The separation of powers - Power to enforce the 13th, 14th, and 15th Amendments

Learning Outcomes

After reading this article, you will be able to explain Congress’s enforcement powers under the 13th, 14th, and 15th Amendments, distinguish between valid remedial and invalid substantive legislation, and identify the constitutional limits on federal authority to regulate state and private conduct. You will be able to apply these principles to MBE-style questions involving federal civil rights statutes and state sovereignty.

MBE Syllabus

For MBE, you are required to understand how the separation of powers shapes Congress’s ability to enforce civil rights through the 13th, 14th, and 15th Amendments. This includes:

  • The distinction between Congress’s enforcement powers and its general legislative powers.
  • The scope of Congress’s authority to regulate private and state conduct under each Amendment.
  • The limits on Congress’s enforcement powers, including the “congruence and proportionality” test.
  • The relationship between federal enforcement statutes and state sovereignty.

Introduction

Congress’s power to enforce the 13th, 14th, and 15th Amendments is a central feature of the separation of powers in U.S. constitutional law. These Amendments, known as the Civil War Amendments, each contain an enforcement clause granting Congress authority to pass legislation to secure the rights they guarantee. However, the scope and limits of this enforcement power differ for each Amendment and are subject to important constitutional constraints.

Key Term: Enforcement Clause The section of the 13th, 14th, or 15th Amendment that gives Congress the power to pass laws to implement the Amendment’s guarantees.

The 13th Amendment: Abolishing Slavery and Its Incidents

The 13th Amendment prohibits slavery and involuntary servitude throughout the United States. Its enforcement clause gives Congress broad power to legislate against both slavery and the “badges and incidents” of slavery, including private racial discrimination.

Key Term: Badges and Incidents of Slavery Forms of discrimination or oppression that are considered to be remnants or consequences of slavery, which Congress may address under the 13th Amendment.

  • Congress may regulate both state and private conduct under the 13th Amendment.
  • No state action is required; Congress can prohibit purely private acts of racial discrimination.

The 14th Amendment: Equal Protection and Due Process

The 14th Amendment’s enforcement clause allows Congress to pass laws to prevent or remedy violations of the Amendment’s guarantees by state governments. However, Congress’s power here is limited:

  • Congress may only regulate state action, not private conduct.
  • Congress cannot redefine or expand the substantive rights guaranteed by the 14th Amendment beyond what the Supreme Court has recognized.
  • Congress’s remedial legislation must be “congruent and proportional” to the pattern of constitutional violations by states.

Key Term: Congruence and Proportionality Test The requirement that Congress’s remedial legislation under the 14th Amendment must be closely tailored to remedy or prevent actual constitutional violations as defined by the courts.

Key Term: State Action Conduct by state or local governments (or their officials) that is required for most constitutional rights to be enforced; private conduct is generally not covered by the 14th Amendment.

The 15th Amendment: Voting Rights

The 15th Amendment prohibits states from denying or abridging the right to vote based on race or color. Congress’s enforcement power here is similar to that under the 14th Amendment:

  • Congress may pass laws to prevent racial discrimination in voting by state and local governments.
  • Congress may not regulate private conduct unrelated to state voting procedures.

Worked Example 1.1

Scenario: Congress passes a law making it a federal crime for any private business to refuse service to customers based on race.

Answer: This law is valid under the 13th Amendment, which allows Congress to prohibit private racial discrimination as a “badge or incident” of slavery. No state action is required.

Worked Example 1.2

Scenario: Congress enacts a statute requiring states to provide religious exemptions from generally applicable laws, even when the Supreme Court has held that such exemptions are not constitutionally required.

Answer: This statute is likely unconstitutional as applied to the states under the 14th Amendment. Congress cannot expand the substantive rights recognized by the Supreme Court; it may only enact remedies that are congruent and proportional to actual constitutional violations by states.

Worked Example 1.3

Scenario: Congress passes a law barring states from using literacy tests as a condition for voting in state elections.

Answer: This law is valid under the 15th Amendment’s enforcement power, as it targets state practices that could be used to deny voting rights based on race.

Exam Warning

The Supreme Court has struck down federal statutes that attempt to redefine constitutional rights or regulate private conduct under the 14th or 15th Amendments. Always check whether Congress is acting within its remedial, not substantive, authority.

Revision Tip

Remember: Only the 13th Amendment allows Congress to regulate private conduct directly. The 14th and 15th Amendments require state action.

Summary

Congress’s enforcement powers under the 13th, 14th, and 15th Amendments are a key exception to the usual limits on federal authority. The 13th Amendment allows Congress to prohibit both state and private racial discrimination. The 14th and 15th Amendments permit Congress to enact remedies for state violations of constitutional rights, but not to expand those rights or regulate private conduct. The “congruence and proportionality” test limits Congress’s remedial authority under the 14th and 15th Amendments.

Key Point Checklist

  • Congress’s remedial legislation under the 14th and 15th Amendments must be congruent and proportional to actual state violations.
  • State action is required for Congress to act under the 14th and 15th Amendments; private conduct is not covered.
