Halsbury's Statutes annotations are derived from the notes that appear in the volumes of Halsbury's Statutes of England and Wales. These notes provide precise information relating to:

* commencement
* parliamentary debates and, where appropriate, the background to legislation
* words and phrases defined statutorily
* judicial interpretation of statutes, whether of individual words and phrases, or sections as a whole
* cross-references to other provisions of the Act and to other relevant legislation
* subordinate legislation
* the origin of consolidating legislation

The notes are updated weekly to reflect changes brought about by new cases and new legislation. The notes are completely revised whenever a volume of Halsbury's Statutes is reissued in print.
