Abstract

This article discusses whether private law disputes are ever non-justiciable. I argue that, as a general rule, a private law dispute is justiciable if, and only if, the claim asserts that the plaintiff’s legal rights have been breached by the defendant. Contrary to recent suggestions, there is no rule that renders disputes non-justiciable because they involve religion. Rather, the only private law disputes that may be non-justiciable despite asserting the breach of a private right are those which would require a court to exceed its role under the separation of powers.

3. The idea of a cause of action is broader than the idea of a legal right being breached, because a plaintiff may have a cause of action when they anticipate that their legal right is going to be breached and take pre-emptive legal action to prevent the breach. Such situations may be dealt with by seeking declaratory relief. See generally Malcolm Rowe & Diane Shnier, “The Limits of the Declaratory Judgment” (2022) 67 McGill LJ 295 at 310, DOI: . I will bracket this complication for purposes of this article and will proceed as though all causes of action involve the breach of legal rights.

16. Kennedy & Kinsinger refer to this as the idea that “religious disputes are only deemed to be injusticiable so long as they fail to meet the procedural requirements for courts to adjudicate such matters.” Supra note 4 at 307. The requirements they have in mind, however, are not procedural but substantive (requirements such as consideration, certainty of terms, and contractual intention).

35. See Tully v Farrell, [1876] OJ No 98 (ON Ct Ch). As MH Ogilvie argues, “there can be little doubt, from the perspective of [the] civil authorities, that they enjoy as much civil jurisdiction over religious institutions as over any other individual or group of individuals.” See Religious Institutions and the Law in Canada, 4th ed (Irwin Law, 2017) at 228.

36. See McCaw v United Church of Canada, 1991 CanLII 7048 (ONCA). See also Davis v United Church of Canada, 1992 CanLII 7731 (ONSC). Actions by Roman Catholic priests have been stayed where they failed to exhaust their internal remedies under canon law. In such cases, the relation between priest and church is contractual, and the rules of canon law are terms of that contract. See Pederson v Fulton, 1994 CanLII 7483 (ONSC) [Pederson]; Hart v Roman Catholic Episcopal Corporation of the Diocese of Kingston, in Canada, 2011 ONCA 728 [Hart]. In Anozie v McGrattan, 2017 HRTO 1208, and Elamplakatt v Roman Catholic Diocese of London, 2022 HRTO 411, disputes subject to canon law were held to be outside the jurisdiction of the Human Rights Tribunal of Ontario.

See also Itter v Howe, [1896] OJ No 31 (ONCA). I do not mean to suggest that these rules are beyond criticism. In particular, the courts’ focus on doctrine in church property disputes can have the effect of freezing a church in the past, preventing its views from evolving over time. This seems inconsistent with the autonomy of voluntary associations, as noted by Lord Cranworth. See Forbes, supra note 20 (“[a] religious body…forms an imperium in imperio, of which the Synod is the supreme body….If this is so, I feel it impossible to say that any canons which they establish can be treated as being ultra vires” at 9). Similarly, John Neville Figgis criticized Free Church on the basis that it failed to treat the church as a living organization, capable of developing over time. See David Runciman, Pluralism and the Personality of the State (Cambridge University Press, 1997) at 135, DOI: ; John Neville Figgis, Churches in the Modern State (Longmans, Green and Co, 1913) at 18-22.

44. Bentley, supra note 43 at para 76 [emphasis in original]. This approach aligns with certain earlier cases where courts awarded property to the majority of a congregation in a dispute, regardless of whether the proposed changes amounted to a fundamental change of doctrine, on the basis either that the majority was empowered by the congregational constitution to make changes or that the changes had been made in accordance with the denomination’s hierarchical processes for so doing.

50. [1976] AC 397 at 400 (HL (Eng)) [Blathwayt]. In another matter, a provision requiring a son to “rejoin” the Catholic Church was held not to be void for uncertainty. See Re Starr, 1946 CanLII 70 (ONCA). Another provision required the testator’s nephews to be members of a Protestant church “in good faith and standing.” See Re Going, 1951 CanLII 87 (ONCA). The court held that it was unnecessary to decide whether the condition was valid, because this would make no difference. Grattan & Conway discuss several further cases and conclude that, aside from Royal Trust Company, references to other religions were found to be sufficiently certain. Grattan & Conway, supra note 47 at 525-26.

