Can counties challenge municipal annexations without statutory standing? Summit County v. Hideout Explained

The Utah Supreme Court’s decision in Summit County v. Hideout provides important guidance on standing requirements for challenging municipal annexations under Utah’s Declaratory Judgment Act.

Background and Facts

In 2020, the Utah Legislature briefly enacted H.B. 359S1, which allowed municipalities to annex non-contiguous areas without county consent for just over 100 days. During this window, the Town of Hideout annexed approximately 350 acres in Summit County. After obtaining written consent from property owners and following statutory procedures, Hideout received certification from the Lieutenant Governor. Summit County promptly filed suit challenging the annexation on five grounds, including violations of LUDMA, OPMA, and the annexation code’s publication requirements.

Key Legal Issues

The central issue was whether Summit County had standing to challenge the annexation under the Declaratory Judgment Act. The district court found standing based on various statutes including CLUDMA, LUDMA, and OPMA, as well as the doctrine of public interest standing. Hideout argued Summit County lacked the required legally protectible interest in the controversy.

Court’s Analysis and Holding

The Utah Supreme Court reversed, applying the four-part test from Jenkins v. Swan for Declaratory Judgment Act standing. The Court focused on the third requirement: whether Summit County had a legally protectible interest in the controversy. Following Miller v. Weaver, the Court explained that when declaratory judgment claims are rooted in statute, a legally protectible interest must come from an express or implied statutory right of action.

The Court found that the annexation code itself provided no right of action for counties, particularly since H.B. 359S1 expressly permitted annexation “without the consent of the county.” The various other statutes Summit County cited—including CLUDMA’s purpose statements and general enforcement provisions—were insufficient because they either stated broad purposes rather than creating rights of action, or provided only procedural authority unrelated to challenging municipal annexations.

Importantly, the Court also rejected Summit County’s alternative claim of public interest standing. Citing McKitrick v. Gibson, the Court held that public interest standing cannot cure deficiencies when a plaintiff is excluded from the relevant statutory scheme.

Practice Implications

This decision reinforces that standing analysis under the Declaratory Judgment Act requires careful identification of specific statutory rights of action. Practitioners cannot rely on broad statutory purposes, general enforcement authority, or procedural provisions to establish the necessary legally protectible interest. The ruling also clarifies that public interest standing cannot circumvent statutory exclusions—if the legislature excluded a party from a statutory scheme, that party cannot use alternative standing theories to gain access to the courts.
