An Accountability Court in Islamabad has indicted former Prime Minister Nawaz Sharif, Maryam Nawaz and retired captain Safdar in the NAB references.
All three accused pleaded not guilty to the charges.
Marriyum further stated that Maryam Nawaz's mom [Kalsoom Nawaz] is in poor health however she has appeared earlier than the courtroom following the instructions of her father as Nawaz Sharif himself respects authorized establishments.
Speaking over the non-appearance of the former premier's sons Hussain and Hassan Nawaz, the state minister said that they do not come within the jurisdiction of the court, and have their own way towards the legal process.
"Injustice and atrocities can not continue together", she said.
"We are not the ones to be afraid of arrests", she said. She said the government is an institution which should be respected."Each institution should do its job".
He said they have right to criticise the court's verdict claiming a "moral victory" in the Panama Papers case which disqualified Nawaz Sharif after accusing him of corruption and dismissing him on a work permit.
The Accountability Court adjourned hearing of "Flagship investment" reference till tomorrow where charges will be framed against Nawaz Sharif.
The NAB had registered three cases of corruption and money laundering against Sharif, his family members and Finance Minister Ishaq Dar in the accountability court. The court has reserved its decision on the application.
Judge Mohammad Bashir was set to indict Sharif, his daughter and son-in-law on October 13.
He had to step down as prime minister and president of the PML-N party after being disqualified by the Supreme Court.
A Sharif representative entered a not guilty plea for the sacked premier, who is now in London with his wife Kulsoom as she undergoes cancer treatment.
Sharif, who last appeared before the anti-corruption court on October 2, has faced similar challenges in the past.
The accountability court has also issued directives for Thursday's hearing. They held a protest after the police did not allow them to enter the premises.
The NAB was directed by the Pakistan Supreme Court to launch a probe into corruption charges against Sharif family.
The Supreme Court also assigned Justice Ijazul Ahsan a supervisory role to monitor the progress of the accountability court proceedings.
She said the former Prime Minister is appearing before the courts as he wanted to tell the people that he has not committed any corruption.
