Mental Illness and Serious Crime: Analysis of the Judicial Response and the Limitations of the Spanish Penitentiary System.

Abstract

Objectives: This article aims to analyse the judicial and penitentiary response to serious crimes committed by individuals with mental disorders, with particular attention to the type of sentence imposed and the indication of psychiatric treatment during its execution.

Material and methods: A descriptive study was carried out, combining a literature review with the analysis of 38 judicial rulings issued in Spain. The study examines the recognition of mental pathology, the corresponding degree of criminal responsibility, and the measures applied. The selected sentences relate to crimes of homicide, murder, and sexual assault, all of which explicitly mention a relevant clinical diagnosis.

Results: The results reveal a clear tendency towards the imposition of ordinary prison sentences, even in cases of diminished criminal responsibility. Only two cases, classified as criminally non-responsible, led to the application of a security measure involving psychiatric institutionalisation. In over half of the remaining rulings, the need for psychiatric treatment was noted, although without specifying how its effective implementation would be ensured. This vagueness, combined with the lack of specialised resources in the prison setting, significantly limits the possibility of appropriate clinical intervention.

Discussion: The study highlights the structural shortcomings of the Spanish penal and penitentiary system in addressing mental health needs, as well as the insufficient coordination between the justice system and the healthcare network. It calls for a more individualised approach that integrates clinical, criminological, and social factors of the offender, and that prioritises rehabilitation over purely punitive logic.
