Ex-jockey Allan Robinson is now likely to attend the John Singleton – Gai Waterhouse inquiry revolving around More Joyous when it resumes possibly at the end of the week or early next week.

Robinson was one of three key witnesses who didn’t front up yesterday at Racing New South Wales headquarters in Sydney and will be “invited again” along with Rugby League legend Andrew Johns and high profile punter Eddie Hayson who also failed to appear.

“Racing New South Wales wishes to thank all those that attended today’s inquiry, but we are disappointed with the three failings to co-operate,” Racing New South Wales chairman of stewards Ray Murrihy said.

“These three people are in a chain of information that is central to the issue. We will contact these three people one more time in order to afford them the opportunity to appear. Should the three people once again fail to appear, recommendations will be made to initiate proper sanctions.”

Chris Murphy, representing Robinson said today in a tweet that “Subject to medical clearance and an absolute guarantee of civility and consideration my client Allan Robinson will attend Inquiry.”

Scenes outside the Druitt Street headquarters were chaotic as the key players, Singleton, Gai Waterhouse and her bookmaker son Tom Waterhouse arrived and entered the building to a waiting thong of journalists.

With Johns gone into hiding, the inquiry failed to find out what exactly he said to Singleton in their Saturday morning phone conversation in which Singleton said he was told that his mare More Joyous was “off” and couldn’t win the Group 1 $400,000 Yarraman Park All Aged Stakes (1400m) at Randwick on April 27.

Murrihy expressed disappointment that the three key players failed to show up but kicked off proceedings with Gai Waterhouse’s foreman David Meijer being called as the first witness.

The inqury heard evidence from Meijer as well as Singleton’s racing manager Duncan Grimley and veterinary surgeon Dr John Peatfield, all agreeing that More Joyous had been under treatment for a minor neck problem.

Gai Waterhouse stood her ground when Murrihy asked if she had told Tom or her husband Robbie of More Joyous’ problems, with the top trainer replying a stern “No” and added “I’ll swear on a bible I didn’t talk to my husband or son about the horse’s condition.”

The afternoon session started to deteriorate in a slanging match with Gai and Tom questioning how many drinks Singleton had at the races before he launched into the trainer pre-race and post-race with suggestions that she had informed Tom of More Joyous’ condition.

Singleton replied that he had two or three beers and no mediaction.

Gai Waterhouse then added “You’re an absolute sham, John.

“This has all come from a footballer, a brothel owner and a trumped up jockey and you’ve used it to discredit my son, my husband and myself.”

The inquiry was adjourned after the six hour hearing with the resumption date to be confirmed.

“We will be giving consideration to the large volume of evidence at hand and whether charges will be laid, and we hope to bring this inquiry to a swift and satisfactory conclusion,” Murrihy said.
