Welcome to Contract Law (AQA A Level Law 7162 – Paper 3)
Welcome to your complete revision guide for The Rules and Theory of Contract Law. Contract law is everywhere in daily life: every time you buy a coffee, download a mobile app, or take a bus ride, you enter into a legally enforceable agreement. Don't worry if legal tests seem overwhelming at first; we will break down every rule, case, and statutory section step-by-step.
For Paper 3 (Option A: 7162/3A), you need to master two key aspects:
1. The Rules of Contract Law: The substantive legal tests and statutory rules.
2. The Theory of Contract Law: Evaluative ideas linking contracts to Freedom of Contract, Consumer Protection, Justice, and Morality.
Part 1: The Essential Requirements of a Contract
To form an enforceable contract, the law requires four core ingredients: Offer, Acceptance, Consideration, and Intention to Create Legal Relations (ICLR).
1. Offer vs. Invitation to Treat
An Offer is a clear, definitive statement of terms upon which the offeror is willing to be bound. It must be clearly distinguished from an Invitation to Treat (ITT), which is simply an invitation to make an offer or enter negotiations.
• Shop Displays: Items displayed in a shop window or on shelves are invitations to treat, not offers.
Authority: In Fisher v Bell, displaying a flick knife with a price tag in a shop window was held to be an invitation to treat, not an offer for sale.
Authority: In Partridge v Crittenden, classified advertisements in a magazine were held to be invitations to treat, not offers.
• Counter-Offers vs. Requests for Information:
If the offeree introduces a new term or alters the price, this is a counter-offer. A counter-offer immediately destroys ("kills") the original offer so it can no longer be accepted (Hyde v Wrench). However, a simple inquiry or request for more information leaves the original offer open.
2. Acceptance & The Postal Rule
Acceptance must be a complete, unconditional agreement to all terms of the offer. Under the mirror image rule, the acceptance must match the offer exactly.
• General Rule: Acceptance is only valid when communicated to and received by the offeror.
• The Postal Rule Exception: When acceptance by post is within the contemplation of the parties, acceptance takes effect the very moment the letter is posted, not when it arrives.
Authority: Adams v Lindsell established that posting the letter completes the contract immediately, even if the letter is delayed.
3. Consideration & Privity of Contract
Consideration is the price for which the promise is bought. The essential rule is that consideration must be sufficient, but need not be adequate. This means it must have some recognizable legal value (sufficiency), but courts will not judge whether it is a fair commercial price (adequacy).
• Privity of Contract: Under the doctrine of privity, only those who are parties to a contract can sue or be sued on it. A third party cannot enforce a promise even if made for their benefit.
4. Intention to Create Legal Relations (ICLR)
Both parties must intend their agreement to have binding legal consequences. The law applies two rebuttable presumptions:
• Domestic and Social Agreements: There is a strong legal presumption that parties do not intend to create legal relations.
Authority: In Balfour v Balfour, an agreement between a husband and wife living together was held not to be a legally enforceable contract.
• Commercial Agreements: There is a strong legal presumption that parties do intend to create legally binding relations.
Authority: In Edwards v Skyways, the court confirmed that in commercial transactions, the burden of proving that no legal relations were intended is extremely heavy.
Key Takeaway for Formation: An agreement needs a valid Offer met by an exact Acceptance, supported by sufficient Consideration, and backed by a clear Intention to Create Legal Relations.
---Part 2: Contract Terms and the Consumer Rights Act 2015
Contract terms set out what the parties have agreed to do. Terms are either Express (explicitly spoken or written) or Implied (inserted by common law or statute).
Classification of Terms
The remedies available for breach depend on the classification of the term:
1. Condition: A fundamental, vital term going to the root of the contract.
Effect of breach: The innocent party can terminate (repudiate) the contract and claim damages.
Authority: In Poussard v Spiers, an opera singer failed to perform for opening night. This was a breach of condition, entitling the producer to terminate the contract.
2. Warranty: A minor, subsidiary term that does not go to the root of the contract.
Effect of breach: The innocent party can claim damages only, but must carry on with the contract.
Authority: In Bettini v Gye, missing several days of rehearsals was a breach of warranty, so the employer could claim damages but could not terminate the contract.
3. Innominate Term: A term that cannot be easily labeled in advance.
Effect of breach: The court looks at the consequences of the breach. If the breach deprives the innocent party of substantially the whole benefit of the contract, it is treated like a condition; otherwise, it is treated like a warranty (Hong Kong Fir Shipping).
The Consumer Rights Act (CRA) 2015
When a contract is between a trader and a consumer, statutory terms are implied into the agreement automatically under the CRA 2015.
Statutory Terms for Goods
• Section 9: Goods must be of satisfactory quality (meeting the standard a reasonable person would regard as satisfactory taking into account price, description, and durability).
• Section 10: Goods must be fit for a particular purpose expressly or impliedly made known to the trader.
• Section 11: Goods must match their description.
