Parliament Acts 1911 and 1949

The Parliament Acts 1911 and 1949 are two Acts of the Parliament of the United Kingdom, which form part of the constitution of the United Kingdom. Section 2(2) of the Parliament Act 1949 provides that the two Acts are to be construed as one.

The Parliament Act 1911 (1 & 2 Geo. 5. c. 13) asserted the supremacy of the House of Commons by limiting the legislation-blocking powers of the House of Lords (the suspensory veto). Provided the provisions of the Act are met, legislation can be passed without the approval of the House of Lords. Additionally, the 1911 Act amended the Septennial Act 1716 to reduce the maximum life of a Parliament from seven years to five years. The Parliament Act 1911 was amended by the Parliament Act 1949 (12, 13 & 14 Geo. 6. c. 103), which further limited the power of the Lords by reducing the time that they could delay bills, from two years to one.
