Introduction
This essay examines a hypothetical scenario involving Apricot Ltd.’s sale of limited-edition ‘MockBook’ laptops, focusing on potential contractual claims by three individuals: Rose, Josey, and Dane. Under English common law, which governs contract formation in the UK, key principles such as offer and acceptance, mistake, authority, and intention to create legal relations will be analysed to advise on any enforceable agreements. The scenario highlights issues arising from advertisements on Google AdWords and Facebook, a pricing error in the latter, and subsequent actions including the university sale. The purpose is to assess whether contracts were formed with each party, considering remedies like damages, rescission, specific performance, or injunctions. This analysis draws on established case law and academic sources to provide sound advice, acknowledging limitations where evidence is ambiguous. The essay will proceed by evaluating the advertisements’ legal status, then advising each individual, before discussing remedies and concluding on implications.
The Legal Nature of the Advertisements: Offer or Invitation to Treat?
In contract law, distinguishing between an offer and an invitation to treat is crucial, as only an offer can be accepted to form a binding agreement (Elliott and Quinn, 2019). Advertisements are generally considered invitations to treat, not offers, unless they contain specific terms that indicate a willingness to be bound. For instance, in Partridge v Crittenden [1968] 1 WLR 1204, a newspaper advert for protected birds was deemed an invitation to treat, not an offer for sale. However, exceptions exist where adverts promise unilateral contracts, as in Carlill v Carbolic Smoke Ball Co [1893] 1 QB 256, where a reward for using a product constituted an offer accepted by performance.
Applying this to Apricot’s Google AdWords advertisement, it promotes a sale at Middlesex University with discounted prices, including MockBooks at £5,000. This appears as an invitation to treat, inviting potential buyers to attend and purchase, rather than a direct offer. The charitable context and phrase “Come early not to miss out!” suggest limited stock, but do not promise sales to all attendees, aligning with cases like Pharmaceutical Society of Great Britain v Boots Cash Chemists [1953] 1 QB 401, where shop displays are invitations to treat.
Conversely, the Facebook advertisement states: “The first two who reply can buy a MockBook laptop for 50% off! £500 instead of £10,000.” This seems more like a unilateral offer, promising a discount to the first two responders, akin to Carlill. However, a typographical error listed £500 instead of £5,000, corrected shortly after. This introduces the doctrine of mistake, particularly unilateral mistake, where one party errs but the other is unaware (Hartog v Colin & Shields [1939] 3 All ER 566). Intention to create legal relations is presumed in commercial contexts (Edwards v Skyways Ltd [1964] 1 WLR 349), but the error and limited stock (only ten laptops) complicate matters. Furthermore, Apricot authorised Middlesex University to conduct the sale, raising agency issues under apparent authority principles (Freeman & Lockyer v Buckhurst Park Properties [1964] 2 QB 480).
Advising Rose: Potential Contract and the Impact of Mistake
Rose responded first to the Facebook advert, offering to buy two MockBooks at £500 each, then transferred £1,000 without noticing the correction. She treated the advert as an offer and her reply as acceptance. However, advertisements are typically invitations to treat, so Rose’s reply might be seen as an offer, which Apricot could accept or reject. Apricot ignored her due to the low price, suggesting no acceptance. In common law, acceptance must be communicated unless waived, as in Felthouse v Bindley (1862) 11 CBNS 869, where silence does not constitute acceptance.
The pricing mistake is key. If the advert was an offer, Rose’s acceptance before correction could bind Apricot, but unilateral mistake allows rescission if the non-mistaken party knew or should have known of the error (Smith v Hughes (1871) LR 6 QB 597). Rose, unaware of the amendment, arguably acted in good faith, but the drastic discount (£500 vs £10,000) might indicate she should have suspected an error, potentially voiding any contract for mistake. Regarding intention, the commercial and charitable elements suggest presumptive intent, but Apricot’s ignorance implies none.
