Refereeing at Major Tournaments: How Technology Redraws the Line of Fairness
The 88th minute of a knockout match. The score is 1-1, a high ball is swung into the box, the home defender leaps to challenge, and the ball strikes his arm. The referee stands fifteen metres away, his view blocked by two shirted bodies. He does not blow his whistle. Three seconds later, his earpiece crackles. The VAR room calls down. On the stadium's big screen, fans watch frame after frame in slow motion, angle after angle, line after line drawn along the trailing heel of the last defender. Three minutes pass, long as extra time. Then the referee points to the penalty spot. The stadium erupts. In my ear, the roar mingles with another sound: the whisper of technology.
I once held the whistle. I once stood in the position where a single decision could change the fate of a match, a club, an entire football culture. "There were games I refereed badly, but from them I learned what fairness means." That sentence is not an excuse for error. It is the starting point for every analysis I have written since, because fairness in football is not a feeling; it is a standard built, measured and defended with data.
Across more than three decades of watching and working in the game, I have seen officiating move from total dependence on the referee's eye to a shared decision-making process with machines. In 2026, the International Football Association Board (IFAB) formally approved trials of the Video Assistant Referee (VAR). At the 2026 World Cup in Russia, VAR appeared at a World Cup for the first time. Four years later, at Qatar 2026, semi-automated offside technology came into operation, cutting the time needed to confirm an offside from tens of seconds to a few seconds in most situations. "In 2026, the whole football world turned upside down, and I learned to stand still and watch the storm."
That milestone marked a shift in how football defines fairness. The referee is no longer the sole owner of truth. He has become one node in a system of dozens of cameras, a ball sensor, and an operations room thousands of kilometres away. Power has been distributed; responsibility has not. The person with the whistle still signs the final decision, even when that decision is fed by data from many sources.
Offside is the clearest example. The offside law dates to the nineteenth century, when football was a game of gentlemen in white shirts. Over more than a hundred years, the core principle has barely changed: an attacker may not stand closer to the opponent's goal than the last defender at the moment a teammate plays the ball. What has changed is how the moment and the position are determined. The human eye once judged by feel. Technology judges in millimetres.
Semi-automated offside runs on twelve dedicated cameras mounted under the stadium roof, tracking twenty-nine data points on each player's body, plus a sensor inside the ball that records the instant it is struck. The system reconstructs the situation in three dimensions, draws the offside line and sends an alert to the VAR team within seconds. Where the referee once had to wait, the machine now waits for the referee. Yet that very precision creates a paradox: as the margin of error is compressed to a few centimetres, arguments rage more fiercely than ever over a toe, a heel, a shoulder.
I have reviewed hundreds of such situations. What troubles me is not whether the machine is right or wrong, but the question behind it: is a goal disallowed because a heel crossed a line by a few millimetres truly fair in a game played at human speed and instinct? At first I defended absolute precision. Later I realised the offside law exists to prevent a clear advantage, not to prosecute a deviation the naked eye cannot see. Technology measures something the law never defined.
Handball is a different and far more complex story. The handball law has been amended repeatedly in recent years. In 2026, IFAB tightened the rule: a handball leading to a goal or a goal-scoring opportunity would be penalised strictly, even if accidental. That rule produced a wave of controversial incidents, where the ball brushed an attacker's arm before he assisted or scored. The following season, the law was loosened again. Today, referees must judge whether the arm is in an unnatural position, and whether the contact came off the player's own body.
This is where technology reaches its limit. A camera can show which second the ball touched the arm, from which angle, at what speed. A camera cannot read intent. Unnatural position is a concept defined by humans, and each referee defines it differently. I once sat in a VAR room and listened to two assistants argue over the same incident for ten minutes while the referee waited on the pitch. In the end, the decision belonged to one person, who had to answer to millions of viewers. That is a burden machines cannot share.
The 88th-minute penalty is a chapter of its own. Many believe a penalty depends on the striker's technique or the goalkeeper's talent. For me, it depends on the psychology of the person with the whistle. In the closing minutes, with the score fragile and every mistake remembered, the referee must make one of the two hardest calls of his career: award the penalty and face the fury of half the stadium, or wave it away and face the fury of the other half. VAR can confirm or overturn the call, but it cannot carry the psychological weight. The 88th-minute penalty has little to do with technique; it is a test of nerve for the man at the centre of the storm.
