Undertakes Public Access work

S v Godwin

Lionel is instructed to represent the Defendant (and is being led by Christopher Sharp QC) in a brain and eye injury case proceeding in the High Court in which the Claimant, at the time a minor, was blinded by an airgun that misfired. It is alleged that he lacks capacity due to a brain injury sustained in the accident and an application for the appointment of a deputy has now been made to the Court of Protection. The case is complicated by the Claimant’s complex family history and behavioural issues related to family trauma: there is significant dispute as to the Claimant’s likely trajectory absent his eye injury, as well as the extent to which his prospects are genuinely limited by his condition. The Defendant also disputes that he suffers from a brain injury.


Representing the dependents of a deceased patient in a High Court claim arising out of an 18-20 month negligent delay in diagnosing cancer, which tragically resulted in the patient’s premature death. The claim, which included significant claims for past and future loss of financial dependency, as well as grandparental childcare services, settled for £860,000 at a Joint Settlement Meeting.

Labbadia v Alitalia [2019] EWHC 2103 (Admin)

Successfully represented the Claimant in a High Court claim arising out of his fall whilst descending disembarkation steps at Milan Airport. The case focused primarily on the judicial interpretation of ‘accident’ under the Montreal Convention 1999 (“the 1999 Convention”), namely whether there had been an unusual, unexpected or untoward event, external to the Claimant, causing death or injury, on board an aircraft or in the course of embarkation or disembarkation.

D v NHS CB & R

Successfully defending a claim brought against an ophthalmologist who was alleged to have failed to identify a posterior retinal detachment at two separate examinations, leading to sudden deterioration in vision, emergency surgery and permanent visual defects. Breach of duty, causation and quantum remained in dispute.

Tonkinson v Cavaciuti & Ors

High Court Claim on behalf of dependents of pilot and his wife who tragically died in light aircraft crash in 2015. The primary claim is brought against the constructor, kit and engine providers and Light Aircraft Association in negligence and/or under the CPA; with a secondary claim (adopting the defences of the primary defendants) in negligence (on behalf of the dependents of the wife) against the estate of the pilot. Breach of duty, causation and quantum are in dispute. The parties are due to engage in mediation in the middle of 2019, with the matter otherwise to be listed for a 10-day trial in late 2020.

S v M & Tesco Insurance

Claim on behalf of a man who suffered life-changing injury in a pedestrian road traffic accident. The claim settled for £540,000 at a Joint Settlement Meeting, including significant claims for loss of earning capacity (Ogden 7 calculation), silicon sleeves (to mask the effects of scarring), aids/equipment and domestic and DIY assistance.

E v S & Octagon Insurance

High Court claim on behalf of dependents of a man tragically killed on Christmas Day 2015 in a hit and run accident. The First Defendant was later prosecuted and imprisoned. The claim settled at a Joint Settlement Meeting for £675,000, including significant sums for future loss of financial and service dependency on behalf of his widow, children and father.

B v NWA NHS Trust

Ongoing seven figure claim proceeding in the High Court on behalf of the dependents of a deceased patient following the negligent failure to diagnose cancer.

A v Tagg & Co

Representing the defendant in a case pleaded at £2million proceeding in the High Court. There has already been a successful (contested) application to resile from an admission of liability; and the claim now proceeds with liability, causation and credibility all in dispute.

P & Ors v Germanwings Gmbh; and M & Ors v Germanwings Gmbh

Confidential settlements achieved in two separate High Court claims brought on behalf of dependents of two different families arising out of the Germanwings disaster. There were significant disputes as to jurisdiction, applicable law and quantification, all of which had to be resolved during the settlement negotiations. The terms of the agreements included non-disclosure provisions, which prevent publication of the nature of the settlement achieved.

Gaten v Johnson

£470,000 settlement achieved at Joint Settlement Meeting in which the Claimant had suffered permanent, or semi-permanent, cognitive deficit from a head injury and psychological symptoms arising out of a serious road traffic accident.

Kaur v University Hospitals NHS Foundation Trust

Confidential settlement achieved at mediation in a High Court claim on behalf of the dependants of a deceased patient whose Mantle Cell Lymphoma (MCL) had been diagnosed two years late after negligent analysis of a biopsy. He later developed a blastic variant of the disease that resulted in his early death. Causation and quantum remained in dispute.

