So if I'm understanding this correctly, the Supercars Commission didn't make the changes to the Holden but, they delegate the capacity to make a decision to the Technical Department and they made the change?
If it's a case of the Technical Department making a change without the authority of the Commission, then how is that possible? Regulations were followed, changes were made. We don't have to like it & if it led to the resignation from the Commission of Crompton & Kelly, they obviously don't agree with it either and have taken what they deem appropriate action.
It all seems black or white to me with no grey area at all.
Having said all that, 2019 has been a technical mess of unprecedented proportions. Worrying times indeed.
