Case Law Jigsaw

Divide students into 'expert' groups, each assigned a key case on offer or invitation to treat (e.g., Fisher v Bell, Carlill v Carbolic Smoke Ball Co). After researching the facts and legal principle, students are reorganised into new groups with one 'expert' from each original case to teach their findings to their new peers.

Explain the difference between an offer and an invitation to treat, using case law examples.

Facilitation Tip

Provide a structured note-taking sheet to guide the expert research and subsequent peer teaching.

What to look for

Present students with a series of mini-scenarios on slides. For each, they must hold up a card indicating 'Offer', 'Invitation to Treat', 'Acceptance', or 'No Contract' to quickly check understanding.

• Case Study Analysis
• 30 min · Small Groups

Contract Formation Role-Play

Students work in small groups to script and perform short scenarios involving everyday transactions like an auction, a supermarket shop, or an online purchase. The rest of the class must identify the invitation to treat, the offer, and the point of acceptance.

Analyse the rules relating to the communication of acceptance.

Facilitation Tip

Pause after each role-play to facilitate a whole-class discussion and clarify the legal analysis.

What to look for

A timed essay based on a problem question. The scenario will involve a series of communications between parties, requiring students to advise on whether a contract was formed, applying relevant case law.

Activity 03

• Case Study Analysis
• 50 min · Whole Class

The Postal Rule on Trial

Hold a structured class debate on the motion: 'The postal rule is no longer fit for purpose in the digital age and should be abolished'. Students must use case law and logical reasoning to argue for or against the motion.

Evaluate the impact of modern communication methods, such as email, on the traditional postal rule.

Facilitation Tip

Assign specific roles (e.g., opening argument, rebuttal) to ensure broad participation.

What to look for

Students swap written answers to a short problem question and mark them against a simplified mark scheme, providing feedback on the use of case law and application of legal principles.

• Analyze
• Evaluate
• Create
• Decision-Making
• Self-Management

A few notes on teaching this unit

Begin by grounding the concepts in simple, relatable examples before introducing the formal case law. Use visual aids like flowcharts to help students navigate the distinction between an offer and an invitation to treat. Emphasise the 'mirror image' rule for acceptance, ensuring students understand that any deviation creates a counter-offer.

By the end of this topic, your students will be able to dissect everyday situations, from online shopping to public advertisements, and apply legal tests to determine if a contract exists.

Watch Out for These Misconceptions

• An advertisement to sell something is always a legally binding offer.

  Generally, an advertisement is considered an 'invitation to treat', which invites potential customers to make an offer. This is established in cases like *Partridge v Crittenden*. Only in rare cases, where the advert contains a very specific promise and shows clear intent (like in *Carlill v Carbolic Smoke Ball Co*), can it be a unilateral offer.

• If you don't reply to an offer, your silence can be taken as acceptance.

  Acceptance must be actively communicated to the offeror. The case of *Felthouse v Bindley* established that silence cannot be imposed as a means of acceptance, as it would be unfair to bind someone to a contract they have not actively agreed to.

• A contract is formed as soon as I send an email accepting an offer.

  This is complex. While the postal rule states acceptance occurs on posting, it generally does not apply to instantaneous communication like email. The receipt rule from *Entores* is usually applied, meaning acceptance occurs when the email arrives in the offeror's inbox during business hours, though the law here is still developing (*Thomas v BPE Solicitors*).
