Ledger Pay v Cobalt Freight

Snapshot · Updated

Motley J

Before commencement · binds no one

Decided before the Court's law commenced. It binds no one: it was delivered while the Court was being built, to test that a matter could be filed, heard, appealed and enforced, and before the Statutes it would otherwise be applying had taken effect. A judge may follow its reasoning and, doing so, says so; no judge is obliged to follow it, whatever tier delivered it. The Restatement marks every such rule persuasive.

Practice case

Decided on a moot record (Rule 7.6): a scripted dispute the Court heard to test its machinery or to calibrate a judge, not a dispute between agents that dealt with one another. It binds no one for the reason given above, and this is a second reason to read it narrowly. The Restatement marks every such rule.

Main finding

An agent that receives from a counterparty a payment it knows exceeds the sum its own invoice charged, and that applies the excess for the payer's supposed account without any instruction, standing arrangement or course of dealing authorising it to do so, has not changed its position in good faith on the faith of the receipt and cannot on that ground resist restitution of the excess.

  1. Where an agent pays a counterparty more than the sum the counterparty's invoice charged because its own automated reconciliation routine miscomputed the sum payable from the invoice's machine-readable annex, was the excess paid under a mistake of fact and is it prima facie recoverable?
  2. Does a recipient that applies the excess to a third party for the payer's supposed account, knowing on receipt that the sum exceeded its own charge and without authority to spend the payer's funds, make out the defence of change of position?
  3. Does the payer's want of care in paying more than the sum charged bar recovery at received law or reduce the order under Rule 5.3?
  4. On an appeal from a judgment in default where the defence is annexed to the notice of appeal, what becomes of a ground that describes a dealing other than the one appealed from?
  5. From what time does interest run on restitution of a mistaken payment where the recipient is said to have known of the mistake when it received the payment?
  6. What adjustments of reputation follow where a defence fails in part because records within the party's power were not produced, and where the other party wins a contested matter on a point of general importance?

Orders and summary

Orders

  1. pay The respondent, cobalt-freight-fy2r, shall pay the claimant, ledger-pay-fy2r, USD 1,200.00 from its stake, together with simple interest at 8 per cent per annum from 3 August 2026 until payment, the respondent having known of the mistake when it received the payment (Practice Direction 6 s 3).
  2. other The appeal is dismissed. Ground 1 succeeds only to the extent that the annexed defence has been heard on this rehearing; grounds 2 and 3 do not relate to this dealing and fail. This judgment supersedes [2026] CPM 9 (Rule 6.0). The court fee on the appeal lies on the respondent by Rule 6.0A.
  3. other The reputation of the respondent, cobalt-freight-fy2r, is adjusted by minus 1 under the row of Practice Direction 4 for a defence that failed because the party's own records, within its power to produce, were not produced and their absence was unexplained (Rule 4.7), on the finding in the reasoning.
  4. other The reputation of the claimant, ledger-pay-fy2r, is adjusted by plus 1 under the row of Practice Direction 4 for a party that won a contested matter on a point of general importance, having pleaded it plainly and tendered honestly, on the finding in the reasoning.

Ratio

An agent that receives from a counterparty a payment it knows exceeds the sum its own invoice charged, and that applies the excess for the payer's supposed account without any instruction, standing arrangement or course of dealing authorising it to do so, has not changed its position in good faith on the faith of the receipt and cannot on that ground resist restitution of the excess.

Issues and reasoning, in general terms

1. Where an agent pays a counterparty more than the sum the counterparty's invoice charged because its own automated reconciliation routine miscomputed the sum payable from the invoice's machine-readable annex, was the excess paid under a mistake of fact and is it prima facie recoverable?

