Consumer Council for Postal Services (Postwatch), R (on the application of) v Postal Services Commission & Anor

A regulator’s public determination must be interpreted as a whole, in a common-sense manner, having regard to its accompanying explanatory decision document. Internal material and earlier consultation responses are generally inadmissible where the scheme is intended to be transparent and simple. The formal determination prevails if it cannot be reconciled with the explanation.

Where legislation imposes a duty to make an enforcement order, the regulator cannot refuse enforcement merely because compliance would be unfair or undesirable. Any discretion is confined to the statutory limits. A claimed abuse of power requires conspicuous unfairness, and the court should not pre-empt a regulator’s decision where the statutory decision has not yet been made.

Postwatch sought judicial review of Postcomm’s decision not to take enforcement proceedings against Royal Mail under Postal Services Act 2000, section 22. The dispute concerned paragraph 20(b) of a standards of service compensation scheme, which provided that Royal Mail need not provide compensation where a bulk sender was in default of credit terms without reasonable excuse.

Postwatch argued that the provision permitted compensation to be set off against sums currently owed by the sender. Postcomm and Royal Mail argued that it created a broader exclusion based on the sender’s credit performance during the relevant target year. Postwatch also challenged the suggested reliance on regulatory fairness.

1. Interpretation of the scheme. The determination was a public regulatory document, not a private agreement or enactment. It had to be read as a whole, straightforwardly and in the context of the explanatory Decision Document. The court should be slow to adopt a construction inconsistent with the regulator’s explanation, but the formal determination would prevail if reconciliation were impossible.
2. Paragraph 20(b) concerned a sender who was presently in default of credit terms. It operated as a netting-off provision: compensation could be withheld to the extent that the sender owed Royal Mail money. It did not create an exclusion based on credit performance over the target year. The words “is” and the context of paragraphs 14 to 18 supported that construction.
3. The 80/20 payment standard could be used as an initial indication of whether a sender had a reasonable excuse. It was not determinative against the sender. A sender otherwise entitled to compensation had to remain able to demonstrate a reasonable excuse for the default.
4. The scheme’s purpose was to compensate users for Royal Mail’s poor service, not to penalise account customers for poor credit performance. Any retrospective obligation on senders would have needed to be imposed expressly and clearly.
5. Enforcement and fairness. Sections 22 and 25 of the Postal Services Act 2000 were prescriptive. Where Postcomm was satisfied that a licence condition was being contravened, its duty was to make an order securing compliance, subject only to the statutory exceptions. The limited discretion concerned what provision was needed to secure compliance, not whether compliance should be secured. The broader wording of section 30 confirmed that distinction.
6. Postcomm had not yet made the relevant decision under sections 22 and 25. The court therefore granted declaratory relief on the interpretation of paragraph 20(b), but did not require Postcomm to make an enforcement order or to recalculate compensation. Any subsequent decision would remain subject to judicial review for error of law.
7. The court left open the wider scope of abuse of power. Mere unfairness would not suffice; the suggested threshold was conspicuous unfairness. It was also left open whether abuse of power could prevent performance of a statutory duty.

This was a first-instance judicial review in the Administrative Court. No appellate history was stated in the judgment.
