Someone knowingly accepted a payment they had no right to receive — apart from returning it, what else are they liable for?

Interest or fruits, depending on what was received

Article 2159 attaches real financial consequences to bad faith: whoever in bad faith accepts an undue payment, shall pay legal interest if a sum of money is involved, or shall be liable for fruits received or which should have been received if the thing produces fruits. If what was wrongly accepted was money, the bad-faith payee owes legal interest on it, on top of returning the principal. If instead a fruit-bearing thing was wrongly received, the payee owes not just the thing itself but the fruits it actually generated, and even fruits it should have generated had it been properly managed.

Liability for loss or damage to the thing itself

The article goes further than interest and fruits: he shall furthermore be answerable for any loss or impairment of the thing from any cause. This is a notably strict standard. A person who received something in good faith is typically judged more leniently if the thing is later lost or damaged, but a bad-faith payee bears the risk of loss or impairment regardless of cause, meaning even circumstances beyond his control do not excuse him, precisely because he should never have accepted the payment in the first place.

Damages until actual recovery

The bad-faith payee's exposure does not end once the wrongful acceptance is discovered; Article 2159 makes him answerable for damages to the person who delivered the thing, until it is recovered. This ties his liability to the entire period the wrongly delivered payment or property remains unreturned, not merely to the moment of receipt. The longer the bad-faith payee holds onto what was never his to keep, the longer this exposure to interest, fruits, loss, and damages continues to run against him.

Why the standard is harsher than for a good-faith recipient

The law treats bad faith as the decisive factor because someone who knowingly accepts a payment or property they have no right to is not an innocent party caught by an honest mistake; they are consciously keeping something belonging to another. Article 2159 responds to that by making the consequences of holding onto the wrongful payment considerably heavier than they would be for someone who received it honestly believing they were entitled to it, reflecting the greater culpability involved in accepting what was known to be undue.
