Jockey Frankie Dettori expects to learn on Wednesday what his punishment will be for failing a drugs test in France in September.
France Galop concluded its inquiry into Dettori's case this morning, with the rider's legal team saying he had received "a sympathetic hearing".
The 41-year-old jockey could be handed a six-month ban after testing positive for a banned substance at Longchamp on 16 September.
"We have had a very sympathetic hearing" - Dettori's solicitor
The French racing authority's medical commission held an initial inquiry last month before passing their findings on to the stewards for their consideration.
France Galop announced on 21 November that Dettori would be temporarily suspended from riding in France with immediate effect on medical grounds, although he has not actually ridden in public since taking part in the Melbourne Cup in Australia on 6 November.
Dettori's solicitor, Christopher Stewart-Moore, was in Paris for the hearing but will not comment on the case until France Galop have published their decision.
He said: "We have had a very sympathetic hearing and out of respect to France Galop, we will not be making any comment until such time as France Galop make their announcement, which we understand will be tomorrow morning."
The jockey had four rides at the Prix de l'Arc de Triomphe trials meeting, after which the sample was returned.
Dettori made the headlines in October when his 18-year association with powerful owners Godolphin came to an end, with the three-times champion jockey planning to ride as a freelance in 2013.
Perhaps the most recognisable face in British racing, Dettori's finest day in the saddle arguably came at Ascot in 1996 when he went through the card, riding all seven winners - a feat which has since been tagged 'The Magnificent Seven'.
Any ban could be reciprocated by racing jurisdictions worldwide.
