On the topic of this thread. I thought that the Law states one thing which is then defined through Case law (I.e. going to Court), so a lot of clarification of the actual legal status of paintball would be defined through court cases, based on what is written in law, the arguments put forward during the court case, and then the judges decision. Which then other judges would use this decision when viewing similar court cases.
Strictly speaking, case law is 'common law' and not have any legislation behind it.
It's based on historic precident and right/wrong.
When you go to a solicitor you would get advised based on their knowledge of case law (hence the importance of solicitors specialising among their colleagues) they then interpret what you tell them of the case and how that would apply to previous cases. Get to court and expect the same results as previous cases, or either side to argue why this case matches or does not match previous cases.
Legislation goes through parliament and sets the criteria
There should only be guilty / not guilty, but for some areas there is the decision to be made on how a situation applies to the legislation
The home office issue guidance to interpreting the law but it's up to a court to decide, police interpret on the day, put a case together, dpp decide if there is a case to answer, the court tries the case
There is little specific legislation for paintball, which leaves interpretation of what applies and doesn't or what would be grey.
No interpretation is fact until it goes to court, but home office guidance is as good as we have, the policeman on the ground making the first decision might not know the specifics of guidance but that would be filled in by the time the dpp get to look at anything
So strictly speaking it's not the court defining legislation in a case, but can consider as part of a case as to how the legislation applies to the case
one situation with that is 12ft Pounds and velocity
Going by 12 ft lbs for a paintball and the legal velocity is over 300fps, but there is case law that set 300fps
You could decide to take a case and argue against the precident that it was set with co2 and not air. But would it be fair to say that it's a good enough argument to disregard the case law?
