The House of Commons (Disqualification) Act 1975 sets out information about who is disqualified from sitting as a Member of the House of Commons. This includes 'offices of profit under the Crown' (but does not include those holders of ministerial office); civil servants; police officers; members of the armed forces; judges; and members of non-Commonwealth overseas legislatures. Those who are also ineligible to vote in a general election, such as Members of the House of Lords; those under 18 years of age; sentenced prisoners and persons detained under the Mental Health Act 1983. In the House of Lords the following rules disqualify a Peer from taking his or her seat: those under 21 years of age; people born outside of England, Scotland, Ireland or specific overseas countries; those convicted of treason; and bankruptcy. The House of Lords Act 1999 removed the entitlement of most of the hereditary Peers to sit and vote in the House of Lords and of the 92 hereditary Peers who retain their seat in the Lords, 75 were elected by their fellow hereditary Peers.
