Theo Huckle QC

Theo Huckle QC is Head of our Clinical Negligence and Personal Injury Team at Doughty Street, which includes the team's Product Liability and Industrial Disease work. He was a member of the Welsh Government as the Counsel General for Wales during 2011-2016, a non-elected but ministerial level appointment as the senior advising lawyer to the goverment. I in 2012 Theo was elected a Bencher of Lincoln's Inn, and he was appointed a Visiting Professor of Law at King's College London in 2016.


During his term of office as Counsel General he maintained his common law practice with the agreement of the First Minister of Wales, and is now pleased to return to practice full time and be developing his legal interests further as a member of DSC.  His time as a Law Officer has given Theo a highly strategic approach to complex dispute resolution and team leadership.


2016-17 has provedbeen a busy yeartime for Theo.  With the move out of Government, he took over as General Editor of the Butterworths' Personal Injury Litigation Service (having previously edited and overseen the full rewriting of the primary Division I), co-wrote Apil’s Guide to Noise Claims (Jordans), took over as Head of Team at Doughty Street and accepted the Visiting Professorship. He has also been a regular contributor to Munkman on Employer's Liability (LexisNexis Butterworths) and Occupational Illness Litigation (Thomson Sweet & Maxwell).  He co-wrote Butterworths' original practice manual on the new system for Periodical Payments and has now been asked to lead an update to review the system 10 years on.  He was Times Lawyer of the Week at the end of 2016, and shortlisted as Claimant PI Lawyer of the Year 2017 at the recent national PI Awards.


Theo is also pleased to have been recently invited to become a non-executive board member and trustee of both JUSTICE and Welsh Rowing (he continues to be an enthusiastic sculler) after a long career being at best reasonably competent in a variety of sports.


Theo particularly likes to work digitally/electronically and is pleased to accept instructions entirely free of paper(!).  He has a particular expertise in complex spreadsheet quantum analysis and presentation.  He believes that seriously injured clients should always be visited by counsel in their homes if possible, and that experts should always be firmly tested in consultation before finalising their reports.  If expected to present and argue a schedule of loss in high value cases, he wants to know it inside out and preferably have drafted it himself, or advised in detail upon it before service in its final version.

Professional Negligence

As well as his Medical Claims and Clin. Neg. practice generally, Theo recently conducted two interesting high value Prof. Neg claims against solicitors.

The first is for a project engineer who lost his leg after a construction site accident in Scotland, was advised by his English solicitor that he had to issue in Scotland, and the solicitor withdrew without protecting client's position and with limitation period expiring; Theo agreed to act instructed by Nigel Cook of Cooks and the claim was brought successfully in England against the contractors but settled for 60% because of that limitation risk; the Prof. Neg claim against the first solicitor for the balance of 40% was likewise successfully settled.  

The second case was a claim against the claimant's first solicitor, who allowed the limitation period to expire in one of the Virgin Atlantic beauty therapist cases, of which Theo has handled 6 or 7 to successful conclusions including in 2 High Court trials in 2005: King & Rimmer v Virgin Atlantic [2005]; Evans & Hindmarch v Virgin Atlantic [2011]; Robert Peach of Coffin Mew now instructed as he has done in the rest of that seies of cases and the case was successfully settled at mediation.

Arbitration and Mediation

Theo is a dual qualified mediator (ADR and LSOM) and PIcARBS qualified arbitrator and is a member of the panel of arbitrators.

He has particular experience of ADR in personal injury and family property claims and disputes, and given his broad experience of common law (crime, family, tort, contract) and public law, and his strategic role as a Law Officer at ministerial level in the Welsh Government during 2001-16, is happy to assist with disputes across a broad range of specialisms and also those engaging several legal fields.

Inquiries and Inquests

Theo Huckle QC was during 2011-16 the Counsel General for Wales, a statutory member of the Welsh Government and its senior legal advisor and Law Officer. He joined Doughty Street in 2015 and is a Bencher of Lincoln's Inn and General Editor of the Butterworths' Personal Injury Litigation Service.  

He began practice at the Bar with a broad based common law practice conducting 12 murder defences before specialising in complex disease cases and latterly also public/constitutional cases, and has great experience of advocacy at every UK level including 5 recent Supreme Court appearances, and in many different tribunals from public inquiry to coroner's court to magistrates, county and crown court, to employment tribunal and EAT, to CICA, to committees of both Commons and Lords, and, of course, to the National Assembly for Wales.  He has conducted death-in-custody and child-clinical-negligence inquests, as well as Professor Pennington's 2008 E. coli O157 Public Inquiry.

He is currently advising for an inquest into the death of a handyman, killed when sulphuric acid sink/drain cleaner caused emission of fatal H2S gas, as a precursor to a high value product liability claim for seriously injured family members. Theo has a particular interest in complex medico-legal issues in civil and criminal or quasi-criminal contexts and especially enjoys cross-examining expert witnesses. He is also highly thought of for his empathy with victims of serious/fatal personal injury and their families.
