1. Under Article 58 of the Pakistan Constitution, the President of Pakistan is allowed to dissolve the National Assembly on the Prime Minister's advice.
HOWEVER
A Prime Minister against whom a vote of no confidence has
NOT been voted on, the Prime Minister is not allowed to ask the President to dissolve the House
2. To get around this, the Deputy Speaker first dismissed the no confidence motion from the opposition parties, He did this on the basis of Article 5 which states the the opposition is not loyal to Pakistan thus indicating that only Imran Khan is loyal to constitution while every other member is not. (This is in fact not democracy)
So the argument is that the letter being used by Imran Khan which did not in fact prove Foreign interference in any legal or relative manner is being used to push a dictatorial push to deny the opposition right to move on with no confidence vote
One may not like the opposition and consider them corrupt but what Imran Khan and Deputy Speaker have done is no different than what Army has done for decades in Pakistan with martial law powers. If Imran Khan supporters accept this as an acceptable alternative they should accept that if Army intervenes and takes over, they will be hypocrites by calling the Army argument illegal.
Article 5 mentioned and screenshot above is about being loyal to the constitution , Imran Khan and Deputy Speaker have proven not loyal to the constitution by dismissing the opposition's constitutional right to no confidence vote.
The Deputy Speaker is only allowed to declare the results of the vote, not dismiss it before it happens.
By pushing the dismissal using Article 5, the Deputy Speaker and Imran Khan have disobeyed Article 6 of the Pakistan constitution which states:
Shame on Imran Khan for taking the law in his own hands
Shame on Deputy Speaker for helping Imran Khan taking law in his own hands
Shame on Imran Khan's supporters for being blind sheep and hypocrites