Keen v Ashford and St Peter’s NHS Hospitals Trust

Clinical negligence case that settled for a six-figure sum. The Claimant’s sigmoid colon was injured whilst undergoing a hysterectomy, which the surgeon failed to notice. Consequently, the Claimant developed infection; required three additional surgical procedures; and needed to use a colostomy bag permanently after the failure of the final operation to reverse a loop colostomy due to anastomic leakage. Breach of duty and causation remained in dispute. The claim was settled on the basis that the Claimant would not now risk any further surgery and would therefore have permanent disability.

Y v WHH NHS Trust

Obstetric/gynaecological case that settled at close to seven figures. The claimant sustained a second or third degree tear to her anal sphincter as a result of the failure to perform an episiotomy or an operative delivery during the birth of the claimant’s first child. She was left with debilitating colorectal symptoms that significantly reduced her earning capacity, having had to give up a lucrative job due to her inability to work in an office.

S v Secretary of State for Health

High Court claim that settled for a high six-figure sum. The claim arose out of surgical negligence resulting in a permanent frozen shoulder that had caused significantly impaired function. Causation remained in dispute but the claimant’s medical evidence was that he was unlikely ever to return to full function.

R & Ors v C

Confidential settlements negotiated at mediation on behalf of three dependents arising out of a death during the Shoreham Air Disaster. There were disputes between family members as to the existence and/or extent of the dependency of three of these dependents; and their right to be added as individual parties to proceedings. The matter was resolved in their favour during mediation with the conflicted parties separately represented; and individual damages and costs orders negotiated.

D’Souza v West Middlesex University Hospitals NHS Trust

High Court claim that settled for a six-figure sum. The (retired) claimant suffered a damaged popliteal artery during knee surgery that resulted in permanently reduced mobility and independence. Breach of duty and causation were both in dispute. The case settled on the basis that the claimant would, absent negligent surgery, have maintained his independence for the foreseeable future without the need for permanent assistance.

Chatburn & Whitley v Whitley

£365,000 settlement negotiated at JSM on behalf of claimants whose mother tragically died in a plane crash. There were significant dependency claims for loss of child care services to her grandchildren that she had been expected to provide.

Elliott v Light

£382,500 settlement negotiated at JSM on behalf of claimant who suffered from life-changing disability due to the development of Chronic Pain Syndrome and Somatic Symptom Disorder. There was fundamental disagreement between the pain and psychiatric experts as to causation in light of the claimant’s pre-existing medical history; and as to prognosis (whether and to what extent she would recover). The claim settled on the basis that there would only be modest recovery in future.

Holland v Vose

£300,000 quantum settlement negotiated at JSM on behalf of claimant who suffered horrific leg injuries that prevented him from returning to his old work capacity. The settlement figure was reduced to reflect an agreed apportionment of liability.

Westcott v Quirke

£320,000 settlement negotiated at JSM on behalf of a claimant who lost her job as a teacher following the onset of symptoms from asymptomatic pars fractures after a serious motorcycle accident.

Philpott v RG Carter

£320,000 quantum settlement negotiated at JSM on behalf of claimant who suffered disabling ankle injuries and was likely to require full fusion operations on both ankles in the future. The final settlement was discounted to reflect an agreed apportionment of liability.

Labbadia v Alitalia [2019] EWHC 2103 (Admin)

2nd August 2019

Lionel Stride, instructed by Rebecca Smith at Irwin Mitchell, has successfully represented the Claimant in a High Court claim arising out of his fall whilst descending disembarkation steps at Milan Airport. Margaret Obi, sitting in her capacity as a Deputy High Court Judge, was satisfied that this caused ‘an unusual or unexpected event external to him’, constituting an ‘accident’ within the meaning of Article 17 of the Montreal Convention 1999 (“the 1999 Convention”).

De Roeper v NHS Commissioning Board and Ramsay (2019)

27th June 2019

Lionel Stride, instructed by Louise Jackson of Browne Jacobson LLP, successfully represented the Second Defendant in a claim arising out of alleged ophthalmological negligence, which was heard over six days in the Norwich (and Cambridge) County Court. The Court was persuaded that the Second Defendant had acted competently when undertaking an ophthalmic examination at his own private clinic (prior to transfer to an NHS hospital); and that the Claimant had failed to establish that her subsequent retinal detachment could in any event have been diagnosed at either of his two assessments. HHJ Walden-Smith, sitting in her capacity as a High Court Judge, dismissed the claim in a reserved judgment handed down on 27 June 2019.
