assumption I accept as correct the judgment of Bowen L.J. in
Gardner vy, Jay (1), where he said : - ' Now Order XXXVI, rule 3,
gives the Court discretion to decide upon the mode of trial in a class
of cases of which this is one, That discretion, like other judicial
discretions, must be exercised according to common sense and accord-
ing to justice, and if there is a miscarriage in the exercise of it it will
be reviewed, but still it is a discretion, and for my own part I think
that when a tribunal is invested by Act of Parliament or by Rules
with a discretion, without any indication in the Act or Rules of the
grounds upon which the discretion is to be exercised, it is a mistake
to lay down any rules with a view of indicating the particular grooves
in which the discretion should run, for if the Act or the Rules did not
fetter the discretion of the Judge why should the Court do so? As
to Cardinall v. Cardinall (2), though it is very convenient that a
Judge of first instance, who is going to exercise the discretion in
these cases from day to day, should indicate to those who are prac-
tising before him the kind of way in which his mind operates on such
questions, still when he does so he is not laying down a rule of law
nor fettering his own discretion, and, @ fortiori, although it is of great
value to hear anything that such a master of practice as Mr. Justice
Pearson says on such a subject, he cannot fetter the discretion of
another Judge where the rule has left the discretion open. If it
were wished to lay down rules as to how a Judge should act about
sending cases to be tried by jury, I do not think that anything
could be laid down more definite than this, that as the mode of trial
by jury differs in many respects, which lawyers know, from trials
before a Judge without a jury, the Judge must carefully consider
what those differences are, and what are the facilities for trial in
