^ Thats because the conviction was done in absentia, he never really fulfilled the punishment. He is still at large and is still operating his party because he never got to serve his term.
they all have their excuses dont they ? Altaf H living in london but still running the party .... zardari will run to Dubai and run the party through his teenage son .... nawaz sharif will run back to saudi and is grooming his son hamza sharif for the play !!!
they will continue to live as they are and nothing will change ... we are the ones who will always find excuses of why they werent held liable !
