The Italian legal landscape is constantly called upon to balance the protection of the territory and compliance with building regulations with individual rights. In this context, the demolition order for illegal constructions represents one of the most incisive sanctions, often the subject of debate and complex jurisprudential interpretations. A recent ruling by the Court of Cassation, judgment no. 23457 of 2025, authoritatively enters this scenario, offering fundamental clarifications on the application of the principle of proportionality in relation to building offenses. This decision, annulling with referral a previous ruling by the Court of Naples of 12/11/2024 concerning the defendant P. P.M., precisely outlines the boundaries within which this principle can operate, distinguishing between the methods of execution of the order and cases of its definitive cancellation. Fully understanding the implications of this ruling is crucial for anyone facing issues of building abuse, whether as a private citizen or as a legal professional.
The demolition order, in the context of building offenses, is not a mere discretionary power of the judge, but a direct and mandatory consequence of a criminal conviction for the construction of illegal works. This imperative character has been repeatedly reaffirmed by jurisprudence and finds its root in Article 44 of Presidential Decree no. 380 of June 6, 2001 (Consolidated Law on Construction), which provides for demolition as a criminal sanction. Its primary purpose is not so much punitive as it is to restore the state of the places, aimed at eliminating the urbanistic and environmental alteration caused by the offense. Ruling no. 23457 of 2025 confirms this approach, emphasizing the "mandatory nature" of the order linked to the conviction. This means that, once the violation of building regulations has been ascertained and a conviction has been issued, the order to demolish the illegal construction follows almost automatically, as a due act to re-establish violated legality.
One of the most debated aspects regarding illegal demolitions concerns the invocation of the principle of proportionality, often also referred to in relation to Article 8 of the European Convention on Human Rights (ECHR) on the right to respect for private and family life. The Court of Cassation, with the ruling by President L. Ramacci and rapporteur G. Noviello, offers a decisive clarification. Ruling no. 23457 of 2025 establishes that proportionality becomes relevant only after the judgment has been rendered and cannot, in any way, lead to the definitive cancellation of the demolition order. To fully understand this distinction, it is useful to read the maxim:
In matters of building offenses, the principle of proportionality, due to the mandatory nature of the demolition order linked to the conviction resulting from the construction of illegal works, becomes relevant only after the judgment has been rendered, to define the most appropriate methods of execution of said order, both with regard to its object, for the exact delimitation of the work to be demolished, and in relation to the temporal aspect, to ensure that the demolition takes place in compliance with the protectable interests that have emerged, relating exclusively to the perpetrator of the offense or the owner and their family unit, whereas cases of definitive cancellation of the demolition order are linked not to the principle of proportionality, but to the adoption of measures legally incompatible with it, such as different forms of regularization or the hypothesis of the correct and effective allocation of the illegally built construction to public use, as per Article 31 of Presidential Decree no. 380 of June 6, 2001.
This passage is of crucial importance. The Cassation Court clarifies that the principle of proportionality does not question the existence of the demolition order, but regulates its implementation methods. The objective is to minimize the impact on the convicted person and their family, ensuring that the demolition occurs in the least detrimental way possible, while maintaining its necessity. This translates into two main aspects:
The ruling therefore emphasizes that Article 8 ECHR, while relevant, cannot be interpreted in a way that paralyzes the effectiveness of a measure restoring urban legality, but only to mitigate its execution methods.
If the principle of proportionality cannot extinguish the demolition order, what are the legal ways for its definitive cancellation? The Court of Cassation is clear: this can only happen in the presence of "legally incompatible measures" with the order itself. These include:
These scenarios represent the only exceptions that can definitively interrupt the effectiveness of a demolition order, not due to a balancing judgment on the severity of the impact on the private party, but due to a changed legal condition of the work itself, recognized by the legal system as a priority or as a remedy for the original offense.
The ruling no. 23457 of 2025 by the Court of Cassation, with its authority and clarity, provides an interpretive framework of great relevance for building and criminal law. It reiterates the rigor with which the legal system addresses building offenses, emphasizing the mandatory nature of the demolition order as an essential tool for protecting the territory and ensuring compliance with regulations. At the same time, it offers a precise compass for the application of the principle of proportionality, confining it to the strictly executive level and not to the cancellation level. For property owners and industry professionals, this ruling is an unequivocal warning to always operate in full compliance with urban planning regulations, as the possibilities of avoiding the demolition of an illegal construction, once a conviction has been issued, are strictly limited to specific and rigorous legal prerequisites, such as effective regularization or the acquisition and public allocation of the property. Relying on expert professionals in urban planning and criminal law is more essential than ever to navigate such a stringent and complex regulatory context, ensuring the correct interpretation and application of these fundamental provisions.
