Kirsten Mercer specialises in inquests and regulatory crime.

Kirsten is a highly impressive inquest advocate and has a broad inquest practice, representing a wide array of interested persons in inquests including bereaved families, healthcare providers, care homes, insurers and government departments. With extensive knowledge of coronial law and Article 2 of the European Convention of Human Rights she is frequently involved in arguments regarding the engagement of Article 2.

Kirsten accepts instructions both to prosecute and defend in prosecutions brought by the Health and Safety Executive or Environment Agency.

Kirsten was appointed to the Attorney General’s list of Civil Advocates in 2012 and has ten years of experience representing government departments at inquest. She is particularly well regarded for her handling of matters involving deaths in custody and is sought after in cases where the probation service have been involved in supervising either the deceased or the perpetrator of an unlawful killing. Kirsten is regularly involved in complex and sensitive Article 2 inquests both with and without a jury. She draws strength from her grounding in criminal law, which makes her a natural in front of a jury and from which she has developed a thorough understanding of how to take the best tactical approach to best assist both the inquest and her client.

Kirsten has also been appointed to the Specialist Regulatory Prosecution panel of advocates and prosecutes on behalf of the Health and Safety Executive. She brings that experience to her inquest practice where there is any suggestion of a breach of health and safety legislation. Kirsten is able to provide continuity of representation should any criminal or professional disciplinary proceedings arise out of the issues explored during an inquest.

Kirsten has a keen interest in representing families in cases where there has been a death following or as a result of domestic violence. She is relentless in her desire to ensure such deaths are properly investigated and all evidence is considered by the police and Coroner. She takes on such instructions direct access and often on a pro bono basis to represent families in this type of case. Kirsten has a developing relationship with AAFDA (Advocacy Kirsten also acts for healthcare providers in prisons and more widely.
