Ordinarily there is no further appeal. In some unusual circumstances, there may be order 56 judicial review to Supreme Court: see below on this page.
To Supreme Court by section 272 appeal
An alternative course sometimes used is pursuant to the Criminal Procedure Actss.272, 273 (formerly the section 92 appeal under Magistrates' Court Act and yet earlier known as order to review). It takes the case to a Judge of the Supreme Court. There is more detailed provision for such appeals provided by Supreme Court (Criminal Procedure) Rules order 3A.
Availability to prosecution. A feature of the s.272 type of appeal is that the prosecution has a much right of appeal as does a defendant. This contrasts with the quite limited right of prosecution appeal, otherwise available. Where the informant is a member of police, such appeals must be brought by the Director of Public Prosecutions on behalf of the informant: s.272(2). In practice this is usually done by naming the Appellant as "Director of Public Prosecutions (on behalf of...)". Prosecution appeals are brought quite sparingly. In practice, the Office of Public Prosecutions usually acts for the prosecution upon s.272 appeals from police prosecutions, whether it be a defence or a prosecution appeal.
Restrictions. The availability of an appeal such as s.272 appeal has some major restrictions.
* It is confined to "questions of law", for example the meaning of statutory provisions (the drink driving laws have been a major source of case), the common law, the rules of evidence etc. In practice the tendency is to entertain "errors of law", not merely areas of unsettled law.
* It does not allow a re-hearing of factual disputes. It is however to raise a "question of law" to argue that a Magistrate has made a finding of fact that no reasonable Magistrate could have made: Hardy v Gillette  VicRp36,  VR 392. This however is a difficult basis upon which to proceed, and is ill-advised except upon an extreme example.
* It does not allow a challenge to exercise of discretion by a Magistrate, although it is well settled that certain kinds of challenge to purported exercises of discretion do raise a "question of law". The leading case on this point remains Australian Coal and Shale Employees Federation v The Commonwealth  HCA 25, (1953) 94 CLR 621. To raise a question of law upon a purported exercise of discretion, it is necessary to argue the Magistrate has acted upon a wrong principle, allowed extraneous or irrelevant matters to guide or affect him or her, mistaken the facts or not taken into account some material consideration. "In such a case, although the nature of the error may not be discoverable, the exercise of the discretion is reviewed on the ground that a substantial wrong has in fact occurred." This however is also a difficult basis upon which to proceed, and is ill-advised except upon an extreme example.
* It must be from a "final order" (because s.272 expressly says so). The usual "final order" will be a conviction or dismissal, with the "question of law" based upon rulings that led to the result. A striking out of the charge is not enough: DPP v Moore  VSCA 90, (2003) 6 VR 430. An interlocutory order or a question raised but immaterial to the final order is not enough, nor are results of committal proceedings.
Commencement. A s.272 appeal must be instituted within 28 days after the day on which the order complained of was made: 272(3). This is strictly applied, though there is provision for leave to proceed out of time in exceptional circumstances and where there is no material prejudice any other party: s.272(8). The appeal is instituted by application to an Associate Judge of the Supreme Court without notice to any other person. The application is to be supported by affidavit filed before or upon the attendance. For a defence appeal, the informant named upon the charge should be named as the sole respondent. Upon appearance there will usually be attention to the Affidavit, and to questions of law said by the appellant to arise. It is good practice to have proposed questions of law drafted ready for the Associate Judge. If questions are approved, further orders will be made as to service on the respondent and the Magistrate, answering affidavits, reference to the listing system and other matters.
The affidavit. The affidavit is an account of the proceedings at the summary hearing. Typically it is sworn by the defendant, the instructor attending, the prosecutor or the informant. Sometimes it is sworn by the practitioner who appeared at the Magistrates' Court, though if this is so, it is inappropriate for the practitioner to appear on the appeal: R v Roberts  VSCA 2. The deponent of the affidavit is really a witness upon the appeal, and it is undesirable that a practitioner appearing should also be a witness. Recordings are now made of the proceedings at the Magistrates' Court. The affidavit may need little more than reference to and exhibiting the transcript. The affidavit should avoid new comment or argument, or references to background matters out of court. The affidavit should have all relevant exhibits within possession or power of possession, including a Magistrates' Court certificate of result and the charge.
