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 pilot project seeks to use a range of highly expert consultants from a range of specialties undertake assessments of children, discuss findings with one another, and write a formal report for the Family Court.

An expert report did not address all of the questions posed in the letter of instruction, reformulated other questions, and failed to comply with FPR Part 25 in a number of important ways, while the expert witness's oral evidence failed to provide an impartial expert view. 

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. 

Welcome to Expert Matters, the official podcast of the Expert Witness Institute. Each month, we'll be taking an informed look at the key developments in the world of expert witnesses and expert evidence.

An expert opinion must be supported by reasoning and correctly apply the relevant legal tests. 

The report of the psychiatrist expert witness strayed outside his expertise. It did not show any clear independent knowledge, demonstrate that that he was a country expert, or provide supporting source material.

This case update gives useful guidance on preparing a 'voice of the child' report. 

The cout found that a financial expert's report was inadmissible as evidence because he was not properly independent or objective, while very little weight could be attributed to the report of an employment expert because he lacked expertise in the area in which he purported to give expert evidence. 

Mr X accepted instructions to provide advice in property valuation despite not being an expert in that field.
