An auction is a public sale to the highest of competing bidders. Section 64 of the Sale of Goods Act, 1930 collects six rules — six sub-clauses — that turn the special procedure of an auction into a tractable contract of sale. The fall of the hammer is the moment of acceptance; each lot is presumed to be a separate contract; reserve prices may be expressly notified; the seller may not bid pretending to be a stranger unless he has reserved the right; and certain pretended-bidding tactics are declared fraudulent. The chapter turns on the section text itself, but the doctrine has a rich case-law texture going back to Payne v. Cave (1789).
Auction sales are an evergreen examination favourite. The reason is structural: the offer-and-acceptance machinery of the Indian Contract Act runs in unusual directions in an auction, and Section 64 is the only place in the SoGA that interferes directly with the formation of a sale contract. Read together with the Sale of Goods Act notes hub and the contract-of-sale chapter, the section also presupposes the offer-and-acceptance basics from the Indian Contract Act.
What is an "auction sale"?
An auction sale is a sale by competitive bidding conducted in the open or in a defined arena. The seller — or, more usually, an auctioneer acting on the seller's behalf — invites successive bids and accepts the highest. The auctioneer, although usually employed by the seller, is treated by law as a special kind of mercantile agent: he holds possession of the goods for the purpose of sale, his authority is governed by the contract with the seller, and a buyer at the auction is entitled to take a clean title from him under the rules in Sections 27 to 30 of the Sale of Goods Act.
An auction is therefore not a single contract but a structured negotiation. The notice of auction is an invitation to treat; each bid is an offer; the fall of the hammer is the seller's acceptance. This three-stage analysis is settled in Payne v. Cave (1789) 3 Term Rep 148 and forms the bedrock of Section 64.
Statutory anchor — Section 64 of the SoGA
Section 64 sets out, in six sub-clauses, the special rules that apply to a sale of goods by auction. The structure is as follows:
- Each lot is prima facie the subject-matter of a separate contract.
- The sale is complete when the auctioneer announces its completion by the fall of the hammer or in some other customary manner.
- Until announcement of completion, any bidder may retract his bid.
- The seller's right of bidding must be expressly reserved; otherwise it is unlawful for the seller to bid himself or to employ any person to bid on his behalf.
- The auction may be conducted subject to a notified reserve or upset price.
- If the seller makes use of pretended bidding to raise the price, the sale is voidable at the option of the buyer.
Each sub-clause is independent, and the cluster is to be read in the light of the general law of contract — invitation, offer, acceptance, withdrawal of offer — supplied by the Indian Contract Act. The sub-clauses are best handled one at a time.
Section 64(1) — each lot is a separate contract
The auctioneer typically arranges goods into lots. The first sub-clause says, in terms, that where goods are put up for sale in lots, each lot is prima facie the subject of a separate contract of sale. The doctrinal consequences are not trivial.
- A defect or breach in respect of one lot does not, by itself, infect any other.
- A bid for one lot does not bind the bidder to bid for, or accept, any other lot.
- The passing of property analysis under Sections 18 to 25 proceeds lot-by-lot — each lot must be ascertained and in a deliverable state for property in that lot to pass.
- Risk and remedies similarly attach lot-by-lot.
The presumption is rebuttable. The seller may, by clear announcement before the auction begins, group lots into a single contract — for example, where a complete library is being sold and the seller wishes to insist that all volumes be taken together. Absent such an announcement, the default is one lot, one contract.
Section 64(2) — completion by the fall of the hammer
The second sub-clause is the most-cited line in the section. The sale is complete when the auctioneer announces its completion — typically by the fall of the hammer, but any other customary manner (a wave of the hand, a cry of "sold") will do where the trade so accepts. Until that moment, the highest bid is only an offer; only the auctioneer's acceptance, communicated by the customary signal, binds the parties.
The leading authority is Payne v. Cave (1789), where the highest bidder withdrew his bid before the fall of the hammer. The court held that no contract had yet been formed: a bid is an offer that may be retracted at any time before acceptance, and the auctioneer's acceptance is signified only by the fall of the hammer or its equivalent. The same logic supports Section 64(3), considered next.
