DUBAI - The International Cricket Council (ICC) Thursday decided to reduce the number of appeals in umpire decision review system trial from three to two for the West Indies’ home series against England.

The decision was taken after the receiving initial feedback from players and match officials and if proved successful, will be used in Australia’s tour to South Africa.

Once both the series are over, a full appraisal of the trial will be undertaken and then it will be decided at ICC Cricket Committee meeting in May, whether to continue with the review system or discard it.

‘The umpire decision review system trial has so far received mostly positive feedback from players and officials but we want to get it right before we consider applying it to international cricket on a permanent basis,’ ICC Chief Executive Haroon Lorgat said in a statement.

‘That is why we have made this refinement to it. It has become clear during the trial so far that three unsuccessful reviews per innings is too many as there is potential there for frivolous or unnecessary reviews to be made by one side or the other.

‘This is all part of the trial process. We are testing different playing conditions so that we can find the best one and give the trial every chance of succeeding. We listen to feedback and we have been hearing that two is a preferred option.’

With this change, the system will see the fielding and batting side allowed two unsuccessful appeals to the umpire per innings to change a decision if it is perceived to have been incorrect.

The rest of the playing conditions for this trial remain unchanged. The appeals can be made only by the batsman in receipt of the umpire’s original decision or the captain of the fielding side, in both cases by the player making a ‘T’ sign with both forearms at shoulder height.

The on-field umpire will consult with the third umpire, who will review available television coverage of the incident before relaying fact-based information back to his colleague.

The on-field umpire will then deliver his decision either by raising his finger to indicate ‘out’ or by crossing his hands in a horizontal position side to side in front and above his waist three times - as per a ’safe’ decision by an official in baseball.

If it is different to his original decision, the umpire will touch both shoulders, each with the opposition hand, to revoke the previous signal and then make a fresh signal as per the revised decision.
