Act passed in the British Parliament that deprived the House of Lords of its absolute power of veto on legislation.
Proposed by a Liberal majority in the House of Commons , the act stated that any bill passed unchanged by the Commons in three separate sessions over two years could be presented for the royal assent (necessary for a bill to become law) without the Lords' consent. By subordinating the Lords to the Commons, the act was seen as another step in making the British Constitution more democratic.
