Chappell's statement came after Australian batsman Mike Hussey and Test debutant Ed Cowan were incorrectly adjudged caught behind on the opening day of the first Test against India.

Both players could not refer their dismissals to the third umpire because India has refused to use DRS technology.

Cowan was subsequently denied a century, and Hussey is already under fire over his poor run.

Chappell echoed Cowan's view that the use of DRS should be made mandatory.

"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," said Chappell.
