I think I'm cleared to speak for the government when I say that our nominees for both the Presidency and Justice positions were agreed upon during our coalition talks.
There was no constitution nor indeed was it argued for at that time. So how could there have been placeholders?
We had already concluded that basic Constitution was necessary to address some of the concerns raised during the provisional session and had largely agreed upon the basic tenets, which included both positions.
If that was mentioned publicly, I'd like to see where.
I don't know if it was or not. Coalition negotiations aren't usually public and as for my drafting of the Constitution Act I consulted with my Cabinet colleagues before submitting the draft to the house, upon which point it was amended by various members of Parliament.
In any event, the government is delighted with the successful nomination of both Hagrid and Hashemite and we've every confidence they'll carry out the duties of their offices with dignity and skill. There's not much else to say.
