Yes this...Star Hobson's case for example. FS provided information on the stand that she had never disclosed before nor was it in the court bundles. Both the prosecution and SB lawyer accused her of being in contempt of court? (I think that's the term they used).My legal experience wasn’t in criminal cases (it was in family law) BUT I’m pretty sure the defence will know exactly what evidence the prosecution has in order to form their defence.
In the Vardy v Rooney case it was Vardy's own team who swapped their Court evidence bundle with Rooney's team (evidence bundles were always sent on the same day so that neither side had the chance to change/remove anything) which accidentally included all Vardy's WhatsApp messages to her assistant incriminating themselves.
There won’t be any bombshell dropping because both parties know what each other will be bringing before the Judge.
