Badminton: Official Rules and Regulations (THE LAWS)

The Laws of Badminton
*For this Post I have placed different topics together.

TOSS:
6.1 Before play commences, a toss shall be conducted and the side winning the toss shall exercise the choice in either Law 6.1.1 or 6.1.2:

6.1.1 to serve or receive first;

6.1.2 to start play at one end of the court or the other.

6.2 The side losing the toss shall then exercise the remaining choice.


SCORING SYSTEM:
7.1 A match shall consist of the best of three games, unless otherwise arranged (Appendix 2 and 3).

7.2 A game shall be won by the side which first scores 21 points, except as provided in Law 7.4 and 7.5. 7.4

7.3 The side winning a rally shall add a point to its score. A side shall win a rally, if the opposing side commits a "fault" or the shuttle ceases to be in play because it touches the surface of the court inside the opponent's court.

7.4 If the score becomes 20-all, the side which gains a two point lead first, shall win that game.

7.5 If the score becomes 29-all, the side scoring the 30th point shall win that game.

7.6 The side winning a game shall serve first in the next game.


CHANGE OF ENDS:
8.1 Players shall change ends:

8.1.1 at the end of the first game;

8.1.2 at the end of the second game, if there is to be a third game; and

8.1.3 in the third game when a side first scores 11 points.

8.2 If the ends are not changed as indicated in Law 8.1, it shall be done so as soon as the mistake is discovered and when the shuttle is not in play. The existing score shall stand.


SERVICE:
9.1 In a correct service:

9.1.1 neither side shall cause undue delay to the delivery of the service once the server and the receiver are ready for the service. On completion of the backward movement of server's racket head, any delay in the start of the service (Law 9.2), shall be considered to be an undue delay.

9.1.2 the server and the receiver shall stand within diagonally opposite service courts (Diagram A) without touching the boundary lines of these service courts;

9.1.3 some part of both feet of the server and the receiver shall remain in contact with the surface of the court in a stationary position from the start of the service (Law 9.2) until the service is delivered (Law 9.3);

9.1.4 the server's racket shall initially hit the base of the shuttle;

9.1.5 the whole shuttle shall be below the server's waist at the instant of being hit by the server's racket. The waist shall be considered to be an imaginary line round the body, level with the lowest part of the server's bottom rib;

9.1.6 the shaft of the server's racket at the instant of hitting the shuttle shall be pointing in a downward direction;

9.1.7 the movement of the server's racket shall continue forwards from the start of the service (Law 9.2) until the service is delivered (Law 9.3)

9.1.8 the flight of the shuttle shall be upwards from the server's racket to pass over the net so that, if not intercepted, it shall land in the receiver's service court (i.e. on or within the boundary lines); and

9.1.9 in attempting to serve, the server shall not miss the shuttle.

9.2 Once the players are ready for the service, the first forward movement of the server's racket head shall be the start of the service.

9.3 Once started (Law 9.2), the service is delivered when the shuttle is hit by the server's racket or, in attempting to serve, the server misses the shuttle.

9.4 The server shall not serve before the receiver is ready. However, the receiver shall be considered to have been ready if a return of the service is attempted.

9.5 In doubles, during the delivery of service (Law 9.2, 9.3), the partners may take up any positions within their respective courts, which do not unsight the opposing server or receiver.
