11. A goal may be scored from a free kick which is awarded because of any infringement of Law 9, but not from any other free kick.
12. A player shall not wear any nails, except such as have their heads driven in flush with the leather, or metal plates, or projections, or gutta percha on his boots, or on his shin guards. If bars or studs on the soles or heels of the boot are used they shall not project more than half an inch, and shall have all their fastenings driven in flush with the leather. Bars shall be transverse and flat, not less than half an inch in width, and shall extend from side to side of the boot. Studs shall be round in plan, not less than half an inch in diameter, and in no case conical or pointed[C]. Any player discovered infringing this law shall be prohibited from taking further part in the match. The referee shall, if required, examine the players' boots before the commencement of a match.
[C] (Wearing soft india rubber on the soles of boots is not a violation of this law.)
13. A referee shall be appointed, whose duties shall be to enforce the laws and decide all disputed points; and his decision on points of fact connected with the game shall be final. He shall also keep a record of the game and act as timekeeper. In the event of any ungentlemanly play on the part of the players the offender, or offenders, shall be cautioned, and if further offence is committed, or in case of violent conduct, without any previous caution the referee shall have power to order the offending player off the field of play, and shall transmit the name or names of such player or players to his or their National Association, who shall deal with the matter. The referee shall have power to allow for time wasted, to suspend the game when he thinks fit, and to terminate the game whenever by reason of darkness, interference by spectators, or other cause he may deem necessary. But in all cases in which a game is terminated he shall report the same to the Association under whose jurisdiction the game was played, who shall have full power to deal with the matter. The referee shall have power to award a free kick in any case in which he thinks the conduct of a player dangerous, but not sufficiently so as to justify him in putting in force the greater powers vested in him. The power of the referee extends to offences committed when the play has been temporarily suspended and when the ball is out of play.
(Persistent infringement of any of the laws of the game is ungentlemanly conduct within the meaning of this law. All reports by referees to be made within three days after the occurrence (Sundays not included), and reports will be deemed to be made when received in the ordinary course of post.)
14. Two linesmen shall be appointed, whose duty (subject to the decision of the referee) shall be to decide when the ball is out of play, and which side is entitled to the corner kick, goal kick, or throw-in; and to assist the referee in carrying out the game in accordance with the laws[D]. In the event of any undue interference or improper conduct by a linesman the referee shall have power to order him off the field of play and appoint a substitute, and report the circumstances to the National Association having jurisdiction over him, who shall deal with the matter.
[D] (Linesmen where neutral should call the attention of the referee to rough or ungentlemanly conduct, and generally assist him to carry out the game in a proper manner.)
15. In the event of a supposed infringement of the laws the ball shall be in play until a decision has been given.
16. In the event of any temporary suspension of play from any cause, the ball not having gone into touch or behind the goal line, the referee shall throw it down where it was when play was suspended, and the ball shall be in play when it has touched the ground. If the ball goes into touch or behind the goal line before it is played by a player, the referee shall again throw it down. The players on either side shall not play the ball until it has touched the ground.
17. In the event of any infringement of Laws 5, 6, 8, 10, or 16, or of a player being sent off the field under Law 13, a free kick shall be awarded to the opposite side from the place where the infringement occurred. In the event of any intentional infringement of Law 9 outside the penalty area or by the attacking side within the penalty area, a free kick shall be awarded to the opposite side from the place where the infringement occurred. In the event of any intentional infringement of Law 9 by the defending side within the penalty area, the referee shall award the opponents a penalty kick[E], which shall be taken from the penalty kick mark under the following conditions:—
