PATTERN: style of cause, neutral citation, pinpoint [if needed], judge [if needed].
EXAMPLE: Clearbrook Iron Works Ltd v Letourneau, 2006 FCA 42.
Let's examine each part of the citation for a case with a neutral citation to understand how it is constructed:
example: Clearbrook Iron Works Ltd v Letourneau
"Indexed as": for recent cases, an "indexed as" title will appear at the beginning of a case. If you are ever in doubt as to what the style of cause for a case should be, this is a useful bit of information. Check the first page of the judgment and if the case has an "indexed as" reference, use it for citation purposes.
Reference to the Crown: As an element of constitutional monarchy, Canadian executive government authority is formally vested in the Queen, hence the use of "R" for the Latin word for queen, regina, in legal citations. This is used mainly for criminal cases prosecuted by the state, although you may also see R as part of a citation for a civil case, in place of such terms as "The Queen", "The Queen in right of," etc.
Use the neutral citation as given by the court.
example: Clearbrook Ironworks Ltd v Letourneau, 2006 FCA 42
Include a pinpoint if you are citing to a particular passage in the judgment. Since your case has a neutral citation, make sure you cite to the paragraph number.
example: Clearbrook Ironworks Ltd v Letourneau, 2006 FCA 42 at para 3
If relevant, the judge's name may be included, followed by "J" for Justice, "JA" for Justice of Appeal, etc. (consult 3.10 of the McGill Guide).
example: Clearbrook Ironworks Ltd v Letourneau, 2006 FCA 42 at para 3, Sexton JA.
