Re the comment about Barnes resuming his legal career, there are many people in the UK and particularly in USA who qualify as lawyers but never do a day's legal work. They still call themselves "lawyers". Our Parliamanet is full of them. I don't know what legal practice Barnes had before he became a full time ref but due to the age at which he became a ref I would suspect not much.
as I said in a previous post, I think a lot of barnes' elvation to the rank of "top referre" came from his acquisition of celbrity stus on TV rahter than his quaity as a ref. Never liked his referreeing or his style of doing it.
