OF COURT - COSTS
The appellant appeals against both sentence and conviction entered by a Magistrate. This Court
previously made orders allowing the appeals and setting aside the conviction on the basis the
respondent acceded that an error of law was made by the learned Magistrate.
The parties remained in dispute both about whether the matter ought to be remitted to the Magistrates
Court for re-trial or otherwise dismissed and on the question of costs arising from the appeal.
Held:
(1) The interest of justice weigh in favour of remitting the matter for re-trial particularly in having
regard to the public interest in the proper administration of justice which involves the prosecution of
offences, and the consequent specific and general deterrence that this provides at [16].
(2) The respondent is to pay the appellant’s costs of the appeals fixed at $570.00, being the
amount of the associated filing fees at [17].

[2025] SASC 89
Magistrates Appeal: Criminal
1 GRAY J (ex tempore): This is an appeal by Mark Rudy Nielsen against a
conviction imposed by Magistrate Kleinig on 12 November 2024, for the offence
of exceed speed limit 10-19 k/h (camera offence). A notice of appeal against
sentence was filed on 15 January 2025, and a notice of appeal against conviction
was filed on 9 April 2025.
2 The respondent did not take any issue with the late filing of the notice of
appeal against conviction and on 24 April 2025, the respondent filed an outline of
argument setting out the basis for conceding the appeal.1 The respondent submitted
that there was an error of law in the learned Magistrate’s reasons in that the
incorrect offence was identified and the respondent sought orders that the matter
be remitted back to the Magistrates Court for re-trial. The correct offence being
an offence against r 20 of the Australian Road Rules.
3 On 29 April 2025, this Court made orders that the appeal be allowed, and the
conviction be set aside. Those orders were not opposed and were made by consent.
The appellant, however, opposed any order remitting the matter for re-trial in the
Magistrates Court. A remaining issue in dispute on this appeal is whether this
Court should remit the matter to the Magistrates Court for re-trial or dismiss the
information filed on 24 April 2025. There is also a dispute concerning the question
of costs of the appeal.
Submissions of the parties
4 I have considered the detail of both the written submissions and the oral
submissions made by the appellant in this matter concerning the question of
remittal. There are five central submissions advanced by the appellant concerning
the question of the remittal.2 These are:
1. That the prosecution has had the opportunity to run the trial and lost on
appeal.
2. If the matter is remitted to the Magistrates Court, the appellant would be
entitled to the plea of autrefois acquit.
3. There would be prejudice in requiring the appellant to articulate on appeal
the original grounds of the appeal, as this would result in prejudice for the
re-trial.

4. No re-trial should be ordered by reason of the principles of double jeopardy
and in making these submissions, the appellant relies upon the reasons of
Justice Peek in Police v Hanton3.
5. That remitting the matter back to the Magistrates Court for a re-trial should
only occur in particular circumstances that were not applicable in this case.
In making this submission the appellant relied upon the decision of this
Court in Police v Shah.4
5 Section 42(5) of the Magistrates Court Act 1991 (SA) gives power to this
Court to make a number of orders in determining a criminal appeal from the
Magistrates Court. These powers include the power to remit a case for hearing or
further hearing before the Magistrates Court.5 The respondent submits that the
principles enunciated by the High Court in Director of Public Prosecutions
(Nauru) v Fowler6 concern the manner in which this discretion may be exercised.
In that case, the Court held:7
The power to grant a new trial is a discretionary one and in deciding whether to exercise it
the Court which has quashed the conviction must decide whether the interests of justice
require a new trial to be had. In so deciding, the Court should first consider whether the
admissible evidence given at the original trial was sufficiently cogent to justify a
conviction, for if it was not it would be wrong by making an order for a new trial to give
the prosecution an opportunity to supplement a defective case. … Then the Court must take
into account any circumstances that might render it unjust to the accused to make him stand
trial again, remembering however that the public interest in the proper administration of
justice must be considered as well as the interests of the individual accused.
6 The respondent contends that the admissible evidence received at the original
trial was sufficiently cogent to justify a conviction of the correct offence. Further,
the respondent contends that the reasons given by the learned Magistrate indicate
that the evidence satisfied each element of the correct offence. The respondent
contends that a re-trial would not give the prosecution an opportunity to
supplement a defective case. Finally, the respondent submits that any unfairness
to the appellant in terms of costs, inconvenience and stress in having to stand trial
again is outweighed by the public interest in the proper administration of justice.
7 It is submitted that the public interest in specific and general deterrence
requires that traffic offences (when an election is made by an accused not to
expiate) should be fully prosecuted if there is sufficient available evidence to do
so. It is said that the public interest in such prosecutions is not diminished in
circumstances of this case where an error of law was made in the original
conviction by the learned Magistrate. It is submitted by the respondent that the

