Dublin Corporation v Lowe

Factual and Procedural Background

The Appellant, the local planning authority for The City, commenced proceedings by notice of motion dated 18 May 1999 under section 27 of the Local Government (Planning and Development) Act 1976 (as amended). It sought (1) an order requiring the Respondents to discontinue the alleged unauthorised advertising use of a gable wall at Number 3, Inns Quay, and (2) an order mandating removal of the advertisement hoarding fixed to that wall.

On 4 February 2000 the High Court (Judge Morris) granted relief under paragraph 1 but refused relief under paragraph 2. The Respondents appealed. On 15 May 2001 the Supreme Court allowed the appeal and remitted the matter for a full hearing. After further pleadings, the High Court, on 4 February 2003, dismissed the Appellant’s application in its entirety. The present judgment concerns the Appellant’s appeal to the Supreme Court against that dismissal, confined solely to the requested removal of the hoarding.

The disputed structure is a large advertisement hoarding attached to the first- and second-floor gable wall fronting Chancery Place. Evidence accepted by the courts below established continuous use of the wall for hoarding purposes since the late 1950s, with only brief intervals between successive hoardings. The most recent hoarding was erected by the second-named Respondent on 19 December 1995, four days after the previous hoarding was removed.

Legal Issues Presented

1. Whether the erection of a replacement hoarding on 19 December 1995 constituted a “development” and an “unauthorised structure” under sections 2 and 3 of the Local Government (Planning and Development) Act 1963.
2. If it was a development, whether the works were nevertheless an “exempted development” under section 4(1)(g) of the 1963 Act as “works for … alteration of any structure… which do not materially affect the external appearance of the structure.”

Arguments of the Parties

Appellant’s Arguments

• The 1995 hoarding was a fresh structure erected long after the appointed day (1 October 1964) and therefore required planning permission.
• The works went beyond mere maintenance or exempt alteration; they materially changed the external appearance of the premises and surrounding Georgian streetscape.
• Section 4(1)(g) should be construed narrowly so that wholesale replacement of an advertising structure cannot qualify as exempted development.

Respondents’ Arguments

• The planning “unit” is the gable wall with a hoarding attached; continuous use since before 1964 means the unit itself predates the appointed day.
• Replacing one hoarding with another of identical dimensions is an “alteration” falling within section 4(1)(g) because it does not materially affect the external appearance of the structure or neighbouring structures.
• No material change of use occurred; consequently the works are exempt and no permission was required.

Court's Reasoning and Analysis

Delivering judgment for the Court, Judge McCracken accepted that removing the old hoarding and attaching the new one in December 1995 constituted both “works” and “development.” However, the Court focused on the statutory definition of “exempted development” in section 4(1)(g).

The trial judge’s unchallenged factual findings established: (1) a hoarding had existed on the wall continuously since before October 1964; (2) each successive hoarding was of substantially identical dimensions; and (3) the interval between removal and replacement was only a few days. The Supreme Court agreed that the relevant “planning unit” is the gable wall plus hoarding. Within that unit, substitution of one hoarding for another is an “alteration.”

Interpreting “alteration,” the Court held it extends beyond visual change and can encompass replacement of components, provided the works do not “materially affect the external appearance” within the statutory wording. Because the new hoarding matched the previous one, its installation made no material visual difference; therefore the works satisfied section 4(1)(g). The Appellant’s contention that the Georgian character of the building was offended addressed the presence of any hoarding at all, not the specific 1995 replacement, and was therefore irrelevant to the exemption analysis.

The Court rejected the Appellant’s suggestion that piecemeal replacement of individual components would be lawful while whole-sale replacement would not, describing such a distinction as “unreal.”

Holding and Implications

Appeal Dismissed.

The refusal of an order compelling the Respondents to remove the advertisement hoarding stands. The decision confirms that replacing an advertising hoarding with one of identical size and position can qualify as an exempted “alteration” under section 4(1)(g) of the 1963 Act when the hoarding forms part of a long-standing planning unit. The ruling turns on established facts and statutory interpretation rather than creating new precedent, but it offers guidance on the breadth of “alteration” and the concept of a planning unit in Irish planning law.