The hearing. The hearing could be from within a few weeks or months from the appearance before the Associate Judge. With uncommon and slight exception, the facts as to the hearing at the Magistrates' Court are decided upon the affidavits. The usual practice is that there is no affidavit filed by the Magistrate. There is not always an affidavit filed on behalf of the respondent, especially where there is no contest with the contents of the affidavit filed on behalf of the appellant.
Remedy. The court may such order as it thinks appropriate: s.272(9). Frequently, upon successful appeal, the case will be remitted to the Magistrates' Court for re-hearing in accordance with law. By consent, the court might make a final order: DPP v Parsons VicRp 1, 1 VR 1. If it has been held there was a factual finding or exercise of discretion no reasonable Magistrate could make, the court might make the appropriate final order, regardless of consent.
Costs. If the appeal is dismissed, it will probably be with the costs of the other party to be paid. If the appeal succeeds, it will probably be with costs. A respondent ordered to pay costs may apply to the court for an indemnity pursuant to the Appeal Costs Acts.13.
The application for leave to appeal, and the appeal if leave is granted, is not a re-hearing of trial. It is essentially legal argument about what has occurred at trial.
The Court of Appeal ordinarily for a case of this kind is comprised of two or three judges of Appeal; occasionally more especially if the overruling of a precedent of the Court of Appeal is under consideration; usually only two for interlocutory matters. In any case, if the President of the Court of Appeal so determines, two Judges of Appeal constitute, and may exercise all the jurisdiction and powers: Supreme Court Act s.11; R v Sebalj  VSCA 106.
Applications to the Court of Appeal in Victoria against conviction by jury are governed inter alia by Criminal Procedure Act s.276(1) which provides
Determination of appeal against conviction (1) On an appeal under section 274, the Court of Appeal must allow the appeal against conviction if the appellant satisfies the court that - (a) the verdict of the jury is unreasonable or cannot be supported having regard to the evidence; or (b) as the result of an error or an irregularity in, or in relation to, the trial there has been a substantial miscarriage of justice; or (c) for any other reason there has been a substantial miscarriage of justice.
The first category, "unreasonable" or "cannot be supported", commonly known as "unsafeness", is by para (a). This has meaning from High Court authority which has developed an "unsafeness jurisdiction" relevant to the Victoria section, its predecessor, and other jurisdictions with similar provisions: Mejia (a pseudonym) v R  VSCA 296; SKA v R  HCA 13, (2011) 243 CLR 400; Libke v R HCA 30, (2007) 230 CLR 559; M v R  HCA 63, (1994) 181 CLR 487; Chamberlain v R No 2  HCA 7; (1984) 153 CLR 521.
A Court of Appeal in considering this kind of unsafeness ground must ask itself whether, upon the whole of the evidence, it was open to the jury to be satisfied beyond reasonable doubt that the accused was guilty. In considering that question, the appeal court must bear in mind that the jury has the primary responsibility of determining guilt or innocence and has had the benefit of seeing and hearing the witnesses. In most cases a doubt experienced by an appellate court will be a doubt which a jury ought also to have experienced. It is only where a jury’s advantage in seeing and hearing the evidence is capable of resolving a doubt experienced by a court of criminal appeal that the court may conclude that no miscarriage of justice occurred. A guilty verdict can only be said to have been ‘reasonably open’ to the jury if there was no aspect of the evidence which obliged - as distinct from entitled - the jury to come to a different conclusion: Farquharson v R  VSCA 296, (2012) 36 VR 538; R v Klamo v R  VSCA 75; (2008) 18 VR 644 (acquittal entered); further examples of acquittals entered O'Reilly v R  VSCA 19; CRR v R  VSCA 142, (2011) 32 VR 321.
The appeal court can have regard to a failure to give evidence at trial by an applicant in a position to know whether he or she committed the offence: MA v R  VSCA 214; Butler v R  VSCA 417, (2011) 34 VR 165.
