Interesting. My country (the United Kingdom) doesn't even have a constitution, at least not a single written document. It's what we say is 'unwritten' or 'uncodified', and is based upon statutes, court decisions, treaties, the thinking of learned legal authorities (Coke, for example - no, not the soft drink, I mean Edward Coke, the eminent 17th Century jurist).

So the British 'constitution', such as it is, is a very different creature from the American one you would have; it's an 'organic' one, which grows, adapts, and changes with the times, whilst remaining anchored in ancient and cherished principles of individual freedom and liberty ...