53. See Levitts, supra note 5.

54. Sossin & Kennedy list Levitts as a case in which a court “declined to intervene, even when private interests are clearly affected.” Supra note 4 at 540. The same proposition, supported by the same cases, occurs in Kennedy & Kinsinger, supra note 4 at 300. But the issue is private rights, not private interests; there can be harms to interests which are not wrongs. See JD v East Berkshire Community Health NHS Trust, [2005] UKHL 23 at para 100. This point also applies to several other cases relied on by both Sossin & Kennedy and Kennedy & Kinsinger. See e.g. Demiris v Hellenic Community, 2000 BCSC 733 at para 33 (where the court refused to comment on whether a church should withdraw the charter of a parish); Mathai v George, 2019 ABQB 116 at para 13 (which concerned the removal of the right to hold office and vote in church elections); McTaggart v Jehovah’s Witnesses, 2019 HRTO 207 (where the discrimination did not occur in an area covered by the Human Rights Code); Sivanadian v Kanagaratnam, 2020 ONSC 6760 (which was an application for judicial review, not a private law action, and in any event did not involve a religious organization). None of these cases stand for the proposition for which they are cited.

69. Kennedy & Kinsinger, supra note 4 at 316 suggest something similar. In Canada, the Charter does have a role in informing the development of the common law. See RWDSU v Dolphin Delivery Ltd, 1986 CanLII 5 at para 39 (SCC).

73. Ibid at 196.

75. I use “certain norms” because administrative law contains norms that relate public authorities to the individuals affected by their decisions. See Megan Pfiffer, “Administrative Law as a Source of Rights” (2025) 88 Mod L Rev 366, DOI: . It would require further investigation to determine whether public law necessarily contains norms that relate public authorities to the public broadly, or whether it could be revised so that all its norms related public authorities to affected individuals. I do not mean to take a position on this here.

76. See Rules of Civil Procedure, RRO 1990, Reg 194, rr 1.03(1), 7.02(1).

77. See Dawson v Dawson, 2020 ONSC 6724 at para 30.

78. See e.g. David Mullan, Book Review of Boundaries of Judicial Review: The Law of Justiciability in Canada by Lorne Sossin, (2000) 38 Osgoode Hall LJ 221 at 227, DOI: .

79. If standing is a Hohfeldian power, then justiciability might be its counterpart, a Hohfeldian liability: If the plaintiff exercises their power to sue, then the court will have a duty to decide it. However, given that it is controversial whether Hohfeld’s scheme can be applied to public bodies, I am stating the rule without relying on that scheme. On this issue, see TM Sichelman, “Some Fundamental Legal Conceptions as Applied in Judicial Reasoning” in Shyamkrishna Balganesh, Ted M Sichelman & Henry E Smith, eds, Wesley Hohfeld A Century Later: Edited Work, Select Personal Papers, and Original Commentaries (Cambridge University Press, 2022) 15 at 23, DOI: ; Nicholas Bamforth, “Hohfeldian Rights and Public Law” in Matthew H Kramer, ed, Rights, Wrongs and Responsibilities (Palgrave Macmillan, 2001) 1, DOI: .

80. For a rule that is in substance similar to what I am proposing (though he uses different terms), see Lord Mance, “Justiciability” (2018) 67 Inti & CLQ 739 at 756. I do not intend to rule out the possibility that a similar rule applies in public law, as suggested by Erwin Chemerinsky. See “A Unified Approach to Justiciability” (1991) 22 Conn L Rev 677. Chemerinsky observes that “if the constitutional or statutory provision creates a legal right in the individual, then he or she should be able to sue to vindicate that right” (ibid at 698). However, Chemerinsky adds that other rules are needed to make sense of public law justiciability. While claims under the Charter and similar instruments have a rights-based structure that fits with the rule I have stated in the main text, it would require further investigation to determine whether all of public law would fit.

81. Dawson v Rexcraft Storage and Warehouse Inc, 1998 CanLII 4831 at para 10 (ONCA); Wall v Judicial Committee of the Highwood Congregation of Jehovah’s Witnesses, 2016 ABCA 255 at para 82 [Wall CA].

