Complaining about dual standard of justice, Maryam said all standards of justice were for the Sharif family since the court was in hurry to take a decision against Nawaz Sharif in Panama Papers, resulting in his ouster as the premier.
The two sought exemption on the account of the medical condition of Nawaz's wife, Kulsoom, who is undergoing treatment for lymphoma in London. She added that her legal representative, Jahangir Jadoon, will appear in the court in case she has to go overseas.
Accountability Court Judge Muhammad Bashir had earlier reserved the verdict in both the applications.
Four witnesses have been summoned for the next hearing.
She further said that an audit report of Hudaibiya Paper Mills for the duration of 2000-2005 was submitted to the NAB.
In her application, Maryam said that she will attend the hearing whenever the court will summon her.
Former prime minister Nawaz Sharif on Wednesday vowed to take struggle against what he said double standard of courts to logical end as he appeared before an accountability court which is hearing corruption cases against him.
At the hearing of the references on Oct 9, Judge Muhammad Bashir had accepted NAB's plea to declare Hussain and Hassan proclaimed offenders and separated their trial proceedings in the three references filed against them.
After Mansoor gave her statement, NAB's second witness Ahmad presented the Sharif family's income tax returns to court. The court had also rejected the petition.
The judge also ordered that from now on they will be mentioned as proclaimed offenders in every court order.
According to Geo News, the former prime minister criticized the courts when a journalist asked him to comment on relief Imran Khan got in cases against him.
Moreover, at the last hearing, the court formally framed charges against Nawaz in person, as previously his legal representative had appeared on his behalf for the indictment on October 19 and 20.
A five-member bench of the Supreme Court on July 28 had directed NAB to file references against Nawaz and his children in six weeks in the accountability court and directed the trial court to decide the references within six months.
The three references related to the Sharif family's London flats, Flagship Investment Ltd and Al Azizia & Hill Metal Establishment.
Nawaz, along with Maryam and Safdar had earlier reached Islamabad from Lahore.
NAB's Rawalpindi branch prepared two references regarding the Azizia Steel Mills and Hill Metals Establishment, and the almost dozen companies owned by the Sharif family.
