Week 1- Modes of Constitutional Interpretation
I. Introduction to Case Law & Constitutional Interpretation
A. Crash Course: Supreme Court
What is the Supreme Court?
→ The highest court in the United States, created by Article III of the Constitution.
→ It has final authority on interpreting the Constitution and resolving major federal legal disputes.
→ Sits at the top of the federal judiciary and its decisions bind all lower courts.
What does it do?
→ Reviews lower‑court decisions to determine whether they align with the Constitution.
→ Selects a very small number of cases each year (around 70–80) from thousands of petitions.
→ Issues decisions that set binding national precedent.
→ Shapes constitutional meaning through majority, concurring, and dissenting opinions.
→ Uses judicial review to evaluate the constitutionality of laws and executive actions.
Key terms/concepts:
→ Judicial Review — Power to declare laws or executive actions unconstitutional.
→ Writ of Certiorari — The formal process by which the Court agrees to hear a case.
→ Rule of Four — At least four justices must vote to grant certiorari; allows minority viewpoints among justices to bring cases forward.
→ Majority Opinion — The official decision of the Court; becomes binding precedent only when five or more justices agree on both the holding and the reasoning.
→ Holding — The legal rule or outcome of the case.
→ Rationale — The reasoning the Court uses; must have majority support to become precedent.
→ Concurring Opinion — Agrees with the outcome but not the reasoning; not binding unless it provides the narrowest grounds in a fragmented decision.
→ Dissenting Opinion — Written by justices who disagree with the majority; not binding on lower courts. Dissents can be persuasive or influential over time, but lower courts are not obligated to follow them.
→ Precedent / Stare Decisis — Courts follow prior decisions to maintain consistency and stability in the law.
→ Oral Arguments — Lawyers present their case and answer questions from the justices.
→ Amicus Curiae Briefs — “Friend of the court” briefs submitted by outside groups to influence the Court’s reasoning
Important takeaway:
→ The Supreme Court’s influence comes not just from its decisions but from which cases it chooses to hear.
→ Certiorari and the Rule of Four give the Court enormous control over the legal and constitutional issues that shape national policy.
→ A Supreme Court decision only becomes binding precedent when five or more justices agree on both the holding and the reasoning.
→ Dissents and concurrences do not create binding precedent — only majority-supported reasoning does.
→ Even though the Court hears few cases, each decision can have sweeping, long‑term effects on rights, institutions, and governance.
Connection to course readings:
→ Case Law & Constitutional Interpretation :
Shows how precedent is formed and why lower courts must follow majority holdings but not dissents.
Connects directly to how constitutional meaning evolves through selective case review.
B. Crash Course: Judicial Review
What is judicial review?
→ The power of courts — especially the Supreme Court — to review and invalidate government actions that conflict with the Constitution.
What does it allow courts to do?
→ Strike down unconstitutional laws, policies, and actions from Congress, the President, federal agencies, and state governments.
Key terms/concepts:
Judicial review
→ The authority of courts to decide whether government actions follow the Constitution.
Appellate jurisdiction
→ The power of higher courts to review decisions made by lower courts.
→ Appellate decisions are binding only on lower courts within that jurisdiction, but they also act as signals to other courts and legislatures about how judges may rule in future cases.
Supremacy Clause
→ Establishes that the Constitution and federal laws override conflicting state laws.
→ This is why Supreme Court civil‑rights decisions often strike down discriminatory state laws — federal constitutional protections supersede state action.
Congressional statutes
→ Laws passed by Congress that courts can uphold or strike down.
State actions
→ Laws or executive actions by states that courts can review for constitutionality.
→ Civil‑rights expansions frequently come from invalidating unconstitutional state laws.
Federal bureaucratic actions
→ Rules or decisions made by federal agencies that courts may invalidate.
Presidential actions
→ Executive orders or decisions by the President that courts can review.
→ Example: United States v. Nixon — the Court required President Nixon to turn over the Watergate tapes, rejecting his claim of absolute executive privilege.
Marbury v. Madison
→ The landmark case where the Supreme Court established judicial review.
Writ of mandamus
→ A court order requiring a government official to perform a duty.
Stare decisis
→ The principle of following previous judicial decisions to maintain consistency.
