The short answer
“Clear and obvious error” is the standard for changing the referee’s original decision during a VAR review. A replay showing an alternative interpretation is not always enough. The protocol also allows intervention for a serious missed incident, but only within the decisions VAR is authorised to review.
The distinction matters because VAR is designed to correct important errors, not to re-referee every tackle and disputed call. For a complete list of eligible incidents, see what VAR can review.
Why the original decision matters
Under IFAB’s protocol, the on-field referee must make an initial decision. That may be a whistle, a card or a decision to allow play to continue. The referee is not supposed to reserve judgment and ask video officials to decide the incident from scratch.
For a reviewable decision, the VAR studies available footage to establish whether there is a sufficiently clear reason to recommend a review. The mere existence of a closer camera angle does not prove the original decision wrong.
This creates an important difference between “I would have called it differently” and “the available evidence clearly demonstrates that the original call was mistaken”. In borderline subjective situations, the first can be true without the second being established.
Factual questions versus subjective judgment
Some review questions are largely factual: where a foul occurred, which player was involved or whether an attacker was in an offside position when the ball was played. Video, calibrated lines and tracking data can help establish such facts.
Other questions depend on interpretation: whether a challenge was sufficiently serious, whether contact constituted a foul or whether an arm position made the body unnaturally bigger. The handball law is a useful example of why contact shown in slow motion is not automatically proof of an offence.
IFAB recommends that slow-motion footage mainly support factual checks, while normal-speed footage helps assess intensity and natural movement. Selecting only the most dramatic frame can distort the impression of a challenge.
Why two similar incidents may be treated differently
Two clips can look alike but differ in an important factual detail. They may also involve different initial decisions, camera angles or thresholds for intervention. A “check complete” message does not mean VAR positively endorsed every part of the referee’s reasoning: it means the check did not establish a reason to intervene under the protocol.
In addition, reviews happen within a limited set of incident categories. A challenge that is not a reviewable red-card incident may remain outside VAR’s scope even if supporters consider it a foul. To understand the sequence between a routine check and a formal on-field review, read our VAR check versus review explainer.
Common questions
Can the referee disagree with VAR?
Yes. The VAR recommends; the referee takes the final decision, sometimes after looking at footage at the monitor.
Does a long VAR check mean a mistake happened?
No. Extra time can reflect a complex search for footage or the need to establish relevant facts, rather than a clear error.
Is the threshold the same as “any contact”?
No. Physical contact is a fact, while the existence and seriousness of an offence are separate questions under the Laws of the Game.
