Building Demolition Order: The Court of Cassation and the Sufficiency of the Structure's Dimensions (Judgment No. 24720/2025)

Italian building law is constantly subject to jurisprudential interpretations that refine its application. The recent judgment of the Court of Cassation No. 24720 of 2025, filed on July 7, 2025, addresses a crucial issue for the fight against illegal construction: the specificity of the demolition order. This ruling, with rapporteur Dr. A. S. and president Dr. L. R., clarifies what is actually necessary for the execution of an order to demolish an illegal structure in criminal proceedings, providing valuable guidance for professionals and citizens.

The Nature of the Demolition Order and the Regulatory Context

The Italian legal system combats illegal construction with both administrative and criminal tools. Presidential Decree 380/2001 (Consolidated Text on Construction) is the key legislation, providing in Article 31, paragraph 9, for the demolition order as an accessory penalty to a conviction for building offenses (Article 44). This order aims to restore legality. The precise identification of the structure to be demolished has often generated debates, particularly regarding the need for detailed indications such as cadastral data. The issue also arose in the case of the defendant E. M., prompting the Supreme Court to provide clarification.

Judgment No. 24720/2025: Crucial Details and Findings

The Court of Cassation, with judgment No. 24720 of 2025, offered a pragmatic solution. The core principle is expressed in the following maxim:

In matters of building offenses, the mere indication of the dimensions of the illegal structure to be demolished is sufficient, in criminal proceedings, to ensure the precision and specificity of the demolition order, as a complete description of the illegal works through cadastral data is not necessary for its execution.

This ruling is of fundamental importance. The Court, with Dr. L. R. as president and Dr. A. S. as rapporteur, establishes that, for criminal proceedings, an excessively meticulous level of detail is not required to identify the illegal building. The "mere indication of dimensions" (e.g., length, width, height, or area) is sufficient to meet the requirements of precision and specificity of the demolition order. This means that authorities are not obliged to provide detailed descriptions based on cadastral data, which are often absent for illegal constructions. The objective is to simplify the execution of the order, preventing delays or impediments to the restoration of legality. This line is consistent with previous case law (e.g., No. 21198 of 2023 Rv. 284627-01), which prioritizes substance over form, provided that the identification of the property is unequivocal for the recipient and the executors of the order.

Practical Implications of the Decision for Citizens and Authorities

The consequences of this judgment are significant:

• For Property Owners: A demolition order is valid and enforceable even without cadastral data, provided the dimensions of the illegal structure are clearly indicated. Greater vigilance on the regularity of one's constructions is necessary.
• For Authorities: The ruling streamlines the issuance and execution of demolition orders. Exceptions of vagueness based on the absence of cadastral data will no longer be admissible, provided that dimensional identification is sufficient. This makes the repression of illegal construction more efficient.
• For Legal Professionals: It is essential to update defense and advisory strategies, as formal exceptions related to cadastral descriptions lose their effectiveness if dimensional identification is adequate.

The decision reinforces the principle that the demolition order, as an accessory criminal penalty, must be practically enforceable and aimed at restoring urban legality, avoiding superfluous formalities.

Conclusions

Judgment No. 24720 of 2025 by the Court of Cassation is a fundamental clarification for case law on building offenses. By affirming the sufficiency of merely indicating dimensions for the validity of a demolition order in criminal proceedings, the Supreme Court enhances the effectiveness of actions against illegal construction. This decision emphasizes clear identification of the structure, prioritizing practicality and ensuring precise and specific orders without excessive bureaucratic burdens. It is an important reference for all stakeholders in the sector.
