Background
Svetlana Barbina was injured in a motor vehicle collision on 3 June 2020 at Bahrs Scrub, Queensland, when her Toyota station wagon was struck by a BMW sedan driven by Bradly Alexander McKenzie. The second respondent, RACQ Insurance Limited, admitted liability for the negligence. The trial, conducted over three days in September 2024 in the District Court at Brisbane, involved a self-represented applicant assisted by a McKenzie friend (her son), who required a Russian interpreter.
The central factual issue was whether the applicant’s lower back injury was a permanent injury caused by the collision or whether her continuing symptoms resulted from a pre-existing arthritic condition. This depended entirely on competing expert orthopaedic evidence. The applicant’s expert, Dr L D King, opined that she suffered an “aggravation of disc bulge L5/S1 level causing right L5 radicular symptoms,” assessing 8% whole-person impairment. The respondents’ expert, Dr David Morgan, concluded the applicant had suffered only a temporary cervical strain with probable age-related degenerative disc changes and 0% impairment.
The primary judge awarded the applicant damages of only $15,320. Because this amount fell below the Magistrates Court jurisdictional limit, leave to appeal was required.
The Court’s Holding
The Court of Appeal refused leave to appeal. The court upheld the trial judge’s preference for Dr Morgan’s expert evidence on three grounds. First, the trial judge reasonably concluded that the L5/S1 disc bulge could not anatomically be compromising the right L5 nerve root because the L5 nerve exits the spinal canal above the disc level; rather, pre-existing facet joint arthritis at the stenosed neural foramen was causing the compression. Second, the applicant’s own medical records from 2006 documented “long standing low back pain,” supporting the pre-existing condition theory. Third, the mechanism of injury (constrained by seatbelts) was unlikely to cause significant lumbar injury, and there was an absence of objective evidence of acute lumbar trauma.
On the applicant’s first ground of appeal—that the trial judge erred in accepting Dr Morgan’s “anatomically impossible” evidence without it being put to Dr King in cross-examination—the court held the rule in Browne v Dunn did not require this. The applicant had notice that the nature of the defendants’ case challenged the causal connection between the disc bulge and nerve compression. Even if a technical breach had occurred, the applicant could have sought to recall Dr King to respond but did not. The trial judge retained discretion to accept the evidence and weigh competing expert opinions.
Key Takeaways
- Trial judges receive substantial appellate deference when preferring expert evidence based on assessments of witness credibility and reliability formed during cross-examination. Appellate courts intervene only if the trial judge has “palpably misused” their advantage or acted on evidence that was “glaringly improbable” or “inconsistent with facts incontrovertibly established.”
- The rule in Browne v Dunn does not require counsel to put every specific point to a witness; it requires only that the opposing party give notice of the nature of their case. If a party is genuinely surprised by evidence during trial, they may seek to recall a witness for further cross-examination rather than appealing after judgment.
- Medical records admitted as business records under the Evidence Act retain their weight as evidence of contemporaneous facts, even when the record maker is not called to testify. The trial judge’s assessment of weight is within their discretion and not easily overturned on appeal.
Why It Matters
This decision reinforces significant procedural and evidentiary hurdles for appellants challenging expert evidence findings. Self-represented parties and their representatives must actively preserve issues at trial through appropriate cross-examination, objections, and requests for witness recall—not rely on appeal to remedy perceived unfairness. The court’s application of appellate restraint reflects the practical reality that trial judges see and hear witnesses and are best positioned to assess credibility, a determination appellate courts cannot easily second-guess from a transcript.
For personal injury practitioners, the case underscores that competing medical evidence will be resolved at trial based on the trial judge’s assessment of expert reliability, and appellate review of such findings is highly deferential. The judgment also confirms that contemporaneous medical records documenting a plaintiff’s own statements (such as reporting longstanding pain) carry significant evidentiary weight in causation disputes, even without expert elaboration from the treating practitioner.
