This experience is particularly valuable when exploring breach and causation in conference with experts.

Inquests and Inquiries
Inquests and Inquiries
Jasmine has a busy inquest practice, to which she brings her previous professional experience of supporting families at the charity INQUEST. She understands the difficulties that families can face when navigating traumatic inquest proceedings and brings a personable and sensitive approach. She is committed to representing families with compassion and tenacity.
A multi-disciplinary practice and background is particularly valuable when it comes to inquests. Her complementary clinical negligence practice means that she is comfortable in inquests involving technical medical issues and has been praised by coroners for her command of the medical evidence. She has recently acted in inquests concerning failures to provide appropriate medication; failures to diagnose; and delays in obtaining treatment. Her professional background in health and social care fields and her current Court of Protection practice both assist in inquests concerning social care or issues of mental capacity and/or mental ill-health.
Jasmine also acts in inquests raising issues of state accountability, such as where the deceased died in prison, police custody, psychiatric hospital or community settings (and including where Article 2 is engaged). Her criminal practice also provides a valuable perspective in inquests involving interaction with the criminal justice system, police or prisons. Her experience as a prosecutor is particularly useful when appearing in front of juries.
Jasmine frequently appears in multi-day inquests, with or without a jury. She has successfully argued for the engagement of Article 2 on a number of occasions and has appeared in a number of inquests which resulted in Prevention of Future Deaths reports.
Jasmine is one of four General Editors of the second edition of Coroners’ Inquests and Investigations.
She is a member of the INQUEST Lawyers’ Group. Jasmine predominantly acts for families but also accepts instructions on behalf of local authorities. She welcomes instructions in respect of public inquiries.
