The Post Office Horizon IT Inquiry and the importance of Expert Witness training

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.

Admissibility or weight: what is the test for expert evidence?

In an exceptional case, as here, where the expert singularly and spectacularly fails in their duties to the court, expert evidence may be deemed inadmissible and never get to the stage of being tested for weight.