Where a conviction depends upon circumstantial proof, it follows from the need for proof beyond reasonable doubt that the existence found by the Court of Appeal of a reasonable inference (or "hypothesis") consistent with innocence makes the conviction unsafe: Gant v R  VSCA 104 (allegedly fake Brett Whiteley paintings); R v Baden-Clay  HCA 35,  90 ALJR 1013; Knight v R  HCA 56, (1992) 175 CLR 495.
Another kind of "unsafeness" ground part of the first category is inconsistency of verdict as between counts against an accused: MFA v R  HCA 53, (2002) 213 CLR 606; Mackenzie v R  HCA 35, (1996) 190 CLR 348; Janes v R  VSCA 133; Carrott v R  VSCA 90; Ash v R VSCA 112; R v JA VSCA 169; R v Allen  VSCA 3; R v Le-Gallienne  VSCA 223; also probability of compromise verdict: R v Tran  VSCA 195. There may also be inconsistency of verdict as between separate accused at joint trial: R v Moroz  VSCA 30; R v Iliovski  VSCA 172, (2002) 135 A Crim R 117. There may also be inconsistency between verdict and failure to agree on verdict: Tukuafu v R  VSCA 345; Pillay v R  VSCA 249.
The second category, "error " or "irregularity", and third category "other", paras (b) and (c), are the remaining bases for appeal. It is important to be notice paras (b) and (c) require for successful appeal that there be "a substantial miscarriage of justice". There is a two-stage consideration. Has there been a miscarriage of justice? If so, is it a substantial miscarriage of justice? For the manner in which the latter is to be considered, see later in these notes.
As a general rule, miscarriage of justice cannot be made out unless it follows point taken by defence at trial: Xypolitos v R  VSCA 339.
Various points for grounds of appeal for miscarriage of justice under paras (b), or (c), or earlier approximating provisions, have been recognised by courts. Most would today be under para (b) "error" or "irregularity"; the incompetent representation, fresh evidence and new evidence points probably would be para (c) "other". The points include the following.
1. Erroneous statement or application of rules for admissibility or exclusion of evidence. This applies to all such rules howsoever exact or not so. An example of the less exact is the rule for admission of tendency evidence: Hughes v R  HCA 20; Bauer v (a Pseudonym)  VSCA 76. Another is the rule for exclusion of evidence improperly or illegally obtained: DPP v Marijancevic VSCA 355, (2011) 33 VR 440. Another is exclusion by the prejudice rule: Clarke (a Pseudonym) v R  VSCA 115.
2. Subject to severe confines, error concerning exercise of a judicial discretion at trial. Judicial discretion is any part of a decision by judge or other judicial officer being individual choice as provided by statute or common law. Miscarriage of justice cannot be found in the choice of itself. For an exercise of judicial discretion to be a miscarriage of justice, it must appear that the judge has either acted upon a wrong principle, been guided or affected by extraneous or irrelevant matters, mistaken the facts, or has not taken into account some material consideration. In such a case, although the nature of the error may not be discoverable, the exercise of the discretion is reviewed: Jamieson v R  VSCA 140 (discretion to permit change of plea to not guilty); Brewer (a Pseudonym) v R  VSCA 117 (discretion to order permanent stay); Najibi v R  VSCA 177 (discretion to discharge individual juror). The principles concerning review of discretion are general across various areas of law. In this conviction appeal context, commonly they are traced to House v R  HCA 40, (1936) 55 CLR 499 though it primarily concerned sentencing.
3. Inadequate or erroneous judicial instruction to jury. A trial judge is bound to direct the jury as to any principle of law or rule of practice applicable to the case and ordinarily summarise the evidence and the respective cases for the prosecution and the accused: Jury Directions Act 2015 ss.65-67; Murrell v R  VSCA 334; Papazoglou v R  VSCA 194; Alford v Magee  HCA 3, (1952) 85 CLR 437; Domican v R  HCA 13, (1992) 173 CLR 555.
5. Imbalanced judicial comment on facts or direction to jury, or unwarranted intrusion:Cook v R VSCA 174; Ramlagun v R VSCA 68; Piccolotto v R VSCA 143;R v Gose VSCA 66, (2009) 22 VR 150; R v Brdarovski VSCA 231, (2006) 166 A Crim R 366. As a general rule judicial comment to the jury is allowed providing it is made clear to jury that it is unbinding comment.