Precedent
→ Earlier court rulings that guide future decisions.
Implied powers
→ Powers not explicitly stated in the Constitution but understood as necessary for government functions.
Separation of powers concerns
→ Issues that arise when one branch (like the judiciary) checks or limits the actions of another branch.
Important takeaway:
→ Judicial review is not written in the Constitution — the Supreme Court claimed this power in Marbury v. Madison, and it has shaped how courts check the other branches ever since.
Connection to course readings:
→ Judicial review connects directly to this module’s focus on case law and constitutional interpretation because it shows how courts use constitutional text, precedent, and interpretive methods to evaluate government actions. Judicial review is the mechanism through which case law develops, and it demonstrates how judges interpret the Constitution to resolve conflicts between federal authority and state action — especially in civil‑rights cases.
II. Modes of Constitutional Interpretation — 25 pages
(Add a subsection for each major heading/subheading in the reading.)
[Textualism]
What is it?
→A mode of interpretation that focuses on the plain meaning of the constitutional text as understood at the time of ratification.
What does it focus on?
→The words themselves, their ordinary meaning, and the context in which they appear.
→ Avoids looking at the intent of framers or ratifiers.
Basic principle/rule:
→The Constitution has an objective, fixed meaning rooted in its text.
→ Judges should not revise or refine constitutional language.
Why does it matter?
→Provides simplicity, transparency, and predictability.
→ Limits judicial discretion and prevents judges from inserting personal policy views.
Example/case:
→Trop v. Dulles — Court began with text of “cruel and unusual punishment” before turning to other methods.
→ Dennis v. United States — Justice Black’s dissent: First Amendment’s text (“no law”) absolutely forbids speech restrictions.
→ Griswold v. Connecticut — Justice Black’s dissent criticized the majority for finding rights not in the text.
Criticism or limitation:
→Broad or vague constitutional language can produce multiple meanings.
→ Judges may still disagree on what the “plain meaning” is. → Critics argue textualism ignores values, moral reasoning, and evolving societal needs.
How is it different from other approaches?
→ Unlike originalism, textualism does not seek framers’ intent or public meaning beyond the text.
→ Unlike pragmatism, textualism does not weigh consequences.
→ Unlike moral reasoning, textualism does not consider underlying ideals.
Key takeaway:
→Textualism anchors interpretation in the words of the Constitution, resisting judicial innovation or policy-driven interpretation.
Question I should be able to answer:
→ Why do textualists believe the Constitution should be interpreted strictly according to its words? It prevents judges from making rulings based on their personal beliefs; it promotes democratic values by adhering to the words of the Constitution adopted by the people, rather than what individual justices believe.
→ What do opponents of textualism argue? Different meanings of the Constitution can be made based on the judges’ background, so that doesn’t ensure they will interpret it the same, and that interpretations should be based on moral reasoning, practical consequences, structural relationships, or other considerations
[Originalism]
What is it?
→ A mode of interpretation that seeks the public meaning of constitutional text at the time of the Founding.
What does it focus on?
→ How ordinary citizens or a reasonable person in the Founding era understood the text.
→ Historical sources: dictionaries, debates, common law, early state constitutions.
Basic principle/rule:
→ The Constitution has a fixed meaning that does not change unless formally amended.
Why does it matter?
→ Limits judicial discretion.
→ Grounds interpretation in democratic legitimacy — the meaning chosen by the people who ratified the Constitution.
Example/case:
→ District of Columbia v. Heller — Court used Founding-era dictionaries and historical sources to determine the Second Amendment’s original public meaning.
→ Myers v. United States — Court relied on Constitutional Convention debates and early congressional practice to determine removal power.
Criticism or limitation:
→ Historical sources can be conflicting, incomplete, or ambiguous.
→ Judges may “select” historical evidence that aligns with their views.
→ Original meaning may not address modern issues (e.g., digital privacy, technology).
→ May fail to protect minority rights given historical inequalities.
How is it different from other approaches?
→Unlike textualism, originalism looks beyond the text to historical meaning.
→ Unlike precedent, originalism may reject case law that conflicts with original meaning.
→ Unlike pragmatism, originalism does not weigh consequences.
