Certiorari as the Exclusive Remedy for Quasi-Judicial Conditional-Use Permit Approvals in Delaware

1. Introduction

Citizens Against Solar Pollution v. Kent County (Del. Mar. 10, 2025) addresses the procedural pathway for challenging a county government’s approval of a conditional-use permit—here, a permit granted by the Kent County Levy Court to FPS Cedar Creek Solar LLC to develop a large solar farm.

The challengers—Citizens Against Solar Pollution (a Delaware unincorporated nonprofit association) and nearby property owners Donald Lee Goldsborough and Kellie Elaine Goldsborough (through trusts) (collectively, “CASP”)—initially sued in the Court of Chancery seeking injunctive relief and a declaratory judgment invalidating the permit approval. The litigation ultimately required the Delaware Supreme Court to resolve three central issues:

  1. Whether the Court of Chancery had subject matter jurisdiction given the availability of a writ of certiorari in Superior Court;
  2. Whether CASP could maintain a declaratory judgment action in Superior Court alongside certiorari review;
  3. The proper scope of certiorari review and whether the Levy Court’s process and written approval were legally sufficient.

2. Summary of the Opinion

The Delaware Supreme Court affirmed (i) the Court of Chancery’s dismissal for lack of subject matter jurisdiction and (ii) the Superior Court’s dismissal of CASP’s declaratory judgment claim and its ultimate affirmance of the permit approval on certiorari review. Key holdings include:

  • Chancery lacks equitable jurisdiction to review a county’s quasi-judicial conditional-use permit approval when a writ of certiorari is available and adequate in Superior Court.
  • A declaratory judgment action cannot be used where an immediately available, adequate remedy (here, certiorari) exists to address the same dispute.
  • On certiorari, courts correct legal errors apparent on the face of the record; they do not reweigh evidence, revisit factual findings, or treat the matter as a direct appeal.
  • A Kent County conditional-use permit approval is a quasi-judicial application of existing law and therefore does not require adoption of an ordinance.

3. Analysis

3.1. Precedents Cited

Delta Eta Corporation v. City of Newark

The Court’s jurisdictional analysis is anchored in Delta Eta Corporation v. City of Newark, which the Supreme Court treated as providing a “thorough analysis” of why certiorari is the proper and adequate vehicle to review quasi-judicial permit approvals. Delta Eta supplies two doctrinal pillars adopted here:

  • Characterization of the governmental act: applying existing zoning law to particular facts is quasi-judicial, not legislative.
  • Adequacy of certiorari: a challenger must show certiorari cannot afford “full and fair relief”; it is not enough to argue that certiorari review is narrower than appellate review.

CASP did not meaningfully distinguish Delta Eta, and the Court declined to depart from it—effectively reaffirming Delta Eta’s framework as the default approach for similar land-use challenges in Delaware.

Dover Hist. Soc'y v. City of Dover Plan. Comm'n

Dover Hist. Soc'y v. City of Dover Plan. Comm'n is cited for the historical and functional understanding of certiorari: it exists to correct errors of law, review proceedings not conducted according to law, and restrain excess of jurisdiction. Dover Historical Society supports the Court’s view that certiorari is a longstanding supervisory tool for quasi-judicial local land-use determinations.

Middlecap Assocs., LLC v. Town of Middletown

Middlecap Assocs., LLC v. Town of Middletown is cited as additional Court of Chancery support for the proposition that when certiorari is available and adequate, Chancery lacks subject matter jurisdiction.

In re COVID-Related Restrictions on Religious Servs.

The Supreme Court relied on In re COVID-Related Restrictions on Religious Servs. for the standard of review: subject matter jurisdiction is reviewed de novo. While not land-use specific, it frames the Court’s appellate posture.

