INTRODUCTION

English translation pending.

CORE DEFINITION

IRAC is the standard structure for legal analysis and legal writing. Issue identifies the legal question the facts raise. Rule states the relevant legal rule, usually drawn from statute or case law. Application applies that rule to the specific facts, which is the analytical core of the method. Conclusion states the legal result that follows. The structure's premise is that legal reasoning must show the path from rule to outcome rather than assert the outcome, and the application step is where that path is either demonstrated or missing. Variants such as CREAC reorder the conclusion to the front but keep the same components.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use issue framing: state the legal question in a single sentence before discussing anything else. - Use rule sourcing: cite the governing rule precisely rather than paraphrasing from memory. - Use fact mapping: connect each element of the rule to specific facts in the record.

Anchor fast decisions

Legal outcomes depend on whether a rule's elements are satisfied by the facts, and the mapping between them is where reasoning either holds or fails. Stating the issue first bounds the analysis so the rule search is targeted. Applying the rule element by element to the facts makes each step inspectable, so a conclusion that does not follow becomes visible rather than merely asserted. Separating rule from application also keeps precedent and facts distinct, which lets another reader check the reasoning against the same materials.
