Questions & Detailed Explanations
Subtopic: Contract Formation, Terms, Vitiating Factors, and the English Legal
System
Question 1: Which of the following best distinguishes an offer from an invitation to treat within
the context of English contract law?
A) An offer is a statement of intent, whereas an invitation to treat is a binding promise to sell at a
specific price.
B) An offer displays a definitive willingness to be bound on specific terms, whereas an invitation
to treat is a preliminary approach inviting others to make an offer.
C) An invitation to treat requires a counter-offer to be legally binding, while an offer only
requires silence as acceptance.
D) An offer must be in writing to be enforceable, whereas an invitation to treat can be inferred
entirely through conduct.
Correct Answer: B) An offer displays a definitive willingness to be bound on specific terms,
whereas an invitation to treat is a preliminary approach inviting others to make an offer.
Explanation: An offer represents a clear manifestation of willingness to contract on specified
terms, such that a binding agreement arises upon acceptance. Conversely, an invitation to treat
is merely a step in the negotiation process, indicating a willingness to receive offers (e.g., shop
displays, advertisements). Option A is incorrect because an invitation to treat is never a binding
promise. Option C is wrong because silence generally cannot constitute acceptance. Option D is
incorrect as most simple contracts do not require a written form.
Question 2: In Carlill v Carbolic Smoke Ball Co [1893], what legal principle was established
regarding unilateral contracts?
A) A unilateral offer must be communicated to a specific individual to be accepted.
B) Acceptance of a unilateral offer must be notified to the offeror before performance.
C) Performance of the condition stipulated in the offer constitutes both acceptance and
consideration.
D) A unilateral contract cannot be enforced if the offer is made to the world at large.
,Correct Answer: C) Performance of the condition stipulated in the offer constitutes both
acceptance and consideration.
Explanation: The Court of Appeal held that in unilateral contracts, the act of performance serves
as the acceptance of the offer and provides the necessary consideration. Option A and D are
incorrect as unilateral offers can be made to the world. Option B is wrong because notification
of acceptance is typically waived in unilateral contracts, with the act of performance itself
sufficing.
Question 3: Which scenario below best illustrates the application of the 'postal rule' regarding
acceptance?
A) Acceptance sent by email is effective the moment the sender presses 'send'.
B) Acceptance by letter is effective upon being posted, provided the post is a reasonable method
of communication.
C) Acceptance by letter is effective only when the offeror opens the envelope and reads the
contents.
D) The postal rule applies to all forms of instantaneous communication, including fax and telex.
Correct Answer: B) Acceptance by letter is effective upon being posted, provided the post is
a reasonable method of communication.
Explanation: The postal rule creates a limited exception where acceptance is effective at the
point of posting (Adams v Lindsell). Option A is incorrect as the postal rule does not apply to
email. Option C is wrong because the rule focuses on the act of posting, not receipt. Option D is
incorrect as the rule specifically excludes instantaneous communication.
Question 4: Regarding consideration, which statement is legally accurate?
A) Consideration must be adequate, meaning it must reflect the fair market value of the promise.
B) Past consideration is always valid consideration if it was requested by the promisor.
C) Consideration must be sufficient, meaning it must have some identifiable value in the eyes of
the law, even if it is nominal.
D) A promise to perform an existing public duty can always be enforced as valid consideration.
Correct Answer: C) Consideration must be sufficient, meaning it must have some
identifiable value in the eyes of the law, even if it is nominal.
Explanation: English law requires consideration to be sufficient (possessing legal value), not
adequate (commercially equivalent). Option A is incorrect as courts do not intervene in the
, fairness of a bargain. Option B is incorrect as a general rule (Re McArdle). Option D is
incorrect because performing a pre-existing public duty is generally not consideration unless it
exceeds that duty.
Question 5: What is the primary effect of the doctrine of privity of contract?
A) It allows third parties to sue directly on a contract regardless of whether they provided
consideration.
B) It prevents a person who is not a party to the contract from enforcing, or being bound by, the
contract.
C) It automatically renders all contracts involving third-party interests void.
D) It requires all third parties to sign the contract document for it to be valid.
Correct Answer: B) It prevents a person who is not a party to the contract from enforcing,
or being bound by, the contract.
Explanation: Privity of contract dictates that only parties to a contract can sue or be sued under
it. Option A describes the outcome of the Contracts (Rights of Third Parties) Act 1999, which is
a statutory exception to the doctrine. Options C and D are legally incorrect.
Question 6: Which statement correctly identifies the legal status of an 'innominate term'?
A) It is a term that, if breached, automatically allows the innocent party to terminate the contract.
B) It is a term that only allows for damages and never allows for termination of the contract.
C) It is a term that can be classified as either a condition or a warranty based on the gravity of the
consequences of the breach.
D) It is a term implied by statute into every consumer contract.
Correct Answer: C) It is a term that can be classified as either a condition or a warranty
based on the gravity of the consequences of the breach.
Explanation: Following Hong Kong Fir Shipping, the innominate term approach requires the
court to examine the seriousness of the breach's consequences to determine the appropriate
remedy. Option A describes a condition, while Option B describes a warranty. Option D is
irrelevant to the definition of an innominate term.
Question 7: Under the Consumer Rights Act 2015, what is the 'short-term right to reject'?
A) The right to return goods within 14 days for any reason, including change of mind.