82. See Shergill, supra note 8 at para 43.

83. 2019 SCC 4.

84. Ibid at para 93.

85. The fact that this is also true of Liau’s Private Law Standing Rule is suggestive. Liau, supra note 6. Both rules tie adjudicability to the existence of a legal right. This suggests that private law may have a more general idea of which claims should be decided from which both the Standing Rule and the Justiciability Rule follow. However, I leave this as a conjecture; pursuing it would take us far afield.

86. Chan, supra note 15 at 220.

87. Ibid at 221-22 [emphasis in original]. See also Patrick Hart, “Justice for W(all): Judicial Review and Religion” (2017) 43 Queen’s LJ 1 at 9-11.

88. Ibid at 10 [emphasis in original]. Hart proposes that the principle from Dunnet is not “the sole measure in determining justiciability” but rather “one factor relevant to…whether a court should intervene” (ibid at 27 [emphasis in original]). See also Chan, supra note 15 at 221.

89. See Shergill, supra note 8. The court stated that “once the forbidden area is identified, the court may not adjudicate on the matters within it” (ibid at para 42).

90. This claim is characteristic of Kantian private law theories. See Ernest Weinrib, The Idea of Private Law (Oxford University Press, 2012) at 82; Arthur Ripstein, Force and Freedom (Harvard University Press, 2009) at 16; Immanuel Kant, “The Metaphysics of Morals” in Mary J Gregor, ed, Practical Philosophy, translated by Mary J Gregor (Cambridge University Press, 1996) 353 at 389, DOI: .

See also FA Mann, Foreign Affairs in English Courts (Oxford University Press, 1986), ch 9, DOI: .

106. See Nevsun, supra note 104 at paras 296, 300. Côté J seemed to suggest that the courts have a special mandate to consider international law in public law cases which they lack in private law. But no such mandate is necessary if answering an international law question is necessary for resolving private rights.

Another point of uncertainty which arises on the ordinary understanding is precisely where in the duty of care analysis the policy immunity is considered. See Nelson (City) v Marchi, 2021 SCC 41 at paras 33-36 [Marchi].

112. 1989 CanLII 81 (SCC).

113. See St-Hilaire v Canada (Attorney General), 2001 FCA 63 at paras 40-42.

114. This continues to hold under the Civil Code of Quebec. See Entreprises Sibeca Inc v Frelighsburg (Municipality), 2004 SCC 61 at para 27. See also Kosoian v Société de transport de Montréal, 2019 SCC 59. It states: “The purpose of this immunity is to preserve the latitude that a legal person established in the public interest must have in order to make policy decisions in the interests of the community” (ibid at para 107).

115. Marchi, supra note 111 at para 42. See also Kamloops, supra note 108, which states that the Anns principle “prevents the courts from usurping the proper authority of elected representatives and their officials” at 25. See also Rowling v Takaro Properties Ltd, [1988] AC 473 at 501 (JCPC UK).

116. More specifically, the Court is prevented from adjudicating the claim in private law. The plaintiff might still be entitled to challenge the policy decision in administrative law (e.g., for bad faith). See especially Just v British Columbia, 1989 CanLII 16 at 1239 (SCC).

117. This is not ruled out by the Supreme Court of Canada’s recent rejection of a proposal by Stratas JA. For that proposal, see Paradis Honey Ltd v Canada (Attorney General), 2015 FCA 89. For the rejection, see Marchi, supra note 111 at para 41. Stratas JA was proposing that private law does not apply at all to the state; I am proposing that the policy immunity determines when private law applies.

119. Cases in which a private law claim is blocked by Parliamentary privilege—for example, where a defamation claim is rejected because it would intrude on freedom of speech in Parliament—might be an additional example. See Shergill, supra note 8 at para 42. See also Mance, supra note 80 at 751. The dismissal of claims which have passed their limitation period is structurally similar to these exceptions, but it depends on the timing of the claim rather than its content. As a result, I would not class it among the exceptions to the rule. For discussion of expired claims, see Samuel Beswick, “Retroactive Adjudication” (2020) 130 Yale LJ 276 at 340.