6. Failure to discharge jury without verdict due to impugned material or incident where there has been a high degree of need for such discharge. Whether such a need exists will depend upon the circumstances as seen by the judge in the context of the trial and the nature of the impugned material which is said to be prejudicial. However, and notwithstanding the position of primacy of the judge in such matters, there may be cases where an appellate court is driven to the conclusion that the exercise of the discretion adverse to the interests of the accused has occasioned the risk of a substantial miscarriage of justice: Crofts v R HCA 22, (1996) 186 CLR 427; Walker v R  VSCA 177; R v Halliday  VSCA 195, (2009) 23 VR 419.
7. Direction by the trial judge a late stage in the trial, that has the effect of materially changing the prosecution's case such as to add a new basis on which the jury could convict the offender, in circumstances where the offender is denied the opportunity of meeting the new case by moulding the defence to it through evidence or through the address to the jury:R v SAB VSCA 150;R v Nguyen VSCA 293.
8. Substantial possibility that jury mistaken or misled upon some material matter: Davies v R HCA 27, (1937) 57 CLR 170. An example is a collective misunderstanding of fact by parties and trial judge: NT v R  VSCA 213; R v Challoner  VICSC 356.
9. Incompetent defence representation at trial. The test to be applied when considering whether there was a miscarriage of justice by reason of the manner in which the trial was conducted is whether there was a rational basis for doing what was done: Mulligan (a Pseudonym) v R  VSCA 94; Nicholls v R  VSCA 250; Hajar v R  VSCA 233; Nudd v R  HCA 9, (2006) 80 ALJR 614; Ali v R  HCA 8, (2005) 79 ALJR 662; TKWJ v R HCA 46, (2002) 212 CLR 124.
10. Trial resulting from refusal to grant adjournment of trial to investigate a question where refusal was not reasonably open: SM v R  VSCA 332.
11. Lack of legal representation resulting in an unfair trial: R v Hoang  VSCA 117.
12. Inappropriate prosecution conduct: Whitehorn v R HCA 42, (1983) 152 CLR 657; Woods (a Pseudonym) v R VSCA 233;R v Russo  VSCA 206; R v Armstrong VICSC 350, 4 VR 533. Crown unjustifiably refusing to call witness wanted called by defence: R v Jensen  VSCA 266. Crown putting forward, for the first time in final address, a new basis on which it says the accused may be convicted, in circumstances where the defence has not had the opportunity of meeting the new claim: R v Howard  VSCA 235,
13. Judicial bias, actual or ostensible: Antoun v R  HCA 2, (2006) 80 ALJR 497.
14. Juror bias: Webb v R  HCA 30, (1994) 181 CLR 41; Zhu v R  VSCA 102; R v ALH VSCA 129, (2003) 6 VR 276.
15. Joinder of trial against separate accused shown inappropriate by subsequent events at trial: R v Alexander and McKenzie VSCA 183, (2002) 6 VR 53; R v Demirok  VicRp 19,  VR 244.
16. Procedural error, e.g. jury separation without required oath or otherwise irregular: R v Appleby (1996) 88 A Crim R 456; R v Chaouok VicRp 70,  VR 707.
17. Fresh evidence. This consists of evidence which either did not exist at the time of trial or which could not then with reasonable diligence have been discovered and raises a significant possibility that the jury might have acquitted if the relevant evidence had been led at trial: Mickelberg v R HCA 26, (1989) 167 CLR 259; Eastman v R HCA 29, (2000) 203 CLR 1; Tognolini v R  VSCA 222; Coleman v R  VSCA 301.
18. New evidence: This consists of evidence which was available at the trial or which could, with reasonable diligence, have then been discovered and which shows innocence, or a reasonable doubt as to guilt: Bowden (a pseudonym) v R  VSCA 46; Rich v R  VSCA 126, (2014) 43 VR 558.
