LORD JUSTICE SOMER VELL: We need not trouble you, Mr Baker.
LORD JUSTICE SOMER VELL: This is an appeal from the Lord Chief Justice on a Case Stated on
an agreed statement of facts raising a question under section 18(1)(a)(iii) of the Pharmacy and Poisons
Act, 1933. The Plaintiffs are the Pharmaceutical Society who were incorporated by Royal Charter. One
of their duties is to take all reasonable steps to enforce the provisions of the Act. The provision in
question is:
"Subject to the provisions of this part of this Act it shall not be lawful for a
person to sell any poison included in Part I of the Poisons List, unless ...... (iii)
the sale is effected by, or under the supervision of, a registered pharmacist".
The Defendants, Messrs Boots Cash Chemists (Southern) Limited have recently introduced into one or
more of their premises what is called a self-service system. We have a number of photographs and one
can see a number of articles such as toilet articles, laxatives, ointments and tonics, the kind of articles
which one normally finds in one of Messrs Boots' shops, laid out on shelves. The customer when he
comes in is invited to take a receptacle and goes round and can choose the articles which he wants. He
then goes to one of two desks at the end of the room, and there, admittedly, there is a registered
pharmacist, able to carry out, subject to the point which I will mention in a moment, such duties as are
involved in his position. It is not disputed that in a chemist's shop where this system does not prevail a
man may go in and ask a young lady, who will not herself be a registered pharmacist, for one of these
articles on the List and the transaction may be completed and the article paid for, although the
registered pharmacist, who will no doubt be on the premises, will not know anything himself of the
transaction unless the assistant serving the customer, or the customer, requires to put a question to him.
It is right that I should emphasise, as the Lord Chief Justice did, that these are not dangerous drugs.
They are things which contain very small proportions of poison and I imagine many of them are the
type of drug which has a warning as to what doses are to be taken. They are drugs which can be
obtained under the law without a doctor's prescription.
The point which is taken by the Plaintiffs is this: It is said that the purchase is complete if and when a
customer going round the shelves takes an article and puts it in the receptacle which he or she is
carrying, and therefore if that is right when the customer cornea to the pay desk, having completed the
tour of the premises, the registered pharmacist, if so minded, has no power to say: "This drug ought not
to be sold to this customer". Whether and in what circumstances he would have that power we need not
enquire, but one can, of course, see that there is a difference if supervision can only be exercised at a
time when the contract is completed.
I agree with the Lord Chief Justice in everything he says, but I will put it shortly in my own words.
Whether that is a right view depends on what are the legal implications of this layout, the invitation to
the customer. Is it to be regarded as an offer which is completed and both sides bound when the article
is put into the receptacle, or is it to be regarded as a more organised way of doing what is done already
in many types of shops — and a bookseller is perhaps the beat example - namely, enabling customers
to have free access to what is in the shop to look at the different articles and then, ultimately, having
got the ones which they wish to buy, coming up to the assistant and saying "I want this"? The assistant
in 999 times out of 1,000 says "That is all right", and the money passes and the transaction is
completed. I agree entirely with what the Lord Chief Justice says and the reasons he gives for his
conclusion that in the case of the ordinary shop, although goods are displayed and it is intended that
customers should go and choose what they want, the contract is not completed until, the customer
having indicated the articles which he needs, the shop-keeper or someone on his behalf accepts that
offer. Then the contract is completed. I can see no reason at all, that being I think clearly the normal
position, for drawing any different implication as a result of this layout. The Lord Chief Justice, I think,
expressed one of the most formidable difficulties in the way of the suggestion when he pointed out that,
if the Plaintiffs are right, once an article has been placed in the receptacle the customer himself is
bound and he would have no right without paying for the first article to substitute an article which he
saw later of the same kind and which he perhaps preferred. I can see no reason for implying from this
arrangement which the Defendants have referred to any implication other than that which the Lord
Chief Justice found in it, namely, that it is a convenient method of enabling customers to see what there
is and choose and possibly put back and substitute articles which they wish to have and then go up to
the cashier and offer to buy what they have so far chosen. On that conclusion the case fails, because it
is admitted that then there was supervision in the sense required by the Act and at the appropriate
moment of time. For these reasons, in my opinion, the appeal should be dismissed.