Key takeaway:
→ Original meaning seeks to preserve the Constitution’s fixed historical meaning, preventing judicial reinterpretation over time
Question I should be able to answer:
→ What sources do originalists use to determine the Constitution’s meaning?
One should look to the original intent of the people who drafted, proposed, adopted, or ratified the Constitution to determine what those people wanted to convey through the text. According to this view, original intent may be found in sources outside of the text, such as debates in the Constitutional Convention or the Federalist Papers. The approach limits judicial discretion, preventing judges from deciding cases in accordance with their own political views.
→ What do opponents of originalism argue?
Lack of consensus on the original meaning of the Constitution; judges may simply choose the original view that supports their political beliefs. Opponents also argue that originalism requires judges to act as historians—a role for which they may not be well suited—as opposed to as decisionmakers.
[Judicial Precedent]
What is it?
→ Using prior Supreme Court decisions as a source of constitutional meaning.
What does it focus on?
→ Principles, rules, and standards established in earlier cases.
→ Stare decisis — following precedent for consistency and stability.
Basic principle/rule:
→ Courts should follow earlier decisions unless they are clearly wrong or unworkable.
Why does it matter?
→ Provides predictability, neutrality, and stability.
→ Helps constitutional norms evolve gradually.
→ Signals how courts may rule in future cases.
Example/case:
→ Planned Parenthood v. Casey — plurality reaffirmed Roe v. Wade based on precedent.
→ Dickerson v. United States — Court refused to overrule Miranda because it was deeply embedded in national practice.
→ Arizona State Legislature v. AIRC — Court relied on early 20th‑century precedents to interpret “Legislature.”
Criticism or limitation:
→ Some precedents may be wrongly decided (e.g., Plessy v. Ferguson) especially when society no longer agrees with the moral or constitutional principles behind a decision.
→ Judges can interpret precedents broadly or narrowly to fit their views.
→ Precedent may conflict with original meaning.
How is it different from other approaches?
→ Unlike textualism or originalism, precedent relies on judicial decisions, not text or history.
→ Unlike pragmatism, precedent does not weigh consequences — it follows prior rulings.
Key takeaway:
→ Precedent is the most commonly used interpretive method and shapes constitutional meaning through accumulated case law.
Question I should be able to answer:
→ Why does the Supreme Court sometimes uphold precedent even when some Justices believe it was wrongly decided?
Even if some Justices think a case was wrongly decided, they may uphold it to preserve consistency in the law, avoid disrupting settled expectations, and prevent the appearance that constitutional meaning changes simply because the Court’s membership changes. Additionally, some Justices believe that precedent should stand unless it is unworkable or deeply incompatible with constitutional principles, even if they personally disagree with the original ruling.
[Pragmatism]
What is it?
→ A method of constitutional interpretation where judges choose the meaning that produces the best practical, real‑world consequences.
What does it focus on?
→ Future outcomes, policy consequences, and institutional functioning rather than strict text or historical meaning.
Basic principle/rule:
→ Interpret the Constitution in the way that works best in practice and avoids harmful or unworkable results.
Why does it matter?
→ Helps the Court address modern problems the Constitution never anticipated, ensures government can function effectively, and prevents rigid interpretations from causing real‑world harm.
Example/case:
→United States v. Leon (1984) — The Court created the good‑faith exception because excluding evidence obtained with a defective warrant would impose high societal costs and offer minimal deterrence benefits.
→ United States v. Comstock (2010) — Upheld federal civil commitment as a practical extension of Congress’s existing powers that supports effective institutional operation.
Criticism or limitation:
→ Gives judges broad discretion, risks weakening constitutional constraints, can appear unpredictable, and may allow personal or political preferences to influence “consequences.”
How is it different from other approaches?
→Textualism: Follows the text even if consequences are bad; pragmatism prioritizes outcomes.
→ Original Meaning: Bound by historical meaning; pragmatism adapts to modern realities.
→ Precedent: Prior decisions matter less if consequences justify change.
→ Moral Reasoning: Focuses on ethical ideals; pragmatism focuses on functionality and results.
Key takeaway:
→Pragmatism is consequence‑based interpretation: choose the constitutional meaning that produces the most workable, beneficial, and least harmful real‑world outcome.
Question I should be able to answer:
→How does the Supreme Court use practical consequences to justify its interpretation of the Constitution?
