Executive Summary: Key Legal and Evidentiary Issues

• Whether the Alberta Labour Relations Board, rather than the Court of King's Bench, holds exclusive jurisdiction over a dispute about internal union discipline allegedly applied in a discriminatory manner under s 152(1)(b) of the Labour Relations Code.

• Union members challenged disciplinary charges as being filed beyond the six-month limitation period prescribed by the union's own constitution, which the union refused to enforce.

• Characterization of the dispute's "essential character" must be determined by the underlying facts, not by how the parties have framed it legally, following the Weber/Regina Police framework.

• The Philip QB and Philip CA precedents establish that actions taken in breach of a union's own rules, procedures, bylaws, or constitution constitute discriminatory application of disciplinary standards under s 152(1)(b).

• Section 152(1)(b) distinguishes between "taking disciplinary action" and "imposing a penalty," meaning the provision applies to proceedings leading up to a disciplinary trial and not solely after penalties are imposed.

• A liberal interpretation of the Board's exclusive jurisdiction is favored to prevent fragmentation of proceedings and to align with the Code's remedial purpose of accessible, timely, and efficient dispute resolution.

Background and facts of the dispute
Michael Dunlop, Gary Loroff, Robert Provencher, and Mahmoud Rahime were members of the Carpenters' Regional Council of the United Brotherhood of Carpenters and Joiners of America, and also served as trustees of union-established pension and health and wellness trusts. The union received a complaint that the appellants made unauthorized changes to trust agreements and misappropriated funds. Disciplinary charges were later filed against the appellants.

The limitation period clause at issue
The union's constitution contained a specific limitation provision stating: "The Executive Committee shall dismiss any charge ... that is filed more than six (6) months after the date the violation occurred or reasonably should have been discovered." The appellants communicated to the union that the charges were brought "clearly and unequivocally well beyond the prescribed mandatory time limit" and asked that the charges be summarily dismissed, failing which they would seek compliance through the courts. The union responded that the alleged breaches underlying the charges "are of a continuing nature and subject to ongoing litigation," and therefore the six-month period for filing charges was "not applicable in these cases." The union refused to dismiss the charges and scheduled a disciplinary trial.

Proceedings before the Court of King's Bench
The appellants applied to the Court of King's Bench in regular chambers for urgent injunctive and declaratory relief to stop the disciplinary trial. They pleaded "serious issues with respect to the interpretation of the Constitution concerning the timeliness of the Charges." The chambers judge, Justice A.K. Akgungor, dismissed the application on July 15, 2024, holding that the dispute about the time limit was governed by the Code and fell within the exclusive jurisdiction of the Board. As the Court lacked jurisdiction over the underlying dispute, the injunction and declaratory relief were refused.

Complaint to the Alberta Labour Relations Board
Following the chambers judge's ruling, the appellants made a complaint to the Board alleging the union had engaged in an unfair labour practice by refusing to dismiss the charges for being out of time. The Board summarized the appellants' allegations as follows: "the Complaint alleges that the Executive Committee's interpretation of ... [the limitation period in] the Constitution is arbitrary, discriminatory, unlawful, unreasonable, and thus contrary to sections 152(1)(a) and 152(1)(b) of the Code." Specifically, the appellants argued the refusal to dismiss the charges was "arbitrary" because the limitation period in the constitution is mandatory and requires the Executive Committee to dismiss the charges if they are filed more than six months after the date the violation reasonably should have been discovered; "discriminatory" because the union is applying its membership rules to the complainants differently and less favourably than other members of the union who have charges against them dismissed as being untimely; and "unreasonable" because the purpose of the limitation period is to prevent the untimely pursuit of stale-dated allegations.