The Indian application of this rule produced the well-known decision in Dennant v. Skinner (1948) 2 KB 164. There a car was sold by auction; the buyer paid by cheque on the auctioneer's signature of a document which purported to keep property in the seller until the cheque was cleared. The cheque bounced, and the buyer onward-sold the car. The court held that the contract was complete at the fall of the hammer — at which point the property in the specific, deliverable goods passed to the buyer under Section 20 of the Act. The post-hammer document could not unmake what the hammer had made.
Section 64(3) — retraction of the bid before acceptance
The third sub-clause is the natural corollary of the second. A bidder may retract his bid at any time before the auctioneer announces completion. The bid is a unilateral offer, and offers are revocable at common law and under Section 5 of the Indian Contract Act until they are accepted. Payne v. Cave is again the textbook example.
The right of retraction applies only to the bidder's own bid. The previous higher bidder cannot be restored to his earlier position by another bidder's retraction; and the auctioneer is not bound to accept any bid at all, however high. He may withdraw the lot before the hammer falls, restart the bidding, or reject all bids if a notified reserve price has not been reached.
Section 64(4) — the seller's bidding must be expressly reserved
The fourth sub-clause is anti-puffing. Where a sale by auction is not notified to be subject to a right to bid by or on behalf of the seller, it is not lawful for the seller to bid himself, or for any person to bid on his behalf. Any sale contravening this rule is voidable at the option of the buyer.
The doctrinal target is the practice of puffing — the seller covertly running up the price by his own pretended bids or those of confederates planted in the audience. The buyer is entitled to know whether he is bidding against genuine third-party demand or against the seller himself. Section 64(4) creates a clear statutory rule: if the seller wishes to retain a right of bidding, he must announce it in advance. If he does not announce, he may not bid; and if he bids without announcement, the buyer can avoid the sale.
The principle was at the heart of Warlow v. Harrison (1859) 1 E&E 309, decided before the modern statute. There the auctioneer was sued by the highest genuine bidder in a sale advertised "without reserve", after the seller's agent intervened with a fictitious bid. The court accepted that the auctioneer's announcement of "without reserve" was a collateral undertaking that the sale would not be affected by the seller's own bidding, and that the auctioneer could be sued on that undertaking. Section 64(4), read with the case, gives the buyer two layers of protection: the contract may be avoided, and an auctioneer who participates in concealed seller-bidding may face an action on his collateral promise.
Section 64(5) — reserve or upset price
The fifth sub-clause permits the auctioneer to conduct the sale subject to a reserve or upset price. A reserve price is a minimum at which the seller will accept a bid; bids below the reserve are not, by the contract, capable of being accepted. The reserve may be public — announced to the audience — or private, kept by the auctioneer as a confidential figure beyond which he must not go.
A sale advertised "without reserve" is the opposite case. The seller has bound himself to sell to the highest bidder, however low the bid. The auctioneer's announcement is a collateral undertaking. If, in such an auction, the seller withdraws the goods after a genuine bid is made, the highest bidder may have a remedy against the auctioneer for breach of the collateral promise — again the Warlow v. Harrison reasoning.
A widely cited Indian application of the reserve-price doctrine concerns a mercantile-agent disposition. In a celebrated decision noted in the books, an agent entrusted with a car subject to a reserve price sold the car below the reserve to a bona fide purchaser and misappropriated the proceeds. The court held that, since the buyer had purchased from a mercantile agent in good faith, he had a clean title under the mercantile-agent exception. Reserve prices, in other words, bind the principal-agent relationship internally, but do not always defeat the protection given to a good-faith buyer by the nemo dat exceptions.
Section 64(6) — pretended bidding
The final sub-clause — Section 64(6) — closes the loop. If the seller makes use of pretended bidding to raise the price, the sale is voidable at the option of the buyer. Pretended bidding is a fraud on the auction process: bids placed without intention to buy, by the seller or his confederates, designed to push the genuine bidder higher.
This is conceptually distinct from Section 64(4). Section 64(4) is about the identity of the bidder — the seller cannot bid himself unless he has reserved the right. Section 64(6) is about the character of the bidding — even a bid by a third party becomes vitiated if it is a pretended bid not made in good faith. The two rules together make any covert manipulation of the bidding process — whether by direct seller bidding, by puffing, or by confederate fake bids — voidable at the buyer's option.

