UBE Takings and State Action

Last updated: May 2, 2026

Takings and State Action questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Under the Fifth Amendment (incorporated against the states via the Fourteenth), the government may not take private property for public use without just compensation. A 'taking' includes (i) a permanent physical occupation or appropriation, (ii) a regulation that denies the owner all economically beneficial use (Lucas), or (iii) a regulation that, under the Penn Central balancing factors, goes 'too far.' Separately, the state action doctrine limits constitutional claims (other than the Thirteenth Amendment) to conduct fairly attributable to government — purely private conduct is not actionable unless the private actor performs a traditional, exclusive public function or is sufficiently entwined with the state through coercion, joint participation, or significant encouragement.

Elements breakdown

Per Se Physical Taking

Any permanent physical invasion or appropriation of private property by government — however minor — is a categorical taking requiring just compensation.

  • Government-authorized physical invasion
  • Permanent in character (or required permanent access)
  • Of private property
  • Without owner's voluntary consent

Common examples:

  • Cable boxes permanently affixed to a building (Loretto)
  • Granting third parties a permanent easement of access
  • Government appropriation of funds, liens, or specific personal property (Horne v. USDA — raisins)

Total Regulatory Taking (Lucas Rule)

A regulation that permanently deprives the owner of all economically beneficial or productive use of the land is a categorical taking unless the restriction inheres in background principles of state property or nuisance law.

  • Regulation by government entity
  • Deprives owner of 100% of economically beneficial use
  • Restriction not rooted in background nuisance/property principles
  • Owner held a cognizable property interest at the time

Common examples:

  • Coastal-zone statute barring all residential construction on a buildable lot
  • Wetlands rule eliminating every productive use of a parcel

Partial Regulatory Taking (Penn Central Balancing)

When a regulation diminishes property value but leaves some beneficial use, courts balance three factors to decide whether it has gone 'too far' and therefore effects a taking.

  • Economic impact of the regulation on the claimant
  • Extent of interference with distinct investment-backed expectations
  • Character of the government action (physical vs. regulatory; broad public program vs. targeted burden)

Common examples:

  • Landmark preservation laws restricting air rights
  • Zoning overlays limiting density on income-producing parcels

Exactions (Nollan / Dolan / Koontz)

When a permit condition demands that the owner convey property or money, the condition must satisfy heightened scrutiny tied to the project's impacts.

  • Essential nexus between condition and legitimate state interest (Nollan)
  • Rough proportionality between condition and projected impact (Dolan)
  • Applies whether condition is granted or denied, and to monetary exactions (Koontz)
  • Burden on government to justify the demand

Common examples:

  • Beachfront permit conditioned on a public-access easement
  • Building permit conditioned on dedicating a bike path

Public Use Requirement

Government may take property only for a 'public use,' which the Court reads broadly to include any rationally conceived public purpose, including economic development through transfer to private parties (Kelo).

  • Taking serves a conceivable public purpose
  • Rationally related to that purpose
  • Need not literally be 'used by the public'
  • Just compensation must still be paid

Common examples:

  • Condemnation for a comprehensive redevelopment plan
  • Slum-clearance transfers to private redevelopers (Berman)

Just Compensation

The constitutional remedy is the fair market value of the property taken at the time of the taking, measured by the owner's loss, not the government's gain.

  • Fair market value at time of taking
  • Highest and best use of the property
  • Includes severance damages where partial taking diminishes remainder
  • Sentimental or special value to owner is excluded

State Action — Public Function

A private actor's conduct is treated as state action when the actor performs a function traditionally and exclusively reserved to the government.

  • Function is traditionally governmental
  • Function is exclusively governmental (not merely 'public-serving')
  • Private actor exercises that power

Common examples:

  • Running elections / party primaries (Terry v. Adams)
  • Operating a company-owned town with municipal characteristics (Marsh)
  • Note: education, utilities, shopping malls, and private security are NOT exclusive public functions

State Action — Significant State Involvement (Entanglement)

A private party's conduct counts as state action when government is sufficiently entwined with, encourages, or jointly participates in the challenged conduct.

  • Symbiotic relationship / joint participation with the state
  • Or coercion or significant encouragement of the private conduct
  • Or pervasive entwinement of public officials in private body
  • Mere licensing, regulation, or public funding is insufficient

Common examples:

  • Private restaurant leasing space in a public parking authority (Burton)
  • Pre-judgment attachment carried out by sheriff at creditor's request (Lugar)
  • State athletic association entwined with public school officials (Brentwood Academy)

Common patterns and traps

The Loretto-vs-Penn-Central Trigger

MBE writers love to dangle a tiny physical intrusion alongside a heavy regulatory burden and tempt you to treat both the same. Loretto applies only when there is a permanent physical occupation — even one cubic foot is enough — and it is automatically compensable regardless of public benefit or minimal economic impact. Regulations that merely diminish value, even severely, fall outside Loretto and into Penn Central balancing.

