Statutory Interpretation – Vehicles in the Park

The Nature of Statutes

• Congress writes statutes to set policy—so-called legislative supremacy.
  • Judges’ constitutional duty: implement congressional policy if the statute is constitutional.
  • Interpretation = uncovering “legislative intent,” i.e., what Congress sought to achieve with the chosen words.

Sources of Difficulty in Interpretation

• Language limitations
  • Words are inherently imperfect; they cannot anticipate every factual permutation.
  • Human drafters are fallible and cannot foresee the future.
  • Political compromise often forces vague or sloppy wording.
• Result: even “simple” statutes hide complex interpretive puzzles.

Teaching Illustration: “No vehicles in the park.”

• Originated in 1950s debate between H. L. A. Hart (Oxford) & Lon Fuller (Harvard).
• Apparent simplicity masks interpretive challenges.
• Immediate “core” / “easy” applications (Hart’s term):
  • Cars, trucks, motorcycles.
  • Purpose analysis supports this: safety, noise, exhaust, congestion.
• Hard cases introduced for classroom analysis:
  1. Bicycle ridden into the park → ticketed.
  2. Ambulance driven into the park for an emergency → ticketed.

Five Major Interpretive “Tools” (only first two covered in depth here)

1. Ordinary Meaning

• Supreme Court directive: always start here.
• Rationale: Congress chose these words; begin by asking how ordinary readers would understand them.
• Method:
  • Examine how the key term is used in common language.
  • Dictionaries offer empirical snapshots of usage.
• Example with “vehicle” (American Heritage definitions):
  1. “A device or structure for transporting persons or things; a conveyance.”
  2. “A self-propelled conveyance that runs on tires; a motor vehicle.”
• Ambiguity arises when multiple definitions plausibly fit—lawyers label the statute ambiguous.
  • Bicycle = fits def. 1 (broader), not def. 2 (narrower & motorized).
  • Ambulance = fits both definitions ⇒ no lexical ambiguity, yet policy concerns still surface.

2. Purpose / Policy (Teleological Approach)

• If text alone doesn’t resolve the ambiguity, ask: Which reading better serves the statute’s policy?
• Inferring policy:
  • Common sense (noise, safety, pollution) often suffices.
  • Legislative history & preambles (not discussed in depth here) can provide explicit statements.
• Application:
  • Bicycle:
  • Noise/exhaust concerns absent.
  • Collision risk exists but may be less than cars & is tied to typical recreational park use.
  • Result: many interpreters exclude bicycles from prohibition or regulate separately.
  • Ambulance:
  • Clearly a vehicle, yet banning it defeats life-saving emergency response—an absurd result.
  • Judges often craft an implicit exception (“unless the vehicle is engaged in emergency services”).
• Justifications for judicial flexibility:
  • Congress legislates in broad strokes, cannot list every exception (e.g., ambulances, police cars, sanitation trucks).
  • Courts sometimes “rewrite” to avoid absurd or counter-purpose outcomes, assuming Congress would have done so with greater foresight.

Linking Both Tools

• Textual meaning and statutory purpose form a feedback loop:
  • Text first → reveals possible meanings.
  • Purpose second → filters those meanings by alignment with legislative goals.
  • Only rarely should courts override plain meaning due to absurdity doctrine.

Practical & Philosophical Implications

• Shows tension between fidelity to enacted text vs. faithful execution of legislative policy.
• Raises debates on judicial activism vs. restraint:
  • Should judges ever deviate from clear words to achieve policy coherence?
  • Fuller (natural law leanings) vs. Hart (legal positivism) famously disagreed.
• Real-world stakes: traffic enforcement, emergency response, environmental protection, individual liberties.

Take-Away Checklist for Interpreting Any Statute

1. Identify the operative text.
2. Ask: Does ordinary meaning clearly resolve the dispute?
3. If ambiguous, articulate the competing definitions.
4. Investigate statutory purpose/policy.
5. Consider whether one reading produces an absurd or unintended result.
6. Decide which interpretation best harmonizes text & purpose—recognizing limits on judicial rewriting.

Use the bicycle vs. ambulance hypotheticals as recurring references whenever analyzing statutory interpretation problems: they crystallize how ordinary meaning, policy, and the absurdity doctrine interact.
