Case Law: How to find and use case law: Introduction

What is case law? Where can you find Scottish and English case law? How can you check the status of case law?

Case law

Case law (or judicial precedent) is law which is made by the courts and decided by judges. Judicial precedent operates under the principle of stare decisis which literally means “to stand by decisions”. This principle means that a court must follow and apply the law as set out in the decisions of higher courts in previous cases.

In order for the principle of stare decisis to operate, a judge must know what the previous decisions of courts are. Case reports, or “law reports”, make this possible. Although earlier collections of cases exist, it was in the 19th century that a formalised system of law reporting was established in Scotland and England. There are currently many different series of law reports published, which reproduce judgments and add supplementary information by an editor. It may take some time between a judgment being handed down and its being published as a report. Similar systems of law reporting operate in other common law jurisdictions.

The main sources of cases are law reports, digests and official transcripts.

Case law, like legislation, can change over time. Just because a decision was good law once does not mean it remains so today. A lawyer needs to be able not only to find and read case law, but also to be able to check whether it has been subject to subsequent judicial consideration and whether it remains good law.

Law reports, digests and transcripts

Law reports

Not all cases are reported. Indeed, given the volume of cases passing through the courts, only a small minority of cases are reported.

Whether a case is reported is decided by the editor of a series of reports. Generally speaking, to merit reporting a case must introduce a new legal principle or rule, modify an existing principle or settle a doubtful question of law. A case may be reported if it addresses an issue of statutory interpretation or provides a new application of an accepted principle.


A digest is a publication which contains summaries of cases. Digests can be a useful way of finding and checking the status of a case. They may also be the only source of a case available to you – especially if the case remains unreported. Examples include The Faculty Digest and Shaw’s Digest, which contain information about older Scottish cases. The Current Law Year Book and Monthly Digest also contain summaries of cases.


Transcripts of judgments are documents produced by a court (or reproduced by a publisher) which contain the opinion of the judge(s) with no additional information added. If a case remains unreported, a transcript may be the only source of the judgment. For some cases an application to the court which heard the case is the only method of obtaining a transcript. However, many transcripts are now made available electronically through public access and subscription services. Given the delay in reporting, such services have become an increasingly important source of recent judgments.
