I know when the scheme started that this came up and they said that initially stud dog owners didn't have to have ID, as not in the control of the ABS breeder, but that eventually all breeding stock used by AB's must have Permanent ID.
I'd be asking the stud dog owner why his dog wasn't hip scored, so the ID wouldn't' be an issue. As I said hip scoring really ought to be across the board for all breeds, and in my opinion eye tested to check for emerging problems before they become a widespread issue..
