Musharraf's treason trial

Re: Musharraf’s treason trial

Assuming your argument is valid in scenario 1 and Mushy was legally justified in declaring emergency in the country than how do you explain:

  1. He did that as an army chief & not as the president (thus it would be considered a coup invoking article 6)
  2. What was the legal justification for suspending the Constitution?
  3. If you read the Constitutional it clearly states that joint sitting of the parliament must approve presidential actions, and that never happened.
