Stewards last week invoked Rule 183 to prevent Rattray from nominating any horses until they finalise a positive swab inquiry (set down for June 7).

His horses were not allowed to race last weekend.

However Rattray appealed the decision and his case was due to be heard on Tuesday.

It did not proceed after stewards questioned whether the Appeal Board had the jurisdiction to rule on the matter.

The Appeal Board found that it did and, due to the fact that Rattray was unable to have his case heard as scheduled, granted him a stay of proceedings.

No date has been set for the appeal and it may not even be heard before the stewards’ inquiry which is only three weeks away.

Rattray has three horses entered for Hobart on Friday night and three for Mowbray on Sunday night.

Beauty Point trainer Rohan Hillier boasts an impressive 40 per cent strike-rate this season and it should be even better after this week’s meeting at Mowbray.

Hillier has had 22 winners from only 55 starters in 2017-18.

He will have only one runner on Sunday night, recent stable addition Overpowering, and the former Victorian gelding looks the horse to beat in the 3YO Pace.

At his only start in Tasmania, Overpowering sat outside the leader before winning the $12,000 Max McCormack at Devonport.

Hillier drove him on that occasion for Cranbourne trainer Michael Hughes.

Connections then decided to leave the horse with Hillier.
