I thought that this was 'policed by complaint' but we've had reason lately to ask a couple of questions of our local authority and its obviously rung a few bells with them, to the extent that they've written to a colleague that 'if it comes to their attention that blah..blah...blah, they will take action'.It's not a question of US taking the risk, it's the gaffers who have us in their pubs - or who may not if they decide they don't want to get a PEL.
Is there any onus, incidentally, on the organiser, ie the person whose name is in the sessions listings for contact. And is there an insurance issue - if something was going on without PEL would public liability insurance be invalidated?
