For what it's worth, I don't believe the Code is contradictory on this.As pointed out in earleir posts, there are areas it explicitely states the opposite. It's not super clear. And as posted, there have been cases where councillors have been held to account for acts in their private life. I guess @Steve Foster does not help himself though, given he throws the 'as a councillor' line around freely and frequently.
The section I've seen you quote previously saying "on all occasions" is in the section about Councillor conduct, in other words it means on all occasions while in the role of Councillor.
The following section that I quoted is about when the code is applicable, so in affect when somebody can be said to be acting in the role of Councillor.
I might add, that if I was clearer on what exactly you're proposing to complain about, I may well agree with you that it applies.