The appeal and the jurisdictional question
The appellants appealed the decision of the Court of King's Bench not to grant the injunctive and declaratory relief. The broad question on appeal was whether the chambers judge erred in finding the dispute was within the Board's exclusive jurisdiction. That raised two sub-issues: characterization of the appellants' dispute and the interpretation of s 152(1)(b) of the Code. The Court of Appeal applied the framework from Weber v Ontario Hydro and Regina Police Assn Inc v Regina (City) Board of Police Commissioners, which requires identification of the "essential character" of the dispute and interpretation of the relevant Code provisions over which the Board has exclusive jurisdiction. The essential character of a dispute is determined by the facts giving rise to it, not by how the parties have framed it legally, and a "liberal" approach to interpreting Code provisions is required. The appellants repeated their argument that their dispute was about the "correct interpretation of a union's constitution" and therefore outside the scope of the Board's statutory jurisdiction. The Court found this was a legal characterization, and that the essential character was properly determined by the factual matrix.

Interpretation of s 152(1)(b) and the Philip precedents
The central statutory provision, s 152(1)(b) of the Code, provides that no trade union shall "take disciplinary action against or impose any form of penalty on a person by applying to the person in a discriminatory manner the standards of discipline of the trade union." The Court of Appeal confirmed the interpretation from Philip v International Association of Bridge, Structural, Ornamental and Reinforcing Ironworkers (2008 ABQB 742, affirmed 2009 ABCA 400), which defined "discriminatory" in section 152(1) as meaning "to distinguish between individuals or groups on grounds that are illegal, arbitrary or unreasonable," and held that actions taken in breach of the union's own rules, procedures, bylaws, or constitution are discriminatory. The appellants suggested this Court did not expressly affirm the Philip QB principle and argued it should be distinguished because the facts of that case did not involve a complaint about unconstitutional discipline. The Court disagreed, finding that in Philip QB a unionized ironworker had alleged his union breached its contract with him, including the union constitution, by imposing various kinds of discipline, so it was necessary to determine whether disciplinary action in breach of the constitution could fall under s 152(1)(b). The statement about a breach of the constitution formed part of the legal principle essential to the decision. The Court further noted that differential treatment is always established when a union disciplines a member in breach of its constitution, since the union has a continuing contractual duty to comply with its constitution.

The appellants' remaining arguments
The appellants also contended that s 152(1)(b) has no application until disciplinary sanctions are imposed, submitting that the words "take disciplinary action against or impose any form of penalty" on a union member only apply to sanctions, so the court's jurisdiction to grant interim relief before sanctioning is not constrained. The Court of Appeal disagreed, noting that s 152(1)(b) expressly distinguishes between taking disciplinary action and imposing a penalty, with the former including the proceedings leading up to a disciplinary trial, regardless of whether a penalty is later imposed. The appellants' interpretation would render redundant the words "take disciplinary action" and was contrary to well-recognized principles of statutory construction. Additionally, the appellants provided cases from other provinces and the federal sector to suggest labour boards are not typically given jurisdiction to interpret a union's constitution. The Court found those cases unpersuasive and readily distinguishable, noting that many did not involve the interpretation of the equivalent of s 152(1)(b), and none held that a provision equivalent to s 152(1)(b) excludes disciplinary action which breaches the union's constitution in a discriminatory way.

Ruling and outcome
The Court of Appeal of Alberta, in a memorandum of judgment filed at Edmonton on March 23, 2026, by Justices Crighton and Feth (Chief Justice Khullar did not participate in the final disposition of the judgment), dismissed the appeal. The Court held that the essential character of the appellants' dispute with the union is governed by s 152(1)(b) of the Code, that the Board has exclusive jurisdiction to hear the dispute, and that the chambers judge did not err in declining jurisdiction to consider the appellants' application for urgent injunctive and declaratory relief. The respondents — the Carpenters' Regional Council of the United Brotherhood of Carpenters and Joiners of America, the United Brotherhood of Carpenters and Joiners of America, Local Union 2103, Local Union 2010, and Kurt Kashuba — were the successful parties. No specific monetary amount was ordered or awarded, as the judgment concerned jurisdictional issues and did not reference any costs or damages.
