Parliament Act 1911

In Britain, statute severely curtailing the power of the House of Lords and asserting the primacy of the House of Commons. The law, introduced after the Lords rejected Lloyd George's radical People's Budget of 1909, prohibited the Lords from interfering with financial legislation and abolished their power to reject other types of legislation passed by the Commons, restricting them to delaying it for up to two years. The law also reduced the maximum life of a parliament from seven years to five.

The act was fiercely resisted and only received the Lords' assent when George V agreed to create sufficient Liberal peers to force it through. A second Parliament Act in 1949, further limiting the period the Lords could delay legislation to a year, was also strongly opposed and was eventually passed without the Lords' assent under the terms of the 1911 act.
