I'd say that it's not criminal damage. You *might* be able to squeeze a PND out of it somewhere, but you'll be pushing it unless one of the parties kicks off about either the charge or the mess.
And how on earth would you propose that we did that?
Party A has been sick in the back of the taxi, Party B phones the police as Party A is refusing to pay the fouling charge. We rock up, and say what?
There are no limits to how much a person can drink before they're not allowed to be a passenger in a vehicle, and we'd have no power to administer a breath test to see if we could form the opinion that they'd been somehow reckless.
We can't ask people about their medical history, and we can only really ask people if they're ill with a view to requesting an ambo.
Spewing your guts is hardly ever a wilful act, but I think we'd be hard pressed to prove that someone was reckless by doing so.
What do you mean we cant ask people for their medical history?
Everytime I report someone for urinating under the railway byelaws I ask them if they have a pre-existing medical condition which would require them to urinate.
Of course you can ask them...
