members of legislatures of non-Commonwealth countries, other than Ireland
holders of certain administrative and diplomatic offices
all members of certain bodies, such as tribunals and government departments, plus some statutory corporations such as Channel 4
Lords Lieutenant, High Sheriffs and the Governor of the Isle of Wight are also disqualified from seats for constituencies within their area. Section 2 limits the number of government officials in the House of Commons at any one time to 95. Any appointed above that limit are forbidden to vote until the number is reduced to 95. Section 4 effectively adds the Crown Stewards and Bailiffs of the Chiltern Hundreds and of the Manor of Northstead to Part III to Schedule 1, thus naming them as offices whose holders are disqualified. These offices are sinecures, used in modern times to effect resignation from the House of Commons. Prior to 1926, this disqualification was due to them being "offices of profit under the Crown", but that disqualification was abolished in 1926 and by s. 1 of this Act. The election to the Commons of a disqualified person is invalid, and the seat of an MP who becomes disqualified is vacated immediately. The Privy Council has jurisdiction to determine whether a purported MP is disqualified; the issue may be tried in the High Court, Court of Session or High Court of Northern Ireland as appropriate for the constituency.
Amendments
This Act was amended by subsequent legislation:
The Disqualifications Act 2000, a consequence of the Good Friday Agreement, added the words "other than Ireland", prior to which Irish legislators were disqualified just as any other foreign legislators are. This was to bring them in line with treatment of Commonwealth legislators; however, as of 2016 no one has taken advantage of this privilege.
Previously, all ministers of the Church of Scotland, priests, and deacons were disqualified. The House of Commons Act 2001 restricted this disqualification to only Lords Spiritual, i.e. the most senior Anglican bishops who already sit in the House of Lordsex officio.
Various enactments have amended the lists of disqualified bodies and offices, particularly as they have come in or out of existence or fallen out of government control. For example, employees of British Gas were disqualified until the company was privatised.
