrepresentation led to a fundamentally different contract from what was actually agreed.

A key point is that parties are expected to protect themselves in contracts and not rely blindly on statements made by the other side, since contract parties are generally considered to be acting in their own interests.

recission vs rectification

Rectification corrects a written contract so it reflects the parties’ true prior agreement.

Rescission, on the other hand, unwinds the contract entirely and puts the parties back in their pre-contract position as if the contract had never been made.

Monaghan County Council v Vaughan [1948] IR 306

The County Council invited tenders to demolish a building. The defendant Vaughan submitted a tender and work began. However, the final written contract mistakenly stated that the Council would pay Vaughan £1,200, when the real agreement was the opposite—Vaughan was supposed to pay the Council.

The Council sought rectification of the contract so it reflected the true agreement.

the court granted rectification

• Rectification is available where a written contract does not reflect the parties’ prior common intention.

• The court looks for a clear prior agreement (oral or evidenced conduct) and checks if the written document fails to match it.

• It does not matter if one party noticed the mistake at the time, as long as there was a shared underlying agreement.

• Negligence is not a defence to rectification in mutual mistake cases.

• Estoppel did not apply because there was no reliance on a misrepresentation.

• Even formal requirements (like a council seal) do not prevent rectification.

Irish Life Assurance Co Ltd v Dublin Land Securities Ltd [1989]

Irish Life agreed to sell a large portfolio of ground rents to Dublin Land Securities. During drafting, a mistake occurred: certain valuable properties at Palmerstown (subject to compulsory purchase orders) were mistakenly included in the contract, even though Irish Life did not intend to sell them.

Irish Life argued that both parties had a mutual mistake and sought rectification to remove those properties from the contract.

However, the buyer argued that:

• the written contract reflected the final agreed deal, and

• there was no clear shared intention to exclude the properties.

The High Court refused rectification, and the Supreme Court upheld that decision.

held:

• no rectification

• The claimant failed to prove a common continuing intention to exclude the disputed properties.

The Supreme Court stressed that rectification is only available where there is:

• a clear shared intention between the parties on the disputed term, and

• that intention continued right up to the moment of signing, and

• the written contract fails to reflect it.

Here, the evidence did not clearly show that both parties agreed (or were clearly aligned) that the Palmerstown lands were excluded.

Gun v McCarthy (1883)

This case involved a dispute over a lease agreement for premises in Tralee. The landlord’s agent wrote a letter offering the defendant a lease at a rent of £33 10s, but the court later found that this figure was actually a mistake, and the intended rent was likely £53 10s.

The defendant accepted the written offer and later signed a formal lease reflecting the lower rent. The landlord then tried to have the lease either:

• rectified (changed to reflect the higher rent), or

• rescinded/cancelled (set aside entirely)

The central issue was whether equity could interfere where:

• one party made a mistake in drafting, and

• the other party knew or suspected the mistake but proceeded anyway

Flanagan J held:

• There was no true mutual mistake justifying rectification in the strict sense.

• However, the defendant knew the figure was wrong and tried to take advantage of it.

• That conduct was treated as unconscientious / inequitable, even if not strict fraud.

• Because of this, the court refused rectification but instead ordered rescission (cancellation) of the lease.

A Roberts & Co Ltd v Leicestershire County Council (1961) Ch

A council invited tenders for the construction of a school. Roberts initially submitted a tender but left the completion time blank. After negotiations, Roberts submitted a revised tender of £138,399 which expressly provided for completion within 18 months of instructions to commence work.

The council wanted a longer period and instructed its officials to draft a contract providing for 30 months instead. It then informed Roberts that its tender had been accepted and sent the formal contract. The council did not highlight the change in completion period, and Roberts signed without noticing.

At later meetings, Roberts repeatedly referred to the 18-month completion period and the council did not correct them. Roberts only discovered the discrepancy much later and sought rectification of the contract.

the court granted rectification, but only on a unilateral mistake with knowledge basis, not true common mistake.

