Go argue with those who have made laws in the National Assembly regarding ECP powers. IF KPK government had controlled administrative and management of the LB elections, today you would be jumping up and down claiming PTI made its candidates win by controlling the system and PMLN as well as others would say 'conflict of interest' and 'biased', blah blah blah.
All it takes is a little Googling and everything is there but lazy people like you want to do 'tanqeeed barai tanqeed' for point scoring against PTI. Have a good read of the following,
Constitution of Pakistan and the Election Commission
The Election Commission is a Constitutional body, responsible for organizing and conducting elections in the country. Under Article 218(3) of the Constitution, the Commission is charged with the duty of “organising and conducting elections and making such arrangements as are necessary to ensure that the election is conducted honestly, justly and fairly.” The Supreme Court of Pakistan, in its judgment in Workers Party case (Constitution Petition No. 87/2011), provided a detailed explanation of the words ‘honestly’, ‘justly’ and ‘fairly’ and explained powers of the Commission under Article 218(3) of the Constitution.
The Commission, under Article 218 of the Constitution, consists of the Chief Election Commissioner (CEC) as Chairman and four Members appointed at the recommendation of a Parliamentary Committee comprising equal members from the Treasury and the Opposition benches. Article 219 of the Constitution, charges the Commission with the responsibility of holding general elections to the National Assembly, Provincial Assemblies and the local governments, preparing electoral rolls and revising them annually as well as conducting elections to the Senate and filling up the vacant seats in the Parliament and the Provincial Assemblies. Article 140-A also gives the ECP the responsibility of holding local government elections. Further, the Commission is also empowered to appoint Election Tribunals to adjudicate upon post-election disputes.
Election Commission of Pakistan
Introduction
PTI made the wise move, and separated itself from LB elections management and police issues completely so as to stay as neutral as possible. Therefore, everything that happened on election day is ECP responsibility.