A choice that says 'No taking, because the intrusion is minor and serves a public purpose' is wrong if there is any permanent physical occupation.

The Lucas Total-Wipeout Mirage

Candidates over-apply Lucas the moment a regulation looks severe. Lucas requires the owner to lose 100% of economically beneficial use; a 90% diminution is still Penn Central. Watch for facts mentioning that the owner can still farm, camp, lease for limited use, or sell — any residual economic use defeats Lucas.

A distractor saying 'categorical taking under Lucas' when the vignette mentions the owner can still use the land for limited recreational or agricultural purposes.

The State Action Bypass Trap

Constitutional claims live or die on state action. Examiners present sympathetic plaintiffs harmed by powerful private actors — a private university, an HOA, a private hospital — and dare you to apply the Constitution. Unless the actor performs a function traditionally AND exclusively governmental (very narrow — basically elections and company towns), or is entwined/coerced by the state, the constitutional claim fails at the threshold.

A choice reaching the merits ('the regulation effects a taking') when the actor is a private body and the better answer is 'no state action, so no Fifth Amendment claim.'

The Exaction Switcheroo (Nollan/Dolan/Koontz)

When a permit is conditioned on giving up property OR paying money, switch from Penn Central to heightened exactions scrutiny. The condition must have an essential nexus to a legitimate government interest and be roughly proportional to the project's impact. Koontz extended this to monetary exactions and to denials, not just grants.

A choice upholding the condition because it 'reasonably advances a public purpose' — that is rational basis, not the Nollan/Dolan standard.

Public Use Misread as Heightened Scrutiny

After Kelo, 'public use' is essentially any rationally conceivable public purpose, including economic redevelopment that transfers property to private developers. Candidates often invalidate such transfers, mistakenly applying a stricter standard. The remaining check is just compensation, not a narrow definition of 'use by the public.'

A distractor stating 'the taking is invalid because the property will be used by a private developer.'

How it works

Picture Reyes, who owns a 4-acre coastal lot. If the city installs a permanent stormwater pipe across her parcel, that's a Loretto physical taking — small, permanent, automatic compensation. If the state's coastal commission then enacts a regulation banning every form of construction or use on the parcel, you've entered Lucas territory: 100% loss of economically beneficial use is a categorical taking unless background nuisance law already barred Reyes's intended use. Anything short of total wipeout — say, a height limit that drops her parcel's value 60% — is analyzed under Penn Central, weighing economic impact, investment-backed expectations, and the character of the regulation. If instead the city offers Reyes a building permit conditioned on dedicating a public beach easement, you switch to Nollan/Dolan exactions analysis: the city must show essential nexus and rough proportionality. State action is the threshold gate for any constitutional challenge — if a private homeowners' association, not the city, imposed the same restriction, the Takings Clause does not apply at all unless that HOA is performing an exclusive public function or is entwined with the state.

Worked examples

Worked Example 1

Has the city effected a taking requiring just compensation?

  • A No, because the economic impact on Patel is negligible and the ordinance applies generally to all multi-unit buildings.
  • B No, because the ordinance reasonably advances public safety, satisfying the Penn Central balancing test.
  • C Yes, because the ordinance authorizes a permanent physical occupation of Patel's property, regardless of size or public benefit. ✓ Correct
  • D Yes, because the ordinance deprives Patel of all economically beneficial use of the rooftop under Lucas.

Why C is correct: Under Loretto v. Teleprompter Manhattan CATV Corp., a permanent physical occupation authorized by government is a per se taking, no matter how minor the economic impact or how weighty the public justification. Bolting a city-controlled antenna into Patel's roof is a permanent physical occupation, so just compensation is owed regardless of size, generality, or benefit.

Why each wrong choice fails:

  • A: Loretto is categorical: economic impact and the regulation's general applicability are irrelevant once a permanent physical occupation exists. This answer wrongly imports Penn Central balancing factors into a per se physical-taking analysis. (The Loretto-vs-Penn-Central Trigger)
  • B: Penn Central does not apply where the government authorizes a permanent physical invasion. Reasonableness and public-safety justification do not save a Loretto taking — that's the whole point of the categorical rule. (The Loretto-vs-Penn-Central Trigger)
  • D: Lucas requires loss of 100% of economically beneficial use of the parcel as a whole. Patel still has a fully functioning 12-unit building; the rooftop antenna deprives him of essentially nothing economically. The taking is physical, not a Lucas wipeout. (The Lucas Total-Wipeout Mirage)
Worked Example 2

Will Liu prevail on her categorical-taking theory?

