Case Facts
The appellant placed an advertisement in the 13 April 1967 issue of Cage and Aviary Birds, a periodical for bird enthusiasts. The advertisement, which appeared under the general heading "Classified Advertisements", contained the words "Quality British ABCR … Bramblefinch cocks, Bramblefinch hens 25s each". Notably, the advertisement did not employ the words "offer for sale" anywhere on the page.
A reader named Thomas Shaw Thompson saw the advertisement and, on 22 April 1967, wrote to the appellant requesting an ABCR bramblefinch hen, enclosing a cheque for 30s. The appellant dispatched a hen on 1 May 1967. Thompson received the bird on 2 May 1967 in the presence of the respondent, Crittenden, who was acting on behalf of the RSPCA.
Upon arrival, the bird was wearing a closed ring, which Thompson was able to remove without causing any injury to the bird. The bird's condition was described as rough; it was extremely nervous, had no perching sense whatsoever, and its plumage was rough. From these observations, the justices inferred that the bird was not a close-ringed specimen bred in captivity.
The appellant was charged with unlawfully offering for sale a live wild bird — specifically a brambling (referred to in the advertisement as "Bramblefinch") — listed in Schedule 4 to the Protection of Birds Act 1954, being a species resident in or visiting the British Isles in a wild state, other than a close-ringed specimen bred in captivity, contrary to s 6(1)(a) of the Protection of Birds Act 1954.
The magistrates' court found that the advertisement constituted an offer for sale and convicted the appellant, fining him £5 and ordering payment of £5 5s in advocate's fees and £4 9s 6d in witnesses' expenses. The appellant appealed to the Queen's Bench Division by way of case stated.
Held
The Queen's Bench Division allowed the appeal. The court held that the advertisement placed in the classified section of the periodical constituted an invitation to treat in law, not an offer for sale. Accordingly, the offence charged under s 6(1)(a) of the Protection of Birds Act 1954 had not been established, because the appellant had never made an "offer for sale" within the meaning of the statute.
The court applied the principle established in Fisher v Bell [1961], in which it had been held that the display of a flick knife in a shop window with a price ticket attached constituted an invitation to treat and not an offer for sale. That same principle was applied directly to the classified advertisement in the present case.
The reasoning was that when a seller places an advertisement, they cannot be taken to have made a binding offer to every person who reads it and wishes to accept. The practical consequence is that the person who responds to the advertisement — here, Thompson, who wrote to the appellant enclosing a cheque — is the party making the offer, which the seller may then accept or decline. No offer for sale had therefore been made by the appellant, and the conviction could not stand.
Ratio Decidendi
The ratio of this case is that a classified advertisement in a periodical, which does not expressly constitute an offer for sale, amounts to an invitation to treat as a matter of law. The contract is formed only when a prospective buyer makes an offer in response to the advertisement and the seller accepts that offer. Consequently, the party who places a general advertisement addressed to the world at large is not making an offer; they are inviting offers from prospective purchasers.
This principle is consistent with the broader framework of English contract law, in which an invitation to treat marks the preliminary stage of negotiations rather than a binding contractual commitment. The distinction is particularly significant in criminal and regulatory contexts, such as the present case, where statutory liability was expressly tied to the act of "offering for sale". Since the advertisement was an invitation to treat and not an offer, the statutory offence could not be made out.
Obiter Dicta
The court made a significant observation per curiam regarding the second issue in the case — namely, whether the bird supplied was a close-ringed specimen bred in captivity within the meaning of Sch 4 to the Protection of Birds Act 1954. The court indicated that had the only issue before it been this question, the justices' inference from the evidence — that the bird was not a close-ringed specimen bred in captivity — would have been upheld by the High Court. The physical condition of the bird on arrival (its extreme nervousness, lack of perching sense, and rough plumage, together with the ease with which the ring was removed) provided a sufficient evidential basis for that finding. This observation did not form part of the ratio, as the appeal was decided on the invitation to treat point alone.
