Jonathan Zimmern, Partner, Fieldfisher

Jonathan deals with complex, high value medical negligence cases covering all of areas of medical treatment including birth injury, delayed diagnosis, surgical negligence, brain injury, spinal injury, nursing care, inquests and orthopaedic injury. He is a member of the Association of Personal Injury Lawyers and is acting on behalf of the Trustees for the vCJD compensation scheme, which manages £67.5m for victims of variant Cruetzfeldt Jakob Disease and their families.

He has particular expertise in dealing with complicated cases of clinical negligence which overlap with pre-existing personal injury claims and is regularly instructed by clients to take over cases that have been mishandled by other solicitors.

He has recently appeared in the Court of Appeal in a potentially ground breaking case which considered the legal duties of care that clinicians might owe to relatives of patients who they are treating for genetic conditions. His court of appeal case was reported in the Times, 27.11.15 and Daily Mail, 28.11.15, and he was invited to contribute to Radio 4 "Inside the Ethics Committee" programme.

Jonathan has dealt with a number of high profile cases which have been reported in the national or regional press, including a claim for a 13 year old girl left quadriplegic after a routine spinal operation. The case was covered in the national press and by regional news broadcasters. Click the links below to find out more.
