Yellow warns, red faults, and black disqualifies.

What each badminton card means

• Yellow card — warning for misconduct: the umpire identifies the breach and formally warns the offending side. It does not award a point.
• Red card — fault for misconduct: during the match, including an interval, the opponents receive the point consequence and become or remain the serving side. The umpire calls the Referee and reports immediately. A red card before the opening call of “Play” is a specific exception: ITTO 5.17.10 says it does not alter the starting score.
• Black card — disqualification for misconduct: the Referee, not the umpire acting alone, decides to disqualify. The umpire displays the black card and announces the match for the opponents.

Under BWF Law 16.7.1, the relevant history is whether the side has already been warned in that match, not whether the same type of misconduct has recurred. A red card brings the Referee to court; it does not predetermine a black card.

The Laws create the sanctions; officiating instructions create the card procedure

This page covers BWF-sanctioned matches with appointed technical officials. It was checked on 13 August 2026 against the BWF Laws of Badminton Version 5.0 (2), principally Laws 7.3, 13.4.5, 13.5, 16 and 17, and the BWF Instructions to Technical Officials (ITTO) Version 8.0, principally Instructions 2.7, 3.6.2, 3.7.3, 5.9, 5.10 and 5.17.

Law 16 creates the warning, fault, report and possible disqualification. It does not assign colours. ITTO 5.17 creates the yellow, red and black display and announcement procedure. The BWF Players' Code Version 2.0, in force 28 February 2022, supplies additional on-court conduct duties for players at BWF-sanctioned tournaments.

What can become misconduct under Law 16

Law 16.7 applies to breaches of the interval limits in Law 16.2, delaying to recover strength or wind or receive advice under Law 16.4.1, leaving court without permission while causing delay under Law 16.5.2, and the four prohibitions in Law 16.6. Those prohibit deliberately delaying or suspending play, deliberately changing or damaging a shuttle to alter its speed or flight, offensive or inappropriate behaviour, and other misconduct not covered elsewhere in the Laws.

The rule is deliberately broader than a list of words or gestures. ITTO 5.9 gives useful examples but often tells the umpire first to remind the player and apply Law 16.7 “if necessary.” A reminder is match management, not automatically a yellow card. If a formal warning or fault is issued, ITTO 5.17 requires the umpire to name the offending player and give a specific explanation.

The BWF Player Code supplies practical examples

For BWF-sanctioned tournaments, ITTO 5.17.1 treats breaches of Players' Code clauses 3.2.2–3.2.3 and 3.2.6–3.2.15 as Law 16.6.4 offences. They include unsportsmanlike conduct, failing to observe match goodwill formalities, seeking coaching when the Laws do not permit it, trying to influence a technical official, audible obscenity, offensive gestures, dangerous or reckless hitting of a shuttle, racket or equipment abuse, insulting statements, and physical abuse.

The Code also addresses completing a match unless reasonably unable to do so. A genuine injury, illness, or emergency is not misconduct merely because the player retires; the concern is blatant abuse of retirement or an attempt to manipulate the match process.

A warning is formal, but it does not change the score

For an ordinary first breach administered under Law 16.7.1.1, the umpire calls the offending player, announces “warning for misconduct” with the specific explanation, and raises a yellow card. ITTO 5.17.2 requires the incident and action to be recorded and reported to the Referee.

The important consequence is that the offending side is now previously warned for that match's Law 16 sequence. A later Law 16 breach by that side is faulted under Law 16.7.1.2; it need not repeat the original conduct. The yellow is therefore more than an informal reminder even though it adds no point.

A misconduct fault awards the opponents a point

When the umpire faults a side under Law 16.7.1.2 or 16.7.1.3, ITTO 5.17.4 requires the call “fault for misconduct,” a specific explanation, the red-card display, and an immediate call for the Referee. Under Law 7.3, the opponents add the point because the offending side has committed a fault.

If the offending side had the serve, service passes to the opponents. If the opponents already had the serve, they keep it. The next service court and server follow the updated score and the normal singles or doubles order. The exception is a red card shown before the opening “Play”: ITTO 5.17.10 expressly says a pre-match card has no score effect, although it counts if another offence occurs during that match.

A flagrant offence can receive red without yellow first

Law 16.7.1.3 permits the umpire to fault a side immediately for a “flagrant offence or breach.” The player is not guaranteed a yellow card before a point penalty.

