It is a settled principle in Maltese administrative law that the Court of Appeal in planning cases may only intervene “on a point of law.” This jurisdictional threshold reflects a careful constitutional balance: while the Environment and Planning Review Tribunal may evaluate facts, context, and visual integration, the Court must respect its discretion—unless that discretion exceeds the bounds of law.

But how does one recognise when the Tribunal has crossed that line? Din l-Art Ħelwa v Planning Authority and Karkanja Ltd (App. No. 53/2024) provides an instructive case study.

The Tribunal had approved a substantial residential development in Triq Santa Katerina, Xewkija, comprising multiple floors and a deep rear extension. In doing so, it relied on aesthetic considerations and the cultural value of a historic arched room, citing Article 72(2)(d) of the Development Planning Act. It treated the stepped design, architectural rhythm, and the Superintendence’s non-objection as sufficient grounds for departing from three operative policies: P26 (frontage width), P27 (depth), and P35 (height).

But these were not flexible guidelines. They were hard-edged rules. Policy P27, for instance, permits rear depths greater than 30 metres only when both adjacent sites also exceed that limit. The Tribunal did not confirm whether this was the case. Likewise, Policy P35 set an unqualified height cap. And yet the Tribunal treated these policies as though their application could be waived by general considerations of good design.

The Court intervened. It did not reweigh visual arguments. It confined itself strictly to law. It found that the Tribunal had misapplied fixed thresholds and failed to establish the factual predicates required to depart from them. Most critically, the Tribunal introduced planning considerations—such as architectural coherence and heritage value—that the policy structure had not authorised as grounds for exception. This, the Court held, was not within its legal competence. The Tribunal may interpret; it may not override.

This is precisely how a point of law is spotted. It emerges when a Tribunal treats legal conditions as though they are aesthetic choices. When a policy demands prior verification (such as the width or depth of neighbouring sites), the Tribunal must obtain and assess that evidence. When a policy does not permit deviation, none is possible—even in the name of design logic.

Put simply, there are policies that invite evaluation—and there are policies that impose thresholds. When the Tribunal confuses the two, its decision ceases to be discretionary and becomes unlawful.

The Court in Din l-Art Ħelwa v Karkanja did not deny that heritage value matters. But it held, correctly, that such considerations must operate within the policy framework—not in defiance of it. The legal error was not in the Tribunal’s motivation. It was in its method.

That is the essence of the “point of law” doctrine. Not a question of taste, but of threshold.
