Institutio Oratoria

In the case of advocates for the defence examination is in some respects easier, in some more difficult. It is more difficult because it is rarely possible for them to have any previous knowledge of what the witness is likely to say, and easier because, when they come to cross-examine, they know what he has already said.

Consequently in view of the uncertainty involved, there is need for careful inquiry with a view to discovering the character of the witness against the accused and what are his motives for hostility and what its extent: and all such points about the witness should be set forth in advance and disposed of, whether we desire to represent the evidence against the accused as instigated by hatred, envy, bribery or influence. Further, if our opponents bring forward only a small number of witnesses, we must attack them on that head; if on the other hand they produce an excessive number, we must accuse them of conspiracy: if the witnesses are persons of inconspicuous rank, we must minimise their importance, while if they are powerful, we shall accuse our adversaries of bringing undue influence to bear.

It will, however, be still more helpful if we expose the motives which they have for desiring to injure the accused, and these will vary according to the nature of the case and the parties concerned. For the other lines of argument mentioned above are often answered by the employment of commonplaces on similar lines, since the prosecutor, if he produce but few witnesses of inconspicuous rank, can parade the simple honesty of his methods on the ground that he has produced none save those who

But at times, just as we have to praise individual witnesses, so we may have to demolish them, whether their evidence has been given in documentary form or they have been summoned to appear in person. This was easier and of more frequent occurrence in the days when the examination of the witnesses was not deferred till after the conclusion of the pleading. [*]( It is not clear to what Quintilian refers. There are, it is true, passages in Cicero where the orator speaks of evidence as already given, but the speeches where these references are found are all second pleadings. ) With regard to what we should say against individual witnesses, no general rules can be laid down: it will depend on the personality of the witness.

It remains to consider the technique to be followed in the examination of witnesses. The first essential is to know your witness. For a timid witness may be terrorised, a fool outwitted, an irascible man provoked, and vanity flattered. The shrewd and self-possessed witness, on the other hand, must be dismissed at once as being malicious and obstinate; or refuted, not by cross-examination, but by a brief speech from the counsel for the defence; or may be put out of countenance by some jest, if a favourable opportunity presents itself; or, if his past life admits of criticism, his credit may be overthrown by the scandalous charges which can be brought against him.
