To begin, you are going to briefly discuss the current legal status for the issue in question, and explain what is controversial, or more specifically what the (likely) two competing viewpoints are arguing. This needs to be from an experimental research perspective, rather than a more societally-focused (i.e. sociological or criminological) perspective.

You will then take a stand, and to back this up, will discuss the latest empirical/experimental research to assist the court in deciding whether your view is valid. For example, if you chose to discuss whether the sequential lineup was better than the simultaneous one, you would briefly state the two views (though note for topics such as this one, you need to do more than reiterate what is in the text or lecture modules – focus on the latest research), then pick a side, explaining what research supports this side. So – you do need to address the ‘other side’ in order to refute the arguments that might come from that direction. As you are writing a court ‘brief’ you will have to write clearly and succinctly so as to get across your key points in quite a limited space.
