A broken or tampered shuttle: when it is a let and when it is a breach
What the Laws say when a shuttle falls apart during a rally, and why you must not alter a shuttle to change its flight.
Why read this
Two Laws touch the shuttle's condition during a match: one about a shuttle that breaks (Law 14), one about a player who alters it (Law 16) (BWF Laws of Badminton, edition in force 26 April 2025).
The shuttle disintegrates: a let
It is a let if, during play, the shuttle disintegrates and the base completely separates from the rest of the shuttle (Law 14.2.4). When a let occurs, play since the last service does not count and the player who served last serves again (Law 14.3). This is not a fault: nobody scores.
Altering a shuttle: not allowed
A player shall not deliberately modify or damage the shuttle in order to change its speed or its flight (Law 16.6.2). The umpire administers a breach of Law 16.6 with a warning to the offending side; with a fault on a side that was already warned; or with a fault straight away in cases of flagrant offence or breach. After a fault for this, the umpire reports the side to the Referee, who has the power to disqualify it from the match (Law 16.7).
Two situations to keep apart
- Accident: a shuttle that breaks by itself is a let only if the base completely separates (Law 14.2.4).
- Intent: bending or pinching feathers to change how the shuttle flies is a breach of Law 16.6.2.
Limits
- The Laws do not say what to do with a shuttle that is damaged but not completely separated (a bent skirt, missing feather). Between rallies, officials and players decide whether to change it; the Laws give no rule, so we do not invent one.
- "Deliberately" is judged by the umpire; the Laws give no test of intent.
- Law 14.2.7 (any unforeseen or accidental situation) can cover other cases, at the umpire's judgment.
General practice advice: play within your limits and stop if something hurts.
