Reliance Interests in Statutory and Constitutional Interpretation

People and companies rely on public law when they plan their activities; society relies on legal entitlements when it adapts to new technology, economic conditions, and social groups; legislators, administrators, and judges rely on settled law when they pass, implement, and interpret statutes (respectively). Such private, societal, and public "reliance interests" are the "dark matter" of America's law of interpretation. They underwrite most interpretive doctrine, and their perceived force broadly and deeply affects the application of doctrine.
