I actually rechecked the rules last night and I have to apologise for what I told you previously.
Appeals against raceday decisions regarding horses i.e. relegation, disqualification etc are not permitted.
Appeals against horses for no raceday decisions like drug hearings etc are permitted to the Racing Appeals Tribunal which is part of JCA. They look after all these things.
Appeals by hosemen for raceday and non raceday decisions can be appealed to the RAT.
However that is as far as it goes.
Racing Act 2003 forbids appeals against decisions of the Racing Appeals Tribunal.
Means you get one shot at it and you can't go to the Courst.
Exert Racing Act 2003
21 Appeals against placings and stakes
(1) No person is entitled to appeal to any appeals tribunal against
any decision made by a judicial committee on the day of a race
in respect of placings in that race or stakes payable for those
placings.
(2) Nothing in subclause (1) prevents a judicial committee, at any
time after the day of any race, from disqualifying a horse for a
race, and making any order the committee considers appropriate
as to the alteration of the placings in the race and the stakes
payable for those placings,—
(a) on a ground relating to a drug, stimulant, or depressant
having been administered to the horse; or
(b) on the ground that the horse was ineligible to start in the
race; or
(c) on any other ground on which, under the relevant racing
rules, a horse may be disqualified for a race after it has
started in the race.
(3) If a judicial committee decides, after the day of a race, that
a horse should be disqualified for the race on any ground referred
to in subclause (2), the owner of the horse may appeal
against the decision to an appeals tribunal.
The decision of the Appeals Tribunal shall be final, shall bind all bodies and persons and
shall not be subject to any appeal under these Rules.