  • A Yes, because the statute eliminated her primary investment-backed expectation of residential subdivision.
  • B Yes, because an 82% diminution in value is so severe that it must be treated as a total deprivation of economically beneficial use.
  • C No, because the statute leaves Liu with economically beneficial uses — paid recreation and timber harvesting — so Lucas does not apply. ✓ Correct
  • D No, because background principles of nuisance law independently barred Liu's intended residential use of the watershed.

Why C is correct: Lucas's categorical rule applies only when a regulation deprives the owner of ALL economically beneficial or productive use of the land. Because Liu may still operate paid recreation and harvest timber — generating real economic value — she retains beneficial use, and Lucas's categorical rule does not apply. Her claim must instead be evaluated under Penn Central balancing, where the 82% diminution and frustrated investment-backed expectations are weighed against the regulation's character.

Why each wrong choice fails:

  • A: Frustrated investment-backed expectations are a Penn Central factor, not a Lucas trigger. The categorical rule turns on whether ALL economic use has been eliminated, not on whether the owner's preferred use has been blocked. (The Lucas Total-Wipeout Mirage)
  • B: The Court has expressly rejected near-total-deprivation as a substitute for total deprivation. Even a 95% diminution is analyzed under Penn Central, not Lucas, so long as some economically beneficial use remains. (The Lucas Total-Wipeout Mirage)
  • D: While background nuisance principles are a recognized defense to a Lucas claim, the facts give no indication that residential subdivision was already a nuisance under state law. This answer reaches the right outcome via the wrong reasoning, and the cleaner basis for denial is that Lucas simply does not apply when beneficial uses remain. (Public Use Misread as Heightened Scrutiny)
Worked Example 3

What is the most likely outcome of Reyes's federal constitutional claims?

  • A Reyes will prevail on both claims because the HOA's lien-recording authority is delegated by state law, making it a state actor.
  • B Reyes will prevail on the takings claim only, because the lien is a permanent appropriation of an interest in her property.
  • C Reyes's claims will fail because the HOA is not a state actor — it does not perform a traditional and exclusive public function and is not significantly entwined with the state. ✓ Correct
  • D Reyes's claims will fail because homeowners impliedly waive constitutional rights by purchasing in a covenant-restricted community.

Why C is correct: The Constitution's individual-rights guarantees, including the First Amendment and the Takings Clause (other than the Thirteenth Amendment), apply only to state action. A private HOA enforcing recorded covenants is not performing a traditional and exclusive public function, and mere state authorization to record liens — like generic licensing or regulation — is insufficient entwinement to convert private conduct into state action. Reyes's claims fail at the threshold without reaching the merits.

Why each wrong choice fails:

  • A: The Court has repeatedly held that a state's general grant of authority — including lien-recording authority used by countless private creditors — does not by itself transform a private actor into a state actor. Significant encouragement, coercion, or joint participation in the specific challenged conduct is required. (The State Action Bypass Trap)
  • B: This answer skips the threshold state-action question and jumps to the merits of the Takings Clause. Without state action, there is no constitutional taking claim against the HOA regardless of how the lien is characterized. (The State Action Bypass Trap)
  • D: While covenant-based waiver is a real concept in some property contexts, the cleaner and constitutionally correct ground is the absence of state action. This distractor invents a doctrinal basis the Supreme Court has not adopted in this form. (The State Action Bypass Trap)

Memory aid

Takings ladder: PHYSICAL → TOTAL → PARTIAL → EXACTION (Loretto / Lucas / Penn Central / Nollan-Dolan-Koontz). State action: 'PEE' — Public function (exclusive), Entanglement, Encouragement.

Key distinction

Distinguish a Lucas total taking (100% loss of economic use → categorical) from a Penn Central partial taking (less than 100% → balancing). The categorical rule is narrow and rarely satisfied; on the MBE, if the facts mention any remaining use — agricultural, recreational, even speculative resale — apply Penn Central, not Lucas.

Summary

Government must pay just compensation when it physically appropriates property, eliminates all economic use, fails Penn Central balancing, or imposes a permit exaction lacking nexus and proportionality — and constitutional protections only attach when the challenged conduct is fairly attributable to the state.

Frequently asked questions

What is takings and state action on the UBE?

Under the Fifth Amendment (incorporated against the states via the Fourteenth), the government may not take private property for public use without just compensation. A 'taking' includes (i) a permanent physical occupation or appropriation, (ii) a regulation that denies the owner all economically beneficial use (Lucas), or (iii) a regulation that, under the Penn Central balancing factors, goes 'too far.' Separately, the state action doctrine limits constitutional claims (other than the Thirteenth Amendment) to conduct fairly attributable to government — purely private conduct is not actionable unless the private actor performs a traditional, exclusive public function or is sufficiently entwined with the state through coercion, joint participation, or significant encouragement.
