The EA is indeed not a charter that allows people to set their own rules, but it does set standards against which the conduct of businesses can be considered, and
does require them to make reasonable adjustments. Providing parking spaces for disabled people, that are only to be used by those who are disabled, and are closer to the entrance of a business than regular spaces, is a very well established adjustment.
Whilst blue badges have no automatic 'power' on private land, requiring their display is a fairly straightforward way of ensuring that those who are not disabled do not misuse disabled spaces. But, I would argue that someone who is entitled to a reasonable adjustment (such as being allowed to park in a disabled space) does not lose that entitlement simply by virtue of their blue badge falling off the dashboard. Of course, at the point of issuing the charge UKPC are unaware of the motorist's disability due to the (alleged) lack of visible blue badge, but it is now being brought to their attention.
I agree that an argument of commercial justification wouldn't be resolved without a court visit. Although at present I'm struggling to see any arguments that would be - getting the landowner to intervene remains the best option in that regard.
Where did you find the BB? Clearly, if on a seat and visible this is something you should say.
Agreed - we've seen plenty of cases where badges (and indeed pay & display tickets) have been readily visible to anyone giving more than a cursory glance.
As regards Redx's comment
Whilst Redx and I might never have been seen in the same room together we are definitely not the same person
