Work is currently being undertaken to enable mandatory polygraph pilots to begin by April 2009. By virtue of section 41 of the Offender Management Act 2007, sections 28 and 29 may be brought into force by order only in relation to a specified area for a specified time, unless a draft of the statutory instrument containing the order has been laid before, and approved by, each House of Parliament. The legislation was framed in this way in order to allow pilots of mandatory polygraph testing of sex offenders on licence to take place in specified areas before Parliament decides on whether mandatory testing may be rolled out nationally.
