Ground 5: De Simoni and the first offence
33At the hearing of the appeal, Counsel for the applicant, Ms Francis, sought leave to add a further ground to her client's notice of appeal. The Crown did not object and leave was granted. It is convenient to deal with it first. The additional ground alleged that the sentencing judge erred by sentencing the applicant in respect of the first offence on the basis of facts which give rise to the more serious offence of intending to pervert the course of justice.
34As noted, this ground seeks to invoke the "principle" in De Simoni. In De Simoni the offender pleaded guilty to a charge under s 391 of the Criminal Code (WA) of robbery. An element of that offence was that he had used "actual violence" (at 387). In fact, during the robbery he had struck his victim a heavy blow on the back of the head inflicting a wound at the rear of the skull (at 386). There was an aggravated version of the offence under s 393 of the Criminal Code (WA) if a robbery involved, inter alia, "wound[ing]" or "personal violence" (at 387). The Western Australian Court of Criminal Appeal had held that the sentencing judge had impermissibly sentenced the offender on the basis that he wounded the victim and allowed his appeal from the sentence. The High Court restored the sentence on the basis that that characterisation of the sentencing judge's approach was itself erroneous, and the sentencing judge had relied on no more than the fact that the offender "used violence" (at 394 per Gibbs CJ).
35Chief Justice Gibbs (with whom Mason and Murphy JJ agreed) articulated the general principle for which De Simoni stands as follows (at 389):
"... a judge, in imposing sentence, is entitled to consider all the conduct of the accused, including that which would aggravate the offence, but cannot take into account circumstances of aggravation which would have warranted a conviction for a more serious offence."
36However, later in the judgment Gibbs CJ addressed the position where the circumstance of aggravation is also an element of the offence for which the offender is being sentenced (at 393 to 394):
"The application of s 582 leads to difficulty in some cases of robbery. Under s 391, it is an element of the offence that the offender has used or threatened to use actual violence to any person or property. Under s 393 a circumstance of aggravation is that the offender wounds or uses any other personal violence to any person. In my opinion there is no difference between using actual violence to any person, and using personal violence to any person. Actual violence means no more than physical force which is real and not merely threatened or contemplated. Personal violence means violence to the person - bodily violence. Under s 391 the relevant element of the offence may be satisfied by actual violence to property or by threatened violence to the person, and in those cases there will not necessarily exist any circumstance of aggravation. However, the necessary element required by s 391 may also be satisfied by actual violence to any person, and where that is the case the element of the simple offence will also constitute a circumstance of aggravation. ...
If an offender has been convicted of robbery, and the indictment charges that he used actual violence to any person, it is obvious that the trial judge, in imposing sentence, may have regard to the actual violence that was used, notwithstanding that it would also constitute personal violence within s 393. On the other hand, if the actual violence used resulted in wounding, the trial judge should not take the wounding into account unless it has been charged in the indictment, for the wounding is purely a circumstance of aggravation and not an element of robbery simpliciter." (emphasis added)
37This passage reveals the subtleties that can be involved in the application of De Simoni (see McCullough v R [2009] NSWCCA 94; 194 A Crim R 439 at [38]-[39] per Howie J, McClellan CJ at CL and Simpson J agreeing; and Einfeld v R [2010] NSWCCA 87; 200 A Crim R 1 at [135]-[138]). Nevertheless, the emphasised passage in [36] makes it clear, as does the outcome in De Simoni, that the sentencing process will not miscarry if the sentencing proceeds upon facts that merely satisfy the elements of the offence charged, even if one of those elements can amount to a circumstance of aggravation sufficient to found guilt for another more serious offence. However the sentencing process may miscarry if those facts amount to such a circumstance which is not an element of the offence charged.
38The difficulties in the application of De Simoni arise in this case. Ms Francis argued that the findings made by the sentencing judge in relation to the first offence would have warranted his conviction for the more serious offence of pervert the course of justice found under s 319 of the Crimes Act 1900 and were thus inconsistent with De Simoni.
39Sections 311, 312, 317 and 319 of the Crimes Act 1900 relevantly provide:
"311 Definitions
(1) In this Part:
benefit means any benefit or advantage whether or not in money or money's worth.
judicial officer means a person who is, or who alone or with others constitutes, a judicial tribunal and includes a coroner.

...
