Chappell felt that India\'s financial might has forced ICC to not implement DRS uniformly.
Melbourne: Former India coach Greg Chappell has strongly advocated the use of the Decision Review System (DRS) in all bilateral Test series, saying technology helps in reducing mistakes.
The issue of absence of DRS hotted up after Mike Hussey and Ed Cowan were controversially dismissed on the opening day of the first Test between India and Australia on Monday.
The BCCI is the only cricket Board which is against the use of DRS in bilateral series.
"Technology is not perfect but the technology has taken the pressure of the umpires. If there's a chance that the really bad ones are overturned and the game is better for it then we should have the technology," Chappell said.
"If you are going to use it then you have got to use it everywhere. I can understand why some of the India batsmen don't want to use the DRS. I think as a batsman you are more likely to get the close decisions to go your way (without DRS).
"If you have the review system, chances are you will be given out more likely than not. We saw today why we probably need the review system," Chappell told Fox Sports News and Views.
Chappell felt that India's financial might has forced ICC (International Cricket Council) to not implement DRS uniformly.
"You have got to think there's politics there in some way, shape or form. The fact that they are so powerful, they (BCCI) pretty much can make the decisions that suit them best.
"Their argument is that it's not conclusive always. There are mistakes made so they would rather go with the umpire's decision," he said.
