Indirect expropriation in concession contract

 The work aims to demonstrate that an indirect expropriation of rights occurs when mining concession agreements are made for subsoil exploitation. The article looks at examples such as when administrative divesture for public utilities or for social interest is decreed to implement projects or environmental works; when any regulation or administrative action is taken determining protected areas or environment control of type; and when environmental control plans are implemented. The indirect expropriation occurs because a conflict exists between general interests and equality principles of the burdens, the contractual right of adherence to agreed upon provisions and the legality of prior legal regulations for the carrying out of such expropriation. 

Las regalías en Colombia y su impacto en el ámbito subnacional

Durante varios años se ha mantenido un fascinante debate sobre las regalías por lo que significanpara las finanzasde los entes subnacionales, por su impacto en el ámbito social y por su signifcado en materia tributaria para las empresas, entre otros. El objeto del presente trabajo es presentar el marco normativo que rige las regalías, las variables que las determinan desde el aspecto legal y su impacto; así como estudiar los posibles agrupamientos resultantes a nivel municipal y departamental teniendo como base un conjunto más amplio de variables diferentes al de las regalías.Respecto a los determinantes normativos se encontró que el monto de las regalías depende de la producción minera, del precio internacional del petróleo, del tipo de cambio y de la inflación. Desde el punto de vista de las entidades territoriales se encontró que las regalías asignadas dependen básicamente del PIB minero y que los ingresos tributarios departamentales y municipales no dependen del PIB no minero (PIB menos PIB minero). Finalmente, hay un grupo pequeño de entidades territoriales donde las regalías tienen cierto impacto, esto siembra una inquietud con respecto al mandato constitucional que señala que “el Estado es propietario del subsuelo y de los recursos naturales no renovables”, con lo cual el impacto debería abarcar buena parte del territorio nacional.-----For several years has been hold a fascinating debate on royalties, because of what they mean for the financesof the subnational entities, their social impact and its meaning in tax matters for companies, among others issues. The objective of this work is to present the regulatory framework governing royalties currently, show the variables that determine them from legal order and its impact; as well as studying the possible resulting groupings at the municipal and departmental levels taking as a basis a broader set of variables different of royalties.Respect to normative determinants, it was found that the amount of the royalties depends on mining production, the international oil prices, exchange rate and inflation. From the point of view of the territorial entities, it was found that assigned royalties are basically dependent on mining GDP. Meanwhile, departmental and municipal tax revenues are not dependent on GDP without mining (mining excluded from GDP). Finally, there are a small group of territorial entities where royalties have some impact, leaving some concern regarding to the constitutional mandate pointing to “the State owns the subsoil and non-renewable natural resources”, where the impact should covers most of the national territory.
