voice - I think the OP went off piste on his own account. It is the most awful feeling when a witness does that as there is nothing you can do.
Re the coaching, you can't really do that as:
- The evidence has to be the witnesses own. Quite often, I've had managers say to me "tell me what you need me to say" when taking statements for the employment tribunal and I've had to say that they need to just tell me the truth, in their own words.
- Particularly in criminal cases, if a witness says they are guilty and/or are going to lie, then you need to withdraw from acting. So, OP's lawyers and Barry Roux will have simply asked OP what happened (never ask the accused if they are guilty as, if they say they are, but plan to plead not guilty, you would need to withdraw immediately!). They will then advise him on the basis of that.
What you can do, is test the witness when preparing g for the hearing by saying that you are playing devil's advocate and what would he say if asked by the other side....? That is allowed and is fine.
In all honesty, no offence to the general public as I would be the same, there is no point in coaching, as (under stress in the witness box) a witness will just fall apart as they won't be as used to the whole process as the lawyer questioning them
People telling the truth can have slips etc but as they have a pretty clear narrative, they tend to get back on track fairly quickly and stick to the same themes
One thing I do think is that when I am preparing witnesses, I will explain to them what we are trying to achieve and how their evidence fits in. So, I would explain that we are defending a claim of unfair dismissal. The legal basis is x and their statement is of assistance as it demonstrates y. I will explain exactly what tests the judge will be applying. I will keep explaining until I am sure the witness understands. It is a horrible experience giving evidence even at a Tribunal. Really stressful and it's important that the witness knows what we are trying to do (based on their evidence not asking them to change it to fit in) so it's important that they have the basic outline to guide them and to self-refer to when being cross examined.
I don't get the feeling that OP's lawyers have done that enough. I don't think he really, truly understood his defences to each charge inside out and how they all inter-related. Coupled with the fact that he actually isn't telling the whole truth so can't keep up with Gerrie Nel, this has been the result
