This study deals with the principle of the inviolability of the home, guaranteed by the 1988 Federal Constitution, and the legal consequences of unauthorised entry into homes. Violation of the home is an issue of great legal and social relevance, since it directly affects individuals' rights to privacy and intimacy. The main aim of this paper is to analyse unauthorised entry from the perspective of the principle of inviolability, investigating the legal implications and the situations in which the invasion can be considered legitimate. To this end, the study considers the exceptions provided for in the legislation, such as cases of flagrante delicto, disaster or rescue. The methodology adopted was based on bibliographical research, of a qualitative nature, using the deductive method to explore doctrine and case law dealing with the subject. Based on these sources, the work offers a critical analysis of the balance between the protection of individual rights and the needs of public safety. It concludes that, although there are legal exceptions to home entry, the application of these exceptions must be strictly controlled to avoid abuses and ensure that fundamental rights are preserved. The study also emphasises the importance of judicial control as a way of ensuring respect for due process of law.
