Provision-level reads are the main path; an item-level read returns the whole text only for small items and otherwise an outline of provision paths to read next. With match_text (item level), returns the provisions whose text matches. Revised text is an editorial consolidation that can lag: read editorial.caveat and unapplied_effects before relying on it, and use uklaw_get_amendments for every recorded effect on an item, applied or not.Read one item or one provision of UK legislation from legislation.gov.uk — as it stands now (revised), as enacted/made, or as it stood on a date — in Markdown, with its editorial status, annotations (the applied amendment history), the unapplied effects touching it, the versions available, and attribution.
