Manchester Diocesan Council for Education v Commercial and General Investments Ltd [1970] 1 WLR 241

📌 Facts

The Manchester Diocesan Council for Education invited tenders for the sale of school premises. The tender form stated that acceptance would be communicated by letter to the address provided by the successful tenderer.

Commercial and General Investments Ltd submitted the highest tender of £28,500. The Council’s surveyor later informed the company’s surveyor that the tender had been approved, although formal approval from the Secretary of State was still required.

The acceptance was not sent to the address specified in the tender form (but rather to the company's surveyor). The company therefore argued that no binding contract had been formed because the prescribed method of acceptance had not been followed. The Council sought a declaration that a contract existed and an order for specific performance.

📌 Issue

The issue was whether the Council had validly accepted the company’s tender despite failing to use the precise method of acceptance described in the tender form. The court therefore had to determine whether the stated method was compulsory or whether an equally effective method of communicating acceptance was sufficient.

📌 Decision

The Court held that a binding contract had been formed. Although the tender stated that acceptance would be communicated by a letter sent to the address provided by the tenderer, it did not clearly state that this was the only valid method of acceptance. The Council’s acceptance, communicated through the company’s surveyor, was therefore effective.

Buckley J stated:

“Where the offeror has prescribed a particular method of acceptance, but not in terms insisting that only acceptance in that mode shall be binding…”

📌 Analysis

The case is a leading authority on prescribed methods of acceptance.

It established that:

• an offeror may state a particular method by which an offer should be accepted;

• that method is only mandatory where the offer clearly states that no other method will be valid;

• where the method is merely suggested, another equally effective method may be used; and

• the alternative method must be no less advantageous to the offeror.

The decision prevents a valid acceptance from failing merely because the offeree has made a minor departure from the method suggested by the offeror.

Suggested and Mandatory Methods

The wording of the offer must be examined carefully.

For example, where an offer asks for acceptance “by post,” this may merely suggest an appropriate method. Acceptance through an equally effective or quicker method may still be valid.

By contrast, where the offer states that acceptance “must be received by signed letter at the stated address and no other method will be accepted,” the prescribed method is likely to be mandatory. The offeror must therefore make any exclusivity requirement clear.

Commercial Practicality

The decision reflects a practical approach to contract formation. The purpose of communicating acceptance is to ensure that the offeror knows that the offer has been accepted. Where an alternative method achieves that purpose without placing the offeror at a disadvantage, it would be overly technical to deny the existence of a contract solely because the precise procedure was not followed.
