" Turning then to the argument that there was no
infringement of the prohibition in s.73 because
the deed of variation did not constitute a
'mortgage' occurring after the date of the
contract but was merely a consensual variation of
the pre-existing bill of mortgage, their
Lordships find themselves wholly unpersuaded that
this propostition is tenable quite apart from
authority. It is true that the bill of mortgage
secured all sums becoming due to the lender but
it is, in their Lordships' view, quite unarguable
that the advance, pursuant to the deed of
variation, of a further $18,300,000 to cover the
cost of a new building did not constitute a
further charge on the land and thus a mortgage as
defined in s.71(2)(c) of the Act. Prior to the
deed of variation the land was not charged with
this sum. Afterwards it was. This hardly
requires to be supported by authority but if any
is required it is to be found in the decision of
the Full Court of the Supreme Court of Queensland
in Landers v. Schmidt which is, in all material
respects, indistinguishable from the instant
case."