The Laws and ITTO do not publish a mechanical severity table defining every flagrant case. The umpire must assess what happened, identify the actual breach and give the specific explanation. Conduct listed in the Players' Code—such as physical abuse, dangerous or reckless shuttle hitting, or violent equipment abuse—can be serious, but the Code does not declare that every instance automatically receives the same card.

The 25-second clock applies only when the tool is in use

ITTO 5.10 distinguishes matches played with and without the Time Clock. When it is used, the clock starts when the umpire enters the previous rally's score and expires after 25 seconds. Both sides must be in position and ready before expiry, although a receiver must also be ready sooner when the server is already ready. The umpire may stop the clock for an extended court wipe, a dispute, an injury or another appropriate reason.

Expiry is not stated to be an automatic red card. Under ITTO 5.10.9 the umpire reminds a player who violates the continuous-play instructions and applies Law 16.7 if necessary. The resulting formal card then depends on whether the side is un-warned, previously warned, or has committed a flagrant breach. Without the tool, the umpire remains the sole judge of delay under Law 16.4.2.

A red card triggers a report, not automatic disqualification

After any misconduct fault, Law 16.7.2 requires the umpire to report the offending side immediately to the Referee. Under ITTO 3.6.2.1, the Referee first receives the facts from the umpire and, if necessary, the service judge; other personnel can be called to court when their information is needed.

The Referee may resolve the matter without disqualification, leaving the red-card point in place, or may disqualify. Play is deemed suspended while the Referee is on or near the court dealing with the incident unless the Referee directs otherwise. Once the Referee has explained the resolution under ITTO 3.6.2.3, there is no further on-court discussion or appeal.

The Referee decides disqualification

If the Referee disqualifies, ITTO 5.17.5 directs that a black card be given to the umpire. The umpire calls the player or pair, announces disqualification for misconduct with the specific reason, raises the black card and announces the match for the opponents.

For a BWF-sanctioned tournament, ITTO 3.6.2.2 says the disqualified player is out of all events at that tournament and, in a team tournament, all future matches of that team tournament. A doubles partner may continue in other events, but the affected pair cannot continue that match. This tournament-wide consequence should not be assumed for a domestic or local event operating different regulations.

The Laws penalise the side, even when one partner acts

Law 16.7 describes the warning or fault as applying to the offending side. In doubles, that means one partner's misconduct can place the pair under a warning and a later misconduct fault against the side awards a point to the opponents.

The umpire names and addresses the offending player when giving the warning or fault, but a partner cannot avoid escalation by arguing that the earlier card belonged only to the other individual. If disqualification follows, the pair loses that match.

Misconduct during an interval can affect the next game

BWF officiating instructions treat misconduct during a permitted interval as misconduct during a game, and the card is shown when the incident occurs. A yellow card leaves the score unchanged. A red-card fault must be reflected when play resumes.

If a red card is issued between games, the completed game remains completed and the penalty point is applied to the next game. The umpire announces the new-game score after the misconduct fault rather than reopening the previous game. If the Referee disqualifies during an interval, the umpire announces it immediately instead of waiting for the interval to end.

Cards on the field of play are not limited to live rallies

Misconduct on the field of play before the initial call of “Play” can receive a yellow, red, or black card. A pre-match card does not change the starting score, but it counts if another offence occurs during the match. This means a pre-match yellow can make a later in-match breach an offence by a previously warned side.

Misconduct on the field of play after the match can also be carded and reported, although it cannot change a match score that is already complete. Conduct elsewhere at a BWF-sanctioned tournament may be handled through the Players' Code and judicial process even when the in-match card procedure is not the appropriate mechanism.

Not every bad act is decided by the card ladder

Some behaviour is already a rally fault under Law 13. For example, deliberately distracting an opponent by shouting or gesturing while the shuttle is in play is a fault. Officials should first identify the rule that decides the rally; related behaviour may also require misconduct action if its nature or repetition justifies it.

Similarly, an ordinary service fault, net touch, or out landing is not misconduct merely because it costs a point. A red-card point is a separate disciplinary consequence under Law 16, not the colour used for routine playing faults.

The field ruling and later discipline are separate

Law 17 makes an official's assigned findings of fact final and permits an unsatisfied question-of-law appeal to the Referee only before the next service, or at match end before the appealing side leaves court. That is not a general video challenge to a misconduct judgment. When the Referee resolves a red-card incident on court, ITTO 3.6.2.3 provides for no further discussion or appeal there.

