The investigations manual of any regulatory authority does not have to be, and should not be, a public document.
I see Mr McCormick appears to have been fooled into setting up a delegations regime that delegates powers to numerous positions, thereby giving independent discretion to numerous people and unnecessarily inviting allegations of inconsistency and favoritism.
There’s a way to fix that, Mr McCormick: Delegate the controversial powers to the occupant of
only one or maybe two positions that are
very close to you.
My suggestion is that you pick someone who’s always whispering in your ear about what you and everyone else should decide. That way, they’ll not only be able to tell you and everyone else what decision should be made, and why: they’ll be responsible for making the decision themselves!
At the next meeting of the CASA executive, look around the table and ask each attendee: How often have you actually put your name, as delegate, on some decision that’s grounded a fleet of aircraft, ended a career or put an organisation out of business? If you get to someone who’s been in the organisation for a very long time, and the answer is “not many” or “none”, pick them too.
