The administration enjoys discretionary powers in the implementation of its decisions to manage the public utility. These discretionary powers include, but not limited to its power to amend the administrative contract when it considers it is necessary to achieve the objectives of the public utility. Therefore, this discretionary power gives the administration the right, in its sole discretion, to make an amendment to the administrative contract, either upward or downward, and in all contracts concluded by the administration, not limiting its powers like this unless there is a misuse of power.