LORD JUSTICE BIRKETT : I am of the same opinion. The facts with which we have to deal are
very clearly stated in the agreed statement of facts. The argument upon those facts has been very
clearly stated by Mr Lloyd-Jones. I think clearest of all was the Judgment of the Lord Chief Justice,
with which I agree. In view of something which I said while the argument was proceeding, I should
like to add that under section 25 of the Pharmacy and Poisons Act, 1933, it is the duty of the
Pharmaceutical Society of Great Britain, by means of inspection and otherwise, "to take all reasonable
steps to enforce the provisions of Part I of this Act" — that really deals with the status of the registered
pharmacist — "and to secure compliance by registered pharmacists and authorised sellers of poisons
with the provisions of Part II of this Act Part II of the Act, which is headed "Poisons" in section 18(1)
(a)(iii), says
"it shall not be lawful for a person to sell any poison included in Part I of the
Poisons List, unless (i) he is an authorised seller of poisons; and .... (iii) the
sale is effected by, or under the supervision of, a registered pharmacist".
This action has been brought by the Pharmaceutical Society in pursuance of that duty which is laid
upon them by statute, and the precise point is set out in the subsection which I have read. The short
point of the matter was, at what point of time did the sale in this particular shop at Edgware take place?
My Lord has explained the system which has been introduced into that shop (and possibly other shops
since) in March of 1951. The two ladles in this case. Miss Mainwaring and Miss Marrable, who went
into that shop, each took a particular package containing poison from the particular shelf, put it into
their basket, came to the exit and there paid. It is said upon the one hand that when the customer takes
the package from the poison section and puts it into her basket the sale there and then takes place, On
the other hand, it is said the sale does not take place until that customer who has placed that package in
the basket comes to the exit.
The Lord Chief Justice dealt with the matter in this way, and I would like to adopt these words:
"It seems to me therefore, applying common sense to this class of transaction,
there is no difference merely because a self-service is advertised. It is no
different really from the normal transaction in a shop. I am quite satisfied it
would be wrong to say the shopkeeper is making an offer to sell every article
in the shop to any person who might come in and that he can insist by saying
'I accept your offer'".
Then he goes on to deal with the illustration of the bookshop and continues:
"Therefore, in my opinion, the mere fact that a customer picks up a bottle of
medicine from the shelves in this case does not amount to an acceptance of an
offer to sell. It is an offer by the customer to buy. I daresay this case is one of
great importance, it is quite a proper case for the Pharmaceutical Society to
bring, but I think I am bound to say in this case the sale was made under the
supervision of a pharmacist. By using the words 'The sale is effected by, or
under the supervision of, a registered pharmacist', it seems to me the sale
might be effected by somebody not a pharmacist. If it be under the
supervision of a pharmacist, the pharmacist can say 'You cannot have that.
That contains poison'. In this case I decide, first that there is no sale ef fected
merely by the purchaser taking up the article. There is no sale until the buyer's
offer to buy is accepted by the acceptance of the money, and that takes place
under the supervision of a pharmacist. And in any case, I think, even if I am
wrong in the view I have taken of when the offer is accepted, the sale is by or
under the supervision of a pharmacist".
I agree with that and I agree that this appeal ought to be dismissed.
LORD JUSTICE ROMER : I also agree. The Lord Chief Justice observed that, on the footing of the
Plaintiff Society's contention, if a person picked up an article, once having picked it up, he would never
be able to put it back and say he had changed his mind. The shopkeeper would say: "No, the property
has passed and you will have to pay". If that were the position in this shop and similar shops, and that
position was known to the general public, I should imagine the popularity of those shops would wane a
good deal. In fact, I am satisfied that that is not the position and that the articles, even though they are
priced and put in shops like this, do not represent an offer by the shopkeeper which can be accepted
merely by the picking up of the article in question. I quite agree with the reasons on which the Lord
Chief Justice arrived at that conclusion and which my brother Birkett has just referred to, and to those
observations I can add nothing of my own I agree that the appeal fails.

