CITY OF RIO RANCHO,

Defendant.

ORDER ON MOTION TO DISMISS

THIS MATTER is before the Court on Defendant City of Rio Rancho’s Motion to Dismiss (Doc. 22). Also before the Court are Plaintiffs’ Motion for Leave to Supplement Response in Opposition (Doc. 55), Defendant’s Motion for Recovery of Costs (Doc. 21), and Defendant’s Motion for Sanctions (Doc. 59). The Court grants Plaintiffs’ Motion for Leave to Supplement Response, and denies Defendant’s Motion for Recovery of Costs and Motion for Sanctions. The Court has reviewed the parties’ submissions, the record, and the relevant law, and for the reasons below, the Motion to Dismiss is granted. BACKGROUND This case arises out of several ordinances passed by the City of Rio Rancho in recent years. Plaintiffs are residents of Rio Rancho who allege that the City violated its own procedural requirements by failing to identify a sponsor for proposed legislation in City Council agendas, meeting minutes, and signed ordinances. While it is difficult to discern the precise claims, Plaintiffs ultimately seek to enjoin enforcement of five City ordinances as unlawfully enacted. Plaintiffs challenge Ordinance O5, which imposes a lodger’s tax on short-term rental stays; Ordinance O7, which adjusts water and wastewater rates; Ordinance O8, which concerns municipal judge salaries; Ordinance O18, which concerns mayor and city councilor salaries; and Ordinance O22, which regulates short-term rentals.1 See Doc. 1 ¶ 30, Ex. C. In June 2025, Plaintiffs filed a complaint and motion for temporary restraining order in the 13th Judicial District Court, seeking to enjoin enforcement of the challenged ordinances. They now seek federal judicial intervention because the state court did not issue a ruling prior to certain

of the challenged ordinances going into effect. The complaint contains two counts: Count I asserts violations of Plaintiffs’ procedural due process rights under the Fourteenth Amendment; Count II asserts violations of the principle of consent of the governed. The City moves to dismiss for lack of subject matter jurisdiction and for failure to state a claim. The City argues that Plaintiffs’ attempt to enjoin enforcement of tax ordinances is barred by the Tax Injunction Act; that Plaintiffs’ claims rely on an misinterpretation of the Governing Body Rules of Civil Procedure and the complaint fails to allege an actual violation by the City; that Plaintiffs cannot allege a constitutional violation even if the City failed to follow the Governing Body Rules of Civil Procedure; and that Plaintiffs lack standing to bring this action.

LEGAL STANDARDS Defendant first moves to dismiss for lack of jurisdiction. Subject matter jurisdiction is analyzed under Fed. R. Civ. P. 12(b)(1). Ruiz v. McDonnell, 299 F.3d 1173, 1180 (10th Cir. 2002). A Rule 12(b)(1) motion may make a facial attack on the complaint’s allegations as to the existence of subject matter jurisdiction, or go beyond allegations in the complaint and challenge the facts upon which subject matter jurisdiction is based. Stuart v. Colo. Interstate Gas Co., 271 F.3d 1221,

1 Plaintiffs also attach “randomly selected ordinances from 2022, 2023, and 2024” (see Doc. 1, Ex. B), alleging the City similarly failed to comply with the required procedures in passing these ordinances. However, Plaintiffs state that they are not seeking injunctive or compensatory relief with respect to these ordinances. See Doc. 1 ¶ 23 (“Plaintiffs seek to invalidate only three recently enacted ordinances that are actively being enforced after enforcement date of July 1,2025 [and] two ordinances that will be effective July 1, 2026 […] While hundreds of similarly flawed ordinances have been identified, Plaintiffs are not seeking to overturn them all, recognizing the complexity and potential disruption such action could cause.”). 1225 (10th Cir. 2001). Where the moving party raises a facial attack on the allegations of subject matter jurisdiction, the Court presumes the allegations contained in the complaint to be true. Ruiz, 299 F.3d at 1180. Defendant also seeks to dismiss this case under Fed. R. Civ. P. 12(b)(6). To survive a motion to dismiss under Rule 12(b)(6), a complaint must allege “enough facts to state a claim to

relief that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007). Facial plausibility exists “when the pleaded factual content allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 663 (2009). A claim that fails to meet this standard must be dismissed. See Twombly, 550 U.S. at 570. The sufficiency of a complaint is a question of law. Smith v. United States, 561 F.3d 1090, 1098 (10th Cir. 2009). In resolving a Rule 12(b)(6) motion, the Court must accept all well-pled factual allegations as true, view them in the light most favorable to the non-moving party, and draw all reasonable inferences in the plaintiff's favor. See Tellabs, Inc. v. Makor Issues & Rts.,

Ltd., 551 U.S. 308, 322 (2007). The Court’s review is generally confined to the four corners of the pleading. See Mobley v. McCormick, 40 F.3d 337, 340 (10th Cir. 1994). However, the Court need not accept conclusory or unsupported allegations. Dunn v. White, 880 F.2d 1188, 1190 (10th Cir. 1989). Rather, the complaint must provide “reason to believe that this plaintiff has a reasonable likelihood of mustering factual support for these claims.” Ridge at Red Hawk, LLC v. Schneider, 493 F.3d 1174, 1177 (10th Cir. 2007). Finally, when a party proceeds pro se, the Court construes that party’s pleadings liberally and holds them “to a less stringent standard than [that applied to] formal pleadings drafted by lawyers.” Hall v. Bellmon, 935 F.2d 1106, 1110 (10th Cir. 1991). If the Court can reasonably read the pleadings to state a valid claim on which a pro se plaintiff could prevail, it should do so despite the plaintiff’s failure to cite proper legal authority, confusion of legal theories, or unfamiliarity with pleading requirements. Id. The Court does not, however, assume the role of advocate for the pro se litigant, and pro se status does not excuse the obligation of any litigant to
