Frequently Asked Questions: Researching UK Law

This guide aims to answer questions frequently asked of the staff at the Inner Temple Library. The sources suggested are not intended to be exhaustive. Rather they are sources that the staff have found to be most useful and which are likely to be found in a chambers library or a public library with a law collection. The sources include free web-based sources, hard copy materials and subscription-based databases. Details of the coverage of the subscription-based databases and other websites can be found at the end of the contents.

Please note that the subscription-based databases mentioned are available for use in the Inner Temple Library by members of the Inns of Court only. These databases cannot be accessed remotely because of restrictions in our licence agreements. Members of the public are advised to contact a public reference library to enquire if these databases are available locally. (Quick Reference Guides to some of the subscription-based databases can be found in the Library Guides section of the website.)

The FAQs are also available as a PDF (Adobe Acrobat Reader required).

Database Coverage

What are Public General Acts (PGAs)?

PGAs are Acts of Parliament which apply to the whole country (i.e. the UK or at least one of its constituent countries). They are distinct from Local and Personal Acts, which apply to a particular individual or to organisations such as local authorities. Back to top.

How do I find when an Act has come into force?

Many Acts have a section which sets out how they will come into force. This is usually placed at or near the end of the main numbered sections, before any appendices. An Act without any commencement provision comes into force straightforwardly on its date of Royal Assent, but if there is such a provision, it may take one or more of various different forms. Some Acts come into force on a specific future date stated in their commencement section, but many are brought into force on one or more unspecified future dates by means of “commencement orders”, which are published as Statutory Instruments. Back to top.

What are Statutory Instruments?

Statutory Instruments (SIs) are the means by which delegated or secondary legislation is made in the UK. Parliament does not have time to administer all the rules and regulations necessary to run the country so it delegates that power to a minister or local authority. The term Statutory Instrument is generic and covers rules, regulations, orders and schemes. Before 1948 delegated legislation was known as Statutory Rules and Orders (SR&Os). Back to top.

What is a neutral citation?

A neutral citation of a judgment identifies it independently of any law report series or other medium or context. It generally consists of the following: year, court, case number, and where appropriate the court division, e.g.  [2003] EWHC 161 (Admin) – referring to case number 161 of 2003 in the High Court (Administrative Court). Many other jurisdictions now have their own systems of neutral citation, which facilitate the retrieval of judgments published on the internet.  Back to top.

What is the difference between a judgment and a law report of a case?

A judgment is the decision of the judge or judges in a court of law. This is distinct from a law report which is produced by a legal publisher with added content such as headnotes and catchwords.  Back to top.

How do I find an unreported case?

Unreported cases can be cited in court and the internet is the best place to look for such judgments. If you cannot find the case via the internet, the Inner Temple Library has produced a guide to locating transcripts of cases. This is called Transcripts of Judicial Proceedings in England and Wales: a Guide to Sources. The guide is available for members of the Inns of Court to consult at the Enquiry Point of the Inner Temple Library. Alternatively it is available to order for free from the website.

Back to top.

If a case is reported in several series of law reports, which report should I use in court?

The most authoritative reports are The Law Reports, which have been produced by the Incorporated Council of Law Reporting (ICLR) since 1865. These should always be used in preference to any other series. The ICLR also produces the Weekly Law Reports (WLRs). The WLRs and All England Law Reports are of equivalent status. If the case is not reported in any of these, you should cite the fullest report you can find. Avoid cases summaries in journals and, where there is no full report, use the official transcript instead.  Back to top.
