Legal 500 2017


Tara specialises in employment, professional discipline, personal injury, and clinical negligence. She has been recommended in the Legal 500 as a rising star and “great courtroom advocate and cross-examiner.”

Tara is regularly sought out for multi-day trials that involve high stake disputes. Clients regularly report feeling calmed by her presence and control in the courtroom, alongside her cross-examining skills of witnesses and experts.

Whilst not afraid to give clear and direct advice, Tara adopts a collaborative approach to litigation; she listens to clients and believes in working as a team to resolve issues commercially and sensitively.

In employment law, Tara acts for employees and employers. She is regularly instructed in complex claims involving employment status, unfair dismissal, discrimination, whistleblowing, and breach of contract. She also appears in the Employment Appeal Tribunal, with several successful appearances in procedural and substantive hearings.

Tara has a particular interest in healthcare-related law and frequently acts for doctors and dentists on instruction from the MDU and DDU. She has been instructed by the British Medical Association and as part of a team on behalf of Dr Eva Carneiro v Jose Mourinho & Chelsea Football Club. She also drafted submissions for the London Ambulance Service for the inquests into the Westminster and London Bridge Terrorist Attacks.

In regulatory law, she acts for dentists, nurses, occupational therapists, and social workers at all stages of fitness to practice proceedings. She also has a keen interest in sport and recently acted for an individual facing disciplinary sanction by the British Horseracing Authority.

In personal injury and clinical negligence, Tara acts for claimants and defendants. She regularly appears in high value claims involving accidents at work and occupiers’ liability, alongside a busy inquest practice. She has extensive experience of claims for and against GPs, secondary-care clinicians, and ambulance staff. She has been seconded to a defendant clinical law team and is well-versed in NHS and MDU/DDU approaches to clinical law claims.

Tara is also a member of the Irish Bar and practises in the Republic of Ireland. She has advised on jurisdictional issues.

Prior to joining chambers, Tara read English Literature & Psychology at Trinity College, Dublin where she was an active member of the debating and Gaelic football teams. She has maintained her love of sport and currently plays football and Gaelic football in London.
