Selected Cases
HMA v MM [2022] – appointed to represent the accused in a complex domestic abuse case where the allegations spanned decades. In addition to the necessary challenges to the admissibility of evidence, careful consideration required to be given to the parameters of the court appointment in light of the accused’s instructions and attitude towards the case.
HMA v AP [2024] – the accused was acquitted at an evidential hearing on the charges of police assault, resisting arrest and acting in a threatening and abusive manner following a challenge to the lawfulness of police action. It was accepted that the police had no lawful authority to place the accused in handcuffs and then into the back of a police van, therefore the accused’s subsequent behaviour was justified in response to the unlawful detention.
