Despite much criticism the House of Lords continues to play an important role scrutinising and revising government legislation. The bulk of its members are appointed for life. Sitting independently outside of narrow party politics, peers do not have to seek regular re-election. This allows them more time to scrutinise and debate legislation, and ensures that they are not beholden to one particular party leader. The current political make-up of the Lords also means that the Government does not have a majority, making it in some senses the real opposition as it has the numbers to amend and defeat legislation, forcing the Government to rethink its approach.
The lack of democratic accountability in the House of Lords undermines its legitimacy and the UK's credibility as a whole. It gives outsiders the impression that cronyism and nepotism remain a large part of British society. Despite the Government not having a majority, peers in the House of Lords fear its eventual abolition and often will only oppose or revise government legislation to the extent that it may cause minor irritation but not a serious obstacle. The lack of democratic legitimacy has allowed previous governments to introduce legislation to curtail the power of the Lords, ensuring that it cannot operate with the same power of an elected upper chamber.
