The Red Card at Lach Tray and the Loophole Built into Law 12

The 68th minute at Lach Tray. The whistle screams, and a red card is thrust straight at the home side's centre-back. The stands erupt. On the VAR monitor, the slow-motion replay shows a challenge from behind — but the ball is already gone, and the force of contact sits at a moderate level. I stayed behind in the newsroom, opened Law 12 of the IFAB handbook, and read it a third time, then a fourth. What I found was not the fault of one man, but a loophole written into the wording of the law itself. Seven years ago, this exact scenario was why I started writing about the rules. That night, my analysis reached 45,000 reads, nine times the channel's average. The editorial board asked me to open a dedicated column. But the deeper lesson lay elsewhere: a red card is never just a red card. Behind it sits an entire chain of decisions — the referee's, the VAR team's, the rule-drafter's, and that of a football culture still learning to accept technology. A refereeing error is never an isolated event — it is the whole rulebook auditing itself. In the V.League, the VAR debate has run for several seasons. Fans remember it through controversial moments; I remember it through lines of text revised again and again. The semi-automated offside technology (SAOT) that the VFF refereeing board once folded into a 2026 pilot promised to cut offside-line error from 0.4 metres down to 0.1. That number sounds convincing. But when I sat inside the VAR operations room in Qatar during the 2026 World Cup semi-final, what I realised had nothing to do with the number. The system plotted players' skeletal positions in three dimensions, accurate to the toe joint. Yet the final decision still rested on a human pressing a button. And the choice of frame — which frame counts as the first point of contact — was never SAOT's to make. That is a technician's judgement call. Which means the biggest error margin in modern technology is not in the hardware, but in the human step inserted in the middle. People see the red card; I see the clause that was written too hastily. Return to Law 12. The provision on serious foul play requires the referee to weigh three elements at once: the force of the challenge, the speed of the player, and the danger posed to the opponent. The problem lies in the word danger. Danger is a probabilistic concept, not an event that has already happened. A challenge can end harmlessly yet still carry high potential danger, and vice versa. The law grants referees the right to judge based on potential, but hands them no concrete scale to quantify that potential. This is a structural weakness. At the level of major competitions, referees are trained on one shared set of criteria, so consistency is relatively high. In the V.League, where the refereeing pool is thin and match density is heavy, the same challenge can yield three different verdicts across three rounds. Not because the referees are poor, but because the law permits too much interpretive freedom. The data I have tracked across several seasons reveals a paradox. VAR interventions on fouls have risen, but post-match controversy has risen with them. Once technology appears, fan expectations are pushed higher: if there is VAR, mistakes should no longer be allowed. When a wrong decision still happens, the disappointment runs deeper than in the pre-technology era. Technology does not erase controversy; it merely shifts controversy from the referee to the technician. At Euro 2026, I ran a series comparing data from 48 matches and pointed out that the VAR error rate at that tournament was 1.8 times higher than at the 2026 World Cup. One of the most striking moments was Spain's opening goal against Switzerland in the quarter-final, when striker Ferran Torres stood 0.3 metres offside yet the goal stood, simply because the VAR-room technician failed to draw the offside line on the frame. The fault was not in the equipment. The fault was in the process. And here is the counter-intuitive angle: what is costing Vietnamese football credibility is not the scattered errors of referees, but how we handle those errors. After every controversial round, the familiar reaction is to demand discipline, demand suspension, demand a change of whistle-blower. Rarely do we ask the reverse question: which clause in the law created the conditions for that error to recur? If the answer stops at the individual, then next season another referee will make exactly the same mistake. I once drafted a 15-page handbook on contract clauses affected during the lockdown period, and the VFF sent that document to 28 member clubs. The lesson was clear: people do not need more criticism, they need a process to follow. Football is no different. To reduce VAR controversy, the first task is not to buy more cameras, but to write a clear set of criteria for the frame-selection step, then publish it for clubs and fans alike. Amending a law takes ten minutes; admitting the law is wrong takes ten years. What I want to see next season is not flawless VAR — that does not exist. I want to see a transparent process: which frame the technician chose, on what criteria, and why the final conclusion was reached. A mistake that is fully explained will spark less controversy than one that is hidden. When referees dare to let the law interrogate itself, trust finally has somewhere to grow.
