The FEI has confirmed that the B Sample from Denis Lynch's Olympic horse Lantinus has returned positive for the banned substance capsaicin.
The next step will be a written submission and evidence from Lynch on the application of the derivative of the chilli pepper plant.
A three-member panel of show jumping’s governing body has been appointed to the hearing which will take place from 5-7 September in Lausanne.
Horse Sport Ireland has confirmed that Lynch will be taking up his right to a hearing.
Although capsaicin has always been prohibited, it is only in the last two years that the technology has been developed to detect it because it disappears quickly from a horse's system.
In human medicine capsaicin is used in cases such as neuralgia - a painful disorder of the nerves - by producing both a burning and pain killing effect.
