A leading question is one that carries its own answer. On direct examination it is mostly forbidden. On cross it is the whole instrument. Knowing the difference is knowing who is really testifying.
A leading question suggests the answer inside the question. “You never checked your mirror, did you.” The witness is left with almost nothing to do but agree or disagree. That single feature, that the question supplies the answer, is what makes leading questions barred in one place and indispensable in another.
The rule draws the line by who called the witness. On direct examination, when a lawyer questions a friendly witness, leading is not allowed except as needed to develop the testimony, because the point of direct is to let the witness tell the story in the witness’s own words. On cross-examination, and when a party is forced to call a hostile witness or an adverse party, leading is allowed, because there the lawyer is not drawing out a story but testing one.
That is why the great cross-examiners speak almost entirely in leading questions. Irving Younger taught it as control. On cross you do not ask the witness what happened. You tell the witness what happened, one small fact at a time, and the witness agrees with each piece or is impeached by the record. The answers come back yes, yes, yes, and the lawyer, not the witness, is building the point. Ask an open question on cross and you hand the floor back to the other side’s witness. Ask a leading one and you keep it.
On direct it is the reverse, and the reversal is the point. A jury believes the story a witness tells in his own words far more than the story a lawyer feeds him and he only confirms. A lawyer who leads his own witness through the important part has told the jury, without meaning to, whose words those really are. The rule against leading on direct is not just procedure. It protects the very thing that makes the testimony worth hearing.
So the word to carry is leading, and the discipline is to know which examination you are in. Save the leading questions for the witness you are testing. Give them away for the witness you are trusting to tell the truth in his own voice.
The rule on leading questions is Texas Rule of Evidence 611(c): leading questions are generally improper on direct examination except as necessary to develop the witness’s testimony, and are permitted on cross-examination and when a party calls a hostile witness, an adverse party, or a witness identified with an adverse party. This is general information, not legal advice.
