You can use OSCOLA shorthand if referring to a source you have already referenced in full.
You do not have to use Ibid but you can.
Example 1 for a book:
In Example 1 below, footnote 2 means the same source as footnote 1 but on page 152, rather than page 150. Footnote 3 means exactly the same source as footnote 2.
¹Samira Ahmed, Law (2nd edn, OUP 2024) 150.
²ibid 152.
3ibid.
Example 2 for a case, page 5 of OSCOLA guide:
'In this example, a citation for Austin v Commissioner of Police for the Metropolis is provided in footnote 1. As the name of the case is given in the text, it is not given in the footnote. The second citation at footnote 2 pinpoints several paragraphs in the case with an attribution to the relevant judge in brackets. The third citation at footnote 7 gives a short form of the case name and a cross-citation to the full citation.
¹[2009] UKHL 5, [2009] AC 564.
²ibid [34] (Lord Hope), [39] (Lord Scott), [43]–[47] (Lord Walker), [58]–[60] (Lord Neuberger).
…
⁷Austin (n 1).'
Example 3 for legislation, page 6 of OSCOLA guide:
'This example shows legislation for which a short form could be used in a subsequent citation. The short form is indicated in brackets at the end of the full citation. In such cases, the short form can be used without a cross-citation to the full citation where the proximity of the full citation enables this to be done without confusing the reader. Where that is not the case, a further full citation should be provided, with the result that cross-citation is never necessary.
³²Council Directive (EC) 93/104 concerning certain aspects of the organisation of working time [1993] OJ L307/18 (Working Time Directive).
…
⁴⁰Working Time Directive, art 2.'
Example 4 for multiple works by the same author, page 6 of OSCOLA guide:
'In this example, two different works by the same author are cited. The subsequent citation provides the author’s surname and the title of the work, or a short form of the title.
²⁷Andrew Ashworth, ‘Testing Fidelity to Legal Values: Official Involvement and Criminal Justice’ (2000) 63 MLR 633, 635.
²⁸Andrew Ashworth, Principles of Criminal Law (6th edn, OUP 2009) 68.
…
³⁵Ashworth, ‘Testing Fidelity to Legal Values’ (n 27) 635-37.
…
⁴⁶Ashworth, Principles of Criminal Law (n 28) 73.'
Example 1:
In Example 1 below, footnote 3 introduces a new source. Footnote 4 is a cross-reference to footnote 1; '(n1) 153' means the citation is to footnote 1 page 153. If footnote 4 used ‘ibid’ it would mean footnote 4 is the same source as footnote 3.
¹Samira Ahmed, Law (2nd edn, OUP 2024) 150.
²ibid 152.