• Roberts genuinely believed the contract still contained the 18-month term

• The council knew (or must have known) Roberts held that belief

• The council nevertheless allowed the contract to be signed and later said nothing when Roberts continued relying on the 18-month assumption

👉 This made it unconscionable for the council to insist on the written 30-month term.

Solle v Butcher

Involved a landlord leasing a flat to a tenant for £250 per year. Both parties believed the flat was not subject to the Rent Acts. In reality, the Rent Acts applied, meaning the lawful rent was only around £140 unless a proper notice increasing the rent had been served.

When the tenant discovered this, he sought repayment of the excess rent. The landlord argued that the lease should be rescinded because both parties had entered the agreement under a fundamental common mistake about the legal status of the flat.

The Court of Appeal held that although the contract was not void at common law, it could be set aside in equity because both parties shared a fundamental misapprehension.

The court allowed rescission on equitable terms — meaning the lease could be undone provided the landlord offered a new lease at the intended rent with the correct legal notice.

case established that

• even where a contract is valid at common law, equity may allow rescission if:

  • both parties shared a fundamental misunderstanding about facts or legal rights; and

  • it would be unfair or unconscionable to let one party benefit from that mistake.

Great Peace Shipping Ltd v Tsavliris Salvage (International) Ltd [2003] QB 679

concerned a salvage operation involving a damaged ship, the Cape Providence, stranded in the Indian Ocean.

Tsavliris Salvage urgently needed a nearby vessel to assist in case the crew had to be rescued. Brokers were mistakenly informed that the ship Great Peace was only about 35 miles away from the damaged vessel. In reality, it was over 400 miles away.

Believing the ships were close together, Tsavliris chartered the Great Peace. Once the true distance was discovered, Tsavliris tried to cancel the contract, arguing there had been a common mistake.

Held:

• The Court of Appeal held that the contract was not void for common mistake.

• Although both parties were mistaken about the distance between the ships, the mistake was not sufficiently fundamental to destroy the basis of the contract. The Great Peace could still perform the service — it was simply less useful and more inconvenient than expected.

• The court also rejected the idea from Solle v Butcher that equity could separately rescind contracts for common mistake.

established that:

• A contract is only void for common mistake where:

  • both parties share the same mistake;

  • the mistake concerns a fundamental assumption underlying the contract; and

  • the mistake makes performance essentially impossible or radically different from what was agreed.

a mere bad bargain or inconvenience is not enough

Northern Bank Finance Corp Ltd v Charlton [1979] IR 149

involved a group of businessmen attempting to take over a public company.

The defendants, along with other promoters, worked with Northern Bank to finance the takeover. The bank required each promoter to contribute a fixed amount of money before the bank would advance the larger loan.

One promoter secretly withdrew most of his contribution. The bank knew this but repeatedly told the defendants — falsely — that the promoter’s contribution remained intact and that he was not substantially indebted to the bank.

Relying on these representations:

• the defendants continued with the takeover scheme;

• they entered further financial arrangements; and

• they even bought out the fourth promoter’s shares using additional money loaned by the bank.

The takeover later collapsed and the shares became worthless. The bank sued for repayment of a loan, while the defendants argued they had been induced into the transactions by fraudulent misrepresentation.

held:

• The Supreme Court upheld the finding that the bank had made fraudulent misrepresentations.

• The defendants were entitled to relief because they had been induced into the transactions by deceit.

• However, the Supreme Court limited the scope of rescission because full restitutio in integrum (restoring the parties completely to their original positions) was not fully possible.

• The case was sent back for assessment of damages for deceit.

Gahan v boland

The defendants, Maurice and Wendy Boland, were selling their property, “Glencarrig,” in County Dublin. The property included a house and surrounding lands, including a paddock.

The plaintiff, Donal Gahan, was interested in buying a property with land partly for family security. During an inspection of the property, Gahan asked questions about a proposed motorway planned for the area.

Boland made comments such as:

• “It will not be built in our lifetimes.”

• “It would be much too expensive to build the motorway through the glen.”

Gahan and his wife claimed they also specifically asked whether the motorway affected the property and were assured it did not.

