SQUASH – SINGLES RULES
The definition of words in italics may be found in Appendix 1.
INTRODUCTION
Squash is played in a confined space, often at a high speed. Two principles are essential for orderly
play:
Safety: Players must always place safety first and not take any action that could endanger the
opponent.
Fair play: Players must respect the rights of the opponent and play with honesty.
1 THE GAME
1.1. Singles Squash is played in a court between two players, each holding a racket to
strike the ball. The court, ball, and racket must meet WSF specifications (see
Appendices 7, 8 and 9).
1.2. Each rally starts with a serve, and the players then return the ball alternately until the
rally ends (see Rule 6: The Play).
1.3. Play must be continuous as far as is practical.
2 SCORING
2.1 The winner of a rally scores 1 point and serves to begin the next rally.
2.2 Each game is played to 11 points, except that if the score reaches 10-all, the game
continues until one player leads by 2 points.
2.3 A match is normally the best of 5 games, but may be the best of 3 games.
2.4 Alternative scoring systems are described in Appendix 3.
3 OFFICIALS
3.1 A match should normally be officiated by a Marker and a Referee, both of whom must
keep a record of the score, which player is serving, and the correct box for service.
3.2 If there is only one Official, that Official is both the Marker and the Referee. A player
may appeal any call or lack of call made by that Official as Marker to that same Official
as the Referee.
3.3 The correct position for the Officials is seated at the centre of the back wall, as close
to that wall as possible and just above the out-line.
3.4 An alternative Officiating System called the 3-Referee System is described in Appendix
4.
3.5 When addressing players, Officials must use the family name, where possible.
3.6 The Marker:
3.6.1 must announce the match, introduce each game, and announce the result
of each game and of the match (see Appendix 2);
3.6.2 must call “fault ,” “down ,” “out ,” “not up ” or “stop”, as appropriate;
3.6.3 must make no call, if unsure about a serve or return;
3.6.4 must call the score without delay at the end of a rally, with the server’s
score first, preceded by “hand out ” when there is a change of server;
3.6.5 must repeat the Referee’s decision after a player’s request for a let, and
then call the score;
3.6.6 must wait for the Referee’s decision after a player’s appeal against a
Marker’s call or lack of a call, and then call the score;
2 | P a g e
3.6.7 must call “Game Ball” when a player needs 1 point to win a game, or “Match
Ball” when a player needs 1 point to win the match;
3.6.8 must call “10-all: a player must win by 2 points” when the score reaches
10-all for the first time in a match.
3.7 The Referee, whose decision is final:
3.7.1 must postpone the match if the court is not satisfactory for play; or suspend
play if the match is already in progress, and when the match resumes later,
allow the score to stand;
3.7.2 must allow a let if through no fault of either player a change of court
conditions affects a rally;
3.7.3 may award the match to a player whose opponent is not on court ready to
play within the time stated in the competition rules;
3.7.4 must rule on all matters, including all requests for a let and all appeals
against a Marker’s call or lack of a call;
3.7.5 must rule immediately if disagreeing with the Marker’s call or lack of a call,
stopping play if necessary;
3.7.6 must correct the score immediately if the Marker announces the score
incorrectly, stopping play if necessary;
3.7.7 must enforce all the Rules relating to time, announcing “15 seconds,” “Halftime”
and “Time,” as appropriate;
Note: It is the players’ responsibility to be close enough to hear these
announcements.
3.7.8 must make the appropriate decision if the ball hits either player (see Rule
9: Ball Hitting A Player);
3.7.9 may allow a let if unable to decide an appeal against a Marker’s call or lack
of call;
3.7.10 must ask the player for clarification if uncertain about the reason for a
request for a let or an appeal ;
3.7.11 may give an explanation for a decision;
3.7.12 must announce all decisions in a voice loud enough to be heard by the
players, the Marker and the spectators;
3.7.13 must apply Rule 15 (Conduct) if a player’s conduct is unacceptable;
3.7.14 must suspend play if the behaviour of any person, other than a player, is
disruptive or offensive, until the behaviour has ceased, or until the
offending person has left the court area.
