Corruption proven to whom? Reference was sent to SJC so that judges in SJC would investigate (as however obvious the allegation, right to investigate and make report on content of reference was of SJC … not any one else). It was duty of SJC to send result of investigation to President and it was duty of President to look at the report of SJC on reference and make judgment, then decided to sack or keep Iftikhar … that is legal way.
But when corrupt and crook judges of Supreme Court illegally stopped SJC to investigate (they did that in same way as judges of SC through out history of Pakitan validated every Martial Law in the country and also gave martial law administrator (Ayub, Yahya, Zia and Musharraf) the right to change constitution … and thus however illegal, every martial law becomes legal), so what was/is left there to prove?
If SC judgment to stop SJC to investigate Iftikhar was legal (however illegal) than SC judgment of validating every military takeover was legal too (however illegal) and in same way imposing emergency on 3rd Nov by Musharraf was legal too (as SC judges validated that).
Actually, SC judges should not interfere or stop SJC from investigating any Judge else that means making Judge immune from investigation. Stopping SJC from investigation is worse than SC validating martial law. Martial law cases come to SC asking for validation and they validate that (considering their judgement coming from laws of necessity) but SJC investigation is completely an independent issue and courts should not even look at that.
Issue to stop investigation of SJC on any judge do not and cannot come to SC as investigation is not case but investigation, like police investigation of any person so that person can be implicated in crime case or not. SC judges stopping SJC investigation of Iftikhar was same as SC Judges stopping police from investigating murder. It is ridiculous to even think that judges stopping investigation, as duty of judges is to give verdict taking account of investigation results, how can they stop investigation itself? But then they are Pakistani Judges and acted in self-defence, legal or illegal, possible or impossible, logical or illogical does not matter … and fortunately for them, they have similar public too for whom absurdities of any sort does not matter :D.
Well well … are we discussing Musharraf? :halo:
Anyhow, it is not only Musharraf, this can be said regarding all who ever had power in Pakistan (even power in any small organisation), as when they can, they all violated laws and constitution. Only difference is that others including Ayub, Yahya, Bhutto, Zia, BB, NS, Iftikhar, well … many who have violated laws in Pakistan, they do that without need or in self-defence (to save own life), but army on behalf of Musharraf did that in self-defence, and there is natural law of preservation, that says that all violation of laws in self-defence is not considered as violation. Even in Islam, a person can even eat Haram to preserve his existence or can kill others if his life gets in danger from that other.
Yea … I can understand that to stop from finding yourself guilty, you believe in using judges of Supreme Court to stop investigating authority or police from investigating you. You have nice believe, that is: Na ho baans na bajay bansree … na ho investigation na payea jayoon guilty aur na ayea koyi judgment. You are good student of people like Iftikhar … aap kay kiya kahnay hain
