Precisely Screamer!!
If the organisers have gone through all the right channels - and they may well have done for all I know - you would think that the main Speedway bodies would be publicised as being in support of it, with the necessary logos on the website etc.
I'm sure it won't make a bit of difference to the average punter, but its the riders I would want to ensure are fully protected, in terms of any league contracts/ACU paperwork etc they may have signed?! I wouldn't want to see something fail before its even off the ground, if the correct permissions have not been obtained.
