Overview of the sources of legal authority (primary and secondary sources) and basic types of legal writing (such as a legal memorandum and case brief). Legal professionals need to communicate legal information effectively in different formats. In the same role as a legal assistant at the legal aid center, you have been asked to create a short PowerPoint, in which you provide a concise overview of legal research and writing components. Your PowerPoint should identify the types of sources of legal authority, giving brief definitions and examples for the types of law. As you create your PowerPoint, focus on how to present the information effectively in this format - such as using bullet-points and visually engaging information.
