England have sought clarification from the match referee over the use of the Decision Review System (DRS) by the third umpire after the dismissal of Mark Stoneman on the first day of the third Test in Perth.
The England captain, Joe Root, and coach, Trevor Bayliss, went to see the match referee, Richie Richardson, after play at the end of the first day in an attempt to understand the process by which Aleem Dar gave Stoneman out.
Dar overruled the not-out decision by the on-field umpire Marais Erasmus on evidence the England camp felt was far from conclusive. While footage later emerged which seemed to suggest Dar was correct, England wanted to make the point that the umpires had not had such footage when the decision was made.
Stoneman was given out caught behind after Dar adjudged the ball had brushed the glove while it was still on his bat on its way through to the keeper.
While the England camp are disputing that they made a complaint, it is clear they were unimpressed by the speed of Dar's decision and wanted to know what evidence he had for making it. Root was understood to be particularly angry, and was seen thumping the dressing room door in frustration when Stoneman was given out.
England's wider issue is with the lack of standardisation with DRS around the world. The equipment used - and therefore the process - is different depending on the capabilities of the host broadcaster, with England hoping the ICC eventually insists on standardisation.
