Was case against CJ’s son decided before it began?

Chief Justice with his sonWas the corruption case against Arslan Chaudhry decided before it even began? A New York Times article about the case against the Chief Justice’s son includes a particularly interesting paragraph:

Mr. Mir then insinuated that the powerful army and intelligence services could be manipulating Mr. Hussain in order to get at Justice Chaudhry for his relentless pursuit of cases related to illegal detention and extrajudicial killings by the security forces. “Now you are going in the right track,” Justice Chaudhry said with a faint smile.

How does the Chief Justice know what is the right track before he has heard all the evidence? Has he already decided the outcome and now he is leading the witnesses to provide the testimony needed to give the decision already made?

The Chief Justice has now recused himself, but is it not a case of too little too late? How can anyone be expected to believe that the process has not been influenced when the Chief Justice of the Supreme Court gives away the ending in the first act?
