Adelaide: The use of Decision Review System (DRS) has been a hot topic of discussion since Indian team's refusal to use it. It once again came in to the limelight on the third day of the first Commonwealth Bank Test between India and Australia here Thursday.

According to Cricket Australia (CA) website, the debate started when off-spinner Nathan Lyon made a vehement appeal for an leg-before-wicket decision against Indian opener Murali Vijay after he was struck on the pad with the final ball of the 22nd over of the innings.
