Despite the evolution of the private investment promotion regime in relation to investment projects under private initiatives, there are many shortcomings in its regulation, especially at the evaluation stage, which creates serious disincentives for attracting private investors. One of these defects derives from its consideration as requests of graces and of how the Administration understands this type of petitions. Having this problem in mind, we propose a rereading of the nature of private initiatives to ensure that decisions taken by the Public Administration in this regard are subject to a true control of legality. 

The special nature of the contractor selection procedure and the source hierarchy of the State Procurement Law have been used as an argument to support the non-application of the interoperability rule within the framework of these procedures. Being in disagreement with this position, we sustain in the article that the special nature of the selection procedure does not negate the application of the informalism principle that underpins the interoperability rule. Likewise, we maintain that the common character of the Law of General Administrative Procedure, where the principle of informalism is enshrined, requires a reinterpretation of the hierarchy of sources of the State Contracting Law.

A pesar de la evolución del régimen de promoción de la inversión privada con relacióna los proyectos de inversión bajo la óptica de iniciativas privadas, persisten muchos vacíos en su regulación, sobre todo en la etapa de evaluación, lo cual genera serios desincentivos para la captación de inversionistas privados.

El presente artículo busca dar luces de la aplicación del principio de mutabilidad en la modificación de los contratos de concesión que se realizan bajo el marco jurídico de asociaciones público-privadas, dando una reflexión doctrinaria y su contraparte normativa en el sistema peruano.

The present article seeks to show the aplication of the mutability principle in amendments on concession contracts that are made on the legal frame of public-private partnership, giving a doctrinaire vision and also the Peruvian normative treatment.
