Courtroom Conduct Matters. Yes, Counsel: That Includes You, by Kacy Miller, Persuasion Matters
Regardless of who sits at the counsel table or part of the team sitting in the gallery, courtroom conduct matters. Many judges have their own set of courtroom rules. Like all local rules, follow them exactly. These are rules, not suggestions. It is especially important that your client understands the importance of proper court etiquette, as well as any family members or friends who may be seated in the gallery.
I have seen bad behavior by clients and counsel alike. Some clients have trouble controlling themselves. Some attorneys act more like they are in a theater rather than a courtroom. Go to court often enough, and you will quickly see what impresses a judge or jury and what doesn’t. -CCE