prosecutor had identified the correct offence in the opening of the original trial.8
Finally, the respondent provides reasons as to why the appellant’s submissions
should not be accepted by this Court.9
Consideration
8 I accept that the power to grant a new trial is a discretionary one, and that in
deciding whether to exercise this power, consideration must be given to whether
the interests of justice require that a new trial be held.10
9 I have considered the submissions advanced by the appellant to the contrary.
I am not persuaded by the appellant’s contention that the prosecution has had the
opportunity to run its trial and that this alone would be a good reason for declining
a re-trial. I am also unable to accept the reliance that the appellant places upon the
plea of autrefois acquit, as this is a species of estoppel by which the Crown is
precluded from reasserting the guilt of an accused person when that question has
previously been determined against it.11 I am unable to accept that principle has
application in this case because on a remittal, there would be no prior extant
judicial determination of the guilt or innocence of the appellant. Orders have
already been made in this matter by consent on 29 April 2025, that the appeal be
allowed and the conviction set aside.
10 I note that the appellant confirmed that he does not wish to proceed with the
other arguments set out in the original grounds of appeal and the matter before the
Court today concerns only the question of remittal. On the question of remittal, in
my view, the reliance placed by the appellant upon the decision of Justice Peek in
Hanton12 does not assist the appellant in the manner in which the appellant states.
That case is distinguishable because counsel for the prosecution conceded on the
appeal in Hanton that if it was found that the prosecution could not avail itself of
the statutory presumption, then the other observations of the police officer could
not support a finding of guilt beyond reasonable doubt on either charge.13 There
has been no challenge on this appeal to the ability of the prosecution to avail itself
of the statutory presumptions in respect of the certificates and the certificates were
the matters relied upon by the learned Magistrate as being cogent evidence in
support of the prosecution case.14
11 The final matter relied upon by the appellant concerns the principle of double
jeopardy. As a matter of general principle, the principle of double jeopardy often
involves the misuse of the authority of the State and the potential oppression that

may be involved in a double trial or double risk of conviction.15 The appellant has
not in this case identified how the remittal of this matter would be vexatious or
amount to the misuse of State power or be potentially oppressive to him such as to
give rise to the application of the principle of double jeopardy.
12 I also find that the general principles referred to in the decision of Shah,16 do
not assist the appellant in the manner contended for by the appellant on this appeal.
That case concerned a prosecution appeal. The circumstance of this case which
concerns the interest of justice in the question of a remittal where there has been
an error of law made by the learned Magistrate involves a different issue. Whilst
I have considered the arguments advanced by the appellant, both in the appellant’s
written submissions and in the oral submissions made before this Court, they do
not persuade me that this matter should not be remitted. The appellant in
submissions did not identify on this appeal a deficiency that supports a submission
that the prosecution case was grossly deficient or the manner in which the
prosecution would, on remittal, be permitted to supplement deficiencies in the
prosecution case.
13 In determining where the interest of justice lies, I have had regard to the
question of whether the admissible evidence given in the original trial was
sufficiently cogent to justify a conviction.
14 In this case, the respondent contends that the admissible evidence received at
the original trial was sufficiently cogent to justify a conviction. I accept that
submission in the sense that the prosecution case at trial relied largely upon
certificates and statutory aids to prove the offence. Whilst the appellant challenged
the admissibility of those documents, the appellant at the trial in the Magistrates
Court did not call any evidence to support the challenges that he made to the
certificates which were relied upon by the prosecution as statutory aids. Having
regard to these matters, there is no evidence before this Court which would suggest
that this is a case where a re-trial would give the prosecution an opportunity to
supplement a defective case. It will be a matter for the appellant as to how on a
remittal if the charge is contested the defence will be conducted.
15 I accept that the conviction has been quashed on appeal because the learned
Magistrate erred in respect of the identification of the offence. I accept that having
regard to the transcript that that error occurred in circumstances where the
prosecutor had identified the correct offence in the opening of the original trial.17
16 I accept that there is cost, inconvenience and stress which will be occasioned
to the appellant by reason of having to stand trial again in the Magistrates Court.
Balancing the interest of justice however, and having consideration to the public
interest in the proper administration of justice, which involves the prosecution of

offences, and the consequent specific and general deterrence that this provides, I
would remit this matter to the Magistrates Court.
17 The final question to consider is the question of the costs of the appeal. Both
parties have provided detailed written submissions on the question of the costs of
the appeal. The respondent seeks that there be no order as to costs and the appellant
seeks that costs be awarded in his favour in the amount of $2,513.00. I have
considered the provisions of s 42(5)(c) of the Magistrates Court Act 1991 (SA)
which authorise this Court to make orders with respect to costs as are necessary
and desirable in the circumstances as well as to the general principles and
authorities concerning the question of costs.18 I have considered the submissions
made by both parties as to the costs that have been incurred, including the
submissions of the Crown concerning the costs associated by the dispute
concerning the question of remittal. In the exercise of my discretion, concerning
costs I would make an order that the respondent pay the appellant’s costs fixed in
the sum of $570.00 being the amount of the two filing fees paid by the appellant
to lodge the appeals before this Court.
Conclusion
18 It follows that I would order:
1. The matter be remitted to the Magistrates Court for re-trial.
2. The Commissioner of Police pay the appellant’s costs fixed at $570.00.
3. The question of costs of the trial in the Magistrates Court will be determined
by that Court.
19 I note in making these orders that the appellant has not identified any relevant
prejudice from the matter once remitted before trial being determined by the same
Magistrate. It will be a matter for the Magistrates Court as to which Magistrate is
allocated to this matter on remittal.
20 I will hear from the parties as to any other orders.
