3.—In matches where Umpires are appointed, their decision shall be final; but where a Referee is appointed, an appeal shall lie to him from the decision of an Umpire on a question of law.
4.—The choice of sides and the right of serving during the first games shall be decided by toss; provided that, if the winner of the toss choose the right to serve, the other player shall have the choice of sides, and vice-versâ; and provided that the winner of the toss may, if he prefer it, require the other player to make the first choice.
5.—The players shall stand on opposite sides of the net; the player who first delivers the ball shall be called the Server, the other the Striker-out.
6.—At the end of the first game the Striker-out shall become Server, and the Server shall become Striker-out; and so on alternately in the subsequent games of the set.
7.—The Server shall stand with one foot beyond (i.e., further from the net than) the base line, and with the other foot upon the base line, and shall deliver the service from the right and left Courts alternately, beginning from the right.
8.—The ball served must drop within the service-line, half-court-line, and side-line of the Court which is diagonally opposite to that from which it was served, or upon any such line.
9.—It is a fault if the service be delivered from the wrong Court, or if the Server do not stand as directed in Law 7, or if the ball served drop in the net or beyond the service-line, or if it drop out of Court or in the wrong Court; it is not a fault if the Server's foot, which is beyond the base-line, do not touch the ground at the moment at which the service is delivered.
10.—A fault may not be taken.
11.—After a fault, the Server shall serve again from the same Court from which he served that fault, unless it was a fault because served from the wrong Court.
