Con Law: Privileges and Immunities clause

Overview

The Privileges and Immunities Clause limits a state’s ability to discriminate against out-of-state citizens with respect to fundamental economic and civil rights. On the UBE, this doctrine is tested primarily through state laws that treat nonresidents less favorably than residents, especially in employment, licensing, or commercial activity.

Privileges and Immunities questions focus on whether a state has improperly burdened the ability of nonresidents to earn a livelihood, engage in commercial activity, or access basic legal protections. The analysis is narrower than Dormant Commerce Clause doctrine and applies only to individual citizens, not corporations.

Key themes tested on the UBE include:

(1) Protection of Fundamental Rights
The Clause protects rights that are fundamental to national unity, particularly economic rights.

(2) Discrimination Against Nonresidents
The doctrine applies only when a state discriminates against citizens of other states.

(3) Substantial Justification Test
Discriminatory laws may survive only if the state shows a substantial reason for the discrimination and a close relationship between the discrimination and the state’s objectives.

(4) Distinction from Dormant Commerce Clause
Privileges and Immunities protects individuals, while Dormant Commerce Clause protects interstate commerce more broadly, including corporations.

(5) Limited Scope
The Clause does not protect all rights and does not apply to every form of state residency-based distinction.

Core Rules

I. SOURCE OF THE RIGHT

Privileges and Immunities Clause (Art. IV, § 2)
“The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States.”

II. WHO IS PROTECTED

Rule:
The Clause protects individual citizens, not corporations or aliens.

Implication:

  • Corporations must rely on Dormant Commerce Clause

  • Non-citizens are not protected by this clause

III. WHO IS RESTRICTED

Rule:
The Clause restricts state governments, not federal action.

IV. THRESHOLD REQUIREMENT

Rule:
The Clause applies only when a state discriminates against nonresidents in favor of its own citizens.

If no differential treatment exists → the Clause does not apply.

V. FUNDAMENTAL RIGHTS PROTECTED

The Clause protects rights that are fundamental to interstate harmony, including:

  • Pursuing a common calling or profession

  • Employment and livelihood

  • Ownership and transfer of property

  • Access to courts

  • Basic commercial activities

VI. RIGHTS NOT PROTECTED

The Clause does not protect:

  • Recreational activities (e.g., hunting, fishing licenses)

  • Purely political rights (e.g., voting, holding public office)

  • State-provided benefits reserved for residents

VII. STANDARD OF REVIEW

Rule:
A state law discriminating against nonresidents is invalid unless the state shows:

  1. A substantial reason for the discrimination, and

  2. A close relationship between the discrimination and the state’s objective.

This is more demanding than rational basis but less strict than strict scrutiny.

VIII. SUBSTANTIAL JUSTIFICATION REQUIREMENT

Rule:
The state must show nonresidents are a peculiar source of the problem the law addresses.

Generalized economic protectionism is insufficient.

IX. RELATIONSHIP TO STATE INTEREST

Rule:
The discriminatory means must be closely related to the state’s objective.

Overinclusive or underinclusive discrimination is suspect.

X. RELATIONSHIP TO OTHER DOCTRINES

Dormant Commerce Clause

  • Applies to corporations and goods

  • Broader scope than P&I

Equal Protection Clause

  • Applies to all persons

  • Different analytical framework

Tests and standards

I. THRESHOLD APPLICABILITY TEST

Test:
Does the state law treat nonresidents differently from residents?

  • If no discrimination → Privileges & Immunities Clause does not apply

  • If yes → proceed to fundamental rights analysis

II. PROTECTED CLASS TEST

Test:
Is the claimant an individual citizen of another state?

  • Only individual U.S. citizens are protected

  • Corporations and aliens are not protected

If the claimant is not a protected person → the claim fails.

III. FUNDAMENTAL RIGHT TEST

Test:
Does the law burden a right that is fundamental to interstate harmony?

Fundamental rights commonly tested on the UBE include:

  • Pursuing a common calling or profession

  • Employment and earning a livelihood

  • Commercial and economic activities

  • Ownership, use, and transfer of property

  • Access to courts and legal processes

If the right is not fundamental → the Clause does not apply.

IV. SUBSTANTIAL JUSTIFICATION TEST (CORE STANDARD)

If a state discriminates against nonresidents with respect to a fundamental right, the law is invalid unless the state proves:

  1. A substantial reason for the discrimination, and

  2. A close relationship between the discrimination and the state’s objective

This burden rests on the state, not the challenger.