4 THE WARM-UP
4.1 At the start of a match the players go on court together to warm up the ball for a
maximum of 4 minutes. After 2 minutes the players must change sides, unless they
have already done so.
4.2 The players must have equal opportunities to strike the ball. A player retaining control
of the ball for an unreasonable time is warming up unfairly and Rule 15 (Conduct)
must be applied.
5 THE SERVE
5.1 The player who wins the spin of a racket serves first.
5.2 At the beginning of each game and after each change of server, the server chooses
from which service-box to serve. While retaining the serve, the server must serve
from alternate boxes.
5.3 If a rally ends in a let, the server must serve again from the same box.
5.4 If the server moves to the wrong box to serve, or if either player is unsure of the
correct box, the Marker must inform the players which is the correct box.
3 | P a g e
5.5 If there is any dispute about the correct box, the Referee must rule.
5.6 After the Marker has called the score, both players must resume play without
unnecessary delay. However, the server must not serve before the receiver is ready.
5.7 A serve is good, if:
5.7.1 the server drops or throws the ball from a hand or racket and strikes it
correctly on a first or further attempt before it touches anything else; and
5.7.2 at the time the server strikes the ball, one foot is in contact with the floor
inside the service-box with no part of that foot touching any boundary of
that box; and
5.7.3 the ball is struck directly to the front wall, hitting it between the serviceline
and the out-line, but does not hit the front and side walls at the same
time; and
5.7.4 the ball, unless volleyed by the receiver, bounces for the first time in the
opposite quarter-court without touching any line; and
5.7.5 the ball is not served out .
5.8 A serve that does not comply with Rule 5.7 is a fault and the receiver wins the rally.
Note: A serve that hits the service-line, or the short-line, or the half-court line, or any
line bounding the top of the court, is a fault.
5.9 If the server drops or throws the ball, but makes no attempt to strike it, this is not a
serve, and the server may start again.
5.10 A let is allowed if the receiver is not ready to return the serve and does not attempt
to do so. However, if that serve is a fault, the server loses the rally.
5.11 If the server serves from the wrong service-box, and the server wins the rally, the
rally stands and the server then serves from the alternate box.
5.12 The server must not serve until the score has been called by the Marker, who must
do so without delay. In such an event, the Referee must stop play and instruct the
server to wait until the score has been called.
6 THE PLAY
6.1 If the serve is good, play continues as long as each return is good, or until a player
requests a let or makes an appeal , or one of the Officials makes a call, or the ball hits
either player or their clothing or the non-striker’s racket.
6.2 A return is good if the ball:
6.2.1 is struck correctly before it has bounced twice on the floor; and
6.2.2 without hitting either player, or their clothing or racket, hits the front wall,
either directly or after hitting any other wall(s), above the tin and below
the out-line, without having first bounced on the floor; and
6.2.3 rebounds from the front wall without touching the tin; and
6.2.4 is not out .
7 INTERVALS
7.1 A maximum of 90 seconds is permitted between the end of the warm-up and the start
of play, and between each game.
7.2 Players must be ready to resume play at the end of any interval, but play may resume
earlier if both agree.
7.3 A maximum of 90 seconds is permitted to change damaged equipment. This includes
glasses, protective eye-wear or a dislodged contact lens. The player must complete
the change as quickly as possible, or Rule 15 (Conduct) must be applied.
7.4 Intervals in the case of injury or bleeding are specified in Rule 14 (Injury).
7.5 During any interval either player may strike the ball.
4 | P a g e
8 INTERFERENCE
8.1 After completing a reasonable follow-through, a player must make every effort to
clear, so that when the ball rebounds from the front wall the opponent has:
8.1.1 a fair view of the ball on its rebound from the front wall; and
8.1.2 unobstructed direct access to the ball; and
8.1.3 the space to make a reasonable swing at the ball; and
8.1.4 the freedom to strike the ball to any part of the front wall.
Interference occurs when the player does not provide the opponent with all of these
requirements.
8.2 A striker who believes that interference has occurred may stop and request a let,
preferably by saying “Let, please.” That request must be made without undue delay.
