Ordinary Bureaucratic Delay and Discretionary Land-Use Approvals Do Not Create Due Process or Takings Liability; “Cat’s Paw” Does Not Substitute for Monell Policymaker Proof

1. Introduction

In Rubicon Real Estate Holdings v. City of Pontiac, Michigan (6th Cir. June 18, 2026), Rubicon Real Estate Holdings, LLC (“Rubicon”), its managing member Joseph Brown, and Brown’s separate design firm Browne Design Consultants, LLC (“BDC”) sued the City of Pontiac and interim city clerk Garland S. Doyle under 42 U.S.C. § 1983.

The dispute arose from Rubicon’s attempt (2019–2021) to redevelop the Glenwood Plaza property in Pontiac into a commercial project that would include medical marijuana cultivation and processing tenants. Rubicon alleged that Pontiac’s bureaucracy—especially Doyle’s handling of tenant permit applications and a zoning “overlay district” interpretation—delayed approvals, caused tenants to abandon the project, and ultimately collapsed financing. Separately, Brown and BDC alleged First Amendment retaliation: that Pontiac’s mayor later pressured another developer to cut ties with BDC because of Rubicon’s earlier lawsuit.

The key constitutional issues were: (i) whether delays and discretionary licensing/zoning hurdles created a protected property entitlement for procedural/substantive due process; (ii) whether delay amounted to a compensable taking; (iii) whether a “class-of-one” equal protection claim could be shown without strong comparator proof and “stark outlier” evidence; and (iv) whether municipal liability existed under Monell v. Dep’t of Soc. Servs. for the alleged actions of Doyle and the mayor—particularly whether a “cat’s paw” theory can bridge the Monell gap.

2. Summary of the Opinion

The Sixth Circuit (Readler, J.) affirmed summary judgment for all defendants. The court held:

  • Due Process: Neither Rubicon nor its prospective tenants had a Fourteenth Amendment property entitlement to operate medical marijuana businesses at the site because the relevant zoning, SEP, and licensing decisions remained discretionary under Pontiac ordinances. Without a cognizable property interest, due process claims fail.
  • Takings: Even assuming Rubicon’s ownership interest sufficed, the alleged permit/zoning delay did not approach the “extraordinary” delay required to constitute a regulatory taking. Ordinary administrative lag—even frustrating—does not trigger compensation.
  • Equal Protection (class-of-one): Rubicon failed to produce comparator evidence showing it or its tenants were treated as a “stark outlier” relative to similarly situated applicants; circumstantial evidence of intentional irrational discrimination was insufficient.
  • Municipal liability: With no underlying constitutional violation by Doyle, the City could not be liable on Rubicon’s due process/takings/equal protection theories. As to Brown/BDC’s retaliation claim, the mayor was not a final policymaker for zoning approvals (the City Council was), and the court rejected using “cat’s paw” as a substitute for Monell causation/policymaker requirements.

3. Analysis

3.1 Precedents Cited (and How They Drive the Result)

A. Summary judgment and evidentiary burdens

  • Walden v. Gen. Elec. Int'l, Inc. and Chancellor v. Geelhood: Frame de novo review and the Rule 56 requirement that the nonmovant produce specific, probative evidence of a genuine dispute.
  • Matsushita Elec. Indus. Co. v. Zenith Radio Corp.: Reinforces that the nonmovant must present “specific facts” beyond conjecture.
  • Hall v. Navarre: Treats the movant’s initial production burden as modest; once asserted there is no record evidence of a required element (e.g., comparators), the plaintiff must come forward with proof.

B. Standing (prudential vs Article III) and traceability in downstream economic injury

  • Warth v. Seldin and Kowalski v. Tesmer: Supply the third-party standing rule (generally, assert your own rights) and the “close relationship + hindrance” test—though the panel treats this as forfeitable where not raised.
  • June Med. Servs. LLC v. Russo (and the discussion of Dobbs v. Jackson Women's Health Org.): Used to explain third-party standing as prudential (and thus forfeitable), while noting contrary views.
  • United States v. Knipp (and Fair Elections Ohio v. Husted): Supports forfeiture of prudential standing arguments and the limits of sua sponte standing enforcement when Article III is implicated.
  • Ass'n of Am. Physicians & Surgeons v. FDA, Burt v. Playtika, Ltd., and FDA v. All. for Hippocratic Med.: Re-center Article III as jurisdictional and apply the injury/traceability/redressability trilogy.
  • Diamond Alternative Energy, LLC v. EPA: Critical to traceability where plaintiff is not the direct object of regulation; the court uses “commonsense economic inference” to conclude that interference with a tenant’s licensing can predictably cause landlord economic harm.
  • Czyzewski v. Jevic Holding Corp.: Confirms economic injury is concrete and damages can redress it.

