This is precisely the way President Ramos of the Philippines solved the Mindanao problem. The three members of the Commission were given Cabinet positions, a Secretariat etc and asked to negotiate with the Mindanao rebels. So we have a mechanism to study. There is anxiety among certain sections of Southern opinion that an implementation of the government's devolution proposals could lead to a break-up of the country. Lots of powers are reserved for the centre in the government's proposals.
Powers relating to national unity are with the centre.
Eg, totality of financial powers, security forces and the Supreme Court. However, I agree that division into eight regional governments may be wasteful and create problems of coherence in policy-making. I would prefer a two-unit model within which there is a lot of decentralization. But there is no need for eight judicial systems, eight AGs, Police Commissions, etc. This is not because I fear the Tamil region will secede but because I feel there will be lack of coherence in policy making.
