At the trial, the wife had refused to waive the mediation privilege, seeking to prevent the
husband from introducing any evidence in his defense of what transpired during the
mediation. The trial court would not allow wife’s claim of the mediation privilege to
prevent husband from offering this evidence. Instead, the trial court allowed the
husband, over the wife’s objection, to introduce evidence of what transpired during the
mediation, including evidence from the mediator. The trial court ruled that the
husband’s evidence defeated the wife’s claim, that he had met his burden of proof, and
ruled that the agreement was enforceable.
The Court of Appeal held that the trial court erred in permitting husband’s evidence to
come in over wife’s objections and that the mediation privilege trumped the undue
influence presumption. As the wife did not waive the mediation privilege, it reasoned,
then none of hudband’s evidence of what transpired during the mediation should have
been admitted at the hearing. (In holding that the presumption of undue influence was
outweighed by the mediation privilege, however, the Court of Appeal concluded that the
trial court should not have placed the burden of proof on husband, that instead wife
carried the burden of proof and that, indeed, wife did not meet her burden.)
The opinion presents three reasons why the undue influence presumption must bend to
the mediation privilege. First, the Court reasoned, the presumption does not apply to
mediated agreements because mediators, by definition, work to balance any
imbalances in negotiating skills between the parties, and to minimize any actual undue
