Statutory Instrument of the Welsh Assembly [from Electronic source using OSCOLA]


The text of electronic and print versions will be identical, therefore there is no need to give details of the origin of the source you have used.

A statutory instrument is also known as an SI.

When using legislation in your work you must be clear as to whether or not you are dealing with the law as it was passed by Parliament initially, or the law as in force currently.

When looking at legislation online, you should rely on trusted sources such as The Office of Public Sector Information or the British and Irish Legal Information Institute. However, these sites give the law as it was passed and do not reflect repeals and amendments. Even the Statute Law Database is currently only up to date as far as 2002 with its amendments. It is better to use a database such as Lexis Library or Westlaw as you will find that the text you are looking at is consolidated and includes amendments and repeals to within the last month. This means you will be looking at the law as in force.

As a footnote:

Title of Statutory Instrument Year, SI number Section if required.

In the case of Statutory Instruments from the Welsh Assembly, the word Wales is normally included in brackets in the short title unless the Act is obviously a local one. Abbreviations of sections of statutory instruments are only to be used in footnotes. When referring to a section of an SI in the text, pinpoint references should be written in full, e.g.

The application of rule 2 of the Town and Country Planning (Amendment of Appeals Procedures) (Wales) Rules 2007/2285, in particular sub-section 2(a), has shown that ...

Regulation 4 of the Control of School Premises (Wales) Regulations 2008/136 states that ...


Control of School Premises (Wales) Regulations, 2008/136 reg 4.

Town and Country Planning (Amendment of Appeals Procedures) (Wales) Rules, 2007/2285 r 2.
