The FIH Rules Committee regularly reviews all the Rules of Hockey. It takes account of information and observations from a wide variety of sources including National Hockey Associations, players, coaches, officials, media and spectators together with match and competition reports, video analysis, Rules trials and Tournament Regulations which vary the Rules. Ideas which have already been trialled with the FIH Rules Committee’s approval in local or limited circumstances are especially valuable. Rules changes can then be based on practical experience. It is the intention of the Rules and Competitions Committees to try and reduce as far as possible the number of variations to the Rules which occur through Tournament Regulations. These differences have led in the past to some confusion on the part of players, officials, spectators and television audiences.
