The firm: Leigh Day specialises in many aspects of national and international personal injury and accident work, human rights, clinical negligence, and multi-party actions. Lawyers at Leigh Day are committed to offering an exceptionally high-quality service to all clients. The firm was set up by Sarah Leigh OBE and Martyn Day in June 1987 to represent individual claimants and their families. This remains the firm’s core value as it continues to grow across all departments.

Types of work undertaken

Personal Injury: The team acts for clients who have suffered severe and often life changing injuries. This includes cases of severe orthopaedic fractures, life changing injuries such as limb loss and brain and spinal injuries and representing a very large number of bereaved families. The cycling team handles hundreds of claims every year and is the exclusive provider of legal support to British Cycling and British Triathlon members.

Industrial Disease: The industrial disease team at Leigh Day not only represent clients who have developed an illness, usually from negligent exposure to asbestos in the workplace, but they also have shaped the law through landmark rulings, including from the Supreme Court, which improve the rights of all negligence victims.

Administrative & Public Law: The firm undertakes a large number of high-profile judicial reviews. The team has successfully challenged the Government over the implementation of Universal Credit and it represented The Campaign Against Arms Trade (CAAT) in its successful challenge against the UK Government for granting licences for arms to Saudi Arabia.

Clinical Negligence: The firm has 30 lawyers representing clients who have been injured, or the families of the deceased, through negligence in a healthcare setting. New head of department Suzanne White is a trustee of the Patients Association and the team works with many other organisations campaigning for patient safety across the NHS and in private practice.

Employment: the employment team at Leigh Day is currently acting for over 40,000 supermarket workers in one of the largest equal pay group claims in history, against the big four supermarkets. The team has also pioneered legal challenges to discriminatory pension schemes in the public sector and is acting for thousands of police officers and hundreds of judges. The team is also involved in claims against Uber and most of the other gig economy employers.

Environment: The firm specialises in claims as a result of exposure to pollution, including radiation, chemicals, pesticides and sewage in the sea. On behalf of Wild Justice, a group led by the naturalist and broadcaster, Chris Packham, the team brought a successful challenge against Natural England over general licences allowing for the mass killing of several species of birds.
The team is at the forefront of the legal fight against climate change on behalf of its clients. It is currently instructed in a challenge to Heathrow’s third runway on grounds that the government failed to consider the Paris Agreement, as well as in a direct action against the Council for the European Union in respect of the damaging CO2 impact of the burning of forests as biomass. They continue to bring judicial reviews of grants of planning permission on air pollution grounds, and we are at the cutting edge of scrutinising the lawfulness of the UK government’s subsidies for fossil fuel projects abroad.

Human Rights: The human rights department offers expertise in special needs education, child abuse, confidentiality and planning. The firm represents the family of Molly Russell, a 14-year-old girl who took her own life in 2017 and the human rights team has been representing Molly’s father in his battle against the social media networks for more disclosure following Molly’s death. The team has an outstanding reputation for its work on medical ethical issues and ‘best interests’ cases. The firm has been ground-breaking in its consideration of the impact of human rights on health and social care law.

International: The firm has pioneered legal developments in multi-party cases on behalf of claimants in the UK and overseas, ensuring that large corporations based in the UK face justice in the UK over the actions of their subsidiaries in developing countries. The firm has also been at the forefront of litigation against the UK Government for alleged human rights breaches arising from the UK’s involvement in overseas military operations and the global ‘war on terror’. In addition, the firm has been at the vanguard of modern slavery litigation. The department’s cases emanate from across globe, in particular Africa, Asia, South America and Europe, with the team providing access to justice to thousands of people who would otherwise go without redress.

The work of the international team has established numerous legal precedents, including Supreme Court authority, on issues as diverse as parent company liability and jurisdiction, the remit of English courts to adjudicate on the UK’s actions overseas, the interplay of UN Security Council Resolutions and the UK’s obligations under the European Convention on Human Rights and the duty of care owed to those serving in the British military abroad. The team’s successes go beyond securing compensation, such as in 2018, obtaining an unprecedented public apology from the UK Government for its role in the ‘detention, rendition and suffering’ of its clients Abdul Hakim Belhaj and Fatima Boudchar.

Product Liability: The department has been involved in some of the most important product liability cases of the last 25 years. Claims include those against manufacturers of home appliances, medical devices, pharmaceuticals, cosmetics and food products. They have also acted on behalf of claimants injured in clinical trials. They acted for the family of Natasha Ednan-Laperouse who died following an allergic reaction. The high-profile case led to a change in the law on ingredient labelling which is now known as “Natasha’s Law”. The team are currently acting as the joint-lead lawyers, in the emissions defeat device group litigation against Volkswagen in the UK believed to be the largest group action in the UK.

The Lex 100 Verdict

Leigh Day is a 'claimant law firm' which is admired for 'acting for people in society who have faced great injustice'. Accordingly, applicants chose the firm for 'its reputation in ensuring justice is not just the preserve of wealthy corporations'. Unlike many other firms, a two-seat training contract is on offer which 'develops individuals' skills to a higher standard'. Conversely, some trainees feel that this hinders their job prospects once they qualify, especially if you 'have  two-year-long seats in areas you do not want to work in'. 'Everyone's motivation to do the best for their clients' stood out to new recruits and many appreciate the 'friendly sociable atmosphere'. Moreover, the 'hours are much better', allowing trainees a decent work/life balance. This is mirrored in the ratings which earned the firm a Lex 100 Winner medal for both social life and work/life balance. In addition to this, Leigh Day is a Lex 100 Winner for job satisfaction, vacation scheme and inclusiveness. Many respondents were happy with the 'responsibility and wide variety of tasks' which make them 'more invested in [their] work'. On the flip side, one respondent commented that 'there isn't the same level of support services as at larger firms' meaning that at times 'a higher proportion of administrative tasks' need completing. But 'the approachability of all staff' and 'how well organised and structured everything is' appeased trainees. The nature of the work at Leigh Day is very rewarding, as best moments included settling claims for 'really grateful and deserving clients'. If you want to work for a firm that undertakes 'challenging and important cases' all 'for a good cause', investigate Leigh Day.
