Six Years of VAR: Referees, Data and the Limits of Absolute Justice

On June 16, 2026, at Kazan Arena, the France–Australia match in Group C of the 2026 World Cup reached the 58th minute. Antoine Griezmann burst into the box, collided with defender Josh Risdon and went down. Referee Andrés Cunha of Uruguay shook his head and waved play on. The stands erupted. He raised a hand to his earpiece, walked to the pitchside monitor, reviewed the incident, and pointed to the penalty spot. Griezmann beat goalkeeper Mathew Ryan. It was the first penalty in World Cup history awarded through video assistant referee technology. What I remember from that afternoon in Moscow was not the shot. It was the silence before it, when an entire stadium held its breath waiting for a man to decide rather than for a ball to move. VAR was created to shorten that silence. Six years on, it has stretched it out. FROM TRIAL ROOM TO MANDATORY RULE Video assistant referee technology was approved in principle by the International Football Association Board (IFAB) in 2026, after years of closed trials in domestic leagues. At the 2026 World Cup in Russia, VAR was applied in full for the first time at the game's biggest international tournament. It has since spread to almost every top league: the Premier League, La Liga, Serie A, the Bundesliga, the Champions League, and South Korea's K League 1. K League 1, the competition I have followed for six years as a data analyst and later as a writer on refereeing law, adopted VAR from the 2026 season. The league has 12 teams playing a triple round-robin, 38 rounds in total. With close to 230 matches a season, it is one of Asia's densest data laboratories: every foul is logged, coded and classified under Law 12 and Law 15 of the Laws of the Game. The difference between a league with VAR and one without does not lie in the number of errors. It lies in how errors are recorded. When every incident can be reviewed, referees are forced to justify each decision through a legal framework, or at least through a precedent. Every free kick is a precedent, and every precedent is a case law. WHERE THE CONSISTENCY PROBLEM LIES In 2026, while working as a sports data analyst in Busan, I was assigned to review all 38 rounds of K League 1. I began logging every foul by Ulsan Hyundai, a physically imposing, contact-heavy side. Across 214 fouls, referees issued nine red cards. Yet within the same dataset, six challenges I rated as very high injury risk ended with only a yellow card. No error code explains the gap. No article of the law permits a dangerous challenge to be treated lightly merely because it happens in the 12th minute rather than the 88th. It took me three weeks to write a 47-page report on that pattern of inconsistency. Because of my perfectionism, I delayed sending it while rechecking every figure, and my editor had to chase me three times. But the process taught me something: referee inconsistency is rarely a conspiracy. It is a product of pressure. That pressure can be measured. In domestic leagues, home teams tend to be awarded more penalties than away teams, and the ratio holds steady across seasons and countries. Big clubs, those with large crowds, close media coverage and deep budgets, tend to receive a certain leniency in contested challenges. This does not require a secret investigation to prove. It sits in the data; few bother to read it. TECHNOLOGY DOES NOT ERASE THE GREY ZONE, IT RELOCATES IT When VAR arrived, the great hope was that it would eliminate inconsistency. Machines do not know which club is big and which is small. Machines do not hear the roar. But after six years, I have to say it plainly: VAR does not fix mistakes, it relocates them. The problem is that VAR does not make decisions itself. It only offers an extra angle to a referee, who must still interpret the law. And football's laws, at their key points, are written in open language. "Clear and obvious error" is a phrase with no arithmetic definition. "Excessive force" is a judgement. "Interfering with play" in the offside law is a grey zone drawn by hand. So the same incident can draw two different conclusions from two referees, both legally correct. VAR does not remove that grey zone. It moves it from the pitch into the video room, where a group of people sit before screens and decide whether to call the referee over. And that decision, whether to intervene at all, is the least scrutinised step in the entire process. The grey zone does not need light; it needs a referee who knows how to stay silent, who understands that sometimes not intervening is itself a ruling. THE PRICE OF ABSOLUTE JUSTICE The 2026 World Cup saw a record: more penalties were awarded than at any previous World Cup. A large share came from VAR reviews. Football became fairer in legal terms, but also slower, colder and less surprising. In the France–Australia match, when Cunha pointed to the spot, the stands did not roar with joy. They waited. They waited for a confirmed decision rather than a burst of emotion. Griezmann's goal arrived after a procedure. It was correct, but it was no longer an explosion of feeling. This is the loss few put on a spreadsheet: football was born as a story, not a verdict. When every goal must pass inspection, the narrative of a match is cut into fragments. Viewers learn to wait rather than to believe. But I do not want to fall into the nostalgia trap. Calling VAR the killer of beautiful football is a convenient simplification. Before VAR, refereeing errors also robbed small clubs of justice, only it happened in silence, unrecorded, with no one held accountable. An unrecorded error is not a lesser error. It is merely an error with no precedent. So where does the real price lie? It lies in the fact that we traded one kind of injustice that was easy to see for another that is harder to see. The old injustice played out on the pitch, where everyone could see it and everyone could be outraged. The new injustice sits in a closed room, behind a technical process, presented through lines and frames, and therefore harder to challenge. THE LINE BETWEEN A REFEREE AND A READER OF THE LAW After six years of watching VAR, I have drawn a conclusion rarely stated: technology does not make referees better, it makes them more transparent. Those two things are not the same. A good referee is someone who can read a match, who knows when a collision is an accident and when it is intent, who knows when to stay silent and let the game flow. VAR cannot teach that skill. It only forces referees to state a reason for every intervention. And when forced to state reasons, people tend toward the safest option: intervene more, whistle more, let the game run itself less. In the K League, I have seen matches chopped up by reviews. A referee runs to the monitor, watches an unclear challenge again and again, then upholds his original decision, three minutes later. Those three minutes restored justice to no one. They restored only a confirmation. During those three minutes, the rhythm died and both teams lost momentum. This leads to a paradox: more technology means more procedure, and more procedure means more chances for the grey zone to appear where no one expects it, inside the process itself. A referee can be technically right and managerially wrong. And football's laws, however thick, still contain no article that deals with that kind of error. WHAT NEEDS TO CHANGE No one is calling for VAR to be scrapped. It is a tool now woven into the structure of modern football. But the way we operate it needs to be rewritten. One of the system's biggest blind spots is the decision on whether to review at all. Fans hear the reasoning of the on-field referee but never the reasoning of the VAR team. A public exchange between the two would turn the grey zone into verifiable data. Alongside that, there needs to be a clear threshold for intervention, instead of letting "clear and obvious error" be interpreted at will. If an incident takes more than 90 seconds to resolve, that is a sign it is not clear, and in that case, the on-field decision should stand. More important than either is training referees in match management alongside technology. A referee who can read a game will use VAR less, and use it better. From my experience following hundreds of VAR matches in both the K League and European competitions, I believe the problem is not the machines. It is that we have handed the machines a task they cannot perform: judging in place of people. Technology can give us another angle. It cannot give us judgement. And judgement, in the end, is what makes a referee, just as it makes a match. Six years after that penalty in Kazan, I still believe football needs fewer perfect verdicts, and more referees brave enough to sometimes keep the whistle down.
