The recasting of legislation means the adoption, when an amendment is made to a basic instrument, of a new legal instrument which incorporates the said amendment into the basic instrument, but repeals and replaces the latter. Unlike formal consolidation, it involves changes of substance. It also gives a comprehensive overview of an area of legislation. The new legal instrument is published in the Official Journal (L series).