In the operations room, the threshold for intervention is clear and obvious error. The VAR team may only call the referee for a clear error or serious missed incident involving a goal, a penalty, a direct red card, or mistaken identity. Borderline situations, where a decision could be right or wrong depending on how you look, fall outside the scope of intervention. This principle is designed to protect the referee's authority, yet it is also the source of endless argument. In the same incident, a viewer at one camera angle sees a clear foul; a viewer at another sees a fair challenge.
The on-field review is also a standardised ritual. The referee runs to the pitch-side monitor, reviews the incident himself, then upholds or changes the decision. Reviewing it himself is meant to keep the referee in control rather than being directed remotely. In practice, pressure from the stands, the players, and the VAR team turns that moment into a public performance. With every passing second, the tension rises. The final decision, right or wrong, must be delivered under the gaze of dozens of cameras.
Match management is the hardest skill to teach. A good referee applies the laws and reads the rhythm of the game, sensing when to show a card to cool things down and when to stay silent and let the match flow. I learned this through games I refereed badly. In one, I showed a card too early and turned an ordinary match into a war. In another, I let too many fouls pass until the game shattered into scuffles. The laws can be learned from a book, but the ability to manage twenty-two tense players comes only from experience. Technology cannot help here. It intervenes only after an incident has happened, while the referee must live through every second of the match.
Data from major tournaments paints a thought-provoking picture. The number of decisions overturned by VAR at each World Cup is usually a small share of all incidents reviewed, yet those incidents dominate post-match debate. A corrected error creates a sense of fairness, but a missed error or a controversial intervention erodes trust far faster than it builds it. Trust in referees, like trust in any institution, is built by thousands of correct decisions and can collapse with a single wrong one.
There is one thing I always remind myself when analysing: what the camera does not see. Every angle is a perspective, and every perspective has a blind spot. A camera behind the goal cannot see a shirt-pull behind a player's back. An overhead camera cannot see a player's eyes before a collision. A slow-motion camera cannot capture the true speed of the play. The referee, standing in the middle, may see what the cameras miss, but may also miss what the cameras capture. "Every argument in the stands and on the pitch has an answer in some camera angle." But that answer is only complete when we accept that some camera angles do not exist.
There is a counter-intuitive paradox few people notice. The more precise the technology, the higher the fans' expectations, and the greater the disappointment when something goes wrong. When the referee had only his own eyes, people accepted error as part of the game. With VAR, people expect error to vanish entirely. But error does not vanish. It merely shifts from a failure of observation to a failure of interpretation. Machines supply data, humans interpret it, and in the gap between data and interpretation, argument still blooms as before. This is the blind spot of absolute faith in technology: technology does not replace judgement, it only changes the raw material of judgement.
"In the season without crowds, with only the steady hum of cameras, I began to hear the whisper of technology." In those months, when stadiums stood empty and only the sound of machines remained, I realised that VAR, cameras and sensors do not make football colder. They expose what was already cold in how we treat the person with the whistle. We want referees to be perfect, but we do not grant them the right to be wrong. We want absolute technology, but we do not accept that technology is also designed, operated and interpreted by humans.
Looking ahead, the trend toward automation will go further. Semi-automated offside is being extended to more competitions. A sensor in the ball can determine the moment it crosses the goal line without the human eye. AI-assisted foul-detection systems are being trialled. Yet no matter how far machines advance, a man or woman will still stand in the middle, hand on earpiece, answerable to tens of thousands in the stands and millions on television. That person will never be perfect. And precisely for that reason, fairness will remain a continuous process of correction, not a state to be achieved.
"Walking out alone with the whistle, sitting before a screen with the straight-on view, in the end I am still the one standing at the centre of the storm." I write these lines not to defend referees, nor to attack technology. I write to remind readers that behind every offside line, every slow-motion frame, every controversial decision, there is a human being trying to do the right thing in less time than a breath. Football will keep changing, the laws will keep being rewritten, and machines will keep learning to blow the whistle. But the biggest question remains unanswered: are we seeking fairness, or are we seeking a perfection that does not exist, so that we never have to accept that humans, even with technology's help, remain at the centre of every decision?
