Match finished a tie. The ##### rules say
"Where no price is quoted for the tie and the official competition rules do not determine a winner then Dead-Heat rules will apply, in competitions where a bowl out or the toss of a coin determines a winner then bets will be settled on the official result. "
The Deat-heat rules are
"Where two selections Dead-Heat half the stake money is lost and the full odds are paid to the other half. "
What do you want to do Jeff?
If you follow that rule people who bet on Essex will end up losing a little, and those who bet on Leics would make a small profit.
Or you could just abandon the event and give everyone's money back?
