Revisión de los contratos administrativos: el adecuado equilibrio entre potestades exorbitantes y los derechos contractuales

The purpose of this article is to analyze the requirements and conditions that must be met in order to maintain the economic and financial balance in administrative contracts in the face of changes arising from the exercise of public powers of the Contracting Authority. Unilateral contract modifications introduced by the contracting State are analyzed, such as those based on the issuance of general rules issued by other State bodies, such as the legislative power or the executive power in the exercise of regulatory power. Finally, we study the contractual changes derived from events unrelated to the will of the parties, unforeseeable and irresistible that make the fulfillment of contractual obligations excessively onerous.
