If someone were to say ‘it’s not tennis’, or ‘not football’ of shabby behaviour in any walk of life, he or she would not be understood. If they said ‘it’s not cricket’, they probably would be (though less reliably than a century ago). Is there some special spirit of cricket? The laws of cricket, like the laws of the land, aim at a sort of justice or balancing between different factions. The purpose behind cricket’s laws, and behind changes in them, is often to calibrate the balance in the game between batsmen and bowlers, between attack and defence, between safety and risk. Cricketing lawmakers are interested in the overall appeal of the game to players and spectators alike. Mike Brearley alternates between issues and examples within the game – from ‘Mankading’ and the ‘Sandpaper’ affair to sledging, mental disintegration and racism – as well as broader issues such as the spirit and letter of the law.
