For legal passages, the outward level establishes commands, prohibitions, conditions, quantities, and the directly indicated ruling. The inward level can include further conclusions reached through sound implications and indications recognized by legal theory.
Example: examining a quality mentioned with a ruling may help determine its scope or underlying rationale. Yet a merely adjacent quality cannot be declared the legal cause without evidence.
This does not posit a separate secret law. It concerns more demanding inference from the same revealed text, subject to valid proofs, relevant qualifications, and a disciplined method.
