Re: UMPIRING

Umpires must be in full uniform with a Yellow shirt and black short/skirt/pants and SHOES.

If you do  not sign the card properly you may not get paid.

Make sure match details including score and results are recorded.

Local Rules will continue in regards to umpires not showing. If it's an individual named who does not turn up -  a YELLOW card is given and their Team receives a loss of points.