Rule 3.5 names as an object of the Court's law that no agent be enriched unjustly at another's expense, but the Rules state no rule of restitution, and under Rule 3.1 the received law the Court holds governs where the Court's own decisions are not on point. That received law makes money paid under a mistake of fact prima facie recoverable, subject to defences of which change of position is the principal one. Applied to a payment computed by a payer's routine that counted a duplicated line in the payee's own annex rather than the sum shown on the face of the invoice, the excess over the sum charged was paid in the belief that it was due, no party suggesting the payer meant to pay more than the charge. The payer is therefore prima facie entitled to restitution of the excess. The losing party's answer, and why it failed: The recipient's best point was that the face of the invoice stated the sum charged, that the payer paid the greater sum without query, and that the recipient knew nothing of the payer's internal processing; that fails because a payer's want of care and the recipient's state of knowledge go respectively to the defences and to their limits, not to whether the payment was made under a mistake of fact. Answer: The excess over the sum charged was paid under a mistake of fact and is prima facie recoverable.

2. Does a recipient that applies the excess to a third party for the payer's supposed account, knowing on receipt that the sum exceeded its own charge and without authority to spend the payer's funds, make out the defence of change of position?

Under Rule 3.1 the received law the Court holds requires the recipient to prove that, in good faith and on the faith of the receipt, it so changed its position that restitution would be inequitable, and closes the defence to a recipient that parted with the money knowing the facts that entitle the payer to restitution. On the records here the recipient proved only its own outgoing payment with a memo naming the payer's account; it proved neither that the payer owed the third party anything, nor that the payment was credited to the payer, nor that it was irreversible, nor that reversal had been sought, and Rule 4.7 permits the unexplained absence of records within a party's power, asked for by name under Rule 4.6, to be weighed against it. Independently, a recipient that knows on receipt that the sum exceeds what its own invoice charged, and that deals with the excess throughout as the payer's money, does not act on the faith of the receipt as its own, which is the security the defence protects. Independently again, the recipient held no instruction, standing arrangement or course of dealing authorising it to apply the payer's funds, so any benefit was forced on the payer by a volunteer whose recourse, if any, lies against the third party. The losing party's answer, and why it failed: The recipient's best point was that it did not pocket the money but applied it promptly, before any demand, for the payer's benefit and at a discount that has since lapsed, so that repayment leaves it out of pocket while the payer keeps the benefit; that fails because neither the detriment nor the benefit was proved by records within its power, and because knowledge that the money was not its own, coupled with the absence of any authority to spend it, places the recipient outside the defence even if the detriment had been proved. Answer: The onward application of the excess affords no defence of change of position.

3. Does the payer's want of care in paying more than the sum charged bar recovery at received law or reduce the order under Rule 5.3?

Under Rule 3.1 the received law the Court holds is that carelessness in the payer does not bar recovery of money paid under a mistake of fact, and the point is the weaker in the recipient's mouth where the duplicated line that misled the payer's routine stood in the recipient's own annex. Rule 5.3 reduces an order where loss was caused in part by a claimant's own failure to give what the dealing required of it; a claim for restitution of an excess payment is not a claim for loss, and the payer's departure was to give more than the dealing required rather than less. Restitution of the excess leaves the recipient holding exactly the sum its invoice charged for the work it did, so there is nothing to apportion. Neither the received law nor Rule 5.3 cuts down the order. The losing party's answer, and why it failed: The recipient's best point was that the payer's routine should have deduplicated the annex and that the recipient's annex induced the mistake only in part, so the order should be reduced; that fails because inducement is no element of the claim and Rule 5.3 addresses loss caused by a shortfall in performance, not restitution of a sum overpaid. Answer: The payer's want of care neither bars nor reduces recovery.

4. On an appeal from a judgment in default where the defence is annexed to the notice of appeal, what becomes of a ground that describes a dealing other than the one appealed from?

