9.—The Committee shall help to keep order on the ground, and shall consult and decide upon any question arising out of the competition, if summoned for that purpose by the Referee or by any two of their number; and they shall have power, when so convened, the misconduct of a Competitor having been reported to them by a member of the Committee or an Umpire, to disqualify the offender, and further to order him off the ground, should his misconduct appear to them to justify such action, but before such action shall be taken, an opportunity of offering an explanation shall be afforded to the Competitor whose misconduct has been reported to them.
10.—It is the duty of an Umpire—
a. To ascertain that the net is at the right height before the commencement of play, and to measure and adjust the net during play, if asked to do so, or if, in his opinion, its height has altered;
b. To call the faults (subject to Regulation 11);
c. To call the strokes when won, or when he is asked to call them, and to record them on the Umpire's second sheet;[9]
d. To call the games and the sets at the end of each, or when asked to call them, and to record them on the Umpire's scoring sheet;
NOTE.—At the end of each game the games should be called with the name of the player who is in advance, thus: "2 games to 1, B. wins," or "B. leads." If the games are level the score should be called thus, "3 games all," or as the case may be. At the end of each set the sets should be called in like manner.
e. To direct the competitors to change sides, in accordance with Law 23;
f. When appealed to, during a rest, whether a doubtful ball is "in-play" or not, to call "Play it out," and at the conclusion of the rest, to give his decision (subject to Regulation 11) or direct the Competitors to play the stroke again;