V. SUBSTANTIAL REASON ANALYSIS

Test:
Are nonresidents a peculiar source of the problem the state seeks to address?

Valid considerations may include:

  • Demonstrable differences between residents and nonresidents

  • Evidence that nonresidents uniquely contribute to the harm

Invalid justifications:

  • Economic protectionism

  • Preference for residents simply because they are residents

VI. CLOSE RELATIONSHIP (FIT) ANALYSIS

Test:
Is the discriminatory means closely tailored to solving the identified problem?

Key considerations:

  • Overinclusive laws are suspect

  • Underinclusive laws undermine justification

  • Less discriminatory alternatives weaken the state’s case

The state does not need the least restrictive means, but must show strong fit.

VII. BURDEN-SHIFTING SUMMARY

  • Challenger must show:

    • Nonresident discrimination

    • Burden on a fundamental right

  • State must then show:

    • Substantial reason

    • Close relationship

Failure at either stage invalidates the law.

VIII. COMMON COMPARATIVE ANALYSIS (EXAM MOVE)

Dormant Commerce Clause

  • Protects interstate commerce and corporations

  • Uses strict scrutiny or Pike balancing

Privileges & Immunities Clause

  • Protects individual citizens only

  • Uses substantial justification test

On the UBE, mention both doctrines when facts support them.

IX. STANDARD OF REVIEW SUMMARY

  • More demanding than rational basis

  • Less demanding than strict scrutiny

  • Heavy burden on the state once triggered

Defenses and burdens

I. GENERAL BURDEN FRAMEWORK

Challenger’s Initial Burden
The challenger must show:

  • The state discriminates against nonresidents, and

  • The discrimination burdens a fundamental right protected by the Clause.

If either element is missing, the claim fails.

II. STATE’S BURDEN (SUBSTANTIAL JUSTIFICATION)

Once the challenger meets the threshold, the burden shifts to the state.

State Must Prove:

  1. A substantial reason for the discrimination, and

  2. A close relationship between the discrimination and the state’s objective.

This is a demanding burden.

III. COMMON STATE DEFENSES

Peculiar Source Defense
The state argues that nonresidents are a unique or primary source of the problem the law addresses.

Health and Safety Defense
The state asserts that the discrimination protects public health, safety, or welfare.

Administrative Feasibility Defense
The state argues that differential treatment is necessary to manage limited resources or ensure effective enforcement.

IV. LIMITS ON STATE DEFENSES

Economic Protectionism Is Invalid
Favoring residents simply to protect local economic interests is not a substantial reason.

Speculative Justifications Are Insufficient
The state must offer evidence, not generalized assumptions.

V. CHALLENGER’S COUNTERARGUMENTS

No Substantial Reason
Nonresidents are not a peculiar source of the problem.

Poor Fit
The discrimination is overinclusive or underinclusive.

Less Discriminatory Alternatives
The state could achieve its goals through neutral or less discriminatory means.

VI. DEFENSES BASED ON SCOPE LIMITATIONS

Non-Fundamental Right Defense
The state may argue the burdened activity is not a fundamental right.

Protected Class Defense
The state may argue the claimant is not an individual citizen (e.g., a corporation).

VII. BURDEN ALLOCATION SUMMARY

  • Challenger: discrimination + fundamental right

  • State: substantial reason + close relationship

Failure by the state results in invalidation.

Exceptions and limitations

I. NONRESIDENT DISCRIMINATION REQUIREMENT

Rule:
The Clause applies only when a state discriminates against citizens of other states.

Limitation:
If residents and nonresidents are treated the same, the Clause does not apply.

II. INDIVIDUAL CITIZENS ONLY

Rule:
Only individual U.S. citizens are protected.

Limitation:

  • Corporations are not protected

  • Aliens are not protected
    Corporations must rely on the Dormant Commerce Clause instead.

III. FUNDAMENTAL RIGHTS LIMITATION

Rule:
The Clause protects only rights fundamental to interstate harmony.

Limitation:
The Clause does not apply to:

  • Recreational activities (e.g., hunting or fishing licenses)

  • Nonessential benefits

  • Purely local privileges

If the right is not fundamental, the analysis ends.

IV. POLITICAL AND GOVERNMENTAL RIGHTS EXCEPTION

Rule:
States may reserve political and governmental rights to residents.

