Code for Umpires

I will officiate by the rules.

I will ensure that I am knowledgeable of the rules.

I will control my temper.  Personal criticism of any person by word or gesture is unacceptable.

I will show respect for the participants and their skills.

I will refrain from profanity. Verbal abuse towards players, managers, coaches, officials or spectators will not be tolerated including emails, voice messages, text messages (as well as “tweeting”) and social network postings.

I will not allow use of tobacco, alcohol or drugs (unless prescribed by a licensed physician) on the field or in the dug out or in the vicinity thereof.

I will be friendly to all participants and encourage players to ask me to clarify any call, whether it is a judgement call or a decision on the Rules.

I will generally warn players of unacceptable behaviour before taking further action for a second offence, although I reserve the right to cite or eject a player for a first offence.
