 In August 1970, Buller collapsed and died at Edgbaston, Birmingham, during a break for rain, when officiating in a match between Warwickshire and Nottinghamshire.A fearless umpire, he repeatedly called Geoff Griffin for throwing in the exhibition match staged following the early conclusion of the Lord's Test between England and South Africa in 1960, after Frank Lee had called him during the Test itself.This had the effect of ending Griffin's Test career.
