The financial equalisation system in France has become crucial in the management of local authorities. By way of illustration, there is an ongoing growth of financial resources, systems and plans of action to reduce inequalities between local governments and districts. Despite the encouraging results in the national equalisation implementation, its consistency and complexity mechanisms are to be enhanced. The disability to define freedom and equality contains the legislator in the design of stable and defined framework for equalisation. As such, the theory on a uniform distribution raised since the Age of Enlightenment, is to be considered. Unlike the German laws and regulation, the legislator is free to set up rules of financial interdependency among local authorities in the French Constitution. The constitutional judge, precursor and equalisation decision-maker, supervise an insufficient control to the detriment of financial and fiscal autonomy of local authorities. From the basis of equalisation benefits, there are some evident difficulties surrounding the limit of this system in respect to the degree of local authority’s financial autonomy. An operational review of both horizontal and vertical equalisation mechanisms, as well as the choice of redistribution criteria should be undertaken. The stakes are high to adjust and put right the shortcomings of the equalisation system, recently modified by a financial regulation reform for 2010 and 2011.
