The Limits of Review Protocol in Asian Cricket: Three Cameras, One Verdict

The diameter of a cricket ball is about seven and a half centimetres. Half of that — roughly 3.6 centimetres — is the invisible line on which Asia's most disputed decisions are born. When ball-tracking calculates that the ball is clipping the edge of the stump by just under half a ball's width, a phrase appears on the big screen — Umpire's Call. The on-field umpire's decision survives, the review fails, and the crowd's shoulders drop. Yet had that same ball gone a few millimetres further in, the decision would have flipped and the crowd would have applauded.

I have seen this kind of match from three angles — the angle of ball-tracking, the angle of UltraEdge, and the angle of the on-field umpire. What years of watching matches taught me is this: much of the argument about reviews in Asian cricket is not really about the umpire's eye or the player's fault — it is a story of protocol, calibration and the limits of evidence. The truth is still caught in the replay, but the replay itself is not a perfect witness.

Context: How Asian Cricket Learned to Live With Reviews

Review technology was born in Asia, just as the deepest suspicion of it lived in Asia. In July 2026, in the Sri Lanka versus India series, a trial system of ball-tracking and Snickometer-based reviews was used in Test cricket for the first time. Yet the technology's loudest critic was also an Asian board — India. For years India rejected the system, fearing that technology would intrude on the batsman's freedom and that on spin-friendly pitches it would break the rhythm of the game.

The clearest proof of that rejection is the 2026 One-Day World Cup. Not a single decision could be reviewed in that tournament, hosted on Indian, Sri Lankan and Bangladeshi soil, because the host board would not consent to the technology. This is the moment in the modern history of Asian cricket when it became clear that the review is not merely a technical question — it is a question of power and politics. Which technology enters the field, whose money installs it, and who explains it — these are decided by boards, not by the ICC.

When India finally accepted reviews at home around 2026, the technology had already become an inseparable part of cricket's decision-management. The ICC's playing conditions now state clearly which decisions can be reviewed, who may request a review, and the cost of a failed review. Asia Cup, bilateral series, World Cup — the protocol is the same everywhere now.

The financial foundation of this technology also lies in Asia. In 2026, the Indian Premier League's broadcast rights sold for 48,390 crore rupees, the highest of any cricket league in history. In the same cycle, the largest share of the ICC's revenue — roughly 38.5 percent — goes to the Indian board. The board that pays the most for the technology is the board that decides the logic on which that technology rules. This is the invisible layer of the review debate, the one the camera never captures.

Core Analysis: Three Angles, One Truth

The first angle, ball-tracking. Hawk-Eye's cameras capture many frames per second and trace the ball's speed and trajectory. The software tracks the ball until it pitches, then projects it onward to the stumps. But here is the first gap. If the ball hits the edge of the pitch before bouncing, its spin and trajectory change, and the software estimates that change — that is calculation, not observation. That calculation has a tolerance, and the name of that tolerance is Umpire's Call.

My clear realisation — ball-tracking is not a photograph of truth; ball-tracking is a photograph of probability. The ball that travels toward the stumps on screen was never actually there on the field; it is a future drawn by a model. And how fair is it to overturn a present seen by a human eye on the basis of a future drawn by a model — that is the real question of Asian cricket.

The second angle, UltraEdge. This technology hears the sound of the ball on pad and the sound of the edge, and draws a spike on the screen. The problem is that if the bat strikes the pad, the two sounds arrive at almost the same moment. The umpire must then judge whether the first peak of the spike belongs to the bat or the pad. That judgement is not of sound but of time. If the frame rate is low, the two spikes cannot be separated. Here I have seen that many controversies are not about sound but about frame rate.

My 2026 experience is useful here. When I moved from studs to whistle and from whistle to microphone in 2026, I learned to write every explanation in two layers — first what the player felt, then what Law 12 actually said. That two-layer frame taught me that an UltraEdge spike only says 'there was a sound'; it does not say 'who made the sound'.

The third angle, the on-field umpire's eye. This is the most underrated angle. The camera sits at a height; the umpire stands on the ground. How much the ball will bend in after hitting the grass, the umpire judges against his own knee. That judgement is not perfect, but it is taken from the field's reality. When a review overturns it, the camera does not actually prove the umpire wrong — it replaces one view of the field with another.

Placing the three angles together clarifies a structure I divide into three separate questions. First, was the process right? That is, did the umpire stand in the right place and decide at the right time? Second, was the protocol right? That is, were the review rules, the soft signal and the standard of evidence correctly followed? Third, was the decision right? The answers to these three questions do not always agree. A wrong decision can emerge from a correct process, and a correct decision can be born from a wrong protocol.

Understanding this distinction matters, because the crowd usually asks only the third question — was the decision right. Yet to honestly evaluate a review system you need the first two answers. A system that follows process and protocol can be trusted even when it produces a wrong decision. A system that produces the 'right' result without following process cannot be trusted.

I keep in mind a list of what three cameras together can and cannot prove. Ball-tracking can prove where the ball pitched, but cannot conclusively prove exactly where it would have hit the stumps. UltraEdge can prove a sound occurred, but cannot conclusively prove the sound came from the bat. Hot Spot can prove where the bat was struck, but cannot prove whether the ball touched the ground before being caught. Each technology answers one question and leaves the rest to the others.

This is why I say a review system is not a single truth-machine — it is a coalition of three incomplete witnesses. One witness speaks of the preferred ball, another of the preferred sound, the third of the preferred contact. My job as adjudicator is to reconcile the three testimonies, and while reconciling, to admit where each witness leaves a gap. The absence of that admission is Asian cricket's biggest shortfall.

I remember 2026, when from the box room above my Didsbury garage I launched a weekly review channel. It was a 2.6 by 2.1 metre room, a microphone, a ring light. That box-room broadcast taught me that six to eight minutes are enough to explain a decision — if the decision is stated first and the context after. That lesson now applies directly to the review debate. The audience wants to hear the decision first, the explanation second. Yet Asian broadcasters still give context first and the decision last. The audience's patience runs out, and controversy is born.

Contrarian Angle: Emotion Versus Law

The crowd's certainty and the law's certainty are never the same. The crowd knows the ball hit the stumps — because they have seen it three times in slow motion. But the law knows slow motion is evidence, not truth. If the frame rate of slow motion is low, the truth between two frames is lost. Here lies the difference between emotion and law.

As a player I know what the body says at the moment of contact. As an umpire I know what Law 12 does with that feeling. Standing between these two knowledges, I have seen that a player's emotion is almost always honest, but that emotion often does not know the law. A batsman was certain the ball hit his bat, because he felt a vibration in his hands — but that vibration could also come from his pad.

The biggest trap of the review is to treat the replay as a perfect witness. But the replay does not know what frame rate is, what camera calibration is, what the tolerance of ball-tracking is. Hiding these ignorances, no decision can be called 'final'. Much of the review controversy in Asian cricket is really a silent protest against this concealment.

Toward a Takeaway: The Next Step of Technology

In 2026, at the Qatar World Cup, a goal in the Japan-Spain match was ruled valid by 1.88 millimetres — that is a football event, but it is a signal for cricket too. In future, automated leg-before and automated no-ball systems in cricket will grow more precise, and those numbers of precision will become public.

My advice is clear — every millimetre figure should be published with its tolerance. The camera's frame rate, the margin of error of ball-tracking, and every step of the protocol should be shown on the broadcast. Since Asian boards are the biggest funders of the technology, their responsibility is also the biggest — to ensure transparency. I have seen this match from three angles, and the truth is still caught in the replay; the only question is this — will we make that replay credible, or merely keep using it.
