To admit or not to admit: a comparative constitutional perspective on illegally obtained evidence in Ghana

During criminal investigations, law enforcement agents sometimes flout the law. They extract evidence by torture, illegal wiretapping, unlawful searches and seizures among other illegitimate means. In the United States, such illegally (or improperly) obtained evidence is inadmissible in criminal trials subject to some exceptions. The reverse position generally obtains under English law. In Ghana, because the Supreme Court has yet to make a definitive pronouncement on the issue, conflicting viewpoints exist. In this article, we analyse the relevant constitutional, statutory and case law principles with the view to clarifying the admissibility or otherwise of illegally obtained evidence in Ghanaian courts.
