Justice Muneeb Akhtar of the Supreme Court said that the deputy speaker cannot issue such a ruling unless he is serving as the acting speaker. The bench also said that all parties concerned would be heard by the court before a verdict is announced.
Earlier, Chief Justice Umar Ata Bandial rejected Pakistan People's Party (PPP) leader Farooq Naek's request to form a full court bench.
Meanwhile, court reporter Asad Ali Toor told Friday Times that the apex court appears to be unnecessarily delaying the proceedings of an open-and-shut case.
Opposition parties had also hoped that the Supreme Court will announce a decision and put an end to the wave of uncertainty in the country that arose after the deputy speaker's ruling and President Alvi's subsequent decision to dissolve the National Assembly.
