Appointments of chief justice Iftikhar ch.and all pco judges before 3 November 2007 was unconstitutional because they were appointed by military dictator, never signed by democratic president
17 amendment/LFO does not have constitutional legitimacy because it was signed by military dictator, who was still in his uniform, he attained all his powers from unconstitutional decision of pco surpreme court.
So with signing of military dictator Musharaf, 17 amendment is invalid and it needs validation from present democratic parliament, till that, this judiciary is working as defacto judiciary, restoration of judiciary is invalid without validation of their original appointments.