Where there has been miscarriage of justice, the consideration whether it is substantial miscarriage of justice is according to leading cases Baini v R  HCA 59, (2012) 246 CLR 469 and Andelman v R  VSCA 25, (2013) 227 A Crim R 81, see also for example Di Giorgio v R  VSCA 335; Bass (a pseudonym) v R  VSCA 350. There is no single universally applicable definition of a substantial miscarriage of justice. That is because the possible kinds of miscarriage of justice dealt with by s 276(1) are too numerous and too different to permit prescription of a singular test. With respect to ss 276(1)(b) and (c), the types of substantial miscarriage of justice include cases where there has been an error or an irregularity in, or in relation to, the trial and the Court of Appeal cannot be satisfied that the error or irregularity did not make a difference to the outcome of the trial. Those paragraphs also cover cases where there has been a serious departure from the prescribed processes for trial. A substantial miscarriage of justice may occur where there has been a departure from process even if the verdict was open or it is not possible to conclude whether the verdict was open. The question whether there has been a substantial miscarriage of justice may be affected by the strength of the prosecution case. In such cases, however, the Court of Appeal must be aware of the natural limitations that attend the appellate task. A finding that the conviction was inevitable is merely relevant to the Court’s determination of whether there has been a substantial miscarriage of justice. It does not conclude the issue. If it is submitted that the verdict was inevitable, the appellant need show no more than that, had there been no error, the jury may have entertained a doubt. In assessing inevitability, the Court of Appeal must decide that question on the written record of the trial. In cases where evidence has been wrongly admitted or excluded, the Court cannot determine that there has been no substantial miscarriage of justice unless it determines that it was not open to the jury to entertain a doubt as to guilt. Otherwise, there has been a substantial miscarriage of justice because the result of the trial may have been different (because the state of the evidence before the jury would have been different) had the error not been made.
Remedies upon successful appeal. A new trial may be ordered or an acquittal be entered: Criminal Procedure Act s.277. The latter is in practice exceptional. The power to order a new trial extends to ordering a new trial for an offence for which the appellant could have been convicted at the first trial, including for example a lesser alternative offence provided by statute: AJS v R  HCA 27, (2007) 235 CLR 505. The factors which should influence an appellate court in exercising such a discretion will depend basically on all the facts of each individual case, the circumstances which surrounded the trial, the nature of the miscarriage of justice, the strength of the prosecution case and a full and fair balancing of the public interest and the personal interests of the successful appellant. Such considerations are not exhaustive. See R v Poduska  VSCA 147; R v Wei Tang  VSCA 144, (2007) 16 VR 454; R v Nicoletti  VSCA 175, (2006) 164 A Crim R 81; R v Redmond  VSCA 75; Edwards v R HCA 63, (1993) 178 CLR 213. See also R v Thomas (No 3)  VSCA 300 and R v Thomas (No 4)  VSCA 107 (fresh evidence since trial).
The Court is functus officio i.e. without jurisdiction to re-open a criminal appeal which it has already determined on the merits; there may be such a jurisdiction if the decision has been vitiated by fraud or some other circumstances which rendered its decision a nullity: R v McNamara VICSC 46,  1 VR 257; R v GAM  VSCA 185. There is however possible remedy by way of Petition of Mercy pursuant to Criminal Procedure Act s.327; see Tognolini v R  VSCA 222; R v Alexander VSCA 142; R v GAM  VSCA 23.
Extension of time for appeal or leave against jury verdict of guilty, or against sentence: Criminal Procedure Act s.313. The Court has regard to both the reasons for delay and the merits of the appeal, but these two considerations are not necessarily evenly balanced. Where the merits of the proposed appeal are very poor, even a satisfactory explanation for the delay might not justify an extension. On the other hand, where the merits of the putative appeal are very good, but the explanation for the delay is poor, the Court may incline towards granting an extension: Ludwig v R  VSCA 35; Roth (a Pseudonym) v R  VSCA 242; Bowling v R  VSCA 87; Jopar v R  VSC A 83.
Director's Reference. There is provision for prosecution reference of points of law to the Court of Appeal after acquittal at trial or upon County Court appeal, though the acquittal cannot be disturbed. These are known as a Director's Reference: Criminal Procedure Act s.308. In practice, very few are brought. An example (under previous legislation) is DPP Ref No1 of 2001  VSCA 89.
