A significant amount of the work Jacqui undertakes involves cases which require the cross examination of vulnerable complainants. Other specialisms include cases which involve the robust challenging of police officers' evidence and cases which rely upon forensic evidence.

Jacqui has experience in a wide range of criminal law cases including large-scale drug cases, multi-handed public order cases, Proceeds of Crime Act (POCA) cases and dishonesty cases. She also has experience in violence and hate crime cases, possession of unlawful weapons, child cruelty, sexual offences and death by dangerous driving. Jacqui's friendly and down-to-earth approach is appreciated by both professional and lay clients.
