Simon and Sean discuss the importance of Expert Witness training in the context of Gareth Jenkins' evidence at the Post Office Horizon IT Inquiry and some recent judgments. 

Gareth Jenkins gave evidence to the Post Office Horizon IT Inquiry from 25 to 28 June on the expert evidence he provided on the Horizon IT system. Mr Jenkins told the Inquiry that he had been unaware of his duties as an Expert Witness and had not been offered any training to support his role. The EWI offers comprehensive training on the core competencies of an Expert Witness. We urge policy and rule makers, and the judiciary, to consider how to ensure that Expert Witnesses fully understand their duties and know how to apply them.  

The Post Office Horizon IT Inquiry is currently holding the public hearings for its phases 5 and 6, which will include scrutiny of the expert evidence relied on by the Post Office. We are proud that two members of EWI provided excellent, independent expert evidence or expert advice on the Horizon case. Their roles in the case demonstrate how important it is for Expert Witnesses to understand and apply the core competencies of the profession. 

We’re starting a new EWI series with A spotlight on… the Post Office Horizon Scandal which looks at how the Post Office failed to listen to, and act on, expert advice. EWI member and IT and digital forensics expert, Jason Coyne, first spotted errors in the Horizon system in 2003 while working as a Single Joint Expert, only to have his findings dismissed by the Post Office. Jason tells us more about his involvement in the case, including how he later acted as an Expert Witness in the sub-postmasters’ case against the Post Office.
