Who decides questions of fact and questions of law: chair umpire, roving umpire or referee?

Question

Accepted Answer

Questions of fact (what actually happened): the chair umpire makes the final decision. A referee cannot be called to court to review whether a ball was out. Questions of law (applying the rules to specific facts): the chair umpire makes the first decision, and the players have the right to call the referee to court if they disagree. The referee's decision is final. The referee is the final authority on all questions of tennis law and the final on-site authority on the Tournament Regulations, Code of Conduct and Rules of Tennis. If a chair or roving umpire cannot decide a point of law, the referee does. Where the score of the match is in question, the umpire suspends play and brings it to the referee at once; in other cases play continues while an appeal is considered. Roving umpire: where one is appointed, their decision is final. Where a referee is also appointed, a player may appeal to the referee on a question of law and the referee's decision is final. No chair umpire: the roving umpire, assistant referee or referee can correct clear line call errors by players when watching the court directly. If neither a line umpire nor the chair can make a decision on a question of fact, the point is replayed.
