Introduction
This essay examines a contractual dispute between Seller Ltd and Buyer Ltd under English contract law, focusing on the formation of a contract, the effectiveness of acceptance, and the attempted revocation by Buyer. The scenario involves a series of communications—fax offers, posted acceptances, and a faxed revocation—complicated by timing and technical issues. Key issues to be addressed include whether a contract was formed, the applicability of the postal rule, and whether Buyer’s attempt to countermand the order was legally effective. This analysis will draw on established legal principles and case law to evaluate the rights and obligations of both parties, providing a foundation for understanding contract formation and communication in commercial transactions.
Formation of Contract and the Postal Rule
Under English law, a contract is formed when there is an offer, acceptance, consideration, and an intention to create legal relations (Adams, 2010). In this case, Seller Ltd makes a clear offer on Monday to sell 1,000 widgets for £10,000, open until 5 pm on Friday. Buyer Ltd posts a letter of acceptance on Tuesday, which, under the postal rule, is generally deemed effective at the moment of posting, provided the letter is properly addressed and stamped (Adams v Lindsell, 1818). Indeed, this rule, established in the early 19th century, protects the acceptor by considering the contract formed even before the offeror receives the acceptance (Treitel, 2015). Here, the letter was posted on Tuesday, likely creating a binding contract at that point, assuming no issues with postage. The fact that Seller reads the letter only on Wednesday at 2 pm does not alter this, as the postal rule focuses on the act of sending rather than receipt.
Effectiveness of Buyer’s Revocation Attempt
On Wednesday morning, upon learning of the Dutch company’s financial difficulties, Buyer faxes a message countermanding the order. However, the fax is received into memory on Seller’s machine, which is out of paper, and Seller only becomes aware of it on Thursday. A critical question arises: is the revocation effective before Seller reads it? Generally, for communication of revocation to be valid, it must be received by the other party (Byrne & Co v Leon Van Tienhoven, 1880). Unlike acceptance under the postal rule, revocation typically requires actual communication. Arguably, the fax being stored in memory might not constitute receipt until Seller is aware of it, as effective communication implies the recipient has the opportunity to access the message (Treitel, 2015). Therefore, the revocation is likely ineffective until Thursday, by which time the contract is arguably already binding due to the earlier acceptance.
Impact of Seller’s Actions with Tertius Ltd
At 3 pm on Wednesday, Seller declines an offer from Tertius Ltd for £11,000, citing insufficient stock, seemingly relying on the contract with Buyer. This action suggests Seller considered the contract with Buyer as binding after reading the acceptance letter at 2 pm. This reinforces the position that a contract was formed, as Seller acted in a manner consistent with a contractual obligation. However, if the court were to find that no contract existed due to some failure in acceptance or effective communication, Seller might face losses for rejecting Tertius Ltd’s higher offer, highlighting the practical implications of contractual uncertainty (Adams, 2010).
Conclusion
In conclusion, under English contract law, a binding contract was likely formed between Seller Ltd and Buyer Ltd when the acceptance letter was posted on Tuesday, as per the postal rule. Buyer’s attempt to revoke via fax on Wednesday was arguably ineffective, as Seller did not receive it until Thursday, after the contract was already in place. Furthermore, Seller’s rejection of Tertius Ltd’s offer demonstrates reliance on the contract with Buyer, strengthening the argument for a binding agreement. This case underscores the importance of clear communication and timing in contract law, as well as the enduring relevance of rules like the postal rule in modern commercial contexts. The implications for Buyer are significant, as they may be obliged to proceed with the purchase despite their changed circumstances, illustrating the challenges of balancing legal principles with practical business needs.
