Criminal Medical Negligence Lawyers

Criminal medical negligence (Arts. 142 and 152 CP) sanctions the professional malpractice of the healthcare worker who, through breach of lex artis ad hoc, causes the death or injury of the patient. The protected legal interest is plural: life and physical and psychic integrity (Arts. 15 and 17 SC), together with social confidence in the healthcare system. Supreme Court doctrine has consolidated that the adverse outcome alone is not enough: it must be proven the breach of objective duty of care, the direct causal link between medical omission and damage, and the objective foreseeability of the outcome according to clinical protocols, practice guidelines and state of science at the time and place of care.

The criminally relevant medical negligence modalities are varied. Diagnostic errors (misdiagnosis, delayed or absent diagnosis causing avoidable worsening or death, omission of indicated complementary tests, failure to perform differential diagnosis with clear symptoms). Surgical malpractice (operating room errors, retained instruments, wrong-site or wrong-side surgery, anesthetic failures, infections from aseptic breach, lack of postoperative supervision). Systemic hospital negligence (nosocomial infections from protocol failure, premature discharge, lack of resources, understaffing, lack of coordination between services). Omission of informed consent (Art. 8 Act 41/2002 on Patient Autonomy) when it causes real damage. Healthcare professional intrusion (Art. 403 CP). And perinatal obstetric negligence resulting in cerebral palsy, hypoxia or birth injuries, particularly sensitive due to the helplessness of the neonatal victim.

The statutory penalties are severe and modulated by the severity of negligence and result. Gross negligence with death (Art. 142.1 CP) carries 1 to 4 years' prison and special disqualification from healthcare profession of 3 to 6 years. Less serious negligence with death (Art. 142.2 CP), 3 to 18 months' fine. Gross negligence with injuries (Art. 152.1 CP), 6 months to 3 years' prison (graduated according to severity of injuries of Art. 149 or 150 CP) and disqualification of 1 to 4 years. Professional negligence (Art. 152.3 CP) carries qualified disqualification. The legal entity (hospital, private clinic, residence, mutual society) can respond as subsidiary civil liability (Art. 120.4 CP) or, in systematic cases, as direct author when failures are organizational. Added is civil liability ex delicto: compensation governed by updated traffic accident scale, can reach hundreds of thousands or millions of euros in serious injuries or death, especially in perinatology.

The technical defense rests on four fundamental axes. First, proof of compliance with lex artis: providing current clinical protocols, specialty practice guidelines, continuous professional training and conformity with state of science at the time of the fact; case-law recalls that lex artis must be evaluated ad hoc, considering available means, urgency, patient condition and professional experience. Second, challenging the causal link: damage must be objectively imputable to medical action; concauses (patient's previous pathology, natural evolution of the disease, lack of therapeutic adherence) exclude or attenuate imputation. Third, independent medical-legal expert evidence: confronting the official report from forensic medical examiner with private experts from the specific specialty (cardiology, gynecology, traumatology, oncology) is usually determinative. Fourth, exhaustive analysis of clinical records, center protocols and prescription logs.

In current forensic practice we observe a significant increase in medical negligence proceedings, driven by greater patient demand, access to medical information, victim associations (Association of Victims of Healthcare Negligence and similar) and the action of the specialized Prosecutor's Office. Act 41/2002 on Patient Autonomy, Act 14/1986 General Health, Act 33/2011 on Public Health, Act 16/2003 on Cohesion and Quality of the NHS, Act 1/2025 on Justice Service Efficiency and consolidated Supreme Court case-law on lex artis and medical liability configure a demanding regulatory framework. At Alonso Sala, with more than 15 years of experience, we approach criminal medical negligence from both perspectives: defense of the accused healthcare professional (proving lex artis compliance, unforeseeability or inevitability of the result, absence of causal link) and private prosecution in favor of the victim (independent medical-legal expert evidence, reconstruction of the causal chain, rigorous compensation quantification by scale). We coordinate with forensic doctors, registered specialists, administrative lawyers (parallel administrative route against public hospitals) and victim associations.
