Chapter 14Interpretation, Principles and Institutional Reason
What makes an explanation of an outcome a legal justification that an institution can answer for, and what follows for an outcome for which no justification is available?
The chapter develops
The Reasoned Legality Principle, with two routes to accountable reasons at the legally relevant unit of judgment: the standing rule, deployment, batch or individual case.
The Reasoned Legality Principle
Technical explanation and prediction cannot substitute for legal justification.
Doctrine 6 of the Book’s twenty-one. A proposed formulation, not an enacted rule.
Summary
An outcome can possess a valid pedigree and still lack a legal justification. This chapter develops the proposed Reasoned Legality Principle by distinguishing technical explanation, institutional reasons and the warrant for a particular exercise of power. Engagement with rules, standards, principles and interpretive methods exposes choices concealed in coefficients, defaults and apparently settled classifications. The chapter tests generated reasons against competing accounts of assessment and ownership, reconciling them through a dual-track canon. Routine determinate applications may use Assessed Reasons verified against an approved, versioned legal rule model; judgments requiring discretion, resolution of material dispute or particular coercive consideration require meaningfully Owned Reasons. A record must identify the relevant unit of judgment and permit challenge to its classification. Comparative reason-giving and explanation duties remain distinct from the proposal. The absence of available justification makes an outcome ‘not legally established’, without imposing a universal nullity rule or confusing faithful later articulation with fabricated deliberation.
