The Coroner has recorded three misadventure verdicts on the competitor and two spectators who died in an accident at the end of last year's Centenary TT.
The fatal crash, at the 26th Milestone in the Senior Race, claimed the lives of rider Marc Ramsbotham, Dean Jacob from Kidderminister and Gregory Kenzig from Australia.
In his summing up Michael Moyle referred to a catalogue of disasters involving marshals, the Manx Motorcycle Club and the Department of Transport.
He said the positions of some of the key people involved were now untenable, and that while he had no power to ban or exclude them, they should have no significant participation in future motorcycling events in the Isle of Man.
Mr Moyle also said the two spectators would be alive today had they not been allowed in a restricted area.
