Filed:

Justice Beth Baker delivered the Opinion of the Court. ¶1 Montanans Against Irresponsible Densification, LLC (MAID) facially challenged the constitutionality of several zoning and land use bills enacted during the 2023 legislative session. The State of Montana and several intervenors defended the new laws. The Eighteenth Judicial District Court entered a declaratory judgment, concluding that the challenged housing reform bills do not violate the constitutional right to equal protection and did not supplant private restrictive covenants. It enjoined several sections that the court determined violated Montana’s constitutional right to participate. The parties appeal and cross-appeal the District Court’s rulings. We consider the following restated issues on appeal:

1. Do MAID’s claims that the Montana Land Use Planning Act (MLUPA) violates Montanans’ right to participate present a justiciable controversy?

2. Do the challenged laws facially violate the public’s constitutional right to participate in site-specific land use decisions?

3. Do the challenged land use statutes violate the right to equal protection by irrationally and detrimentally burdening certain classes of citizens?

¶2 We agree that MAID’s challenges to the MLUPA’s public participation provisions are justiciable. We reverse the District Court’s conclusion that the MLUPA facially violates the constitutional right to participate. We affirm the District Court’s determination that the housing reform statutes do not violate the right to equal protection. We vacate its declaratory ruling on private restrictive covenants as nonjusticiable.

FACTUAL AND PROCEDURAL BACKGROUND ¶3 The 2023 Montana Legislature passed a package of bipartisan housing reform bills related to zoning and land use planning, aimed at addressing Montana’s housing problems. Montanans Against Irresponsible Densification, LLC v. State, 2024 MT 200, ¶ 21, 418 Mont. 78, 555 P.3d 759 (MAID I). Relevant here, the package included:

 Senate Bill 528, 2023 Mont. Laws ch. 502, codified as § 76-2-345, MCA, requiring that all municipalities “adopt regulations . . . that allow a minimum of one accessory dwelling unit [(ADU)] by right on a lot or parcel that contains a single-family dwelling.”

 Senate Bill 323, 2023 Mont. Laws ch. 445, codified as §§ 76-2-304(3), (5), -309, MCA, amending § 76-2-304, MCA, to require cities with a population of at least 5,000 residents to allow duplexes where single-family dwelling is permitted.

 Senate Bill 382, 2023 Mont. Laws ch. 500, codified as Title 76, chapter 25, MCA, creating the Montana Land Use Planning Act (MLUPA), which applies to municipalities equal to or greater than 5,000 located in counties with populations at or exceeding 70,000. The MLUPA requires communities that meet this population benchmark to substantially change their subdivision and zoning regulations and long-range community planning. The MLUPA also defines public participation in this process.

¶4 In December 2023, MAID filed a complaint alleging several facial challenges to the constitutionality of the 2023 housing reform bills. A Montana limited liability company, MAID is made up of property owners who live in single-family neighborhoods in

Whitefish, Bozeman, Billings, Missoula, Great Falls, Columbia Falls, and Kalispell. MAID’s principal contention was that the housing reform unfairly burdened single-family residential neighborhoods with urban growth and accomplished this by—among other things—undermining the MLUPA-municipality citizens’ right to know and participate during the land-use planning and approval process. MAID prayed for declaratory relief and a preliminary and permanent injunction. 1 ¶5 Finding a potential for irreparable harm once they went into effect, the District Court preliminarily enjoined the implementation and enforcement of two 2023 housing reform bills on December 29, 2023. The State appealed. This Court, in MAID I, reversed the District Court’s decision and remanded for further proceedings. MAID I, ¶ 23. On remand, Shelter WF, the Montana League of Cities and Towns (the League), David Kuhnle, and Clarence Kenck intervened with leave of court to defend the housing reform statutes. Following its consideration of the parties’ motions and cross-motions to dismiss and for summary judgment, the District Court issued its decision on the motions now before this Court.

1 Senate Bill 245, 2023 Mont. Laws ch. 499, codified as § 76-2-304(4), MCA, requires that urban municipalities with population of at least 5,000 allow multiple-unit dwelling and mixed-used developments in commercial zones under certain conditions. In MAID’s second motion for summary judgment and on appeal, it claims to continue to challenge the constitutionality of § 76-2-304(4), MCA, without elaboration. MAID’s arguments are premised on the rights of homeowners located in single-family neighborhoods. MAID does not develop its claim that § 76-2-304(4), MCA—a statute addressing commercial zones—violates the constitution under its argument that the housing reform statutes eliminate single-family zoning. We, therefore, do not address its constitutionality on appeal. McCulley v. Am. Land Title Co., 2013 MT 89, ¶¶ 19-20, 369 Mont. 433, 300 P.3d 679 (“[W]e are not obligated to develop arguments on behalf of parties to an appeal, nor are we to guess a party’s precise position, or develop legal analysis that may lend to his position.” (citations omitted)).