Notes:
 Before accepting any form of request the Referee must be satisfied that the player
is actually requesting a let.
 A request for a let includes a request for a stroke.
 Normally, only the striker may request a let for interference. However, if the nonstriker
requests a let for lack of access before the ball has reached the front wall,
that request may be considered, even though that player is not yet the striker.
8.3 The Referee, if uncertain about the reason for a request, must ask the player for an
explanation.
8.4 The Referee may allow a let or award a stroke without a request having been made,
stopping play if necessary, especially for reasons of safety.
8.5 If the striker strikes the ball and the opponent then requests a let, but then the ball
goes down or out , the opponent wins the rally.
8.6 General
The following provisions apply to all forms of interference:
8.6.1 if there was neither interference nor reasonable fear of injury, no let is
allowed;
8.6.2 if there was interference but the striker would not have been able to make
a good return , no let is allowed;
8.6.3 if the striker continued play beyond the interference and then requested a
let, no let is allowed;
8.6.4 if there was interference, but it did not prevent the striker from seeing and
getting to the ball to make a good return , this is minimal interference and
no let is allowed;
8.6.5 if the striker would have been able to make a good return but the opponent
was not making every effort to avoid the interference, a stroke is awarded
to the striker;
8.6.6 if there was interference that the opponent was making every effort to
avoid and the striker would have been able to make a good return , a let is
allowed;
8.6.7 if there was interference and the striker would have made a winning return ,
a stroke is awarded to the striker.
In addition to Rule 8.6, the following provisions apply to specific situations.
8.7 Fair View
Fair View means enough time to view the ball and prepare to strike it as it returns
from the front wall.
8.7.1 If the striker requests a let for lack of fair view of the ball on its return from
the front wall, the provisions of 8.6 apply.
8.8 Direct Access
If the striker requests a let for lack of direct access to the ball, then:
5 | P a g e
8.8.1 if there was interference but the striker did not make every effort to get to
and play the ball, no let is allowed;
Note:
Every effort to get to and play the ball should not include contact with the opponent.
If any contact that could have been avoided is made, Rule 15 (Conduct) must be
applied.
8.8.2 if the striker had direct access but instead took an indirect path to the ball
and then requested a let for interference, no let is allowed, unless Rule
8.8.3 applies;
8.8.3 if the striker was wrong-footed , but showed the ability to recover and make
a good return , and then encountered interference, a let is allowed, unless
the striker would have made a winning return , in which case a stroke is
awarded to the striker.
8.9 Racket Swing
A reasonable swing comprises a reasonable backswing, a strike at the ball and a
reasonable follow-through. The striker’s backswing and follow-through are reasonable
as long as they do not extend more than is necessary.
If the striker requests a let for interference to the swing, then:
8.9.1 if the swing was affected by slight contact with the opponent who was
making every effort to avoid the interference a let is allowed, unless the
striker would have made a winning return , in which case a stroke is
awarded to the striker;
8.9.2 if the swing was prevented by contact with the opponent, a stroke is
awarded to the striker, even if the opponent was making every effort to
avoid the interference;
8.9.3 where there has been no actual contact and the swing has been held by
the striker for fear of hitting the opponent, the provisions of 8.6 apply.
8.10 Excessive Swing
8.10.1 If the striker caused the interference by using an excessive swing, no let is
allowed.
8.10.2 If there was interference but the striker exaggerated the swing in
attempting to earn a stroke, a let is allowed.
8.10.3 The striker’s excessive swing can contribute to interference for the
opponent when it becomes the latter’s turn to play the ball, in which case
the opponent may request a let.
8.11 Freedom to strike the ball to any part of the front wall
If the striker refrains from striking the ball because of front-wall interference, and
requests a let, then:
8.11.1 if there was interference and the ball would have hit the non-striker on a
direct path to the front wall, a stroke is awarded to the striker, unless the
striker had turned or was making a further attempt , in which case a let is
allowed;
8.11.2 if the ball would first have hit the non-striker and then a side wall before
reaching the front wall, a let is allowed, unless the return would have been
a winning return , in which case a stroke is awarded to the striker; or
8.11.3 if the ball would first have hit a side wall and then the non-striker before
reaching the front wall, a let is allowed unless the return would have been
a winning return , in which case a stroke is awarded to the striker.
