Boundary Commission (United Kingdom)
:
Boundary Commission redirects here. For the historical commission in Ireland, see
Boundary Commission (Ireland).In the
United Kingdom, the four
Boundary Commissions are responsible for determining the
boundaries of
House of Commons constituencies. There is one Boundary Commission each for
England,
Scotland,
Wales, and
Northern Ireland. The Commissions are currently established under Parliamentary Constituencies Act 1986 (as amended by the Boundary Commissions Act 1992), although they were first established under early legislation after the Second World War. The Boundary Commissions will cease to exist after they complete their present review. Their functions will be transferred to the
United Kingdom Electoral Commission.
The Commissions conduct a review once in eight to twelve years. There are four members of each Commission, of which three actually take part in meetings. The
Speaker of the House of Commons is the
ex officio Chairman of each Boundary Commission, though he takes no actual part in the proceedings. The Deputy Chairman of a Commission, who actually presides over Commission meetings, is always a Justice in a British court.
Once in 8-12 years, the Commission conducts a complete review of all constituencies. In between general reviews, the Commission conducts interim reviews, considering one geographic area at a time. The interim reviews usually do not yield drastic changes in boundaries, while the general reviews often do. The next review is due to be complete by
April 12,
2007 with the new boundaries used for the
next general election.
Under the rules established by Parliament, the number of constituencies in Great Britain (England, Wales, and Scotland) must not be "substantially greater or less" than 613, of which at least 35 must be in Wales. The
City of London must not be partitioned and must be included in a seat that refers to it by name. The
Orkney and
Shetland islands may not be combined with any other areas. Northern Ireland may include 16-18 constituencies.
The Boundary Commissions are required by law to take
local government boundaries into account when determining constituencies. The Commission, however, may choose to deviate from this requirement if failing to do so would cause some constituencies to be widely disparate in size.
Once the Commission makes a report, the recommendations must be submitted to
Parliament. The Parliament may approve or reject these recommendations, but it may not amend them. If Parliament approves the recommendations, then the
Sovereign may make an Order formalising the boundary changes.
