Umpire's decision is final??

How sad to see cricket going the way of football. The present shenanigans between India and Australia haven't come out of the blue, but are the end result of what's been brewing for years. It is ironic that the Australians, who pretty well invented "sledging" are now complaining about it, but more important in my opinion is the way the essential spirit of the game has been cast aside in the pursuit of victory at all costs - and this isn't just a matter of Australia and India. Cricket is supposed to be essentially a self-regulated game. Law 27 makes it quite clear that the umpire is not there to decide for himself whether or not a batsman is out, but to rule on dismissals only where the sides cannot agree, or are unsure. If the batsman knows he is out therefore, he should walk. If he does not, and the fielding side think he is, they can, by appealing, ask the umpire to rule on the matter. It equally therefore follows that the umpire's decision is to be accepted by both sides. The current situation, where batsmen, clearly out, do not walk, and fielding sides make aggressive and hysterical appeals on the flimsiest of grounds, goes against the very basis of the game. By bowing to pressure to change umpires, the ICC have clearly demonstrated that, like football, money matters more than the game - a sad, sad state of affairs.
