In a correct Service.
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 the server's racket head, any delay in the start of the service, shall be considered to be an undue delay.
The server and receiver shall stand within diagonally opposite service courts without touching the boundary lines of these courts.
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 until the service is delivered.
Get your grade
The server's racket shall initially hit the base of the shuttle.
The whole shuttle shall be below the server's waist at the instant of being hit by the server's racket.
The shaft of the server's racket at the instant of hitting the shuttle shall be pointing in a downward direction.
The movement of the server's racket shall continue forwards from the start of the service until the service is delivered.
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, on or within the boundary lines.
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. Once started, the service is delivered when the shuttle is hit by the server's racket or, in attempting to serve, the server misses the shuttle. 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. In doubles, during the delivery of service, the partners may take up any positions within their respective courts, which do not unsight the opposing server or receiver.
The players shall serve from, and receive in, their respective right service courts when the server has not scored or has scored an even number of points in that game. The players shall serve from, and receive in, their respective left service courts when the server has scored an odd number of points in that game. If the server wins a rally, the server shall score a point. The server shall then serve again from the alternate service court. If the receiver wins a rally, the receiver shall score a point. The receiver shall then become the new server.
A player of the serving side shall serve from the right service court when the serving side has not scored or has scored an even number of points in that game. A player of the serving side shall serve from the left service court when the serving side has scored an odd number of points in that game. The player of the receiving side who served last shall stay in the same service court from where he served last. The reverse pattern shall apply to the receiver's partner. The player of the receiving side standing in the diagonally opposite service court to the server shall be the receiver. The players shall not change their respective service courts until they win a point when their side is serving. Service in any turn of serving shall be delivered from the service court corresponding to the serving side's score, except when a service court error has been made when a player has served or received out of turn or has served or received from the wrong service court. If a service court error is discovered, the error shall be corrected and the existing score shall stand.
For net play, clears, drop shots and smashes. It shall be a fault if.
If a service is not correct. If, in service, the shuttle is caught on the net and remains suspended on its top, after passing over the net, is caught in the net. Or is hit by the receiver's partner.
If in play, the shuttle lands outside the boundaries of the court (i.e. not on or within the boundary lines), passes through or under the net, fails to pass over the net, touches the ceiling or side walls, touches the person or dress of a player, touches any other object or person outside the court, is caught and held on the racket and then slung during the execution of a stroke, is hit twice in succession by the same player, is hit by a player and the player's partner successively, touches a player's racket and does not travel towards the opponent's court.
If, in play, a player touches the net or its supports with racket, person or dress, invades an opponent's court over the net with racket or person except that the striker
may follow the shuttle over the net with the racket in the course of a stroke after the initial point of contact with the shuttle is on the striker's side of the net, invades an opponent's court under the net with racket or person such that an opponent is obstructed or distracted. Obstructs an opponent, i.e. prevents an opponent from making a legal stroke where the
shuttle is followed over the net, deliberately distracts an opponent by any action such as shouting or making gestures, if a player is guilty of flagrant, repeated or persistent offence.
Ability to explain and implement appropriate safety
checks for equipment, clothing and playing area
and justification of their actions
Before the match, the umpire shall: obtain the score-sheet from the Referee, ensure that any scoring device to be used is working, see that the posts are on the doubles side lines, check the net for the height and ensure that there are no gaps between the ends of the
net and the net posts, ascertain whether there are any bye-laws regarding the shuttle hitting an obstruction ensure that the service judge and the line judges know their duties and that they are
correctly placed, ensure that a sufficient quantity of tested shuttles is readily available for the
match in order to avoid delays during play, check that the players' clothing conforms to the relevant Regulations concerning colour, designs, lettering and advertising, and ensure that any violations are rectified.
Any decision that the clothing was in violation of the regulations (or was nearly so) shall be advised to the referee or appropriate official before the match or, if this is not possible, immediately after the match. Carry out the toss fairly and ensure that the winning side and the losing side exercise their choices.
Court and court equipment.
The court shall be a rectangle marked out with lines 40 mm wide. The lines marking out the court shall be easily distinguishable and preferably be coloured white or yellow. All the lines shall form part of the area which they define. The posts shall be 1.55 metres in height from the surface of the court and shall remain vertical
when the net is strained. The posts or its supports shall not extend into the court. The posts shall be placed on the doubles side lines irrespective of whether singles or doubles is being played. The net shall be made of fine cord of dark colour and even thickness with a mesh of not less than l5 mm and not more than 20 mm The net shall be 760 mm in depth and at least 6.1 metres wide. The top of the net shall be edged with a 75 mm white tape doubled over a cord or cable running through the tape. This tape shall rest upon the cord or cable. The cord or cable shall be stretched firmly, flush with the top of the posts. The top of the net from the surface of the court shall be 1.524 metres at the centre of the court

and 1.55 metres over the side lines for doubles. There shall be no gaps between the ends of the net and the posts. If necessary, the full depth of the net at the ends shall be tied to the posts.
The shuttle shall be made of natural and/or synthetic materials. From whatever material the shuttle is made, the flight characteristics generally shall be similar to those produced by a natural feathered shuttle with a cork base covered by a thin layer of leather.
The shuttle shall have 16 feathers fixed in the base. The feathers shall have a uniform length between 62 mm to 70 mm when measured
from the tip to the top of the base.
The tips of the feathers shall lie on a circle with a diameter from 58 mm to 68 mm. The feathers shall be fastened firmly with thread or other suitable material.
The base shall be 25 mm to 28 mm in diameter and rounded on the bottom. The shuttle shall weigh from 4.74 to 5.50 grams.
The skirt, or simulation of feathers in synthetic materials, shall replace natural feathers. The base shall be as described above. Measurements and weight shall be as described above. However, because
of the difference in the specific gravity and other properties of synthetic materials in comparison with feathers, a variation of up to 10 per cent shall be acceptable.
Testing the shuttle for speed.
To test a shuttle, a player shall use a full underhand stroke which makes contact with the shuttle over the back boundary line. The shuttle shall be hit at an upward angle and in a direction parallel to the side lines.
A shuttle of correct speed will land not less than 530mm and not more than 990 mm short of the other back boundary line.
The racket shall be a frame not exceeding 680 mm in overall length and 230 mm in overall width. The handle is the part of the racket intended to be gripped by a player. The stringed area is the part of the racket with which it is intended that a player hits the shuttle. The head bounds the stringed area. The shaft connects the handle to the head. The throat (if present) connects the shaft to the head. The stringed area shall be flat and consist of a pattern of crossed strings either alternately interlaced or bonded where they cross. The stringing pattern shall be generally uniform and, in particular, not less dense in the centre than in any other area and shall not exceed 280 mm in overall length and 220 mm in overall width. However, the strings may extend into an area which otherwise would be the throat, provided that the width of the extended stringed area does not exceed 35 mm and the overall length of the stringed area does not then exceed 330 mm.
The International Badminton Federation shall rule on any question of whether any racket, shuttle or equipment or any prototype used in the playing of badminton complies with the specifications. Such
ruling may be undertaken on the Federation's initiative or on application by any party with a bona fide
interest, including any player, technical official, equipment manufacturer or Member Association or