Take the SoGA mock →Auctioneer's authority and liability
An auctioneer is, in technical terms, a mercantile agent. He is in possession of the goods with the seller's consent for the purpose of sale; he has authority, in the customary course of his business, to sell. The buyer is therefore entitled to assume that the auctioneer has authority to pass title under Section 27, and a sale by an auctioneer in the ordinary course of his business will pass a clean title to a buyer in good faith and without notice of any defect in authority.
The position changes if the auctioneer steps outside the customary course — for example, sells the goods privately rather than at auction, sells at an unusual time or place, or sells at a manifestly low price designed to arouse suspicion. Such a sale is not within the mercantile-agent exception, and the buyer takes subject to the original owner's rights.
The auctioneer also owes duties to both sides. To the seller, he owes the ordinary duties of an agent — to obtain the best reasonably available price, to follow the seller's instructions on reserve, to account for the proceeds. To the buyer, he owes the duties stated above and may be liable on the collateral promises he announces ("without reserve", "highest bid takes"). An auctioneer who, knowing of a concealed defect in the seller's title, conceals it from the buyer is liable in deceit irrespective of statute.
Distinction from ordinary sale of goods
An auction sale shares the bones of an ordinary sale of goods — there must be a buyer and a seller, goods, a price, mutual assent — but the procedure is materially different. Three points of contrast:
- Formation. An ordinary sale is concluded by an offer and a matching acceptance between two parties. An auction is concluded by a chain of competing offers (bids) and a single, final acceptance signified by the fall of the hammer.
- Identity of seller. An ordinary seller may haggle with each buyer separately. An auction seller commits, by the fact of holding an auction, to deal with the highest bidder; if the auction is "without reserve", he is doubly bound.
- Statutory overlay. Section 64 imposes special rules — separate-lot presumption, fall-of-the-hammer rule, retraction of bid, anti-puffing, reserve price, pretended-bidding fraud — that have no exact analogue outside the auction context.
Conceptually, an auction is a structured exception to the general scheme of contract of sale; it imports a public-bidding mechanism into the ordinary offer-and-acceptance frame.
Knock-out agreements and bidding rings
The auction context produces two related practices that have their own jurisprudence: knock-out agreements among bidders, and mock auctions designed to gull innocent buyers.
A knock-out agreement is an arrangement among prospective bidders that only one of them will bid at the public auction; the others will hold off; the goods are bought cheaply at a single bidder's price; and the gain is shared in a private settlement among the conspirators. The English position is that a knock-out is not, without more, a fraud on the seller — it is merely an aggregation of buyers' interests — and is unlawful only when it falls foul of competition law or works as part of a wider deception. Indian courts have followed the same line, treating knock-outs as enforceable inter se unless they involve some additional element of fraud, coercion or breach of fiduciary duty.
A mock auction, by contrast, is a fraud against the buyers. The conduct typically involves a seller or auctioneer who pretends to conduct an auction but actually orchestrates the bidding to extract more from real bidders by mixing in fictitious bids, free "gifts", or refunds to chosen confederates. Mock auctions of consumer goods are now widely regulated by special legislation in jurisdictions that have a Mock Auctions Act, and even where there is no such legislation Section 64(6) gives the duped bidder a remedy by treating the sale as voidable at his option.
Practical and exam-angle observations
For the judiciary aspirant, a few patterns recur in Section 64 fact-patterns. First, examiners love the fall of the hammer question — be ready to identify the precise moment of acceptance and to apply Payne v. Cave. Second, the without-reserve hypothetical, in which the seller withdraws the goods after a genuine bid, is a classic trap; the answer turns on the auctioneer's collateral promise rather than on the contract of sale itself. Third, the seller-bidding scenario is best worked through the dichotomy between Section 64(4) (identity) and Section 64(6) (character), as set out above. Fourth, the passing-of-property analysis under Dennant v. Skinner (1948) — property passes at the hammer, irrespective of post-hammer conditions — is the most-tested example of the interaction between Section 64 and the rules in Sections 18 to 25. Fifth, bear in mind the wider linkage between auctions and the unpaid seller's right of resale under Section 54: a seller's resale by public auction following the buyer's default is a common practical arrangement, and the procedure of Section 64 governs that resale just as it governs the original sale.
