New Delhi:An umpire decision review system will be put on trial during India's three-Test series against Sri Lanka, which would entitle a player to request the on-field match officials to reconsider their decision.
BCCI secretary Niranjan Shah said the cricket board has agreed to the trial of the system in the Test series starting July 23.
Under the proposal, a player may request the review of any decision taken by the on-field umpires concerning every dismissal with the exception of 'Timed Out'.
The review-seeking player would have to make a 'T' sign with both forearms at head height.
For reviews concerning potential dismissals, he should then indicate 'Out' by raising his finger above his head or indicate 'Not Out' by crossing his hands in a horizontal position side to side in front and above his waist three times.
"Where the decision is a reversal of the on-field umpire's previous call, he should make the 'revoke last signal' indication immediately prior to the above," the BCCI said in a statement.
Each team will be allowed three unsuccessful review requests per innings. If a review results in the umpire reversing his original decision, then the request has been successful and does not count towards the innings limit. If the umpire's decision is unchanged, the review is unsuccessful. After three unsuccessful requests by one team, no further review requests will be allowed by that team during the current innings.
If following review, an umpire upholds the decision of 'Out' but for a different mode of dismissal from that for which the original decision was given, than the request will still be regarded as unsuccessful.
It also allows the TV umpire use of slow motion, super slow motion and ultra motion replays from all available cameras, sound from the stump microphones with the replays at normal speed and slow motion and Hawkeye for ball tracking purposes only, but not for predicting the potential future trajectory of the ball.
