Constitution is not bad at all..Infact, it is great.
All depends on IMPLEMENTATION.
See how simple that was? The CoD with PML, that also depended on implementation. The numerous other promises, they also depended on implementation. But was it implemented, no!
The government knew that Qadri was trying to find a way out, and Qadri knew that he was on his last legs. The government wanted him to get out ASAP, and Qadri wanted that as well. Both got out of this and the awaam got fooled in the process as well. Objectives achieved.
A farce declaration, that Qadri as well as anyone knows will not be implemented gave him a way out, while still keeping some izzat for himself.
