Argument Structure (hlr-argument-structure)

A flagship legal article does three things in order: maps the doctrine, diagnoses the problem with a theory or principle, and prescribes what should change. This doctrine → theory → prescription arc is the spine readers and student editors expect. This skill organizes the body so each Part does one job and the prescription is earned by what precedes it.

When to trigger

• The thesis is set but the body sprawls or repeats itself
• Readers lose the thread between the doctrinal Part and the argument
• The prescription appears without the diagnosis that should justify it
• You need to decide Part order and what each Part is responsible for

The doctrine → theory → prescription arc

Construction rules

1. Each Part earns the next. The prescription must follow from the diagnosis, which must follow from the doctrinal map. If you could move a Part without loss, the logic is loose.
2. State the law fairly before you attack it. Student editors and generalist readers distrust pieces that caricature current doctrine. The strongest version of the status quo makes your critique credible.
3. Make the theory do work. A normative principle is not décor — it must generate the prescription and resolve the hard cases the doctrine cannot.
4. Pressure-test on the hard case. Apply your prescription to the fact pattern that most threatens it; if it survives, the piece is strong; if it doesn't, narrow the claim (loop hlr-thesis-and-contribution).
5. Adjudicate the single strongest objection, not a row of weak ones. Name it, take it seriously, and show why the thesis holds (or where it must be qualified).

Engaging the literature inside the argument

Engage prior scholarship where it bears on the move, not in a front-loaded lit-review dump. When you diagnose, cite the works that framed the problem; when you prescribe, distinguish the nearest rival proposals (the neighbors found in hlr-preemption-check). Footnotes carry most of this engagement.

Checklist

• Body follows doctrine → theory → prescription, each Part with one job
• The status quo is stated in its strongest form before critique
• The theory generates the prescription (not bolted on)
• The prescription is tested on the hardest case
• The single strongest objection is named and adjudicated
• Scope conditions stated — where the claim does and does not reach
• Literature engaged at the point of the move, mostly via footnotes

Anti-patterns

• A descriptive Part I that never becomes an argument (the "survey then opine" structure)
• Prescription with no diagnosis — "courts should do X" without showing why the current rule fails
• Strawmanning the doctrine so the critique lands on a position no one holds
• A wall of weak objections instead of the one that actually threatens the thesis
• Front-loaded literature review disconnected from the argument's moves

Output format

【Arc】Part I doctrine → Part II theory/diagnosis → Part III prescription → Part IV objections/scope
【Each Part's job】one line each
【Hardest case】the fact pattern that tests the prescription
【Strongest objection】and how it is adjudicated
【Scope】where the claim reaches and where it stops
【Next】hlr-sources-and-bluebook → hlr-footnotes-and-cite-check
