Law 11, the Arm and VAR: Why the Argument in V.League Has Not Ended

In July 2026, I published a short blog after the France–Argentina round-of-16 tie at the World Cup, arguing that Kylian Mbappé’s 64th-minute goal was offside. Two hours later, Simon Talbot replied on Twitter: I was using an outdated edition of the Laws. IFAB had amended Law 11 for the 2026/19 season, ruling that the hands and arms are not considered when judging offside position. It took me three months to understand that the arm does not belong to the offside law.

Those three months involved fifty offside situations from the 2026 World Cup reviewed frame by frame, a printed copy of the Laws of the Game taped across my desk, and a public correction that drew 40,000 readers. My working method changed for good: before concluding anything about a passage of play, I open the text of the Law first and the replay second.

In V.League 1, that memory returns almost every round that has VAR. A goal is disallowed. The stand erupts. The big screen replays a yellow line drawn across a player’s upper arm. The television commentator says “shoulder”. The referee says “offside”. Both sides are arguing from a feeling about a clause of text that neither of them quotes.

This piece takes a different route. I want to show exactly where the legal boundary sits, why the broadcast image almost always puts it in the wrong place, and why the promise that “VAR will deliver justice” cannot be kept by a machine — only by a sentence.

The Laws of the Game are not written by the VFF. IFAB — four representatives of the English, Scottish, Welsh and Northern Irish associations plus four from FIFA — publishes the Laws and updates them once a year, effective 1 June. FIFA, the AFC and member associations may only apply them. V.League 1 began operating VAR in the 2026 season and expanded it through 2026/24 and 2026/25, with VAR teams working to FIFA’s technical standards and AFC guidance.

Which means every VAR argument in V.League is an argument about a roughly 100-page English document, translated into Vietnamese, interpreted by people who did not write it. The gap between the wording and the whistle is where the argument is born.

The cost of VAR belongs in the story too. A standard VAR room needs calibrated camera systems, dedicated fibre links, line-drawing equipment and officials trained under AFC programmes. No Southeast Asian league could roll this out across every fixture in the first season, so V.League expanded gradually. That is operationally sound, but it produces an effect rarely discussed: within a single season, an identical passage of play may be reviewed by VAR in one round and not in another. Fans do not compare referees with referees. They compare rounds with rounds.

Law 11 has been amended at least four times since 2026. Before 2026/19, offside was judged on “any part of the body”, so a thread of an upper arm was enough to put a player in an offside position. From 2026/19, IFAB ruled that the hands and arms of all players, goalkeepers included, are not considered; the upper boundary of the arm is in line with the bottom of the armpit. In 2026/20 Law 12 was rewritten in full and also set the armpit as the boundary between shoulder and arm. In 2026/22 IFAB removed the rule treating any handball above shoulder level as an offence, replacing it with the “unnaturally bigger” test. In 2026/24 the concept of “deliberate play” in offside was clarified by another layer.

The VAR protocol has two entry points: a clear and obvious error, or a serious missed incident. Offside belongs to the category of factual decisions, meaning the referee need not review the screen himself if the VAR team can establish position. That word “factual” feeds a dangerous belief: that offside is a measurement rather than a judgement.

Law 11 and Law 12 share a single anatomical boundary: the bottom of the armpit. One armpit line decides both offside and handball — and it decides in opposite directions.

For offside, every part of the body from the armpit upward — head, torso, shoulder — can place a player in an offside position. Anything below does not. A striker whose arm extends 40 cm beyond the last defender is entirely legal if the rest of his body has not crossed. That is why goals that “look offside” are sometimes awarded, and why nobody in the stand can be told why.

For handball, the same armpit line produces the reverse outcome. Contact at or below the armpit is judged as handball. Contact above it is the shoulder, and legal. One arm, one line, two chapters of Law, two contradictory conclusions. A player can escape an offside call with his arm and be penalised ten minutes later for that same arm.

Supporters cannot see the armpit. They see the broadcast line. And that line is usually drawn at the shoulder, the toe, the sleeve — visible landmarks rather than legal ones. The gap between the two on an adult player can reach 15 to 20 cm. That is the entire margin of a phase of play.

There is another layer of error that is rarely discussed. A player sprinting at 30 km/h covers 16.7 cm in 1/50 of a second — the length of one standard broadcast frame. The ball leaves the foot at a moment between two frames. The line is drawn on the frame nearest that moment, with an average error of roughly 8 cm. In phases separated by 3 cm, the measurement error is larger than the object being measured.

