The Chair  Umpire awards the point to the server, but the receiver disagrees  156 157 Decision:  The point stands as played. The Chair Umpire cannot  make assumptions as to the intent of player B’s comment. The  Case:  Player A serves and player B returns the ball for a winner.  Player A appeals to the Chair Umpire that the service was a let. The  Chair Umpire says that he did not hear a let. Player A then asks  player B if he heard a let. Player B answers yes. Upon hearing this,  the Chair Umpire says that since both players heard a let, we shall  play a let. Player B objects saying that it is the Chair Umpire’s call  and that he was only confirming to player A that the Chair Umpire  had made a mistake. Appealing for a Let Decision:  The point stands as played. When the Chair Umpire has  the primary responsibility for a call (nets, throughs, not-ups and  touches) as opposed to the secondary responsibility (line calls), an  immediate decision must be made. If the Chair Umpire did not see a  rules violation on something for which he has the primary responsi- bility then technically no violation can be called Case:  Player A stops play claiming that player B had played the  ball after it had bounced twice.
