The Senate passed a resolution on Wednesday against a person holding a party post after being disqualified from public office - a move aimed against deposed PM Nawaz Sharif's re-election as the Pakistan Muslim League-Nawaz's (PML-N) chief.
The resolution, presented by PPP's Senator Chaudhry Aitzaz Ahsan, pointed out that an un-elected person who has given up Pakistani citizenship, who is declared to be of an unsound mind or disqualified from holding public office by a court, can not become the head of a party and take decisions.
Last month, the Senate, despite the opposition parties' combined strength outnumbering the treasury benches, had passed the Elections Bill 2017, paving way for former prime minister Nawaz Sharif to once again take the helm of the PML-N.
The resolution passed with 52 senators voting in its favour and 28 against it.
Under The Representation of Peoples Act 1976, a disqualified person could not hold office of a party.
Ahsan said that after the new law, even someone who has given up Pakistani citizenship, who is declared to be of an unsound mind or otherwise disqualified from holding public office by a court now can become the head of a party.
It was further contended that by electing a disqualified person as a party chief, the parliament had become "exposed to becoming hostage to a person who himself is barred from entering it".
Opposing the resolution, Pakistan's Law Minister Zahid Hamid said the issue had been debated when the bill was passed and the president had also signed the bill after Parliament adopted it, it had become law now.
The resolution is non-binding and of no legal value and hence just symbolic.
