Nawaz Sharif was disqualified for holding any public office by SC for lying. And then convicted by NAB in the Avenfield reference for 10 years for assets without means. He was sent abroad after massive pressure from the courts on Shahbaz's guarantee. Which he flouted and became an absconder.
So an ordinary absconder gets a diplomatic passport?
1)
Nawaz Sharif was disqualified under article 62 of constitution of Pakistan, for not mentioning receiving x amount of salary, in his election filling papers. (salary) which he allegedly use to withdraw while being employed as a manager in his son's company, which was registered in UAE.
Verdict thus far is conflicted by many legal experts. There exist difference in interpretation of implementation of article 62 aka (defining sadiq amin)
specially when Nawaz Sharif claims, that he never received any amount, as a salary in any of his bank accounts, hence he has correctly declared his earnings, which exclude mentioning any salary.
(I think judiciary should have advised the govt. to ask for company's financial records, which can prove if any salary was transferred to Nawaz Sharif, while being employed, or not)
P.S.: after Khan assumed power, many political rivals of Imran Khan were disqualified using article 62.
2)
NAB is an organization responsible for inquiry and asset recovery, all convictions come from courts.
Until convicted from courts, all of the process at NAB at best is called REFERENCE!
In Pakistan's judicial system, cases of conviction from lower courts, always got challenged in higher courts, which is business as usual, whereof decision may or may not be in line with verdicts of lower courts.
While the basis of case against Nawaz Sharif, as you mentioned was of money laundering to UK and buying Even field apartments from that money, which if proven right makes Nawaz Sharif criminal in 2 states, but NAB decided not to pursue that case in UK courts, but
NAB did lost an arbitrary case against a UK based asset tracing company which was hired by NAB to trace finances of Even Field apartments.
In parallel yet unprecedently, NAB filed money laundering case in UK courts against brother of Nawaz Sharif and his son, but once more
NAB was booted out by UK courts. Serving blow to apparently politically motivated references constructed by NAB against Sharif Family and that of verdicts of anti-corruption courts run by FIA.
This
statement of Broadsheet also cast doubt on, apparently a case of vilification against Nawaz Sharif Family by a republic turned into banana republic by Imran Khan and abettors.
P.S.: I have no sympathy towards Sharif family, but i always hold empathy above personal grudge.
3)
He (NS) was sent abroad after various medical boards constituted by Imran Khan and party, who agreed in written to his ailing health conditions based on various lab tests, even than his travel abroad had to be
endorsed by courts, following the legal course, he eventually boarded the plane.
His treatment in UK was investigated by govt. of Pakistan, following his passport was cancelled, barring him to travel as a consequence he was declared absconder due to his absence from courts, where he was facing hearings of cases resulting from NAB's corruption references. Before passport there was COVID outbreak and Pakistan was isolated from world due to no flights. UK as well was locked down.
4)
Passport is right of every citizen. Now since regime change has happened in Pakistan, he's going to get his passport back.
Green or Blue, i can't confirm but it makes no difference, since it will be used to travel back to Pakistan and have no impact on his legal proceedings.