Separately, ITTO 3.7.3 requires the Referee to send BWF or the relevant Continental Confederation a post-tournament report on withdrawals and yellow/red cards that may trigger further sanctions. Under 3.7.3.1, the Referee may omit a card from that report after personally observing that it should not have been issued. That reporting discretion does not itself say that the match score is retrospectively changed. Any later disciplinary process is governed by the applicable competition and judicial regulations.

How an official reaches the card and score outcome

1. Identify the governing event rules. Confirm that the BWF Laws and ITTO apply and whether the Time Clock tool is in use.
2. Name the breach. Is it an interval, delay, leaving-court or Law 16.6 breach, a Players' Code offence incorporated by ITTO 5.17.1, or an ordinary playing fault under another law?
3. Check the side's warning status in this match. An un-warned side receives a warning unless the offence or breach is flagrant; a previously warned side is faulted.
4. Apply the timing rule. Yellow adds no point. A red during the match or an interval adds the opponent's point; a pre-match red does not alter love-all; a post-match card cannot rewrite a completed score.
5. Escalate a red. The umpire calls the Referee immediately. The Referee resolves the incident and decides whether disqualification is justified.
6. Keep later discipline separate. Record and report as the ITTO and the event regulations require.

Six boundary cases under the current BWF editions

1. BWF Laws Version 5.0 (2), first ordinary delay: an un-warned player deliberately delays before the next service and the umpire formally administers Law 16.7. Ruling: yellow, no point. Decisive fact: the side was not previously warned and the breach was not judged flagrant.
2. BWF Laws Version 5.0 (2), warned doubles side: player A received yellow; later player B of the same pair commits another administered Law 16 breach. Ruling: red against the side, one point to the opponents and the Referee is called. Decisive fact: Law 16.7 warns the side, not only player A.
3. ITTO Version 8.0, Time Clock expiry: the clock reaches 25 seconds while a side is not ready. Ruling: expiry alone does not dictate red; the umpire reminds the player and applies Law 16.7 if necessary. Decisive facts: whether the clock should have been stopped and whether the side was already warned.
4. ITTO Version 8.0, red between games: a previously warned player commits misconduct during the 120-second interval. Ruling: the completed game remains complete; the misconduct point is reflected in the next game's score and service sequence. Decisive fact: ITTO 5.17.6–5.17.8 treats interval misconduct as occurring during a game.
5. ITTO Version 8.0, red before the match: a flagrant offence occurs on the Field Of Play before the opening “Play.” Ruling: red may be shown and counts for later escalation, but the match still starts at love-all. Decisive fact: the express no-score exception in ITTO 5.17.10.
6. BWF Laws Version 5.0 (2), red at 29–29: misconduct is faulted during the current 21-point scoring game. Ruling: the opponents receive the 30th point and win the game; the umpire still calls the Referee to resolve the red-card incident. Decisive facts: Laws 7.3 and 7.5 determine the score, while Law 16.7.2 separately requires the report.

Seven card claims that need correction

• “Yellow costs a point.” No. Yellow communicates a formal warning and leaves the score unchanged.
• “Every first offence must be yellow.” No. A flagrant offence or breach can be faulted immediately.
• “Red means automatic disqualification.” No. Red requires an immediate report to the Referee, who then has power to disqualify.
• “The umpire independently gives black.” No. The Referee makes the disqualification decision; the umpire displays and announces it.
• “A doubles yellow belongs only to one partner.” The offending player is named, but Law 16 warns and faults the side.
• “Nothing can be carded during an interval.” Misconduct during a Law 16.2 interval is treated as misconduct during a game.
• “Reaching 25 seconds automatically means red.” No. ITTO 5.10.9 calls for a reminder and Law 16.7 action if necessary; warning status and the circumstances still matter.

Local badminton may use a different conduct process

This page explains the BWF Laws and BWF technical-official procedure used for matches with appointed officials. A recreational game without an umpire has no neutral official to administer the formal yellow-red-black procedure. Players should use the venue, league, school, national association, or event code that actually governs the match.

National bodies may adopt the BWF Laws while adding their own disciplinary tables, reporting rules, fines, suspensions, or simplified officiating procedures. Those competition consequences should not be presented as universal BWF card effects unless the event is governed by the corresponding BWF regulation.
