Statutory Instrument

In many countries, a statutory instrument is a form of delegated or secondary legislation.

Statutory instruments are the principal form in which delegated or secondary legislation is made in Great Britain. The process of creating statutory instruments is governed by the Statutory Instruments Act 1946. This Act replaced the previous system in which statutory rules and orders were made under the Rules Publication Act 1893. The change took place in 1948.

The advent of devolution to Scotland and Wales in 1999 resulted in many powers to make statutory instruments being transferred to the Scottish Government and Welsh Assembly Government respectively. Instruments made by the Scottish Government are now classed separately as Scottish statutory instruments.

In Northern Ireland, delegated legislation is organised into statutory rules, rather than statutory instruments.

In the Republic of Ireland the term "statutory instrument" is given a much broader meaning than under the UK legislation. Under the Statutory Instruments Act 1947 a statutory instrument is defined as being "an order, regulation, rule, scheme or bye-law made in exercise of a power conferred by statute."

However, only certain statutory instrument are published and numbered by the Stationery Office, this being mostly where the statute enabling the enactment of delegated legislation required that any such legislation be laid before the Houses of the Oireachtas.
