Eighteenth Amendment to the Constitution of Pakistan in the context of "President of Pakistan"

The North-West Frontier Province (abbr. NWFP), commonly known as Sarhad (lit. 'Frontier'), was a province of Pakistan from 1947 to 1955 and from 1970 to 2010; and prior, a province of British India from its establishment in 1901 to Pakistan's independence in 1947. It was established from the north-western districts of British Punjab during the British Raj. Following the referendum in 1947 to join either Pakistan or India, the province voted hugely in favour of joining Pakistan and it acceded accordingly on 14 August 1947. It was dissolved to form a unified province of West Pakistan in 1955 upon promulgation of One Unit Scheme and was reestablished in 1970. It was known by this name until 19 April 2010, when it was dissolved and redesignated as the province of Khyber Pakhtunkhwa following the enactment of the Eighteenth Amendment to the Constitution of Pakistan.

The province covered an area of 70,709 km (27,301 sq mi), including much of the current Khyber Pakhtunkhwa province but excluding the Federally Administered Tribal Areas and the former princely states of Amb, Chitral, Dir, Phulra and Swat. Its capital was the city of Peshawar, and the province was composed of six divisions (Bannu, Dera Ismail Khan, Hazara, Kohat, Mardan, and Peshawar Division; Malakand was later added as the seventh division). Until 1947, the province was bordered by five princely states to the north, the minor states of the Gilgit Agency to the northeast, the province of Punjab to the east and the province of Balochistan to the south. The Kingdom of Afghanistan lay to the northwest, with the Federally Administered Tribal Areas forming a buffer zone between the two.

The Constitution of Pakistan (Urdu: آئینِ پاکستان, romanized: Ā'īn-e-Pākistān; also known as the 1973 Constitution) is the supreme law of Pakistan. The document guides Pakistan's law, political culture, and system. It sets out the state's outline, the fundamental rights of the population, the state's law and orders, and also the structure and establishment of the institutions and the armed forces. Drafted by the government of Zulfikar Ali Bhutto, with additional assistance from the country's opposition parties, it was unanimously approved by the 5th Parliament on 10 April and ratified on 14 August 1973. The first three chapters establish the rules, mandate, and separate powers of the three branches of the government: a bicameral legislature; an executive branch governed by the prime minister as chief executive; and an apex federal judiciary headed by Supreme Court. The Constitution designates the president of Pakistan as a ceremonial Head of State who is to represent the unity of the state. The first six articles of the constitution outline the political system as a federal parliamentary republic system; as well as Islam as its state religion. The Constitution also encapsulates provisions stipulating the legal system's compliance with Islamic injunctions contained in the Quran and Sunnah.

The Parliament cannot make any laws which may be repugnant or contrary to the Constitution; however, the Constitution itself may be amended by a two-thirds majority in both the houses of the bicameral Parliament, unlike the previous legal documents of 1956 and 1962. It has been amended over time, and most recent impulses for political upgrades and reforms has been amended. Although enforced in 1973, Pakistan, however, celebrates the adoption of the constitution on 23 March—when the first set was promulgated in 1956 each and every year as Republic Day.Technically there are 26 amendments but 23 amendments were made in constitution and three were not passed by the parliament as the three amendments collapsed.
