interfering with jurors' impartiality is a form of discrimination. It
involves making distinctions on the basis of class or category
without regard to individual merit. It rests on preconceptions and
unchallenged assumptions that unconsciously shape the daily
behaviour of individuals. Buried deep in the human psyche, these
preconceptions cannot be easily and effectively identified and set
aside, even if one wishes to do so. For this reason, it cannot be
assumed that judicial directions to act impartially will always
effectively counter racial prejudice: see Johnson, supra. Doherty
J.A. recognized this in Parks, supra, at p. 371:
In deciding whether the post-jury selection safeguards
against partiality provide a reliable antidote to racial
bias, the nature of that bias must be emphasized. For
some people, anti-black biases rest on unstated and
unchallenged assumptions learned over a lifetime.
Those assumptions shape the daily behaviour of
individuals, often without any conscious reference to
them. In my opinion, attitudes which are engrained in
an individual's subconscious, and reflected in both
individual and institutional conduct within the
community, will prove more resistant to judicial
cleansing than will opinions based on yesterday's news
and referable to a specific person or event.
Racial prejudice and its effects are as invasive and elusive as they
are corrosive. We should not assume that instructions from the
judge or other safeguards will eliminate biases that may be deeply
ingrained in the subconscious psyches of jurors. Rather, we should
acknowledge the destructive potential of subconscious racial
prejudice by recognizing that the post-jury selection safeguards may
not suffice. Where doubts are raised, the better policy is to err on the
side of caution and permit prejudices to be examined. Only then can
we know with any certainty whether they exist and whether they can
be set aside or not. … (quoted at para. 30 of Troy)
[480] The Court in Troy also restated the basic general principles which apply to the
question of proof in a case of this kind:
Mr. Troy complained that he was discriminated against based on racial
stereotyping. He does not need to show that discrimination comprised the
sole factor in the conduct complained of, and he only needs to raise a
prima facie case that it was a factor. The burden is not an onerous one.
This is because the case law recognizes that discrimination is rarely
openly displayed, and in most cases, must be inferred from circumstantial
evidence. (at para. 25)
