Kumar Sangakkara, in his column in the Telegraph, talks about the positives of the umpire review system, which is under trial in the Sri Lanka-India Test series.

The bottom line in the current Sri Lanka-India Test series that I am playing in is that obvious mistakes have been corrected and the quality of decision-making has been high.

Concerns that technology would undermine the role of the on-field umpire have proved misplaced. Player referrals are a radical departure from the game's traditions, but we have seen both teams conduct themselves responsibly on the field when requesting reviews.

Only where obvious mistakes have been made, like whether the ball pitched outside leg or in-line, or whether there was an inside edge on to pad, will the third umpire recommend that the on-field umpire changes his decision.
