When procedure silences substance

At first glance the case of Stephen Tonna vs the State Advocate et (First Hall Civil Court (Constitutional jurisdiction) decided on the 11 June 2026 by Judge Henri Mizzi appeared destined to become a hallmark judgment concerning the treatment of vulnerable persons accused of a crime within Malta’s justice system.

The constitutional application lodged by the plaintiff raised profound questions concerning the extent to which persons with intellectual disabilities are capable of participating effectively in criminal proceedings and whether the law provides sufficient safeguards to protect them. Yet, in an unexpected turn of events, the decision delivered by the court never reached the substantive allegations of unfair treatment.

Instead, the court decided to focus on another issue altogether; whether the applicant himself possessed the capacity to institute constitutional proceedings. The judgment exposed an uncomfortable paradox that concerns access to justice.

The plaintiff, a middle-aged man, suffered from severe and permanent intellectual and mental disabilities. According to the facts of the case, the court heard that his condition was so severe that he did not read and write, while his social and emotional development was “stunted”. The man lived with his parents, who assisted him with several daily routines. Additionally, the plaintiff declared that his limitations were documented since 1997. Therefore, the person that stood before the Constitutional Court was not a person with a temporary impairment, but a person whose vulnerabilities were profound, permanent and well documented.

Throughout the case, Tonna built upon these arguments, shockingly claiming that he had failed to understand police summonses that required him to visit the police station for questioning. It was this failure that led to Tonna being charged criminally. He further alleged that the despite his challenges, he was arraigned before the Court of Magistrates and through legal representation entered a guilty plea without actually comprehending the nature or consequences of the proceedings, he was involved in. Protection orders were imposed on him and yet he claimed he did not understand their terms or implications.

The plaintiff also details another occasion where he was interrogated by the police notwithstanding his father informing them of his disability and presenting a medical certificate confirming the same. Furthermore, despite this, Tonna maintained that no accommodations were made to account for his condition and he remained incapable of explaining what had occurred during the interrogation.

The constitutional application filed by Tonna also criticised the legal aid assistance afforded to him. He alleged that the legal aid counsel was appointed the very same day he was supposed to be arraigned before the Court of Magistrates. This, he claimed, gave his legal counsel insufficient opportunity to understand the applications, conditions and complexities of the case. The application stated that psychiatric evidence pointing towards Tonna being not “fit to plead” was presented in court but the latter allegedly refused to examine the report or hear the psychiatrist testimony. The application therefore asserted that the applicant had never been informed of the charges against him in a manner that he could understand them and thus had not effectively exercised his right to legal assistance. This he claimed deprived him of a genuine opportunity to participate in proceedings which found him guilty.

Had the Constitutional Court proceeded to examine the merits of these allegations, it would have confronted several important and largely unexplored questions within Maltese law. Does effective participation in criminal proceedings require more than the formal appointment of legal counsel? Can a guilty plea truly be regarded as voluntary and informed where the accused lacks the capacity to understand its consequences? What safeguards must police authorities adopt when dealing with intellectually disabled suspects? To what extent should Maltese courts draw inspiration from Malta's obligations under the UN Convention on the Rights of Persons with Disabilities (UNCRPD), particularly the requirement to ensure effective access to justice through procedural accommodations? These were not merely academic inquiries. They touched directly upon the practical operation of the criminal justice system and its capacity to accommodate those who are least able to navigate it independently.

Yet none of these issues were ultimately determined.

No judicial pronouncement

Rather than addressing whether Articles 5 and 6 of the European Convention on Human Rights or Articles 32 and 39 of the Constitution had been infringed, the court upheld a preliminary objection raised by the parte civile and declared the application null. The court upheld the first plea of the co-defendant, Thea Calleja, that Tonna was not capable of filing the action.

The court concluded that the evidence demonstrated that Tonna suffered from a mental disorder or condition rendering him incapable of managing his own affairs and that the constitutional proceedings had consequently not been instituted through the proper procedural mechanisms. This resulted in the constitutional proceedings coming to an end without any judicial pronouncement on the substantive allegations of human rights violations.

The outcome of the case is ironic. Stephen Tonna’s complaint was founded upon the argument that his intellectual disability prevented him from participating meaningfully in criminal proceedings and deprived him of the protections required by a fair trial. Yet the Constitutional Court effectively accepted that same vulnerability as the reason why the constitutional proceedings themselves could not validly proceed. The disability which allegedly denied him effective participation before the criminal courts became the disability which prevented the constitutional court from examining whether those alleged violations had in fact occurred.
The paradox raises broader questions concerning access to constitutional redress in Malta. Procedural safeguards undoubtedly serve important functions, so much so that rules governing legal capacity exist to protect vulnerable individuals from prejudice and exploitation. Nevertheless, if those same procedural requirements operate in such a way that they prevent judicial scrutiny of serious allegations concerning fundamental rights, one must therefore ask whether the legal framework adequately protects the very individual it seeks to shield. If vulnerable persons cannot effectively defend themselves in ordinary criminal proceedings and cannot independently pursue constitutional redress when those proceedings allegedly violate their rights, what mechanisms exist to ensure their grievances are substantively heard?
Stephen Tonna’s case invites reflection on whether Maltese procedural law sufficiently accommodates litigants with intellectual disabilities.

Ultimately, Stephen Tonna vs the State Advocate is remarkable not because it resolved the difficult questions surrounding vulnerable accused persons, but because it left them unanswered. The court’s ruling transformed what initially appeared to be a landmark judgment on fair trial rights and disability into a decision concerning procedural capacity and access to constitutional remedies. The case reminds us that justice is not measured solely by the rights enshrined within constitutions and conventions, but also by the ability of those most vulnerable to invoke them. The enduring legacy of this case may therefore lie not in what the court decided, but in what it was unable or possibly unwilling to decide.