C. Due Process: property entitlement requires limits on discretion

  • Daniels v. Williams: Distinguishes process-based due process from substantive due process conceptions; either way, a protected interest is required.
  • Bd. of Regents of State Colls. v. Roth: The lodestar—no protected property interest without a “legitimate claim of entitlement” grounded in state law rather than a unilateral expectation.
  • Town of Castle Rock v. Gonzales: If officials may grant/deny in their discretion, there is no entitlement (and thus no due process property interest).
  • Med Corp. v. City of Lima: No property interest absent an “explicit guarantee.”
  • Silver v. Franklin Twp. Bd. of Zoning Appeals and Biser v. Town of Bel Air: Zoning regimes that turn on broad, subjective criteria (“general welfare,” “desirability”) preserve discretion and defeat entitlement claims.
  • Williams v. City of Detroit: Reaffirms that retained discretion blocks a cognizable entitlement.
  • EJS Props., LLC v. City of Toledo and Lifestyle Cmtys., Ltd. v. City of Worthington: A discretionary approval can sometimes create a property interest, but not when additional discretionary authorizations remain; “minimum thresholds” do not equal entitlement.
  • Triomphe Invs. v. City of Northwood and Braun v. Ann Arbor Charter Township: Reject the argument that mere land ownership supplies the required due process property interest in a desired land use; the interest must be in the specific approval/use.
  • Hearts Bluff Game Ranch, Inc. v. United States: Reliance on government representations in the hope of receiving a discretionary benefit does not create a compensable entitlement.
  • Green Genie, Inc. v. City of Detroit: Used both for marijuana-regulation context and, later, for the evidentiary rigor required in class-of-one claims.

D. Takings: delay is rarely a taking unless “extraordinary”

  • Novak v. Federspiel and Sheetz v. County of El Dorado: Provide the basic Fifth Amendment takings framework (applied to states through the Fourteenth).
  • Puckett v. Lexington-Fayette Urb. Cnty. Gov't: Takings claim requires a cognizable property interest plus a “taking” without compensation.
  • Andrews v. City of Mentor: Land ownership does not automatically establish the takings “property interest” for all claimed sticks in the bundle; may require state-law “background principles” analysis.
  • Knight v. Metro. Gov't of Nash. & Davidson Cnty.: Frames takings doctrine around the “bundle of rights.”
  • Agins v. City of Tiburon (with the caveat that it was “abrogated on other grounds by Lingle v. Chevron U.S.A. Inc.): Supplies the key delay principle: ordinary permitting delays are an “incident of ownership;” only “extraordinary” delays might implicate the Takings Clause.
  • Tahoe-Sierra Pres. Council, Inc. v. Tahoe Reg'l Plan. Agency: Explains why compensation for routine delays would make government unworkable; the panel contrasts Rubicon’s short delay with the kind of long moratoria debated in Tahoe-Sierra.
  • Norton v. Village of Corrales: Reinforces federal-court reluctance to act as a super zoning board/timekeeper over local processes.
  • Richmond Rd. Partners, LLC v. City of Warrensville Heights: Provides the Sixth Circuit’s multi-factor approach to “extraordinary” delay (length, bad faith, plaintiff-caused delay) and observes that even a year in a “bureaucratic world” is not extraordinary.
  • Wyatt v. United States: Offers comparative benchmarks; multi-year delays have been “condoned” as non-takings.
  • U.S. ex rel. Wall v. Circle C Constr., LLC: Defines bad faith as more than an honest mistake—requires a sinister motive; used to reject imputing bad faith to Doyle.
  • Raceway Park, Inc. v. Ohio: Investment-backed expectations must be “reasonable,” especially in heavily regulated land-use contexts.

E. Equal Protection (class-of-one): comparators and “stark outlier” proof

  • Village of Willowbrook v. Olech: Establishes the class-of-one test (intentional differential treatment + no rational basis).
  • Green Genie, Inc. v. City of Detroit: Tightens step one—mere differential treatment is not enough; plaintiffs need circumstantial evidence showing a “stark outlier” compared to consistent favorable treatment of similarly situated comparators.
  • SECSYS, LLC v. Vigil: Source of the “stark outlier” formulation adopted by Green Genie.
  • Loesel v. City of Frankenmuth and Anders v. Cuevas: Demand a “relevant similarity” analysis grounded in context; comparators must match on the features that plausibly explain different outcomes.
  • Andrews v. City of Mentor (Larsen, J., separate writing): Emphasizes that plaintiffs must prove both sides of the comparator equation—what happened to them and what happened to similarly situated others.
  • Stemler v. City of Florence: Provides the presumption of regularity for official conduct; plaintiffs need “clear evidence” to overcome it.
  • EJS Props., LLC v. City of Toledo: Warns that time/context gaps can reflect policy evolution, not discrimination.

