INTRODUCTION
22 The classifications provide a framework for classifying criminal court information for statistical purposes, promoting data that are compiled on a consistent basis across states and territories. The classifications allow for different levels of detail to be recorded depending on the level of detail in the source information. Associated with each classification are coding rules which ensure that the counting of information is consistent across states and territories. COUNTING METHODOLOGY Transfer between Higher Court levels 23 Defendants who transfer from one Higher Court level to another are considered as initiated only once (in the level they first entered) and finalised only once (from the level they finally left). Transfer between Magistrates' and Higher Court levels 24 Defendants who transfer from the Magistrates' Court level to the Higher Court level are considered as initiated twice (once in each of these levels) and finalised twice (once in each level). Defendants may have some charges finalised in the Magistrates' Courts whilst other charges are committed to the Higher Courts. A defendant in this situation would be counted in the Magistrates' Courts data and the Higher Courts data. Method of finalisation 25 Method of finalisation describes how a criminal charge is concluded by a criminal court level. For the purposes of the Criminal Courts collection, one method of finalisation is applied to each defendant within the Magistrates' Courts and each defendant within the Higher Courts. 26 As part of the original ABS Higher courts collection, a bench warrant issued was considered a method of finalisation. From the 2002-03 reference period, this is no longer considered a method of finalisation for a defendant in the Higher Courts. This aligns with the Magistrates' Courts which do not include a bench warrant issued as a method of finalisation. 27 Defendants who are referred to a Mental Health Review Tribunal (e.g. for determination of fitness for trial) are not considered to be finalised. Higher Courts 28 Where a defendant finalised in a Higher Court has multiple charges and these have different methods of finalisation, the defendant method of finalisation code is determined by the following order of precedence:
Magistrates' Courts 29 Where a defendant finalised in a Magistrates' Court has multiple charges and these have different methods of finalisation, the defendant method of finalisation code is determined by the following order of precedence:
Merging counting units 30 Where a person or organisation is a defendant in more than one case, and their cases are finalised on the same date, in the same court level and in the same court location, their defendant records will be merged and counted as a single defendant record. This merging rule is used for defendants finalised in both the Higher and Magistrates' Courts. Principal offence adjudicated 31 Principal offence is only calculated for adjudicated defendants. Charges considered for the purpose of determining the principal offence are only those charges that have an adjudicated method of finalisation (i.e. where the defendant has pleaded guilty or the court has made a decision as to whether or not the defendant is guilty). Thus, charges that have been transferred to another level of court, together with those that are withdrawn or dealt with by some other non-adjudicated method, are not considered for the purposes of determining the principal offence adjudicated. 32 For a defendant who has a method of finalisation of proven guilty (resulting from a guilty verdict, guilty plea or guilty ex-parte), the principal offence is selected from the charge(s) proven guilty (i.e. acquitted charges are not considered). For a defendant who has a method of finalisation of acquitted, the principal offence is selected from the charge(s) acquitted. 33 Where a defendant has a single proven guilty or acquitted charge, the principal offence is the relevant ASOC code (see paragraphs 35-36) associated with the adjudicated charge. 34 Where a defendant has a method of finalisation of proven guilty with multiple charges proven guilty, or where a defendant has a method of finalisation of acquitted with multiple charges acquitted, the principal offence is selected by applying the National Offence Index (see paragraph 37) to these charges. The principal offence is determined as the adjudicated charge with the highest ranked ASOC Group in the Index. Where the defendant has an adjudicated charge but is unable to receive an Index ranking (due to missing offence information or the offence mapped to an ASOC code is not included in the Index) the principal offence is coded to 'not able to be determined'. Australian Standard Offence Classification (ASOC) 35 The ASOC was developed by the ABS for use in the collection and publication of crime and justice statistics. It provides a uniform national classificatory framework for the compilation and comparison of statistics on offences across Australia. 36 Offence data have been coded to the ASOC on the basis of mappings of state/territory legislative codes undertaken by various agencies within those states and territories. The ABS has not undertaken any systematic checks to assess the quality of the ASOC coding for the charges adjudicated in the Criminal Courts. Amendments to the ASOC codes have only been made in very limited cases where erroneous codes were identified as part of the edit checks applied to the final data. National Offence Index (NOI) 37 The National Offence Index (see Appendix 3) is a ranking of all ASOC Groups and selected supplementary ASOC codes (ASOC Divisions and/or ASOC Subdivisions). This ranking is based on the concept of seriousness, with a ranking of 1 relating to the ASOC code containing the most serious offence. In developing this Index, the ranking of offences was analysed using the 2000-01 Higher Courts data. The results indicated that the Index produced principal offence output that aligned with that produced using the 2000-01 Principal Offence rules which were based on actual sentences handed down in the Higher Courts in the 2000-01 reference period. In addition, the Index resulted in significant data quality improvements with the proportion of adjudicated defendants for whom a principal offence was unable to be determined reducing from a national average of 17% in 2000-01 to 3% in 2001-02 using the Index. 38 The assumptions and rules underpinning the NOI, in particular defining 'offence seriousness' and the subsequent impact of this definition on the ranking of offences, need to be considered when using the principal offence data in this publication. However, it is important to note that these technical issues are only of practical significance where a choice must be made between output categories (see paragraph 39). For example, although some Sexual assault and related offences are ranked ahead of Illicit drug and related offences, they are unlikely to co-occur. For further information regarding the development of the NOI please refer to Appendix 5 in Criminal Courts, Australia, 2001-02 (cat. no. 4513.0). 39 The principal offence for each adjudicated defendant (i.e. acquitted or proven guilty) is aggregated and published at the ASOC Division level for selected tables, and at the more detailed ASOC Subdivision or Group level (including the ASOC Group of Breach of domestic violence orders) for other tables. Principal sentence 40 Within this publication, defendants who are proven guilty have sentence information reported against them at the defendant level. This is usually, though not necessarily, the sentence associated with the principal offence. A defendant can receive a single sentence for a single offence proven guilty, a single sentence for multiple offences proven guilty, multiple sentences for multiple offences proven guilty and/or multiple sentences assigned to the one offence proven guilty. Where a defendant has multiple sentences, the principal sentence is selected by applying the hierarchy of the Sentence Type Classification (see Appendix 4). DATA COMPARABILITY 41 The Criminal Courts collection has been designed to facilitate comparisons of states and territories through the application of common national statistical standards. However, some legislative and processing differences may limit the degree to which the statistics are comparable across the states and territories. Differences may also arise as a result of other factors, including refinements in data quality procedures and modifications in the systems used to obtain and compile the figures. 42 To ensure that the statistics are as reliable as possible, the ABS has employed a number of measures. A range of edit checks identify any erroneous data and these are queried and resolved by the ABS in consultation with the relevant state or territory representative. The final data are also checked against other available data sources, such as state and territory court statistics and annual reports produced by the court administration agencies and the Offices of the Directors of Public Prosecutions. 43 Data quality control checks will continue to be reviewed and modified as the Criminal Courts collection evolves. Data availability and quality will also improve as the states and territories further develop and improve their court operational systems. CONFIDENTIALITY OF TABULAR DATA 44 A technique has been implemented to avoid identification of individuals. The confidentiality technique applied by the ABS is to randomly adjust cells with very small values. These adjustments do not impair the value of the table as a whole. 45 Tables which have been randomly adjusted will be internally consistent however, comparisons with other tables containing similar data may show minor discrepancies. These small variances can, for the most part, be ignored. RELATED PUBLICATIONS ABS publications 46 ABS publications which may be of interest include:
