would justify refusal of a decree for specific performance. 'The
respondent's case is founded upon what is called " mistake" in
equity - anistake not arising from fraud or default in the other
party to the contract, but from a mistake on his own part as
to the meaning of the language which he has used, with the
result that he has become bound in law to the performance of
a contract which he never intended to enter into. In applying
the remedy of specific performance the Court will in exercising
its diseretion disregard the rigorous rule of the law in one
respect. In law a party is bound, as I have already pointed out,
by the meaning which the law will attach to the words he has
used in a contract, whether that is or is not the meaning which
he intended they should bear. But a Court of Equity will not
foree a party to perform a contract if it is completely satistied
that he in fact never intended to enter into it, and that a hardship
amounting to injustice would be inflicted on him by holding him
to his bargain. The grounds upon which specitic performance
will be refused in such a case are well established. I can see no
difference in the doctrine laid down in Tamplin v. James (1),
and in the earlier cases such as Manser v. Back (2), although, no
doubt, in some of the earlier cases the application of the doctrine
has, to use the words of James L.J. in the former case, " gone too
far." I take the law to be as laid down by Baggallay LJ., and
approved by the Court of Appeal in Tamplin v. James (1). In
the application of the doctrine the Court must be clearly con-
vinced that the party resisting specific performance was in fact
mistaken as to the meaning of the contract by which he bound
himself. In Manser v. Back (3) Vice-Chancellor Wigram says : -
" That the defendant, who undertakes to prove such a case, under-
takes (as Lord Eldon said) a task of great difficulty, is not to be
denied. But if the difficulty be got over by evidence so stringent
that the Court may safely act upon it, why is not the principle to
be applied?" Again, care must be taken to distinguish between
the case in which the party alleges mistake as to the meaning of
the words he has used in a contract, and that in which, being well
aware of the meaning of the words he has used, his mistake has
been as to the effect of the contract on his own interests.