8.12 Further Attempt.
If the striker requests a let for interference while making a further attempt to strike
the ball, and could have made a good return , then:
8.12.1 if the non-striker had no time to avoid the interference, a let is allowed.
6 | P a g e
8.13 Turning
Turning is the action of the player who strikes, or is in a position to strike, the ball to
the right of the body after the ball has passed behind it to the left or vice versa,
whether the player physically turns or not.
If the striker encounters interference while turning , and could have made a good
return , then:
8.13.1 if the swing was prevented, even though the opponent was making every
effort to avoid the interference, a stroke is awarded to the striker;
8.13.2 if the non-striker had no time to avoid the interference, a let is allowed;
8.13.3 if the striker could have struck the ball without turning , but turned in order
to create an opportunity to request a let, no let is allowed.
8.13.4 When the striker turns, the Referee must always consider whether the
action was dangerous and rule accordingly.
9 BALL HITTING A PLAYER
9.1 If the ball, on its way to the front wall, hits the non-striker or the non-striker’s
racket or clothing, play must stop; then:
9.1.1 if the return would not have been good, the non-striker wins the rally;
9.1.2 if the return was going directly to the front wall, and if the striker was
making a first attempt without having turned , a stroke is awarded to the
striker;
9.1.3 if the ball had hit or would have hit any other wall before the front wall and
the striker had not turned , a let is allowed, unless the return would have
been a winning return , in which case a stroke is awarded to the striker;
9.1.4 if the striker had not turned but was making a further attempt , a let is
allowed;
9.1.5 if the striker had turned , a stroke is awarded to the non-striker, unless the
non-striker made a deliberate movement to intercept the ball, in which
case, a stroke is awarded to the striker.
9.2 If the ball, on its return from the front wall, hits a player before bouncing twice on
the floor, play must stop; then:
9.2.1 if the ball hits the non-striker or the non-striker’s racket, before the striker
has made an attempt to strike the ball and no interference has occurred,
the striker wins the rally, unless the striker’s position has caused the nonstriker
to be hit, in which case a let is allowed;
9.2.2 if the ball hits the non-striker, or the non-striker’s racket, after the striker
has made one or more attempts to strike the ball, a let is allowed, providing
the striker could have made a good return . Otherwise, the non-striker wins
the rally;
9.2.3 if the ball hits the striker and there is no interference, the non-striker wins
the rally. If interference has occurred, Rule 8 (Interference) applies.
9.3 If the striker hits the non-striker with the ball, the Referee must consider if the action
was dangerous and rule accordingly.
10 APPEALS
10.1 Either player may stop play during the rally and appeal against any lack of call by the
Marker by saying “Appeal, please.”
10.2 The loser of a rally may appeal against any call or lack of a call by the Marker by
saying “Appeal, please.”
10.3 If the Referee is uncertain which return is being appealed, the Referee must ask for
clarification. If there is more than one appeal, the Referee must consider each one.
7 | P a g e
10.4 After the ball has been served, neither player may appeal anything that occurred
before that serve, with the exception of a broken ball.
10.5 At the end of a game any appeal regarding the last rally must be immediate.
10.6 In response to an appeal against a Marker’s call or lack of call the Referee must:
10.6.1 if the Marker’s call or lack of call was correct, allow the result of the rally to
stand; or
10.6.2 if the Marker’s call was incorrect, allow a let, unless the Marker’s call
interrupted a winning return by either player, in which case award the rally
to that player; or
10.6.3 if the Marker made no call on a serve or return that was not good, award
the rally to the other player; or
10.6.4 if the Referee was uncertain whether the serve was good, allow a let; or
10.6.5 if the Referee was uncertain whether the return was good, allow a let,
unless the Marker’s call interrupted a winning return by the other player, in
which case award the rally to that player.
10.7 In all cases the Referee’s decision is final.
11 THE BALL
11.1 If the ball breaks during a rally, a let is allowed for that rally.
11.2 If a player stops play to appeal that the ball is broken, and it is found that the ball is
not broken, that player loses the rally.