F. Municipal liability: Monell, final policymaker, and rejection of cat’s paw

  • Connick v. Thompson, Monell v. Dep't of Soc. Servs., and City of Canton v. Harris: Anchor the principle that municipalities are liable only for their own policies/customs, not respondeat superior.
  • Gambrel v. Knox County and Thomas v. City of Chattanooga: Identify the four routes to show a municipal policy/custom (legislation; final decisionmaker act; inadequate training/supervision; custom of tolerance/acquiescence).
  • Pineda v. Hamilton County and Bd. of Cnty. Comm'rs of Bryan Cnty. v. Brown: Emphasize “rigorous” causation; the policy/custom must be the “moving force.”
  • Andrews v. Wayne County: Reinforces the causation burden.
  • Dibrell v. City of Knoxville: Absent an underlying constitutional violation, municipal liability fails for claims derivative of an employee’s conduct.
  • Bible Believers v. Wayne County and Pembaur v. City of Cincinnati: A single act can be municipal policy only if performed by an official with final policymaking authority over the subject matter.
  • Flagg v. City of Detroit: Final authority requires decisions be “final and unreviewable” and not constrained by superior officials’ policies; veto power that can be overridden does not suffice.
  • Manor Healthcare Corp. v. Lomelo: Persuasive analogy—mayor not final zoning policymaker where council can override.
  • Staub v. Proctor Hosp. and Marshall v. The Rawlings Co.: Define “cat’s paw” in employment law; invoked here only to be rejected in the Monell setting.
  • Jones v. City of Hutto and Waters v. City of Chicago: Support the court’s skepticism that “cat’s paw” (agency-based imputation) is compatible with Monell’s bar on respondeat superior.
  • Kovalchuk v. City of Decherd: Reiterates “moving force” and “deliberate conduct” requirements for municipal causation.
  • Burgess v. Fischer: “After-the-fact approval” of a single subordinate violation is insufficient; otherwise municipalities become vicariously liable.
  • Scottsdale Ins. Co. v. Flowers: Permits reply briefing to address arguments raised in a response.
  • United States v. 15 Bosworth St.: “Bedrock rule” that insufficient evidence resolves against the party with the burden—applied to plaintiffs’ failure to prove a Monell element.

3.2 Legal Reasoning

A. The court’s core move on Due Process: discretion defeats entitlement

The due process holding turns on a familiar but often outcome-determinative hinge: whether local law meaningfully limits official discretion such that an applicant has a “legitimate claim of entitlement” under Bd. of Regents of State Colls. v. Roth. The court treated Pontiac’s medical-marijuana regime as structurally discretionary at multiple levels—rezoning, SEP approval, and licensing compliance review—using broad criteria like neighborhood “impact” and “public welfare,” plus extensive application requirements and inspections.

Even though Rubicon obtained an industrial rezoning and executed a Conditional Rezoning Agreement, the panel treated those as clearing only one discretionary hurdle, leaving other discretionary decisions outstanding. That prevented the rezoning from crystallizing into a due process property entitlement to the ultimate desired use (marijuana operations and attendant rents). The opinion’s emphasis on “remaining steps” and continuing discretion operationalizes the Sixth Circuit’s line between (i) a granted, final approval that might create an entitlement and (ii) interim approvals that remain contingent.

B. The takings analysis: delay claims are exceptional, not routine

For takings, the panel assumed (without deeply analyzing state “background principles”) that Rubicon’s ownership could supply the relevant interest, then disposed of the claim on the “taking” element: a delay only becomes a taking if “extraordinary” under Agins v. City of Tiburon and its progeny. The panel assessed:

  • Length: Doyle’s disputed overlay-district stance plausibly delayed matters only a few months; even the longer timeline (2019–2021) did not approach thresholds courts treat as extraordinary.
  • Bad faith: No evidence suggested “sinister motive” under U.S. ex rel. Wall v. Circle C Constr., LLC; at most, an arguable legal mistake.
  • Plaintiff-caused delay/deficiencies: Rubicon’s SEP timing and the tenants’ application deficiencies contributed materially.

The opinion also rejected an “economic wipeout regardless of length” framing because the record did not show the property became worthless or that the short delay was the but-for cause of collapse (as opposed to broader, cumulative timing and financing realities). Investment-backed expectations had to be “reasonable” in the context of complex land-use regulation (Raceway Park, Inc. v. Ohio), and ordinary time for administrative and judicial review was treated as part of the baseline.

C. Class-of-one equal protection: the comparator requirement is not a formality

The panel’s class-of-one analysis is evidence-centered. Under Village of Willowbrook v. Olech, a plaintiff must show intentional differential treatment without rational basis. But consistent with Green Genie, Inc. v. City of Detroit, the court demanded more than “someone else got treated differently”: the plaintiff must present circumstantial evidence of intentional irrationality—i.e., the plaintiff is a “stark outlier” compared with similarly situated comparators.

