The Video Assistant Referee (VAR) was introduced to fix obvious mistakes, not to re-referee every incident. Most frustration with VAR comes from expecting it to do the second job. This guide explains what VAR is allowed to look at, how a review actually works, and why the same kind of incident can be overturned one week and left alone the next.
The guiding principle: “minimum interference, maximum benefit”
The VAR protocol, written by the International Football Association Board (IFAB), starts from a simple idea. The on-field referee makes the decision, and VAR only steps in for a “clear and obvious error” or a “serious missed incident.” If reasonable people could disagree about a decision, VAR is supposed to leave it alone, even if the VAR official personally would have decided differently.
The four match-changing situations
VAR can only be used for four types of decision:
- Goals and offences leading up to a goal: offside, handball, fouls in the attacking phase, or the ball going out of play before the goal.
- Penalty decisions: whether a penalty should or should not have been awarded.
- Direct red cards: not second yellow cards. A wrongly shown second yellow cannot be reviewed.
- Mistaken identity: when the referee cautions or sends off the wrong player.
Everything else is outside VAR’s remit: a corner wrongly given, a throw-in to the wrong team, an ordinary foul in midfield, a missed yellow card. If a corner is wrongly awarded and the team scores directly from it, the goal stands, because the restart error is not reviewable.
Factual decisions vs. subjective decisions
Understanding this split explains most VAR controversy.
- Factual decisions have a yes/no answer: was the attacker offside, did the ball cross the line, was the foul inside or outside the box. VAR overrules these directly, often without the referee going to the monitor.
- Subjective decisions need judgement: was the contact enough for a penalty, was the tackle reckless or serious foul play, was the handball “deliberate” or an “unnaturally bigger” body position. For these, VAR usually recommends an on-field review, and the referee watches the replay at the pitchside monitor and makes the final call.
This is why a referee sometimes watches a replay and sticks with the original decision. VAR thought it was worth a second look, and the referee still disagreed. The protocol allows exactly that.
How a review happens, step by step
- The silent check. Every goal, penalty incident and red-card incident is checked automatically in the background. Most checks are complete within seconds, and fans never notice them.
- The referee delays the restart. If VAR needs more time, they tell the referee not to restart play. You will see the referee holding a hand to their earpiece.
- The recommendation. For a factual issue, VAR tells the referee the facts and the decision is changed. For a subjective issue, VAR recommends a review.
- The on-field review. The referee draws a rectangle in the air (the TV screen signal), goes to the monitor, watches the footage at normal speed and slow motion, and decides.
- The final decision. The referee makes the TV signal again and gives the final decision.
Why slow motion can mislead
Slow motion is useful for seeing where contact happened, but it can exaggerate how much force was involved. A tackle that looks brutal frame by frame may be a normal challenge at real speed. Good practice is to use slow motion for the point of contact and real speed for intensity. Viewers at home often see only the slow-motion clip, so the decision can look stranger than it is.
Why VAR seems inconsistent
- Different thresholds by competition. Different leagues have set different bars for “clear and obvious.” Some leagues intervene rarely, others more often. The same contact may be reviewed in one competition and not in another.
- The original decision matters. Because VAR only corrects clear errors, two identical incidents can end differently if the on-field referees gave opposite decisions and neither was clearly wrong.
- Handball is subjective. The handball law has been rewritten several times. Judging whether an arm made the body “unnaturally bigger” is still an opinion, not a measurement.
- Camera angles. VAR can only judge what the cameras show. Lower-budget competitions often have fewer cameras, and sometimes no angle clearly shows the key moment.
What VAR cannot do
- It cannot review a second yellow card.
- It cannot go back indefinitely. Reviews of a goal or penalty cover the attacking phase that led to it, not every incident in the build-up from a minute earlier.
- It cannot change a decision once play has restarted, except for mistaken identity and some cases of violent conduct.
- It cannot make the on-field referee take a decision they disagree with on a subjective call.
Communicating decisions to the stadium
One long-standing complaint is that fans in the stadium don’t know what is being checked. Several competitions now show short messages on big screens (“Checking: possible penalty”). Some tournaments have also tested referees announcing the final decision over the stadium PA system, as in other sports. Expect this to keep expanding, because transparency is the easiest way to reduce anger about decisions.
Key takeaways
- VAR exists to fix clear and obvious errors, not to find the “perfect” decision.
- Only four kinds of decision can be reviewed: goals, penalties, direct red cards and mistaken identity.
- Factual errors are corrected directly. Subjective ones go to the referee’s monitor.
- Inconsistency usually comes from different thresholds and the original on-field call, not from the technology itself.
