delivered the Opinion of the Court.
¶1 Denturist Association of Montana, on behalf of Carl Brisendine, appeals
¶2 We address the following issue:
Did the District Court err in concluding Brisendine’s claims were barred by res judicata?
PROCEDURAL AND FACTUAL BACKGROUND
¶3 The Denturist Association of Montana (Association), on behalf of denturist Carl Brisendine (Brisendine), filed suit against the Board of Dentistry (Board), challenging the validity of A.R.M. 24.138.2302(1)(j) (Rule J), the latest in a long line of legal disputes between the two. See Board of Dentistry v. Kandarian,
¶4 Included in both Wiser I and Wiser II, either implicitly or explicitly, was the claim that the Board’s promulgation of Rule J was invalid because it conflicted with statute. Wiser II, ¶ 16. The Wiser I plaintiffs — comprised of every denturist in Montana — made their claims “on behalf of the profession of denturitry.” Wiser II, ¶ 18. The Wiser I plaintiffs lost their challenge to the Board’s authority to promulgate rules regulating denturitry. The Wiser II plaintiffs, comprised of a smaller group of denturists, attempted to distinguish themselves from the Wiser I plaintiffs, but the Court saw no distinction in their capacity to challenge the Board’s promulgation of Rule J as individuals rather than as representatives of a group. Wiser II, ¶ 18. The Court barred the Wiser II plaintiffs’ claims on res judicata grounds. Wiser II, ¶ 18.
¶5 In this case, Brisendine’s complaint contains three counts. Count I alleges Rule J is discriminatory and restrains trade in violation of § 37-l-131(l)(a)(ii), MCA, which provides every regulatory board will:
Apply the standards and rules referred to in subsection (l)(a)(i) in a manner that does not discriminate against any person licensed by the board with regard to how the standards and rules are applied to other persons licensed by the board and that does not restrain trade or competition unless necessary to protect public health and safety;
Count I further alleges the Board violated § 37-l-131(l)(a)(ii), MCA, by discriminatorily applying its disciplinary rules: being unduly harsh on denturists while giving leniency to dentists. Counts II and III allege Rule J is invalid because it conflicts with various statutes.
¶6 Brisendine moved for summary judgment on Count II, and the Board filed a cross-motion for summary judgment on all counts. The District Court, citing Wiser I and II, held Brisendine’s claims were barred by res judicata as a matter of law. Brisendine appeals.
STANDARD OF REVIEW
¶7 An order on summary judgment is reviewed de novo, applying the same criteria as the district court. Lorang v. Fortis Ins. Co.,
¶8 A district court’s application of res judicata or collateral estoppel is reviewed de novo. Textana, Inc. v. Klabzuba Oil & Gas,
DISCUSSION
¶9 Did the District Court err in concluding Brisendine’s claims were barred by res judicata?
¶10 A final judgment can have a preclusive effect on future litigation by way of either claim preclusion (res judicata) or issue preclusion (collateral estoppel). See Baltrusch v. Baltrusch,
¶11 Under claim preclusion, a judgment on the merits in a prior suit bars a second suit involving the same parties or their privies based on the same cause of action. Baltrusch, ¶ 15; see also Parklane Hosiery Co. v. Shore,
¶12 Issue preclusion, on the other hand, bars the same parties or their privies from relitigating issues in a second suit that is based upon a different cause of action. Baltrusch, ¶ 15; see also Parklane Hosiery,
¶13 With respect to Count I, Brisendine argues he has no privity with the plaintiffs in Wiser I and II, and that Count I represents an altogether different claim than those presented in either of those cases. With respect to Counts II and III, Brisendine argues only that he has no privity with the plaintiffs in Wiser I and II, conceding the other elements are met. The Board responds that privity exists between the Wiser I and II plaintiffs and Brisendine because the interests between the two are so closely aligned that the Wiser I and 77 plaintiffs were the virtual representatives of Brisendine. We agree with the Board that privity exists, but agree with Brisendine that Count I represents a different cause of action, with a new issue, than present in Wiser I or 77.
¶14 The application of claim or issue preclusion to a party that was not a party in the prior proceeding, otherwise known as nonparty preclusion, conflicts with the “deep-rooted historic tradition that everyone should have his own day in court.” Taylor v. Sturgell,
¶15 Applying the above rules here, we conclude that privity exists between the litigants in Wiser I and 77 and Brisendine. The Wiser I litigants included every denturist in Montana, and they brought their suit “on behalf of the profession of denturitry.” Wiser II, ¶ 18. Even though not a denturist at the time of the earlier litigation, Brisendine’s interests are “closely aligned,” Nordhorn,
¶16 Because privity exists and the other elements of claim preclusion are not contested with respect to Counts II and III, we affirm the District Court’s grant of summary judgment to the Board on those claims on res judicata grounds.
¶17 Count I of the Complaint alleges the Board has engaged in a pattern of systemic discrimination, restraint of trade, and unfair anti-competitive practices in violation of § 37-l-131(l)(a)(ii), MCA. This is an entirely different claim than those made in either Wiser I or II. First, part of Brisendine’s claim here is that the Board has applied its disciplinary rules in a discriminatory fashion by aggressively pursuing perceived violations by denturists, while showing leniency to dentists. This is a highly specific factual claim that includes allegations of misconduct occurring in 2014, an altogether different subject matter than the claims in Wiser I and II. Second, § 37-1-131(1)(a)(ii), MCA, was enacted after Wiser I and II. Although the Denturists
¶18 Affirmed in part, reversed in part, and remanded for further proceedings.
Notes
Brisendine argues that the Denturist Association has associational standing to bring this suit on his behalf because, according to Brisendine, his claims are not barred by res judicata, and thus he has standing to bring the claim, which he may confer on the Denturist Association. Brisendine appears to confuse the concept of standing, which requires an allegation of past, present, or threatened injury, Chipman v. Nw Healthcare Corp.,
