Trainer Brendan Powell and former top jump jockey Graham Bradley have been found not to be in breach of the rules following a British Horseracing Authority disciplinary panel hearing last week over charges that Bradley was training horses under Powell's name.
The inquiry looked into whether Powell assisted, encouraged or caused Bradley to train horses to run in races which took place in England, Wales and Scotland despite him not holding a trainer's licence granted by the BHA, and then allowed them to run under his name.
In what was the first case of its kind brought by the BHA, Bradley faced similar charges, in that he was alleged to have trained horses to run without holding a licence, and that he encouraged Powell to act in a manner prejudicial to the integrity, proper conduct or good reputation of horse racing in Great Britain.
BHA media manager Robin Mounsey said: "We are obviously disappointed at the disciplinary panel's verdict, but it is impossible for us to comment further at present without being in possession of the panel's reasons for their decision. We will await the reasons and comment in due course."
Bradley, who has been assisting Powell, applied for a training licence in May last year but that has still to be approved.
Mounsey added: "BHA received an application for a trainer's licence from Graham Bradley on 28 May, 2013.
"However, Bradley was informed that his application would not be considered before the conclusion of this inquiry.
"It is too early to comment on how this process will now pan out but we will be in contact with Bradley to discuss the status of his application in due course. Again, the disciplinary panel's reasons will be integral to the way in which this matter is taken forwards."
