Badminton Faults and Lets

Faults

Players win a rally by striking the shuttlecock onto the floor within the boundaries of their opponents' court. Players also win a rally if their opponents commit a fault. The most common fault in badminton is when the players fail to return the shuttlecock so that it passes over the net and lands inside their opponents' court, but there are also other ways that players may be faulted. The following information lists some of the more common faults.

Several faults pertain specifically to service. A serving player shall be faulted if he strikes the shuttlecock from above his waist (defined as his lowest rib), or if his racket is not pointing downwards at the moment of impact. This particular law was modified in 2006: previously, the server's racket had to be pointing downwards to the extent that the racket head was below the hand holding the racket; and now, any angle below the horizontal is acceptable.

Neither the server nor the receiver may lift a foot until the shuttlecock has been struck by the server. The server must also initially hit the base (cork) of the shuttlecock, although he may afterwards also hit the feathers as part of the same stroke. This law was introduced to ban an extremely effective service style known as the S-serve or Sidek serve, which allowed the server to make the shuttlecock spin chaotically in flight.

Each side may only strike the shuttlecock once before it passes back over the net; but during a single stroke movement, a player may contact a shuttlecock twice (this happens in some sliced shots). A player may not, however, hit the shuttlecock once and then hit it with a new movement, nor may he carry and sling the shuttlecock on his racket.

It is a fault if the shuttlecock hits the ceiling.

Lets

If a let is called, the rally is stopped and replayed with no change to the score. Lets may occur due to some unexpected disturbance such as a shuttlecock landing on court (having been hit there by players on an adjacent court).

If the receiver is not ready when the service is delivered, a let shall be called; yet if the receiver makes any attempt to return the shuttlecock, he shall be judged to have been ready.

There is no let if the shuttlecock hits the tape (even on service).
