Indirectly, the Act enhanced the already dominant position of Prime Minister in the constitutional hierarchy. Although the Lords are still involved in the legislative process and the prime minister must still guide legislation through both Houses, the Lords no longer have the power to veto or even delay enactment of legislation passed by the Commons. Provided that he or she controls the Cabinet, maintains party discipline, and commands a majority in the Commons, the prime minister is assured of putting through his or her legislative agenda.
