After experimenting with the technological aid for umpires while making decisions, the ICC formally launched the Decision Review System (DRS) in November 2009 for Test matches. The objective was to offer a near-conclusive evidence to the TV umpires.
Despite mixed reactions from Test-playing countries, the ICC announced in October that they will implement the DRS in the World Cup. However, the pullout by suppliers of Hot Spot, an infrared device regarded as the most reliable tech aid, gave a jolt to the exercise.
As a result, without the Hot Spot, the Hawk-Eye, which tracks the path of the ball, and the Snicko, which aides in determining the contact between the bat and the ball in case of a close decision, the DRS has become a joke.
When it comes to bat-pad lbw and caught behind decisions in particular, the DRS could end up as a waste of time, as was the case during Sri Lanka's 210-run mauling of Canada on Sunday.
It would have been better for the ICC to have dropped the DRS for the World Cup, instead of implementing an inconclusive system.
"You need to make sure fair decisions are being made, and we need to help the umpires, especially because in the conditions it's not easy for them to make correct decisions all the time," Sri Lanka vice-captain Mahela Jayawardene said after the match.
