Factual and Procedural Background
The Appellant, a mathematics teacher, was convicted after trial of sexual offences against two school pupils, who were related as uncle and nephew. The Crown relied on the Moorov doctrine for conviction despite a temporal gap of nearly 17 years between the offences. The Appellant appealed on grounds including that the trial judge erred in rejecting a no case to answer submission due to insufficient evidence of a course of conduct, and that the judge’s directions on the Moorov doctrine were inadequate. The appeal also challenged the six-year prison sentence.
The trial evidence detailed inappropriate conduct by the Appellant towards the first complainer during secondary school, including sexualised conversations, massages with inappropriate touching, and sexual acts involving gifts and outings. Similar conduct was described with the second complainer, the nephew, who had known the Appellant all his life but was not his pupil. The Appellant provided tutoring, took the second complainer to the gym under false pretences, gave massages, and engaged in sexual acts accompanied by gifts and outings. The trial judge ruled that the incidents were strikingly similar enough for the Moorov doctrine to apply and repelled the no case to answer submission.
Legal Issues Presented
- Whether the trial judge erred in rejecting the no case to answer submission due to insufficient evidence that the offences formed part of a single course of conduct under the Moorov doctrine.
- Whether the trial judge’s directions to the jury adequately emphasised the necessity for strikingly compelling similarities when applying the Moorov doctrine to incidents separated by a significant time gap.
- Whether, given the absence of evidence of compelling similarities, no reasonable jury could have convicted.
- Whether the sentence of six years’ imprisonment was appropriate.
Arguments of the Parties
Appellant's Arguments
- Accepted no fixed upper time limit for applying the Moorov doctrine but argued the 17-year gap required extraordinary or striking similarities to link the offences as a course of conduct.
- Asserted that the similarities were conventional and not extraordinary, with significant differences between charges.
- Contended there was no evidence that the Appellant lacked opportunity to commit other offences in the intervening period.
- Rejected the “generational” explanation for the gap, noting no evidence of grooming or a deliberate relationship with the family to facilitate offences.
- Maintained that the similarities did not support an inference of a systematically pursued course of conduct.
Respondent's Arguments
- Emphasised the importance of the family relationship, particularly in relation to the second complainer who had known the Appellant all his life.
- Presented the offences as part of a campaign where the Appellant, having abused the first complainer without detection, targeted other family members.
- Highlighted that the Appellant’s relationship with the second complainer was facilitated by family friendship and tutoring, enabling greater access.
- Noted the Appellant’s apparent attraction to adolescent boys and the relevance of his role as a maths teacher in secondary school to his opportunity to offend.

Court's Reasoning and Analysis
The court undertook a detailed examination of the Moorov doctrine, emphasizing the necessity for an underlying unity of intent to establish that multiple offences form part of a “course of conduct systematically pursued” by the accused. It reiterated that no fixed maximum time interval precludes application of the doctrine, but the probative value of a significant time gap depends on case circumstances.
The court reviewed authoritative statements from Moorov and subsequent cases, noting that mere superficial similarities in time, character, and circumstance are insufficient. Instead, the evidence must support an inference of a connected, underlying intent or project.
Applying these principles, the court considered the 17-year gap between offences and the nature of the relationship between the Appellant and the complainers. It found that the family relationship was incidental rather than a factor facilitating a continuous course of conduct. The Appellant’s conduct towards the first complainer was not linked to the wider family, and the second complainer’s contact with the Appellant predated the misconduct but did not involve abuse until after commencing secondary school.
The court concluded that the similarities between offences were conventional and insufficiently striking or extraordinary to bridge the lengthy interval. There was no evidence suggesting a singular, persistent course of conduct directed at the family or otherwise. Instead, the evidence indicated two separate courses of conduct arising from the Appellant’s disposition, rather than a unified criminal campaign.
Given the caution required when applying the Moorov doctrine to cases with few complainers and long time gaps, the court determined that the issue should not have been left to the jury, and the no case to answer submission should have been upheld.
Holding and Implications
The court ALLOWED THE APPEAL against conviction, concluding that the evidence was insufficient to establish a course of conduct linking the two charges under the Moorov doctrine given the significant time gap and lack of extraordinary similarities.
This decision results in the quashing of the convictions. The court did not set new precedent but reaffirmed the strict application of the Moorov doctrine, particularly emphasizing caution when dealing with limited complainers and substantial intervals between offences. The ruling underscores the necessity for compelling evidence of an underlying unity of intent to link offences as a course of conduct.
