You need to look at the details in the book itself to construct the citation.
The requirements are twofold with legal citation:
Author + Title + (Publisher, edition, year) + Pinpoint.
The full citation to a book or journal article is given only once in the footnotes.
The manner in which a subsequent reference is made depends on whether it is referring to a source in the immediately preceding footnote, or in a previous footnote other than that immediately preceding.
Where the subsequent reference is referring to the source in the previous footnote, i.e. footnote 5 is a subsequent reference to footnote 4, 'ibid' is used (see AGLC rule 1.4.3). Ibid is not to be used where there are multiple sources in the preceding footnote.
Where the subsequent reference is referring to a source other than in the previous footnote, 'above n' is used, where 'n' refers to the number of the footnote being subsequently cited (see AGLC rule 1.4.2).
These notes are not exhaustive, see AGLC rule 6 for other requirements for citing a book in your work.
Author + Title + (Publisher, edition, year)
Note: In a bibliography entry where there is more than one author, only the first author's name is inverted. There is no full stop at the end of the citation in a bibliography (see AGLC rule 1.13).
