First Legal Challenge Launched Against Post Office and Fujitsu Over Horizon Scandal

Lee Castleton, a former sub-postmaster bankrupted by the Post Office, seeks to overturn a civil judgment and claim compensation, spotlighting systemic failures.

Lee Castleton has initiated a High Court lawsuit against the Post Office and Fujitsu, marking the first individual legal action stemming from the Horizon IT scandal.
Castleton was bankrupted in 2007 after being sued by the Post Office for a £25,000 shortfall allegedly caused by the faulty Horizon IT system.
The lawsuit aims to overturn the civil judgment against Castleton, which he claims was obtained fraudulently, and secure compensation for damages.
The Post Office has been stripped of its role in managing compensation for wrongfully convicted sub-postmasters due to delays, with the Department for Business and Trade taking over in June 2025.
The Metropolitan Police are investigating four individuals for potential criminal offenses related to the scandal, though progress is slow due to the complexity of evidence.
