Majority of democratic states have bicameral legislature. In UK the second chamber, the upper house or House of Lords is currently an unelected chamber which use to have judicial (but not now under CRA2005), legislative, scrutinizing and debating functions.
To answer the given question it is important to analyze the functions of House of Lords.
The House of Lords provide a forum for debating and analyzing the matters of public interests which includes the discussions on policies and legislative functions. It provides
Diffusion rather than concentration of power within parliament. The quality of debate is higher than that of commons. Moreover due to lack of procedures in debate it is ensured that the content of bill is fully debated. HOL produce better discussion of any bill and also debates on sensitive issue of the bill regardless of any accountability, because un like common HOL is un elected. Next important issue of HOL is the revision of bill brought from House of Commons. These revisions are of central importance where the lower house is dominated by a government of strong majority. HOL purposes amendment of bill which maintains quality of statute book. It occupies largest and increasing proportion of time of the HOL. Under the parliament act 1911, 1949 the HOL has power to delay enactment of bill, propose amendments. Generally HOC give way to HOL and accept their amendments rather than risk losing a bill for lack of parliamentary time. If a bill fails to pass all its stages in a session, it will be lost and government will have to reintroduce it in next session. To avoid this situation HOC most of the time accepts the amendments by HOL. HOL has 170 independent members which insure the independence of the house, and not being accountable to the electorate results in a scrutinizing body which can review legislation in depth and free from the political and procedural controls as in HOC. The HOL proves to be more of a legitimate constitutional safeguard, rather disrespect to social equality as claimed by many. The HOL initiates the public and private bills. The HOL also performs the function of consideration of delegated legislation by scrutinizing bills with the view to establish the extent of legislative powers which parliament intends to delegate to government ministers. In other words it can be said that HOL also performs the function of scrutiny of executive.HOL also scrutinizes the private legislation. The HOL my establish select committees which are ad hoc committees to conceder matters of public importance and in depth consideration of bills. HOL reports the compatibility of bill with convention rights protected under HRA1998.
The next step to answer this question is to discuss the composition of the HOL. HOL is unelected some claim this satiation inconsistent, undemocratic and old-fashioned in a democratic society. But the advantage of an unelected chamber lies in its lack of accountability to the government of the day and the electorate. There is a considerable proportion of independent peers or cross benchers who owe no political loyalty to any party. This enhances the value of the work by HOL. The first part of composition is of hereditary peers. Hereditary peers are created under the prerogative of queen on the advice of PM. There were 759 peers, comprising around 60% of the total members of HOL. Under the HOL act 1999 the rights of most hereditary peers were removed with the government allowing 92 peers to remain until the second stage of reforms takes place. Another important part of composition of HOL is of life peers. In 1998 there were 461 peers. The award of peerage is one of the highest owners conferred in UK. They are conferred by the crown on the advice of PM. There is however, much evidence to suggest
That the system of appointment of life peers is used politically by the government which undermines the legitimacy and independence of HOL. The next part is of judicial peers which consist of all the law lords and people of legal expertise. Under CRA 2005 this part of composition is no more part of HOL, as in October 2009 the new Supreme Court was separated from HOL with its all judicial functions, and now have its own appointment system. The last part of composition is of lords spiritual. This consists of 26 archbishops of the Church of England sit in HOL.
The next point to be discussed is how the attempts are been made to strike balance between House of Commons and House of Lords. Prior to the parliament act 1911
The HOL and HOC enjoyed the same powers over legislation, with exception of financial measure which was with HOC. A conflict between HOL and HOC resulted in passage of parliament act 1911. It abolished the HOL right to reject money bills and imposed one month time limit during which HOL may consider such a bill and proposed amendments.
These amendments can either be accepted or rejected by the HOC. If the amendments are not being proposed within one month the bill will directly go for royal assent without approval of commons. Regarding non money bill, the right to rejection of bill was replaced by power to delay the bill for two years periods, over three parliamentary sessions. Then comes the parliament act 1949, which reduced the power of HOL to delay over non money bills from two years over three sessions to one year over 2 sessions, after this period if the HOL rejected a bill twice or amend it in a manner which is not up to scratch to the HOC, the government may directly go for the royal assent. Under the 1911 act the lords have the power to block any attempt by the parliament to increase its life. This is seen as a constitutional backstop against impending abuse of the power by government. These two acts have been used once in a blue moon, on occasions such as act 1949, the govt of Ireland act 1914, welsh church act 1914, the sexual offences 2000 and hunting act 2004. In Jackson v AG it was held that purpose of 1911 act was not to enlarge the powers of HOC or to delegate powers to it, but to restrict the powers of HOL to defeat measures supported by commons.
The next and most important point to be discussed to answers the question is of the reforms that opponents of HOL had focused on the chamber which according to them is undemocratic and old fashioned, preamble to the 1911 act envisaged replacing the HOL with an elected house. In parliament act 1911 the power to veto money bill was removed, moreover the HOC was given power to overrule the non money bill after 3 sessions. The parliament act 1949 amended 1911 act and reduced the power of HOL to dely a bill from three sessions to two. In life peerage 1958 the leave of absence was introduced for those who did not attended the house regularly. Almost all the peerage was turned to life peerage. As it was said that rights and honors were not be hereditary. Peerage act 1963 allowed the hereditary peers to disclaim there peerage and can vote and stand for elections. The white paper of 168 suggested that, there should be two tier houses, the first consist of 230 voting peer and second consists of peers who could attend only. The hereditary peerage was to be removed, and govt shall have small majority of voting peers in HOL. Power of delay to be reduced to 6 months. It is important to note that that in 1978 the labor party issued a statement which said, that HOL was an outdated institution and proposed the ablution of the second house. The labor discarded its stance in 1992 and proposed two stage reforms. First the removal of hereditary peers and second part of reform was regarding the composition and powers of HOL. In 1999 HOL act was passed. 92 hereditary peers were retained; this was till the second stage of reform. The ultimate goal is to reform the Hl with elected house with proportional representation. Then comes the
Wakeham Commission Report. The main focus of this commission was to move forward to the second stage of reform without any disturbance of HOC supremacy. The report said that the upper house should comprise a majority of nominated members and minority of elected members. In relation of composition thee models were given, model B which said that 87 members directly elected at the same time as the European parliament under proportional representation. For the nomination of house an independent appointment commission was to be established.20% of member to be associated to one major party. To achieve gender balance 30% of new members were to be women. Regional members to serve for 15 years term and ample steps should be taken regarding attendance in parliament. With this it is important to discuss briefly Constitutional Reform Act 2005. According to CRA2005 HOL to select its own speaker, all judicial functions have been separated with new Supreme Court and new judicial appoint commission has been created.
