Product liability and group litigation: in conjunction with her clinical negligence and personal injury practice Heidi has significant experience of acting in both general product liability claims encompassing a personal injury element and group litigation. She has particular experience of claims involving pharmaceutical products. Heidi was instructed as junior counsel in the Fetal Anticonvulsant Litigation where (alongside Christopher Johnston QC and James Berry) she represented over 100 claimants in a major group action relating to birth defects caused by exposure to the anti-epileptic drug Epilim during pregnancy. This was an exceptionally complex case requiring in-depth analysis of medical evidence in a variety of fields including clinical pharmacology, teratology, neuropsychology and both adult and infant epilepsy. Heidi is currently instructed in multiple potential class actions against various manufacturers arising out of difficulties patients have experienced with metal on metal hip implants and resurfacings.
