Lousy of her not to drop in on her client Ralph.   Probably unethical too.   And viewed as part of the Wilson/Gillard course of conduct............

Here's StevenJ with his take

"The prime purpose of the PoA was not to sign the Contract but to secure a mortgage in Blewitt's name from Johnathan Rothfield, a mortgage lender who was a former solicitor then consultant working for Slater & Gordon."
That is an interesting thought.
The POA wasn't needed for the auction.
Wilson could have used his own name and substituted Blewitt later.
There presumably being no indication Blewitt wouldn't agree to everything requested of that nature.
If its purpose was to allow the mortgage to be executed its use for this purpose was not authorised by its terms.
If this was the purpose Gillard could have organised something when she was in Perth for the hearing by creating a (new) POA which refer directly to borrowing.
Therefore if its purpose was to facilitate the mortgage an allied purpose must have been to do this without Blewitts knowledge ie to have a POA which ostensibly made no reference to borrowing but which could through contacts be used for that purpose.
The only reason I can think of for this is the most obvious one; they thought he wouldn't agree to do this.
There remains the mystery if this is so of the first two payments of interest from Blewitts account.
The loan was actually assigned by Rothfield before the first interest payment was due (I think).
It is reasonably clear that Blewitt was reimbursed for these payments from the WRA. Who knows what story he might have been told to get him to process the transactions.
However it is clearly a pattern he would have been used to ie withdrawing funds from the WRA to run them through his account before forwarding to S&G.
A possible reason could lie in the fact that it is possible for a Principal to ratify the acts of an Agent which are actually beyond that Agents authority.
The first two interest payments would amount to a ratification of the actions of Wilson in organising the loan.
Nothing much in this whole saga seems to have occurred without a purpose, so why not this.
I do not believe that it happened as a result of Periodic Payments set up by Wilson.
Gillard admitted she had never performed a conveyance so I always assumed that the reason for the POA was a misapprehension on her part that it was necessary.
Perhaps I underestimated the cunning involved.
