Baroness Murphy’s post reminds me of a question frequently raised in discussions about the Lords. Can peers vote in parliamentary elections? The answer is no. Or rather, members of the House of Lords cannot vote in parliamentary elections. Prior to 1999 it was held in common law that it was the status of being a peer that precluded one being able to vote. Since 1999 (and the House of Lords Act) it is the fact of being a member of the second chamber that prevents one from voting. Hereditary peers who are excluded from membership of the House are able, under the terms of the 1999 Act, to vote.
Members of the Lords can vote in all other (European, local etc) elections. Some members of the House object to being prevented from voting in elections to the House of Commons and are pressing for a change in the law.
As various observers take pleasure in pointing out, members of the Lords – in being denied the right to vote – are in the same category as people under the age of 18, aliens, prisoners, and persons of unsound minds.
