Case highlights

Case highlights

Mesothelioma settlement including private treatment
Settlement for a man during his lifetime, including private mesothelioma-related treatment. He initially received single immunotherapy as part of a clinical trial but was removed for not meeting the protocol. His oncologist recommended combination immunotherapy, which the Defendant argued was unreasonable because it was not recommended by the client’s NHS treating oncologist. The settlement ensured invoices were discharged by the Defendant’s insurers.
Mesothelioma settlement with future claim rights
Settlement for a 64-year-old client who developed symptoms of mesothelioma. He was working full-time, and we recovered his loss of earnings until age 70 full-time and until age 72 part-time. The settlement also included a provision allowing him to re-open his case if the disease progresses.
Cross-border asbestos claim settled in 7 months
Damages for a client living in Canada but exposed to asbestos in Scotland. I settled his claim within seven months, and his family benefits from bringing claims in Scotland where the definition of dependant includes siblings, spouse, children, and grandchildren.
Complex overalls asbestos case - early judgment secured
A complex “overalls case” where my client was exposed to asbestos through washing her husband’s work clothes. The claim was brought against the husband’s employers, requiring extensive investigation of company accounts to confirm a paymaster. Judgment on liability was entered against the Defendants at an early hearing, and the Court ordered an interim payment.
Successful Claim against Costain for subcontractor exposure
Successful claim for the widow of a self-employed man working as a subcontractor at Costain Ltd’s head office in London. We successfully argued in Court that Costain owed the man a common law duty of care because it supervised the work and provided the asbestos materials.
Compensation for typist exposed to asbestos
Compensation awarded to a typist who was exposed to asbestos while delivering reports to managers.
