Cat McGarrell

Bringing her expertise in group litigation, Cat joined Gilson Gray to establish our volume claims department with Head of Litigation Rosie Walker, where they will progress claims on behalf of pursuers arising from mass GDPR breaches, PCP vehicle financial mis-selling, and other multi-pursuer litigations.


Cat’s background in group actions began with a case-holding of complex medical product liability cases, including claims arising from the PIP breast implant scandal (litigated in Scotland’s Court of Session and multiple French courts), polypropylene vaginal mesh, and cases arising from the historic infected blood scandal. Her caseload also comprised of highly sensitive litigation, including mass claims arising from the baby ashes scandal, and historic childhood sexual abuse.

In 2020 she raised Scotland’s first ever group action under the Chapter 26A Group Proceedings Rules. She was also instrumental in her previous firm’s litigation of Scotland’s second and third group actions; the Kenya Tea cases and the Celtic Boys Club cases respectively.

Cat will also be representing the interests of Homeless Network Scotland (HNS) in the Scottish Covid-19 Inquiry. HNS are umbrella organisation of some 40 housing and homelessness organisations, including Social Bite, Shelter, and Crisis.
