OSCOLA Citation Style for UK Law 2026: Complete Guide (Oxford Standard)

OSCOLA (Oxford Standard for the Citation of Legal Authorities) is widely used for UK legal writing. The Oxford University Faculty of Law published the 5th edition on 25 March 2026. This guide covers OSCOLA's footnote conventions and reference rules for cases, legislation, secondary sources, EU law and international law.

This practical summary was checked against the official OSCOLA resources from the University of Oxford Faculty of Law (https://www.law.ox.ac.uk/oscola). The official manual and any faculty-specific guide remain authoritative.

What Is the Latest OSCOLA Edition?

The current edition is OSCOLA 5th edition, published on 25 March 2026. It incorporates and updates international-law guidance in the main manual. The 2012 fourth edition and its earlier supplements remain previous-edition material, not the standard for a new document unless an institution explicitly requires them.

What OSCOLA Is, and When to Use It

OSCOLA was developed at the Oxford University Faculty of Law by Professor Peter Birks in 2000, with subsequent editions maintained by the Faculty's editorial team. Many UK law schools, journals and publishers use it, but the assigned faculty or publication guide remains binding.

Disciplines using OSCOLA:

• UK common law (England, Wales, Scotland, Northern Ireland)
• Comparative law (often with adaptations for civil law jurisdictions)
• European Union law (integrated into the 5th edition)
• International law (integrated and updated in the 5th edition)
• Some Commonwealth jurisdictions adapt OSCOLA for local use

If you are studying law in the UK, check whether your faculty requires OSCOLA 5 or maintains a local variant. For US legal writing, see Bluebook 22 (https://www.legalbluebook.com).

Core OSCOLA Rules

OSCOLA is fundamentally different from APA, MLA, Chicago, Vancouver and IEEE in two critical ways: it uses footnotes for all citations (no in-text parenthetical), and its primary objects are legal authorities (cases, statutes) rather than scholarly works.

Footnotes only

OSCOLA uses footnotes for all citations. There is no in-text parenthetical system. Every citation, every source, every reference is in a footnote.

The leading case is Donoghue v Stevenson.¹

Footnote:

1. Donoghue v Stevenson [1932] AC 562.

No bibliography by default

For shorter works, OSCOLA does NOT require a bibliography. Citations are complete in the footnotes. For longer works (theses, dissertations), a table of authorities and a bibliography are usually required.

No ibid. in the 5th edition

OSCOLA 5 removes ibid.. Use a shortened citation that points back to the first full footnote:

1. Donoghue v Stevenson [1932] AC 562, 580.
2. Donoghue (n 1) 581.

The "(n 1)" notation refers back to footnote 1.

Citing Cases

Cases are OSCOLA's primary objects. The format is specific and rigorous.

Modern UK cases (after 2001 with neutral citation)

Smith v Jones [2024] UKSC 12, [2024] AC 1234.

Format: Case name [Year of judgment] Court abbreviation Case number, [Year of report] Report abbreviation Volume Page.

Components:

• Case name (in italics, "v" lowercase between parties, NOT "vs" or "v.")
• [Year of judgment] in square brackets
• Court abbreviation (UKSC = UK Supreme Court, EWCA Civ = England & Wales Court of Appeal Civil Division, EWHC = High Court, etc.)
• Case number (the number assigned by the court)
• Comma, then traditional report citation: [Year of report] Report Volume Page

Older UK cases (before 2001, no neutral citation)

Donoghue v Stevenson [1932] AC 562.

Format: Case name [Year] Report Volume Page.

Common report abbreviations:

• AC = Appeal Cases (House of Lords / Supreme Court)
• WLR = Weekly Law Reports
• All ER = All England Law Reports
• QB or KB = Queen's Bench / King's Bench Division
• Ch = Chancery Division
• Fam = Family Division

Quoting from a specific page

Donoghue v Stevenson [1932] AC 562, 580.

The number after the comma is the specific page number where the quoted passage appears.

Case names

• Use italics for the case name (Donoghue v Stevenson)
• Use lowercase "v" between parties (not "vs" or "v.")
• For a person, surname only (Donoghue, not Mrs. Donoghue)
• For an organization, the standard short form
• Court details immediately after, in square brackets

Citing Statutes

Act of Parliament (UK)

Companies Act 2006, s 994.

Format: Act name Year, s section number.

Common abbreviations:

• s = section (s 994)
• ss = sections (ss 1-10)
• sub-s = subsection (sub-s (1))
• para = paragraph
• Sch = Schedule

For a specific subsection:

Companies Act 2006, s 994(1)(a).

Statutory Instrument (SI)

Companies (Disclosure of Directors' Information) Regulations 2009, SI 2009/3000.

EU Law

OSCOLA 5 integrates its EU and international-law guidance into the main edition:

Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 (General Data Protection Regulation) [2016] OJ L119/1.

For directives, regulations, decisions: follow the format above with the appropriate body and OJ (Official Journal) citation.

Treaties

Treaty on the Functioning of the European Union (Consolidated Version) [2012] OJ C326/47.

Citing Books

Cross-References and Footnote Conventions

Shortened note (subsequent citation)

After the first full citation, use a shortened form referencing the previous footnote:

First citation:

1. Donoghue v Stevenson [1932] AC 562, 580.

Subsequent citation:
5. Donoghue (n 1) 580.

For statutes:

First: Companies Act 2006, s 994.
Later: Companies Act 2006, s 994 (or just CA 2006, s 994).

For books:

First: Hugh Collins, The Law of Contract (4th edn, LexisNexis 2003).
Later: Collins (n 1) 100.

