Birmingham City Council v Persons Unknown

A final injunction with continuing effect may be varied to reflect a genuine change of circumstances and preserve its original purpose. The court must distinguish such a variation from the grant of new relief for a new claimant based on a legally distinct cause of action. Final orders are not a vehicle for rolling relief. Where a public authority seeks protection for a different geographical area and different local interests, the proper course is fresh proceedings, particularly where the injunction was obtained without notice and breach may lead to imprisonment.

Birmingham City Council obtained a three-year injunction restraining street cruising in its area. North Warwickshire Borough Council later applied to be added as a claimant and sought to extend the injunction to North Warwickshire, relying on the continuing street-cruising problem, cross-border roads and enforcement convenience.

The application was made eighteen months after judgment. The central issues were whether North Warwickshire could be joined and whether the final injunction could be varied under the Civil Procedure Rules, or under the court’s inherent jurisdiction, to grant relief protecting a different authority’s area and inhabitants.

1. Jurisdiction and statutory standing. Local authorities may bring proceedings under section 222 of the Local Government Act 1972, assert and protect public highway rights under section 130 of the Highways Act 1980, and rely on their geographically defined statutory functions. The High Court’s injunction jurisdiction under section 37 of the Senior Courts Act 1981 is broad, but remains subject to proper procedural limits.
2. Continuing injunctions. An injunction with continuing effect may be varied during its lifetime where circumstances change, including where variation is needed to preserve the order’s intended effect. Harrods Limited v McNally [2013] EWHC 1479 (QB) illustrated that principle. A variation may, for example, adjust an affected area within the original claimant’s jurisdiction.
3. Limits of variation. The proposed order was materially different. It would add a new local authority and grant new relief for crime, nuisance and inhabitants in a different geographical area. Those matters were not in dispute when the original judgment was given. The application therefore sought substantially new relief, not merely an adjustment preserving the original order’s purpose. The connected practical and geographical circumstances did not make the causes of action legally identical.
4. Finality and procedural caution. Final orders are not lightly reopened and proceedings should not become a source of rolling relief. The exceptional without-notice procedure, the absence of adversarial argument and the possibility of imprisonment for breach required caution. The absence of prejudice to affected persons did not justify stretching the procedural rules.
5. Disposition. Even if the court had jurisdiction under CPR Parts 3.1(7) and 19.2, it would not exercise its discretion to join North Warwickshire or vary the injunction. North Warwickshire’s proper remedy was a fresh claim, which the judge indicated would be favourably considered.
