13 Law and legal references
13.5.1 UK legislation
A statute’s title should always be in roman, even where a foreign statute is in italics in the original. Older statutes, without a short title, will require the appropriate regnal year (see
Use lower-case Roman numerals in Public (Local) Acts:
Some UK statutes are almost invariably abbreviated, for example PACE (Police and Criminal Evidence Act) and MCAs (Matrimonial Causes Acts). Where such abbreviations will be familiar to readers they may be used, even in text, although it is best to spell a statute out at first mention with the abbreviation in parentheses before relying thereafter simply on the abbreviation. Use an abbreviation where one particular statute is referred to many times throughout the text.
Except at the start of a sentence or when the reference is non-specific, use the following abbreviations: ‘s’, ‘ss’, ‘Pt’, ‘Sch’. For example, paragraph (k) of subsection (4) of section 14 of the Lunacy Act 1934 would be expressed as ‘Lunacy Act 1934, s 14(4)(k)’. There is no space between the bracketed items. In general, prefer ‘section 14(4)’ to ‘subsection (4)’ or ‘paragraph (k)’; if the latter are used, however, they can be abbreviated to ‘subs (3)’ or ‘para (k)’ in notes.
Statutory instruments should be referred to by their name, date, and serial number:
Community Charge Support Grant (Abolition) Order 1987, SI 1987/466
No reference should be made to any subsidiary numbering system in the case of Scots instruments, those of a local nature, or those making commencement provisions.
Quote extracts from statutes exactly. Do not amend to improve the sense, and clearly indicate if you correct obvious errors. Omitted text should be indicated by ellipses.
13.5.2 European Union legislation
For primary legislation, include both the formal and informal names in the first reference to a particular treaty:
Treaty on European Union (Maastricht Treaty), Art G5c
Cite articles of the treaties without reference to the titles, chapters, or subsections. As part of a reference, abbreviate ‘Article’ to ‘Art’, in roman. Cite protocols to the treaties by their names, preceded by the names of the treaties to which they are appended:
EC Treaty, Protocol on the Statute of the Court of Justice
References to secondary legislation (decisions, directives, opinions, recommendations, and regulations) should be to the texts in the Official Journal of the European Union. The title of the legislation precedes the reference to the source:
Council Regulation (EEC) 1017/68 applying rules of competition to transport  OJ Spec Ed 302
While it is always important to state the subject matter of EU secondary legislation, the long official title may be abbreviated provided that the meaning is clear. For example, the full title