11.3 If the receiver, before attempting to return serve, appeals that the ball is broken, and
the ball is found to be broken, the Referee, if uncertain when it broke, must allow a
let for the previous rally.
11.4 A player who wishes to appeal at the end of a game that the ball is broken must do
so immediately and before leaving the court.
11.5 The ball must be changed if both players agree or if the Referee agrees with one
player’s request.
11.6 If a ball has been replaced, or if the players resume the match after a delay, the
players may warm up the ball. Play resumes when both players agree or at the
discretion of the Referee, whichever is sooner.
11.7 The ball must remain in the court at all times, unless the Referee permits its removal.
11.8 If the ball becomes wedged in any part of the court, a let is allowed.
11.9 A let may be allowed if the ball touches any article in the court.
11.10 No let is allowed for any unusual bounce.
12 DISTRACTION
12.1 Either player may request a let because of distraction, but must do so immediately.
12.2 If the distraction was caused by one of the players, then:
12.2.1 if accidental, a let is allowed, unless a player’s winning return was
interrupted, in which case the rally is awarded to that player;
12.2.2 if deliberate, Rule 15 (Conduct) must be applied.
12.3 If the distraction was not caused by one of the players, a let is allowed, unless a
player’s winning return was interrupted, in which case the rally is awarded to that
player.
12.4 At some events crowd reactions during play may occur. To encourage spectator
enjoyment, Rule 12.3 may be suspended, and if sudden crowd noise occurs, players
will be expected to continue play and referees will not ask spectators to be quiet.
However, a player who stops play and requests a let because of a loud or isolated
noise from off the court may be allowed a let for distraction.
8 | P a g e
13 FALLEN OBJECT
13.1 A player who drops a racket may pick it up and play on, unless the ball touches the
racket, or distraction occurs, or the Referee applies a Conduct Penalty.
13.2 A striker who drops the racket because of interference may request a let.
13.3 A non-striker who drops the racket because of contact during the striker’s effort to
reach the ball may request a let, and Rule 12 (Distraction) applies.
13.4 If any object, other than a player’s racket, falls to the floor during a rally, play must
stop; then:
13.4.1 if the object fell from a player without any contact with the opponent, the
opponent wins the rally;
13.4.2 if the object fell from a player because of contact with the opponent, a let
is allowed, unless the striker has struck a winning return , or requests a let
for interference, in which case Rule 8 (Interference) is applied;
13.4.3 if the object falls from a source other than a player, a let is allowed, unless;
13.4.4 the striker’s winning return was interrupted, in which case the rally is
awarded to the striker;
13.4.5 if the object was not seen until the rally ended and had no effect on the
outcome of the rally, the result of the rally stands.
14 ILLNESS, INJURY AND BLEEDING
14.1 Illness
14.1.1 A player who suffers an illness that involves neither an injury nor bleeding
must either continue play immediately, or concede the game in progress
and take the 90-second interval between games to recover. This includes
conditions such as a cramp, nausea, and breathlessness, as well as asthma.
Only 1 game may be conceded. The player must then resume play, or
concede the match.
14.1.2 If a player’s vomiting or other action causes the court to become
unplayable, the match is awarded to the opponent.
14.2 Injury
The Referee:

interval between games, or concede the match. Only 1 game may be
conceded.
Note: A player who concedes a game retains any points already scored.
14.3 Categories of injury:

resume play, must concede that game and take the 90-second interval
between games for further recovery. Only 1 game may be conceded. The
player must then resume play or concede the match.
9 | P a g e
14.3.2 Contributed: where the injury is the result of accidental action by both
players.
The injured player is permitted 15 minutes to recover. This may be
extended by a further 15 minutes at the discretion of the Referee. If the
player is then unable to continue, the match is awarded to the opponent.
The score at the conclusion of the rally in which the injury occurred, stands.
14.3.3 Opponent-inflicted: where the injury is caused solely by the opponent.
14.3.3.1 Where the injury is accidentally caused by the opponent, Rule

possible, the wound has been covered.
