Section 230 gives the National Court every power it could need, and then confines the use of them to one situation. Understanding both halves is the key to framing an appeal.
The powers
On the hearing of an appeal, the National Court shall inquire into the matter, and may (a) adjourn the hearing from time to time; and (b) mitigate or increase a penalty or fine; and (c) affirm, quash or vary the conviction, order or adjudication appealed from, or substitute or make a conviction, order or adjudication which ought, on the evidence before the National Court, to have been made by a District Court; and (d) remit the case for hearing or for further hearing before the Court which made the decision or any other competent court; and (e) exercise a power that the Court that made the decision might have exercised; and (f) make such further or other order as to costs or otherwise as the case requires.
“Inquire into the matter” describes a rehearing on the record: the depositions and exhibits forwarded under section 224, the reasons or the section 225 report, and the appeal book compiled under Order 18 of the National Court Rules. Fresh evidence is excluded by section 229 except by consent or order. See fresh evidence on appeal.
The test: substantial miscarriage of justice
An appeal shall be allowed only if it appears to the National Court that there has been a substantial miscarriage of justice.
This is the filter. It is not enough to show that the magistrate made an error; the error must have produced a substantial miscarriage of justice. Two consequences follow. A technical error that did not affect the result will not succeed, and sections 163, 240, 244 and 245 reinforce that by allowing the National Court to amend a conviction where the evidence supported it and to sustain a conviction despite the absence of a summons where the defendant did not object. Conversely, an error that went to the fairness of the hearing, or to the Court’s jurisdiction, will almost always satisfy the test.
What has satisfied the test
| Case | Error | Order |
|---|---|---|
| Kereku v Dodd [1969–70] PNGLR 176 | Unrepresented defendant denied cross-examination and tried jointly without consent | Conviction quashed |
| Philipae v Igaso (2011) N4366 | Eviction order made without service, in breach of s 143 and natural justice | Order quashed; remitted for rehearing |
| Yagon v Nowra (2008) N3375 | Summary ejectment order against occupiers who had a licence | Order quashed |
| Malipu v Laka (2025) N11322 | Dismissal for want of prosecution and consequential orders made without power under s 25 | Decision quashed; remitted to another competent court under s 230(1)(d) |
| Ganta v Nandi [1973] PNGLR 61 | Conviction on a charge that disclosed no offence | Conviction quashed |
| Tiri v Eka (2011) N4507 | No error of fact or law shown | Appeal dismissed: “no miscarriage of justice” |
Choosing the order
Where the record contains all the evidence and the error was in its evaluation or in the law applied, the National Court can substitute the decision that ought to have been made under section 230(1)(c), which ends the matter. Where the error was procedural, so that the evidence was never properly taken, or where the magistrate acted without jurisdiction, the usual order is to quash and remit for rehearing, often before a different magistrate, as in Philipae and Malipu. Section 230(1)(e) also lets the National Court do anything the District Court could have done, such as make an instalment order or a costs order. On a sentence appeal, section 230(1)(b) allows the penalty to be reduced or, on a Public Prosecutor’s appeal under section 219(4), increased.
The curative provisions
Section 244 provides that where on appeal the depositions in substance support the decision, and the decision does not extend beyond the information, the powers of amendment in section 240 may be exercised and a conviction containing some excess may be corrected and stand good for the remainder. Section 163 allows the National Court to amend a conviction or order defective in form or substance where sufficient grounds were in proof. Section 245 sustains a conviction against a defendant who was present and did not object to the want of an information or summons, and section 246 saves a conviction from a wrong distribution of the penalty. These are the provisions that make section 230(2) bite on technical grounds of appeal.
After the decision
Section 233 requires the Registrar to send a memorandum of the National Court’s decision to the Clerk for entry in the register. Section 236 gives the District Court authority to enforce the decision as affirmed, amended or made by the National Court, and protects the magistrate from any action for doing so. Costs are dealt with under sections 234 and 235; see costs of an appeal. The National Court’s decision may itself be appealed to the Supreme Court under the Supreme Court Act, as in Tiri v Eka (2017) SC1586.
Framing the grounds
A ground that says “the magistrate erred in admitting the letter” invites the answer that nothing turned on it. A ground that says “the magistrate admitted the letter without giving the appellant the opportunity to cross-examine its author, and the finding of liability rested on it” identifies the miscarriage. Section 232 allows a defective notice to be amended, but the grounds should be drawn from the outset with section 230(2) in mind.

Before relying on anything here, read the current text of the District Courts Act (Chapter 40) and check for later amendments. The Act is not on PacLII; the figures and time limits quoted in this series come from the consolidation to No 8 of 2000, and the District Courts (Amendment) Act 2009 changes some of them once it is brought into operation.
