In the context of devolution, roughly half of all Acts of Parliament apply to only part of the UK, with some 30 per cent applying only to England and Wales. How to deal with such legislation in Westminster (or "English votes for English laws") is the perennial West Lothian Question.

Due to report by May 2013, two of its Commissioners will be discussing the Commission's findings following their 17-month investigation.
