Luke Comer has been declared a disqualified person from racing after failing to pay more than €1.3 million owed to the Irish Horseracing Regulatory Board. It is the latest and most significant development in a case that has already carried a three-year training ban and major financial penalties.
The ruling means Comer cannot own or train racehorses while the arrears remain unpaid. That is a serious step in Irish racing, and it comes after a long-running process tied to what has been described as the biggest drugs scandal in Irish racing history.
Comer, who is based in Monaco, has remained a visible figure in the sport despite his suspension. On Sunday, he was at the Curragh for the Irish Champions Festival and presented the trophy for the Comer Group Irish St Leger.
The debt that triggered the ruling
According to the Irish Horseracing Regulatory Board, the appeals body considered Comer’s appeal in May 2024 against the September 2023 decision of the referrals committee relating to adverse analytical findings. The appeals body confirmed penalties imposed for breaches of Rule 96(a) and Rule 96(b)/(c), directed that the fines be paid by July 15th, 2024, and awarded costs in favour of the IHRB.
The IHRB has now said those fines remain unpaid and the costs awarded to it remain outstanding. It added that sums due to the IHRB which are not paid when due or on demand constitute arrears.
That matters because Rule 165 provides that the forfeit lists shall include such arrears by whom they are due. The forfeit list is maintained and published by Horse Racing Ireland in accordance with HRI directive eight.
From punishment to disqualification
The disqualification is the practical consequence of those unpaid sums. Earlier in 2026, the IHRB went to the High Court in relation to the fine and costs, underlining how far the case had moved beyond the original disciplinary hearing.
Comer had already lost his licence to train horses for three years in 2024, but this latest ruling goes further by formally barring him from racing activity while the debt remains unresolved. For a businessman who has continued to sponsor the sport, the decision is a clear reminder that financial penalties cannot simply be left hanging.
Comer himself has previously said: “I spend just three months of the year in Ireland.” But the rules applied by the IHRB are not softened by how often a person is in the country.
What now matters is whether the unpaid sum is settled. Until then, Luke Comer Horse Racing Disqualification is not just a headline: it is the status that now defines his place in the sport.