Rubicon failed at step one because it did not identify comparators similarly situated on the salient features (medical-marijuana licensing timing, outside-overlay posture, application completeness, etc.). The court also turned Rubicon’s attempt to rely on other rejection letters against it: those letters suggested Doyle applied similar deficiency enforcement to others, undermining the claim that Rubicon’s tenants were singled out for hostile or irrational treatment.

D. Monell and the mayor-retaliation claim: final policymaker and causation do the work

For Brown and BDC’s retaliation theory, the court resolved the case on municipal liability rather than the First Amendment merits. It assumed arguendo a retaliation claim could exist but found no Monell hook:

  • No final policymaker: Pontiac’s City Council had final authority for rezoning; the mayor’s veto was overrideable, defeating “final and unreviewable” status under Flagg v. City of Detroit.
  • No council adoption/ratification: At most, one councilmember knew of the mayor’s alleged statement; that is not a municipal “policy.” Under Burgess v. Fischer, after-the-fact approval of a single incident is not enough.
  • Cat’s paw rejected: The court refused to extend Staub v. Proctor Hosp.-style imputation into Monell, reasoning it would reintroduce respondeat superior through agency principles and dilute the “moving force” and “deliberate conduct” constraints emphasized in Kovalchuk v. City of Decherd.

3.3 Impact

A. Land-use and cannabis-permitting litigation: federal constitutional claims face a higher bar

The opinion reinforces that, even in politically and economically charged areas like cannabis licensing, federal constitutional claims are not a general remedy for bureaucratic friction. Discretion-heavy municipal schemes—especially those using public-welfare criteria and multi-step approvals—will often defeat due process “entitlement” theories at the threshold.

B. Takings-by-delay: the Sixth Circuit signals an “extraordinary” threshold with real teeth

By emphasizing that even many-month delays (and arguably even longer delays) are typically non-compensable, the court continues to confine takings-by-delay to rare, extreme cases. Plaintiffs should expect to prove: (i) unusually long delay, (ii) unjustified or bad-faith obstruction, (iii) minimal applicant contribution, and (iv) concrete evidence of severe deprivation (not just project failure).

C. Class-of-one equal protection: comparator proof is the critical choke point

The decision underscores that class-of-one claims live or die on comparator evidence and context. General allegations of “slow-walking” or “hostility” without a record of similarly situated applicants treated consistently better will not survive summary judgment.

D. Municipal liability: “cat’s paw” is unlikely to become an end-run around Monell

Perhaps the most broadly exportable takeaway is structural: courts will be wary of importing imputation doctrines (developed for private employment relationships) into Monell. Where decisionmaking authority is separated (e.g., mayor vs. council), plaintiffs must prove the municipality itself—through final policymakers or established customs—was the moving force.

4. Complex Concepts Simplified

  • Property interest (Due Process) vs. property interest (Takings): Due process asks whether state/local law gives you an entitlement (something officials must grant if criteria are met). If officials have meaningful discretion, you likely have no due process property interest in the permit/approval. Takings can involve broader “sticks” in ownership, but you still must show a compensable “taking,” not merely delay or disappointment.
  • Discretionary approvals: If the law says officials “may” approve based on broad factors like “public welfare,” you typically cannot claim a constitutional right to approval—because no one promised it would be granted.
  • Regulatory taking by delay: A takings claim is not a general complaint about slow government. Only highly unusual (“extraordinary”) delays that effectively and severely burden property rights may qualify.
  • Class-of-one equal protection: This is not “the government made a mistake.” It is “the government singled me out irrationally.” You usually must show close comparators—others in the same situation who were treated better—plus evidence you are a clear outlier.
  • Monell municipal liability: A city is not liable under § 1983 just because an employee did something unconstitutional. You must show the city itself—through a policy, custom, failure-to-train, or an act by a final policymaker—caused the violation.
  • Cat’s paw: In employment law, a biased subordinate can sometimes “use” a neutral decisionmaker to cause harm. This opinion signals that such imputation is a poor fit for Monell, where respondeat superior is forbidden.

5. Conclusion

Rubicon Real Estate Holdings v. City of Pontiac, Michigan is a doctrinally disciplined rejection of constitutionalizing local permitting disputes. The Sixth Circuit held that discretionary zoning/licensing systems generally do not create due process entitlements; that delay becomes a taking only when “extraordinary,” not merely costly or frustrating; that class-of-one equal protection claims require strong comparator-based proof of “stark outlier” treatment; and that municipal liability cannot be built on “cat’s paw” imputation where final policymaking authority lies elsewhere.

For future litigants, the message is practical as well as legal: where the alleged harm is bureaucratic drag in a multi-step discretionary regime, the most promising remedies are typically political, administrative, contractual, or state-law based—not federal constitutional damages under § 1983.
