Introduction
Rugby brain injury claims brought by hundreds of former professional and amateur players have reached a critical juncture, with the High Court in England recently asked to dismiss a large portion of the litigation outright. Lawyers for World Rugby, the Rugby Football Union (RFU), the Welsh Rugby Union (WRU), the Rugby Football League and the British Amateur Rugby League Association argued that repeated failures by the claimants’ side to comply with court-ordered disclosure obligations left the court with no option but to strike out the affected cases. The application, if successful, would see 378 claims against the rugby union bodies and 132 claims against the rugby league bodies dismissed before they ever reach trial.
Background to the Litigation
The underlying dispute traces back to 2020, when former players began building claims alleging that the governing bodies breached their duty of care by failing to protect them from repetitive concussive and sub-concussive blows sustained over the course of their careers. High-profile claimants include World Cup winners Steve Thompson, Mark Regan and Phil Vickery, along with former Wales internationals Ryan Jones, Gavin Henson, Colin Charvis, Lee Byrne and Alix Popham.
The players say they now live with early onset dementia, Parkinson’s disease, epilepsy, motor neurone disease and chronic traumatic encephalopathy, and that the governing bodies had access to the scientific knowledge needed to warn them of these risks but failed to act on it. The rugby bodies have consistently denied liability, with World Rugby’s written defence stating that brain injury is a foreseeable and inherent risk of the sport that players accept voluntarily, while disputing that it possessed established scientific evidence linking non-concussive head impacts to long-term neurological harm at the relevant time.

Why the Rugby Brain Injury Claims Are Now at Risk
What makes this phase of the rugby brain injury claims significant is that the dispute has shifted from questions of medical causation to questions of civil procedure. In 2024, the players’ legal representatives were directed to disclose neuropsychological assessments, brain scans and medical reports for each claimant to the defendant bodies. Further orders followed in July 2025, tightening the disclosure requirements and warning that non-compliance could result in claims being struck out. The claimants subsequently lost an appeal against that order, with a High Court judge noting that it followed a serious erosion of confidence in how the disclosure process had been conducted.
At the recent hearing, counsel for the governing bodies argued that, even after these repeated interventions, compliance had still not been achieved across a substantial number of files. Michael Kent KC, representing World Rugby, the WRU and the RFU, described strike out as a measure of last resort but maintained that no further procedural levers remained available to the defendants or the court. William Audland KC, acting for the rugby league bodies, characterised the non-compliance as systemic and without good reason. Susan Rodway KC, representing the players, pushed back firmly, submitting that the breaches were neither serious nor significant when viewed against the scale and complexity of the litigation, and warning that dismissing the rugby brain injury claims on procedural grounds would be a disproportionate outcome for individuals who may otherwise have valid substantive cases.

The Governance and Litigation-Management Angle
Beyond the individual claimants, this hearing highlights a recurring tension in mass tort and group litigation: how courts balance strict enforcement of case-management orders against the risk of shutting out genuine claims on technical grounds. The scale of this litigation, now running into hundreds of individual files with voluminous medical documentation, has strained the disclosure process to its limits. Adding to the turbulence, the claimants’ original solicitors, Rylands Garth, have stepped aside from the case, with the players stating that the change in representation reflects the sheer scale and complexity involved rather than dissatisfaction with the substance of their claims.
For sports governing bodies, the case is also a governance case study in its own right. Institutions such as World Rugby, the RFU and the WRU are being tested not only on player welfare policy but on how litigation of this magnitude interacts with existing dispute resolution frameworks in sport. A strike-out ruling would not resolve the underlying question of whether the governing bodies breached a duty of care to players; it would simply determine whether hundreds of individuals get the chance to have that question tested at trial at all.
What Comes Next
The court has yet to hand down its ruling on the strike-out application, and the outcome will shape the trajectory of the rugby brain injury claims for years to come. If the court sides with the governing bodies, a significant number of claimants could lose their cases without any judicial finding on the merits of their allegations. If it sides with the players, the litigation will continue toward trial, keeping questions about the sport’s historical approach to concussion management firmly in the spotlight. Either way, the ruling is likely to influence how disclosure obligations are managed in future sports-related group litigation, and how far courts are willing to go in penalising procedural non-compliance in cases involving vulnerable claimants and complex medical evidence.
This dispute remains one of the most closely watched pieces of sports governance litigation in the UK, and Offside Legal will continue tracking developments as the court’s decision on the rugby brain injury claims strike-out application is delivered.
