ESSAY

Title: The Distinction between Unilateral Offer, Bilateral Offer, and Invitation to Treat in the Formation of Contracts

Introduction

In order to establish the formation of a legally binding contract, it is crucial to distinguish between a unilateral offer, a bilateral offer, and an invitation to treat. This essay will discuss the significance of this distinction and the legal rules that govern it, as well as the implications of framing the law in this way.

Need for Offer and Acceptance

The fundamental requirement for the formation of a contract is the presence of an offer made by one party, and an acceptance of that offer by another party. This concept is deeply rooted in contract law, outlining the intentions of the parties to be legally bound by their agreement.

Distinguishing between Offer and Invitation to Treat

An offer is a clear indication of willingness to be bound by certain terms, whereas an invitation to treat is an invitation for offers or further negotiation. It is imperative to differentiate between the two in order to determine when a contract is actually formed.

Legal Rules to Clarify the Distinction

Advertisements are typically considered invitations to treat rather than offers, as seen in cases such as Partridge v Crittenden and Harris v Nickerson. Similarly, catalogue sales and price lists are also usually categorized as invitations to treat (Grainger & Sons v Gough).

However, advertisements can sometimes be construed as unilateral offers, as evidenced in cases like Carlill v Carbolic Smoke Ball Company and Bowerman v ABTA Ltd. The same principle applies to advertisements offering rewards, as demonstrated in Williams v Cawardine.

The display of goods in a shop window or on shelves in a self💥service store is generally treated as an invitation to treat, as established in Fisher v Bell and PSGB v Boots Cash Chemist Ltd. In these situations, the consumer is the party making the offer, which the retailer can choose to accept or reject.

Importance of Framing the Law in This Way

The distinction between offers and invitations to treat serves several crucial purposes:

1. Upholding Freedom of Contract: It allows sellers the freedom to choose with whom they wish to contract, protecting them from being compelled to sell to undesirable customers such as trade rivals.

2. Avoiding Commercial Chaos: If shop displays were deemed as offers, businesses would face immense pressure to maintain high levels of stock or risk facing legal action for breach of contract due to insufficient supply.

3. Preventing Mass Liability: Treating every advertisement as an offer would expose advertisers to potential breach of contract claims from countless individuals who responded to the advertisement.

4. Facilitating Negotiation: Recognizing invitations to treat encourages negotiation between buyers and sellers, promoting a fair and balanced bargaining process.

Conclusion

In conclusion, the distinction between unilateral offers, bilateral offers, and invitations to treat plays a pivotal role in contract formation, ensuring clarity and fairness in commercial transactions. By understanding and applying the legal rules governing these concepts, parties can navigate contract negotiations effectively and uphold the principles of freedom of contract and mutual agreement.

NOTES

When goods are advertised for sale or displayed in stores, it is essential to distinguish between a unilateral offer, a bilateral offer, and an invitation to treat in order to establish when any contract is made. Discuss the extent to which the statement above is true. Candidates may begin by stating the need for offer and corresponding acceptance for a contract to exist. The need, therefore, to distinguish between an offer and invitation to treat should be explained. Candidates should explain the legal rules to clarify the distinction and Explain appropriate terms.

Advertisements are generally regarded as being an invitation to treat because they suggest further negotiation between advertiser and customer before a bilateral contract results (Partridge v Crittenden, Harris v Nickerson). A similar principle applies to catalogue sales and price lists (Grainger & Sons v Gough). This rule can be displaced, however, if the advertisement is regarded as a unilateral offer (which form unilateral contracts). In effect, the offerer promises to pay for the act of another (Carlill v Carbolic Smoke Ball Company, Bowerman v ABTA Ltd). Similar principles apply to advertisements offering rewards (Williams v Cawardine).

Display of goods in a shop window or on shelves in a self💥service store is an invitation to treat (Fisher v Bell, PSGB v Boots Cash Chemist Ltd). In these instances, the consumer makes the offer which the retailer can accept or reject. Candidates should then discuss why the framing of the law in this way is essential. For example:

💥 It reflects the idea of freedom of contract, allowing the seller to refuse to sell an item to a particular customer, e.g., a trade rival.
💥 The distinction avoids commercial chaos, e.g., if a shop display was an offer stores would have to keep a lot of stock or risk being sued if they could not satisfy demand.
💥 If every advertisement was an offer, then the person who placed the advertisement would be liable for breach of contract to every person who answered willing to proceed on the terms stated.
💥 Agreement will rarely be instantaneous. It is only fair that buyer and seller should be allowed to negotiate a deal. As Winfield (1939) states ‘A shop is a place for bargaining and not compulsory sales’.