Consecutive citations

OSCOLA 5 removes ibid.. Use the same shortened cross-reference form for consecutive and non-consecutive citations:

1. Hugh Collins, The Law of Contract (4th edn, LexisNexis 2003) 100.
2. Collins (n 1) 102.

Cross-reference to your own discussion

To cross-reference your own earlier or later discussion:

See above ch 3.
See below ch 5.2.

Manuscript Formatting (UK Legal Conventions)

For law theses and dissertations, layout conventions are typically:

Margins

1 inch all sides; some universities specify 1.25" left for binding.

Font

Times New Roman 12pt body, Times New Roman 10pt for footnotes.

Spacing

Body text: 1.5 or double-spaced (varies by university). Footnotes: single-spaced.

Headings

Numbered hierarchy: Chapter 1, 1.1, 1.1.1. Use consistent formatting.

Footnotes

Footnotes at the bottom of each page, sequentially numbered through the entire thesis (not restarting each chapter).

Table of authorities

For longer works (PhD theses), a Table of Authorities at the start lists all cases, statutes, and secondary sources cited:

• Cases section: alphabetical by case name
• Statutes section: by year of enactment
• Secondary sources section: alphabetical by author

Bibliography (optional, for theses)

Bibliography organized by source type (books, journals, cases, statutes), alphabetical within each section.

Common Mistakes That Lose Marks

Five mistakes that supervisors and journal editors flag most often.

Italicizing journal titles: OSCOLA does NOT italicize journal titles (only book titles and case names). Most common APA/MLA carryover.

Using "vs" or "v." in case names: OSCOLA uses lowercase "v" between parties. Not "vs", not "v.".

Wrong court abbreviations: each court has a specific OSCOLA abbreviation. UKSC, EWCA Civ, EWHC are not interchangeable. Use the correct one.

Missing pinpoint references: when citing a specific page, paragraph or section, use a pinpoint after the citation:

Donoghue v Stevenson [1932] AC 562, 580.

Without the page number, you're citing the entire case rather than the specific passage you're discussing.

Using parenthetical citations: OSCOLA uses footnotes only. APA-style in-text citations are not OSCOLA.

Reference Managers and OSCOLA

Reference-manager styles may lag behind the new edition. Oxford's support page warns that some linked styles still relate to OSCOLA 4, so verify the generated output:

• Zotero: confirm that the installed style explicitly supports OSCOLA 5
• Mendeley: compare generated citations with the 5th-edition manual
• EndNote: verify the output style version before final submission
• Westlaw UK / Lexis+ UK: legal databases with OSCOLA-format citation export
• Folio Student: applies OSCOLA layout for UK law thesis projects

For law students, Westlaw UK and Lexis+ UK (subscription databases via your university library) are particularly useful: they generate OSCOLA-formatted citations for cases and statutes automatically.

FAQ

What is the current OSCOLA edition in 2026?

OSCOLA 5 is current. The Oxford Faculty of Law published it on 25 March 2026 and lists the fourth edition as the previous edition.

Why does OSCOLA use footnotes only?
Legal writing relies on dense citation to cases and statutes. Parenthetical in-text citations (Smith, 2024) become cluttered in legal arguments that may cite 10-20 sources per page. Footnotes keep the main text readable while allowing precise citation.

What's the difference between OSCOLA and Bluebook?
OSCOLA 5 is widely used in UK legal writing, while Bluebook 22 is widely used in US legal writing. They use different citation forms, court abbreviations, statute formats and secondary-source conventions. Follow the guide assigned by the faculty, journal or court.

How do I cite a UK Supreme Court case in OSCOLA?
For cases since 2001 (neutral citation era):

Smith v Jones [2024] UKSC 12, [2024] AC 1234.

Include the neutral citation [2024] UKSC 12 and the traditional report citation [2024] AC 1234. UKSC = UK Supreme Court.

How do I cite an Act of Parliament?

Companies Act 2006, s 994.

Italicize the Act name? No, Acts are in plain text in OSCOLA (only case names and book titles are italicized).

How do I cite generative AI in OSCOLA 5?

The 5th edition adds specific guidance for generative AI in section 3.7.13. Apply that rule to the exact material used, and separately follow your university's policy on permitted use, disclosure and retention of prompts or outputs.

Should I include a bibliography in my law thesis?
For undergraduate essays (3000-5000 words): usually no, citations are complete in footnotes. For master's dissertations and PhD theses: yes, plus a Table of Authorities listing all cases and statutes cited. Check your supervisor's expectations.

How do I cite a journal article in OSCOLA?

Hugh Collins, 'The Sanctity of Contract Reaffirmed' (2018) 81(4) Modern Law Review 503.

Author name first (first name first, plain text). Article title in single quotes. Year in parentheses, volume, issue, journal title (NOT italicized), starting page.

What if I'm citing a Scots law case?
Scots cases use the same OSCOLA format with Scottish court abbreviations (CSIH for Inner House, CSOH for Outer House). For criminal cases: HCJ (High Court of Justiciary). Always include the neutral citation where applicable.

Can I use shortened forms after the first citation?
Yes, OSCOLA explicitly endorses shortened forms after first full citation:

First: Donoghue v Stevenson [1932] AC 562, 580.
Later: Donoghue (n 1) 580.

For statutes:

First: Companies Act 2006, s 994.
Later: CA 2006, s 994.

How do I cite Hansard (UK parliamentary debates)?

Hansard HL Deb 5 March 2024, vol 836, col 1234.

HL = House of Lords, HC = House of Commons. Date, volume, column number.

Should I include a Table of Authorities at the start of my thesis?
For PhD theses and master's dissertations in law: yes, recommended. Organized by source type:

• Table of Cases (alphabetical by case name)
• Table of Statutes (chronological)
• Table of Statutory Instruments
• Bibliography of Secondary Sources

This is a hallmark of professional UK legal writing and is often required by law programs.
