How do I deal with misconduct, and how do the yellow, red and black cards work?

Question

Accepted Answer

Law 16.7 of the BWF Laws of Badminton: for a breach of the interval rules (16.2), delay (16.4.1), leaving the court without permission (16.5.2) or misconduct (16.6), the umpire: warns the offending side; or faults the offending side if it has already been warned; or faults it straight away for a flagrant offence. On faulting a side you must report it immediately to the referee, who can disqualify it from the match. Cards and calls (BWF Instructions to Technical Officials): Action Call Card Warning "Come here", then "[name], warning for misconduct" plus the specific reason Yellow, held up in the right hand above your head Fault "Come here", then "[name], fault for misconduct" plus the reason; call the referee on court Red Disqualification (referee's decision; the referee gives you the card) "[name], disqualified for misconduct" plus the reason, then "Match won by…" and the scores Black Misconduct during an interval is dealt with immediately, as if during a game. Misconduct on the field of play before "Play" is first called gets a card that doesn't change the score but counts towards later offences. Misconduct after the match on the field of play is carded and reported. Offences include deliberately delaying play, damaging the shuttle, offensive or inappropriate behaviour, and a player's phone or electronic device ringing or being used for communication on court. Record and report every incident and the action taken to the referee.
