The eleventh chapter of Henry G. Miller's On Trial, which I review briefly here a few years ago, is about the dirty tricks some lawyers try to pull at trial: slipping a trial brief to a judge without sharing it with the opposing lawyer; getting inadmissible evidence in front of the jury by means of speaking objections or asides to the opposing lawyer or the judge; coaching witnesses to shade the truth; and other such acts of discourtesy, rudeness, and questionable ethics.
What should you do about these sorts of dirty tricks? While Miller suggests "antidotes" for each of his examples, he ends with the following advice, which nicely sums up all of his suggestions:
Dealing with dirty tricks is never easy. There is no one right way. Judgment helps. Experience helps. Our choices vary case by case. Sometimes a sidebar conference, another time a motion in limine, and always an assignment to an effective judge is helpful . . . Talk to the judge. Most want to be fair. Make a record, object, protest, take exception, cross-examine. Motions to strike or for instructions to disregard or for mistrials are among our options. Be brave, be courteous, be professional, be calm, be alert, be bold.
This good advice will come in handy in a variety of situations at trial.
