I really don't know to much about it apart from when my old PPL school getting done for operating an aircraft without a CofA.
It could very well be a PPruner, there are loads of Police/legal type PPL's about in scotland.
I presume some poor sod will get given the task of gathering all the relevant details together. Then in conjuction with the CAA legal types work out which pieces of legislation are thought to be of an issue. Then a report will get sent to the proc fiscal office who will decided what is to be done next.
Then if it is getting taken any further it will be the Proc Fiscal or one of his/her deputies who then take the case further.
If it does get taken futher it will be a major pain in the arse for all concerned and could very well bugger peoples holidays and roster patterns up.
But then again we could get a bash together and give the Grassmarket a good seeing to.
