Both the National University of Singapore Law Faculty and the Singapore Law Review recommend that when citing Singaporean law, students should follow the Canadian Guide to Uniform Legal Citation.
A print copy of the Canadian Guide is available in the LawBod at the shelfmark Ref Bibl Cw Can C213c.
As the LawBod holds an earlier edition of the Guide, we would reccommend that you use a more recent online resource. A full copy of the Guide is not currently available online, but a useful summary based on the 6th edition of the Guide is available at the following link: Canadian Guide to Uniform Legal Citation.
