General Principle

Voir également: Examinations et Cross-Examinations

An examination-in-chief or direct examination is where the party calling a witness to give evidence asks the witness questions to elicit evidence.

Rule Against Leading Questions

A leading question is a question that suggests the desired answer.^[1] In general, counsel cannot ask leading questions on of the witness that they call.^[2] Leading questions are questions that clearly seek a particular answer (eg. "you saw the accused, didn't you?") or are questions that assume a foundation not in evidence (eg. "what happened after the accused stabbed him?").^[3]

Rationale

The reason for not allowing leading questions include:^[4]

bias of the witness in favour of the calling party
the danger that the calling party will only bring out helpful information without any balance that could come from the witnesses own version^[5]
the possibility that the witness will merely agree with everything put to the witness by the calling party.^[6]
a witness who is nervous, not alert, confused or otherwise easily persuaded may accept the suggestion of a leading question without reflection.^[7]

The leading question may "impose the questioner’s will on the witness so as to elicit inaccurate information, absent an intention to do so on the part of the counsel or witness”^[8]

The importance of not leading depends on the circumstances. The rule should be flexible at the least for the sake of expediency.^[9]

Discretion in the "Interests of Justice"

A judge has discretion to allow any leading question where it is "necessary in the interests of justice."^[10]

Exception

It is usually permissible to lead on a number of issues:

introductory or non-controversial matters such as name, address, position, etc.^[11]
for the purpose of identifying persons or things^[12]
where "necessary to direct the witness to a particular matter or field of inquiry."^[13]
to allow one witness to contradict another regarding statements made by that other^[14]
where the witness is declared hostile;
where the witness is defective based on age, education, language, mental capacity^[15]
where it is a complicated matter, at the judge's discretion^[16]

A judge has discretion to allow leading where it is in the interest of justice.^[17]

Consequence of Leading Questions

The answer to a leading question is not necessaries inadmissible but will carry very little or less weight, especially on critical issues.^[18]

The weight given to an answer from a leading question will depend on "how leading the question was, the subject matter and other evidence before the Court." ^[19] It will often be that the inappropriateness of the question, and so the weight given to the answer, will be assessed in the light of whole circumstances of the case, after subsequent testimony of the witness.^[20]

Objections

Objections should not be made to leading questions unless the question is "critical" to the case.^[21]

The use of leading questions will be tolerated more when for the purpose of a "controlled examination" rather than where is becomes a "cross‑examination for the purpose of discrediting or contradicting" the witness.^[22]
