Hollie works in the international and group claims department

Hollie joined the firm as a paralegal in July 2021 assisting Oliver Holland within the international and group claims department.

Legal expertise

Hollie has worked on a wide range of cases, including claims against multinationals involving alleged human rights abuses and environmental damage in foreign jurisdictions as well as UK group litigation.

Hollie assists Martyn Day, Oliver Holland and Liberty Bridge in representing over 10,000 Malawian tobacco farmers and their families in respect of claims of forced and child labour occurring on farms allegedly supplying tobacco to British American Tobacco and Imperial Brands.

She further assisted with the settlement of the firms landmark case, Lungowe & Others v Vedanta Resources Limited & Konkola Copper Mines, which involved alleged environmental pollution in Zambia.

Hollie also assists with the firm’s vehicle emissions claims. Leigh Day is currently bringing several claims against vehicle manufacturers following allegations that diesel vehicles had been fitted with ‘defeat’ devices which allowed manufacturers to cheat emissions tests.

Before joining the firm, Hollie volunteered with various human rights organisations including Amicus ALJ and the Freedom Law Clinic. She also assisted in the organisation of a collaborative project between the Environmental Law Foundation, Street Law and the University of Reading focusing on human rights abuses and environmental damage occurring in the fast fashion industry.
