If the defence shows/mentions (part) of documentary evidence, can the prosecution then demand all of it? If a defence lawyer mentions a document or shows a document to: - the prosecution, before a case goes ahead, to show there is no case - the court, during a hearing How much (if at all) does that result in the prosecution being able to access (more of) that document? Specifically: 1. Bank statement: - The defence wants to show payments were made. - Before any trial they tell the prosecution they have this evidence or actually show them a statement for the relevant period. - Or they bring the relevant statement to court Would any of these scenarios result in the prosecution being able to get access to bank statements from years before for the same account? 2. Facebook conversation: - Part of a Facebook conversation (between the defendant and another) is beneficial - Before trial they tell the prosecution they have this or show them the section - Or they show the section at court - Can the prosecution demand to see the whole conversation? and - What about if the defence mentions/shows the whole of one convo? Can the prosecution demand to see all the person's Facebook conversations (with everybody)? 3. SMS - ditto: - rely on one or two SMS between the defendant and another = demand all SMS between them? - rely on SMS exchanges between the defendant and one other = see all the person's SMS, to/from everybody?
