What are the legal principles which govern sale of goods by auction?

The Governing Provision — Section 64

Section 64 lays down the framework governing all sales conducted by public auction, whether of goods generally or, by extension, of chattels sold through court process. It addresses six matters that repeatedly arise in the conduct of such sales, each dealt with as a separate numbered rule within the section.

Each Lot Is a Separate Contract — Section 64(1)

Where goods are put up for sale in separate lots, each lot is prima facie deemed to be the subject of a separate contract of sale. This means that a bidder who successfully purchases several different lots at the same auction does not thereby merge all his purchases into a single, unified contract — each lot retains its own independent legal character. This was affirmed in McManus v. Fortescue, where the principle of treating each lot as a distinct contract was applied to determine the rights and remedies flowing from separate purchases made at the same auction event.

When the Sale Becomes Complete — Section 64(2)

The sale is complete only when the auctioneer announces its completion, ordinarily by the fall of the hammer, or in some other customary manner recognised at that particular auction. Until such an announcement is actually made, any bidder remains free to retract his bid entirely. This reflects the underlying legal character of a bid as merely an offer or proposal — each successive bid is simply the latest proposal on the table, capable of withdrawal at any point before it is accepted, and it is only the auctioneer's acceptance, typically signalled by the hammer's fall, that converts the last standing bid into a binding contract. Where a court is conducting the auction, this acceptance may additionally remain subject to the court's confirmation before the sale is truly final. The illustration of a buyer bidding for a picture at auction demonstrates this principle vividly — if the picture is damaged by accident before the hammer falls, the loss remains with the seller, since no completed sale has yet occurred, but if the accident happens after the hammer falls, the loss falls upon the buyer, since the sale is by then complete and property has passed.

The Seller's Right to Bid — Section 64(3) and (4)

A right to bid may be reserved expressly by, or on behalf of, the seller, and where such a right has been expressly reserved — but not otherwise — the seller, or one person acting on his behalf, may bid at the auction. This carefully qualified language reveals the underlying policy: ordinarily, a seller bidding at his own auction, whether personally or through an agent, would be fundamentally unfair to genuine bidders, since it allows the seller to artificially drive up the price without any real intention of purchasing the goods himself. Section 64(4) accordingly makes this prohibition explicit — where the sale has not been notified as being subject to a right to bid on the seller's behalf, it is unlawful for the seller to bid himself, or to employ any other person to bid for him, and it is equally unlawful for the auctioneer to knowingly accept any such bid from the seller or his nominee. Any sale that contravenes this rule may be treated by the buyer as fraudulent, giving him the option to avoid the transaction altogether.

Reserved or Upset Price — Section 64(5)

The sale may be notified as being subject to a reserved or upset price — the term "upset price" being simply the Scottish equivalent of what is elsewhere termed a reserve price. Where such a reserve is fixed, every bid received is treated as a proposal conditional upon that reserve price actually having been reached, and correspondingly, even the fall of the hammer itself is treated as conditional on the reserve having been met. If bidding fails to reach the reserve, the auctioneer retains the discretion to cancel or postpone the sale altogether, or alternatively to accept the highest bid received only conditionally or provisionally, subject to the seller's later confirmation. It bears emphasising that reserving a minimum or upset price is an entirely distinct matter from reserving a right for the seller himself to bid — the two rules, though both dealing with protecting the seller's interests, operate independently, and the presence of one does not imply the presence of the other.

The Supreme Court has recognised that an auctioneer is free to fix his own governing terms and conditions for conducting a particular auction, and once fixed, these conditions bind the rights of all participating parties. Where, for example, the Coffee Board's auction rules expressly reserved the Board's right not to be bound to accept the highest bid submitted, this was held to necessarily imply that the Board could freely accept any lower bid instead, without being compelled to prefer the highest offer received.

Pretended Bidding to Inflate the Price — Section 64(6)

Where the seller makes use of pretended bidding as a device to artificially raise the price, the resulting sale is voidable at the option of the buyer. This rule targets a specific form of manipulation distinct from the outright prohibited bidding addressed under Section 64(4) — here, the seller employs fictitious or collusive bids, sometimes called "puffing," to create a false impression of genuine competitive demand, thereby inducing an unsuspecting buyer to pay more than he otherwise would have offered. The remedy the Act provides is not automatic voidness but voidability, leaving the defrauded buyer the choice of either affirming the sale or setting it aside once the pretence is discovered.

Knock-Out Agreements Among Bidders

A related, though converse, situation arises where intending bidders themselves combine to stifle competition among one another by agreeing not to bid against each other — commonly termed a "knock-out" agreement. Such combinations among bidders are not considered unlawful under the general principles governing auction sales, though the seller retains the ability to protect his own interests against this practice by fixing a suitable reserve bid in advance. Where a reserve price has genuinely been fixed, every bid submitted, and even the ultimate fall of the hammer, remains conditional on that reserve actually having been reached.

Passing of Property in Auction Sales

An important consequence flowing from the general scheme of the Act, though not stated within Section 64 itself, concerns exactly when property in the goods passes to the successful bidder. This was clarified by the Supreme Court in Consolidated Coffee Ltd v. Coffee Board, Bangalore, holding that in an auction sale of chattels, property passes to the purchaser upon acceptance of his bid — and this occurs not because of any special rule contained within Section 64 itself, but rather by application of the ordinary rule found in Section 20, governing unconditional contracts for specific goods in a deliverable state. This confirms that auction sales, despite their distinctive procedural features, remain firmly rooted within the Act's general scheme for the passing of property, with Section 64 supplying only the procedural rules peculiar to the auction process itself.
