James Hartley
Partner & National Head of Dispute Resolution | Leeds
“James Hartley and Freeths deserve huge credit for taking on this case. What is now recognised as the biggest miscarriage of justice in British history was, at the beginning, a complex and disparate set of stories from individual subpostmasters, about events spanning decades, and in the face of outright denials from the Post Office. Other firms had tried and failed to do what Freeths ultimately achieved. It could not have been achieved without the unfailing commitment of James Hartley to the cause of the subpostmasters, and his unshakeable confidence in the merits.”
