Background
Matthew Francis Olssen was convicted on 21 October 2016 after jury trial of trafficking in methylamphetamine (count 1), possession of methylamphetamine exceeding 200 grams (count 2), and supply of methylamphetamine to another person (count 3). He was sentenced to nine years’ imprisonment on count 1, with parole eligibility after six-and-a-half years. His first appeal was dismissed in 2018 (R v Olssen [2018] QCA 114).
The prosecution’s case relied heavily on telephone intercepts allegedly involving Olssen arranging three drug transactions. Olssen did not give evidence at trial. The trial proceeded on admissions concerning flights, movements, and phone records, with only two prosecution witnesses called: a detective and Stuart Grainger, a courier who flew to Brisbane to collect drugs concealed in a massage machine and deliver them to Peter Heilbronn.
Olssen subsequently applied for leave to make a subsequent appeal under s 671AC(2) of the Criminal Code (Qld), asserting multiple grounds based on allegedly “new and compelling evidence,” including discrepancies about whether the massage machine contained methylamphetamine or pseudoephedrine, voice identification issues on telephone intercepts, and inconsistencies in witness statements and transcript records.
The Court’s Holding
The Court of Appeal (Mullins P, Brown JA, Henry J) refused the application for leave to make a subsequent appeal. The court held that none of the grounds satisfied the statutory test for “new and compelling evidence” under s 671AB(4) and (6) of the Criminal Code (Qld).
On the primary ground—that the prosecution alleged methylamphetamine in the massage machine at trial but asserted pseudoephedrine at a co-defendant’s sentencing—the court found this was not new evidence. Olssen’s trial lawyers were aware of this discrepancy at the time of trial and relied upon it to argue reasonable doubt. No estoppel or issue estoppel in criminal law prevents the prosecution from taking different positions in separate proceedings. The voice identification claim amounted to re-litigating evidence heard at trial rather than advancing new evidence, particularly where Olssen had made a strategic decision not to give evidence. Similarly, the witness statement inconsistencies and alleged prosecutorial misrepresentation were known to trial counsel and used at trial.
Regarding transcript discrepancies in a telephone recording (Barton 1 [313])—where pages in the appeal record differed from pages in a brief provided to Olssen—the court refused leave for Olssen to rely on expert evidence from a document examiner. The court held that the jury heard the actual audio recording, not the transcript. Despite discrepancies in the written record, the content of the audio actually played to the jury remained indisputable. Leave was granted for the respondent to file an affidavit explaining that original audio discs could not be located after exhibits were returned to police following the first appeal.
Key Takeaways
- To succeed on a subsequent appeal, evidence must be genuinely “new”—not evidence known to trial counsel or issues available at first appeal but not pursued.
- Strategic trial decisions (such as an accused not giving evidence) cannot be revisited on subsequent appeal by asserting contradictory claims about voice identification or other evidence heard by the jury.
- Prosecutorial assertions in separate proceedings (e.g., a co-accused’s sentencing) do not create estoppels preventing alternative positions at trial.
- Transcript errors or discrepancies do not overturn a verdict when the actual audio evidence heard by the jury is not in dispute.
Why It Matters
This decision reinforces the narrow scope of subsequent appeals in Queensland criminal law. The threshold for “new and compelling evidence” is high: evidence must not only be new but also compelling and must satisfy statutory criteria. Courts will not permit applicants to re-litigate trial evidence under the guise of a subsequent appeal, nor will they treat evidence known to trial counsel as “new” simply because it was not fully exploited at first appeal. This protects finality in criminal proceedings while preserving genuine review for miscarriages of justice based on evidence truly unavailable at trial.
The judgment also clarifies that while procedural inconsistencies in prosecution case-building may be notable, they do not constitute new evidence when trial counsel were aware of and engaged with those inconsistencies. The court’s refusal to consider expert evidence about transcript discrepancies, combined with its confirmation that the actual audio heard by jurors governs the verdict, underscores that form-level errors in trial administration do not displace substantive evidence.