317 Tampering etc with evidence

(a) suppresses, conceals, destroys, alters or falsifies anything knowing that it is or may be required as evidence in any judicial proceeding, or
(b) fabricates false evidence (other than by perjury or suborning perjury), or
(c) knowingly makes use of fabricated false evidence,
is liable to imprisonment for 10 years.
...
319 General offence of perverting the course of justice
A person who does any act, or makes any omission, intending in any way to pervert the course of justice, is liable to imprisonment for 14 years."
40It is unnecessary to undertake a detailed exegesis concerning the differences between s 317 and s 319. There can be no doubt that many cases that satisfy s 317 may also constitute an offence under s 319. It follows from the emphasised passage from De Simoni set out above that it is permissible to merely sentence an offender on the basis of facts that meet the elements of an offence under s 317, even if those facts might also constitute an offence under s 319. However if the factual findings go beyond those elements, then the principle in De Simoni may be engaged.
41An example of a case in this area of discourse that involved an infringement of the principle in De Simoni was referred to in argument, namely R v Mobbs [2005] NSWCCA 371 ("Mobbs"). In Mobbs the offender pleaded guilty to one charge of hindering the investigation of a serious indictable offence contrary to s 315(1)(a) of the Crimes Act 1900 in that he falsely told police that he was the driver of a vehicle involved in a serious car accident. The maximum penalty for the offence was seven years imprisonment. This Court held that a finding by the sentencing judge, that but for the false statement another person would have been prosecuted for the offence, was one that "move[d] beyond the elements of a s 315 offence to a s 319 offence so as to infringe the De Simoni principle" (at [32] per Johnson J, with whom Simpson and Adams JJ agreed).
42In this case when addressing the circumstances of the first offence in this case the sentencing judge stated:
"The offender took a number of steps over a significant period of time to destroy pieces of evidence knowing that they would be required as evidence in judicial proceedings. He sought to take advantage of the difficulties police were under in gaining entry to the property.
No judicial proceedings were underway at the time. Police came upon the offender by chance.
The acts of the accused were clearly deliberate. It is difficult to know to what extent the burning of the items of equipment and chemicals hampered the investigations of police, as it would appear that items were totally destroyed by the fire.
The acts were clearly designed to frustrate proceedings in relation to significant criminal activity relating to the preparations for the manufacture of prohibited drugs." (emphasis added)
43Ms Francis took particular objection to the word "frustrate" in this passage. It was contended that this reference amounted to a finding that the applicant intended to "prevent" successful proceedings relating to the preparations for the manufacture of prohibited drugs. It was submitted that this went beyond the admission of the elements of the offence by the applicant. It was submitted that he was only to be sentenced for "destroying" certain unidentified objects "with the coincident intent of misleading a judicial officer, that is, with the intent of engendering in the judicial officer the wrong impression".
44The Crown submitted that, although it was unclear, this aspect of the sentencing judgment was no more than a restatement of the elements of the offence under s 317. Otherwise it was implicit in both sets of submissions that the form of judicial proceeding contemplated by the first offence is a criminal prosecution concerning the manufacture or attempted manufacture of prohibited drugs.
45While it is unclear, in my view the reference to "frustrate" proceeding in the above passage from the sentencing judgment is no more than a restatement of the elements of the offence under s 317 to which the applicant had pleaded guilty. Properly construed, it does not convey that the applicant destroyed the items while possessing a mental element beyond that specified in s 317. It is notable that in the passage from the sentencing judgment noted in [42] his Honour did not refer to the applicant's intention to mislead the judicial tribunal. This suggests that his Honour was referring to that intention in describing the applicant's acts as clearly intended to "frustrate" proceedings.
46By entering a plea of guilty to an offence under s 317 the applicant admitted that firstly he destroyed objects, secondly that he did so knowing that they were or may be required in a judicial proceeding, and thirdly that he did so with an intention to mislead a judicial tribunal in that judicial proceeding. In my view it is not inaccurate to describe those three elements, without more, as amounting to the undertaking of acts "designed to frustrate" those judicial proceedings. To deny a judicial tribunal items that may be "required as evidence" is to "frustrate" that body in the performance of its function, even if it is not ultimately precluded from performing it. Thus, even if one accepts Ms Francis' characterisation of the relevant intent required to commit an offence under s 317 (noted in [43] above), an intention to engender in a judicial officer the "wrong impression" involves an attempt to frustrate the proper performance of that judicial officer's function.
47Accordingly I reject ground 5.