14.4.2 If the bleeding was accidentally caused by the opponent, then Rule 15
(Conduct) must be applied.
14.4.3 If the bleeding is the result of the opponent’s deliberate or dangerous
play or action, the match is awarded to the injured player.
14.4.4 A player who is unable to stop the bleeding within the time permitted must
either concede 1 game and take the 90-second interval and then continue
play, or concede the match.
14.4.5 If blood is again visible during play, no further recovery time is permitted,
and the player must concede the game in progress and use the 90-second
interval between games for further treatment. If the bleeding has not then
stopped, the player must concede the match.

APPENDIX 1 – DEFINITIONS
APPEAL A player’s request to the Referee to review a Marker’s call or lack of a call,
or to appeal that the ball is broken.
ATTEMPT Any forward movement of the racket towards the ball. A fake swing is also
an attempt, but racket preparation with only a backswing and no forward
movement towards the ball is not an attempt.
BOX, SERVICE-BOX A square area on each side of the court bounded by the short-line, a side
wall and by 2 other lines, from where the server serves.
CORRECTLY When the ball is struck with the racket, held in the hand, not more than once,
and without prolonged contact on the racket.
DOWN A return that hits the tin or the floor before reaching the front wall, or hits
the front wall and then the tin.
FAIR VIEW Enough time to view the ball and prepare to strike it as it returns from the
front wall.
FAULT A serve that is not good.
FURTHER ATTEMPT A subsequent attempt by the striker to serve or return a ball that is still in
play, after having already made one or more attempts.
GAME A part of a match. A player must win 3 games to win a best of 5-game match
and 2 games to win a best of 3-game match.
GOOD RETURN A return that is struck correctly and that travels to the front wall either
directly or after hitting another wall or walls without going out, and that hits
the front wall above the tin and below the out-line.
HAND OUT A change of server.
LET The result of a rally that neither player wins. The server serves again from
the same box.
MATCH The complete contest, including the warm-up.
NOT UP A return that:
a player does not strike correctly; or
bounces more than once on the floor before being struck; or
touches the striker or the striker’s clothing.
OUT A return that:
hits the wall on or above the out-line; or
hits any fixture above the out-line; or
hits the top edge of any wall of the court; or
passes over a wall and out of the court; or
passes through any fixture.
QUARTER-COURT One of two equal parts of the court bounded by the short-line, a side wall,
the back wall and the half-court line.
RALLY A good serve followed by one or more alternate returns until one player fails
to make a good return.
SERVICE-BOX See BOX, SERVICE-BOX.
STRIKER A player is the striker from the moment the opponent’s return rebounds from
the front wall until the player’s return hits the front wall.
TIN The area of the front wall covering the full width of the court and extending
from the floor up to and including the lowest horizontal line.
TURNING The action of the striker who strikes, or is in a position to strike, the ball to
the right of the body after the ball has passed behind it to the left or vice
versa, whether the striker physically turns or not.
Note: Shaping (preparing) to play the ball on one side and then bringing the
racket across the body to strike the ball on the other side is neither turning
nor making a further attempt.
WINNING RETURN A good return that the opponent could not reach.
WRONG-FOOTED The situation when a player, anticipating the path of the ball, moves in one
direction, while the striker strikes the ball in another direction.

APPENDIX 3 – ALTERNATIVE SCORING SYSTEMS
1. Point-a-rally scoring to 15
Rule 2 (Scoring) is replaced by (see italics):
2.1 The winner of a rally scores 1 point and serves to begin the next rally.
2.2 Each game is played to 15 points, except that if the score reaches 14-all, the game continues
until one player leads by 2 points.
2.3 A match is normally the best of 5 games, but may be the best of 3.
2. Hand-in/hand-out scoring
Rule 2 (Scoring) is replaced by (see italics):
2.1 The server, on winning a rally, scores a point; the receiver, on winning a rally, becomes the
server without a change of score.
2.2 Each game is played to 9 points, except that if the score reaches 8-all, the receiver chooses,
before the next service, to continue that game either to 9 (known as “Set 1”) or to 10 (known
as “Set 2”). The receiver must clearly indicate this choice to the Marker, Referee and the
opponent.
