Decide whether or not a match shall be begun or stopped owing to the state of the courts, the state of the weather, darkness, or other unavoidable hindrance, and, having been postponed or stopped, whether play shall begin or continue. During the course of a Tie decide whether or not a match can be transferred indoors and/or to another surface in case of bad weather. Instruct a Chair Umpire to enforce the Code of Conduct should any disturbance or interference by spectators or others occur. Ensure that all members of the team, including the Captain, comply with the section of the Fed Cup Code of Conduct dealing with dress and equipment, including Team Identification. Ensure that when substitutions are sanctioned for reasons of health, a medical certificate from the independent doctor is presented. Change the decision of a Line Umpire or Chair Umpire, or order a point to be replayed, when a very clearly incorrect call or decision has been made relating to a Question of Fact. However, the Referee only has this authority when there is a non-neutral Chair Umpire officiating the match and the Referee is sitting on court. Note: The Referee should always remember that the intention is to give him/her the power to correct very clear mistakes, and not to become a second Chair Umpire. Immediately on the completion of a Tie submit a Referee's Report to the ITF for distribution to the two Associations concerned. Ensure, in addition to on court officials, that only the nominated teams shall be present for the presentation and, in the case of the Final, the closing ceremony on court.

(b) The Referee shall have the power to give a formal warning to a Captain and, after two warnings, may remove him/her from the match in course and/or for the following matches of that Tie, in which case the Captain may be replaced only by a member of the nominated team. The Referee may also remove the Captain without a formal warning for a single incident of misconduct. The Captain shall be allowed to sit on the court beside the chair of his/her team but he/she may not move away from that area. Apart from his/her team, he/she may talk to the Chair Umpire and to the Referee. He/she may not talk to any Line Umpires. 22
