Group Action Defence Solicitors

We advise commercial organisations, public bodies, sports organisations, financial institutions, regulated businesses and insurers on the defence of some of their most sensitive disputes. Our group litigation experience covers standalone claims and complex litigation involving thousands of claimants, multiple defendants and significant public scrutiny.

Examples of our expertise

Injury claims

We routinely defend businesses and organisations against organised claims for collective redress by employees, customers, the general public or participants including catastrophic incidents, travel claims and sports.

Large scale incidents

Weightmans has experience in defending claims arising out of large scale incidents.  Our multi-disciplinary approach facilitates a seamless service from representation in criminal prosecution to civil actions from affected parties. 

Following a large scale explosion caused by the illegal acts of a third party, we represented the gas supplier in a post-incident prosecution and subsequent civil claims by a number of innocent third parties alleging injury and property damage. Our regulatory and casualty teams worked together to address complex and technical issues of liability, causation and loss.

Occupational diseases

Weightmans acts on behalf of long tail insurers in respect of public and employers liability risks.                                

We have extensive experience acting for insurers and corporate employers in a range of matters including HAVS exposure, asthma and deafness litigation with the leading authority for NIHL in textile workers, Baker v Quantum Clothing Group Limited and others [2011] UKSC 17 , which addressed issues of foreseeability, breach of duty and historical standards of knowledge regarding occupational noise exposure. 

We are trusted to act in sensitive matters and our experience includes acting on behalf of an airline in a complex group action arising out of alleged facilitation of military activity.

Our specialist teams have the experience to deal with emerging risks such as Q fever, acting in a group action arising out of the first significant outbreak in an industrial setting in the UK. Addressing complex issues with expert investigation involving engineers, occupational hygienists, microbiologists and medical experts in a claim asserted at over £1m, we were able to secure a significant reduction in outlay on damages and costs, with successful recovery of a contribution from contractors carrying out renovation works.

Sports

Weightmans’ specialist sports team has unparallelled experience in advising governing bodies, clubs, organisers of sports and their insurers and brokers in respect of complex claims. Our multi-disciplinary, national team means we have the expertise to advise on all areas of a dispute, providing technical knowledge, pragmatism and commercial understanding. Our experience in group actions includes acting on behalf of major sporting bodies and insurers in high profile claims for long term neurodegenerative disease brought by over 700 professional and amateur sportsmen and women.

Data Breach and Multi-Claimant Privacy Claims

Our technology and cyber team has extensive experience in incident response and claims management arising out of cyber events and data loss. 

We have advised one of the UK's largest academy trusts following a ransomware attack affecting more than 30,000 data subjects and supported international organisations responding to sophisticated cyber-attacks involving sensitive personal data.

Environmental and Nuisance Collective Claims

We have experience in the defence of toxic tort class actions involving landfill operators, biofuel producers, waste treatment facilities, chemical manufacturers and nuclear operators. The cases have involved allegations of negligence, nuisance and Rylands v Fletcher, as well as breaches of various statutory duties.  In these cases, costs issues played a central role in the tactics of both sides. To successfully defend them, we worked hand in hand with our costs lawyers with their detailed knowledge of litigation funding and costs issues.  Reputational exposure and “copycat” claims are key things to be avoided, and we managed both successfully in reaching settlements.

Abuse and Multi-Claimant Litigation

Our work includes advising charities, educational institutions, public bodies and insurers on complex and sensitive claims involving multiple claimants, media scrutiny, reputational issues, safeguarding considerations, human rights arguments and data protection concerns.  We have the skills, experience and resources to deal with the demands of such actions including consideration of large volumes of documents and records. Our specialist lawyers have experience in dealing with compensation schemes and redress arrangements, understanding the complexities of management and containment of costs in such matters.

Social Housing claims

We have extensive experience providing legal services in the social housing sector, offering strategic, practical and innovative solutions to registered providers facing a variety of group action claims.  Our multi-disciplinary teams understand the unique challenges facing the sector. We are specialists in acting on behalf of housing providers defending complex group actions in relation to alleged defective premises and works, including fitness for human habitation and Awaab’s Law claims and housing conditions class actions involving allegations of negligence, nuisance and damages.

Financial and Taxation Mass Claims

Our experience includes acting on behalf of importers appealing retrospective duties imposed by HMRC in the tax tribunal, in litigation arising from the British Steel pension transfers, and advising insurers on claims linked to high-profile investment and financial products litigation.

Complex Multi-Stakeholder Investigations and Proceedings

Weightmans represented ten doctors in a long-running regulatory matter considering the application of Article 8 ECHR, GMC guidance and privacy involving multiple institutional clients, numerous stakeholders and appeals processes.

Employment

Our employment, pensions and immigration team has extensive experience in defending complex group and collective claims for major employers and public bodies.

We represented a national transport and logistics client in defending more than 6,000 holiday pay claims arising from a national industrial relations dispute. We have also acted for a local authority in relation to more than 2,000 claims under the Working Time Regulations.

In such matters, we work with the clients to design bespoke workflows, reporting arrangements and innovative pricing models to manage the claims consistently and efficiently at scale. This reduces the operational and managerial burden on the clients, provides cost certainty and enables claim to be resolved successfully while maintaining strategic oversight throughout.

Healthcare