The Supreme Court uses practical consequences by weighing the likely real‑world effects of different constitutional interpretations and choosing the one that leads to the best functional outcome for society or government.
[Moral Reasoning]
What is it?
→ A mode of constitutional interpretation that treats broad constitutional terms as containing embedded moral concepts or ideals.
What does it focus on?
→ The ethical values, normative principles, and ideas of justice underlying clauses like “due process” and “equal protection.”
Basic principle/rule:
→ Judges should interpret constitutional language by identifying the moral concepts behind it and applying those concepts to modern circumstances.
Why does it matter?
→ Helps courts give meaning to abstract constitutional terms that cannot be resolved by text or history alone and allows doctrine to reflect evolving moral understandings.
Example/case:
→ Lawrence v. Texas (2003) — The Court struck down sodomy laws because they violated liberty and dignity, moral concepts embedded in the Due Process Clause. → Bolling v. Sharpe (1954) — The Court held that racial segregation in D.C. public schools violated the Fifth Amendment’s Due Process Clause, reasoning that the clause embodies principles of fairness and equality. Because the Fifth Amendment does not contain an Equal Protection Clause, the Court used moral reasoning to conclude that segregation was so unjust and arbitrary that it violated the Constitution’s underlying moral commitments.
Criticism or limitation:
→ Seen as too subjective, allowing judges to rely on personal values; may drift away from text or historical meaning.
How is it different from other approaches?
→Textualism: Focuses on words; moral reasoning focuses on values.
→ Original Meaning: Anchored in historical understanding; moral reasoning adapts to modern moral principles.
→ Pragmatism: Focuses on consequences; moral reasoning focuses on ethical ideals.
→ Precedent: Relies on past decisions; moral reasoning relies on underlying moral concepts.
Key takeaway:
→Moral reasoning interprets the Constitution by identifying the ethical principles embedded in broad constitutional language and applying them to contemporary issues.
Question I should be able to answer:
→ How does the Supreme Court use moral reasoning to interpret broad constitutional terms?
The Supreme Court uses moral reasoning by interpreting broad constitutional terms through the underlying moral principles and ideals they embody.
[National Idenitity/Constitutional Ethos]
What is it?
→ A mode of constitutional interpretation where judges rely on the distinct character, traditions, and values of the American national identity to elaborate the Constitution’s meaning.
What does it focus on?
→ The nation’s shared values, historical traditions, and core ideals that define what it means to be American.
→ Used especially when the Constitution contains broad or value‑laden terms (words that already contain values, ideals, or principles inside them like “liberty”).
Basic principle/rule:
→ Interpret ambiguous constitutional language in light of enduring American ideals such as liberty, democracy, family, autonomy, and freedom of thought.
Why does it matter?
→Helps the Court interpret provisions where text and history alone do not resolve the issue.
→ Allows constitutional meaning to reflect the nation’s identity and foundational values.
Example/case:
→Moore v. City of East Cleveland (1977) — The Court struck down a housing ordinance because it interfered with traditional American family structure, a core part of national identity.
→ West Virginia State Board of Education v. Barnette (1943) — The Court held that students cannot be forced to salute the flag because freedom of thought and expression are central American values.
Criticism or limitation:
→National identity can be vague and defined differently by different judges.
→ Risks allowing judges to rely on personal beliefs about what America “stands for.”
→ Can drift away from text or historical meaning.
How is it different from other approaches?
→Textualism: Focuses on words; national ethos focuses on values and traditions.
→ Original Meaning: Anchored in Founding‑era understanding; national ethos draws on evolving national identity.
→ Moral Reasoning: Uses moral principles; national ethos uses collective American values.
→ Pragmatism: Focuses on consequences; national ethos focuses on national character.
Key takeaway:
→ National Identity interprets the Constitution through the shared values and traditions that define the American nation, especially when the text is broad or value‑laden.
Question I should be able to answer:
→ How does the Supreme Court use national identity to interpret constitutional provisions when the text is ambiguous?
The Supreme Court uses national identity by interpreting constitutional provisions in light of the core values, traditions, and principles that define the American nation.
[Structualism]
What is it?
→ Structuralism interprets the Constitution by examining the relationships, design, and architecture of government created by the document. → Meaning is inferred from how the Constitution structures power among branches and between the federal government and the states.
