Section 145 — When they may be asked

(1)Leading questions may be asked in cross‑examination, subject to the following qualifications:

(a)the question must not put into the mouth of the witness the very words which he or she is to echo back again; and

(b)the question must not assume that facts have been proved which have not been proved, or that particular answers have been given contrary to the fact.

(2)The court, in its discretion, may prohibit leading questions from being put to a witness who shows a strong interest or bias in favour of the cross‑examining party.