Each camera angle is also a perspective projection, and calibration error grows toward the edge of frame. FIFA’s technical standards require a minimum of four cameras for VAR and recommend more for offside situations. In V.League, the number of angles available for an offside phase is typically lower than in European leagues. That is an infrastructure limit, not a limit of refereeing ability — and it is not something a post-match press conference can erase.

Semi-automated offside technology operates at a different level. It uses 12 cameras mounted under the stadium roof, tracking 29 data points per player 50 times per second, so the kick point and body positions are captured almost simultaneously. Launched at the 2026 World Cup and adopted by UEFA from 2026/23, it cut average review time from around 70 seconds to around 25. It solves the frame problem. It does not solve the armpit problem, because the armpit still has to be defined by people in a text.

Here the protocol contradicts itself. VAR may intervene only for a clear and obvious error. Yet once the line is drawn, that threshold disappears: a 3 cm gap is enough to overturn a decision, even when the measurement error exceeds 3 cm. At precisely the point where caution matters most, the protocol is suspended. Fans see absolute precision; the VAR team sees a confidence interval narrower than the error.

In 2026/24 IFAB clarified another layer of Law 11: a defender who plays the ball without time to adjust is not considered to have made a “deliberate play”. So a defender’s touch no longer automatically cancels offside. Fans see the defender kick the ball and assume offside is void. The referee reads the clause and still gives offside. Both are describing different editions of the Law inside the same frame, and neither is logically wrong.

Law 12 sits at a harder level still. The “unnaturally bigger” test is a judgement clause, not a factual one. No VAR can repair a judgement clause. VAR can only ask whether that judgement was clearly wrong, and with an open clause the answer is almost always no. Which is why every handball debate ends not with data but with a citation, or the absence of one.

An expired clause still says more than an infinite promise. The pre-2026 text no longer has force, yet it lives on in the reflexes of millions of viewers: arm ahead means offside. IFAB changed the wording; nobody has changed the reflex. Most arguments in V.League, I would argue, are not between referee and coach but between the 2026/25 Law and the 2026 Law still stored in the memory of the stand.

Based on my experience covering matches in both V.League 1 and the A-League, I see a repeating pattern: the decisions that provoke the most anger are not the wrong ones, but the right ones explained in language the stand cannot parse. A referee saying “offside” is a conclusion. A referee saying “the body crossed the armpit of the last defender” is an explanation. The distance between those two sentences is the distance between a small riot and a healthy argument.

Fans’ demand for consistency is legitimate, but it cannot be met by adding machinery. While Law 12 retains the word “unnatural”, two geometrically identical handballs can produce two different outcomes from two different referees — and both are correct under the Law. Demanding consistency from a system with open clauses is demanding something the system cannot give. The honest alternative is to say plainly which parts of the Law are measurement, which are judgement, and who answers for the judgement.

A mistake is a footnote; only silence is a verdict. When the VAR team and the referee confer and the stand cannot hear them, that void is automatically filled with the worst available hypothesis. Europe’s leading competitions have begun releasing VAR audio after each round, alongside the line images and the clause numbers. Publication raises argument in the short term and lowers suspicion in the long term, because it moves the question from “was there cheating” to “was this reading correct”. The second question belongs to football. The first belongs to a courtroom.

There is a final paradox the technology people in football rarely concede. When a system is advertised as accurate to the millimetre, the residual error becomes harder to forgive than ever. A referee without VAR who is 5 cm wrong gets “he could not see it”. A system with VAR that is 5 cm wrong gets “you saw it and still got it wrong”. The more precise the tool, the less tolerance remains for the imprecision that survives.

Reviewing the tape is not a lack of trust; it is how the truth is respected. And respecting the truth, in this case, includes admitting that some questions cannot be answered by footage — because the answer lives in the wording, not in the frame.

Fans remember the goal; I remember the clause. A goal disallowed in the 89th minute will be discussed for a few days. Law 11 and Law 12 will go on deciding thousands of goals, across hundreds of competitions, for many seasons. If V.League wants fewer arguments, the answer is not more cameras but more words: a monthly VAR report, each decision listed with the Law number, the clause, the line image and the camera specification. Three pages a month is far cheaper than a season of suspicion.

A final question for the people running the competition: if a decision cannot be explained by a Law number and a clause, should it be given at all?