What does it focus on?
→The Constitution’s overall design, including:
Separation of powers
Federalism
Checks and balances
Institutional relationships
→ Structuralism asks: How does this provision fit into the Constitution’s broader system?
Basic principle/rule:
→ Interpret constitutional provisions in a way that preserves the structural balance the Constitution establishes — ensuring no branch or level of government undermines another.
Why does it matter?
→Many constitutional questions are not answered by text alone, so the Court uses structural reasoning to:
Protect federal supremacy
Maintain separation of powers
Prevent state interference with federal authority
Ensure Congress follows constitutionally required procedures
Preserve the Constitution’s functional design
Example/case:
1. McCulloch v. Maryland (1819)
→ Maryland could not tax the national bank because doing so would undermine the structural supremacy of the federal government.
→ Structural reasoning: The Constitution creates a federal system where states cannot interfere with federal instruments.
2. Immigration and Naturalization Service v. Chadha (1983)
→ The Court struck down the legislative veto because it violated the structural requirements of bicameralism and presentment.
→ Structural reasoning: Congress cannot bypass the Constitution’s required lawmaking process.
3. U.S. Term Limits, Inc. v. Thornton (1995)
→ The Court held that states cannot impose additional qualifications for members of Congress because doing so violates the structural relationship between state and federal authority.
→ Structural reasoning: The Constitution’s design gives the national government control over congressional qualifications, not the states.
Criticism or limitation:
→Structural reasoning can be indeterminate — judges may infer different structural principles. → Critics argue it risks giving judges too much discretion to “read between the lines.” → It may drift away from the Constitution’s text or historical meaning.
How is it different from other approaches?
→Textualism: Looks at words; structuralism looks at relationships.
→ Original Meaning: Looks at historical understanding; structuralism looks at constitutional design.
→ Pragmatism: Focuses on consequences; structuralism focuses on preserving institutional balance.
→ Moral Reasoning: Uses values; structuralism uses architecture of government.
Key takeaway:
→ Structuralism interprets the Constitution by examining the relationships and design of government institutions, ensuring each branch and level of government stays within its proper constitutional role.
Question I should be able to answer:
→How does the Supreme Court use structural reasoning to interpret the Constitution?
The Supreme Court uses structural reasoning by inferring constitutional meaning from the relationships and design of government established by the Constitution, ensuring that separation of powers and federalism principles are preserved.
[Formalism]
What is it?
→ Formalism interprets separation‑of‑powers questions by strictly adhering to the structural divisions the Constitution establishes among the branches.
→ It assumes that close obedience to these structural rules is necessary to preserve liberty.
What does it focus on?
→ The explicit structural allocations of power in the Constitution.
→ The idea that each branch must stay within its constitutionally assigned sphere.
→ Rejects flexible balancing or historical practice as interpretive tools.
Basic principle/rule:
→ Follow the Constitution’s “single, finely wrought, and exhaustively considered” procedures and divisions of power exactly as written.
→ Do not adjust or relax structural boundaries based on convenience or historical practice.
Example/case:
→ INS v. Chadha (1983)
The Court struck down the one‑House legislative veto because it violated the structural requirements of bicameralism and presentment.
The Court emphasized strict adherence to Article I’s lawmaking process, stating that the Framers required a single, carefully designed procedure for exercising legislative power.
This is classic formalism: no balancing tests, no reliance on post‑ratification practice — just strict structural obedience.
Criticism or limitation:
→ Can be rigid and may ignore practical realities.
→ May prevent branches from adapting to modern governance needs.
→ Rejects useful historical practices that have become part of constitutional functioning.
Key takeaway:
→ Formalism = strict separation of powers.
→ Courts must follow the Constitution’s structural rules exactly as written to protect liberty.
[Functionalism]
What is it?
→ Functionalism interprets separation‑of‑powers questions using a flexible, pragmatic approach, focusing on whether a governmental arrangement disrupts the core functions of a branch.
What does it focus on?
→ The practical consequences of allocating power.
→ Whether overlapping powers upset the equilibrium the Framers intended.
→ Allows some blending of powers if it does not impair a branch’s essential role.
Basic principle/rule:
→ Ask whether the challenged action impermissibly interferes with a branch’s ability to perform its constitutional function.