In reality, Boland knew that part of the paddock might be affected by the motorway proposal, having previously been told this himself when he bought the property.

Gahan later sought rescission of the contract on the basis of misrepresentation.

Held:

The court held that certain statements made by Boland were merely speculative opinions about future events and therefore were not actionable misrepresentations on their own.

However, the court distinguished between:

• statements of opinion about whether the motorway would ever be built, and

• statements of fact concerning whether the motorway affected the property.

The court found that the discussion effectively involved a request for factual information about the location of the proposed motorway and whether it crossed the property.

Because Boland knew that at least part of the paddock might be affected, any representation suggesting otherwise could amount to a misrepresentation.

The case became important for the principle that:

• even informal statements during negotiations,

• particularly in property transactions,

• can amount to actionable representations where they concern material facts relied upon by the purchaser.

carroll v carroll

• Thomas Carroll Snr owned a public house and attached residence in Fethard, Co. Tipperary.

• The family had a close-knit, long-standing relationship, with the children working in or supporting the family business.

• After the death of his wife (who had effectively run the pub), the father:

  • was elderly (late 70s),

  • in poor physical health (arthritis, heart issues, hearing/vision problems),

  • and emotionally devastated.

• The son, Thomas Jnr:

  • had been actively involved in the pub and family farming arrangements,

  • and effectively took over day-to-day running after his mother’s death.

• In this context, the father executed a conveyance transferring the pub and property to his son, essentially:

  • “in consideration of natural love and affection”,

  • while retaining only a right of residence.

• After the father’s death, the daughters (as personal representatives) sought to set aside the transfer, arguing it was unfair and improperly influenced.

held:

The court in Carroll v Carroll [1998] IEHC 42 decided that the transfer of the pub and family home from the father to his son should be set aside (invalidated).

• Given the father’s age, poor health, emotional vulnerability after his wife’s death, and dependence on his children, the court was not satisfied that he acted with fully independent judgment.

• The circumstances created a strong enough concern that the transfer was not the product of truly free and informed decision-making. (undue influence)

Bank of Nova Scotia v Hogan [1996] 3 IR 239.

• Mr Hogan obtained a loan facility from the Bank of Nova Scotia.

• As security, he gave the bank equitable mortgages (deposit of title deeds) over several properties he owned.

• Later, his wife, Mrs Hogan, also deposited the title deeds of her own property (St Rita’s) with the bank.

The dispute centred on:

• whether Mrs Hogan’s property was validly used as security, and

• whether she had entered the arrangement freely or under undue influence / pressure.

The Supreme Court held:

• No undue influence was proved.

• The wife’s security over her property was valid and enforceable.

• The bank had not acted improperly or unconscionably.

A bank will not be fixed with undue influence in a guarantee/security transaction involving a spouse unless it has actual or constructive notice of improper pressure or unconscionability, or circumstances are sufficiently suspicious to require it to intervene.

arclays Bank plc v O’Brien [1994] 1 AC 180 (House of Lords)

• Mr O’Brien persuaded his wife to sign a mortgage guarantee over their family home.

• The guarantee secured Mr O’Brien’s business debts to Barclays Bank.

• Mrs O’Brien signed the documents at the bank.

• She later argued:

  • she did not fully understand what she was signing, and

  • her husband had misled or pressured her into agreeing.

Crucially:

• The bank did not ensure she received independent legal advice.

• The transaction was for her husband’s business benefit, not hers.

decision

The House of Lords held:

• The mortgage could be set aside (as against the bank).

• The bank was fixed with constructive notice of the risk of undue influence.

A bank may be bound by undue influence where:

1. There is a relationship of trust and confidence (e.g. husband–wife), AND

2. The transaction is not to the advantage of the weaker party, AND

3. The bank is aware (or should be aware) of the risk of influence, UNLESS it takes reasonable steps to protect the weaker party

If a transaction is potentially risky (e.g. wife guaranteeing husband’s debt), the bank should:

• insist the guarantor receives independent legal advice, OR

• take steps to ensure the spouse understands the nature and consequences of the guarantee.
