Hi stan - sorry you got screwed over this
various points of various importance arise
NJ does / did alot of criminal procedure and so his analysis would be correct.
so pay the fine and put it down to experience UNLESS you are gonna lose your carriage licence ( or whatever ) in which case you will have to fight it
haha o god how I laughed when I read the two nice police officers had said you would hear nothing more ( so you wouldnt garner defence evidence in your favour ) and then you DID! Evidence gone - poof ! you get screwed. [been there. ]
The notice or lack of it is a non starter. (IMO)
Do you say to the punters " no drinking as usual boys!" or something else ? Or do you rely on the notice and nothing else in which case I rather think you are screwed. Actually I dont think the notice may be sufficient alone.
and no I am not sure if arresting/ stopping two lads with drink on them proves that it was carried on a bus - especially if all that there is - is their say so. That is the two police can prove the two lads had drink on them but that does not prove they pre-bought it and took it on the bus.
also go onto BAILII and put in "allow alcohol"
and hey you get scottish cases ! such as this

Feeney v the Fiskie [2014] ScotHC HCJAC_84
which makes me think you might have a defence to be honest
so it now depends on
does you livelihood depend on it
and how much will it cost to defend ?
If your livelihood doesnt depend on it
I would suck your belly button in, pay the fine and put it down to experience
we all have to learn the hard way - sozza