> To Court of Appeal against conviction by County Court or Supreme Court after plea of guilty
Conviction appeal in these circumstances is open if it appears (1) that the appellant did not appreciate the nature of the charge or did not intend to admit guilt, or (2) that upon the admitted facts could not in law have been convicted of the offence charged, or (3) that for any other reason there has been miscarriage of justice: R v Holden  VSCA 254.
> To Court of Appeal against sentence by County Court or Supreme Court
These are appeals concerning sentence first imposed by County Court or Supreme Court after jury trial or plea of guilty.
Criminal Procedure Act Part 6.3; Supreme Court (Criminal Procedure) Rules. The application if by a sentenced person initially is under Criminal Procedure Act s.278 for leave to appeal which usually is set down for a separate hearing in or if so elected by the applicant, determined on the papers without an oral hearing. Where it is held arguable that there has been a sentencing error, even with respect to an individual sentence, leave must be granted unless the judge is satisfied that there is no reasonable prospect that a less severe sentence would be imposed on appeal: Ludeman v R  VSCA 333.
To succeed on the appeal, it is necessary to establish matters such as specific error of statute, error of principle, weighting of sentencing factor not reasonably open, finding of sentencing facts not reasonably open, disparity with co-offenders or manifest excess of sentence: R v Taylor and O'Meally  VicRp 46,  VR 285. Another possible basis is procedural unfairness: Lennon v R  VSCA 85; R v Alexandridis VSCA 126.
Manifest excess of sentence is a non-specific error. Appellate intervention on this ground is not justified just because a sentence is markedly different from other sentences that have been imposed in other cases; the sentence imposed must be explicable only on the ground of a misapplication of principle, even if the statement of reasons of the sentencing judge does not make such misapplication apparent: Wong v R  HCA 64, (2001) 207 CLR 58. Appellate intervention on the ground of manifest excess is not warranted unless, having regard to all of the relevant sentencing factors, including the degree to which the impugned sentence differs from sentences that have been imposed in comparable cases, the appellate court is driven to conclude that there must have been some misapplication of principle: Quy Nguyen v R  VSCA 127; R v Pham  HCA 39, (2015) 256 CLR 550.
The remedy, if error had been shown and the court is satisfied a different sentence should be imposed, is re-sentence, or remittal to the County Court: Criminal Procedure Act s.281, s. 286. Re-sentence may be by more severe sentence but the court must warn the appellant, as early as possible during the hearing of the appeal, that the appellant faces such possibility: Criminal Procedure Act s. 281.
There is Court of Appeal power on a sentence appeal to give or review a guideline judgment: Sentencing Act ss. 6AA-6AG. This may set out (a) criteria to be applied in selecting among various sentencing alternatives; (b) the weight to be given to the various purposes specified in section 5(1) for which a sentence may be imposed; (c) the criteria by which a sentencing court is to determine the gravity of an offence; (d) the criteria which a sentencing court may use to reduce the sentence for an offence; (e) the weighting to be given to relevant criteria; (f) any other matter consistent with the principles contained in this Act.
In the Court of Appeal, fresh evidence which relates to events which have occurred since sentence will be received if it demonstrates the true significance of facts in existence at sentence to be harsher to the offender than had then been understood; such fresh evidence may vitiate the sentencing discretion: Redenbach v R  VSCA 2 (sentenced without awareness of parole cancellation on earlier sentence); Mileto v R  VSCA 161 (forfeiture); Spence v R  VSCA 197 (ill health); Marsh v R VSCA 6 (victim of offending subsequently forgiving); R v Cochrane VSCA 60 and R v Mourad VSCA 4 (after sentence cancellation of parole on another matter);R v Dang VSCA 183 and R v McLeod  VSCA 183, (2007) 16 VR 682 (forfeiture); R v Alashkar VSCA 182 (after sentence cancellation of parole on another matter); R v Jahanara VSCA 260 (lesser injuries to victim); R v Nguyen  VSCA 184 (hardship to family); R v Wooden  VSCA 97; R v SH  VSCA 83 (mental illness and need for protection); R v Pividor  VSCA 174 (protection required in prison);R v Spagnolo  VSCA 126, (2000) 114 A Crim R 98 (illness); R v Rostom VICSC 213, 2 VR 97 (protection required in prison);R v Eliasen VicSC 357, (1991) 53 A Crim R 391 (illness). Outside of these principles is evidence which does no more than show the working out of matters that were, in general terms, recognised and taken into account at the time of sentence: R v Jones  VSCA 266; R v McLachlan  VSCA 87, (2004) 8 VR 403.
