The Senate of Pakistan is the upper house of the bicameral Parliament of Pakistan. The Constitution does not give the President of Pakistan the authority to dissolve the Senate (unlike the National Assembly). If the office of the President of Pakistan becomes vacant, or the President is unable to perform his functions, the Chairman of the Senate acts as President until a President is elected. The members of the Senate, which was originally 45, was raised to 63 in 1977 and to 87 in 1985. The government of Gen. Pervez Musharraf raised the membership of the Senate from 87 to 100 through the Legal Framework Order (LFO), 2002, enforced on 21st August, 2002. At present the Chairman of the Senate is Muhammad Mian Soomro since 2002.
