The following excerpt is from Wright v. Thomas, 2012 BCSC 2021 (CanLII):
Whether the implied undertaking rule even applies in this case might be in doubt. In Cochrane v. Heir, 2011 BCSC 477, the court ruled that a plaintiff must provide records obtained in a previous personal injury action as part of disclosure obligations under Rule 7‑1. Furthermore, one might query whether evidence disclosed at a public trial and now part of a public record is subject to the implied undertaking rule. The underlying purpose of the implied undertaking rule is to protect the privacy of an individual who is compelled to disclose certain information in the pre‑trial process.
