There were some questions raised which it is not necessary now
to decide - questions of great interest and some little difficulty
which may have to be considered at a future time. One of them
is as to the necessary parties, whatever the equities may be, who
must join in the release of a mortgage. But on the document
before us the matter can be resolved very simply. The learned
primary Judge thought, as I understand, that the mortgage,
apart from the portion of the first proviso which is objected to,
was to be considered as a joint mortgage, and that the portion
objected to sought to modify the mortgage so construed and to do
so in an objectionable way. He said that he was not considering
whether, if at the foot of the mortgage the mortgagees had
chosen to say that, as between themselves, they held the mort-
gage in specific shares, setting out the proportions, the Commis-
sioner could have refused to register the mortgage containing
that statement. But he thought that from the position of the
portion objected to, as well as from its words, it had been woven
into the fabric of the mortgage in a manner which made the
whole document substantially not what it would otherwise have
been. I think that that mode of approaching the matter has led
to error. When the document is looked at as a whole, it does not
amount to a joint mortgage in the sense to which I have referred.
It is a mistake to construe a document apart from any given
portion of it first and then to see what change has been made by
that portion. The meaning of each and every part of the docu-
ment must be ascertained by reference to the whole document.
When this particular document is looked at as a whole, it is found
that nowhere is it stated expressly that the advance is a joint
advance. There are words which are capable of that implication
if nothing more appeared, but, when these particular words are
put in defining the several interests of the mortgagees, then that
implication is impossible because the parties have expressly stated
what they mean. :
