by Ryan H. Flax (Former) Managing Director, Litigation Consulting A2L Consulting We strongly advocate that counsel must use a visual presentation to support his or her oral argument at trial (and anywhere they need to be persuasive). This most commonly happens during opening statements and closing arguments at trial and the dominant format for such presentations is PowerPoint – a very good tool. However, like cutting your own hair or doing your own dental work, we must again caution you that you must really know what you’re doing because your case may depend on it. On January 22, 2015, the Supreme Court of the State of Washington published its opinion in State v. Walker, overturning the State Prosecutor’s conviction of an accused murderer because the attorney went too far with his demonstrative evidence in closing. A murderer has potentially been freed because, in the Court’s view, counsel was inflammatory in his presentation and “appealed to passion and prejudice” of the jury. Certainly as zealous advocates we do want to appeal to the passion of jurors on some level. We need their emotions to be in sync with the law and evidence, but what might be too much so as to prejudice the proceedings? Let’s explore the Washington Supreme Court’s opinion to see.