2.3 A match is normally the best of 5 games, but may be the best of 3.
15 | P a g e
APPENDIX 4 – THE THREE-REFEREE SYSTEM
1. The Three-Referee System uses a Central Referee (CR) and two Side Referees (SRs) who must
work together as a team. All should be the highest accredited referees available. If the 3
Officials are not of a similar standard, then the Referee of the highest standard should normally
act as the CR.
2. The CR, who is also the Marker, controls the match and must consult with the SRs before the
match and if necessary (and if possible) between games, to try and ensure consistency of
rules application and interpretation. One of the SRs keeps score as a backup. In the event of
a discrepancy the CR’s score is final.
3. The two SRs should be seated behind the back wall in line with the inside line of the service
box on each side, one row in front of the CR.
4. The SRs make decisions at the end of rallies – not during them – on the following matters
only:
4.1 When a player requests a let; or appeals against a call or lack of a call of down, not up,
out, or fault by the CR.
4.2 If any Referee is unsighted that Referee’s decision is “Yes, Let.”
4.3 If the CR is unsure of the reason for an appeal, the CR must ask the player for
clarification.
4.4 If a SR is unsure of what is being appealed, the SR must ask the CR for clarification.
5. Only the CR decides all other matters including time-periods, conduct, injury, distraction,
broken ball, fallen object, and court conditions, none of which may be appealed.
6. Every appeal must be decided by all 3 Referees, simultaneously and independently.
7. A majority decision of the 3 referees is final, unless a video referee system is in operation.
8. The decision of the 3 Referees must be announced by the CR without revealing the individual
decisions.
9. In the case of 3 different decisions (Yes Let, No Let, Stroke), the final decision will be “Yes,
Let.”
10. Players may speak only to the CR. Dialogue must be kept to a minimum.
11. The Referees may give their decisions using (in order of preference):
1. Electronic consoles; or
2. Referee Decision Cards; or
3. Hand signals.
12. If hand signals are used:
Yes, Let = Thumb and forefinger in the shape of an ‘L’.
Stroke = Clenched fist.
No Let = Hand held out flat, palm downwards.
Ball was Down / Not Up / Out / Fault = Thumb Down.
Ball was Good = Thumb Up.
16 | P a g e
APPENDIX 5 – VIDEO REVIEW
May be used where the technology is available.
RULES/PROCEDURE
1. A player may request a review of an Interference decision of Let, Stroke or No Let only, but
may not appeal any Marker calls. Each player has one review per game; if the original decision
is overruled, the player retains the review.
2. The player must clearly and immediately ask the Central Referee (CR) for a “Video Review,
please.”
3. The CR then states: “Video review, please, (player’s name), on the Yes, Let/No Let/Stroke
decision.”
4. The replays will be shown on the screens.
5. The decision of the Video Review Official, whose decision is final, will be displayed on the
screens.
6. The CR then states either: “Yes, Let/No Let/Stroke decision upheld, (player’s name) has no
review remaining”; or “Yes, Let/No Let/Stroke decision overruled, (player’s name) has 1 review
remaining.”
7. When the score reaches 10-all, each player will have only 1 further review available. Unused
reviews may not be carried over beyond the score of 10-all or into any following games. The
CR announces: “10-all, a player must win by 2 points. Each player has 1 review available.”
8. If a video review is unavailable because of technical difficulties, this will not count as a review
being used.
APPENDIX 6 – PROTECTIVE EYEWEAR
The WSF recommends that all squash players should wear protective eyewear, manufactured to an
appropriate National Standard, properly over the eyes at all times during play, including the warmup.
Current National Standards for Racket Sport Eye Protection are published by the Canadian
Standards Association, the United States ASTM, Standards Australia/New Zealand and British
Standards Institution. It is the responsibility of the player to ensure that the quality of the product
worn is appropriate for the purpose.
Protective eyewear, meeting any of the above standards (or equivalent), is mandatory for all doubles
and junior events sanctioned by the WSF.
