Khwaja's son Osama Khalid had filed the petition in the Rawalpindi bench of the Lahore High Court.
In it, he had sought the registration of an FIR against militant commander Usman, Hamid Mir and others for alleged links to the murder of his father.
Judge Manzoor Ahmad Malik summoned the law officer of Islamabad to appear before him at the next hearing.
Khalid had said in his petition that his father's killing was the result of planning by Usman, Hamid Mir and others.
He also said that he had filed an application at the Shalimar police station in Islamabad for the registration of an FIR against the same persons but police had resorted to delaying tactics due to which important evidence was being lost.
Hamid Mir, an anchor of Geo News channel, has been under a cloud since a recording of a purported telephone conversation between him and militant commander Usman was leaked on the Internet.
Media reports said a report submitted to the government by three intelligence agencies had confirmed that the voice on the recording was that of Hamid Mir.
The television anchor has denied the charges levelled against him.
Islamabad: A Pakistani court has adjourned till July 12 the hearing of a petition seeking the registration of an FIR against television anchor Hamid Mir and others for their alleged links to the abduction and killing of former ISI official Khalid Khwaja.