Examples:

  • Voting

  • Holding public office

  • Serving on juries

These rights fall outside Privileges & Immunities protection.

V. STATE-PROVIDED BENEFITS LIMITATION

Rule:
States may restrict access to certain state-funded benefits to residents.

Examples:

  • Tuition subsidies

  • Welfare benefits

  • Certain licensing preferences tied to state investment

Such benefits are not considered fundamental rights of national citizenship.

VI. SUBSTANTIAL JUSTIFICATION LIMITATION

Rule:
Even when a fundamental right is implicated, discrimination may survive if the state satisfies the substantial justification test.

Limitation:
This exception is narrow and requires:

  • Evidence that nonresidents are a peculiar source of the problem, and

  • A close relationship between the discrimination and the state’s goal

VII. NO LEAST-RESTRICTIVE-MEANS REQUIREMENT

Rule:
States need not adopt the least restrictive alternative.

Limitation:
However, poor fit or obvious nondiscriminatory alternatives weaken the state’s justification.

VIII. RELATIONSHIP TO OTHER CONSTITUTIONAL DOCTRINES

Dormant Commerce Clause

  • Broader scope

  • Applies to corporations and goods

Equal Protection Clause

  • Applies to all persons

  • Different levels of scrutiny

The existence of these doctrines limits when Privileges & Immunities analysis is appropriate.

Key Cases

Corfield v. Coryell (1823)
Early foundational case defining “privileges and immunities” as rights fundamental to national unity, including the pursuit of a common calling.

Supreme Court of New Hampshire v. Piper (1985)
Invalidated a state rule limiting bar admission to residents. Illustrates that the right to pursue a profession is a fundamental right protected by the Clause.

United Building & Construction Trades Council v. Mayor of Camden (1984)
Held that a municipal ordinance favoring city residents could violate the Privileges & Immunities Clause. Confirms that the Clause applies to local as well as state laws.

Policy Notes

  • Promoting National Unity
    The Clause ensures that states do not Balkanize the nation by economically isolating their citizens from one another.

  • Protecting the Right to Earn a Living
    The core concern of the doctrine is safeguarding access to employment and commercial opportunity across state lines.

  • Limiting Economic Protectionism
    States may not favor residents simply to give them an economic advantage.

  • Individual-Centered Protection
    Unlike the Dormant Commerce Clause, Privileges & Immunities protects individual citizens, not corporations.

  • Balancing State Autonomy and Fairness
    The substantial justification test allows states to address real problems while preventing unjustified discrimination.

  • Evidence Matters
    States must support discrimination with concrete evidence, not speculation or generalized assumptions.

  • Distinct but Complementary Doctrine
    Privileges & Immunities often appears alongside Dormant Commerce Clause analysis but applies a narrower, person-focused inquiry.

Common Exam Traps

  1. Forgetting the clause protects only nonresidents
    The Privileges & Immunities Clause applies only when a state discriminates against citizens of other states.

  2. Applying the clause to corporations
    Corporations are not protected by Privileges & Immunities and must rely on the Dormant Commerce Clause instead.

  3. Ignoring the fundamental rights requirement
    The Clause protects only rights fundamental to interstate harmony, not all residency-based distinctions.

  4. Assuming recreational activities are protected
    Activities like hunting or fishing are not fundamental rights under the Clause.

  5. Treating economic protectionism as a valid justification
    Favoring residents simply to protect local economic interests is never a substantial reason.

  6. Failing to identify the substantial justification test
    Discriminatory laws must satisfy both a substantial reason and a close relationship to the state’s objective.

  7. Misallocating the burden of proof
    Once discrimination and a fundamental right are shown, the burden shifts to the state.

  8. Confusing Privileges & Immunities with Equal Protection
    These doctrines protect different interests and apply different standards of review.

  9. Overlooking local laws
    Municipal ordinances are subject to Privileges & Immunities just like state statutes.

  10. Skipping the “peculiar source of the problem” analysis
    The state must show nonresidents are a unique cause of the harm addressed.

  11. Assuming any public interest justification is sufficient
    The state must present evidence, not generalized assertions.

  12. Ignoring less discriminatory alternatives
    The existence of reasonable nondiscriminatory means undermines the state’s defense.

  13. Failing to mention Dormant Commerce Clause when applicable
    Many fact patterns support analysis under both doctrines.
