The state murder trial of Italian-American financier Luca Mangione has entered a new phase with his legal team confirming an intention to pursue a defence of diminished responsibility. The case, which has drawn international scrutiny, is being monitored by a delegation of British forensic psychiatrists as a precedent-setting examination of corporate liability in cases of extreme violence.
Mangione, 54, stands accused of the 2022 deaths of his business partner and two associates in what prosecutors have described as a calculated act of retribution over a failed merger. His defence, however, argues that a diagnosis of paranoid schizophrenia rendered him incapable of forming intent. The trial, now in its third week at the Central Criminal Court in Milan, has seen testimony from seven expert witnesses.
The involvement of British observers stems from a memorandum of understanding between the Italian Ministry of Justice and the Royal College of Psychiatrists. Dr. Eleanor Shaw, a consultant forensic psychiatrist from the Maudsley Hospital in London, confirmed she and two colleagues are attending proceedings as independent observers. "The legal frameworks differ, but the core questions around volition and insight are universal," she stated.
This case marks the first time an Italian court has permitted a psychiatric defence based on a diagnosis of schizophrenia in a corporate homicide context. Legal analysts note that a successful verdict of diminished responsibility could set a new standard for how Italian law treats white-collar crime. Professor Marco Rizzo of the University of Bologna described it as "a watershed moment for Italian jurisprudence."
The prosecution has countered with evidence of premeditation: email records showing Mangione researching offshore accounts and encrypted messaging apps in the weeks before the killings. They argue his actions demonstrate methodical planning incompatible with acute psychosis. The trial is expected to conclude in March.
For the British delegation, the proceedings offer a rare insight into a foreign justice system grappling with complex psychiatric evidence. Dr. Shaw emphasised that her team's role is observational, not advisory. "We are here to learn, not to influence," she said. Their report, to be submitted to the Ministry of Justice, may inform future UK policy on cross-border cooperation in such cases.
The Mangione trial has attracted extensive media coverage, with journalists from 14 countries accredited. Security has been heightened following online threats against the presiding judge. Court officials have declined to comment on security arrangements. The trial resumes tomorrow with closing arguments.
