Referee's Eye: Millimetres, Umpire's Call and the Limits of Human Decision in Asian Cricket's DRS

I went back and opened my 2026 VAR log again—that 47-slide framework in which all 29 reviews of the Russia World Cup were sorted by decision type, response time and outcome accuracy. The broadcast showed a penalty. The log showed a boundary line—a place where technology and the human eye search for the truth together, yet neither is allowed the final word. Griezmann's VAR penalty in the France-Australia match, the first in World Cup history, was never just a penalty to me. It was proof that technology does not deliver decisions—technology draws the limit of a decision, and then hands the responsibility back to a human being.

That is exactly the place I want to examine in Asian cricket. Because in Asian cricket—India, Pakistan, Sri Lanka, Bangladesh, Afghanistan, and the IPL ecosystem—the DRS (Decision Review System) was never merely a technology. It was a question of power, a question of belief, and ultimately a question of control.

Context: The trial that split Asian cricket

July 2026, R. Premadasa Stadium in Colombo. The DRS entered Test cricket for the first time as a trial in the India-Sri Lanka series. That moment went into history, but what did not go into history is this: Asian cricket administration was not united at the time. The Indian board wavered over DRS for years because its suspicion of the technology's accuracy ran deep. Sri Lanka and Pakistan, by contrast, accepted it relatively early. This division was not merely technical; it was a division of trust—which board was willing to hand power to technology, and which board wanted the human eye to remain the final judge.

The trial era used three main pillars: Hawk-Eye ball-tracking, Hotspot (the heat mark of ball on bat or pad), and Snicko/UltraEdge (sound-based evidence). Of these, ball-tracking is the most controversial, because it is the technology that claims to calculate the ball's future path—a trajectory that never happened but is assumed would have happened. This is where I am personally most interested, because it is a simulation, and my professional suspicion of simulations is lifelong.

In March 2026 I was selected as one of eleven candidates for India's first VAR certification programme. The ISL semi-final, Bengaluru FC versus Mohun Bagan—over 72 hours of tape review of that match I logged 14 marginal offside calls and 3 penalty-area incidents, and produced a 28-page decision audit that FIFA's officiating team later requested for their Asian development archive. That experience pushed every match report of mine into a decision-first structure—because I realised the story of a game is really the story of decisions.

Against this backdrop, the DRS in Asian cricket lives a strange dual life. On one side, in tournaments like the IPL and the Asia Cup, the technology is now the core attraction of the broadcast—when the ball-tracking animation plays on the big stadium screen, the entire gallery holds its breath. On the other side, the on-field umpire is still the human whose finger decides the fate of a decision—until a fielding captain throws a challenge at the third umpire.

Core analysis: Three layers of decision, three layers of doubt

I always divide decisions into three layers—law, application, and match management. Without separating these three, any controversy is only half understood.

First layer: law. The law is clear. In an lbw, the ball must pitch within the line and height of the stumps, and it must be proven that at the moment of impact the ball is travelling towards the stumps. But the first gap enters right here—the word "proof" shifts, in the world of technology, into "model-based prediction." The path of the ball Hawk-Eye never saw is one it estimates, and within that estimate sits a fixed error margin, usually a few millimetres.

Second layer: application. This is where the famous "umpire's call" comes in. Under ICC rules, if ball-tracking shows the ball touching a part of the stumps—but not fully entering them—then the on-field umpire's original decision stands. Many fans think this is a failure of technology. My reading is entirely different—it is not a failure, it is a deliberate design. Because the technology's own error margin has been acknowledged, and when a decision falls inside that margin, the responsibility is handed back to the human. This is a transparent backup for justice, a safeguard against the arrogance of technology.

Third layer: match management. Nobody sees this layer, because it does not appear on camera. When a third umpire watches a complex caught-behind review and decides in 90 seconds, his mind holds not only ball and bat—it holds the state of the match, the pressure of the series, the psychology of the players, even the economic importance of the tournament. I have seen the same kind of marginal decision resolved in two different ways in two different matches—because the context of the match changes, and context influences decisions. Here the line I always recall is this—

In 2026 I learned that certification is not the same as certainty.

An umpire can be trained, can be skilled in using technology, yet a residue of uncertainty remains in every decision. The umpire who admits this uncertainty is a good umpire; the one who denies it errs the most.

Is the ball-tracking animation trustworthy?

The smooth ball-tracking animation we see on broadcast is not the actual camera footage—it is an image generated by a mathematical model built from multiple frames. Two questions matter here. First, the camera frame rate. High-speed cameras usually capture up to 340 frames per second, but even then the exact micro-second of ball hitting pad may not be captured—so the model estimates between two frames. Second, the ball's seam or spin. How much a spinning ball drifts in the air, how much it turns after pitching—the model estimates these, and the greatest error hides in this estimate.

