Most people understand "a constitution" to mean something written down that you can point to, that has the force of <something> behind it, that cannot be trivially elided by a government.

None of these are true of the UK "constitution", whether it is one document or 5000 precedents.

Any document written in a spoken human language will be open to interpretation - there's no getting away from that, regardless of the language, culture or country the document comes from. I still consider that a step up from the bullshit assemblage of "constitutional law" that claimed to be "the UK constitution".
