The move to have electronic scales at racecourses escalated after a horse was disqualified at Rosehill on Saturday when a jockey weighed in light.

Racing NSW stewards will also push for a rule change to allow punters to be refunded in the event of such a disqualification, similar to a late scratching rule being applied.

Glyn Schofield came back to scale at 58.3kg after weighing out for his ride on two-year-old Wouldn't It Be Nice at 59kg.

Schofield could offer no explanation for the discrepancy and stewards were forced to disqualify Wouldn't It Be Nice who had run third to Bull Point in the Forum Group Handicap (1200m).

"We have spoken to the Australian Turf Club and they will look to install electronic scales like they have in Japan which program in the weights," chief steward Ray Murrihy said.

"The club has acted quickly."

At the moment, weighing and weighing out relies on human involvement with the clerks of the scales recording the weights.

Murrihy said he had tried in the past and would try again to have the rules regarding refunds for disqualifications changed.

"I have tried without much luck to have the rule changed regarding the punter," he 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.

"The argument against has been that someone might take advantage and throw some weight away but we think the chances of that happening are minuscule."

The introduction of electronic scales gained attention last year when James McDonald weighed in light on a horse belonging to ATC chairman John Cornish.
