Case law
Case law
Remember the law is not always straight forward and english law is often qualified by case law. Take reasonable excuse, you have a multi tool that locks, it is strictly speaking illegal to possess (locking blade), circumstances could allow that you have to allow the courts to make the judgement (you get nicked) and it will then become case law (you are acquitted or found guilty according to the circumstances).Like all English law nothing is simple from memory there are at least 5 or six different sets of legislation going back to 1953, up to the present day.
Some case law judgements
"Obviously there is force in the view that Parliament really should not have brought what used to be called pen knives which have devices for locking the blades for reasons of safety, within the penal provisions of the Statute. A carrier of such should, it can be said, not have been required by Parliament to provide a "good reason" for having the article with him. However, it seems to us that "folding" in its ordinary meaning, means "foldable" at all times without the intervention of some further process, namely the pressing of a button or release of a catch, and that if any form of "lock knives" are to be brought outside the legislation, that will need clearer definition..."
"Accordingly we would dismiss the appeal.
Application for leave to appeal to the House of Lords refused, but point of general public importance certified as follows:
'That the article 'a folding pocket knife' as mentioned in section 139(2) Criminal Justice Act 1988 as being an exemption subject to subsection (3) to the offence made by section 139(1) means a knife that has a blade that folds, whether or not it (the blade) is capable of being opened and locked into an open position and equally capable of being folded once the mechanism had been operated to unlock the blade."
So that final judgement, despite maintaining the offence of possession of a locking folding pocketknife, seemed to suggest that the unquestioned possession of such a knife should not be an offence.
