So, you collected the relevant materials for your research, went through them carefully, and evaluated the available materials. Now, what remains is to carefully dot down your arguments in your own words while supporting those arguments and ideas by citing relevant materials in the footnotes.
It is necessary to cite relevant legal material that you have referred to because it reflects your research and in-depth study that you have undertaken to write that paper. Apart from that, while quoting the work of someone else, citation is necessary to avoid possible allegations of plagiarism.
However, while citing the materials in the footnotes section, you cannot cite them as per your wish. For example, while citing page no. 99 of ‘The Start-up of You’ book written by Reid Hoffman, you cannot cite it as ‘page 99, The Start-up of You, Reid Hoffmann’ just because that seems convenient. There is a standard method to cite legal documents and you must conform to that standard so as to ensure the fulfilment of basic research requirements.
There are basically two standard methods to cite a legal resource (there are many other, but these two are commonly accepted): the Bluebook system of citation, or the OSCOLA system of citation. Herein, we’ll be discussing about the bluebook system of citation in short.
