One thing that strikes me in all of this is the informality around requests for expert witness statements.
I was really surprised that there was no requirement for him to sign to say that he had read and understood the legal requirements of making a statement on each statement/question answer rather than relying on him remembering an e-mail from some months/years ago.
I think there should also be a statement attached to witness statements on the level of independence from the parties involved in the court proceedings. Many lay people and jurors would assume that "expert witnesses" are independent. But this was obviously not the case and GJ is obviously a biased witness having worked on Horizon for decades.
That requests to give witness statements should come from a designated lawyer on each team in a proper format. It appears that there was a scattergun approach with emails from numerous sources asking questions and requesting statements. I'm unsure that if I received a brief e-mail at work with a question asking me to clarify something that had happened at work that I would automatically regard it as giving a witness statement. The fact that the PO legal team then cut and pasted fairly informal e-mail replies into the evidence seems wrong.
I find Fujitsu's corporate role very odd here - they seemed happy for this guy to dangle without any management input. The whole evidence gathering process seems to have been done on the fly and yet this was potentially a very serious corporate issue
- GJ said earlier that he got no time allowance for having to review the data on these cases - it was fitted around his regular work - why didn't Fujitsu have a dedicated team?
- Some of the requests from the PO legal team seemed ridiculous - like a sudden request from PO lawyers for GJ to review several years worth of data for a court hearing one week later
- What were the Fujitsu legal team doing?
