R v Leighton

[2017] NSWDC 472

Sexual offences
CRIME

Citation: R v Leighton [2017] NSWDC 472
Court: District Court of New South Wales
Date: 24 July 2017
Judge(s): C Craigie SC DCJ

Background

The offender, a retired dentist, pleaded guilty to a total of 16 counts across two indictments, with additional matters taken into account on three Form 1 documents. All of the offending occurred between 1974 and 1983, during which the offender sexually assaulted patients at his dental practice while they were at least partially incapacitated by nitrous oxide gas he had administered under the guise of legitimate dental treatment.

The victims named across the two indictments included five female children aged between approximately 10 and 14, and three adult women. The offending was opportunistic and predatory, exploiting the offender's position of professional authority and trust. The matters came before the District Court following an earlier trial at which the offender had already been convicted and sentenced for related offending against a separate group of child patients from the same period.

At the time of sentencing, the offender was in advanced age and declining health. More than 40 years had passed since the earliest offending, during which time he had faced no criminal consequences and continued to enjoy the professional and social standing of a practising dentist.

  • Which sentencing framework and practices applied to offences predating the Crimes (Sentencing Procedure) Act 1989 (NSW)?
  • What maximum penalties and sentencing ranges governed the relevant offences as charged under the Crimes Act 1900 (NSW) in its form at the time of the conduct?
  • How should the court treat the significant delay between the offending and sentencing, including its effect on the offender's age and health?
  • What discount, if any, applied to the guilty pleas across both indictments?
  • How should the aggregate sentence interact with the sentence already imposed following the earlier trial?

Decision

The court confirmed that it was bound to sentence the offender according to the sentencing practices, tariffs, and maximum penalties that applied at the time of the offending in the 1970s and early 1980s, not those that apply today. This obligation flows from a strong body of appellate authority, including the High Court's decision in Power v The Queen (1974) 131 CLR 623. The court acknowledged that those historical sentencing ranges are now widely regarded as manifestly inadequate by contemporary legislative and judicial standards, but noted that it had no discretion to depart from them.

The court also addressed the consequences of the long delay. The offender's advanced age and sharply declining health were mitigating factors the court was required to take into account, even though that delay was attributable entirely to the offender's exploitation of his victims' vulnerability and the social conditions of the time that discouraged complaint. The court observed that full justice for the victims was ultimately impossible to achieve given the constraints imposed by historical sentencing practice.

A discount of 25% was applied to the three counts on the first indictment where pleas had been entered before a magistrate at the earliest opportunity. A lesser discount applied to the remaining counts, where the pleas came later. The resulting aggregate sentence was partially accumulated on the earlier sentence already being served.

Orders Made

  • An aggregate sentence of eight years imprisonment was imposed, with a non-parole period of three years.
  • The sentence commenced on 11 March 2016 (partially accumulated on the earlier sentence), with the non-parole period expiring on 10 March 2019.
  • Indicated individual sentences were recorded for each count across both indictments, ranging from six months to two years and nine months.

Key Takeaways

  • Where offences predate the Crimes (Sentencing Procedure) Act 1989 (NSW), a sentencing court is bound to apply the sentencing practices, tariffs, and maximum penalties in force at the time of the offending, even where those practices are now considered inadequate.
  • A conviction for historical sexual offences does not permit departure from the era-appropriate sentencing framework merely because current standards would produce a more severe outcome; the obligation to apply historical practices is confirmed by the High Court in Power v The Queen.
  • Significant delay between offending and sentencing can operate as a mitigating factor where it has contributed to the offender's advanced age and declining health at the time of sentence, even in cases of serious and repeated predatory conduct.
  • The District Court distinguished between guilty pleas entered at the earliest opportunity (attracting a 25% discount) and those entered at a later stage, with the latter attracting a lesser reduction.
  • Victims of historical sexual offending may not receive the full measure of justice that contemporaneous prosecution would have produced, a consequence the court described as regrettable but legally compelled by the requirement to sentence according to historical practices.
