1st, funny that you would bring up article 62. Do you know who inserted article 62 in the Constitution? Yea, Zia-ul-Haq. It was not originally part of the constitution.
2nd, what is good character & how do you quantify that?
3rd, regardless of how he was elected, his election now cannot be called into question.
BTW, degree requirement isn’t there anymore. It was thrown out by your beloved the CJ.
