Darrel Crilley

Call 1996

"He is very good at putting experts through their paces and is a very careful barrister who is always aware of the legal ramifications."
(Chambers & Partners 2020)

Darrel read Geography at Mansfield College Oxford in the mid 1980’s, proceeded to complete a phD and then switched to studying law at Queen Mary and Westfield College London while lecturing part-time. He obtained a first in law after completing the degree in 2 years. He completed Bar school in 1994/5 after winning a scholarship from the Inner Temple. In the intervening 19 years he has had no regrets about not attempting to stay in academia.

Clinical Negligence

Clinical negligence comprises a distinct and growing part of his practice. He has acted exclusively on behalf of Claimants in this field. His experience spans a wide array of subject matter from routine diagnostic and treatment errors to the misdiagnosis of complex forms of cancer. He brings to this area of practice the cumulative insights of nearly 19 years. He has enjoyed being junior counsel in birth injury claims arising from clinical mismanagement of birth. His experience embraces acting in part 20 claims where the interrelationship between primary tortious damage and supervening clinical negligence is at the heart of matters.

Personal Injury

Darrel is a true specialist in personal injury, clinical negligence and disease litigation with just under two decades of experience in these fields. For the last 10 years his practice has not been diluted by other forms of work. Within this particular sphere he has a truly balanced practice acting for Claimant’s and Defendants in equal measure. He is noted for his willingness to immerse himself in unusual and technically difficult cases as a result of which he is regularly instructed to advise on professional negligence and awkward insurance coverage points.

He has acted in cases involving most kinds of injury over the last 19 years ranging from complex fractures, through chronic pain to more esoteric kinds of damage such as the acceleration of dementia. He has acquired regular experience of managing the outcome on both sides in pain cases. This includes both ‘straightforward’ cases of complex regional pain syndrome as well as more diffuse chronic pain cases wherein moderate or minor injury becomes psychiatrically perpetuated.


Between 4 and 14 years call the core of Darrel’s practice was a specialisation in Employer’s Liability and Industrial disease litigation. He regularly delivered seminars and updates in both areas of work.

During his first decade in practice, he was privileged to receive numerous and consistent instructions in Upper Limb Disorder and HAVS claims. He acquired his knowledge of industrial deafness from the first 6 months on his feet onwards by hard fought battles over Limitation and multi-day trials.

He still regularly undertakes work in this field on behalf of both Claimants and Defendants.

Serious Injury

Over the last 5 years he has consolidated a practice which deals with injuries of the highest levels of severity expected to be handled by senior junior counsel. This experience has comprised:

  • Amputation – He has particular experience of lower limb amputation cases and has advised in several above and below knee cases in the last three years. He is thoroughly conversant with the appropriate experts to procure in such cases. He has advised in loss of upper limb cases and is familiar with the difficult prosthetics arguments they inevitably entail.
  • Polytrauma – Darrel has acted for and against Claimants who have sustained multiple serious injuries. He is now routinely instructed in such matters. He is able to advise on which experts to source and in which order of priority.
  • Traumatic Brain Injury – Increasing seniority has entailed far greater knowledge and experience of traumatic brain injuries than early years practice could ever permit. Competence in dealing with both moderate / severe brain injury and more subtle, mild-moderate cases where the presence of organic cognitive deficits is more debatable can be assumed. Over the last 5 years weekly experience has been gained of dealing with the requisite experts in Neurology, Neuropsychology and neuropsychiatry. Darrel has a particular interest in the issue of mental capacity and its management within head injury litigation.
  • Spinal Injury – Darrel also undertakes work in a range of spinal injury cases involving Cauda Equine, arachnoiditis and complete spinal cord damage. He has been junior in tetraplegic cases and is versed in the complexities of the arguments over suitable care regimes.