If no contract exists, Rose might claim unjust enrichment for her £1,000 transfer, seeking restitution. Equitable remedies like specific performance are unlikely for unique goods already sold, as courts prefer damages (typically, expectation damages under Robinson v Harman (1848) 1 Ex 850). However, with laptops sold, damages could cover her loss, though limited by remoteness (Hadley v Baxendale (1854) 9 Ex 341). Rose’s position is weak; she has no strong claim for breach, but might recover her payment.
Advising Josey: Quantity Issues and Conditional Offers
Josey, the second responder, requested 11 laptops after noticing the correction, offering £55,000 at £5,000 each. He positioned himself as the second respondent, but Apricot ignored him because only ten units existed. If the Facebook advert was a unilateral offer to the first two, Josey’s reply could be acceptance, but his request for 11 exceeds availability, potentially making it a counter-offer (Hyde v Wrench (1840) 49 ER 132). Moreover, the advert specified “a MockBook laptop” (singular), implying one per person, though ambiguous.
Authority is relevant: Apricot authorised the university sale but attempted revocation via voicemail, unchecked until after the event. This raises apparent authority; the student ambassador sold the laptops, binding Apricot if the authority appeared valid (Freeman & Lockyer). Josey’s message requested bank details, indicating his communication was an offer needing acceptance, which Apricot did not provide. Silence here does not equate to acceptance, per Felthouse.
Intention to create relations exists commercially, but no mutual assent occurred. Josey might argue promissory estoppel if he relied detrimentally (e.g., pre-orders), as in Central London Property Trust Ltd v High Trees House Ltd [1947] KB 130, but evidence of reliance is thin. Remedies: Specific performance for 10 laptops could be sought if a contract formed, but with goods sold, injunctions are impractical. Damages for lost profits from his 11 customers might be available, though capped by foreseeability. Overall, Josey’s claim is tenuous due to the quantity mismatch and lack of acceptance.
Advising Dane: Silence, Conditional Offers, and Revocation
Dane, the third responder, offered full price (£100,000) for 10 laptops conditionally if the first two failed, assuming acceptance by silence if no response by tomorrow. Apricot internally decided to accept but did not communicate, instead attempting to cancel the university sale. Common law requires communicated acceptance; silence is insufficient (Felthouse), even if Dane stipulated it. Thus, no contract formed, despite Apricot’s belief that communication was unnecessary at retail price.
The offer was conditional and alternative, resembling an option contract, but without consideration, it is revocable. Intention is present, but lack of acceptance undermines it. The university’s sale proceeded under actual authority, not effectively revoked by the unanswered voicemail, potentially binding Apricot. Dane might claim breach if a contract existed, seeking specific performance for the unique signed laptops, as equity may order delivery of specific goods (Sky Petroleum Ltd v VIP Petroleum Ltd [1974] 1 WLR 576). However, without formation, damages are unavailable. Equitable remedies like injunctions to prevent further sales are moot post-sale.
Remedies and the Pricing Mistake in Context
Across all cases, the £500 vs £5,000 mistake affects Rose most directly. Courts may rectify unilateral mistakes if inequitable to enforce (Solle v Butcher [1950] 1 KB 671), potentially allowing rescission. For all, if contracts formed, expectation damages apply, but the charitable intent and limited stock limit availability. Equitable remedies are discretionary and rare for mass-produced goods, though the signed laptops’ uniqueness argues for specific performance. However, the university’s third-party sale complicates this, invoking bona fide purchaser protections.
Conclusion
In summary, none of Rose, Josey, or Dane likely formed enforceable contracts with Apricot due to issues in offer and acceptance, compounded by mistake and ineffective communication. Rose may recover her payment via restitution, while Josey and Dane have weaker positions lacking acceptance. The scenario underscores the pitfalls of online advertisements and agency in contract law, highlighting the need for clear communication. Implications include potential reforms for digital contracts, ensuring errors do not unjustly bind parties. Ultimately, common law prioritises mutual agreement, leaving these individuals with limited recourse.
