Then there was arthur fagg, former england test player, and then test umpire,who refused to take the field in 1973 after the west indies had disputed one of his decisions.Umpiring is a thankless task, if we want quality umpires they have to be paid well and they must be allowed to have the final decision, any questioning of decisions should be done in private and afterwards, umpires performances should be monitored and checked periodically and they should be assessed as to whether they are good enough to continue as test umpires but this should be done away from the media            in private and with decorum and dignity.
