What is the Precedent Map?
The Precedent Map is a visualisation of a case and its relationships to other cases. An alternative to lists of cases, the Precedent Map makes it easier to establish which ones may be of most relevance to your research and prioritise further reading. You also get a useful overview of how the case was received.
What do the circles represent?
- The large white circle represents the main case.
- The circles inside represent cases cited within the judgment.
- The circles outside represent those which have subsequently referred to your case. These are arranged in chronological order, going clockwise, with the earliest citation on the bottom-left, and the most recent on the bottom-right.
What do the sizes show?
- The size of a case’s circle represents the number of citation relationships it shares with the main case. The larger the circle the more relationships it has in common and the more likely it is to consider similar points of law.
- To see the shared citation relationships, click on a related authority.
On the precedent map for Oxley v Hiscock 2003 shown below, we have clicked Stack v Dowden. You can see that five cases which were cited in/subsequently cited Oxley v Hiscock, were also cited in/subsequently cited Stack v Dowden.
If we click on Grant v Edwards, a case cited in Oxley v Hiscock, you can see that only one case which subsequently cited Oxley v Hiscock, also cited Grant v Edwards.
Therefore Stack v Dowden is likely to have a more detailed discussion of more of the issues in Oxley v Hiscock.
