VAR does not review incidents. It reviews decisions

The most consequential sentence about video assistance in the Laws of the Game is not the one listing what may be reviewed. It is this one:

Except for a serious missed incident, the referee, and where relevant other on-field match officials, must always make a decision — including a decision not to penalise a potential offence — and this decision does not change unless it is a clear and obvious error.

Reference The requirement that the referee always make a decision, including a decision not to penalise, and that the decision does not change unless it is a clear and obvious error, from Law 5.4.

Read it as a precondition, which is what it is. Before any review can happen, a decision must already exist. And because a decision not to penalise counts as a decision, the referee is required to have formed a view even about things they let go.

That single clause makes VAR a system for auditing judgements rather than for adjudicating events. The video assistant is not asked whether a foul occurred. They are asked whether the referee’s answer to that question was clearly and obviously wrong.

The list is shorter than the discourse

The permitted categories are exhaustive. The referee may be assisted by a video assistant referee only in the event of a clear and obvious error or serious missed incident in relation to:

• goal or no goal,
• penalty or no penalty,
• a red card, including a clearly incorrect second caution,
• mistaken identity when the referee cautions or sends off the wrong player,
• and, as a competition option, a clearly incorrectly awarded corner kick, if the decision can be changed immediately and without delaying the restart.

Reference The five categories of reviewable decision, including the competition-option corner kick and its condition of immediate change without delaying the restart, from Law 5.4.

Nothing else. A missed yellow card is not reviewable. A wrongly awarded throw-in is not reviewable. A foul in midfield that leads, forty seconds later, to a goal is not reviewable as a foul — it can only be reached through the goal decision it produced.

The list is organised around match-changing consequences, not around severity of error. That is why a second yellow card appears and a first one does not: a second yellow removes a player, and the removal is what makes it reviewable.

The corner-kick entry is the tell. It is a competition option, not a requirement, and it comes with a condition attached — the decision must be changeable immediately and without delaying the restart. It is the one category admitted on grounds of cheapness rather than importance. Where a correction costs nothing, competitions may take it.

Two thresholds, not one

The law names two triggers, and they behave differently.

A clear and obvious error presupposes a decision that was made and was wrong. A serious missed incident is the exception to the precondition — the case where nothing was decided because nothing was seen.

That distinction resolves what looks like a contradiction. If the referee must always make a decision, how can anything be missed? Because “must always make a decision” describes what an official is required to do about what they perceive, and a serious missed incident is by definition outside that. The law carves it out explicitly rather than leaving the gap for interpretation.

The consequence for how VAR feels to watch is direct. On a decision that was made, the bar is deliberately high, and the referee’s original call is protected unless it was clear and obvious. On an incident that was not seen at all, there is no original call to protect, and the intervention starts from nothing. The same passage of play can therefore be treated very differently depending on whether the referee formed a view about it — a fact that is invisible on television, because a referee who decided not to penalise looks exactly like a referee who did not see.

Where the final decision sits

The law is unambiguous about authority. The assistance relates to using replays of the incident; the referee makes the final decision, which may be based solely on the information from the VAR, or on the referee reviewing the footage directly in an on-field review.

Reference That assistance relates to replays, and that the referee makes the final decision, whether solely on VAR information or after an on-field review, from Law 5.4.

Both routes are equal in law. A referee who accepts the VAR’s information without looking has decided; a referee who walks to the screen has decided. The on-field review is not an appeal to a higher standard of proof — it is one of two ways the same person can reach the same kind of conclusion.

This is why the review area is regulated as sharply as it is. There must be at least one referee review area, in a visible location outside the field of play, and clearly marked; a player, substitute, substituted player or team official who enters it is cautioned.

Reference The requirement for a referee review area in a visible location outside the field of play, clearly marked, and the caution for anyone entering it, from Law 5.

The video operation room has a stronger sanction still: anyone in those categories who enters it is sent off.

Reference That a player, substitute, substituted player or team official who enters the video operation room will be sent off, from Law 5.

A caution for approaching the screen; a dismissal for approaching the room. The law is protecting the integrity of the process more fiercely than the process itself.

Once play restarts, almost everything closes

The narrowest provision in the whole section is the one governing time.

If play has stopped and restarted, the referee may only undertake a review, and take the appropriate disciplinary sanction, for mistaken identity or for a potential sending-off offence relating to violent conduct, spitting, biting, or extremely offensive, insulting or abusive actions.

Reference The restriction on reviews after a restart to mistaken identity and to sending-off offences relating to violent conduct, spitting, biting or extremely offensive, insulting or abusive actions, from Law 5.4.

Nothing about goals. Nothing about penalties. Once the ball is back in play, the match result is closed to review and only conduct remains open.

The logic is that a restart is a fact the game has built on. Undoing a goal after play has resumed would mean undoing everything since, and the law will not do it. But a red card for violence is a sanction against a person rather than a change to the score, so it can be applied late without unravelling anything — and the categories listed are exactly the offences serious enough to be worth reaching backwards for.

What this means for the argument

Most complaints about VAR are complaints about one of two things the law has already decided.

That it does not correct everything: true, and by construction. Four categories plus an optional fifth, with two thresholds, and a hard stop at the restart. A system that corrected every error would be a different system, and the Laws describe this one.

That it defers too much to the original decision: also true, and also by construction. “Clear and obvious” is a deliberately high bar, and it exists because the alternative is a video official re-refereeing the match from a screen — which the requirement that an on-field decision always exist first is specifically designed to prevent.

Those are legitimate things to disagree with. But they are disagreements with a design, not failures of one. The system in the Laws of the Game is an error-correction mechanism with a narrow remit and a strong presumption in favour of the referee, and it says so in about four hundred words.
