The Twenty-second Amendment of the Constitution of Pakistan, officially known as the Constitution (Twenty-second Amendment) Act, 2016, sets to amend the procedure for the appointment, qualifications and other prerequisites for the chief election commissioner (CEC) and four members of the Election Commission of Pakistan (ECP).

The Constitution (Twenty-second Amendment) Bill, 2016 was introduced in the National Assembly of Pakistan by Zahid Hamid, then Minister for Law and Justice. The full text of the Statement of Objects and Reasons appended to the bill is given below:

This Constitutional Amendment Bill seeks to alter eligibility criteria for appointment of the Chief Election Commissioner and Members of the Election Commission of Pakistan and to provide for other related matters. At present only Judges of Supreme Court or High Court are eligible for appointment as Chief Election Commissioner or Members, respectively. After amendment, in addition to retired Judges of the Supreme Court or High Court, retired senior bureaucrats and technocrats will also be eligible for appointment as Chief Election Commissioner or a member. In order to give representation to all Provinces, out of four Members, one from each Province shall be appointed. Maximum age for appointment as Chief Election Commissioner (68 years) and a Member (65 years) is also being fixed.

Another important change relates to continuity of the Commission, whereby instead of all four members retiring together, two of the members shall retire every two and a half years. For the first term, the Commission will draw a lot as to which two members shall retire after the first two and a half years.

Other amendments provide that delimitation of constituencies and preparation of electoral rolls for elections to local governments shall also be the responsibility of the Election Commission of Pakistan.

The Bill is designed to achieve the aforesaid objects.
