Case study: Post Office miscarriage of justice

Freeths, the legal team who took on the Post Office to successfully fight one of the biggest miscarriages of justice in British history

The Case: one of UK’s most complex and high-profile technology disputes

James Hartley, Dispute Resolution Partner, and the man who launched one of the most significant group actions ever pursued in the UK, against the powerful organisation of the government-owned Post Office Limited – and won.

Over a 14-year period, Post Office Limited criminally prosecuted more than 700 postmasters for theft and false accounting, based merely on information from a flawed computer system called Horizon. As a result, victims were criminally convicted, pursued for debts and made financially destitute; many were also cut off from communities and their whole families were destroyed.

The Freeths’ legal team, led by James, successfully fought and won the legal battle on behalf of the 555 claimant postmasters. Post Office Limited eventually settled the case, issued a formal apology, paid £57.75m in compensation and agreed to implement a compensation scheme for 1,000’s of other affected postmasters. The case also led to a public inquiry and the quashing of hundreds of wrongful criminal convictions.

The Government also agreed in 2022 to implement an additional compensation scheme to ensure that the 555 claimants are properly compensated for having to fight the legal case and incur litigation funding costs which unfairly depleted their recoveries.

"A first-class and extremely competent firm that came to the aid of a major victims' group when all else had failed to expose the truth and when justice had eluded the group for many years. Having failed to find legal support for so long, Freeths took the victims on board and helped to deliver outstanding success with judgments that have changed so many lives."

“As a team, we worked seamlessly all the way through which was key to our success. We are used to handling large complex cases. But in this case there was a big weight on our shoulders because we knew, for these postmaster claimants, it was unthinkable to lose the case. Loosing it would have been devastating for these people because there would be nowhere else for them to go and there would be nothing more they could have done, so it was a big responsibility.”