The distinction between an invitation to treat and a formal offer is a cornerstone of contract law, a principle expertly clarified in the landmark case of Pharmaceutical Society of Great Britain v Boots Cash Chemists (Southern) Ltd. [1953]. This pivotal ruling on offer and acceptance remains a foundational element of legal education and practice, and its full judgment is authoritatively documented on CaseOn. The case addressed a novel issue for its time: in the new world of self-service shopping, at what exact moment is a contract of sale formed?
The central legal question before the England and Wales Court of Appeal was to determine the precise point of sale in a self-service pharmacy. Was the contract concluded when a customer took an item from the shelf and placed it in their basket, or was it when they presented the item to the cashier and paid for it? The answer was critical, as it would determine whether Boots Cash Chemists had violated a key piece of legislation.
The case hinged on two main legal concepts: the principles of offer and acceptance in contract law, and the specific requirements of the Pharmacy and Poisons Act, 1933. Section 18 of this Act made it unlawful to sell certain listed poisons unless the sale was “effected by, or under the supervision of, a registered pharmacist.” Additionally, the court had to consider the established common law distinction between a binding offer and a non-binding invitation to treat—an invitation for customers to make an offer.
The court meticulously examined the mechanics of the self-service system to apply these legal principles. The arguments presented by both sides revealed two fundamentally different interpretations of the transaction.
The Society argued that the display of goods on the shelves was a formal offer to sell. Consequently, they contended that a customer accepted this offer the moment they selected an item and placed it in their shopping basket. If this were true, the sale would be completed at that point—away from the cash desk and without the legally required supervision of a pharmacist, thus constituting an illegal act.
Boots countered that the display of goods was not an offer but merely an invitation to treat. They proposed that the customer was the one who made the offer to buy when they brought their chosen items to the cash desk. The shop, represented by the cashier (acting under the pharmacist's supervision), was then free to accept or reject this offer. Under this interpretation, the sale was only completed at the till, fully satisfying the supervision requirements of the Act.
The Court of Appeal unanimously sided with Boots, upholding the initial judgment. Lord Justice Somervell pointed out a critical flaw in the Society's logic: if taking an item from the shelf constituted acceptance, the customer would be legally bound to purchase it and could not simply change their mind and put it back. This, he noted, would be an absurd and impractical outcome.
The court concluded that the self-service model was simply a more convenient way of shopping, not a fundamental change in the legal nature of the transaction. The display is an invitation, the customer makes the offer at the checkout, and the cashier accepts it, finalizing the contract. This critical moment of acceptance occurs under the direct supervision of the on-site pharmacist, who retains the authority to intervene and refuse a sale if necessary. For legal professionals looking to quickly grasp the nuances of such landmark rulings, CaseOn’s 2-minute audio briefs provide a concise analysis of judgments like this one, breaking down complex reasoning into accessible insights.
The appeal was dismissed. The court firmly established that in a self-service environment, the display of goods is an invitation to treat. The contract of sale is formed at the cash desk when the shop accepts the customer's offer to buy. Therefore, Boots' self-service system did not contravene the Pharmacy and Poisons Act, 1933, as the sale was supervised by a registered pharmacist at the proper time.
The Court of Appeal (Civil Division), with Lord Justices Somervell, Birkett, and Romer presiding, affirmed the decision of the Lord Chief Justice. They found that the self-service system implemented by Boots Cash Chemists did not violate Section 18 of the Pharmacy and Poisons Act, 1933. The court held that the display of items on shelves was an invitation to treat, not an offer. The customer makes an offer to purchase at the checkout, which is then accepted by the cashier. This acceptance, and thus the completion of the sale, occurs under the supervision of a registered pharmacist, satisfying the statutory requirement.
This case is essential reading for anyone studying contract law. It provides the definitive legal precedent for transactions in retail and commercial settings, from supermarkets to e-commerce websites where items are displayed in a 'virtual basket'. It masterfully clarifies the practical difference between an offer and an invitation to treat, a concept that is fundamental to understanding when a legally binding agreement comes into existence. The judgment's logical, common-sense approach makes complex legal theory accessible and demonstrates how the law adapts to new commercial practices.
