Golf, for the most part, is played without a Rules official being present. However, the Committee in charge of a competition may appoint a referee and perhaps an observer, to accompany play, or it may assign Committee members to particular parts of the course to assist players with the Rules. It should go without saying that a Rules official must have a good knowledge of the Rules. This is considered to be more than just a playing knowledge.
A Rules official may spend all day on the course without being called upon to make a ruling. However, he must remain alert and be wary against becoming a “spectator” as a question may arise when least expected.
Therefore, a Rules official requires not only a good knowledge of the Rules, but an awareness of his duties and responsibilities and an appreciation of how best to handle various rules situations.
