Manning and Reform also continued to pressure the government on the issue of Senate reform, but the Liberals argued that this could only be accomplished by a constitutional amendment and that the country was weary of constitutional matters. On April 20, 1998, Manning gave the longest and most comprehensive speech on Senate reform given in the House of Commons in the 20th century. In it he described in graphic detail the major defects of the Senate and the inappropriate, patronage infected behaviour of many of its members. He then reviewed all the previous major attempt at Senate reform and the reasons for their failure, concluding with the case for Reform's Triple E Senate. The government was unmoved, and Senate reform was not pursued in earnest again until the Harper government introduced Senate reform legislation embodying two-thirds of the Triple E Senate concept in 2007. When referred to the Supreme Court, however, the court ruled that the federal government could not unilaterally make the changes contained in the bill and once again Senate reform was stalled indefinitely.
