Proven to whom?
Same judge or the bigger judge who they are saying is also biased.
Even if the lawyer somehow depicts the judge's "dil ka haal" and he refuses to accept it, then what? Since people like to mix Musharraf's other issues, I'd mix one here related to how a judge can refuse irrefutable evidence too... A few days back DNA evidence off a gang raped victim was refused because there are no 4 witnesses. Aurat ke ooper semen hai, jokeh proven hai ke alleged rapists ka hai... aur shair ke bachay main himmat thi, dil jigra tha to ask "chaar gawah hain?"
Taking Jalib's Main nahi manta, to a whole new level
Processes are always like this. They are intentionally left loose for the judgement of the court. It is assumed that they would met out justice fairly. It is the same everywhere. However this level of jugga shahi is not done. Everyone who is directly affected and can be biased would rescues themselves from such cases. But over here "Main dasna aan".
I'm not ready to blame the entire judiciary - I'm blaming the bits that I've seen wrong. It is up to judiciary if they want to ruin their name like this or not.