Hampson v. State ex rel. Buckson

On the declaratory judgment issue, the Court applied Hampson v. State ex rel. Buckson, which holds that declaratory judgments are intended to provide a remedy only when no other remedy is available; where an adequate remedy exists, “the other remedy should be followed.” The Supreme Court treated Hampson’s reasoning as directly controlling, rejecting CASP’s attempt to treat declaratory relief and certiorari as co-equal avenues for the same claim.

B.W. Electric, Inc. v. Gilliam-Johnson

CASP invoked B.W. Electric, Inc. v. Gilliam-Johnson to argue that certiorari and declaratory judgment may coexist in one complaint. The Supreme Court distinguished it: in B.W. Electric, the claims were not duplicative because the declaratory claims attacked agency regulations while certiorari reviewed a discrete adjudicatory dismissal. Here, both requested forms of relief targeted the same governmental act—the Levy Court’s permit approval—so declaratory judgment would improperly circumvent the certiorari framework.

Maddrey v. Just. of Peace Ct. 13

Maddrey v. Just. of Peace Ct. 13 is used to reinforce a core limitation: certiorari “is not a substitute for an appeal.” This is crucial to the Court’s rejection of CASP’s efforts to litigate the merits (zoning interpretation, land-use plan conformity, and similar issues) under the guise of certiorari.

Black (as quoted in the Opinion) and Christiana Town Ctr., LLC v. New Castle Cnty. (TABLE)

The Court relied on Black to define the certiorari record and to explain why arguments requiring deep record review would convert certiorari into a de facto appeal. It cited Christiana Town Ctr., LLC v. New Castle Cnty. (TABLE) for the requirement that a quasi-judicial body must state the basis for its decision sufficiently to permit judicial review—supporting the conclusion that the Levy Court’s conditional-approval letter was adequate.

Bay Colony v. Cnty. Council of Sussex Cnty. and Gibson v. Sussex Cnty. Council

These cases appear in the Court’s discussion of legislative vs. quasi-judicial classification across counties, particularly the argument that Sussex County’s zoning scheme may make certain conditional uses more “legislative” in effect. The Supreme Court, adopting Delta Eta’s approach, emphasized that the distinction is applied case-by-case, focusing on the specific special use decision rather than broad generalizations about a county’s zoning architecture.

Geico Gen. Ins. Co. v. Green

Geico Gen. Ins. Co. v. Green is cited for the de novo standard of review for dismissal rulings, structuring the Court’s review of the Superior Court’s declaratory judgment dismissal.

3.2. Legal Reasoning

(a) Chancery Jurisdiction and the “Adequate Remedy at Law” Rule

The Court applied a classic equity principle codified at 10 Del. C. § 342: the Court of Chancery lacks jurisdiction where a sufficient remedy is available at law. CASP attempted to avoid this by emphasizing that it sought equitable relief (injunction) in addition to legal relief. The Supreme Court rejected that framing: the availability of certiorari as an adequate mechanism to challenge the quasi-judicial permit approval defeats Chancery jurisdiction even if the plaintiff pleads equitable remedies.

The critical move is the Court’s acceptance (unchallenged by CASP on appeal) that the permit approval was quasi-judicial. Once the action is quasi-judicial, certiorari becomes the presumptive—and here, adequate—review tool.

(b) Declaratory Judgment as a Residual Remedy

CASP conceded the general principle that declaratory relief is appropriate only when no other remedy exists, but argued that declaratory judgment and certiorari are not mutually exclusive. The Court held otherwise when both target the same underlying dispute: certiorari being adequate and immediately available means declaratory judgment serves no proper function and risks expanding review beyond certiorari’s limits.

(c) The Scope of Certiorari Review: Record- and Law-Focused, Not Merits-Based

The Court reaffirmed the narrow nature of certiorari:

  • It corrects errors of law and procedural irregularities apparent on the face of the record.
  • It does not permit weighing evidence, reconsidering factual findings, or deciding merits questions as on appeal.

