The demerger process also resulted in the restructuring of the existing megacities, with both these and the demerged cities handing over massive powers over taxation and local services to the new "agglomeration councils". The makeup of these councils was based on the population of the municipalities involved, with the mayors having the right to unilaterally appoint all of the individuals who would represent their cities on the council. The resulting structure was seen by many to be less democratic than the one which had preceded it, as demerged municipalities were denied an effective voice, and the city councils of the major cities were substantially weakened by the power of the mayors to go over the heads of opposition councillors and exercise power through their appointees to the agglomeration body.
