Executive Summary: Key Legal and Evidentiary Issues

• The appeal turned on whether Dale McMullen qualified as a "near client" of Gowling WLG (Canada) LLP for conflict-of-interest purposes.
   
• Confidential information was not at risk, according to both the case management justice and the Court of Appeal.
   
• Four related legal errors were identified in the lower court's reasoning on the near-client finding.
   
• A finding that Gowling drafted an indemnity agreement between McMullen and Piikani Investment Corporation was not supported by the evidence.
   
• Corporate separateness meant McMullen's role as key contact for Piikani Investment Corporation and Piikani Energy Corporation did not, by itself, create client-like duties.
   
• Ms. Hanert's non-disqualification was upheld, and the disqualification of Gowling was overturned.
   

Facts of the case

Piikani Nation and related parties sued Dale McMullen and others in 2010 (Action 1001-10326), alleging misconduct connected to the Piikani Trust. McMullen had been a senior management employee and director of Piikani Investment Corporation (PIC) and Piikani Energy Corporation (PEC), two Piikani Nation business entities that were not themselves parties to the action. In 2011, McMullen filed a separate application against Piikani Nation seeking indemnification for his legal fees in defending Action 1001-10326 (Action 1101-11127). Gowling had previously performed legal work for PIC and PEC while McMullen was its main point of contact, and had also represented McMullen personally in a 2008 employment matter that was closed before the two lawyers involved left the firm. Caireen Hanert, long-standing counsel for Piikani Nation, moved to Gowling in 2018 and brought the Piikani Nation files with her. In 2019, McMullen applied to disqualify Gowling and Hanert, arguing Gowling was in a disqualifying conflict of interest. The case management justice found no confidential information was at risk but disqualified Gowling on the basis that McMullen was a "near client," reasoning that McMullen's role as the key contact between Gowling and PIC created duties that a subsequent retainer against him would compromise. The justice also found McMullen had a likely right to access Gowling's files from that period. Subsequent to the disqualification ruling, McMullen was found in contempt of court for failing to attend questioning and misusing privileged materials, and Piikani Nation was permitted to discontinue Action 1001-10326 against him on a without-costs basis after the appellants' factum was filed.

Policy terms or contractual clauses at issue

The dispute centered on two potential indemnity agreements: one between Piikani Nation and McMullen, dated April 2004, and one alleged to exist between PIC and McMullen. The case management justice had found that Gowling could not properly act against McMullen because McMullen was defending part of the Piikani Nation action on the basis that he was entitled to indemnification under an agreement "drafted by Gowling and on which they presumably advised both Mr. McMullen and PIC." The evidence showed the 2004 Piikani Nation–McMullen agreement predated Gowling's involvement and was instead drafted by McMullen's then-counsel, Blake Cassels & Graydon LLP, a point McMullen himself had conceded in his Reply Brief and in oral argument below. Whether a separate indemnity agreement existed directly between McMullen and PIC remained unclear on the record, and McMullen's own affidavit evidence did not specify Gowling's actual involvement with his indemnification.

Reasoning and analysis

The Court of Appeal reviewed the governing framework for conflicts of interest, including the duty to avoid misuse of confidential information and the duty of loyalty owed to current and former clients, as established in cases such as R v Neil and Canadian National Railway Co v McKercher LLP. It distinguished these duties from the more exceptional "near client" doctrine, under which a non-client may seek disqualification of a lawyer only where a reasonable expectation of confidentiality or loyalty is established. Applying this framework, the Court found the case management justice made four related errors: treating McMullen's role as client contact alone as sufficient to make him a "near client"; effectively treating PIC and PEC as closely held by McMullen rather than by Piikani Nation; misapplying the "composite rule" from Gainers Inc v Pocklington as a test for client status rather than for disqualifying a lawyer from acting against a non-client; and conflating the near-client concept with former-client status by applying the related-matter test from Brookville Carriers Flatbed GP Inc v Blackjack Transport Ltd. The Court emphasized that corporations are separate legal entities from their officers and directors, and that solicitor-client privilege and confidentiality belonged to PIC and PEC, not to McMullen personally. It also found the justice's conclusion that Gowling drafted the relevant indemnity agreement was a palpable and overriding error unsupported by the evidence. On the separate question of whether McMullen was a former client in a related matter, the Court upheld the justice's finding that the 2008 employment matter and other prior actions involving Gowling were unrelated to the Piikani Nation litigation, and that Hanert herself was not disqualified given her uncontroverted lack of access to the walled files. Finally, the Court held the justice erred in stating McMullen likely had a right to access Gowling's files, since privilege belonged to PIC or PEC and McMullen could not retroactively waive it on their behalf.

Ruling and overall outcome

The Court of Appeal allowed the appeal, concluding that the case management justice's disqualification of Gowling rested on legal errors regarding the "near client" doctrine and an unsupported factual finding about the indemnity agreement. The appellants — Piikani Nation and the related parties, including Gowling WLG (Canada) LLP and Caireen Hanert — were the successful party, with the Court holding that Gowling should not have been disqualified from continuing to act for Piikani Nation. The decision did not order or grant any monetary award, damages, or costs; the ruling addressed only counsel disqualification, so the monetary award here is $0.
