5. It is against the Spirit of the Game:
To dispute an umpire's decision by word, action or gesture
To direct abusive language towards an opponent or umpire
To indulge in cheating or any sharp practice, for instance:
(a) to appeal knowing that the batsman is not out
(b) to advance towards an umpire in an aggressive manner when appealing
(c) to seek to distract an opponent either verbally or by harassment with persistent clapping or unnecessary noise under the guise of enthusiasm and motivation of one's own side.
Think we are missing the point of the phrase 'spirit of the game'.
Spirit of cricket is to be respectful, and play buy the rules. Wagner was both of these.
