Butler Machine Tool Co Ltd v Ex-Cell-O Corp (England) Ltd. [1977] EWCA Civ 9 (25 April 1977)

A 'battle of forms' dispute arose when sellers quoted a price with a price variation clause, but buyers placed an order on their own terms without such a clause. The sellers signed and returned the buyers' acknowledgement slip. The Court of Appeal held the contract was formed on the buyers' terms, establishing important principles for resolving conflicting standard form contracts.

Facts

On 23rd May 1969, Butler Machine Tool Co Ltd (sellers) quoted a price of £75,535 for a machine tool with delivery in 10 months. The quotation’s terms and conditions included a price variation clause allowing price increases based on costs at delivery date. On 27th May 1969, Ex-Cell-O Corporation (buyers) placed an order for the same machine at the same price but on their own terms and conditions, which did not include any price variation clause. The buyers’ order included a tear-off acknowledgement slip. On 5th June 1969, the sellers signed and returned this slip stating they accepted the order on the buyers’ terms and conditions. When delivery was delayed until November 1970, the sellers claimed an additional £2,892 under the price variation clause.

Issues

Primary Issue

On whose terms and conditions was the contract concluded – the sellers’ (which included the price variation clause) or the buyers’ (which did not)?

Secondary Issue

How should courts resolve ‘battle of forms’ disputes where parties exchange documents with conflicting standard terms?

Judgment

The Court of Appeal unanimously allowed the appeal and entered judgment for the buyers (defendants).

Lord Denning MR

Lord Denning applied the traditional offer and counter-offer analysis, finding that the sellers’ quotation was an offer, the buyers’ order was a counter-offer (rejecting and killing the original offer), and the sellers’ signed acknowledgement accepting the order on the buyers’ terms concluded the contract on those terms. He also discussed alternative approaches to battle of forms cases, noting that sometimes the battle is won by the party who fires the last shot, and that courts should look at all documents to glean whether agreement has been reached on material points.

Lawton LJ

Lawton LJ emphasised that the battle must be conducted according to set rules established since Hyde v Wrench. The buyers’ order, with materially different terms, killed the sellers’ quotation. The sellers then accepted the counter-offer by signing and returning the acknowledgement slip.

Bridge LJ

Bridge LJ noted this was a case plainly governed by the classical doctrine that a counter-offer amounts to rejection of an offer. The buyers’ order of 27th May was clearly a counter-offer that did not purport to accept the sellers’ terms. The sellers’ acknowledgement unambiguously stated they accepted the order on the buyers’ terms and conditions.

Implications

This case remains the leading English authority on the ‘battle of forms’. It confirms that traditional offer and counter-offer analysis generally applies, with the ‘last shot’ rule typically determining whose terms prevail. The case demonstrates the importance of carefully reviewing acknowledgement forms and the documents exchanged during contract formation. It highlights the risks of using standard form contracts without ensuring one’s own terms are clearly incorporated.

Verdict: Appeal allowed. Judgment entered for the defendants (buyers). The contract was concluded on the buyers' terms and conditions, which did not include a price variation clause. The sellers were not entitled to the additional £2,892 claimed.
