Understanding case citations

Case citations

The term 'case citation' can refer to the full Australian Guide to Legal Citation reference for a case (eg Mabo v Queensland [No 2] (1992) 175 CLR 1) or just the citation details component i.e. (1992) 175 CLR 1. This section uses the latter version.

 

Each case is assigned a unique citation, or reference. A significant decision may have parallel (multiple) citations if it has been published in several law report series and/or it is available via AustLII or the relevant court’s website.

A source referring to a case, such as a textbook, usually includes the citation. A case's citation/s can also be found by searching with the case/party names in Lexis+ Australia or Westlaw Australia. This is best practice to confirm the most authoritative version of the case. Note that the BC number in Lexis+ Australia is their internal numbering system, not a case citation.

Interpreting case citations

Interpreting case citations

The ability to interpret case citations assists with locating full judgments efficiently and with citing cases correctly. The format and elements of case citations vary depending on where the case has been published.

Types of case citations

The abbreviation within a reported case citation represents the law report series the case is published in. These citations have round or square brackets around the year. Refer to the Australian Guide to Legal Citation rule 2.2 for further explanation.

 

Round brackets (parentheses)

A year enclosed by parentheses signifies:

  • the year the judgment was handed down, not necessarily the year it was published in that report series
  • the law report series is organised by unique numerical volume numbers, rather than by year.

The case below is reported in volume 101 of the Commonwealth Law Reports, starting on page 298. Click on the blue symbols for a brief description of each citation element.

 

Square brackets [  ]

A year enclosed by square brackets indicates:

  • the year the judgment was published, not necessarily handed down, as publication can take months or even years
  • the law report series is organised by year. A volume number appears after the year if more than one volume of case reports was published in that year.

The case below is reported in 1993 volume 1 of the Queensland Reports series, starting on page 100. Note that the abbreviation for the Queensland Reports recently changed to QR. Click on the blue symbols for a brief description of each citation element.

Remember that an unreported version of a case should only be used if the case has not been reported in a law report series. Consult a case law research product if you're unsure whether a reported version exists.

Medium neutral citations

The case citation contains a court abbreviation.

Recent cases, or those published on AustLII or the court's website, are assigned a medium neutral citation. The elements of this citation differ from a reported case citation. In the example below, Leahy v Barnes was the two hundred and twenty-sixth case to be heard in the Supreme Court of Queensland in 2013. Click on the blue symbols for a brief description of each citation element. Refer to the Australian Guide to Legal Citation rule 2.3.1 for further explanation.

A linked medium neutral case citation in the law databases will display the unreported version of the case. These versions are also often on AustLII or the relevant court’s website.

 

Older unreported cases

 

Medium neutral citation was introduced in the late 1990's. Prior unreported cases appear in the below format. Refer to the Australian Guide to Legal Citation rule 2.3.2 for further explanation.
