At least eight firms are today facing legal action from around 25 former coalminers who claim they received inadequate compensation under a Government scheme.
The firms facing the claims, thought to be worth around £450,000, in Leeds County Court include Beresfords, Raleys and Saffmans.
North-west firm Mellor Hargreaves is representing the former miners, with professional negligence head Rob Godfrey leading the team. If successful, more claims could be launched.
The original compensation payments were made to miners suffering from vibration white finger under the Coal Health Compensation Scheme.
In 2008, it emerged that firms acting on behalf of miners had brought in more than £700m in fees.
Two Beresfords partners, including name partner Jim Beresford, were later struck off after the Solicitors Disciplinary Tribunal upheld professional misconduct charges made against them (11 December 2008).
