In Test cricket, umpire’s call can be used to decide an outcome as part of the wider Decision Review System (DRS).
Umpire’s call refers to the original decision made by an on-field official and is used in scenarios where no conclusive outcome is reached by technology.
One example would be a potential leg before wicket (lbw) call and whether the ball was on track to hit the stumps or not.
If the umpire gave the decision as out and the technology could not definitively prove or disprove that, the decision would remain out.
If the on-field officials opted not to give the decision as out and the review from the technology was inconclusive, the decision would remain not out.
Umpire’s call is also used to help determine lbw decisions where the impact made with the batter is more than 300cm away from the stumps.
