Summary
In November 2021, the Honourable Madam Justice E. Sidnell
released a procedural decision regarding amending a party's
undertaking responses in the case of Signalta Resources Limited
v. Canadian Natural Resources Limited, 2021 ABQB 867. The
decision relates to an attempt by the defendant, Canadian Natural
Resources Limited (CNRL), to clarify or replace five of its
undertaking responses (UTRs) several days before trial. The five
UTRs in question were given by its former corporate representative
several years earlier. The plaintiff had prepared to read-in the
defendant's UTRs at trial pursuant to the Alberta Rules of
Court, Alta Reg 124/2010 (the Rules).
The trial judge refused to allow CNRL's amended UTRs to be
read-in at trial and held that CNRL's failure to provide an
affidavit, setting out the corrections to CNRL's evidence in
accordance with Rule 5.27 of the Rules, created prejudice that
could only be overcome by rejecting the amended UTRs.