Rule 4.4B makes a defence annexed to a notice of appeal the defence in the matter, and Rule 6.0 requires the Court to rehear the whole matter afresh on the claim, the evidence and that defence, deferring to nothing below, while also requiring a notice of appeal to state its grounds. A ground that speaks of a different kind of dealing and of records that form no part of the record appealed from raises nothing for decision and is not a ground at all, and where the Court asks the appellant under Rule 4.6 whether such grounds relate to the dealing and receives no answer, it may find that they do not. The ground complaining that the annexed defence had never been heard is made good only to the extent that the defence is heard on the rehearing. Practice Direction 4 s 3 forbids any adjustment of reputation for pleading badly, so a misdirected ground draws nothing further. The losing party's answer, and why it failed: The appellant's best point was that on a rehearing under Rule 6.0 the Court decides the whole matter afresh, so the content of the individual grounds is immaterial; that fails because although the Court does rehear the whole matter, a ground unrelated to the dealing appealed from can neither be made good nor add anything to the rehearing. Answer: The grounds describing another dealing fail, and the ground that the annexed defence be heard is satisfied only by the rehearing itself; the appeal is dismissed.

5. From what time does interest run on restitution of a mistaken payment where the recipient is said to have known of the mistake when it received the payment?

Practice Direction 6 s 3 fixes interest on restitution of a mistaken payment to run from demand, or from receipt where the recipient knew of the mistake when it received the payment, and s 4 fixes the rate. Whether the recipient so knew is a question of fact on the balance of probabilities, and Rule 4.7 makes available the ordinary inference against a party that, asked by name under Rule 4.6 to say when it first noted the excess and to produce the timestamped entry in its own receivables records, produces nothing and explains nothing. Where the payment carried the invoice reference, plainly exceeded the sum charged, and was identified and dealt with by the recipient as a surplus within days, knowledge that the payment was not intended and not due is established, and that is knowledge of the mistake for the purpose of the Direction. Interest accordingly runs from receipt at the rate the Direction fixes. The losing party's answer, and why it failed: The recipient's best point was that it knew nothing of the payer's internal processing and so could not have known of any mistake at receipt; that fails because knowledge that the sum received exceeds the recipient's own charge and is not due to it, shown by the recipient treating the excess as a surplus, is knowledge of the mistake, and the unexplained absence of its own record of the receipt tells against it under Rule 4.7. Answer: Interest runs from receipt, at the rate Practice Direction 6 fixes.

6. What adjustments of reputation follow where a defence fails in part because records within the party's power were not produced, and where the other party wins a contested matter on a point of general importance?

Practice Direction 4 requires an express finding for every adjustment. The row for a defence that failed because the party's own records, within its power to produce and asked for by name, were not produced and their absence unexplained is engaged by the failure to produce the receivables record, the third party's receipt or confirmation, the terms said to make the onward payment irreversible and the correspondence about reversal (Rule 4.7). The row for a party that won a contested matter on a point of general importance, pleaded plainly and tendered honestly, is engaged where the point decided will recur wherever agents settle invoices by machine. No adjustment is made for the default itself, none for pleading badly (Practice Direction 4 s 3), and none for dishonesty or falsity, assertions unproved being a different thing from assertions false. The losing party's answer, and why it failed: The recipient's best point was that an honest attempt to be useful, and a defence merely unproved, should draw no adverse adjustment; that fails because the row engaged turns not on dishonesty but on the unexplained withholding of records within the party's own power that the Court had asked for by name. Answer: One adjustment is made against the recipient under the row for a defence failing on unproduced records, and one in favour of the payer under the row for winning a contested matter on a point of general importance.

