The long-running prosecution of suspects in the killing of Major Maxwell Adam Mahama has taken a dramatic legal turn after the Court of Appeal set aside the life sentence handed to former Denkyira Obuasi Assembly Member, William Baah.
In a decision with far-reaching implications for Ghana’s jury trial system, a three-member appellate panel held that the jury’s guilty verdict was unsafe, arguing that Baah was convicted on the basis of misdirection and inadmissible evidence.
The panel ruled that the High Court judge, Justice Mariama Owusu, then sitting as an additional High Court judge, gave directions that were “so fundamentally flawed” that the jury’s decision could not stand.
According to the judgment, if the jury had been properly instructed on the law and was guided to disregard certain wrongful pieces of evidence, “they would not have returned a verdict of guilt.”
Incriminating Statements Should Never Have Reached the Jury
A central issue in the appeal was the trial judge’s reliance on cautioned statements by two co-accused persons—statements the Court of Appeal said should never have been considered against Baah.
Such statements, the panel emphasized, were inadmissible against a co-accused and the judge ought to have excluded them entirely when directing the jury. Instead, the Court of Appeal found, those statements were allowed to influence the verdict, creating what the panel called a serious miscarriage of justice.
Legal analysts note that this portion of the ruling could reshape how trial judges instruct juries in complex criminal cases, particularly those involving multiple accused persons.
A Turning Point in the 2017 Lynching Case
The decision represents the most significant reversal yet in the 2017 mob attack that claimed the life of Major Mahama, an officer on duty whose killing shocked the nation and triggered calls for stronger action against mob justice.
In January 2024, Baah and 11 others were convicted at the High Court. Baah was found guilty of abetment of murder, while others were convicted of conspiracy and, for eight of them, the substantive offence of murder.
Two accused persons—Bismark Donkor and Bismarck Abanga—were acquitted entirely.
With Baah’s conviction now quashed, the case reopens debate over the handling of evidence, jury management and the legal thresholds applied in mob-justice prosecutions.
Broader Implications for Jury Trials
The judgment has sparked renewed conversation about the suitability of jury trials in high-profile, multi-defendant cases. Legal watchers say the Court of Appeal’s findings point to gaps in how juries are guided through complex evidence — particularly where the acts of one accused cannot legally be attributed to another.
For many, this latest development underscores the delicate balance between securing justice for Major Mahama and ensuring the strict protection of the rights of accused persons.
