Is artificially inflating an auction through self-bids from family members the same as shill bidding?
Yes — bidding by a family member on the seller's instruction, to inflate prices artificially, is shill bidding under the Sale of Goods Act Section 64(d) and Section 64(f), and potentially cheating under BNS Section 318. The relationship between the seller and the bidder is legally irrelevant. What determines whether a bid is a shill bid is the intent: is the bidder genuinely willing to buy the lot if they win, or are they bidding to run up prices for other bidders? The first is legal. The second is a fraud regardless of whether the bidder is a stranger, a friend, or a family member.
The intent test — not the relationship test
The Sale of Goods Act's shill bidding provisions at Section 64(d) and 64(f) do not mention the relationship between the seller and the bidder. Section 64(d) prohibits the seller from employing 'any person' to bid without disclosure — any person, without qualification. Section 64(f) prohibits 'pretended bidding' to raise the price. A family member who bids on the seller's behalf, under the seller's instruction, knowing they will not actually pay if they win — is a pretended bidder within Section 64(f) regardless of their family connection to the seller.
The intent test works in two directions. A family member who genuinely wants the lot for their own collection, bids independently, and would actually pay and keep the note if they won — is a legitimate bidder. Their family relationship to the seller is irrelevant. They are a separate person with a separate collection interest making a genuine bid. This is not shill bidding.
The disclosure rule — vendor bidding by family member
Section 64(c) of the Sale of Goods Act provides that a right to bid may be reserved expressly by or on behalf of the seller, and where such right is reserved, one person on the seller's behalf may bid. This is the vendor bid mechanism — and it is legal provided it is disclosed before the auction. A seller who wishes to have a family member bid on their behalf to protect against undervaluation must: (a) disclose before the auction that the seller has reserved the right to bid; (b) limit this to one person bidding on the seller's behalf.
Without this disclosure: any bidding by a family member on the seller's behalf — however subtly arranged — falls within Section 64(d)'s prohibition. The sale may be treated as fraudulent by the buyer. If the family member's bids successfully inflated the price paid by the genuine winning bidder, the winning bidder can void the transaction and recover their payment.
Online auctions — the multiple account problem
In online numismatic auctions — Facebook Live, WhatsApp groups, Instagram posts — the shill bidding risk is amplified by the ease of creating additional accounts. A seller who uses a family member's Facebook account, or creates a new account for a family member, to place bids on their own lots is: (a) shill bidding under SGA §64(d)/(f); (b) potentially cheating under BNS §318; and (c) personation using computer resources under IT Act §66D if a separate account is used to impersonate a different person. The family relationship is not a shield — it is an aggravating factor that shows the arrangement was deliberate and coordinated.
Family member bidding — the legal spectrum LEGAL: Family member bids independently for their own genuine collection interest; would pay and keep if they won; no coordination with seller LEGAL with disclosure: Family member bids on seller's behalf as declared vendor bid (SGA §64(c)); existence of vendor bidding right disclosed before auction ILLEGAL: Family member bids on seller's instruction to run up prices; does not intend to pay if they win — shill bidding (SGA §64(d)/(f)) ILLEGAL + CRIMINAL: Seller creates separate account for family member specifically to shill bid — BNS §318 cheating + IT Act §66D personation Test: would the family member pay and keep the lot if they won? YES = potentially legal. NO = shill bidding. |

Sale of Goods Act 1930 — §64(c) (disclosed vendor bid: legal; one person on seller's behalf)
Sale of Goods Act 1930 — §64(d) (undisclosed bidding by any person on seller's behalf: fraudulent)
Sale of Goods Act 1930 — §64(f) (pretended bidding to raise price: sale voidable)

Family member shill bidding: same as any other shill bidding — illegal under SGA §64(d)/(f) when done without disclosure and without genuine intent to buy. Test: genuine intent to buy if winning = legal bid; inflating prices for others = shill. Vendor bid by family member = legal ONLY with pre-auction disclosure (SGA §64(c)). Online family shill via separate account: BNS §318 + IT Act §66D. The relationship is irrelevant — the intent is everything.
