 When a case has a written decision, it can be published in lots of different places. For example, when the High Court publishes a decision, it's usually available shortly on their website. A case can also be collected and published in law reports. For the case of Marbeau and Queensland number two, it has been published by the High Court of Australia, in the Commonwealth Law Reports, the Australian Law Reports and other places. Because of this, when you see a case citation in your textbook, lecture notes or in a law database, you will have a list of citations that will tell you all the different places that you can find the case. These citations are called parallel citations as they sit next to each other. When you cite a case in your assignment, you will only need to choose one citation per case. The AGLC lets us know that where possible, we should cite the most authorised version. Check the AGLC that has a list of preference order for law reports. If you need help picking your citation, ask us at the library.
