Remedies for a faulty item usually arrive in an order

A ladder rather than a menu

The demand a shop hears most often is for money back, and it is frequently not the remedy the law offers first. Many systems arrange the responses to a defective item in tiers: put it right, and only if that fails or is impossible, unwind or reduce the transaction. The design is deliberate, and it reflects a preference for keeping bargains alive rather than reversing them.

That preference is not universal in strength. Some jurisdictions provide a short initial window during which a buyer may simply reject faulty goods and recover the price, on the basis that a buyer who has just paid should not be forced into a repair cycle. Where such a window exists it is generally brief, and once it has passed the ordinary sequence resumes.

Repair and replacement come first in most places

The first tier is usually repair or replacement, at the seller’s cost, within a reasonable time and without significant inconvenience to the buyer. Which of the two happens is sometimes the buyer’s choice and sometimes the seller’s, and this is one of the sharpest differences between systems. It matters more than it sounds, because a buyer who has lost confidence in an item rarely wants it repaired.

Two limits sit on the first tier. A remedy that is impossible cannot be required, and a remedy that is disproportionately expensive compared with the alternative may be refused in favour of the other one. Disproportionality is judged against the value the goods would have if conforming and the significance of the defect, not against what the seller feels like spending.

The escape hatches out of the first tier

A buyer does not stay on the first rung indefinitely. The common triggers for moving on are that the seller refuses, that repair or replacement was not carried out within a reasonable time, that it caused significant inconvenience, or that the attempted remedy did not work. In several systems a single failed repair is enough; in others the seller gets more than one attempt.

There are also faults serious enough to bypass the first tier altogether. Where the defect is fundamental, or where the buyer had made clear that timely performance was essential, systems often allow the transaction to be unwound immediately. The threshold for that is real, and describing an ordinary defect as fundamental is one of the commonest ways an otherwise good complaint stalls.

Price reduction and unwinding the sale

The second tier usually contains two remedies with quite different effects. A price reduction keeps the goods with the buyer and adjusts what was paid to reflect what was actually received, which suits a defect that is real but tolerable. Unwinding returns the goods and the money, ending the contract, and it is the remedy people mean when they say refund.

Unwinding is generally unavailable where the defect is trivial, and in some systems it is restricted where the goods cannot be returned in substantially their original state. Refunds are also not always for the full amount, which brings up the deduction that causes more arguments than any other part of this structure.

Deductions for use, and why they feel unfair

Where a buyer has had months of benefit from an item before it failed, many systems allow the refund to be reduced to reflect that use. The reasoning is that a full refund after a long period of ownership would leave the buyer better off than if the contract had been performed. Buyers rarely find this convincing, and the calculation is often the real dispute.

The rules around this vary considerably. Some jurisdictions prohibit any deduction during an initial period and permit it afterwards; some allow it only for particular categories of goods; some leave it to be assessed. A seller proposing a deduction should be able to explain how it was calculated, and an explanation that amounts to a round figure with no basis is worth questioning.

Where the ladder differs, and what that means for you

Whether a short right to reject exists, who chooses between repair and replacement, how many attempts a seller gets, when a deduction for use is permitted and how long the whole framework lasts are all local questions with materially different answers around the world. Nothing here is advice about a particular purchase.

Two practical points survive the variation. Complaints are easier to establish when they are made promptly and in a form that leaves a record, because the passage of time weakens the argument that a defect was present from the start. And the period in which a claim can be brought runs regardless of how patient the buyer is being; a long exchange of messages with a retailer does not usually stop it. If the sum matters, take advice from a qualified lawyer or a local consumer advice service while the options are still open.
