In cricket, LBW stands for "leg before wicket" and means a batter is out if they fail to make contact with the ball and the delivery is adjudged to be crashing into the stumps. Umpires call comes into play when the Decision Review System (DRS) is used for an LBW. The third umpire would then use the ball tracking technology available to determine whether the batter was out LBW. If the technology proves inconclusive due to the tightness of the decision, the result would be umpires call. The umpires call simply means that the on-field umpire is given the benefit of the doubt for their original verdict on an LBW that was challenged and reviewed. This is after the third umpire concludes that the original decision was too marginal to be adjudicated otherwise after the review. The umpires call has drawn the ire of many cricketers, former and current, and a few retired officials. They argue that it complicates the situation, thus calling for simplicity of the rules. The umpires call rule makes sense because the ball tracking technology predicts the path of the ball hitting the stumps after it has made an impact. What we see on the screen is one of the several predictive paths and not the only one. For this reason, the umpires call rule is applied to account for the margin of error of the ball tracking procedure.
