Mr Gibson sought to purchase his council house under a scheme later abandoned by Manchester City Council following a change in political control. The House of Lords held that the council's letter stating they 'may be prepared to sell' did not constitute a legally binding offer capable of acceptance, being merely an invitation to apply.
Facts
Mr Gibson was a tenant of a council house owned by Manchester City Council. In 1970, the Conservative-controlled council adopted a scheme allowing tenants to purchase the freehold of their homes at market value less a discount based on length of tenancy. Mr Gibson expressed interest in purchasing his property at 174 Charlestown Road, Blackley.
On 10 February 1971, the City Treasurer wrote to Mr Gibson stating that ‘The Corporation may be prepared to sell the house to you at the purchase price of £2,725 less 20% = £2,180 (freehold)’. The letter invited Mr Gibson to ‘make formal application to buy’ using an enclosed form. The letter explicitly stated it ‘should not be regarded as a firm offer of a mortgage’.
Mr Gibson completed the application form, leaving the purchase price blank, and sent a covering letter on 5 March 1971 requesting either repairs to tarmac paths or a deduction from the purchase price. On 18 March 1971, after the council declined to make repairs, Mr Gibson wrote asking them to ‘carry on with the purchase as per my application’.
In May 1971, political control of the council changed to the Labour Party, and the house-selling scheme was suspended and later discontinued. Mr Gibson brought proceedings for specific performance, claiming a binding contract had been formed.
Issues
Primary Issue
Whether the correspondence between the parties, particularly the council’s letter of 10 February 1971, constituted a legally enforceable contract for the sale of the property.
Secondary Issue
Whether the conventional approach of identifying offer and acceptance should be applied, or whether the court should look at the correspondence as a whole to determine if agreement had been reached on all material terms.
Judgment
The House of Lords unanimously allowed the appeal, holding that no binding contract had been formed.
Lord Diplock, delivering the leading judgment, held that the conventional approach of looking for offer and acceptance should be applied. He found that the words ‘may be prepared to sell’ in the council’s letter were ‘fatal’ to construing it as a contractual offer. The letter was merely setting out financial terms on which the council might consider a sale, and invited Mr Gibson not to accept an offer but ‘to make formal application to buy’.
Lord Diplock rejected the approach taken by the majority in the Court of Appeal, which had looked at the correspondence as a whole and the conduct of the parties. He noted that referring to conduct where there was no allegation of part performance appeared to overlook section 40 of the Law of Property Act 1925.
Lord Edmund-Davies agreed that no offer had been made, stating there was ‘at best no more than an invitation by the corporation to tenants to apply to be allowed to purchase freeholds’. He also held that even if there had been an offer, Mr Gibson’s response was merely ‘an application to buy at an unstated price, coupled with an application for a loan’.
Lord Russell of Killowen stated that he could not accept that a letter saying the possible vendor ‘May be prepared to sell the house to you’ could be regarded as an offer to sell capable of acceptance.
Implications
This case reaffirmed the orthodox approach to contract formation, requiring clear identification of offer and acceptance in correspondence-based contracts. The House of Lords rejected the more flexible approach advocated by Lord Denning MR in the Court of Appeal, which sought to determine whether parties had reached agreement on all material terms regardless of whether a formal offer could be identified.
The case is significant for establishing that words indicating a willingness to negotiate, such as ‘may be prepared to sell’, do not constitute binding offers. Documents inviting applications to purchase are not the same as offers capable of acceptance. The decision also confirmed that where contracts are alleged to be formed by correspondence, the court should examine whether there was a genuine offer and acceptance rather than merely looking at whether the parties appeared to have reached consensus.
The case serves as an important precedent in distinguishing between preliminary negotiations and binding contractual offers, particularly in the context of sales of land subject to section 40 of the Law of Property Act 1925.
Verdict: Appeal allowed. The House of Lords discharged the Court of Appeal’s order, holding that no binding contract for the sale of the council house had been formed between the parties.
