In short:
According to you, the sign and markings you were in contravention, but whether there is a lawful restriction to contravene only the traffic order would reveal.
Likelihood that the order does not and that you are in the clear? Low.
Perhaps you were engaged in an exempt activity? I see no point in setting out what these are, all you should do is respond to the questions already posed regarding what you were doing and for how long you were parked.
Perhaps the CEO had not begun to prepare a PCN? This is a matter of fact. You don't know and no-one else knows other than the CEO and council. This is a technical area regarding the meaning of 'begun to prepare' as opposed to carrying out ancillary checks and thought processes to establish a belief in the CEO's mind that a contravention had occurred.
Likelihood that they hadn't? IMO, low. The 'loading' info is at best inconclusive. Why a challenge would simply assert as opposed to revealing the basis of your thinking, I don't know e.g. I note from the PCN log that ** occurred at ** whereas the PCN was not 'loaded' until *** which leads you to believe that the CEO had not ......
We're looking at probabilities, not possibilities. I wouldn't want your hopes to be raised to a false level on the back of possibilities.
