Policy Note
Policy Note sets out a brief statement of the purpose of a Scottish Statutory Instrument and provides information about its policy objective and policy implications. They aim to make the Scottish Statutory Instrument accessible to readers who are not legally qualified and accompany any Scottish Statutory Instrument or Draft Scottish Statutory Instrument laid before the Scottish Parliament from July 2012 onwards. Prior to this date these type of notes existed as ‘Executive Notes’ and accompanied Scottish Statutory Instruments from July 2005 until July 2012.

Timeline of Changes
This timeline shows the different points in time where a change occurred. The dates will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force. The first date in the timeline will usually be the earliest date when the provision came into force. In some cases the first date is 01/02/1991 (or for Northern Ireland legislation 01/01/2006). This date is our basedate. No versions before this date are available. For further information see the Editorial Practice Guide and Glossary under Help.
