Earlier this week Westlaw announced the launch of Annotated Statutes. All new Acts, as well as those published since 2007 will be / have been annotated. It is likely that key earlier Acts will be annotated over time.
So, what value do these annotations give to users of Westlaw UK? The idea is that they will explain the effect, purpose and likely application of each Act. More information is available on the Westlaw web site.
To find annotations, search for Legislation in the normal way. If an Act has been annotated an 'A' will appear beneath the Short Title in the results list. Within the Act, general annotations follow on from the Preamble, with section specific commentary appearing underneath the text of each provision. When printing or saving content you can choose to save the annotations.
The best way to find out more about how this new development works is to go into Westlaw UK and have a look for yourself. If you're not sure where to start, the Parliamentary Standards Act 2009 is a topical example.
