More on coat of arms

I noticed, in passing today, that Eleni Evangel's billboard on Beaufort Street has had the state coat of arms covered over by a piece of blue plastic (which is nevertheless in danger of blowing off).

I don't know when the WA Today photograph (see my previous post http://ianrker-vincent.blogspot.com.au/2017/03/illegal-political-advertising-misuse-of.html) was taken (although it is presumably recent for the story to benewsworthy), but covering up the coat of arms on the Beaufort Street billboard is tacit acknowledgment that its use was, at best, inappropriate.

I questioned the legality with the Electoral Commission, which replied (very quickly - perhaps indicating that I was not the first to raise the issue):

Use of ‘common badging’ and the State Coat of Arms during the caretaker period is a matter for the Department of Premier and Cabinet under Caretaker Conventions.The Electoral Act 1907 does not address the use of such images during campaign periods. 

The Caretaker Conventions do not specifically mention election advertising, but do state:

This would appear to exclude use of the State coat of arms for any other purpose, including election advertising.
