By the way, if it fell to running a technical defence, the lawyers would be trying to conjure some way of applying the words 'proceedings in Parliament' in the Bill of Rights to a whole lot of false accounts of expenses, mortgages etc. It sounds like a typical first 'solicitor's point' rather than one seriously proposed as a runnable argument by senior counsel.It's the kind of thought that would come to counsel's mind when counsel is first asked in general terms what his first thoughts are, off the top of his head, and before he's sent his junior or pupils off to find the law (such trade secrets,not for public knowledge !) or studied the papers and law in depth.Still, the golden rule is to keep evidence out not in, the less in the better,and that would get rid of a great deal, at a stroke, and could leave the Crown with not much of a case, if any.So you'd be looking for any points like that, in preliminary thoughts, though they prove useless after checking.
