circumstances require.'
a determination by the Court that the appellant was wrongly con-
victed. It is an elementary principle of criminal justice that, in
the absence of clear statutory provision in that behalf, a man shall
not be twice put in jeopardy in respect of the same charge (R. v.
Miles (1); R. v. Dyson (2); R. v. Simpson (3); Haynes v. Davis
(4); R. v. Sheridan (5)). There is, in my opinion, nothing in the
phrase " and may make such further order in the premises as is just
and the circumstances require' which indicates an intention on
the part of the legislature that a man who has been tried once, has
been wrongly convicted, and has succeeded in having that wrongful
conviction quashed, should be again put in peril by being subjected
to the risks of a second prosecution. There is nothing to suggest
that the phrase was intended to do more than enable the Court to
make such ancillary and consequential orders as are necessary to
make its order to quash properly effective. No doubt if the convic-
tion were quashed on the ground that the trial had been a nullity
there would be nothing to prevent a further trial, but that would
be because there had so far been no trial at all and the appellant
had therefore never been in peril. In such a case an order for a new
trial would be harmless but otiose. No trial having in law occurred
a trial should be proceeded with whether any order be made in that
behalf or not (Crane v. Director of Public Prosecutions (6) ; Ex parte
Malouf ; Re Gee (7); R. v. Cronin (8) ; Halsbury's Laws of England,
2nd ed., vol. 9, par. 407, pp. 278, 279). This applies to summary
convictions as well as to convictions on indictment (R. v. Marsham
(9); Bannister v. Clarke (10)). But if there has already been one
trial there cannot be a second however bad the mistakes in the
conduct of the first.
