Despite the efforts of Landzo's defence in pleading diminished responsibility at his trial, the ICTY found him guilty of war crimes during the Yugoslavia conflict and sentenced him to 15 years of imprisonment. Although the Trial Chamber found that Landzo suffered from "personality disorder", it rejected this as a mitigating factor under diminished responsibility. The trend repeated itself in further ICTY cases while no importance was attached to the convicted's rehabilitation. Neither the possibility of committing these offenders to an alternative treatment or special regime during their time in prison was ever contemplated. On its side, the ICC has not yet dealt with any case in which this matter was invoked. Even though its regulation has apparently progressed with respect to the ICTY, its effectiveness it is still at question. Besides, the consequences of successfully raising mental insanity remain, at present, a mystery.
