 The Reform Act strengthened the House of Commons by reducing the number of nomination boroughs controlled by peers . Some aristocrats complained that , in the future , the government could compel them to pass any bill , simply by threatening to swamp the House of Lords with new peerages . The Duke of Wellington lamented : " If such projects can be carried into execution by a minister of the Crown with impunity , there is no doubt that the constitution of this House , and of this country , is at an end . [ ... ] [ T ] here is absolutely an end put to the power and objects of deliberation in this House , and an end to all just and proper means of decision . " The subsequent history of Parliament , however , shows that the influence of the Lords was largely undiminished . They compelled the Commons to accept significant amendments to the Municipal Reform Bill in 1835 , forced compromises on Jewish emancipation , and successfully resisted several other bills supported by the public . It would not be until decades later , culminating in the Parliament Act 1911 , that Wellington 's fears would come to pass .
