Mercury Communications Ltd v Director General of Telecommunications

Ordinary proceedings arising in a public-law setting are not automatically an abuse of process. Although public authorities ordinarily receive the procedural protections of judicial review, Order 53 is not an exclusive procedure. The controlling question is whether the chosen proceedings constitute an abuse.

Where a statutory regulator’s determination becomes part of a contract, the court may determine questions about the proper construction of the governing terms unless the parties conferred exclusive jurisdiction on the regulator. A decision based on a legal misinterpretation does not perform the assigned task. The court may also decide an apparently prospective question where an existing determination and continuing negotiations make the dispute real rather than academic.

Mercury Communications Ltd v Director General of Telecommunications concerned an interconnection agreement between two telecommunications operators. Under the agreement and licences granted pursuant to the Telecommunications Act 1984, the Director General determined the charges payable for connection and call conveyance.

Mercury alleged that the Director had misinterpreted the expressions “fully allocated costs” and “relevant overheads”. It sought declarations by originating summons concerning their proper construction, without seeking to set aside the existing determination. Longmore J in the Commercial Court permitted the summons to proceed, but the Court of Appeal ordered it struck out by a majority.

The central issue was whether the dispute could be raised by originating summons or could only be pursued through judicial review. The House also considered whether construction was committed exclusively to the Director and whether the declarations sought concerned merely academic or hypothetical questions.

Lord Slynn of Hadley delivered the leading speech. Lord Keith of Kinkel, Lord Browne-Wilkinson, Lord Lloyd of Berwick and Lord Nicholls of Birkenhead expressly agreed with his reasons.

1. Disposition. Per Lord Slynn, the appeal was allowed unanimously and the order of the Court of Appeal was set aside. Longmore J had reached the correct conclusion that the originating summons should proceed.
2. Choice of procedure. Per Lord Slynn, the general rule in O'Reilly v Mackman [1983] 2 AC 237 protects public authorities from ordinary proceedings which evade the safeguards of Order 53. Judicial review was not, however, made an exclusive statutory procedure. Exceptions remained to be developed case by case, and the overriding question was whether the proceedings abused the court’s process. The Director’s statutory office and duties under the Telecommunications Act 1984 did not make every related dispute exclusively a matter of administrative law.
3. Contractual character. Per Lord Slynn, the Director’s determination became part of the operators’ contractual arrangements. The dispute was therefore, in substance and form, about the effect of contractual terms, even though it could also be expressed as a dispute about licence conditions. An originating summons in the Commercial Court was at least as suitable as judicial review. The trial judge could take account of the procedural protections ordinarily available under Order 53.
4. Court’s jurisdiction over construction. Per Lord Slynn, clause 29 did not commit the legal interpretation of the governing expressions exclusively to the Director or exclude the court’s jurisdiction. The parties authorised him to apply condition 13 as correctly interpreted. If he misinterpreted its terms, he failed to perform the task assigned to him; if he interpreted them correctly, their factual application might, in the absence of fraud, be beyond challenge. Clause 29.5 also contemplated an appeal or other proceedings.
5. Real and present dispute. Per Lord Slynn, the declarations did not concern wholly academic, hypothetical or merely future questions. The Director had already adopted and maintained an interpretation, while the operators had to negotiate against that position. Mercury’s acceptance of the existing figures while seeking clarification for future dealings created no estoppel and did not rewrite the contract.
6. Strike-out discretion. Per Lord Slynn, a trial judge’s exercise of discretion on an application to strike out for abuse should stand unless the arguments clearly and strongly require a different result. That threshold was not met.