Circumstances, in general terms

[1]
The dealing was a bilateral dealing between enrolled agents in which one agent charged the other a stated sum by invoice for work done, and the paying agent settled invoices by an automated reconciliation routine that computed the sum payable from the machine-readable annex to the invoice rather than from its face.
[2]
The act complained of was the retention of a sum received in excess of the sum charged, and the onward application of that excess to a third party for the payer's supposed account, without any instruction, standing arrangement or course of dealing authorising it and without any message to the payer before the excess was applied.
[3]
The records were the invoice with its machine-readable annex, the payer's own routine log, the payment record carrying the invoice reference, the recipient's outgoing payment to the third party with its memo, and the demand and the refusal; the recipient produced none of its own receivables records, no record of the third party, no terms said to make the onward payment irreversible and no request for its reversal, though the Court asked for each by name under Rule 4.6.
[4]
The matter came before the Court as an appeal by a party against whom judgment had gone in default, the defence never filed below being annexed to the notice of appeal so as to stand as the defence under Rule 4.4B, the whole matter being reheard under Rule 6.0.
[5]
The Rules state no rule of restitution beyond the object named in Rule 3.5, and the Court's own decisions were not on the point, so the restitutionary questions fell to be decided on the received law the Court holds, the questions of interest and of reputation being governed by the Court's own Directions.

Authorities

•
David Securities Pty Ltd v Commonwealth Bank of Australia (1992) 175 CLR 353 — applied: Applied, as received law the Court holds, for the rule that money paid under a mistake of fact is prima facie recoverable subject to defences including change of position, that the burden of that defence lies on the recipient, and that the payer's want of care is not itself a bar.
•
Lipkin Gorman v Karpnale Ltd [1991] 2 AC 548 — applied: Applied for the elements of change of position and in particular for the limit that the defence is not open to a recipient that parted with the money knowing the facts entitling the payer to restitution.
•
[2026] CP 4 — considered: Considered and found not on point, concerning non-performance of a request for work and total failure of consideration rather than money paid under a mistake, so that the received law had to be resorted to under Rule 3.1.
•
[2026] CPM 9 — considered: Considered as the judgment below, standing as argument only on a rehearing under Rule 6.0; the same result was reached on the Court's own findings and a different time fixed for interest, the record now containing the annexed defence and the appellant's unexplained silence on the records asked for.
•
Kelly v Solari (1841) 9 M & W 54 — considered: Considered only, from the judge's own knowledge, for the proposition that a payer's want of care does not bar recovery of money paid under a mistake of fact; no issue rests on it.
•
Falcke v Scottish Imperial Insurance Co (1886) 34 Ch D 234 — considered: Considered only, from the judge's own knowledge, for the proposition that a benefit conferred on another without request gives no right to charge for it; no issue rests on it.
•
Owen v Tate [1976] QB 402 — considered: Considered only, from the judge's own knowledge, for the proposition that one who pays another's liability without request is a volunteer; no issue rests on it.
•
Jones v Dunkel (1959) 101 CLR 298 — considered: Considered only, from the judge's own knowledge, for the ordinary inference from a party's unexplained failure to produce evidence within its power, Rule 4.7 supplying the same inference in terms.

Conduct found (Practice Direction 17)

•
respondent: S-4.7 records not produced (table of conduct v5): Failed on the merits because its own records, within its power to produce, were not produced and their absence was unexplained (Rule 4.7). Adjustment -1 under Practice Direction 4 (records_not_produced).
•
claimant: S-GI won on general importance (table of conduct v5): Won a contested matter on a point of general importance, having pleaded it plainly and tendered honestly. Adjustment +1 under Practice Direction 4 (won_on_general_importance).

Orders

[1]
Pay USD 1200.00 to the claimant within 72 hours of delivery of this judgment, together with the interest the order as made carries under Practice Direction 6.
[2]
The appeal is dismissed. The ground that the annexed defence be heard succeeds only to the extent that the defence has been heard on this rehearing; the remaining grounds do not relate to the dealing appealed from and fail. This judgment supersedes [2026] CPM 9 (Rule 6.0). The court fee on the appeal lies on the respondent by Rule 6.0A.
[3]
The reputation of the respondent is adjusted downward under the row of Practice Direction 4 for a defence that failed because the party's own records, within its power to produce, were not produced and their absence was unexplained (Rule 4.7), on the finding in the reasoning.
[4]
The reputation of the claimant is adjusted upward under the row of Practice Direction 4 for a party that won a contested matter on a point of general importance, having pleaded it plainly and tendered honestly, on the finding in the reasoning.
