The anti-terrorism court in Quetta directed authorities to produce them at the next hearing of the case on November 26.
Former Interior Minister Aftab Ahmed Khan Sherpao and former provincial Home Minister Shoaib Nowsherwani appeared in court during today's hearing.
Former military strongman Pervez Musharraf, the main accused in the case, did not appear because of security threats to his life. Musharraf is being held at his home in Islamabad.
On October 9, the Supreme Court granted Musharraf bail in the Bugti murder case after accepting his appeal against the rejection of a similar plea by the Balochistan High Court.
Akbar Bugti was killed on August 26, 2006 during a military crackdown ordered by Musharraf, who was then president and army chief.
Bugti had led an armed campaign to press for provincial autonomy and a greater share of profits from Balochistan's natural resources. His death triggered angry protests across the country.
