I am usually against abrupt change. A gradual plan and detailled workout is heavily needed. A few regions should be chosen for pilot program and gradually expand elsewhere depending success/failure of the plan. But I know it would be controvertial because the leaders who are going to lose their power will oppose it heavily.

A hypothetical test case:
"empower local bodies, cut the power of central government" -- "Cease all property of corrupt people by local bodies and let them investigate without fearing the central or top-level influence"

The ward chairman of Koteswor region will be more powerful than PM Madhav Nepal in local development planning/implementation, and the ward chairman may cease Madhav Nepal's property while Madhav Nepal being investigated in corruption case at any level of the government.

Now you think, how Madhav Nepal would react in such case? will he ever allow this proposal be a law? Will he ever dare to get involved in corruption if this sort of law is there? Would he ever dare to play "halo adkayera goru chutne" game?
