If the trial judge gives, or proposes to give, a direction under section 21, defence counsel may request under section 12 that the trial judge also direct the jury that—
(a) there are all sorts of reasons why a person might behave in a way that makes the person look guilty; and
(b) the accused may have engaged in the conduct even though the accused is not guilty of the offence charged; and
(c) even if the jury thinks that the conduct makes the accused look guilty, that does not necessarily mean that the accused is guilty.
Section 14 requires the trial judge to give this direction, if requested, unless there are good reasons for not doing so. Section 16 requires the trial judge to give a direction if the trial judge considers that there are substantial and compelling reasons for doing so.
