Compound Laws, published by Compound Analytics, reports the record: statutes verbatim, official citations, enforcement facts and verification dates. Nothing here is legal advice and nothing here describes how to get around a law. A jurisdiction with no verified row is reported as not yet verified, never as legal. Found an error?
