10. What is the use of a "briefing" for players and umpires?
International umpires may be briefed at major events by the Umpires Manager and / or the Tournament Director. This is to ensure consistency in the team of umpires. Similar advice is included in the Rules Book to reach a wider audience of players and umpires so that there is consistency within a National Association’s own domestic matches.
Many National Associations hold pre-season seminars to brief players and umpires about changes in the rules and interpretations and more generally to encourage a wide and consistent understanding of the rules.
All this activity is aiming to achieve a common understanding of the rules and their application.
