Cork County Council & Ors v Slattery Pre Cast Concrete Ltd & Ors

Factual and Procedural Background

Slatterys Pre-Cast Concrete Limited ("Slatterys") operated a concrete business near Rathcormac village, County Cork, originally focused on pre-cast concrete products and later expanding significantly into ready-mix concrete. The business grew from a small operation in the late 1990s to a large-scale enterprise covering approximately 12.5 acres, far exceeding the original planning permission granted in 1997 for a 0.9-acre pre-cast concrete facility.

Cork County Council ("the Council") initiated proceedings alleging breaches of planning law under section 160 of the Planning and Development Act 2000 ("the 2000 Act"), contending that the scale and extent of the business exceeded the scope of the original permission, rendering much of the site’s structures and use unauthorised. Individual plaintiffs also brought proceedings on similar grounds and additionally claimed nuisance caused by noise, dust, and road damage resulting from the business’s expansion.

The Council issued warning letters following inspections in 2005 and received multiple complaints from local residents from 2003 onwards. Slatterys applied for retention permission in 2005, which was refused by An Bord Pleanála ("the Board") in 2007 due to adverse environmental and amenity impacts, including visual intrusion, noise, traffic hazards, and effects on residential properties.

Subsequently, Slatterys engaged consultants and solicitors to prepare revised planning applications, but the Council proceeded with enforcement actions. The proceedings focus on whether the unauthorised development is enforceable given statutory limitation periods and the extent of the breaches, including intensification and extensification of use, and the erection of unauthorised structures.

Legal Issues Presented

1. Whether the relevant limitation period for enforcement under section 160 of the 2000 Act is five or seven years.
2. Whether the unauthorised developments, including intensification of use, extensification of land, and erection of structures, occurred within the limitation period and are thus enforceable.
3. Whether the intensification of use of the site constitutes a material change of use requiring planning permission.
4. The proper approach to incremental or gradual intensification of use in the context of limitation periods.
5. The extent and exercise of the court's discretion in granting enforcement orders or relief.
6. The question of nuisance arising from the business operations and whether injunctive relief is appropriate.

Court's Reasoning and Analysis

The court first determined that the relevant limitation period under section 160(6) of the 2000 Act is seven years, extending the previous five-year period. This extension was not considered retrospective legislation as it merely prolonged the period during which enforcement proceedings could be brought for ongoing unauthorised developments.

The court then analyzed the state of the business as of July/August 2000, the critical date for limitation purposes. It found that while the batching plant structure was largely in place by that time, it was not yet fully operational. The ready-mix concrete production was still ancillary to the pre-cast concrete operations and had not reached a scale constituting an independent use requiring separate planning permission.

The court distinguished three categories of unauthorised development: (a) intensification of use (significant increase in heavy goods vehicle traffic and related environmental impacts), (b) extensification (incorporation of additional land without permission), and (c) erection of unauthorised structures. It concluded that intensification sufficient to amount to a material change of use occurred after July/August 2000, while extensification and structures in place before that date are statute barred from enforcement.

In assessing intensification, the court applied established principles that a material change of use arises when the nature or character of the use alters significantly, particularly regarding planning and environmental impacts such as traffic volume, noise, dust, and visual amenity. It found that more than 15 heavy goods vehicle round trips per day constitutes a material change of use and is unauthorised without permission.

The court rejected Slatterys’ argument that natural growth or evolution of the business permitted continued unauthorised use, emphasizing that such principles apply only to lawful uses or properly interpreted permissions. Unauthorised structures and expansions beyond the limitation period remain unlawful, though enforcement is barred.

Regarding discretion, the court noted it should be sparingly exercised and considered Slatterys’ reckless disregard of planning laws, refusal of professional advice, rejection of retention applications, and continued unauthorised expansion despite warnings. The court declined to exercise discretion in Slatterys’ favor and proposed enforcement orders within the bounds of the original permission and limitation period.

On nuisance, the court acknowledged past nuisance but found remedial measures had reduced ongoing nuisance. It declined to grant an injunction at this stage, leaving plaintiffs liberty to apply for injunctive relief if nuisance continues after enforcement orders are implemented.

Holding and Implications

The court’s final decision includes the following core rulings:

• Enforcement proceedings are barred by limitation in respect of unauthorised structures and land use incorporated before July/August 2000.
• Unauthorised intensification of use exceeding 15 heavy goods vehicle round trips per day and ready-mix production exceeding 50% of total production are not statute barred and subject to enforcement.
• Orders will be made requiring removal of unauthorised structures erected after July/August 2000, cessation of use of lands outside the authorised boundary, and limitation of use to no more than 15 heavy goods vehicle round trips daily and ready-mix production not exceeding 50% of total production.
• No discretion will be exercised to permit continuation of unauthorised development beyond these limits.
• Damages for past nuisance are awarded to individual plaintiffs, with quantum to be determined later; injunctive relief is deferred pending observation of compliance with planning orders.

The direct effect is that Slatterys must immediately cease unauthorised expansions beyond specified limits and remove unauthorised structures erected after the critical date. No new precedent was set beyond application of existing planning law principles and statutory limitation provisions.