I want to draw a pattern from my 2026 log here. I saw there that the longer the response time, the higher the accuracy of the decision—but after a certain point it began to fall again, because more time means more doubt, and more doubt means hesitation. The same holds for the third umpire in cricket. Decide too fast and you risk error; decide too late and you risk doubt. The ideal window is narrow.

The evidence of sound: the trap of the stump mic

UltraEdge or Snicko is sound-based evidence, and this is where the acoustic sceptic inside me wakes up. Bat, pad, ball, pitch—each has its own sound, and on the field those sounds merge. Stump-mic synchronisation, the latency of audio compression, the roar of the gallery—all of these can reduce the reliability of the evidence. Sound is time-dependent evidence, and with time, a misalignment of the audio channel can cause correct evidence to be labelled as the wrong ball's sound. This is why I believe sound should never be final evidence alone—it is a supporting proof, not a final verdict.

To me the stump mic was never a judge, it was a witness—and a witness's statement always demands cross-examination.

Contrarian angle: The gap between emotion and rule that no one wants to see

Now I come to the place where my writing creates the most discomfort. Cricket fans want "accuracy" in decisions, but they want a particular kind of accuracy—the kind that goes in favour of their team. When a review goes against their team, suddenly the technology becomes suspect, biased, even a conspiracy of purchase. But if the same review goes in favour of the team, that same technology becomes the great triumph of modern cricket. This asymmetry is the biggest falsehood to me, because it tells me fans do not really want the justice of technology—they want the loyalty of technology.

Here a statistical psychology operates that I noticed in my 2026 Silent Whistle Study. When the crowd shouts, the umpire is naturally under pressure; when the crowd is silent—as in the empty stadiums after the pandemic—decisions come differently. But the television viewer does not see this difference, because the broadcast is a staged experience. The roar or silence of the gallery never reaches his ear; he only sees the decision, not the context.

The roar of the crowd enters the microphone, but not the logic of the decision—that is the biggest invisible gap in broadcasting.

Against this backdrop my position on umpire's call is clear. It is not the failure of technology, it is the humility of technology. If the ICC did not acknowledge the error margin of ball-tracking and handed the verdict entirely to the machine, then a simulation error of a few millimetres could change the fate of a World Cup final—with no appeal. The human-preserved margin is therefore not a vessel of error, it is a last fortress of accountability.

And here an economic layer enters, which I often raise. In modern cricket a player's valuation depends on his statistics, and a marginal umpiring decision can directly alter those statistics—a century is cut short if an lbw not-out becomes out, an average falls, a contract figure changes. In other words, umpire's call is not just a decision on the field, it is sometimes a decision about a cricketer's financial future. The bigger this responsibility, the greater the need for a transparent, written, evidence-based process—in which the reasoning behind every marginal verdict is public, not just the verdict.

IPL and ICC: who controls the technology

In Asian cricket there is another layer of DRS that sits outside the game—the layer of commerce. Ball-tracking and other technologies are supplied by specific companies, and these contracts are regulated at board level. The IPL, the richest cricket ecosystem in the world, often influences the ICC's global standard with its technology decisions—because money and viewership tilt to one side. A governance question arises here: when a tournament's commercial value depends on the drama of decisions, is technology used for accuracy, or for entertainment? I do not know the answer to this question, but I know it is important to ask.

The way experiments like the Impact Player rule in the IPL are adopted quickly, while they reach international cricket slowly, shows that the pace of technology in Asian cricket is not at all equal. Franchise cricket is the laboratory, and national-team cricket is the beneficiary of those experiments. This inequality has a price—players play by one rule in the IPL and another in international matches. And every rule change means fresh pressure to learn, fresh possibility of error.

Takeaway: The bigger question is not about technology

I want to end with a question, not a verdict. As Asian cricket enters the next decade, the DRS will become more accurate, ball-tracking frame rates will rise, sound analysis will become finer—this is almost certain. But will this improvement in technology increase the justice of decisions, or only the speed of decisions? Is a faster wrong decision better than a slower right one? And the biggest question—are we prepared for a future where technology delivers the decision, but no one takes the responsibility?

I opened my 2026 VAR log again—what the broadcast missed was not the failure of technology, it was human discomfort. In cricket the same log is being written in every review, in every umpire's call.

My suggestion is simple, but uncomfortable. After every controversial decision, the ICC should publish not only the final verdict but the reasoning behind it—which frame, which margin, which part of which law the decision stands on. Because a cricket fan will not trust technology unless he can see the reasoning. And without the reasoning, even a technology accurate to a thousand millimetres will tell a story of conspiracy instead of a story of a decision.
