  • In the game of cricket, umpires often fail to detect front foot over-stepping no ball quite often due to faults in human perception which might result in a major change in the course of a match.

    Target Audience: Cricketing Community

  • An umpire who fails to call a no-ball which might result in a completely unfair output after the ball has been bowled.

  • We interviewed an ardent cricket fan, Kishore about this problem and these were his answers.

    1.) How important is the factor of no-ball detection in cricket?

           A single ball can change the course of a match really quick;y especially in ODIs and T20s and if a ball which is a no ball is not called a no-ball, there can be unfair advantage to a team in crucial situation due to human errors of the umpire.

    2.) How frequently has this problem occurred?

           The recently concluded IPL 2019 was criticized heavily for its poor umpiring especially in crunch situations in a match.

    3.) What do you think is the main advantage of solving this problem?

           It will obviously reduce wastage of time and it can also help in curbing match fixing as if the umpire himself is involved in match fixing and has planned on not calling a no ball, he will not be able to do so, plus it eradicates human error completely.


  • The league stage match between Royal Challengers Bangalore and Mumbai Indians in the recently concluded IPL2019 rose to controversy after the umpire failed to call the final ball of the match a no ball, which led to RCB losing the match off the last ball.

    RCB were favorites to win the match as AB de Villiers,their star South African batsman was on the crease and had turned the match in their favour. But,on the last ball  of the match, Shivam Dube was on strike and seven runs were required. Lasith Malinga bowled the last ball and Dube could only take a single, resulting in RCB losing the match. But camera replays showed that the last ball was a no-ball and the RCB camp was disappointed. Had the last ball been called a no-ball, the result might have been different, as it would have meant that RCB needed 5 runs off 1 ball,s which is very much possible in modern cricket.
