THE
HIGH TREASON (PUNISHMENT) ACT, 1973
(LXVIII OF 1973)
Punishment for high treason : A person who is found guilty‑
(a) of having committed an act of abrogation or subversion of a constitution in force in Pakistan at any time since the twenty‑third day of March, 1956; or
(b) of high treason as defined in Article 6 of the Constitution,
shall be punishable with death or imprisonment for life.
So that means if Mush is tried, he either gets death or imprisonment for life!!
If the punishment is executed, it should put the fear of God into Pakistan's army generals thinking of a coup in future.
And Mush's strategy of coming back to Pakistan and making a splash in politics has backfired spectacularly just like his Kargil fiasco! That's why they say that generals should stick to sand model discussions and making battle plans rather than meddle in politics which they haven't a clue about.
