35 The principles applicable by this Court are well known and have been stated on many occasions. They were summarised by Wood CJ at CL in a much cited paragraph in R v Wall [2002] NSW CCA 42, which is cited in full in R v Prasad (2004) 147 A Crim R 385 at [27] in the following terms:
"(a) The normal restriction upon appellate review of the exercise of a discretion, as set out in House v The King (1936) 55 CLR 499, applies to Crown appeals against sentence: Dinsdale v The Queen (2000) 202 CLR 321; with the result that this Court cannot merely substitute its opinion, as to the appropriate sentence, for that of the sentencing judge: Lowndes v The Queen (1999) 195 CLR 665 at 671; rather, it may interfere only where error either latent or patent is shown; R v Tait (1979) 46 FLR 386 at 388; and Wong and Leung v The Queen (2001) 207 CLR 584; 76 ALJR 79 at [58] and [109].
(b) Appeals by the Crown should generally be rare; Malvaso v The Queen (1989) 168 CLR 227 at 234, and unless there is a clear error of principle identified, it would be exceptional for the Court to interfere: R v Baker [2000] NSWCCA 85.
(c) A Crown appeal against sentence is concerned with establishing matters of principle 'for the governance and guidance of courts having the duty of sentencing convicted persons': per Barwick CJ in Griffiths v The Queen (1977) 137 CLR 293 but this power extends to doing what is necessary to avoid manifest inadequacy or inconsistency in sentencing, that is, where the sentence is definitely outside the appropriate range for the case in hand: Everett v The Queen (1994) 181 CLR 295 at 299, 74 A Crim R 241 at 244; Dinsdale v The Queen (2000) 202 CLR 321, 115 A Crim R 558, and Wong and Leung v The Queen .
(d) The Court has a lively discretion to refuse to intervene even if error has been shown, and in deciding whether to exercise that discretion, it should have regard to the double jeopardy that a convicted person faces as a result of a Crown appeal: R v Allpass (1993) 72 A Crim R 561, Director of Public Prosecutions v Papazisis (1991) 51 A Crim R 242 at 247, and Wong and Leung v The Queen at [110].
(e) A sentence which is imposed as a consequence of a successful Crown appeal will generally be less than that which should have been imposed by the sentencing court: R v Holder and Johnston (1983) 3 NSWLR 245 at 256, and will generally be towards the lower end of the available range of sentence: Dinsdale v The Queen at para [62]."
36 I have previously stated that to that summary should be added the statement in Dinsdale, supra, concerning the Court's "strong resistance" to tinkering with sentences and the injunction to appellate courts in the joint judgments of Gummow, Callinan and Heydon JJ in Johnson v The Queen (2004) 78 ALJR 616 at [26].