Auctions as a remedial procedure under Section 54
The interaction with the unpaid seller's right of resale deserves a separate paragraph. Where the unpaid seller resells after notice under Section 54(2), public auction is by far the most defensible mode of resale. It demonstrates that the resale was made in good faith, in a transparent forum, at a market-tested price. A seller who chooses a private resale exposes himself to the buyer's challenge that the price obtained was not the best reasonably available, and that the damages claim under Section 54(2) is therefore inflated. By contrast, a properly advertised auction, conducted with the formalities of Section 64, is hard to attack on those grounds. For this reason, in commercial practice, unpaid-seller resales of standard goods almost always proceed by auction.
Quick recap — checklist for any auction problem
- Are the goods being sold in lots? — Section 64(1) presumption applies.
- Has the auctioneer announced completion of the sale? If not, no contract has formed (Section 64(2)).
- Has any bidder retracted his bid before completion? — Section 64(3) makes the retraction effective.
- Has the seller bid himself or used a person to bid on his behalf? Was the right reserved? — Section 64(4).
- Was a reserve or upset price announced? — Section 64(5). If "without reserve", what are the auctioneer's collateral promises?
- Are any of the bids pretended bids by the seller's confederates? — Section 64(6) makes the sale voidable.
- Did property in the lot pass at the fall of the hammer under Section 20? Apply Dennant v. Skinner.
- Is the auctioneer acting within the mercantile-agent exception under Section 27 in passing title?
Worked through this checklist, Section 64 yields predictable answers. The architecture is tight: a public-auction analogue of offer-acceptance-revocation built on top of the ordinary sale-of-goods machinery, with two anti-fraud rules in sub-clauses (4) and (6) that catch the classic puffing and pretended-bidding schemes. For deeper context on the case-law backbone, the chapter on landmark cases on the Sale of Goods Act tracks the line of decisions from Payne v. Cave through Warlow v. Harrison to Dennant v. Skinner.
Frequently asked questions
When exactly is an auction sale complete under Section 64(2)?
Under Section 64(2), the sale is complete only when the auctioneer announces its completion — typically by the fall of the hammer, but any other customary manner (a cry of "sold", a wave of the hand) will do where the trade so accepts. Until that moment the highest bid is merely an offer that may be retracted under Section 64(3). Payne v. Cave (1789) is the leading authority. The point matters for the passing-of-property analysis under Sections 18 to 25: in Dennant v. Skinner (1948) property in a car was held to have passed at the hammer, irrespective of a post-hammer document purporting to keep title in the seller.
Can the seller bid at his own auction?
Only if the right has been expressly reserved before the auction begins. Section 64(4) declares it unlawful for the seller to bid himself, or to employ another person to bid on his behalf, in an auction not notified to be subject to such a right of bidding. Any sale that contravenes the rule is voidable at the option of the buyer. The doctrinal target is the practice of puffing — covertly running up the price by the seller's own bids — and the rule is reinforced by Section 64(6), which makes the sale voidable where the seller has used pretended bidding to raise the price.
What is the difference between a "reserve price" and a "without reserve" auction?
Section 64(5) permits an auction to be conducted subject to a reserve or upset price — a minimum below which the auctioneer is not authorised to sell. The reserve may be public or kept confidentially by the auctioneer. A "without reserve" auction is the opposite: the seller has committed to sell to the highest bidder, however low. The auctioneer's announcement of "without reserve" is itself a collateral undertaking, on which the highest genuine bidder may sue if the seller withdraws the goods after the bid — Warlow v. Harrison (1859) is the leading authority on that collateral promise.
Does each lot in an auction give rise to a separate contract?
Yes, prima facie. Section 64(1) creates a rebuttable presumption that where goods are put up for sale in lots, each lot is the subject of a separate contract of sale. The consequences are practical: a defect in one lot does not infect the others; a bid for one lot does not bind the bidder to bid for any other; and passing of property, risk and remedies attach lot by lot. The presumption may be displaced by a clear announcement before the auction begins that the lots are to be taken as a single contract — for example, where a complete library is being sold.
Are knock-out agreements among bidders unlawful?
Not by themselves. A knock-out agreement is an arrangement among prospective bidders that only one of them will bid at the auction and the gains will be shared privately. The English and Indian courts have generally treated such arrangements as enforceable between the participants and not, without more, as a fraud on the seller — they are merely an aggregation of buyers' interests. They become unlawful when they involve an additional element of fraud, breach of fiduciary duty or contravention of competition law. A "mock auction", by contrast, is a fraud on the buyers and is voidable at the buyer's option under Section 64(6).
