# Legal syllogism - make the reasoning explicit
## Philosophy
**A flawed opinion rarely fails at the conclusion - it fails at the premise nobody stated.** Legal
reasoning is a syllogism: the rule (major premise), the facts (minor premise), the application, and
the conclusion. When a step is left unsaid - "because it's obvious" - that is where the gap hides,
and that is where the other side, or the court, will strike. This skill forces each step to be
stated and marks what is settled and what is contested.
It **structures** the reasoning; it does not decide the case. Judgement and the decision stay with
the lawyer.
## Method (subsumption / IRAC)
1. **Major premise (rule + interpretation)** - identify the governing rule, then its reading: how
each element of the rule is construed (text, structure, purpose). Note where authority or
commentary splits.
2. **Minor premise (material facts)** - list the facts that matter to the rule's elements. Separate
undisputed facts from contested ones, and facts from characterisations.
3. **Application (subsumption)** - for each element of the rule, show which fact satisfies it (or
does not). This is the real work: matching fact to element.
4. **Conclusion** - the legal consequence that follows from the application.
5. **Weak-link test** - mark which elements are contested in interpretation, which facts are
contested on the evidence, and which assumptions were made silently. This is the map for
