The International Cricket Council (ICC) has revealed that the use of the Decision Review System (DRS) has increased the percentage of correct decisions being made during the Cricket World Cup and confirmed that they have not changed the ruling on decisions made when a batsman is hit on the pad more than 2.5 metres from the stumps.
The figure of correct decisions made has risen from 90.18 percent to 97.82 percent following the introduction of the system for the tournament.
"It is a fact that the number of decisions in this event is way above the normal average for ODIs," David Richardson, ICC General Manager - Cricket, said.
"This is because of the type of wickets that prevail in the sub-continent where the bounce is often lower and where there is a greater amount of turn. What it is demonstrating clearly is that the DRS is helping umpires who are maintaining consistently high levels of performance."
While the ruling over leg-before appeals has not changed, Richardson clarified that the umpires had unanimously agreed on a consistent interpretation, agreed as follows:
When a batsman is originally given NOT OUT, graphics are displayed when the distance from pitching to impact is less than 40cm and the distance from impact to stumps is greater than 2.5m.
These are the guidelines which have been given to the umpires.
(a) If both the 40cm and 2.5m graphics appear for the same delivery, the batsman will definitely remain NOT OUT.
If the “MORE THAN 2.5m” graphic appears without the 40cm, the third umpire will be informed by Hawk-Eye of the exact distance of impact from the stumps.
(b) If this distance is greater than 3.5m, the batsman will definitely remain NOT OUT.
(c) If this distance is greater than 2.5m and not more than 3.5m, the third umpire is to advise the on-field umpire to overturn a NOT OUT decision when some part of the ball (as presented by Hawk-Eye) is hitting the middle stump AND the whole of the ball is hitting the stumps below the bottom of the bails.
(d) If the ball is not hitting within the parameters outlined in (c) above, the batsman will remain NOT OUT.
For (c) and (d) above, the third umpire will make the judgment by viewing Hawk-Eye from above and side-on, and advise to the on field umpire the exact distance, view from side on and the on field umpire will actually make his decision based on this additional information provided by the third umpire, as set out above.
Richardson added: "This is not a change in rules as some people have suggested but a broad guideline which we hope will bring a consistency to the decision making."
Controversy over the system arose following India's Group B tie with England, when Ian Bell was struck in front and following a review, was given not out despite Hawk-Eye predicting the ball to hit the stumps.
As he was more than 2.5 metres away from the stumps, and the ball was not predicted to hit middle stump, he was given not out.
