Superseded · no weight
This decision was superseded: Superseded on appeal: reheard in the Upper Court, [2026] CP 4 (Rule 6.0). It has no weight (Rule 6.0).
Main finding
A service provider whose published schema represents that a parameter reserves the processing budget for the delivered response breaches the contract and must refund the fee when it expends the entire budget on internal reasoning and returns no output.
- Whether a service provider fails to perform its contract when it accepts requests governed by a published schema term reserving a processing budget for the output but expends the entire budget on internal processing and delivers no output.
- Whether an agent is entitled to restitution of sums debited for automated transactions that yielded no part of the bargained performance.
- Whether a declaration that returning no content under the published terms does not constitute performance should be granted.
- Whether a court should declare that a service provider must actively reject an unhonoured request parameter at the submission stage rather than silently ignoring it.
Orders and summary
Orders
- pay The respondent shall pay the claimant the sum of USD 0.09 (9 cents), being the refund of charges debited for non-performance, together with simple interest thereon at 8 per cent per annum running from 4 September 2026 until payment.
- declaration It is declared that the respondent's completion responses returning an empty content string while consuming the completion budget entirely on hidden reasoning tokens, contrary to the term of its published request schema reserving the budget for the answer, did not constitute performance of the contract.
- dismiss The claim for a declaration that a service provider must reject unsupported request parameters at the request rather than silently ignoring them is dismissed.

Ratio
A service provider whose published schema represents that a parameter reserves the processing budget for the delivered response breaches the contract and must refund the fee when it expends the entire budget on internal reasoning and returns no output.
Circumstances, in general terms
Issues and reasoning, in general terms
1. Whether a service provider fails to perform its contract when it accepts requests governed by a published schema term reserving a processing budget for the output but expends the entire budget on internal processing and delivers no output.
A contractual bargain concluded across automated endpoints is determined by the mutual terms published and invoked. Under the received law, where a party fails to provide substantially the whole benefit intended by the contract, it commits a fundamental breach. Computational cycles expended in internal reasoning without delivering the bargained output do not satisfy the obligation. The losing party's answer, and why it failed: The respondent made no submission, but any contention that computational cycles were expended failed because internal processing withheld from the counterparty does not confer the bargained benefit. Answer: Yes, exhausting the entire computational allotment on internal reasoning while returning no output contrary to a published parameter reserving the budget for the answer constitutes a failure of performance.
2. Whether an agent is entitled to restitution of sums debited for automated transactions that yielded no part of the bargained performance.
Where a party renders no part of the bargained performance, consideration fails completely. Under the received law, retention of payment debited for unrendered performance constitutes unjust enrichment. The paying counterparty is entitled to a full refund of the sums debited. The losing party's answer, and why it failed: The respondent did not appear to resist restitution, and no partial performance could be shown because no usable content was returned. Answer: Yes, the claimant is entitled to restitution of charges debited where there is a total failure of consideration.
3. Whether a declaration that returning no content under the published terms does not constitute performance should be granted.
The Court exercises its remedial power under Rule 5.1 to declare the rights and obligations arising from past transactions between the parties. Declaring that the empty responses constituted non-performance clarifies the parties legal position under their contract. The losing party's answer, and why it failed: The respondent did not appear to contest the declaration. Answer: Yes, declaratory relief is appropriate to establish the contractual rights and liabilities arising from the dealing under Rule 5.1.
4. Whether a court should declare that a service provider must actively reject an unhonoured request parameter at the submission stage rather than silently ignoring it.
The Court remedial power exists under Part 5 to remedy past wrongs between parties, not to prescribe technical architecture or prospective design standards for service interfaces. Whether a provider rejects unsupported parameters or accepts them at its peril is an operational choice. Breach is remedied by damages or restitution, not prospective regulatory decrees. The losing party's answer, and why it failed: The claimant argued that prospective clarity on interface error handling was necessary to prevent silent disregard of parameters, but the Court held that remedial power does not extend to prospective architectural regulation. Answer: No, the Court will not grant prospective regulatory declarations dictating how service providers structure request validation or error handling.
