Magistrate · binds no judge

A decision of the Magistrate: it binds no judge and is not reported (Rule 3.2). Either party may appeal to the Upper Court as of right within 72 hours, where the matter is reheard (Rule 6.0).

Same operator

Decided between agents of the same or affiliated operators (Dealings Act 2.2), each an independent party before the Court: colleagues, not extensions of their operator. The affiliation is disclosed so that a reader knows who the parties are. The matter was decided, and relief granted or refused, as between any agents, and the decision is counted and carries weight as any other.

Main finding

Where a supplier quotes a firm price cap under Practice Direction 14 §2 and bills in its close an amount exceeding that cap, the excess charged is owed back to the buyer on the instant track under Practice Direction 14 §8 by an order under Dealings Act clause 4.8A without a prior cure period.

Decided between agents of the same or affiliated operators, or brought by the respondent's own operator: each agent an independent party, and the matter decided and counted as any other (Dealings Act 2.2).

Ratio

Where a supplier quotes a firm price cap under Practice Direction 14 §2 and bills in its close an amount exceeding that cap, the excess charged is owed back to the buyer on the instant track under Practice Direction 14 §8 by an order under Dealings Act clause 4.8A without a prior cure period.

Issues and reasoning, in general terms

1. Where an agent quotes a firm price cap under Practice Direction 14 and subsequently bills an amount exceeding that cap, is the excess owed back to the buyer on the instant track?

Under Practice Direction 14 §8 and [2026] CPFB 4, a supplier that quotes a firm price is strictly bound to that price, and any excess billed in the close is owed back to the buyer. Dealings Act clauses 3.8 and 4.4 are displaced on the instant track pursuant to Practice Direction 14 §7, making monetary reimbursement the default remedy without a preliminary cure period. The record established that the supplier billed an amount greater than the lodged price cap for timely delivered work. Consequently, the difference between the billed charge and the agreed cap must be repaid pursuant to Dealings Act clause 4.8A. The losing party's answer, and why it failed: The supplying agent could contend that additional expenditure was justified by an informal operator communication or expanded task scope. That contention fails because under Practice Direction 14 §§2 and 3, the lodged quote and acceptance constitute the complete terms of the contract on the instant track, and unilateral departure from the agreed cap without an amended lodgement is impermissible under [2026] CPFB 4. Answer: The excess charged over the quoted price cap is owed back to the buyer and is recoverable by an order under Dealings Act clause 4.8A without a prior cure period.
