I would like to ask for some help with the citation style.
My greatest doubts concern how to cite items I have already cited:
1 Buchan, R. (2012). Cyber Attacks: Unlawful Uses of Force or Prohibited Intervention? Journal Conflict and Security Law, Vol. 17, 2 p. 222, Pdf.
2 Ibid.
3 Ibid., p. 230
10 Bucan, R. (2012) as per supra note 1, p. 245.
Answer
APA style requires parenthetical citations instead of footnotes. Switching to MLA would not solve the issue, since MLA also requires parenthetical in-text citations. A style with footnotes is Chicago Notes & Bibliography Style.
In general, for legal sources, most styles refer to the format given by The Bluebook: A Uniform System of Citation, including Chicago.
With requoted sources, the rule is:
Short Form Citations
Principle: Once a full citation to a case, statute, regulation, book, or journal article has been provided, subsequent references within the same discussion can be less complete. The less complete or “short form” citation must clearly identify the referenced work. Short form citations should only be used where the reader will find it easy to return to the full citation.
Use id. if the authority is the same as the immediately preceding authority. Use supra if not referring to the immediately preceding authority.