→ If not, the arrangement may be constitutional even if it blurs structural lines.
Example/case
1. Zivotofsky v. Kerry (2015)
→ The Court held that the President has the exclusive power to recognize foreign sovereigns.
→ Congress cannot force the State Department to contradict the President’s recognition policy.
→ The Court reasoned that the nation must have a single, unified recognition policy, and conflicting congressional statements would cause confusion.
→ This is functionalism: the Court considered practical consequences and institutional functionality.
2. Morrison v. Olson (1988)
→ The Court upheld the independent counsel provisions of the Ethics in Government Act.
→ The independent counsel could only be removed for good cause, giving them significant independence.
→ The Court held this did not impermissibly interfere with the President’s Article II duty to ensure faithful execution of the laws.
→ Functionalist reasoning:
The independent counsel’s limited jurisdiction meant the arrangement did not destroy the President’s core executive function.
→ Justice Scalia dissented using formalism, arguing the Act violated strict separation of powers.
Criticism or limitation:
→ Can be too flexible, allowing branches to accumulate power.
→ Risks weakening structural protections by focusing too much on consequences.
→ May justify arrangements that drift from the Constitution’s original design.
Key takeaway:
→ Functionalism = flexible separation of powers.
→ Courts evaluate whether an arrangement actually harms a branch’s core function, not whether it strictly follows structural boundaries.
Question I should be able to answer:
How does the Supreme Court distinguish between formalism and functionalism in separation‑of‑powers cases?
→ The Supreme Court distinguishes formalism and functionalism by either strictly enforcing the Constitution’s structural divisions (formalism) or evaluating whether an overlap of powers disrupts a branch’s core functions (functionalism).
[Historical Practices]
What is it?
→Historical Practices is a mode of constitutional interpretation where courts look to long‑established practices of the political branches to help determine the Constitution’s meaning. → These practices act as a type of non‑judicial precedent.
What does it focus on?
→How Congress, the President, and other institutions have actually behaved over time.
→ Whether a practice is deeply rooted, long‑standing, and consistent.
→ Used especially when the Constitution’s text is ambiguous.
Basic principle/rule:
→If a governmental practice has been followed for a long time, it may help clarify what the Constitution allows or forbids.
→ Tradition can “give meaning to the words of a text or supply them.”
Why does it matter?
→Helps resolve separation‑of‑powers disputes.
→ Provides stability, predictability, and reliance.
→ Preserves long‑standing compromises between branches.
Example/case:
1. NLRB v. Noel Canning (2014)
→ The Court held the President cannot make recess appointments during recesses shorter than 10 days.
→ Why? Because there was no historical tradition supporting such short recess appointments.
2. Zivotofsky v. Kerry (2015)
→ The Court held the President has the exclusive power to recognize foreign governments.
→ The Court relied partly on the long‑standing historical practice of Presidents recognizing foreign sovereigns without Congress.
3. Marsh v. Chambers (1983)
→ The Court upheld Nebraska’s practice of opening legislative sessions with a prayer.
→ Why? Because legislative prayer is deeply embedded in American history and tradition.
Criticism or limitation:
→Hard to determine what the “correct” historical practice is. → Practices may conflict with the Constitution’s original meaning.
→ Risk of legitimizing harmful traditions (e.g., slavery, segregation).
→ Judges may cherry‑pick (“law office history”).
→ Could prevent innovation by political branches.
How is it different from other approaches?
→Original Meaning: Looks at Founding‑era intent; historical practices look at post‑Founding behavior.
→ Judicial Precedent: Uses court decisions; historical practices use political branch behavior.
→ National Ethos: Focuses on values; historical practices focus on tradition.
→ Formalism: Rejects historical practice; functionalism embraces it.
Key takeaway:
→ Historical Practices interprets the Constitution by looking at long‑standing governmental traditions, especially when the text is unclear, but it is controversial because tradition can be ambiguous or harmful.
Question I should be able to answer:
→How does the Supreme Court use historical practices to interpret the Constitution?
The Supreme Court uses historical practices by relying on long‑established governmental traditions to clarify constitutional meaning when the text is ambiguous, treating consistent past practice as evidence of how the Constitution has been understood and applied.
