BCCI is a champion at doing such things--fighting bitterly over political nothings and brushing the real issues under the rug.
If the committee didn't find Chappell's ways of obtaining evidence to substantiate his claims trustworthy, it should've used better ones to counter his claims. Speaking to both separately and then announcing the verdict in less than a day is hardly a "comprehensive" review of what has happened. They should have spoken to both simultaneously if they really felt it was a case of miscommunication, like Chappell made Ganguly speak with Laxman before him. It is a shame to the former cricketers like Gavaskar and Shastri. But I really don't blame them--I guess they didn't have a chance to do anything so long as Mahendra and Dalmiya were also on the committee.
When will BCCI have office bearers that actually know cricket? It is the same state as our government, politicians managing the nation without an ounce of managerial capability. BCCI is a bunch of businessmen managing Indian cricket without themselves having any knowledge of the game.
