Case citation
In some report series, for example in England and Australia, volumes are not numbered independently of the year. So the year and volume number (usually no greater than 4) are required to identify which book of the series has the case reported within its covers. In such citations, it is usual in these jurisdictions to apply square brackets "" to the year (which may not be the year that the case was decided, For example, a case decided in December 2001 may have been reported in 2002).
