1. Be Brief
Be brief, short and succinct. Why? Reason 1: chances are you are screwing up. The shorter the time spent, the less you will screw up. Reason 2: A simple cross that restates the important part of the story in your terms is more easily absorbed and understood by the jury. You should never try to make more than 3 points on cross-examination. Two points are better than three and one point is better than two.
2. Use Plain Words
The jury can understand short questions and plain words. Drop the 50 dollar word in favor of the 2 dollar word. “Drive you car” instead of “operate your vehicle.”
3. Use Only Leading Questions
The law forbids questions on direct examination that suggest the answer. The lawyer is not competent to testify. On cross-examination the law permits questions that suggest the answer and allows the attorney to put his words in the witnesses’ mouth. Cross-examination, therefore, specifically permits you to take control of the witness, take him where you want to go, and tell your important point to the jury through the witness. Not asking controlled leading questions leaves too much wiggle room. What happened next? I would like to clear up a couple of points you made on direct? These questions are the antithesis of an effective cross-examination. Any questions which permit the witness to restate, explain or clarify the direct examination is a mistake. You should put the witness on autopilot so that all of the answers are series of yes, yes, yes!
4. Be Prepared
Never ask a question that you do not know the answer to. Cross is not a fishing expedition in which you uncover new facts or new surprises at the trial.
Listen to the answer. For some, cross-examination of an important witness causes stage fright; it confuses the mind and panic sets in. You have a hard time just getting the first question out, and you’re generally thinking about the next question and not listening to the answer.
6. Do Not Quarrel
Do not quarrel with the witness on cross-examination. When the answer to your question is absurd, false, irrational contradictory or the like; Stop, sit down. Resist the temptation to respond with “how can you say that, or how dare you make such an outrageous claim?” The answer to the question often elicits a response, which explains away the absurdity and rehabilitates the witness.
7. Avoid Repetitio
Never allow a witness to repeat on cross-examination what he said on direct examination. Why? The more times it is repeated, the more likely the jury is to believe it. Cross-examination should involve questions that have nothing to do with the direct examination. The examination should not follow the script of the direct examination.
8. Disallow Witness Explanation
Never permit the witness to explain anything on cross-examination. That is for your adversary to do.
9. Limit Questioning
Don’t ask the one question too many. Stop when you have made your point. Leave the argument for the jury.
10. Save for Summation
Save the ultimate point for summation. A prepared, clear and simple leading cross-examination that does not argue the case can best be brought together in final summation.on.
