Judgment No. 11193 of April 26, 2024, issued by the Court of Cassation, represents an important occasion for reflection on the issue of building limits and their relationship with supervening regulations, also known as ius superveniens. In particular, the Court expressed its opinion on the need for a concrete analysis of the consequences arising from the application of new regulatory provisions.
The dispute concerned a conflict between G., who had erected a building, and R., who challenged the legality of the construction based on new building regulations. The Court of Cassation reiterated a fundamental principle: the assessment of the restrictive nature of supervening regulations cannot be done in the abstract, but must be carried out considering the specific consequences for the existing building.
Ius superveniens - Restrictive judgment - Concreteness - Necessity - Consequences. In the event of a succession of building regulations over time, the assessment of the restrictive nature of ius superveniens must be carried out not in the abstract, but in concrete terms, verifying the consequences that the builder derives from the application of the new discipline. Therefore, if the latter excludes the principle of prevention by imposing a distance from the boundary, it does not apply to the defendant who, based on such supervening discipline, is required to set back the building.
The headnote expressed by the Court highlights that, in the presence of new regulations, it is essential to consider the specificity of the concrete case rather than applying a general rule. This approach aligns with the principle of concreteness, establishing that new building regulations cannot prejudice already consolidated situations, unless they involve an objective need for adjustment.
Judgment No. 11193 of 2024 represents an important step forward in Italian jurisprudence concerning building regulations and their relationship with property rights. It emphasizes the importance of a concrete and specific analysis of the consequences of new regulations, avoiding rigid applications that could infringe upon already acquired rights. This balanced view between innovation and the protection of pre-existing rights is fundamental to ensuring a just legal system that is adequate to the needs of contemporary society.
