Summary
When DRS shows the ball is only marginally hitting the stumps (less than 50%), the on-field umpire's original decision stands — cricket's most controversial modern rule.
Full Explanation
Umpire's Call is the provision within DRS that preserves the on-field umpire's decision when ball-tracking shows the outcome is marginal. It applies primarily to LBW decisions.
If ball tracking shows less than 50% of the ball hitting the stumps, the on-field decision stands regardless. This means a batsman given not out survives even if the ball was clipping the stumps, while a batsman given out stays out even if only a fraction of the ball was hitting.
The logic behind Umpire's Call is that ball-tracking technology has a margin of error (estimated at around 2.5mm), so marginal decisions shouldn't be overturned.
However, critics argue this creates inconsistency — two identical deliveries can have different outcomes depending solely on what the umpire decided in real time. Many players, commentators, and fans have called for its removal, arguing that if the ball is hitting the stumps at all, it should be out.
Key Points
- •Applies when less than 50% of ball is hitting the stumps
- •On-field umpire's original decision stands in these cases
- •Exists due to the margin of error in ball-tracking technology (~2.5mm)
- •Reviewing team does not lose their review on an Umpire's Call result
- •One of the most debated rules in modern cricket
Notable Controversies
- •Multiple Ashes and India series matches decided by Umpire's Call
- •Virat Kohli and several captains have publicly criticized the rule
- •Creates perceived inconsistency — same ball, different outcomes based on on-field call
- •ICC has discussed removing it but kept it due to technology limitations
