Why do you think the Supreme Court took this case for a hearing then?
Pakistan's Supreme court has a nasty habit of political activism, more so than supreme courts in other countries.
At any rate, your additional questions to bob_chasm are negated by the PP article I posted, which demosntrated that at the very start of his rule he already owned more than enough assets to purchase this property in 2003.
Which then leaves the incorrect zoning issue. Let's start by hearing your case that he should not have been able to buy this property for housing.
