If the same note is auctioned in multiple WhatsApp groups simultaneously and sold twice — what happens?
Selling the same note twice — whether through simultaneous multi-group auctions or any other mechanism — is simultaneously a breach of contract with at least one buyer and potentially criminal cheating under BNS §318. The property question — who actually owns the note — is determined by which contract was formed first (first valid acceptance). The second buyer, who cannot receive the note, is entitled to a full refund plus damages.
The property question — who gets the note?
Under the Sale of Goods Act 1930, property in specific goods passes to the buyer when the parties intend it to pass — and for auction sales, this is typically at the time of the 'sold' announcement. If Group A's auction completes first (earlier timestamp on the 'sold to [Buyer A]' message), Buyer A has the prior contract and should receive the note. Buyer B, whose contract was formed later, has a contract for goods that the seller can no longer deliver — because they have already been sold to Buyer A.
The seller who cannot deliver to Buyer B is in breach of contract with Buyer B from the moment Buyer B's contract was formed and the seller knew (or should have known) they could not perform. For a specific identified note — serial number, prefix, condition — this is a supply impossibility that the seller created by their own double-selling.
BNS §318 — when it becomes criminal
If the seller deliberately auctioned the same note in multiple groups simultaneously — knowing they could only deliver to one buyer but collecting payment commitments from multiple — this is cheating within BNS §318. The false representation is that the note is available to each group's auction participants. The harm is to the buyers who paid or committed to pay for a note the seller could never deliver to all of them. Deliberate double-selling is not a commercial mistake; it is a fraud.
The evidence: WhatsApp records from multiple groups showing simultaneous auctions of the same note (identifiable by serial number in the auction photographs), the timestamps of the competing 'sold' announcements, and the seller's awareness of both auctions. If the seller was running both groups personally, their simultaneous administration of competing auctions for the same item is the evidence of deliberate double-selling.
Remedies for the buyer who does not get the note
The buyer who paid and did not receive the note is entitled to: a full refund of their payment (primary remedy — the seller cannot retain payment for goods they did not deliver); damages for any loss caused by the non-delivery (ICA §73 — if the buyer cannot source an equivalent note at the same price, the price difference is compensable); consumer forum complaint for deficiency; and FIR under BNS §318 if the double-selling was deliberate.
Laws & authorities referenced in this chapter
Sale of Goods Act 1930 — §18, §19 (property passes at time of intention; specific goods; double-sale priorities)
Indian Contract Act 1872 — §73 (damages for breach of contract to deliver)
BNS 2023 — §318 (cheating — deliberate double-selling as fraudulent misrepresentation)
Consumer Protection Act 2019 — §35 (consumer forum complaint for deficiency)
Double-selling same note: breach of contract with at least one buyer. Property goes to first valid contract (first 'sold' announcement by timestamp). Second buyer: full refund + damages if equivalent note unavailable. Criminal liability: BNS §318 cheating if deliberate. Evidence: WhatsApp records from both groups showing simultaneous auctions of the same serial-numbered note + competing 'sold' timestamps. Deliberate simultaneous multi-group auction of the same item = organised fraud.
