No reason was given for why it was rejected, and where is the supervising SC judge? has the SC made a deal and not following up? And where is Imran Khan? he said he would follow NS to his grave, looks like he is not interested in following up this case now. In his place, you have Sheikh Rashid who is begging around and making petitions (Hudaybiya) to follow up. Why isn't PTI with its financial and legal power following up? last hope is the accountability court judge who has powers to do this.
In criminal cases, individual like IK/PTI can't file or contest case under Anglo Saxon Law. Only government can go to court against criminal. Unfortunately criminals are part of government and they are not going to follow case against criminals in court especially when they are powerful.
