Legal Citations: What Is OSCOLA Referencing?

Have you been asked to use OSCOLA referencing in a document? Or are you writing about UK law and need to know how to cite sources? Well, you’ve come to the right place. In this post, we’ll explain the basics of the OSCOLA system, including how to cite sources and how to compose a bibliography.

What Is OSCOLA Referencing?

The OSCOLA style guide (2012, Hart Publishing)

OSCOLA refers to the Oxford Standard for Citation of Legal Authorities. This style guide, developed by the Oxford Law Faculty, sets out a standard method of legal citation. Currently on its fourth edition, the OSCOLA system has been adopted by most law schools and legal publishers in the UK.

OSCOLA divides sources into ‘primary’ and ‘secondary’ sources. Primary sources are legal sources (e.g. cases and legislation). Secondary sources include everything else (e.g. books, journal articles and websites). Typically, you will cite sources in footnotes in OSCOLA referencing. In addition, most of the time, you will create a list of the sources you have cited for a bibliography at the end of the document.

Primary Sources in OSCOLA Referencing

The format for citing case law in OSCOLA referencing varies depending on whether the case has a neutral citation. This is a unique reference given to a judgment by the UK’s HM Courts and Tribunals Service, making it easier to find judgements (especially for unreported cases).

A neutral citation includes a year, a court abbreviation and a court-assigned number. For instance, we could format a neutral citation as follows:

Case Name

Year of Judgment

Court Abbreviation

Neutral Citation Number

Corr v IBC Vehicles




If you are citing an unreported case, the neutral citation alone will suffice. However, cases from before 2001 may not have a neutral citation. And in most cases, you will also want to cite a law report.

  • Neutral Citation with Law Report

  • Law Report with No Neutral Citation

For UK legislation, you will typically just need the short name and a year:

The concept of heresy changed with the Act of Supremacy 1558.

You can find out more about citing case law and legislation in our blog post here. In addition, OSCOLA has published a supplement [PDF] about citing international law to accompany the third edition. You can use this for reference when citing international or European treaties.

Secondary Sources in OSCOLA Referencing

The format for secondary sources in OSCOLA referencing varies depending on the source type. Citing a print book, for instance, differs from citing a website or online video. However, there are some general principles that apply to various secondary sources, including:

  • Citations should typically provide the author’s first name (or initial) and surname, as well as the source title and publication information.
  • For sources with more than three authors, give the first name listed on the source followed by ‘and others’ in place of the other names.
  • If a source has no named author, use the publishing organisation instead.
  • Italicise titles of books and any other publication with an ISBN.
  • Provide a valid URL for publications that are available online.

For more information on secondary sources, see our blog post on the topic.

How to Create an OSCOLA Bibliography

Officially, the fourth edition of OSCOLA says that ‘shorter works, such as articles and essays, generally only require footnotes.’ As such, you may not need a bibliography at all. However, in practice, most law schools will want you to include one. And in any document more than a few pages long, a bibliography can be very useful for readers.

The rules for composing an OSCOLA bibliography, then, are as follows:

  • Divide the bibliography into three sections titled ‘Table of Cases’ (case law), ‘Table of Legislation’ (legislation) and ‘Bibliography’ (all other sources).
  • List statutory instruments separately at the end of the table of legislation.
  • Do not italicise case names, unlike elsewhere in the text and in footnotes.
  • Use the first significant word from case titles to sort sources alphabetically.
  • If a source has an author, give their surname first, followed by an initial.
  • There is no need for a full stop at the end of bibliography entries.

There is some flexibility in this. For instance, if you have relatively few primary sources, you could list cases and legislation together in a ‘Table of Authorities’. Or if you have cited multiple cases from different jurisdictions, you could list them separately (e.g. ‘UK Cases’ and ‘EU Cases’).

In all cases, though, make sure sources are listed clearly and consistently.

Other Legal Referencing Systems

While OSCOLA is the main form of legal citation in the UK, AGLC referencing is the primary legal citation system in Australia. As such, if you’re writing about Australian law, this is the referencing style you will usually need. Other international referencing systems include:

  • Bluebook referencing – A major legal citation system used in US law.
  • ALWD referencing – A system similar to Bluebook, also used in the US, but with a few simplifications that some say make it easier to use.
