Follow this by the critical information that illustrates the headline. Then layer in more detailed information on background and research to support these major convincing points.

Ask yourself what order would best suit the presentation of the material. If you are giving a CLE program on a recent Supreme Court decision, you may start with the decision, then go back to the first legal decision to show the evolution of the law in this area. If you want to show how the recent decision deviated from precedent, you can chronologically show how judicial decisions have been rendered up until the most recent decision. To show the inadequacy of existing law, you can present specific cases and show the issues not addressed by appellate decisions. There are numerous other presentation sequences.
