The ratified constitution contained provisions for the establishment of an autonomous region for "Muslim Mindanao", which would become effectively autonomous upon the affirmative votes of the population of those areas in special plebiscites; a guarantee that only those provinces or cities which favor autonomy would be included in the autonomous region. The MNLF and the MILF opposed this, seeing it as against the spirit of the 1976 Tripoli Agreement. The peace talks began to break down; the government wanted the new constitution as basis for continued negotiations, while the MNLF wanted the Tripoli Agreement.
