What is the test to relieve against an implied undertaking?

In this court, Williams J. most recently described the test to be met on the type of application before me as this: Where a court order is sought to relieve against the implied undertaking, the applicant will have the onus of satisfying the court on a balance of probabilities that the interest to be advanced through the sought-after disclosure is greater than the values that underpin the rationale for the implied undertaking. Central to the analysis will be a careful consideration of any prejudice that will be caused to the party who initially provided the material at issue. Of course, it goes without saying that the material must be relevant to the issues in the action in which the disclosure is sought. British Columbia v. Tekavec, 2012 BCSC 1348 (CanLII), at para. 13.
