Habeas Corpus

Abstract

The article analyzes the legal nature of habeas corpus and its effects on criminal proceedings, with the aim of clarifying in which situations the granting of the writ entails, or does not entail, the termination of criminal prosecution. It adopts a legal-doctrinal methodology based on the interpretation of the Code of Criminal Procedure, especially articles 648 and 651, on the examination of criminal procedural scholarship, and on the discussion of case-law examples concerning the admissibility of the writ. It argues that habeas corpus generally has the nature of a criminal action, only exceptionally assuming a procedural appellate character, and that its classification as a precautionary, constitutive, or declaratory action depends on the specific judicial protection sought. The article shows that termination of proceedings occurs when the writ is grounded on causes extinguishing punishability, absence of factual support for prosecution, abolition of the offense, absolute atypicality, or other hypotheses in which the writ affects the procedural legal relationship itself, whereas no such termination occurs when the measure merely removes unlawful precautionary constraints, such as undue preventive detention or an irregular arrest in flagrante, without preventing the continuation of criminal proceedings. It concludes that habeas corpus is a multifunctional procedural instrument for the protection of liberty, whose effect on the course of proceedings depends on the nature of the claim asserted and on the legal basis of the challenged coercion.
