405
. With respect to preliminary fact determinations not governed
by Section 403 or 404:
(a) When the existence of a preliminary fact is disputed, the
court shall indicate which party has the burden of producing evidence
and the burden of proof on the issue as implied by the rule of law
under which the question arises. The court shall determine the
existence or nonexistence of the preliminary fact and shall admit or
exclude the proffered evidence as required by the rule of law under
which the question arises.
(b) If a preliminary fact is also a fact in issue in the action:
(1) The jury shall not be informed of the court's determination as
to the existence or nonexistence of the preliminary fact.
(2) If the proffered evidence is admitted, the jury shall not be
instructed to disregard the evidence if its determination of the fact
differs from the court's determination of the preliminary fact.
