The move comes hours after the coalition partners expressed 'no confidence' in the three-member SC bench hearing PTI's election plea.
"We are considering filing references against the three judges including the Chief Justice," Sanaullah told Independent Urdu on Saturday.
He clarified that the decision to file the references hasn't been made yet but such a decision is a possibility.
Sanaullah told the interviewer that all the aforesaid judges have a long record of deciding cases against the PML-N.
"There's one decision that even a person with little knowledge of the law terms an attempt to rewriting the Constitution and it's related to Article 63-A, which resulted in the ouster of PML-N's Punjab rule."
He further said that it seems that the three judges want to decide the election case by themselves at all costs.

The interior minister detailed that the bench began from nine members and it now stands at three. "The three judges have now refused to accept the majority decision of their fellow judges."
According to the minister, 'We do not have any other avenue left to register our protest.'
A day earlier, the three-member SC bench turned down AGP Mansoor Awan’s request to form a full court to hear the petition.
According to the court, the law or the rules don’t support the composition of a full court and doing so would take the matter back to its start.
The judge also 'disregarded' the order issued by Justice Qazi Faez Isa and Justice Aminuddin Khan on his suo motu powers and said it violates the rules laid down by a five-member larger bench.
The newly-reconstructed four-member bench formed to hear the plea was dissolved again after Justice Jamal Khan Mandokhail recused himself from the case.
Following the ECP‘s decision to push the Punjab elections from April 30 to October 8 due to the financial and security agencies’ acknowledged inability to support the electoral process, the PTI filed a petition with the Supreme Court.
