Here's a link to the draft interim constitution as formulated by the SPLM and the Government of Sudan. The draft is now being discussed and updated by the newly established constitutional review commission.
There are many clauses enshrined in this document that, if formalized, will usher in real progressive changes in the protection of the rights of all citizens, and the institution of a fairer system of power and resource allocation. It is also true that some of its clauses will have to be adjusted once the other political entities voice their opinions during the review process.
What should never be tempered with are the cardinal issues resolved during the peace negotiations between the two parties. The complete implementation of the CPA is essential if any of the other demands of all the other parties can ever get realized. Any abrogation of the basic outlines of the CPA will render the whole process a sham, and spur on other forces to reignite the conflict. The sincere implementation of the CPA will give the upcoming government of National Unity the requisite popular support and moral voice to successfully and peacefully resolve the grievances of our fellow Sudanese in the West and the East.
