Melbourne Cricket Ground, March 19, 2026. The World Cup quarter-final, Bangladesh against India. A delivery in the fortieth over. Mustafizur Rahman's slower ball, Rohit Sharma playing his shot too early, the ball brushing the top edge of the bat and climbing into the sky, and a fielder inside the boundary taking the catch. The whole ground erupted with Bangladeshi supporters. A moment later, the umpire raised his arm and signalled a no-ball. The catch was taken, yet it was not out. Rohit was on 90; he would end unbeaten on 137, India would win the match by 109 runs, and Bangladesh's World Cup run would end there.
From that night onward, one sentence kept circulating in Bangladeshi cricket talk: the no-ball was wrong. But when I opened the law book, the story looked far more complicated. That delivery was a full toss that passed above the batsman's waist. Under the ICC playing conditions, any full toss above waist height — slower ball or not — is a no-ball. In other words, the umpire's signal was lawful. Fourteen frames can overturn a decade of habit, and that night it did.
This is the biggest lesson in modern cricket. While watching, we judge with emotion; the umpire judges with the text of the law. It is in the gap between these two languages that controversy is born. To understand the issue, one has to enter the history of the Decision Review System, the DRS. It was first introduced in Test cricket in 2026, and in ODIs and T20Is in 2026. The core idea is simple — a player who doubts a decision may send it to the television umpire for review. But a word slips in here, the most debated word in Asian cricket: umpire's call.
What is umpire's call? Put simply, if ball-tracking technology shows the ball would have hit the stumps but not with certainty, only very close, then the on-field umpire's decision stands. In other words, if the technology hesitates between yes and no, the human's ruling is final. For LBW, the rule is this: if more than 50 percent of the ball enters the projected zone of contact with the stumps, it is out. If it is less, the decision returns to the on-field umpire. That 50 percent line has been the most cursed feature of Asian cricket.
It must not be forgotten that DRS is not universal. Many bilateral series, especially tours involving smaller member nations, are played without DRS. The same law, the same game, yet two different systems of justice. This inequality creates the biggest question about the standard of decision-making in Asian cricket.
From my twenty years of watching matches, I can say DRS is not a truth machine; it is a probability calculation. Only by entering that calculation can one understand why the same event can produce two different outcomes in two matches. First, the construction of ball-tracking. From the moment a delivery is released until it reaches the stumps, the entire path is captured by cameras, frame by frame. When a ball travels at roughly 140 kilometres per hour, it jumps several centimetres from one frame to the next. The software fills that gap with a mathematical estimate. Every prediction therefore carries a margin of error. I have often watched slow-motion replays and noticed that in two different frame-steps of the same ball, the point of impact with the stumps shifts by a few millimetres. Those few millimetres sometimes decide a match. Until the replay tests it, every law is only a hypothesis.
Second, the interaction between Law 36 and the DRS protocol. According to the text of the law, three conditions must be met for LBW — the pitch of the ball, the impact, and the strike on the stumps. Technology examines all three conditions, but it does not take on the role of judge. Because technology only shows a probable path; whether the ball would have hit the stumps is a final question that is never one hundred percent certain. That is where umpire's call is born.
Third, the pitches of the Asian subcontinent. On the slow, low, turning wickets of India, Bangladesh, Sri Lanka or Pakistan, the ball bounces less and spins more. Ball-tracking estimates therefore become more uncertain. I have noticed that on spinning tracks, DRS predictions often get stuck in the umpire's call zone, whereas on fast, bouncy wickets the decisions are much clearer. This means technology itself depends on the nature of the pitch. Asian cricket therefore sees more umpire's calls than Europe or Australia.
Fourth, the umpire's position and angle of vision. The on-field umpire sees the pitch of the ball, its height and line from a fixed angle, in fractions of a second. Their decision is therefore human. But the umpire's call rule gives this human decision equal or greater weight than technology. This is the curious part: the very technology we treat as a symbol of precision, when it expresses doubt, returns to the human.
Fifth, the rule on retaining reviews. Under the current ICC protocol, if the result of a review is umpire's call, the reviewing team does not lose its review. This subtle rule greatly reduces the risk of reviewing, and at the same time increases the number of reviews. The pace of the match, the psychology of the players, and the patience of the spectators all depend on this single sentence.
Sixth, the front-foot no-ball. Since 2026, the ICC has empowered television umpires to check front-foot no-balls, and after 2026 this process became more institutionalised. In the space of a single frame, the position of the foot changes, and that one frame determines the value of a wicket. In 2026 the ICC abolished the soft signal for catches — because in the face of clear evidence, there was no longer room for assumption. Referee's Eye | Scenario: opening a deep rules breakdown.
Now to the uncomfortable question that very few commentators raise. We generally assume that when technology arrives, controversy will decrease. But in Bangladesh and Asian cricket, the opposite has happened. Since DRS arrived, controversy has not diminished; it has become more subtle and more emotional. Previously the argument was whether the umpire had erred; now the argument is whether the technology has erred. And proving that technology erred is difficult, so the resentment accumulates more deeply.
My second disagreement is sharper still. We curse umpire's call as a lottery, but it is really a safety ring — an admission that technology too has limits. A cricket society that treats ball-tracking predictions as the word of God is actually misunderstanding science. Ball-tracking is not a prophetic truth; it is a probability model with its own margin of error. The moment we accept this, the emotional pressure will ease.
Third, the very incident we are so angry about often does not match the text of the law. The 2026 no-ball is the example. Public opinion said the decision was wrong, but the text of the law said the decision was right. That means our anger is not against the law, but against our own misunderstanding. This is where I find the greatest gap: spectators judge with emotion, umpires with text. No one translates between these two languages.
Will the limits of umpire's call change in the future? Probably. Cricket's technology is constantly being refined, and the margin of error in ball-tracking is shrinking. Perhaps one day that 50 percent line will pass into the pages of history. But before that, we must change one habit. On every controversial decision, the question should be — what does the law say? Then — what does the replay show? And finally — what is the margin of error in the technology? Only by combining the answers to these three questions should a verdict be reached, and otherwise not. Because my twenty years of experience tell me that controversy does not accumulate over truth; it accumulates over ignorance.
