9. McHugh J in Everett v The Queen [(1994) [1994] HCA 49; 181 CLR 295 at 306], referred to the role of prosecution appeals when "a sentencing judge imposes a sentence that is definitely below the range of sentences appropriate for the particular offence". Whether one talks in terms of a range of appropriate sentences or, like Canadian courts, in terms of a starting-point for consideration, appellate courts, both for the purpose of making and explaining their own decisions, and for the guidance of primary judges, may find it useful to refer to information about sentences that have been imposed in comparable cases, and to indicate, subject to relevant discretionary considerations, the order of the sentence that might be expected to be attracted by a certain type of offender who commits a certain type of offence. In some jurisdictions, such as the United Kingdom, this has been undertaken more often, and with greater specificity, than in others. But it has also been done in Canada [R v McDonnell [1997] 1 SCR 948], Hong Kong [Chan Chi-ming v The Queen [1979] HKLR 491], and New Zealand [R v N [1998] 2 NZLR 272]. In 1992 the Council of Ministers of the Council of Europe approved recommendations concerning sentencing consistency, which included reference to guidelines judgments by superior courts when that is appropriate to the constitution or the traditions of the relevant legal system [Council of Europe, Recommendation No R (92), 17, Consistency of Sentencing (Strasbourg, 1993)]. In some jurisdictions there is statutory backing for the practice; in others there is not. The history of the practice, with particular reference to what had been done in the past in New South Wales, and the reasons for recent developments in that jurisdiction, may be seen in the judgment of Spigelman CJ in R v Jurisic [(1998) [1998] NSWSC 423; 45 NSWLR 209.
