Glyn Schofield will appeal a suspension and fine for weighing in light after a race at Rosehill on Saturday which has prompted NSW stewards to push for a change to betting rules.

The jockey was handed a six-meeting ban and $2000 fine and Wouldnt It be Nice was disqualified from his third placing in the two-year-old race.

Racing NSW chief steward Ray Murrihy said while the horse must be disqualified, he would address a national stewards' conference later this month on whether punters should have their investments refunded.

"I have put it up before but have not been successful," Murrihy said.

"There is a national stewards' conference at the end of this month and we will raise it again.

"We can't do anything about the horse being disqualified but we think there should be a way to get a refund for the punter."

Murrihy and Australian Turf Club officials also discussed fast-tracking the introduction of electronic scales to be used at Rosehill and Randwick and the club also indicated it would compensate connections of Wouldnt It Be Nice.

Schofield, who has ridden all round the world, agreed electronic scales were the way to go but could offer no explanation for what happened on Saturday.

He said he weighed himself in the jockeys' room before weighing out at 59.1kg in the presence of two clerks of scales but came back after the race at 58.3kg.

He pleaded guilty to the charge with the rules clear that liability rests with the jockey.

Although Schofield could not explain the weight differential, Murrihy said it was clear to stewards the mistake happened when he weighed out.

"There can only be one explanation on the evidence," he said.

"And that is that Glyn Schofield weighed out at the wrong weight.

"There was rain during the race and if anything, we would have expected him to come back heavier.

"There is no other explanation."
