|The Bill of Rights|
Lawyers will try and persuade you that since GB has no written Constitution it has no Constitution. This is not so, we have 'Constitutional Documents' of which by far the most important are the Magna Carta and the Declaration of Rights 1688, the result of James II demise. The reason these carry more weight is that in both cases the Rule of Law had broken down and the documents represented the conditions under which the rebels would give their Consent to the Rule of Law.
With the illegal Junta in power and her majesty unwilling to dismiss them, the rule of law has certainly been tossed out the window, so maybe it's time that those conditions be announced again.
