Dr Tejina Mangat

Call: 1990

Before being called to the Bar, Tejina worked as a junior doctor in Accident and Emergency medicine. She has extensive experience in all areas of clinical negligence and in high value claims. She has been a member of the editorial panel of Facts and Figures, Tables for the Calculation of Damages, since the first edition in 1996. She was Clinical Negligence Junior of the Year in the Chambers UK Bar Awards 2019.

Tejina specialises in clinical negligence. She is ranked by The Legal 500 and Chambers UK as a leading junior in clinical negligence. She acts mainly for claimants and her practice spans the full range of clinical specialisms, though with particular focus on injures of maximum severity, including obstetric and neonatal brain and other neurological injury.

Tejina was named Clinical Negligence Junior of the Year at the Chambers Bar Awards in 2019 and Chambers UK, 2020 describes her as “phenomenally intelligent, very switched on and has an encyclopedic knowledge of medicine and the law.”

Tejina recently acted against Cambridge University Hospitals NHS Foundation Trust for a claimant who sustained a brain injury due to alleged negligence.
