See AGLC rule 2.8
Always check (using CaseBase or FirstPoint) to see if the case has been reported. If a reported version is available, use the reported version in preference to the unreported decision. If it is reported in an authorised series, use the authorised reports (for example: Commonwealth Law Reports, Federal Court Reports, Victorian Reports).
If the decision is not reported, use the medium neutral citation, if it is available. Medium neutral citations were introduced by the courts in the 1990s so that any judgment could be referred to, using a uniform style, no matter what medium it appears in. Most earlier cases do not have medium neutral citations. An exception is the High Court of Australia - all of its reported decisions going back to 1903 have now been given medium neutral citations.
If the unreported decision was found on an electronic database, do not cite the database. (The same unreported decisions can often be found on different databases.) The medium neutral citation is sufficient.
The details which must be included are:
Case name - Put in italics.
Year - Put in square brackets.
Unique court identifier - Use 'VSC' for decisions from the Victorian Supreme Court, 'VSCA' for decisions from the Victorian Supreme Court, Court of Appeal, 'HCA' for the High Court of Australia, etc. (the judgment itself should identify the relevant unique court identifier).
Judgment number - This will be the judgment number allocated by the court for the relevant year.
The judgment date -in parentheses (round brackets).
Pinpoint - Refer to the paragraph number of the judgment, not the page number. Use square brackets.
