Dear mhaze,

Struts you present as an utter dill when you get out of your depth.

Ministers administer departments. He was sworn in as a minister for the other portfolios. He himself acknowledges it in the bloody report:

"Mr Morrison informed me, again through his
legal representative, that “neither [he] nor his office instructed PM&C not to gazette the
appointments”, and that he “assumed the usual practice would apply following the relevant
Ministerial appointments”. He subsequently explained that he understood the “usual
practice” to be that the appointments would be gazetted. This understanding was not
consistent with what I was told by PM&C, which is that the announcement of ministerial
appointments is the prerogative of the Prime Minister."

Both Menzies and Whitlam held other portfolios along with their usual office of Prime Minister and Cabinet. It wasn't done in secret though.

Finally Morrison jointly holding other ministries does increase the number of ministers. Why on earth claim such rubbish?

That should have read "doesn't increase".