This drove two practical outcomes:

  1. Adequate record: The Court rejected CASP’s argument that missing “exhibits” made the record inadequate. Under the Court’s certiorari doctrine, the essential record consists of the initiating document, response (if required), and docket entries. The certified record contained these, and the Superior Court could request exhibits if necessary.
  2. Adequate articulation of reasons: The Levy Court’s conditional-approval letter identified sources (planning commission recommendation and public hearing) and made enumerated findings; the Court deemed this sufficient articulation to permit judicial review.

(d) Ordinance Requirement and the Legislative/Quasi-Judicial Divide

CASP argued that because actions with “force of law” must be adopted as ordinances under 9 Del. C. § 4110(h), the permit approval required an ordinance. The Court rejected this by categorizing the decision as quasi-judicial—an individualized application of existing law rather than a lawmaking act—therefore not requiring an ordinance.

This portion of the opinion reinforces a functional boundary: conditional-use decisions in a zoning framework that authorizes them by district are ordinarily adjudicative implementations of policy, not the creation of policy.

3.3. Impact

(a) Procedural Channeling: Land-Use Challenges Must Generally Proceed by Certiorari

The decision strengthens a predictable procedural rule for Delaware land-use litigation: when a county body acts quasi-judicially in approving a conditional use, challengers should expect that:

  • Chancery will dismiss for lack of jurisdiction if certiorari can address the claim;
  • Declaratory judgment claims cannot be used to broaden the scope of review where certiorari is adequate.

(b) Substantive Consequence: Limited Judicial Review of Permitting Merits

Because certiorari is narrow, challengers face a structural constraint: arguments that hinge on disputed facts, evidentiary weight, or detailed interpretation of planning documents often will not be reached unless they can be reframed as facial legal error or procedural irregularity on the record. The opinion thus incentivizes litigants to:

  • Focus on jurisdictional defects, procedural failures, or absence of a reviewable basis;
  • Build a record emphasizing clear legal noncompliance that appears on the face of the decision materials.

(c) Government Practice: Minimal-but-sufficient Written Reasons

The Court signaled that local bodies need not draft extensive adjudicatory opinions. A letter that states reliance on identified inputs (reports, hearings) and lists findings can satisfy the requirement to state a basis for review. Practically, this may influence counties and municipalities to standardize decision letters to satisfy certiorari scrutiny.

4. Complex Concepts Simplified

  • Writ of certiorari: A limited form of judicial review where a higher court checks whether a lower tribunal or government body acted within its authority and followed the law, based primarily on what appears in the official record—not a full appeal on the merits.
  • Quasi-judicial act: A government decision that applies existing rules to specific facts (like deciding whether one permit applicant meets zoning requirements).
  • Legislative act: A government decision that makes or changes general rules (like amending a zoning ordinance).
  • Adequate remedy at law: If the law courts can provide a sufficient process to address the complaint (here, certiorari in Superior Court), equity (Chancery) generally will not intervene.
  • Declaratory judgment: A court declaration of legal rights or status, typically used when parties need clarity and no other immediate and adequate remedy exists to resolve the dispute.
  • “Face of the record” review: The reviewing court looks at the formal record materials (initiating filing, response if required, docket entries, and the decision documents) rather than taking evidence, retrying facts, or reconsidering the merits.

5. Conclusion

Citizens Against Solar Pollution v. Kent County consolidates and operationalizes a clear procedural principle in Delaware land-use law: quasi-judicial conditional-use permit approvals are reviewed by writ of certiorari, not by equitable or declaratory judgment litigation designed to obtain broader appellate-style review. The opinion further confirms that certiorari’s scope is narrow, that the required record is limited, and that a county’s quasi-judicial permit approval does not require enactment of an ordinance.

The broader significance lies in the Court’s insistence on remedy discipline and institutional role: when the law provides a specific, historically bounded supervisory writ for quasi-judicial local decisions, litigants cannot expand judicial review by repackaging the dispute as equity or declaratory judgment—especially where doing so would transform certiorari into an appeal on the merits.
