Doughty Street Chambers

Work Department


Aswini Weereratne has built a diverse practice in challenging areas.  Her expertise focuses on the protection of the most vulnerable people, children and adults, in society, usually because of mental disability, or abuse and exploitation, through litigation and advisory work with an emphasis on human rights.  She utilises her skills in a wide range of practice areas and cases concerning public and private law issues, welfare and medical treatment cases in the Court of Protection, actions against state bodies, for example, assault and unlawful detention claims, non-recent child abuse claims, inquests and inquiries, reporting restrictions and international law.

Aswini also has extensive experience of investigatory procedures, in public inquiries, inquests, and as independent chair of inquiries, tribunals and professional regulatory bodies.  She has chaired six independent homicide inquiries.  She appears in courts and tribunals at all levels, including the Supreme Court.

Aswini acts for NGOs, government bodies, such as the British Council, and individuals, sometimes through a litigation friend, for example, the Official Solicitor. She is conversant with applications and interventions to international human rights bodies, and before higher courts. She undertakes advisory work including on legislative reform and policy. She has advised lobby groups and parliamentarians on legislation and policy, for example, on FGM. She chaired the mental health and capacity overlap topic group for the Independent Mental Health Act Review chaired by Professor Sir Simon Wessely. She is invited regularly to speak at conferences and events at home and abroad.

She was deputy chair and chair of the Investigating Committee of the General Pharmaceutical Council from 2014 to 2020, and has been a part-time judge of the first-tier Tribunal (Health Education and Social Care Chamber) since 2001, where she is committed to promoting effective participation and access to justice. She is a qualified mediator and is an enthusiastic advocate of alternative dispute resolution and redress mechanisms.
