Citation: [2026] NSWDC 121
Court: District Court of New South Wales
Date: 1 May 2026
Judge(s): Newlinds SC DCJ
Background
The offender, referred to by the pseudonym MB, pleaded guilty to a charge of break, enter and commit serious indictable offence (robbery) under s 112(2) of the Crimes Act 1900 (NSW). The offence carries a maximum penalty of 20 years' imprisonment and a standard non-parole period of five years.
On 3 October 2024, MB and his co-offender MA drove from Sydney to far western New South Wales in a borrowed van, entered the home of a 78-year-old victim living alone, assaulted him, tied him up, ransacked his house, and stole $100,000 in cash. They left the victim tied up with no apparent ability to free himself. MA, a serving police officer, had identified the victim and the location of his money by misusing confidential information obtained through his role.
MA had previously been sentenced to 10 years' imprisonment with a six-year non-parole period. The present sentencing of MB required the Court to assess his comparative objective seriousness and consider the principle of parity.
Legal Issues
- What was the objective seriousness of MB's involvement in the offence compared to MA's?
- What weight should be given to MB's reduced moral culpability arising from mental health conditions and vulnerability to MA's influence?
- Whether aggravating factors under s 21A of the Crimes (Sentencing Procedure) Act 1999 (NSW) applied, including the victim's age, gratuitous violence, significant planning, and harm caused by social media reaction.
- Whether an analogy to equitable principles (knowing involvement in breach of trust equating to the position of a defaulting trustee) was appropriate for determining MB's level of culpability.
- Whether the principle of parity required a substantially different sentence from that imposed on MA, given differing roles and subjective circumstances.
Decision
The Court found that MB's role in the crime was significantly less than MA's. MA had instigated and planned the offence, sourced the confidential information through a gross breach of his duties as a police officer, and committed most of the violence. MB, however, knew the source of the information, was content to participate, was present during some of the violence, and jointly decided to leave the elderly victim tied up alone.
The Court accepted expert psychological evidence that MB suffered from longstanding untreated ADHD, complex trauma (rooted in childhood physical and sexual abuse, unresolved grief, and a 2022 head injury), and a characteristic susceptibility to over-trust and affiliate out of loyalty rather than independent judgment. These factors were found to have reduced MB's moral culpability by increasing his susceptibility to MA's influence, though they did not remove his responsibility.
The Crown's submission that the offending was above mid-range seriousness was rejected. The Court assessed MB's offending as slightly beneath the mid-range of seriousness and materially less serious than MA's. The Court explicitly rejected the proposition that equitable concepts from Barnes v Addy and related authorities (where a person knowingly involved in a breach of trust is treated as a defaulting trustee) should be transposed into sentencing to equate MB's culpability with MA's. The Court treated as an aggravating factor the harm caused to the victim by social media reaction to the crime, finding this went over and above the harm ordinarily expected.
On parity, the Court concluded that the substantial differences in both involvement in the crime and subjective circumstances between MA and MB justified a significant disparity in their sentences.
Orders Made
- MB was sentenced to a term of full-time imprisonment (the specific term is not set out in the truncated text, but was materially less than MA's 10-year sentence).
- The sentence was backdated to account for 1 month and 25 days of pre-sentence custody (from 24 October 2024 to 17 December 2024).
- MB received the full 25% utilitarian discount for his early guilty plea at the first available opportunity.
Key Takeaways
- The District Court held that MB's objective criminality was materially less serious than MA's, principally because MA, as a serving police officer, sourced and misused confidential information to identify the victim, instigated and planned the crime, and committed most of the violence.
- Equitable principles treating a person knowingly involved in a breach of trust as equivalent to the defaulting trustee (per Barnes v Addy) were found to be inappropriate analogies for assessing relative culpability in sentencing.
- Expert psychological evidence established a nexus between MB's untreated ADHD, complex trauma, and head injury and his susceptibility to being influenced by MA, which the Court accepted as reducing his moral culpability without removing his responsibility.
- Harm to the victim caused by social media reaction to the crime was treated as an aggravating factor on the basis that it exceeded the harm ordinarily expected from offending of this type.
- In applying the principle of parity, the Court determined that a substantially different sentence was justified where both the offenders' roles in the crime and their subjective circumstances differed significantly.
