The European Union is a partnership between member states (currently 28). The UK joined in 1973, but gave notice on 29 March 2017 that it is going to leave.
The EU has its own legislature and executive, as well as an independent judiciary, with powers conferred through the founding Treaties.
A detailed online guide to all legal and institutional aspects of the European Union is regularly updated by the European Parliament. It is available online as Fact sheets on the European Union.
You have access to many law books related to EU Law. Where possible, books are made available in ebook format for improved accessibility. Use Library Search to find books available to you in print and electronic form at the University. You can search by author, title or topic to discover relevant books.
The print copies of books are available in the Law Library and are classified according to the Moys Classification scheme.

You have access to many law related journals and these are primarily available in online format. The print copies of journals are available on rolling shelving in the Law Library. Take a look at the Law Journals Guidance for detailed information on all aspects of finding law journals.
Use the catalogue tab on Library Search to search for a journal title, e.g. Common Market Law Review. You can then use the online links to access the full text journal.
Not every law journal title appears in the library catalogue - for example there are many journals only accessible within Lexis/Westlaw or other databases Try the catalogue first , then check the databases, and just email the Library Liaison Team if you need help.
Use the Articles + more tab on Library Search and enter your search terms. This will help you discover journal articles, reports, book chapters and conference proceedings.
Not all journal content is accessible via Library Search so you will need to use the legal databases for comprehensive searching.
This example shows a selection of journal articles relating to EU law and Brexit.

About the Court of Justice of the European Union
The Court of Justice of the European Union (CJEU) is the judicial authority of the European Union. It oversees the uniform application and interpretation of European Union Law in co-operation with the national judicial systems of the national states. The CJEU resolves legal disputes between national governments and EU institutions, and may also take action against EU institutions on behalf of individuals, companies or organisations whose rights have been infringed
The CJEU is based in Luxembourg and should not be confused with:
The CJEU is divided into 2 courts:
The European Union Civil Service Tribunal was a specialised court within the CJEU from 2005-2016, and its role was to adjudicate in disputes between the European Union and its civil service. These cases are now heard by the General Court.
Searching online for EU Case Law
The recommended services for online searching for EU case law are the specialiased services:
Eur-Lex: free and official legal server of the European Union. It provides access to all secondary legislation of the European Union and all case law of the CJEU courts. Use the online tutorials for guidance.
You can also search full text EU case law via Lexis and Westlaw.
The ABC of EU Law is a useful reference work to aid understanding the legal order of the EU.
EU Primary Legislation (treaties)
Primary legislation consists of founding, amending and accession treaties which were used to set up and change the constitution of the EU.
The EU treaties are binding agreements between EU member countries. They set out EU objectives, rules for EU institutions, how decisions are made and the relationship between the EU and its member countries. Every action taken by the EU is founded on treaties.
The easiest database to use for treaty research is Eur-Lex - Treaties but you can also use Lexis and Westlaw for treaty research.
EU Secondary Legislation (regulations, directives, decisions etc.)
EU secondary legislation consists of various legal instruments
The easiest resources to use for legislation research is EUR-Lex - Legislation, but but you can also use Lexis and Westlaw to find the various legal instruments.
Tracking legislative progress
You can use EUR-Lex's Legislative Procedures to follow the life cycle of a legislative proposal from the moment it is launched until the final law is adopted.
The European Parliament's Legislative Observatory enables you to follow the decision-maling process for all EU legislative and non-legisaltive procedures going through the European Parliament
The Official Journal - OJ
The Official Journal of the EU - known colloquially as the OJ - is the official gazette of the EU. It has two main series:
EUR-Lex provides easy access to all OJ content.
COM Docs - (Commission Documents)
COM Docs are a series of official publications produced by the European Commission for the attention of other EU institutions, such as the Council of the EU or the European Parliament. They have reference numbers prefixed 'COM' (standing for 'Commission'), for example, COM (2018) 231.
They include numerous different types of document, such as proposals for legislation, green papers, white papers and reports on the implementation of policy. They are accessible online via EUR-Lex.
Other EU Official Publications
Use Europa to explore other official publications from the various EU institutions.
When submitting academic work for assessment, you must provide full details of all of the sources you consulted.
For detailed assistance, check out the Citing Legal Sources support guide.
A referencing standard called OSCOLA (The Oxford University Standard for Citation of Legal Authorities) has been developed to facilitate accurate citation of authorities, legislation, and other legal materials. It is widely used in law schools and by journal and book publishers in the UK and beyond. OSCOLA is edited by the Oxford Law Faculty, in consultation with the OSCOLA Editorial Advisory Board.
You can view or download the full 4th edition of OSCOLA to help you format your references.
An OSCOLA Quick Reference guide, is also available and addresses commonly used legal materials including EU law examples.
CJEU cases and the ECLI
The OSCOLA editorial board will discuss treatment of the European Case Law Identifier when preparing the 5th edition. In the meantime, writers who wish to include the ECLI when citing cases from the Court of Justice of the European Union should treat it much like a neutral citation, adding it after the case name and before the report citation. For example:
Case C-176/03 Commission v Council EU:C:2005:542,  ECR I-7879.
For unreported cases, cite the ECLI rather than the OJ notice or the court and date (as advised in OSCOLA 2.6.2). For example:
Case C-542/09 Commission v the Netherlands EU:C:2012:346.
EU legislation – numbering change
Please note that from 1 January 2015 onwards, the numbering of EU legislation has changed, and that under the new approach EU legislation will bear a unique, sequential number. This number should be cited in the form: (domain/body) YYYY/no. For example:
Council Regulation (EU) 2015/159 of 27 January 2015 amending Regulation (EC) No 2532/98 concerning the powers of the European Central Bank to impose sanctions  OJ L27/1
Council Decision (CFSP) 2015/236 of 12 February 2015 amending Decision 2010/413/CFSP concerning restrictive measures against Iran  OJ L39/18
The numbering of documents published before 1 January 2015 remains unchanged (see OSCOLA 2.6.1).
At first, legal citations can seem daunting. Take advantage of the wealth of support material that is available online to help you build your skills and confidence.
Numerous other guides are available. Here is a selection of our favourites, which include plenty of worked examples so you can see how to cite in practice:
Referencing: law resources produced by Southampton Solent University
The University of South Wales Guide to OSCOLA Referencing- both provide lots of helpful guidance and examples to assist students with OSCOLA.
Finch and Fafinski, who author a number of student friendly legal skills materials, also provide a free downloadable guide to answer some common referencing queries and introduce you to the basics of OSCOLA referencing for legal materials.
You will find lots of Brexit discussion material in the legal literature and in other subject disciplines such as politics, business etc.
This topic is also heavily featured in the news resources.
Use Library Search as a starting point to find recent full text material on Brexit issues. This example shows a selection of journal articles relating to EU law and Brexit.