Statutory Terms for Services
• Section 49: Services must be performed with reasonable care and skill.
• Section 52: Services must be performed within a reasonable time (where no specific time is fixed by the contract).
Statutory Consumer Remedies
• Section 20: Short-term right to reject goods (must be exercised within 30 days) leading to a full refund.
• Section 23: Right to repair or replacement of goods.
• Section 24: Right to a price reduction or the final right to reject if repair/replacement fails.
• Section 55: Right to repeat performance of a service that was not carried out with reasonable care and skill.
Key Takeaway for Terms: Check the status of the parties first! If a consumer is buying from a trader, apply the CRA 2015 sections directly. For common law terms, classify them as conditions, warranties, or innominate terms.
---Part 3: Vitiating Factors and Discharge of Contracts
A contract may appear validly formed, but can be invalidated by a vitiating factor or brought to an end by operation of law.
1. Misrepresentation
A misrepresentation is an unambiguous, false statement of material fact made by one party that induces the other party to enter the contract.
• Statements by Conduct: A false representation can be made through conduct rather than words alone.
Authority: In Spice Girls v Aprilia, participating in promotional video filming with all group members was held to be a misrepresentation by conduct that the group would remain together.
• Requirement of Inducement: The false statement must actually induce (influence) the claimant into contracting.
Authority: In Attwood v Small, because the purchaser relied on their own independent surveyor's report rather than the seller's exaggerated statements, there was no actionable misrepresentation.
2. Economic Duress
Economic duress occurs when a party enters or alters a contract due to illegitimate commercial pressure that leaves them with no realistic or practical alternative.
Authority: In The Universe Sentinel, the courts confirmed that illegitimate financial coercion overcoming the will of a party constitutes economic duress, rendering the contract voidable.
3. Discharge of a Contract
Discharge means the legal obligations under the contract have come to an end. A contract can be discharged in three primary ways:
• Discharge by Performance: The general common law rule is that performance must be complete, exact, and precise. Doing part of the job is not enough.
• Discharge by Breach: Where one party fails to perform their obligations. This can be an actual breach (failure when performance is due) or an anticipatory breach (one party states in advance that they will not perform).
• Discharge by Frustration: Occurs when an unforeseen event happens after contract formation, through no fault of either party, making performance physically impossible or radically different from what was agreed.
Authority: In Taylor v Caldwell, the accidental destruction of a music hall by fire before the planned concerts frustrated the contract and discharged both parties from liability.
Key Takeaway for Discharge: Contracts normally end through full performance, but can be terminated by a repudiatory breach or discharged automatically when unforeseen events trigger the doctrine of frustration.
---Part 4: Theory of Contract Law (Evaluation & Concepts)
In Paper 3, high-scoring essays require an understanding of the legal philosophy and theory underpinning contract rules. You must be able to discuss and balance the following concepts:
Freedom of Contract vs. Consumer Protection
• Freedom of Contract (Classical Theory): Rooted in 19th-century laissez-faire economics, this principle argues that competent parties should have absolute freedom to bargain, choose their terms, and take risks without interference by judges or parliament.
• Consumer Protection: In reality, individual consumers rarely have equal bargaining power when dealing with large commercial enterprises. Parliament intervenes via statutes like the Consumer Rights Act 2015 to level the playing field, protect weaker parties, and ensure baseline quality standards.
Links to the Nature of Law: Justice and Morality
• Justice: Contract rules attempt to balance procedural and substantive justice between competing parties. For example, the Postal Rule (Adams v Lindsell) provides commercial certainty for the offeree who relies on the post, preventing the offeror from arbitrarily retracting, thus balancing fairness.
• Morality: Contract law reinforces moral principles such as honesty (the rule against misrepresentation in Spice Girls v Aprilia), good faith, and accountability (holding parties responsible for duress under The Universe Sentinel).
---Part 5: Exam Success – Pitfalls to Avoid & The "Triangulation" Method
Examiner Pitfalls to Avoid:
1. Price Tags are NOT Offers: Never state that an item on a shelf or shop window is an offer. It is an Invitation to Treat (Fisher v Bell).
2. Counter-Offers "Kill" Offers: Do not confuse an inquiry for more information with a counter-offer. A counter-offer permanently extinguishes the original offer (Hyde v Wrench).
3. Check Inducement in Misrepresentation: If the scenario mentions that the buyer hired their own surveyor or relied on independent advice, the misrepresentation claim will fail for lack of inducement (Attwood v Small).
4. Use the Correct Act: Always use the Consumer Rights Act 2015 for business-to-consumer disputes, never older outdated legislation.
The Triangulation Technique
To secure maximum marks in 30-mark scenario questions, examiners look for seamless Triangulation in every point you make:
1. Legal Principle: State the exact legal rule or test clearly.
2. Authority: Cite the relevant case (e.g., Fisher v Bell) or statutory section (e.g., Section 9 CRA 2015).
3. Application: Apply the principle directly to the specific facts, items, and character names in the scenario to reach a clear conclusion.
