With examination in chief the witness is allowed to tell their side
of the story. In cross-examination you do not want the witness to tell
the story. You indicate the point you wish to make and put it to the
witness. Leading questions therefore are used in cross-examination.
Leading questions provide for effective cross-examination because the
facts are supplied by the advocate instead of the witness and the
advocate has most of the control in order to get to the point they want
to make. During cross-examination you do not want a witness to tell
their story, you want them to verify the particular matters that you put
to them.
