Justiciability. Highwood Congregation of Jehovah’s Witnesses (Judicial Committee) v. Wall
In Highwood Congregation of Jehovah’s Witnesses (Judicial Committee) v. Wall (SCC, 2018) the Supreme Court of Canada reviewed the concept of justiciability:
 This appeal may be allowed for the reasons given above. However, I also offer some supplementary comments on justiciability, given that it was an issue raised by the parties and dealt with at the Court of Appeal. In addition to questions of jurisdiction, justiciability limits the extent to which courts may engage with decisions by voluntary associations even when the intervention is sought only on the basis of procedural fairness. Justiciability relates to the subject matter of a dispute. The general question is this: Is the issue one that is appropriate for a court to decide?
 Lorne M. Sossin defines justiciability as
a set of judge-made rules, norms and principles delineating the scope of judicial intervention in social, political and economic life. In short, if a subject-matter is held to be suitable for judicial determination, it is said to be justiciable; if a subject-matter is held not to be suitable for judicial determination, it is said to be non-justiciable.(Boundaries of Judicial Review: The Law of Justiciability in Canada (2nd ed. 2012), at p. 7)
Put more simply, “[j]usticiability is about deciding whether to decide a matter in the courts”: ibid., at p. 1.
 There is no single set of rules delineating the scope of justiciability. Indeed, justiciability depends to some degree on context, and the proper approach to determining justiciability must be flexible. The court should ask whether it has the institutional capacity and legitimacy to adjudicate the matter: see Sossin, at p. 294. In determining this, courts should consider “that the matter before the court would be an economical and efficient investment of judicial resources to resolve, that there is a sufficient factual and evidentiary basis for the claim, that there would be an adequate adversarial presentation of the parties’ positions and that no other administrative or political body has been given prior jurisdiction of the matter by statute” (ibid.).
 By way of example, the courts may not have the legitimacy to assist in resolving a dispute about the greatest hockey player of all time, about a bridge player who is left out of his regular weekly game night, or about a cousin who thinks she should have been invited to a wedding: Court of Appeal reasons, at paras. 82-84, per Wakeling J.A.
 This Court has considered the relevance of religion to the question of justiciability. In Bruker v. Marcovitz, 2007 SCC 54,  3 S.C.R. 607, at para. 41, Justice Abella stated: “The fact that a dispute has a religious aspect does not by itself make it non-justiciable.” That being said, courts should not decide matters of religious dogma. As this Court noted in Syndicat Northcrest v. Amselem, 2004 SCC 47,  2 S.C.R. 551, at para. 50: “Secular judicial determinations of theological or religious disputes, or of contentious matters of religious doctrine, unjustifiably entangle the court in the affairs of religion.” The courts have neither legitimacy nor institutional capacity to deal with such issues, and have repeatedly declined to consider them: see Demiris v. Hellenic Community of Vancouver, 2000 BCSC 733, at para. 33 (CanLII); Amselem, at paras. 49-51.
 In Lakeside Colony, this Court held (at p. 175 (emphasis added)):
In deciding the membership or residence status of the defendants, the court must determine whether they have been validly expelled from the colony. It is not incumbent on the court to review the merits of the decision to expel. It is, however, called upon to determine whether the purported expulsion was carried out according to the applicable rules, with regard to the principles of natural justice, and without mala fides. This standard goes back at least to this statement by Stirling J. in Baird v. Wells (1890), 44 Ch. D. 661, at p. 670:The foregoing passage makes clear that the courts will not consider the merits of a religious tenet; such matters are not justiciable.
The only questions which this Court can entertain are: first, whether the rules of the club have been observed; secondly, whether anything has been done contrary to natural justice; and, thirdly, whether the decision complained of has been come to bona fide.
 In addition, sometimes even the procedural rules of a particular religious group may involve the interpretation of religious doctrine. For instance, the Organized to Do Jehovah’s Will handbook (2005) outlines the procedure to be followed in cases of serious wrongdoing: “After taking the steps outlined at Matthew 18:15, 16, some individual brothers or sisters may report to the elders cases of unresolved serious wrongdoing” (p. 151). The courts lack the legitimacy and institutional capacity to determine whether the steps outlined in Matthew have been followed. These types of procedural issues are also not justiciable. That being said, courts may still review procedural rules where they are based on a contract between two parties, even where the contract is meant to give effect to doctrinal religious principles: Marcovitz, at para. 47. But here, Mr. Wall has not shown that his legal rights were at stake.
 Justiciability was raised in another way. Both the Congregation and Mr. Wall argued that their freedom of religion and freedom of association should inform this Court’s decision. The dissenting justice in the Court of Appeal made comments on this basis and suggested that religious matters were not justiciable due in part to the protection of freedom of religion in s. 2(a) of the Canadian Charter of Rights and Freedoms. As this Court held in RWDSU v. Dolphin Delivery Ltd., 1986 CanLII 5 (SCC),  2 S.C.R. 573, at p. 603, the Charter does not apply to private litigation. Section 32 specifies that the Charter applies to the legislative, executive and administrative branches of government: ibid., at pp. 603-4. The Charter does not directly apply to this dispute as no state action is being challenged, although the Charter may inform the development of the common law: ibid., at p. 603. In the end, religious groups are free to determine their own membership and rules; courts will not intervene in such matters save where it is necessary to resolve an underlying legal dispute.
