Former military ruler, through his lawyer Farogh Nasim, sought a copy of the investigation report on the basis of which the treason case has been initiated against him.
Nasim also asked the court to provide the dissenting note written by a senior official of Federal Investigation Agency.
A three-judge bench, headed by Justice Faisal Arab of the Sindh High Court, heard the case pertaining to high treason charges against 70-year-old Musharraf.
The defence presented the notification issued for the declaration of the emergency in 2007 and said the names of the people who were consulted regarding it were included in the order.
Nasim argued that according to the law, all those involved in the alleged crime should be tried together to which Justice Arab replied that the special court does not have the authority to hear other cases.
The lawyer argued that the Federal Investigation Agency's report had also not been made public yet.
Nasim claimed that a member of the investigation committee wrote a dissenting note which was not included and questioned the prosecution's motives for excluding the note.
Musharraf's lawyer argued that the decision related to the appointment of the prosecutor in the case was still pending and the court in its ruling of March 27 had said a ruling would be announced before the start of the testimony.
The court adjourned the hearing of the case until tomorrow after listening to the arguments of both parties.
Since Musharraf returned to Pakistan from self-exile in March last year, he has faced prosecution in four major cases, including for his alleged involvement in the murder of former prime minister Benazir Bhutto in 2007.
The former president, who is the first military ruler in Pakistan's history to be tried in court, has rejected all the charges leveled against him.