There is a discretion to receive evidence that ought to have been but was not before the sentencing judge, the evidence being admitted to avoid a miscarriage of justice: R v Cako  VSCA 147; DPP v Burgess  VSCA  VSCA 135, R v Mandala  VSCA 159.
For prosecution appeals against sentence, the main provisions are Criminal Procedure Act ss.287-294. The right conferred upon the Director of Public Prosecutions to appeal against sentence is conditioned upon the Director being satisfied that there was an error in the sentence imposed, that a different sentence ought to have been imposed and that it is in the public interest that an appeal be brought; if the Court finds that there is an error and that a different sentence should be imposed, it must allow the appeal and if either of these requirements is not met, it must dismiss the appeal; the need to be satisfied that a different sentence should be imposed serves to preserve a residual discretion to dismiss an appeal even where error is identified: DPP v Karazisis  VSCA 350,  31 VR 279. The residual discretion can turn for example on the position taken by the prosecution on the plea: DPP v Abad  VSCA 279. In the event that prosecution appeal is allowed, the Court must set aside the sentence imposed by the originating court and impose the sentence, whether more or less severe, that it considers appropriate taking into account any factor, other than double jeopardy, that it regards as relevant to re-sentencing the offender: s.290; DPP v Karazisis. Manifest inadequacy: DPP v Zhuang  VSCA 96.
One breach of natural justice is bias, actual or ostensible: Antoun v R  HCA 2, (2006) 80 ALJR 497; Webb R HCA 30, (1994) 181 CLR 41; Livesey v NSW Bar Association  HCA 17, (1983) 151 CLR 288. Importance of requesting disqualification or objecting: Vakuata v R  HCA 28, (1989) 167 CLR 568; Humphrey v Wills VicRp 42, VR 439; Rozenes v Kelly  VicRp 20, 1 VR 320; Willis v Magistrates' Court (1996) 89 A Crim R 273.
An order at committal proceedings for Victorian offences committing for trial or refusing to commit is regarded as ministerial and not judicial and as not amenable to certiorari: Potter v Tural  VSCA 227.
It has become accepted, at least implicitly, that the County Court is an inferior court and not made otherwise by County Court Act s.36A. There is however some uncertainty whether certiorari can ever lie in County Court criminal proceedings which are between arraignment and conclusion on an issue which ultimately would be exposed to Court of Appeal criminal jurisdiction: McGuire v DPP  VSC 11. Note however Administrative Law Act s.12 by which any proceeding may be removed into the Supreme Court notwithstanding any provision to the contrary in an Act passed before such commencement.
There remains a discretion not to grant certiorari, mandamus or prohibition where a basis is made out. One reason tending against grant is where there is provision for an alternative and preferable remedy: Kuek v Victoria Legal Aid VSCA 80. Another reason tending against grant is the undesirability of fragmenting criminal trial proceedings: Iorlano v R  HCA 43, (1983) 151 CLR 678; Rozenes, ex parte Burd HCA 11; (1994) 68 ALJR 372; Phung v Victoria Legal Aid  VSC 1.
Loss in the Court of Appeal (even for the prosecution) is open to High Court appeal. There is though formidable special leave requirement before the substantive issues will be heard: see Constitution s.73, Judiciary Act Part V Division 1; Liberato v R HCA 66, (1985) 159 CLR 507. Special leave applications are often heard separately, typically in Melbourne if of Victoria origin. Remitter from High Court to Court of Appeal: R v Weiss (No 2)  VSCA 161.
