Law 5: The Referee

3 parts · 5 tests · 50 facts · updated 6 September 2026 · markdown

Law 5 gives the referee full authority to enforce the Laws in connection with a match: the period that authority covers, control exercised in cooperation with the other match officials, the role of timekeeper and record-keeper, the powers and duties around advantage, discipline and injuries, the rules on changing a decision, the compulsory and permitted equipment, the referee's role when video assistance is in use, and the protection of match officials from liability.

5.51The referee's authority and powers

How far the referee's authority reaches and for how long, control of the match in cooperation with the other officials, the role of timekeeper and record-keeper, the power to act on another official's advice and to change a decision before play restarts, disciplinary power over team officials, and the power to stop, suspend or abandon a match for outside interference.

Test 1The scope and period of the referee's authority

  1. The referee's power to take disciplinary action runs from entering the field of play for the pre-match inspection until leaving the field after the match ends.

  2. The referee's authority continues through kicks from the penalty mark, which count as part of the match, and ends only when the referee leaves the field of play afterwards.

  3. Disciplinary authority is continuous from the pre-match inspection to the end of the match, so it covers the half-time interval and a substitute can be cautioned then.

  4. A sending-off offence committed before entering the field for the start lets the referee stop the player starting, and one of the named substitutes takes their place.

  5. The referee controls the match in cooperation with the other match officials; captains and competition personnel have no share in that on-field authority.

  6. As record-keeper the referee provides a match report covering disciplinary action and any other incidents occurring before, during or after the match.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  7. Supervising and indicating the restart of play is the referee's duty; the other officials assist but do not give the restart signal.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  8. A decision may be changed on realising it is incorrect or on an official's advice, but only if play has not restarted and the referee has not ended a half and left the field.

  9. If the referee becomes incapacitated, play may continue under the supervision of the other match officials until the ball is next out of play.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

Test 2Acting on advice, team officials and outside interference

  1. The referee takes action on the advice of other match officials regarding incidents that the referee has not seen, with no restriction to a particular sanction.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  2. Provided play has not restarted, the referee may change a decision on the advice of another match official, so a goal built on a missed offside can be disallowed.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  3. The referee may take disciplinary action against team officials, showing a yellow or red card for irresponsible conduct such as throwing an object onto the field.

  5. A team official expelled for irresponsible behaviour must leave the field of play and its immediate surrounds, which includes the technical area.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  6. Outside interference on the field means the referee stops play; if the extra ball, person or animal interfered with play, the restart is a dropped ball.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  7. The referee has the power to stop, suspend or abandon the match for any offences or because of outside interference of any kind.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  9. Unsafe conditions such as a floodlight failure are grounds to abandon; a one-sided score or a normal sending-off is not.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  10. The referee authorises medical and other personnel to enter the field; they may only come on when the referee signals them on.

5.52Duties: advantage, discipline, injuries and restarts

How and when the referee applies advantage and how long the window lasts, the timing of a card once advantage is played, weighing more than one offence committed at the same time, the handling of slight and serious injuries, the exceptions that let an injured player stay on the field, and how play is restarted after a stoppage for injury.

Test 1Advantage and weighing simultaneous offences

  1. The referee allows play to continue when the team against which an offence has been committed will benefit from the advantage of doing so.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  2. If the anticipated advantage does not ensue at that time or within a few seconds, the referee penalises the original offence.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  3. When advantage is played on a cautionable offence, the caution is still issued but is delayed until the next stoppage in play.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  4. If advantage is played on a sending-off offence and the offender then plays the ball or challenges an opponent, the referee stops play and sends the player off.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  5. When more than one offence occurs at the same time, the referee punishes the more serious one, judged by sanction, restart, physical severity and tactical impact.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  6. Where one act carries a caution and another a sending-off, the more serious sanction applies and the player is sent off.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  7. Advantage can be applied anywhere on the field; if the promising attack does not come off within a few seconds, the referee returns and penalises the foul.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  8. A disciplinary sanction after play has restarted is only possible if another match official identified and communicated the offence before the restart.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  9. Advantage is signalled by extending both arms forward and, usually, calling 'play on'; a raised arm is the signal for an indirect free kick.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  10. The referee weighs the severity of the offence: for one that warrants a sending-off, play should be stopped unless there is an immediate chance to score.

Test 2Injuries, player treatment and restart of play

  1. For a slight injury the referee allows play to continue until the ball is out of play.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  2. For a serious injury the referee stops play and ensures the injured player is removed from the field of play for treatment.

  4. A collision between a goalkeeper and an outfield player who both need attention is one of the listed exceptions to leaving the field.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  5. Where the injury results from a foul for which the opponent is cautioned or sent off, the player may stay and be treated quickly on the field.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  6. An injury to the goalkeeper is an express exception, so the goalkeeper does not have to leave the field for treatment.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  7. Any card is shown before the injured player leaves the field for treatment, so the sanction is recorded against the right player at the right moment.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  8. A player who is bleeding must leave the field and may only return once the bleeding has stopped and after a check.

    Source: IFAB Laws of the Game 2026/27, Law 5 · recall

  9. When play is stopped for injury and no offence has been committed, it is restarted with a dropped ball where the ball was when play stopped.

    Source: IFAB Laws of the Game 2026/27, Law 5 · applied

  10. A suspected concussion is treated as a severe injury: the referee stops play immediately, and such a case is among the exceptions that allow treatment without leaving the field.
